In the case titled Atiabari Tea Co., Ltd. versus The State of Assam and Others, the judgment was delivered on 26 September 1960 by the Supreme Court of India. The bench that heard the matter comprised Justice B. P. Sinha, Justice J. C. Shah, Justice K. C. Das Gupta, Justice K. N. Wanchoo and Justice P. B. Gajendragadkar. The opinion was authored by Chief Justice Sinha.

The matters before the Court arose from appeals that were supported by certificates issued under article 132 of the Constitution by the High Court of Judicature at Assam. In addition, the parties had filed writ petitions under article 32 of the Constitution. All of these proceedings challenged the constitutional validity of the Assam Taxation (on Goods Carried by Roads or Inland Waterways) Act, identified as Assam Act XIII of 1954, and the Act will be referred to subsequently simply as “the Act.” The appellants had originally approached the High Court of Assam invoking article 226 of the Constitution, seeking a declaration that the Act was invalid. The High Court, by its judgment and order dated 6 June 1955, dismissed the writ petitions. Following that dismissal, the appellants succeeded in obtaining certificates from the High Court stating that the questions raised involved substantial issues of law concerning the interpretation of the Constitution. Consequently, the appellants filed petitions under article 32 of the Constitution in this Court for the purpose of contesting the validity, or “vires,” of the Act. For convenience, the judgment will refer to the appellants and petitioners collectively as “the appellants.” The respondents to the appeals and the writ petitions were the State of Assam, the Commissioner of Taxes appointed under section 6 of the Act, and the Superintendent of Taxes.

The factual backdrop shows that the appellants were tea growers operating either in West Bengal or in Assam. They transported their tea to the market in Calcutta, from where the tea was either sold for domestic consumption throughout India or exported for sale abroad. The volume of tea sold within Assam constituted only a very small fraction of the total tea produced and manufactured by the appellants. The great majority of the tea output was therefore carried out of Assam, either for internal consumption elsewhere in India or for export overseas. While a portion of the tea was moved by rail, a substantial quantity was conveyed by road or by inland waterways from Assam to Bengal. In certain instances the tea travelled from one part of West Bengal to another part of the same state using inland waterways, a route that included only a few miles of passage through the territory of the State of Assam. The Assam legislature enacted the Act, which received assent from the Governor of Assam on 9 April 1954 and became effective on 1 June 1954. The purpose of the Act was to levy taxes on specified goods that were carried by road or by inland waterways within the State of Assam. On 30 June 1954, the second respondent, the Commissioner of Taxes of Assam, exercised the authority granted to him by sub‑section (3) of section 7 of the Act and issued a notification in the Assam Government Gazette dated 21 June 1954. The notification announced, for general information, that returns required under the Act and the rules made thereunder for the period from 1 June 1954 to 30 September 1954 were to be filed by 30 October 1954.

On June 30, 1954 the Commissioner of Taxes, Assam, exercised the authority granted by sub‑section (3) of section 7 of the Assam Tea Industry Taxation Act and issued a notification in the Assam Government Gazette dated June 21, 1954. The notification directed that all returns required under the Act and the rules made thereunder for the period beginning 1 June 1954 and ending 30 September 1954 must be filed no later than 30 October 1954. It further required that quarterly returns for the quarter ending 31 December 1954 be filed by 30 January 1955 and that returns for the quarter ending 31 March 1955 be filed by 30 April 1955. In several instances the appellants, after receiving demand notices, filed the required returns with the Superintendent of Taxes using the prescribed form for tea dispatched and carried up to 30 September 1954, but they did so under protest and also paid the tax that was demanded under protest. The appellants then approached the High Court of Assam invoking Article 226 of the Constitution, seeking to set aside the Act as unconstitutional and requesting the issuance of a writ of mandamus to restrain the respondents from implementing the provisions of the Act and the related notification, or alternatively a writ of prohibition or any other appropriate writ to prevent the respondents from taking steps under the Act.

The appellants challenged the validity of the Act on three principal grounds. First, they argued that the Act, its rules and the notifications issued thereunder exceeded constitutional limits because the tax on the carriage of tea through Assam conflicted with Article 301, which guarantees freedom of trade, commerce and intercourse. Second, they contended that tea was a controlled industry under the Tea Act XXIX of 1953, and therefore only the Union Government possessed the power to regulate the manufacture, production, distribution or transport of tea, effectively ousting the jurisdiction of the Assam legislature. Third, they maintained that the tax imposed by the Act was, in substance if not in form, an excise duty and therefore intruded upon the Union’s legislative competence under entry 84 of the Union List. Additionally, the appellants asserted that the Act was discriminatory and consequently void under Article 14, and they questioned the very competence of the Assam Legislature to legislate on the subject. The respondents, representing the State, opposed these petitions in the High Court, denying that the Act, its rules, or its notifications were ultra‑vires, and rejecting the claim that the Act violated Article 301, encroached upon Union legislative powers, conflicted with the Tea Act of 1953, or was discriminatory. They argued that the Act was, in its pith and substance, a law to levy tax on certain classes and types of goods carried by road or inland waterways, and that such taxation fell squarely within entry number 56 of the State List, thereby confirming the legislative competence of the Assam Legislature.

The petitions were examined by a Special Bench of the Assam High Court, which on 6 June 1955 delivered a judgment dismissing the objections and holding that the Act was not unconstitutional. The bench issued two separate but concurring opinions, one authored by the Chief Justice, Sarjoo Prasad, and the other by Justice Ram Labhaya. The Chief Justice explained that the legislation contemplated the imposition of a tax on the transport or carriage of goods, which fell squarely within entry 56 of List II of the Constitution. He observed that this tax did not interfere with the freedom of trade and commerce as protected by Article 301, because the essence of the impugned Act was a fiscal measure rather than a direct regulation of trade. Accordingly, Article 301 was not directly applicable to taxing statutes. The Chief Justice further held that the levy imposed by the Act was not an excise duty and that the claim that it encroached upon entry 84 of the Union List was unfounded. He also concluded that the Act did not conflict with the central legislation governing the tea industry, namely the Tea Act XXIX of 1953.

Justice Ram Labhaya undertook a detailed analysis of the provisions of the Act and determined that the requirement that carriage be a condition of liability created a distinction from an excise duty, placing the tax within entry 56 of List II. He stated that taxation in itself does not abridge or curtail the freedom guaranteed by Article 301, while Articles 302 and 304 limit the legislative powers of Parliament and the State in matters covered by entries 42 of List I, 26 of List II, and 33 of List III. He further noted that any restrictions on the movement of goods and traffic must find justification in Part XIII of the Constitution. According to Justice Labhaya, the Act’s provisions for taxation did not directly impinge upon the freedom of trade, commerce, and intercourse as envisaged by Article 301, although he acknowledged that taxation could, in certain circumstances, restrict movement of goods, thereby falling within the mischief addressed by Article 301. Consequently, he concluded that the true substance of the Act lay within the scope of entry 56 of List II. In examining the Union legislation, Justice Labhaya found that the Tea Act No. XXIX of 1953 was not infringed upon by the impugned Act.

The Court observed that the impugned Act did not intrude upon the field of the controlled tea industry. In addressing the argument that the Act discriminated in violation of Article 14, the Court noted that no evidence was produced to show any real discrimination between persons or things. The third judge, Deka J., fully concurred with these conclusions. The appellants, having obtained certificates of appeal from the High Court, challenged the High Court’s judgment. In addition, two separate petitions filed under Article 32 of the Constitution on behalf of other tea producers raised the same issues that were to be decided in the three appeals arising from the Assam High Court’s decision. All of these matters were heard together, and the Court directed that they would be resolved by a single common judgment.

Mr Chatterjee, appearing for the appellants, set out several contentions. He argued that the impugned Act placed restrictions on the free flow of trade and commerce in tea and jute, the two commodities covered by the Act, and therefore violated Article 301 of the Constitution. He further asserted that the legislation exceeded the legislative competence of the Assam Legislature because it was not authorized by entry 56 of List II. He maintained that the tea industry was a controlled industry declared by Parliament and fell directly under entry 52 of List I. He described the Act as a colourable piece of legislation whose true effect was to levy an excise duty, a power that could only be exercised by the Union Legislature, and he also claimed that the Act contravened Article 14 of the Constitution. In response, the Learned Attorney General, on behalf of the State of Assam and the Union, contended that mere taxation was not covered by the terms of Article 301. He explained that taxation as such is not a restriction within the meaning of Part XIII; it is an attribute of sovereignty and is not justiciable. The power to tax, he said, is a special legislative function that courts do not directly examine, and consequently the freedom contemplated by Article 301 does not mean freedom from taxation. He clarified that “Restriction” in the context of Part XIII refers to legislation that impedes the free flow of goods and traffic by erecting tariff walls; such tariff walls, if created by a legislature, may be justiciable, but legislation that simply imposes a tax for revenue purposes is not. He further argued that Part XII of the Constitution is a self‑contained part dealing with finance, while Part XIII is a self‑contained part dealing with trade, commerce, and intercourse within the territory of India. He emphasized that decisions from the United States and Australia are not persuasive in this case because the constitutional frameworks of those countries differ entirely from that of India, noting particularly that the Australian Constitution contains no provisions corresponding to Parts III and XII of the Indian Constitution.

According to the argument presented, the term “freedom” in Part XIII was understood to mean freedom from discriminatory taxation as well as freedom from trade barriers. The Advocate‑General of the several states who appeared in the proceedings supported the viewpoint emphasized by the Learned Attorney‑General. The central issue that required determination in this series of cases was whether the impugned statute violated the provisions of Part XIII of the Constitution, with particular reference to Article 301. Part XIII carries the heading “Trade, Commerce and Intercourse within the Territory of India”. Article 301, which opens this part, states in broad terms: “Subject to the other provisions of this part, trade, commerce and intercourse throughout the territory of India shall be free.” It is clear from the language that this part is not constrained by other provisions of the Constitution; the generality of the words used in Article 301 is narrowed only by the other articles contained in the same part, concluding with Article 307. Consequently, it could not be argued that the general expression in Article 301 admits any exception or explanation that does not arise within Part XIII itself, nor could it be said that trade, commerce and intercourse are subject to any other restraints. All parties agreed that the Constitution emphatically declares trade, commerce and intercourse throughout India to be free, but they differed sharply on the question “free from what?” The appellants contended that the freedom must be understood to mean freedom from all impediments, including taxation. In contrast, the Union Government and the State Governments maintained that the freedom envisioned by Article 301 does not encompass immunity from taxation; rather, it means that there shall be no trade barriers, tariff walls, or restrictions that shut out commodities, traffic or intercourse between individuals, and no measures that de‑stock the market.

To fully appreciate the implications of the provisions of Part XIII, it is necessary to consider their historical background. The Constitution Act of 1935 (Government of India Act, 26 Geo. 5, Chapter 2) had envisaged a federal constitution for the whole of India, including both the territories then known as Indian India and British India, and introduced full provincial autonomy. That Act enacted Section 297, which prohibited certain restrictions on internal trade. Section 297 reads: “No Provincial Legislature or Government shall, by virtue of the entry in the Provincial Legislature List relating to trade and commerce within the Province, or the entry in that list relating to the production, supply, and distribution of commodities, have power to pass any law or take any executive action prohibiting or restricting the entry …” and further states that no law passed in contravention of this section shall, to the extent of the contravention, be invalid. The prohibition contained in the quoted section applied solely to provincial governments and legislatures with respect to entries in the Provincial Legislative List concerning trade, commerce, and the production, supply and distribution of commodities. The provision dealt with prohibitions or restrictions on the import into or export from a province of goods generally, and also addressed the power to impose taxes, cesses, tolls or dues that discriminated in favour of goods manufactured or produced within the province.

The provision quoted from the earlier statute prohibited any provincial authority from imposing a restriction on the import into, or export from, a province of goods of any class or description. It also barred a provincial legislature or government, by virtue of any provision of that Act, from imposing any tax, cess, toll or other demand that discriminated in favour of goods manufactured or produced within the province against similar goods not so manufactured or produced. Likewise, the provision forbade any tax or duty that, in relation to goods manufactured or produced outside the province, treated goods from one locality more favourably than similar goods from another locality. The statute further declared that any law enacted in contravention of these restrictions would be invalid to the extent of the inconsistency.

It is important to observe that the prohibition contained in the quoted section applied solely to provincial governments and provincial legislatures, and only with respect to entries in the Provincial Legislative List dealing with trade and commerce within the province as well as the production, supply and distribution of commodities. The section therefore addressed prohibitions on the import into or export from a province of goods in general, and it also regulated the power to impose taxes, cess, tolls or other dues, disallowing any discrimination against goods manufactured or produced outside the province or against goods produced in different localities within the province. Part XIII of the Constitution later extended all of those prohibitions beyond the provincial sphere to include the Parliament of India and the State legislatures. In effect, Part XIII broadened the scope of the restraints and set the limits within which the Union Parliament or any State legislature may legislate on matters of trade, commerce and intercourse, whether inter‑State, intra‑State or throughout the entire territory of India.

To understand the significance of these constitutional provisions, one must recall the situation existing before the Constitution came into force. Approximately two‑thirds of the Indian subcontinent was directly administered by the British and was referred to as “British India,” while the remaining one‑third consisted of princely or “Native States” ruled by local princes who possessed varying degrees of sovereignty. These native rulers exercised the attributes of sovereign states, including the authority to levy taxes and to regulate the flow of trade, commerce and intercourse. Many of them erected trade barriers that severely obstructed the free movement of goods, both by shutting out external commodities and by preventing the internal circulation of goods meant for mass consumption. Between 1947 and 1950, almost all of these Indian States entered into agreements with the Government of India and eventually merged their separate identities into a single political entity. Consequently, the territories formerly known as British India were classified under the Constitution as Part A States, while the native princely territories, subject to certain exceptions not relevant here, became Part B States. Prior to the constitutional classification of Part A, Part B and Part C States (excluding Part D, which related to other territories), the entities that later formed Part B comprised numerous small princely units, many of which had themselves formed unions and maintained internal customs posts and trade barriers.

Before the political integration of the Indian territories, a number of native States formed unions among themselves and each of these unions maintained trade barriers and customs posts, even in transactions that occurred between the States themselves. After the merger of these States into a single nation, the Constitution was required to acknowledge the continued existence of such barriers and therefore incorporated transitional provisions whose ultimate purpose was to eliminate all of them. The former native States, regardless of their size, each imposed their own taxes, cases, tolls and other imposts and duties. These fiscal demands were not solely meant to raise revenue; they also functioned as trade barriers and as tariff walls that restricted the free movement of commerce. In light of these circumstances, the Constitution, through Article 301, mandated the abolition of all such trade barriers and tariff walls. When, for the first time in Indian history, the entire territory within the geographical boundaries of what is now India—excluding the area that became Pakistan—was united into one political unit, it became necessary, in the interest of national solidarity, economic and cultural unity, and the freedom of trade, commerce and intercourse, to remove every customs post and trade barrier that persisted.

The background of these facts and circumstances required the Court to determine the scope of the freedom guaranteed by Article 301. That article envisages not only the freedom of trade and commerce between the different parts of India but also the freedom of movement of individuals in relation to their trade and other activities. Consequently, Article 301 refers not only to trade and commerce as commonly understood, but also to the ability of individuals to carry their goods and commodities throughout the length and breadth of the country. The movement of goods, commodities and persons may be undertaken by railway, air, road or inland waterways. Carriage of goods and passengers by railway, sea or air, as well as national waterways, falls under entry 30 of List I of the Seventh Schedule, and taxes on railway fares, freights and terminal charges on goods or passengers carried by these modes are covered by entry 89 of the same List. By contrast, taxes on goods and passengers conveyed by road or inland waterways are placed under entry 56 of List II, the State List. Thus, the Constitution‑makers contemplated that the Parliament could impose taxes on journeys made by railway, sea or air, while State Legislatures could impose taxes on journeys made by road or inland waterways. The power to tax is an inherent attribute of sovereignty. The sovereign authority—sometimes the Union, sometimes a State—possesses the inherent power to levy taxes in order to raise revenue for governmental purposes. This sovereign power is ordinarily non‑justiciable, because it is the legislative branch of the State that determines the policy and incidence of taxation. It is the State, through its Legislature, that decides what taxes to impose, on whom, and to what extent. The judicial department of the State

The judgment explained that the judiciary is not expected to involve itself in questions of tax policy or the incidence of taxation, because such determinations belong to the legislative branch. The power of the State to raise finances for governmental purposes is addressed in Part XII of the Constitution, which enshrines the absolute prohibition on the levy or collection of any tax except by authority of law, as embodied in Article 265. Part XII also deals with the distribution of revenue between the Union and the States, but it does not provide a clear demarcation of taxing authority between the two levels of government. Consequently, Part XII had to set out in detail which taxes are to be levied for the Union’s benefit, which are to be levied for the States’ benefit, and the principles by which those revenues must be distributed among the constituent states of the Union. In summary, Part XII constitutes a self‑contained series of provisions governing the finances of the Union and the States, their inter‑relations and adjustments, while intentionally ignoring the provisions relating to borrowing in Chapter 2 and to property contracts in Chapter 3 of the same part. Like Part XIII, Part XII is not expressed as being subordinate to any other constitutional provisions; therefore both Parts XII and XIII are intended to operate autonomously within their respective fields and one cannot be said to be subject to the other. The appellants contended that the provisions of Article 304 indicate that taxation falls within the scope of the overriding provisions characterised in Article 301. However, a careful examination of Article 304 shows that it is divided into two distinct segments: the first segment deals with the imposition of discriminatory taxes by a State Legislature, while the second segment concerns the imposition of reasonable restrictions, thereby demonstrating that the power to levy taxes—whether discriminatory or not—is a separate matter from the power to impose reasonable restrictions on the freedom of trade, commerce and intercourse. The second segment of Article 304, which addresses reasonable restrictions imposed by a State Legislature on the freedom of trade, commerce and intercourse, is parallel to the power of Parliament to impose such restrictions between States or within any part of the territory of India in the public interest, as provided in Article 302. Moreover, the provisions of Article 303 clarify that granting preference to one State over another or discriminating between States falls squarely within the ambit of Part XIII, meaning that such actions are intended to impede the freedom of trade, commerce and intercourse. Accordingly, both Parliament and State Legislatures are prohibited from enacting any law that gives preference to one State over another or that authorises any discrimination between States. But the most significant words in connection with giving

In the judgment, the Court explained that the permission to give preference or to discriminate, as mentioned in Article 303, related specifically to “any entry relating to trade and commerce in any of the lists in the Seventh Schedule,” namely entry 42 in List I, entry 26 in List II and entry 33 in List III. Accordingly, any law that directly interfered with the free flow of trade, commerce or intercourse throughout the territory of India had to be declared void as a violation of Article 301. The Court further noted that the Constitution’s framers had considered emergencies, such as floods that caused scarcity of essential commodities like food grains. In such circumstances, Parliament possessed the authority to grant preference to one State over another or to discriminate among States, provided that the legislation dealing with the emergency expressly declared such measures necessary. The Court emphasized that the wording of Article 303 was precise, observing that the non‑obstante clause at the beginning of the article referred only to Article 302, which empowers Parliament to impose by law restrictions on inter‑State or intra‑State trade, commerce or intercourse in the public interest. Immediately after, the provision also extended the power to the legislatures of the States to give preference or discrimination with respect to the trade‑and‑commerce entries in the Seventh Schedule, while making no reference to intercourse. Since the present dispute did not concern the freedom of intercourse, the Court stated that no further comment on that omission was required. Counsel for the appellants had argued aggressively that the freedom guaranteed by Article 301 should be interpreted in its broadest possible sense, encompassing freedom from all impediments, restraints, trade barriers and even all forms of taxation. The Court rejected this extreme view, recalling that trade, commerce and intercourse also embodied the individual right of every citizen to move freely from one State to another, a right protected by Article 19(1)(d). The three terms in Article 301 covered not only the unrestricted buying and selling of goods, but also the freedom to bargain, contract, transmit related information and transport goods by land, air or sea for production, distribution and consumption. Moreover, commerce extended to the movement of persons and animals by any means of transport. Consequently, the Court held that the appellants’ expansive interpretation of Article 301 was unfounded.

Thus, the freedom guaranteed by Article 301 embraced transactions conducted through telegraph, telephone, wireless and every form of contract involving the sale, purchase, exchange and similar dealings of goods and commodities. In viewing the article in this all‑encompassing manner, the imposition of taxes on trade, commerce and intercourse would generate far‑reaching consequences, extending to virtually the entire field of public taxation covered by both the Union and State Lists. It was implausible to assume that the Constitution’s framers intended to exempt trade, commerce and intercourse from taxation in such a sweeping sense. Were that the case, every law imposing tax on the sale and purchase of foodstuffs, on the carriage of goods, commodities, men or animals from one place to another—whether the movement was inter‑State or intra‑State—would fall within the ambit of Article 301, and the proviso to Article 304(b) would compel all bills, amendments and existing statutes to conform to the procedure prescribed therein. Such a result would impose an excessive barrier to the States’ taxation powers and would reduce the limited sovereignty granted to the States under the Constitution to a mere illusion. Consequently, that extreme position was rejected as untenable. It was also pertinent to recognise that taxation did not necessarily constitute an impediment or restraint on trade, commerce and intercourse. On the contrary, taxes could furnish the resources needed to improve various modes of transport. For example, in cane‑growing regions, the absence of good roads could impede the movement of sugarcane from fields to mills; to construct new roads or upgrade existing ones, a cess on cane growers or others interested in transporting the commodity was imposed, often calculated per maund or ton of sugarcane moved to factories. This levy, being a tax on the transport of sugarcane—whether inter‑State or intra‑State—generated the revenue required for establishing new communication facilities or enhancing existing ones. Similarly, a surcharge on passenger fares or freight charges might be levied to fund improvements in motor‑vehicle or railway services, although such surcharges did not always result in corresponding infrastructure upgrades. Therefore, it could not be said that every tax on the movement of goods or passengers automatically signified an obstruction or restraint on trade and commerce. This observation provided an additional reason to conclude that taxation was not ordinarily encompassed within the terms of Article 301.

The Court examined Article 301 of the Constitution and expressed the view that a tax levied in its ordinary sense does not fall within the scope of that article. In the Court’s reasoned opinion, taxation, by definition, is the power of the State to obtain revenue for public purposes by obligating both natural persons and juristic persons to pay amounts of money that they have earned or possess, and this obligation arises because the State provides facilities and protection to them. The burdens imposed, whether they are direct or indirect, are ultimately intended as contributions by the citizens, by persons residing in the State, or by those dealing with the State’s citizens, each according to their respective capacity to contribute. Consequently, the notion of public purpose is implicit in every act of taxation.

Because of this inherent public‑purpose character, when Part XIII of the Constitution speaks of the imposition of reasonable restrictions in the public interest, the Constitution could not have been intended to include ordinary taxation within the generic term “reasonable restrictions”. The Court referred to the decision in Ramjilal v. Income Tax Officer, Mohindargarh ([1951] S.C.R. 127, 136), which held that the imposition and collection of taxes under the authority granted by Article 265 lies outside the expression “deprivation of property” found in Article 31(1). In most cases, the reasonable restrictions contemplated in Part III or Part XIII are less severe than a total deprivation of property rights. Accordingly, Part XII, which deals with finance, has been treated as the portion of the Constitution that addresses the sovereign power of the State to impose taxes, a power that always means placing burdens on citizens and others in the public interest.

If a legislative enactment imposes a tax whose true nature and effect is to create an obstacle to the free flow of trade, commerce, or intercourse—for example by setting an excessively high tariff wall or by prohibiting imports into or exports out of a State—such a law transcends the ordinary significance of taxation and assumes the character of a trade barrier. The Constitution‑makers intended Part XIII to abolish such barriers. The Court therefore summarized the objections to the contention that taxation is covered by the prohibition in Part XIII as follows: (1) Taxation, in its very essence, serves a public purpose; therefore it lies outside the particular restrictions that courts may characterize as reasonable and in the public interest. (2) The power to levy taxes is vested in a sovereign State to carry out government functions. The Constitution has laid the foundations of a welfare State, which expands the scope of governmental and administrative activities and consequently makes it necessary for the State to impose taxes on a much larger scale and in far‑wider fields. The legislative entries in the three Lists previously referred to empower both the Union Government and the State Governments to impose certain taxes with reference

In this case, the Court noted that if it were decided that taxation in its pure form fell within the scope of Article 301, then provisions regulating the movement of goods and passengers would become ineffective or even meaningless. The Court explained that accepting the appellants’ argument would subject many taxes, such as sales tax imposed by both the Union and the States, to the procedures prescribed in Articles 303 and 304, thereby substantially reducing the limited sovereignty of the States that the Constitution intended to preserve. The Court further observed that taxation is essentially a legislative function of the State, and making every tax law subject to constitutional challenge would render such laws constantly justiciable, compelling the State to justify each tax before the courts and thereby disrupting the division of powers on which modern constitutions, including the Indian Constitution, were founded. Additionally, the Court emphasized that taxation on the movement of goods and passengers does not automatically constitute an impediment to trade. Turning to the opposite extreme, the Court rejected the view that taxation lay wholly outside Article 301, because Article 304 explicitly referenced taxation for certain purposes and, before its repeal in 1956, Article 306 also referred to taxes or duties on inter‑State imports and exports. The Court described those imposts as barriers akin to customs duties, which Article 301 was designed to eliminate. It clarified that while Article 304 recognised a State Legislature’s power to tax goods imported from other States, it simultaneously required that a comparable tax be imposed on goods produced within the same State, thereby distinguishing revenue‑raising taxation from discriminatory taxation intended to impede free trade. The Court concluded that as long as a tax did not act as an obstacle to the free flow of goods and commodities between States, including Union territories, its validity could not be attacked on the basis of Part XIII. Nevertheless, the Court stressed that Article 304 did not grant the power to tax; rather, it merely preserved the existing power while prohibiting any tax that would impede free movement. Finally, the Court observed that Article 301, which initiates Part XIII, contains the pivotal phrase “shall be free” and that this freedom is not absolute; it does not prevent all legislation, but sets the boundary within which taxation and other statutes must operate without creating barriers to trade and commerce.

In examining the numerous entries that appear in the three Lists, it becomes evident that both Parliament and the State Legislatures have been granted authority to legislate with respect to trade, commerce and intercourse. At the same time, it is equally apparent that such legislation must not create obstacles that impede the free flow of trade and commerce. The Court observes that the freedom articulated in the pertinent constitutional provision is not an unconditional exemption from taxation relating to trade, commerce and intercourse, a point illustrated by entries 89 and 92 A in List I, entries 52, 54 and 56 to 60 in List II, and entry 35 in List III. Each of these entries expressly refers to the power to levy taxes on various aspects of trade, commerce and intercourse. Consequently, the Union as well as the State Legislatures possess the power to impose taxes that could, in effect, create trade barriers, tariff walls or imposts, which would have a harmful impact on the unrestricted movement of trade, commerce and intercourse. This constitutional freedom, however, is further limited by the authority granted to Parliament or a State Legislature to impose restrictions that serve the public interest. Moreover, Parliament has been expressly empowered to enact legislation that grants preference or allows discrimination in narrowly defined situations, as stipulated in clause (2) of Article 303. On a balanced construction of Part XIII, the following principles emerge: first, trade, commerce and intercourse throughout the territory of India are not absolutely free but may be regulated by legislation of Parliament or a State Legislature; second, the freedom proclaimed by Article 301 does not prohibit taxation per se, but forbids taxation that directly obstructs the free flow of trade, commerce and intercourse; third, Article 302 permits Parliament to impose non‑discriminatory restrictions in the public interest; fourth, Article 303(2) allows Parliament to enact discriminatory or preferential measures when dealing with emergencies such as a scarcity of goods in any part of the country; fifth, Article 304(b) authorizes State Legislatures to impose reasonable restrictions in the public interest; sixth, Article 304(a) enables State Legislatures to levy non‑discriminatory taxes on goods imported from another State, provided similar taxes are also levied on goods produced or manufactured within that State; and finally, Article 305 provides that existing restrictions may continue unless the President, by order, directs otherwise.

Having considered the various arguments for and against the proposition that Article 301 encompasses a blanket prohibition on taxation, the Court now turns to a detailed analysis of the provisions of the impugned Act. This examination is undertaken to determine, in light of the foregoing discussion, whether any specific provisions of the Act should be declared unconstitutional because they infringe upon the freedom guaranteed by Article 301, as asserted on behalf of the appellants.

In this case, the Court considered whether any provision of the Act could be struck down as unconstitutional because it infringed Article 301, as the appellants contended. The preamble of the Act disclosed that its purpose was to impose a tax on certain goods conveyed by road or inland waterways. Section 2(4) defined “Dealer” as a person who owns jute in bales before it is carried by motor vehicle, cart, trolley, boat, animal, human agency or any other means except railways or airways, and the definition expressly included the dealer’s agent. Clause (12) of Section 2 defined “Producer” as a producer of tea and also encompassed the person in charge of the garden where tea is produced. Section 3, the charging provision, stipulated that manufactured tea packed in chests and carried by motor vehicle, etc., but not by railways or airways, was liable to a tax at a specified rate per pound, and that the tax was to be collected from the producer. The same section provided that jute conveyed in bales by motor vehicle, etc., again excluding railways and airways, was liable to a tax at a specified rate per maund, and that this tax was to be collected from the dealer. The Court noted that it was unnecessary to reproduce the exact rates because no argument was raised that the rates were oppressive or excessive. The tax on manufactured tea was payable by the producer, a term that within the statute includes the garden manager, and this provision gave rise to the argument that the tax functioned as an excise duty in disguise; the Court indicated that this issue would be addressed later in the judgment. The tax on jute, on the other hand, was made payable by the dealer, meaning the person who owned the jute in bales. Section 6 identified the authorities authorized to assess and collect the tax. Section 7 required every producer and dealer to submit returns concerning the tea or jute that had become liable to tax under Section 3. Section 8 dealt with the licensing of “balers,” interpreted as persons who owned or possessed a pressing machine for compressing jute into bales. Section 9 set out the procedure for assessment, while Section 10 described the circumstances in which an assessment could be cancelled. Section 11 prescribed the procedure to be followed where assessments had escaped liability or where there was an evasion of tax. The Court observed that reference to the remaining provisions of the Act was unnecessary because they were not relevant to the arguments presented. From the concise summary of the relevant statutory provisions, the Court concluded that the Act was a pure taxing statute, showing no indication of discrimination against dealers or producers located outside the State of Assam, nor any preference for those inside the State. On its face, therefore, the

In this case the Court observed that the statute under scrutiny does not exhibit any of the defects that Part XIII of the Constitution was designed to prevent. No allegation was made that the law places an excessive burden on either dealers or producers of the commodities involved. According to the language of the Act, there is no intention to create obstacles or impediments to the free movement of jute and tea. Moreover, it would be contrary to the interests of the State of Assam to impose such barriers, since Assam is a major producer of these goods and the principal market for them lies in Calcutta. Given these facts, the Court found it difficult, if not impossible, to conclude that the Act falls within the scope of Article 301 of the Constitution. Consequently, the Court held that no further analysis of the remaining provisions of Part XIII was required. Having therefore rejected the principal ground of attack on the constitutionality of the Act based on Article 301, the Court turned to the additional submissions raised by the appellants. The appellants contended that the legislature of Assam lacked the authority to enact the statute. The Court thus examined whether the Act is covered by any entries in List II of the Seventh Schedule. It noted that Entry 56, which reads “Taxes on goods and passengers carried by rail or in inland waterways,” plainly embraces the impugned legislation. The Court saw no need to invoke the doctrine of pith and substance because the statute is a straightforward taxing measure aimed at the conveyance of goods—specifically jute and tea—by road or by inland waterway. In the Court’s view, this is a simple case of taxation squarely within the ambit of Entry 56. The appellants attempted to support their competence argument by alleging that, although the law appears to tax transport under Entry 56, in substance it amounts to an excise duty as defined in Entry 84 of List I. The Court rejected this subsidiary contention, observing that no tax is levied under the Act unless jute or tea is actually moved from one place to another, either within Assam or beyond its borders. The tax liability arises only when the goods are placed on a motor truck, boat, steamer or any other mode of conveyance contemplated by the statute. Therefore, the argument that the law is an excise duty could not be sustained. The Court also noted that a similar line of reasoning had been advanced in the earlier case of The Tata Iron & Steel Co. Ltd. v. The State of Bihar.

The Court noted that the earlier judgment reported in S.C.R. 1355 and delivered by Das, C.J., addressed the contention that the tax in the earlier case was not a tax on the sale of goods but, in substance, a duty of excise. The Court observed that this contention ignored the effect of clause (ii), which made the producer or manufacturer liable to pay the tax because he sold the goods, not because he produced them. In other words, the tax was imposed on the producer or manufacturer only in his capacity as a seller, not in his capacity as a manufacturer, as earlier explained in Boddu Paidanna’s case (1942) F.C.R. 290. The Court then quoted the Judicial Committee in Governor General v. Province of Madras, 72 I.A. 91 at p. 103, stating that “a duty of excise is primarily a duty levied on a manufacturer or producer in respect of the commodity manufactured or produced. It is a tax on goods not on sales or the proceeds of sale of goods.” The Court added that if goods produced in Bihar were destroyed by fire before being sold, the manufacturer would not be liable to any tax under section 4(1) read with section 2(g), second proviso. As Gwyer, C.J., had explained in Boddu Paidanna’s case at p. 102, the manufacturer would be liable, if at all, to a sales‑tax because he sells and not because he manufactures, and he would escape liability if he gave away everything from his factory. The Court said that these observations fully covered the present dispute. It observed that the Legislature had selected the dealer or producer as a convenient agency for collecting the tax imposed by section 3, but the trigger for the tax was the transport of the goods, not their production or dealing. Consequently, the Act should be understood as imposing a tax on goods carried by road or inland waterways.

The Court then examined another argument challenging the competence of the Assam Legislature, which claimed that the Act infringed upon the Tea Act of 1953. The petitioners argued that the tea industry was a subject within Union competence because the Tea Act declared it expedient for the Union to take control of the industry. The Tea Act, the Court noted, created a Tea Board under section 4 with functions that included regulating tea production, controlling the extent of cultivation, improving tea quality, and promoting co‑operative efforts among growers and manufacturers, as set out in section 10. Chapter III of the Tea Act provided for control over the expansion of tea cultivation, while Chapter IV dealt with control over export of tea and tea seed. The Court observed that there were no provisions in the Tea Act that conflicted with the provisions of the impugned Act, and therefore this line of attack also failed.

Chapter V of the Tea Act dealt with the control of tea export and tea seed export. The chapter provided that a customs duty should be imposed on tea that was exported from India. The revenue collected from that duty, together with any cess that was levied, was required to be credited to the Consolidated Fund of India. From this Fund, which was identified as the Tea Fund, the expenses of the establishments created by the Tea Act were to be met. The remaining provisions of the Act were intended to give effect to the main provisions of the legislation. The Court observed that none of the provisions of the Tea Act conflicted with any provision of the impugned Act. Consequently, the Court concluded that the argument challenging the Act on the basis of a conflict with the Tea Act failed.

A third line of argument was raised against the constitutionality of the Act on the ground that the legislation was extra‑territorial because it purported to tax producers and dealers who might not be residents of the State of Assam. This argument was presented on behalf of appellants and petitioners who were from West Bengal and who had to move their goods by road or by waterways that passed through Assam while travelling from one part of West Bengal to another part of the same state. The appellants contended that although their goods necessarily passed through a portion of Assam’s territory, the goods had been produced, packed and intended for transport wholly within West Bengal. The appellants acknowledged that a real and substantial nexus existed to support the taxation, but they argued that the stretch of Assam traversed by the goods was relatively small compared with the entire journey of the merchandise. The Court held that, when testing the validity of a statute on the basis of extra‑territoriality, it was irrelevant to compare the size of the territorial nexus with the total length of the journey. The Court stated that if goods belonging to, or carried by, the appellants passed through any part of Assam, the tax could not be successfully challenged on the extra‑territoriality ground, provided that the legislature had the competence to impose the tax. The Court referred to its earlier observations in The Tata Iron and Steel Co. Ltd. v. The State of Bihar ([1958] S.C.R. 1353) at pages 1369‑1371, where the Chief Justice had examined the theory of nexus in a broad body of case law. Adopting that reasoning, the Court held that the Act did not suffer from extra‑territoriality. The Court acknowledged that the incidence of the tax might fall upon persons who did not ordinarily reside in Assam or upon goods not produced in Assam, but it concluded that this fact was sufficient to sustain the tax.

In its analysis, the Court observed that the earlier discussion concerning the tax being characterized as a duty of excise applied with the same force to the present argument. The tax was described as levyable on any goods that passed through any portion of Assam’s territory during their journey. The liability did not depend on whether the owners or producers of the goods were residents of Assam; rather, it arose because a waterway or roadway situated within Assam had been used for part of the transport. From this reasoning, the Court concluded that the Act possessed no defect on the basis that it operated extra‑territorially. The Court therefore found that the claim of extra‑territoriality could not be sustained.

Turning to the final ground of attack, identified as point 27, the Court examined the allegation that the Act discriminated in violation of Article 14 of the Constitution. It was submitted that the legislation singled out tea packed in chests and jute packed in bales for taxation, while leaving the same commodities in alternative containers or in the hands of other parties free from tax. The Court explained that the Legislature had deliberately chosen to tax the transport of those commodities over land or water when they were packaged in the forms most commonly used for long‑distance carriage. Accordingly, the selection did not represent a preference for one class of goods over another class of the same kind. The purpose of the statute was to tax the conveyance of the commodities, and the Legislature was presumed to have adopted the most convenient packaging method for that purpose. No evidence had been presented to show that a substantial quantity of the goods was moved over long distances in any form other than chests or bales. Moreover, the Court held that when a Legislature decides to impose a tax, it is not obligated to tax every possible form or variety of the subject matter. The Legislature may select certain forms so as to achieve the revenue objectives it has set. It is not the role of the courts to require that all possible methods be taxed or to dictate alternative approaches. The Legislature is therefore free to impose the tax in a manner that it finds most suitable for collection and calculation. Having found that all of the attacks on the constitutionality of the Act were untenable, the Court, at point 28, ordered that the appeals and petitions be dismissed with costs. Finally, at point 29, the Court explained that it deliberately avoided citing decisions from foreign jurisdictions such as the United States or Australia, because the constitutional frameworks of those countries are not comparable to that of India, and therefore their precedents on statutory construction could not guide the resolution of the issues in this case.

The Judge observed that decisions from other jurisdictions whose statutes are phrased differently from Indian law cannot, in his view, serve as a reliable guide for resolving disputes that arise under the Indian Constitution. He expressed regret that his opinion diverged from that of the majority of the Court. He explained that his reason for dissent lay in his own reading of Part XIII of the Constitution, which, in his opinion, does not support the conclusion that a general levy of tax falls within the scope of Article 301 of the Constitution. In other words, he could not accept the inference that Article 301 automatically permits taxation of the kind contested before the Court.

The Judge then turned to the difficult question concerning the interpretation of the provisions of Part XIII of the Constitution. He noted that this question had been mentioned only incidentally in a few reported judgments of this Court, and that it now had to be examined fully in the present batch of cases. The batch comprised three appeals that had been taken to this Court on a certificate issued by the Assam High Court pursuant to Article 132, together with two separate petitions filed under Article 32. The three appellants were tea‑producing companies. Two of them – identified as Civil Appeal No. 126 of 1958 and Civil Appeal No. 128 of 1958 – operated tea plantations in the Sibsagar district of Assam. The third company – Civil Appeal No. 127 of 1958 – cultivated tea in Jalpaiguri, a district in West Bengal. All three companies, hereafter referred to as the appellants, shipped their tea to Calcutta so that it could be sold in the Calcutta market for local consumption or for export outside India. The tea grown in Jalpaiguri had to cross a short stretch of Assam’s territory, whereas the tea grown in Assam had to traverse the whole of Assam before reaching Calcutta. The Judge observed that only a very small portion of Assam’s tea was consumed within the state itself; the great majority was destined for the Calcutta market. While a considerable amount of the tea travelled by rail, a substantial quantity also moved by road or by inland waterways. Because of this, the tea became subject to the tax imposed under the Assam Taxation (on Goods Carried by Roads or Inland Waterways) Act, 1954, referred to as Act XIII of 1954. The Act had been enacted by the Assam Legislature to authorise a tax on certain goods conveyed by road or inland waterway within the state, and it received the Governor’s assent on 9 April 1954. Acting on behalf of the State of Assam – hereafter called the respondent – the state’s officers required the appellants to comply with the various obligations imposed by the Act and issued tax demands on the tea they were transporting. The appellants paid the tax demands, but only under protest. Shortly thereafter, they filed petitions before the Assam High Court under Article 226, challenging both the validity of the Act and the tax assessments made by the respondent’s officers. In each petition the appellants sought the issuance of a writ of mandamus, asking the Court to compel the respondent and its officers to refrain from enforcing the provisions of the Act against them.

The petitioners requested that the Court issue a writ directing the respondent and its officers to refrain from implementing the provisions of the Assam Taxation (on Goods Carried by Roads or Inland Waterways) Act, 1954 and from enforcing the Act against the appellants. They alternatively asked for a writ of prohibition or any other appropriate writ that would restrain the respondent and its officers from imposing the Act on the appellants. These applications placed the question of the Act’s validity before the Assam High Court for judicial examination. The appellants challenged the constitutionality of the Act on several grounds, the principal one being that the Act breached Article 301 of the Constitution and, because it failed to comply with Article 304(b), it was ultra vires. They further asserted that tea constituted a controlled industry under Act 29 of 1953, making the Union Government solely competent to regulate the manufacture, production, distribution and transport of tea; consequently, they argued that the Assam Legislature lacked the authority to enact the Act. In addition, the appellants contended that although the Act was purportedly passed under Entry 56 of List II, in substance it imposed a duty of excise, which could be legislated only under Entry 84 of List I. Finally, they claimed that the Act violated the fundamental right to equality before the law guaranteed by Article 14.

The respondent disputed each of these contentions. It submitted that the Act fell squarely within the legislative competence of the Assam Legislature under Entry 56 of List II and that the provisions of Part XIII of the Constitution were entirely inapplicable to the matter. The respondent also maintained that Article 14 had not been infringed and rejected the argument that a controlled industry could be dealt with solely by the Union Government or that the Act effectively imposed an excise duty. The petitions were heard by a Special Bench of the Assam High Court, where Chief Justice Sarjoo Prasad and Justice Ram Labhaya each delivered separate yet concurring judgments rejecting all the pleas raised by the appellants. Following the adverse judgments, the appellants obtained a certificate under Article 132 of the Constitution, thereby bringing three appeals before this Court. These appeals present for determination all the points that were argued before the High Court, with the principal issue centring on the applicability of Part XIII. The two petitions filed under Article 32 raise substantially the same question; the petitioners are tea companies engaged in the cultivation and manufacture of tea in Jalpaiguri, West Bengal, and the respondent has sought to subject them to the provisions of the Act, a move the petitioners contest as beyond the respondent’s authority to levy a tax.

The Court observed that, because the main question raised in these appeals appeared to be of great importance and might affect other States, it ordered that a notice be issued to the Attorney‑General of India as well as to the Advocates‑General of every State in the country. Accordingly, the Attorney‑General appeared before the Court, and the States of Bihar, Madras, Punjab, Rajasthan and Uttar Pradesh were also heard and gave their submissions on the matter.

The principal issue before the Court concerned the validity of the impugned Act on the ground that it violated Article 301 of the Constitution. The Court explained that this challenge inevitably required an interpretation of the relevant provisions of Part XIII, which begins with Article 301 stating that “subject to the other provisions of this Part, trade, commerce and intercourse throughout the territory of India shall be free.” The appellants argued that this provision imposes a limitation on the legislative power of both the State Legislature and the Parliament, and that the Act must be judged on that basis. They contended that the language of Article 301 is broad, clear and cannot reasonably be interpreted to exclude a taxing law that restricts trade, commerce or intercourse, whether directly or indirectly. In contrast, the respondent, the Attorney‑General, and the other States submitted that tax laws are governed separately by Part XII and that no part of Part XIII should be extended to them. As an alternative, they suggested that the provisions of Part XIII should apply only to those entries in the Seventh Schedule that deal specifically with trade, commerce and intercourse. This view would bring within the scope of Part XIII Entry 42 in List I (inter‑State trade and commerce), Entry 26 in List II (trade and commerce subject to Entry 33 in List III), and Entry 33 in List III (trade and commerce as specified). The Court noted that both positions appeared logical at first glance and possessed an appealing simplicity, but it needed to determine which contention correctly reflected the law. The Court asked whether the correct answer lay wholly with one side, or somewhere in between, and emphasized that a fair and reasonable construction of the relevant articles of Part XIII was essential before reaching a decision.

Before undertaking that construction, the Court said it was necessary to consider some general background concerning Part XIII. It recalled that, prior to the adoption of the Constitution, roughly two‑thirds of the Indian territory was under British rule and was known as British India, while the remaining one‑third consisted of princely States ruled by Indian princes. Many of those princely States claimed sovereign rights within the limits imposed by the paramount power, and exercised their legislative authority by imposing taxes on trade and commerce. This practice led to the erection of customs barriers between the princely States and the rest of the country. The Court noted that, during that period, the regulation of such barriers in British India was governed by Section 297 of the Constitution Act, 1935, a provision to which the Court would later refer. Consequently, before 1950, the free flow of trade and commerce was obstructed at various points that corresponded to the boundaries of the Indian States. After India achieved political independence in 1947 and before the Constitution came into force, the process of merging and integrating the princely States with the rest of the country proceeded rapidly. By the time the Constitution was adopted, the territories of the former princely States had largely become part of the unified Indian Union, forming the backdrop against which Part XIII was framed.

Before the Constitution came into force, a portion of the Indian sub‑continent was ruled by Indian princes and was composed of numerous princely states. Many of those states asserted sovereign authority, albeit within the constraints imposed by the paramount power, and they claimed the right to levy taxes on trade and commerce. The exercise of this fiscal authority resulted in the erection of customs barriers between the princely territories and the remainder of India. The legal framework governing such barriers in British India derived from section 297 of the Constitution Act, 1935, a provision to which the Court would later refer. Consequently, prior to 1950 the movement of trade and commerce was obstructed at several points that coincided with the boundaries of the princely states.

After India attained political freedom in 1947 and before the adoption of the Constitution, the government pursued an accelerated programme of merger and integration of the princely states with the rest of the country. By the time the Constitution was enacted, the territorial map of India comprised two categories of states: Part A states, which largely corresponded to the provinces of former British India, and Part B states, which consisted of the former princely states. This integration of the princely states into the Union of India had been preceded by earlier consolidations among the states themselves. The framers of the Constitution were fully aware of the trade barriers that had been erected by the princely states in the exercise of their legislative powers, and they incorporated Articles in Part XIII of the Constitution with the purpose of eliminating those obstacles. The principal objective of Article 301 was to guarantee the free flow of trade, commerce and intercourse throughout the entire territory of India.

In drafting the relevant provisions of Part XIII, the Constitution‑makers recognised that economic unity was indispensable for the stability and progress of the federal system established by the Constitution. While political freedom and political unity had already been achieved, the framers believed that these achievements needed to be reinforced by an accompanying economic unity. They also anticipated that, over time, different political parties with diverse economic philosophies might assume power in the various constituent units of the Union, potentially creating local and regional pressures on economic policy. Such local or regional anxieties could prompt a state legislature to adopt measures aimed solely at protecting regional interests, without sufficient regard for their impact on the national economy. Part XIII was intended to pre‑empt such a scenario. The free movement and exchange of goods across the whole of India was considered essential for the nation's economy and for maintaining and improving the country’s standards of licensing. Accordingly, Article 301 enshrined the principle that trade should be free throughout the territory of India.

In this case the Court observed that the constitutional guarantee of free commerce and intercourse is not a superficial slogan, nor a mere hopeful declaration, nor simply a statement of state policy direction; rather, it embodies a fundamental principle that the nation’s economic unity serves as the chief source of stability and progress for its political and cultural unity.

The Court noted that the significance of this principle could be better understood by referring to the observations of Justice Cardozo in C.A.F. Seelig Inc. v. Charles H. Baldwin, 294 U.S. 511, 523 (79 L. Ed. 1033, 1038), where he discussed the United States commerce clause. Justice Cardozo stated that the relevant constitutional provision was crafted under a broad political philosophy, emphasizing that the peoples of the various states must succeed or fail together, and that long‑term prosperity and salvation are found in union rather than division.

The Court further recorded that the learned Attorney General, on behalf of the States, raised another general consideration. It was argued that when interpreting the breadth of the freedom guaranteed by Article 301, one must keep in mind that expanding the scope of that freedom inevitably restricts the legislative authority of the States. The State legislatures possess plenary power to enact laws on matters enumerated in Parts II and III of the Seventh Schedule.

The Court explained that if the language of Article 301 were given the widest possible interpretation, as the appellants suggested, the States would be unable to legislate on many entries in those Lists without following the procedure mandated by Article 304(b). Imposing such a restriction on State legislative power would be unreasonable and would unduly curtail their freedom of action.

While acknowledging this argument, the Court observed that what appears to be a limitation on State powers under Article 304(b) can, from a national‑economic perspective, be viewed as a safeguard deliberately designed to protect the country’s economic unity. Consequently, the Court held that in interpreting Article 301 and determining the scope and effect of Part XIII, it must consider the impact of its decision on both State legislative competence and Parliament’s authority.

Having considered these general principles, the Court proceeded to examine whether tax laws fall entirely outside the ambit of Part XIII. In support of the contention that Part XIII does not apply to tax legislation, the learned Attorney General emphasized a particular factual assertion.

The learned Attorney‑General argued that the power to levy a tax formed an essential component of a sovereign state's authority and, consequently, that this power was not subject to judicial review. He supported this position by referring to the commentary in Cooley’s Constitutional Limitations, where the author described the power to impose taxes as “so unlimited in force and so searching in extent, that the courts scarcely venture to declare that it is subject to any restriction whatever, except such as test in the discretion of the authority which exercises it” (Cooley’s Constitutional Limitations, Vol. 2, 8th Ed., p. 986). The Attorney‑General also cited the observations of Chief Justice Marshall in McCulloch v. Maryland (4 Wheat. 316, 428 : 4 L. Ed. 579, 607), in which Marshall stated that “the power of taxing the people and their property is essential to the very existence of the government, and may be legitimately exercised on the objects to which it is applicable to the utmost extent to which the Government may choose to carry it. The only security against the abuse of this power is found in the structure of the Government itself.” Relying on this characterization of the taxing power, the Attorney‑General urged the Court to hold that Part XIII of the Constitution could not apply to any statute imposing a tax. The Court found this contention to be well‑founded. It observed that the legal source cited by the Attorney‑General was itself expressed as being subject to the relevant constitutional provisions. For example, the same author noted that the United States Constitution’s provision granting citizens of each state the privileges and immunities of citizens of the several states “will preclude any state from imposing upon the property which citizens of other states may own, or the business which they may carry on within its limits, any higher burdens by way of taxation than are imposed upon corresponding property or business of its own citizens” (p. 1016). Translating this principle to the Indian Constitution, the Court concluded that the power of taxation could not be allowed to violate the guarantee of equality before the law contained in Article 14. Accordingly, while the power to levy taxes was indispensable for the existence of government, its exercise had to be constrained by the constitutional limitations applicable to that power; the power of taxation was not beyond the scope of constitutional control.

The Court also referred to the decision in Ramjilal v. Income‑tax Officer, Mohindargarh ([1951] S.C.R. 127), where it had been held that “since there is a special provision in Article 265 of the Constitution that no tax shall be levied or collected except by authority of law, clause (1) of Article 31 must be regarded as concerned with deprivation of property otherwise than by the imposition or collection of tax, and inasmuch as the right conferred by Article 265 is not a right conferred by Part III of the Constitution, it could not be enforced under Article 32.” The Court noted that the effect of that decision was limited to confirming that protection against the imposition and collection of taxes, except by law, derived directly from Article 265 and could not be said to fall under clause (1) of Article 31. The Court warned that it would be unsafe to assume that the Ramjilal judgment was intended to be authority for the proposition that the levy of a tax by a taxing statute could, for instance, violate Article 14 of the Constitution. Having addressed that point, the Court turned to the next issue, namely whether tax laws were governed solely by Part XII of the Constitution and not by Part XIII, and examined the argument that Part XII constituted a self‑contained code providing all necessary provisions for the validity of any taxing statute.

The Court observed that the decision in Ramjilal v. Income‑tax Officer, Mohindargarh held that the protection against deprivation of property, except through the imposition or collection of tax, is governed by Article 265, and that the right created by Article 265 is not a right conferred by Part III of the Constitution; consequently it cannot be enforced under Article 32. The effect of that decision, the Court said, is limited to the proposition that protection against the levy and collection of taxes, except by authority of law, is found directly in Article 265 and is not covered by clause (1) of Article 31. The Court cautioned that it would be unsafe to treat that decision as authority for the view that the imposition of a tax by a taxing statute could, for example, violate Article 14 of the Constitution.

The Court then turned to the question of whether tax legislation is governed solely by Part XII of the Constitution or whether Part XIII also applies. It noted that some counsel argued that Part XII is a self‑contained chapter that contains all necessary provisions, and therefore the validity of any taxing statute should be examined only in reference to Part XII. Article 265 states that “no tax shall be levied or collected except by authority of law.” The Court emphasized that this article does not itself contemplate that its provisions are subject to other constitutional provisions, and consequently there would be no justification for applying Part XIII to tax statutes on that basis alone. It was further pointed out that the Constitution already provides specific restrictions and exceptions concerning taxation in Articles 274, 276, 285, 287 and 288, and that, according to that argument, one need not look beyond Part XII when dealing with tax laws.

In rejecting that line of reasoning, the Court held that it fails to recognise that Article 265 inevitably incorporates Article 245. In substance, Article 265 says that a tax may be levied only by “authority of law,” and the authority of law referred to is found in Article 245 together with the relevant legislative entries in Schedule VII. Article 245, which concerns the extent of laws made by Parliament and by State Legislatures, begins with the words “subject to the provisions of this Constitution.” Thus, the power of Parliament and State Legislatures to enact laws, including tax laws, is subject to the Constitution as a whole, bringing Part XIII into play. Consequently, the Court concluded that the argument that tax laws are governed solely by Part XII is untenable. The power to levy taxes is ultimately derived from Article 245 and is always subject to the constitutional provisions, including those contained in Part XIII. The Court then noted that the opening words of Article 301 are very…

The Court observed that Article 301 establishes a doctrine of freedom of trade, commerce and intercourse, but this freedom is not governed by the general provisions of the Constitution. It is governed only by the provisions that appear in Part XIII. Consequently, once the breadth and scope of the freedom guaranteed by Article 301 are defined, no constitutional provision outside Part XIII may alter or restrict that definition. The Court noted that this interpretation highlights the importance that the framers attached to the freedom of trade in the nation’s future. However, the Court clarified that the freedom was never intended to be unrestricted. An unlimited liberty in trade, commerce and intercourse would create economic disorder, possibly leading to confusion, chaos or even anarchy. Therefore, the freedom in Article 301 is expressly subject to the exceptions enumerated in the other Articles of Part XIII. The limitation operates only through those Articles and not through any provision elsewhere in the Constitution. For this reason, the Court held that, when read in its proper context and subject to the constraints laid down by the relevant Articles of Part XIII, Article 301 places a constitutional limitation on the legislative competence of both Parliament and the State Legislatures. The Court added that determining which entries in the legislative lists fall within the ambit of Article 301 depends on the actual content of the guaranteed freedom. Nevertheless, any conclusion that Article 301 applies to a particular legislature must be assessed against the provisions of Part XIII, a position the Court considered unavoidable.

The respondent’s counsel suggested that the scope and extent of Article 301 should be interpreted in light of section 297 of the Constitution Act, 1935. Section 297(1) states: “No Provincial Legislature or Government shall – (a) by virtue of the entry in the Provincial Legislature List relating to trade and commerce within the Province, or the entry in that List relating to the production, supply, and distribution of commodities, have power to pass any law or take any executive action prohibiting or restricting the entry into, or export from the Province of goods of any class or description; or (b) by virtue of anything in this Act have power to impose any tax, case, toll, or due which, as between goods manufactured or produced in the province and similar goods not so manufactured or produced, discriminates in favour of the former, or which, in the case of goods manufactured or produced outside the Province, discriminates between goods manufactured or produced in one locality and similar goods manufactured or produced in another locality.” Section 297(2) further provides that any law enacted in contravention of this provision shall be invalid. The Court noted this citation to illustrate the historical background and to assess whether the principles embodied in the earlier statute inform the contemporary application of Article 301.

In this case the Court explained that the prohibition set out in section 297 of the Constitution Act of 1935 applied only to provincial legislatures and provincial governments. It did not bind the Central Government or the Central Legislature. The Court noted that the prohibition related to entries in the provincial legislature list concerning trade and commerce, as well as the production, supply and distribution of commodities. The provision also covered bans or restrictions on the import of goods into a province or their export from a province, and it forbade discrimination against goods manufactured or produced outside the province or against goods produced in different localities. The argument presented before the Court was that when Article 301 of the Constitution was adopted, the drafters had section 297 in mind and intended only a substantial change: to extend the principles expressed in that section to the Union Government and the Union Parliament and to apply them to the territory that later became part of India, as indicated by the relevant constitutional articles. According to the argument, the essential content of the freedom of trade and commerce prescribed by section 297 remained unchanged, even though its scope was broadened to include the Union.

The Court considered the reliance placed on the observations of Justice Venkatarama Aiyar in the case of M.P.V. Sundararamier & Co. v. The States of Andhra Pradesh ([1958] S.C.R. 1422, 1483‑84). In that case the validity of certain provisions of the Sales Tax Laws Validation Act 1956 (7 of 1956) was challenged on several grounds. While addressing one of the challenges, Justice Venkatarama Aiyar, delivering the majority judgment, examined Entry 42 in List I. It had been urged that this entry should be interpreted liberally to include the power to tax, with reliance on American and Australian decisions. The Court rejected that argument, holding that Entry 42 in List I does not include taxation. In reaching that conclusion, the learned judge made general observations that it is not always safe to rely on American or Australian decisions when interpreting the Constitution of India. He stated, “the threads of our Constitution were no doubt taken from other Federal Constitution but when they were woven into the fabric of our Constitution their reach and their complexion underwent changes. Therefore, valuable as the American decisions are as showing how the question is dealt with in sister Federal Constitution great care should be taken in applying them in the interpretation of our Constitution.” He made a similar comment regarding section 92 of the Commonwealth of Australia Constitution Act and the decisions thereunder, observing: “We should also and that Art. 304(a) of the Constitution cannot be interpreted as throwing any light on the scope.” The Court noted that these observations were made in the context of interpreting section 297(1)(b) of the Government of India Act, 1935, and that the judge held the content of that section could not be enlarged by reference to Article 304(a). The Court further observed that the question of construing Article 301 with respect to taxation was not argued before it.

The Court examined whether Article 301 could be interpreted to include taxation, noting that it merely reproduces section 297(1)(b) of the Government of India Act, 1935. The Act contains no provision that corresponds to Article 301, and the learned Attorney‑General relied on the earlier judge’s observations regarding this point. The earlier judge had held that the content of section 297(1)(b) could not be enlarged by reference to Article 304(a). Although those remarks suggested that Article 304(a) did not shed light on the tax aspect of Article 301, the Court noted that this issue had not been properly argued before it. The Court respectfully pointed out that, in the earlier judge’s own language, the wide wording of Article 301 and the broader reach of Article 304(a) indicate that the latter is wider than section 297(1)(b). It further noted that, as a result, Article 304(a) indeed encompasses the matters of taxation within its scope. Turning to the argument that section 297 of the 1935 Constitution Act should solely determine the scope of Article 301, the Court expressed reluctance to accept that assumption. It held that the framers did not intend merely to extend the application of section 297 to the Union Government and Parliament. The Court observed that the drafters were aware of similar provisions in other federal constitutions, including the judicial history of section 92 of the Australian Constitution. It also noted the development of the commerce clauses in the United States Constitution as part of the framers’ considerations. The Court further hesitated to accept a view that the Constitution‑makers did not wish to enlarge the freedom guaranteed by section 297, recognizing that they envisioned a new era for India. It noted that the drafters were fully conscious of the need to maintain economic unity and to ensure that the federal structure would function smoothly and harmoniously. Consequently, the Court held that the unambiguous wording of Article 301 was intended to make the guarantee of freedom of trade, commerce and intercourse richer and wider than the guarantee provided by section 297. The precise extent of that richness and width, the Court said, must be determined by a fair and reasonable construction.

The Court examined Article 301 together with the other articles that constitute Part XIII of the Constitution. It held that the contention that tax statutes lie outside the ambit of Part XIII could not be sustained. The next issue addressed was whether the operation of Article 301 was limited only to the entries that had already been enumerated for trade and commerce. To answer this, the Court found it necessary first to analyse the overall scheme of Part XIII and to interpret the relevant articles contained therein. The Court observed that Article 301 is applicable not merely to inter‑State trade, commerce and intercourse but also to intra‑State trade, commerce and intercourse. The expression “throughout the territory of India” was interpreted to mean that the freedom guaranteed to trade and commerce must also extend to movement of goods within the same State. This view was reinforced by reference to Articles 302 and 304(b). While the concept of trade, commerce and intercourse is expansive, the present case concerned only trade, and therefore commerce and intercourse were excluded from further consideration. The Court noted that it was unnecessary to define the exact meaning of trade because it was undisputed that the appellants were engaged in trade and that the transport of goods from one place to another is an essential and integral component of trade. In a narrow sense, trade includes all activities related to buying, selling, and the exchange of commodities, and the movement of goods from place to place forms the very essence of such activities. When Article 301 speaks of the freedom of trade, the Court said it must inquire what “freedom” entails – specifically, freedom from what? The Court concluded that the freedom of trade guaranteed by Article 301 means freedom from every restriction except those expressly permitted by the other provisions of Part XIII. Although the precise scope of those permissible restrictions could raise broader issues, the Court limited its decision to the aspect arising from the provision under scrutiny. The Court stressed that constitutional questions should be addressed narrowly, avoiding unnecessary wide‑ranged inquiries, and that judgments should be confined as far as reasonably possible to the specific controversy presented by the parties. Accordingly, the Court indicated it would return to Article 301 after completing its examination of the remaining articles of Part XIII.

Article 302 was then considered. That article confers upon Parliament the authority to impose restrictions on trade, commerce and intercourse. It provides that Parliament may, by law, impose such restrictions on the freedom of trade, commerce or intercourse between one State and another or within any part of the territory of India, whenever such restrictions are deemed necessary in the public interest. The Court pointed out that the reference to a restriction on the freedom of trade “within any part of the territory of India” as distinct from freedom of trade “between one State and another” clearly demonstrates that the freedom protected by Article 301 embraces both inter‑State and intra‑State trade. Consequently, Article 302 creates an exception to the general rule established by Article 301, allowing Parliament to limit the freedom of trade when a restriction is required for the public interest. This exception ensures that the broad guarantee of freedom under Article 301 is subject to the narrowly defined qualifications set out in Article 302.

Article 302 authorises Parliament to impose restrictions on trade, commerce or intercourse within any part of the territory of India whenever such restrictions are required in the public interest. The provision expressly distinguishes a restriction on the freedom of trade within the territory of India from a restriction on trade between one State and another. This distinction makes clear that the freedom guaranteed by Article 301 embraces not only inter‑State trade but also intra‑State trade. Consequently, Article 302 functions as an exception to the general rule laid down in Article 301, allowing Parliament to curtail the freedom of trade when it is necessary for the public interest, thereby qualifying the broad guarantee of freedom in Article 301 with the limitation set out in Article 302.

Article 303 then follows. Sub‑section (1) of Article 303 states: “Notwithstanding anything in article 302, neither Parliament nor the Legislature of a State shall have power to make any law giving, or authorising the giving of, any preference to one State over another, or making, or authorising the making of, any discrimination between one State and another, by virtue of any entry relating to trade and commerce in any of the Lists in the Seventh Schedule.” Sub‑section (2) adds: “Nothing in clause (1) shall prevent Parliament from making any law giving, or authorising the giving of, any preference or making, or authorising the making of, any discrimination if it is declared by such law that it is necessary to do so for the purpose of dealing with a situation arising from scarcity of goods in any part of the territory of India.” The first part of this article operates as a proviso to Article 302, as indicated by the non‑obstante clause, which bars Parliament from enacting any law that confers a preference on one State over another or creates discrimination between States in respect of the specified entries. In other words, for the entries mentioned, the power to impose restrictions cannot be exercised to favour one State over another or to discriminate in that manner. Although the reference to the State Legislature appears contradictory to the non‑obstante clause, its inclusion underscores that, like Parliament, a State Legislature is likewise prohibited from granting preferences or enacting discriminatory measures. Sub‑article (2) constitutes an exception to sub‑article (1) of Article 303. It permits Parliament to enact a law that confers a preference or authorises discrimination, but only when Parliament itself declares, through that law, that such a measure is necessary to address a scarcity of goods affecting any part of the territory of India.

In the Court’s view, the authority to enact a law that creates discrimination or grants preference was reserved for the Parliament only when it faced an emergency resulting from a shortage of goods in some part of India. In such circumstances, Parliament could be authorised to pass legislation that gave preferential treatment to the region experiencing the scarcity.

The states, relying heavily on the observation that Article 303(1) expressly mentions the entries relating to trade and commerce in the Seventh Schedule, argued that this reference clearly defined the scope of Article 301 itself. While the Court recognised that this contention possessed some merit, it declined to hold that the reference to those entries should control the construction of Article 301. The Court explained that the context in which the entries are mentioned determines the reach of the prohibition contained in Article 303(1), but that context cannot be used to define the breadth of Article 301. Moreover, Article 303(1) does not speak of “inter‑course” outside its own sphere. The Court inferred that, having empowered Parliament to impose restrictions under Article 302, the Constitution expressly barred the use of that power for the purpose of granting preference with respect to the specified entries. It also considered that the primary aim of limiting Article 303(1) to those entries might have been to place a corresponding restriction on Parliament’s power to discriminate under Article 302. Nevertheless, the Court held that the limitation introduced by Article 303(1) could not narrow the scope of Article 301 nor alter its construction. The Court further noted that other provisions within this part of the Constitution indicate that tax laws fall within the ambit of Article 301; consequently, the reference to the entries in Article 303(1) could not restrict the application of Article 301 solely to those entries.

Article 304 was then set out as follows: “Notwithstanding anything in article 301 or article 303, the Legislature of a State may by law – (a) impose on goods imported from other States or the Union territories any tax to which similar goods manufactured or produced in that State are subject, so, however, as not to discriminate between goods so imported any goods so manufactured or produced; and (b) impose such reasonable restrictions on the freedom of trade, commerce or intercourse with or within that State may be required in the public interest: Provided that no Bill or amendment for the purposes of clause (b) shall be introduced or moved in the Legislature of State without the previous sanction of the President.” The Court explained that the effect of clause (a) of Article 304 is to treat goods imported from other states on the same basis as goods manufactured or produced within the importing state, and that it authorises the State to levy a tax on such imported goods in the same manner and to the same extent as it levies tax on goods produced internally.

Article 304(a) permits a State Legislature to levy a tax on imported goods in exactly the same manner and to the same extent as it may levy a tax on goods that are manufactured or produced within the State. The provision assumes that the State already possesses the power to tax goods that originate inside its territory, a power that is expressly provided by Article 304(b). Consequently, Article 304(a) ensures that imported goods cannot be subjected to a harsher tax treatment than comparable locally produced goods. The non‑obstante clause that refers to Article 301 operates together with Article 304(a); this indicates that, absent Article 304(a), the State would not have been permitted to impose such a tax. In effect, Article 304(a) constitutes a further exception to the freedom of trade guaranteed by Article 301, thereby helping to delineate the scope and breadth of that constitutional guarantee.

Article 304(b) further empowers a State Legislature to impose reasonable restrictions on the freedom of trade, whether that trade is with other States or within the State’s own territory. The reference to “within the State” supports the conclusion that Article 301 covers both inter‑State and intra‑State movement of goods. Article 304(b) must be read together with the non‑obstante clause that references both Article 301 and Article 303, and it confers on the State a power akin to the power granted to Parliament by Article 302. The inclusion of Article 303 in the non‑obstante clause reflects a precaution, because Article 303(1) already envisages the involvement of State Legislatures. Nevertheless, clear differences remain between the authorities of Parliament and those of State Legislatures. Notably, any Bill that a State wishes to introduce under Article 304(b) cannot be moved in the Legislature without first obtaining the President’s prior sanction. This safeguard is intended to ensure that regional economic pressures that might motivate such legislation are examined in light of the national economy’s interests. Moreover, the legislation must satisfy two additional requirements: it must be passed in the public interest, a condition that parallels the public‑interest requirement in Article 302, and the restrictions it imposes must be reasonable. Thus, three conditions must be fulfilled before a State can enact a law under Article 304(b): prior presidential sanction, a public‑interest purpose, and the reasonableness of the imposed restrictions. If the President’s sanction is not obtained, any defect may be remedied by following the procedure authorized under Article 255. Reading Articles 304(a) and 304(b) together leads to the conclusion that a State may levy taxes on goods that are manufactured, produced, or imported within its territory, and may also impose reasonable restrictions on the freedom of trade either with another State or between different areas within the same State.

The Court observed that tax legislation authorised by a State must be treated as falling within the ambit of Article 301, because the presence of a non‑obstante clause clearly indicates that such legislation is intended to be included in the freedom of trade guaranteed by that article. Article 305, which preserves existing laws and statutes establishing State monopolies, was deemed unnecessary to analyse in detail; its purpose, the Court noted, was merely to avoid disturbing the operation of pre‑existing statutes, except where the President might issue a contrary order. The Court then turned to Article 306, reproducing its full text. Article 306 provides that, notwithstanding any other provision in the same Part or elsewhere in the Constitution, any State listed in Part B of the First Schedule that, prior to the commencement of the Constitution, imposed a tax or duty on the import of goods from other States or on the export of goods to other States, may continue to levy and collect such tax or duty if an agreement has been concluded between the Government of India and the Government of that State. Such an agreement may be valid for a period not exceeding ten years from the Constitution’s commencement, and the President may, after five years, terminate or modify the agreement based on the Finance Commission’s report under Article 280. The Court pointed out that Article 306 was later omitted by Section 29 and the Schedule to the Constitution (Seventh Amendment) Act, 1956, but that its original inclusion in Part XIII clarifies the reach of Article 301. In the absence of Article 306, statutes imposing taxes or duties on imports and exports would have fallen within the operation of Article 301, because Article 306 expressly saved those pre‑existing State taxes from being invalidated by Article 301.

Returning to Article 301, the Court examined the breadth and intensity of its scope. By analysing the provisions of Part XIII in their entirety and by considering the principle of economic unity that these provisions aim to protect, the Court concluded that the freedom guaranteed by Article 301 is broader than the freedom contemplated in Section 297 of the Constitution Act of 1935. The Court affirmed that, irrespective of any additional elements that might be included, Article 301 certainly embraces the movement of trade, which is an essential and integral component of all commercial activity. Consequently, if the transportation or movement of goods were taxed solely on the basis of the manner in which the goods are carried or transported, such a tax would directly infringe the freedom of trade envisioned by Article 301. The Court emphasized that allowing taxation to impede, obstruct, or hamper the movement, transport, or carriage of goods without satisfying the conditions laid down in Part XIII would render the freedom of trade promised by Article 301 illusory. Accordingly, when Article 301 declares that trade shall be free throughout the territory of India, its primary concern is the freedom of movement that is part of trade, subject, of course, to the limitations and exceptions specified in the other Articles of Part XIII. The Court concluded that the intrinsic evidence provided by several Articles of Part XIII demonstrates that taxing laws are not excluded from the operation of Article 301; therefore, tax statutes can and do affect the freedom of trade within the constitutional framework.

In the judgment the Court observed that when taxation was imposed on the basis that goods were being carried or transported, such a tax directly interfered with the freedom of trade guaranteed by Art. 301. The Court explained that if the movement, transport or carriage of goods were permitted to be impeded, obstructed or hampered by a tax that did not meet the conditions laid down in Part XIII, the freedom of trade, which Art. 301 stresses so strongly, would become merely an illusion. The Court noted that Art. 301 declares that trade shall be free throughout the territory of India, and that the provision primarily contemplates the movement aspect of trade. Consequently, the movement or transport of trade must remain free, subject, of course, to the limitations and exceptions enumerated in the other Articles of Part XIII. The Court therefore read Art. 301 together with the remaining provisions of Part XIII and concluded that this reading yielded the result described above.

The Court further pointed out that the internal evidence contained in several Articles of Part XIII demonstrated that taxing statutes were not excluded from the operation of Art. 301. This meant that tax statutes could and did amount to restrictions on the freedom that Part XIII guarantees to trade. The Court asked whether this implication required that every tax law fall within the ambit of Part XIII, irrespective of whether its impact on trade or its movement was direct, immediate, indirect or remote. It answered that the very broad, somewhat vague and indefinite wording of Art. 301 made the task of construing its exact scope a complex and difficult problem. Nevertheless, the Court stressed that constitutional provisions must not be read in isolation; they must be read “not in vacuo but as occurring in a single complex instrument in which one part may throw light on another,” quoting the authority in James v. Commonwealth of Australia ((1936) A.C. 578, 613). Accordingly, the Court said that Art. 301 must be interpreted in light of the general scheme of the Constitution as well as of the specific provisions dealing with taxation.

In addition, the Court warned that the construction of Art. 301 should not be based on purely academic or doctrinaire considerations. Instead, a realistic approach was required, one that respected the essential features of the separation of powers upon which the federal Constitution rested. The Court reminded that Art. 301 imposed a constitutional limitation on the power of Parliament and State Legislatures to levy taxes, and that, absent such limitation, the power to tax would ordinarily be presumed to serve the public good and would not be subject to judicial review. Taking all these factors into account, the Court concluded that it was reasonable and proper to hold that the restrictions from which Art. 301 guaranteed freedom were those that directly and immediately restricted or impeded the free

The Court observed that while taxes can function as restrictions, only those taxes that directly and immediately impede the flow or movement of trade fall within the ambit of Article 301. The Court rejected the proposition that every tax, irrespective of its effect on trade, must be governed by Article 301, describing such an approach as overly extreme and untenable. Acceptance of that argument would, for example, bring a statute fixing minimum wages for industrial workers within Part XIII, merely because the resulting increase in wage outgoings might indirectly influence trade or commerce. Consequently, the Court articulated a practical test to determine the scope of the freedom guaranteed by Article 301: does the impugned restriction operate directly or immediately upon trade or its movement? This test would be applied to assess the validity of the statute presently before the Court. The Court further held that it was neither necessary nor expedient to contemplate the impact of this interpretation on other statutes or to speculate which other legislative entries might fall under Part XIII. The decision would be confined to the specific Act under scrutiny; should any other statutes be challenged, their validity would have to be examined in light of the provisions applicable to those statutes. In its conclusion, the Court explained that Article 301’s guarantee that trade shall be free throughout the territory of India means that the flow of trade must proceed smoothly and without obstruction, whether at state boundaries or at any point within a state. The protection intended is that of the free movement or transport of goods from one part of the country to another. Any enactment that imposes a direct restriction on the actual movement of such goods triggers the provisions of Article 301 and can be sustained only if it satisfies the requirements laid down in Article 302 or Article 304 of Part XIII. The Court reiterated that when it is said that the freedom of movement of trade cannot be subjected to any tax‑based restriction on the carriage of goods or their movement, the meaning is that such restrictions may be imposed by State Legislatures only after complying with Article 304(b). This does not imply that no restrictions whatsoever may be placed on the free movement of trade. The Court also noted, incidentally, that the apparent difference between the provisions of Article 302 and Article 304(b) prima facie suggests that where Parliament exercises its power under Article 302 and enacts a law imposing restrictions on

In discussing the constitutional limits on the freedom of trade, the Court observed that when Parliament enacts a law that restricts trade in the public interest, the question of whether the law itself serves the public interest may not be subject to judicial review. Under Article 302, Parliament alone possesses the authority to determine which restrictions may be imposed for public welfare, and such a determination is insulated from judicial scrutiny. Conversely, Article 304(b) imposes a dual condition on any law enacted by a State Legislature: the law must first be shown to pursue a public‑interest objective and must also have obtained prior approval from the President. Moreover, the restrictions introduced by the State law must be reasonable. The Court noted that the requirement of a public‑interest justification is generally non‑justiciable, and the President’s prior sanction is treated as evidence that this requirement has been satisfied. However, the reasonableness of the specific restrictions is a matter that courts can examine, meaning that State legislation may sometimes be challenged on that ground. The Court clarified that while this distinction between parliamentary and State powers is significant, it does not need to be resolved in the present case, and therefore the Court refrained from expressing any definitive view on the justiciability of the public‑interest requirement or the reasonableness test.

Turning to the substantive provisions of the Assam Act under consideration, the Court set out the operative clauses of the statute. The Act was enacted to impose a tax on particular goods that are transported by road or inland waterways within the State of Assam. Section 2(11) defines “producer” to include any tea producer and also the individual who manages the garden where the tea is produced. Section 3, the charging provision, stipulates that manufactured tea packed in chests and conveyed by motor vehicles, other than by rail or air, is liable to a tax calculated at a specified rate per pound, and that this tax must be collected from the producer. Parallel provisions concerning jute are also contained in the Act, though they are not relevant to the current dispute. Section 6 outlines the powers and duties of the taxing authorities, while Section 7 requires each producer to file returns detailing the manufactured tea carried in tea chests, using a form and to an authority prescribed by the legislature. Section 8 deals with the licensing of balers, defined as persons who own or operate machines that compress jute into bales. Section 9 prescribes the procedure for levying assessments, and Section 10 provides for the cancellation of assessments in specified circumstances. Section 11 addresses assessments in cases of tax evasion or escape, Section 12 permits rectification of assessments, and Section 13 imposes penalties for failure to submit returns or for tax evasion. Further, Section 19 mandates the issuance of a notice of demand, and Section 20 specifies the point at which the tax becomes payable. The Act was passed by the Assam Legislature under Entry 56 of List II, indicating that it is intended as a tax on goods moved by road or inland waterways. The Court observed that the clear purpose and object of the Act is to raise revenue by taxing goods solely on the basis that they are conveyed within the State’s territory by road or water, thereby imposing a restriction on the free movement of those goods.

In this case the Court observed that the limitation imposed by the State legislation on the free movement of goods is plainly evident on the face of the statute. It was recognised that one possible purpose for enacting the law might have been to enable the State Government to generate revenue for the repair and maintenance of its roads and waterways. However, the Court noted that the same fiscal objective could be achieved through a different legislative scheme, and that if the State intended to raise money by levying a tax on the carriage of goods, such a tax could be validly imposed only if the law satisfied the requirements laid down in Article 304 (b) of the Constitution.

The Court then stated that it was common ground that, before the bill was introduced in the State Legislature, the requisite previous sanction of the President had not been obtained, and that this deficiency had not been cured by invoking Article 255 of the Constitution. Because of this procedural defect, the Court expressed that it could not see how the validity of the tax could be sustained. In the Court’s opinion, the High Court had erred by giving an unduly restricted meaning to the relevant words of Article 301. The narrow construction adopted by the High Court, the Court said, was at least partly, if not wholly, influenced by a concern about the inevitable consequences that might follow from a broader construction of Article 301. The Court further clarified that it did not intend to express any opinion on the possible consequences of the view it was adopting in the present proceedings.

The matter before the Court involved a statute passed by the State Legislature that imposed a restriction in the form of a tax on the carriage or movement of goods. The Court held that such a restriction could be imposed by the State Legislature only if the statute had been enacted in the manner prescribed by Article 304 (b). The Court then examined the question from another perspective. It noted that when a State Legislature enacts a law under Entry 56 of List II, the basic legislative competence of the State is not contested; the dispute concerns whether that competence is limited by the provisions of Part XIII of the Constitution.

The Court explained that the purpose of the law made under Entry 56 is to place a restraint, in the form of a tax, on the movement of trade. If the movement of trade is considered an integral component of trade itself, the statute in substance places a restriction directly on trade. The effect of the statute on the movement of trade is direct and immediate, not indirect or remote. Consequently, legislation enacted under Entry 56 must be regarded as falling squarely within Article 301 as legislation concerning trade and commerce. The Court further referred to earlier decisions of this Court in which the validity of statutes was examined by asking whether the impugned law directly relates to the subject matter covered by a specific constitutional article. The Court noted that this “directness” test had been applied, for example, by Chief Justice Kania in earlier jurisprudence.

In earlier judgments the Court examined the test for determining whether legislation fell within the field of trade and commerce. The test was first articulated in the decision of A. K. Gopalan v. The State of Madras ([1950] S.C.R. 88) and was subsequently adopted in Ram Singh v. The State of Delhi ([1951] S.C.R. 451). Although the issues in those cases primarily concerned the fundamental rights guaranteed by Articles 19, 21 and 22, the present reference to those decisions is intended to illustrate that the same test would require the present Act to be declared invalid. According to Kania, C.J., the proper approach is to examine only the directness of the legislation. Applying that principle, it is evident that the Act imposes a tax on the carriage of goods; such a tax directly falls within the scope of Part XIII of the Constitution.

During the arguments, the learned Attorney‑General urged the Court to apply the test of “pith and substance” and argued that, if that test were applied, the Act could be sustained as valid. To support this contention, the Attorney‑General relied on observations made by Das, C.J. in The State of Bombay v. R. M. D. Chamarbaugwala ([1957] S.C.R. 874). In that case the Court was asked to consider the validity of the Bombay Lotteries and Prize Competitions Control and Tax (Amendment) Act, 1952. The challenge to that Act was premised on two grounds: first, that it infringed the fundamental right guaranteed under Article 19(1)(g); and second, that it contravened the provisions of Article 301. The Court rejected the first ground by holding that gambling could not be classified as trade or business within the meaning of Article 19(1)(g). That determination automatically negated the second ground because, if gambling was not trade or business under Article 19(1)(g), it could not be deemed trade or commerce under Article 301. The Court’s conclusion that gambling is not a trade made the position self‑evident.

Nevertheless, the learned Chief Justice also applied the “pith and substance” test incidentally and observed that the impugned legislation was, in substance, an enactment dealing with betting and gambling. Since betting or gambling was not regarded as trade, commerce or business, the Chief Justice stated that “the validity of the Act had not to be decided by the yardstick of reasonableness and public interest laid down in Articles 19(6) and 304”. In this connection it is appropriate to note that the quotation attributed to Lord Porter from Commonwealth of Australia & Ors. v. Bank of New South Wales ([1950] S.C.R. 88) has not been reproduced accurately. In fact, when referring to the phrase “pith and substance”, Lord Porter observed that “they no doubt raise in convenient form an appropriate question in cases where the real issue is one”.

Lord Porter explained that the expression “pith and substance” is useful when the real issue is whether a statute falls within the permitted legislative field. He noted that the test helps determine whether a law that interferes with trade, commerce or intercourse among the States is nevertheless beyond the operation of section 92 because it is essentially regulatory in character (pages 312‑313). These comments suggest that the pith‑and‑substance test is most appropriately employed in disputes concerning the legislative competence of a legislature and must be resolved by looking at the entries to which the impugned law can be related. When two entries in the legislative lists conflict, and a law would be competent under one entry but not under the other, the doctrine of pith and substance is invoked to discover the true nature and character of the legislation. The Court referred to the authorities in Prafulla Kumar Mukherjee v. Bank of Commerce Ltd., Khulna ((1947) L.R. 74 I.A. 23) and Subrahmanyan Chettiar v. Muttuswami Goundan ([1940] F.C.R. 188) for this principle. Applying the test to the present case, however, leads to the same conclusion: the essential character of the statute is the taxation of the carriage of goods, and that falls squarely within the scope of Article 301.

At the beginning of the judgment, the Court observed that the problem before it was complex and had been mentioned in several earlier decisions. In State of Bombay v. The United Motors (India) Ltd. ([1953] S.C.R. 1069), Chief Justice Patanjali Sastri observed that the freedom of inter‑State trade and commerce guaranteed by Article 301 is expressly subordinate to a State’s power to tax goods imported from sister States, provided the tax is non‑discriminatory. The Chief Justice explained that the commercial unity of India yields to a State’s authority to impose a non‑discriminatory tax on such imports, suggesting that Article 304(a) and (b) concern taxes and therefore contradict the argument that tax legislation lies outside Part XIII. A later decision, Saghir Ahmed v. State of U.P., dealt with the unconstitutionality of provisions of the U.P. Road Transport Act, 1951 on grounds unrelated to Part XIII, yet Justice Mukherjea, speaking for the Court, acknowledged that the issues raised by Part XIII were “not quite free from difficulty.” This observation highlighted the nuanced relationship between the constitutional provisions on trade, commerce and taxation.

The Court observed that counsel had presented arguments regarding the advantages and disadvantages of Article 301. One of the principal points raised was that Article 301 furnishes protection for the conduct of trade in its entirety, distinct from the constitutional guarantee afforded to an individual to engage in trade. In other words, the provision was understood to regulate the movement of goods or persons across State boundaries, whether the movement occurs within a State or crosses State frontiers, and it does not directly address the personal right of an individual to carry on a trade or commerce. According to the submissions, the individual right to trade was covered by Article 19(1)(g), and therefore the two Articles were said to have been enacted for different purposes. The Court noted that similar observations had been made by Chief Justice Das in the decision of R. M. D. Chamarbaugwala ( [1957] S.C.R. 874). The Court further stated that it was unnecessary on the present occasion to decide whether the fields covered by Article 19(1)(g) and Article 301 can be separated in the manner suggested by those observations. It mentioned that one might argue that trade, regarded as a whole, inevitably relies on human agents, and consequently protection granted to trade could extend to protection of the individuals who conduct that trade. In that sense, the two freedoms could overlap. However, the Court expressly declined to pursue this line of reasoning any further in the present proceedings.

Before concluding, the Court referred to two decisions that examined the scope and effect of section 92 of the Australian Constitution. The Court explained that it had deliberately avoided mentioning these decisions earlier because it seemed unreasonable to rely on that section or the associated case law for construing the relevant Articles of Part XIII of the Indian Constitution. The Court acknowledged that the political and historical background of the Australian federal system, the wording of its Constitution, the distribution of powers, and the overall constitutional scheme differ from those of India, and therefore it would be prudent to exercise caution when seeking guidance from Australian judgments in interpreting Indian constitutional provisions. In this regard, the Court recalled a warning expressed by Justice Venkatarama Aiyar against indiscriminate reliance on Australian and American decisions, a caution that had been articulated earlier in the case of M. P. V. Sundararamier & Co. The same caution had been voiced by Chief Justice Gwyer in 1939, when he observed in The Central Provinces and Berar Sales of Motor Spirit and Lubricants Taxation Act, 1938 (A.I.R. 1939 F.C. 1, 5) that “there are few subjects on which the decisions of other Courts require to be treated with greater caution than that of federal and provincial powers, for in the last analysis the decision must depend upon the words of the Constitution which the Court is interpreting; and since no two Constitutions are in identical terms it is extremely risky to assume that a decision on one … can be applied without qualification to another.” The Court emphasized that even where the words appear identical, their meaning may be coloured by context and may therefore differ. Nonetheless, the Court noted that previous judgments of this Court have frequently referred to Australian and American decisions when dealing with constitutional questions, illustrating the characteristic practice of the judiciary. Consequently, when faced with a provision that is not entirely clear, the Court felt it appropriate to examine how other judicial authorities have addressed comparable provisions, and it indicated that it would therefore refer to two Privy Council decisions concerning the construction of section 92 of the Australian Constitution.

In this passage the Court noted that even when the wording of constitutional provisions is identical, a term may acquire different meaning depending on its context, so one cannot automatically apply a rule from one constitution to another. The Court observed that despite this caution, decisions of this Court have frequently cited Australian and American cases when confronting constitutional questions, reflecting a usual feature of judicial reasoning. When a constitutional provision is ambiguous, judges often look to how other courts have interpreted similar provisions in sister constitutions. Accordingly, the Court intended to examine two Privy Council cases concerning section 92 of the Australian Constitution. Section 92 begins with the clause, described by Lord Porter as a “labyrinth where there is no golden thread,” and provides that “On the imposition of uniform duties of customs, trade, commerce, and intercourse among the States, whether by means of internal carriage or ocean navigation, shall be absolutely free.” The role of Frederick Alexander James, a trader in dried fruits, in obtaining authoritative judgments on the true meaning of that clause is well‑known. James contested legislative interference in three separate suits and succeeded each time. In James v. State of South Australia ((1927) 40 C.L.R. 1) the Court struck down section 20 of the Dried Fruits Export Control Act, 1924. In James v. Cowan ((1932) A.C. 542) section 28 was challenged, and in James v. Commonwealth of Australia ((1936) A.C. 578, 613) James sought a declaration that the Dried Fruits Acts of 1928 and 1935 and the regulations made under them were invalid because they contravened section 92. The present discussion turns to the observations of the Privy Council in that last case. Lord Wright, speaking for the Council, said that the word “free” in section 92 is inherently vague and must be given meaning by reference to its context. He noted that the ordinary understanding of “free trade” is freedom from tariffs, but added that the term “free” in section 92 cannot be confined to that narrow sense. The Council held that every step in a commercial transaction constitutes an act of trade, and that any State regulation of any of those steps interferes with the freedom of trade guaranteed by the provision. The Council also remarked that little assistance is obtained by suggesting that trade may remain “free” even though the trader must pay for ancillary costs such as tolls or railway rates.

In the earlier discussion the Court observed that requiring a trader to pay for various services such as tolls, railway rates and similar charges could, in effect, hinder the freedom of trade guaranteed by section 92 of the Constitution. The Court explained that although a trader may still be able to trade despite having to meet these charges, the imposition of such fees may nonetheless constitute a restriction on the freedom of trade contemplated by that constitutional provision. Consequently, the Court concluded that a tax of this nature could be regarded as a restriction within the meaning of article 301.

The Court then turned to the decision in Commonwealth of Australia v. Bank of New South Wales (1927) 40 C.L.R. 1, a case previously cited in relation to the “pith and substance” test. In that case the Privy Council examined the validity of section 46 of the Banking Act (Commonwealth) No 57 of 1947 against the backdrop of section 92 of the Australian Constitution. Lord Porter formulated a test by asking whether the legislation “directly restricts the inter‑state business of banking”, noting that the test would later be refined to consider incidental effects. He articulated two general propositions: first, that regulation of trade, commerce and intercourse among the States is compatible with the principle of absolute freedom; and second, that section 92 is breached only when a legislative or executive measure operates to restrict such trade, commerce or intercourse directly and immediately, as opposed to creating a remote or indirect impediment. The Court held that this precedent supports its own conclusion regarding the scope and effect of article 301.

Applying the foregoing reasoning, the Court held that the Assam Taxation (on Goods carried by Roads or Inland Waterways) Act of 1954 imposes a direct restriction on the freedom of trade. Because the Act fails to satisfy the conditions laid down in article 304(b), the Court declared the Act to be void. In view of this declaration the Court found it unnecessary to examine the remaining arguments presented in support of the challenge to the Act’s validity. Accordingly, the three appeals and the two petitions were allowed, and the writs or orders prayed for were directed to be issued. The appellants and the petitioners were awarded costs against the respondent, and the judgment was authored by Justice Shah.

The Court then recounted the factual background of the challenge. The validity of the Assam Taxation (on Goods carried by Roads or Inland Waterways) Act, 1954—hereinafter referred to as “the Act”—was contested by a group of tea producers from the States of West Bengal and Assam. The Act had been enacted by the Assam Legislature and received the Governor’s assent on 9 April 1954. The Court noted that, at the time the Bill was introduced in the State Legislature, no prior sanction from the President had been obtained, nor had the President given any assent to the legislation. Section 3 of the Act provides, inter alia, that “manufactured tea in chests carried by motor vehicles, cart, trolley, boat, animal or human agency or any other means except railways and airways shall be liable to a tax of one anna per pound of such tea”, and that this tax is to be recovered from the producer.

Section 3 of the Assam Taxation (on Goods carried by Roads or Inland Waterways) Act, 1954 stipulates that the tax on tea shall be collected from the producer. The term “producer” is defined in section 2, clause (2) to mean any person who produces tea and also includes the individual who is in charge of the tea garden where the tea is produced. Under section 4, the amount of tax is calculated on the total net weight of tea that is carried during the specified return period. Section 7 requires that every producer and every dealer must file a return detailing the manufactured tea that is carried in chests. Section 23, clause (3), authorises the Commissioner of Taxes to recover any taxes or penalties that are due under the Act by treating them as arrears of land revenue. Sections 27 and 28 impose a duty on producers to keep accounts in the forms prescribed by the Act, to preserve those accounts, and to produce them whenever they are called upon by the Commissioner or by any other person appointed by the Government for that purpose. The rules made under the Act further obligate producers to submit quarterly returns to the Superintendent of Taxes and to maintain registers in the prescribed forms; failure to keep such registers attracts a penalty. In exercising the powers conferred by section 7, sub‑section (3), the Commissioner of Taxes issued a notification in the Assam Government Gazette stating that returns required under the Act and its Rules for the period from 1 June 1954 to 30 September 1954 had to be filed on or before 30 October 1954, and that returns for each subsequent quarter must be filed on or before the dates specified in the Gazette.

Three producers who had transported their tea by road or by inland waterways to Calcutta in the State of West Bengal filed petitions under article 226 of the Constitution in the High Court of Assam, challenging the authority of the Assam Legislature to enact the Act on the ground that the Act infringed the constitutional guarantee of freedom of trade, commerce and intercourse contained in article 301. The High Court rejected the petitioners’ plea. In response to the High Court’s decision, three appeals bearing certificates of fitness under article 132 of the Constitution were referred. Additionally, two other producers raised challenges to the validity of the Act by filing petitions under article 32 of the Constitution before this Court. The central issue presented in these proceedings is whether the Assam Legislature possessed the competence to enact the Act. The producers argue that article 301 declares trade, commerce and intercourse to be free throughout the territory of India, and that a statute that imposes a restriction or burden on that freedom by levying a tax without satisfying the constitutional conditions is invalid. They point to item 56 of List II of the Seventh Schedule of the Constitution, which authorises a State Legislature to impose taxes on goods and passengers carried by road or on inland waterways. Consequently, they contend that the tax imposed by the Act is a tax on goods carried by road and inland waterways and therefore falls within the legislative competence of the State, but that its effect on the constitutional guarantee of free trade must be examined.

In this case, the Court observed that the tax imposed by the Act was not a duty of excise. The Court explained that if the validity of the Act were to be examined solely on the basis of the power granted by Article 246, clause 3, read together with item 56 of List II of the Seventh Schedule, then the tax would fall within the legislative competence of the State. However, the Court stressed that the power conferred on Parliament and the State Legislatures by the legislative lists is limited by various constitutional provisions. By reference to Article 301, the Court noted that, subject to the provisions of Part XIII of the Constitution, trade, commerce and intercourse throughout the territory of India must be free. The language of that article, the Court said, is broad and allows no implications or exceptions except those expressly provided in Part XIII. It therefore sets out a comprehensive guarantee of freedom, defining clearly that trade, commerce and intercourse across India, subject to Part XIII, shall be free—that is, they shall not be prohibited, controlled, burdened or impeded unless expressly permitted. The Court further observed that, although the Constitution is federal in form, it contains numerous provisions emphasizing the unity of India, and to promote that unity it guarantees, subject to specific restrictions, freedom of trade, commerce and intercourse throughout the country. The Court distinguished Article 301 from the non‑justiciable directive principles of Part IV, describing it as a binding restriction on both legislative and executive powers. In addition to imposing an absolute bar on the executive, Article 301 also limits the legislative authority of Parliament and the State Legislatures under Articles 245, 246 and 248 and the relevant entries in the legislative lists that deal with trade, commerce and intercourse. The Court pointed out that while the power to tax trade, commerce and intercourse is subject to certain restrictions in Part XII—such as Articles 276, 286, 287, 288 and 289—these provisions do not exhaustively define the limits of that power. Moreover, the power to tax is further constrained by the fundamental freedoms in Part III, including Articles 14, 15(1), 19(1)(g) and 31(1), and also by Part XIII. Article 245, clause 1, expressly provides that the legislative powers of Parliament and the State Legislatures to enact laws are subject to the Constitution, and Article 301 is undeniably one of the constitutional provisions that bound those legislative powers. The Court then turned to the nature of taxation, stating that the power of taxation is essentially an attribute of State sovereignty and is not exercised for the purpose of protection or benefit to citizens or aliens. Its scope, the Court said, is not measured by the apparent need for the amount to be collected.

In this case, the Court observed that the power to tax is not an unlimited authority. Article 265 of the Constitution requires that any imposition of tax must be authorized by law, and the Constitution itself explicitly allocates taxing powers among the three lists in the Seventh Schedule. Consequently, the legislature must exercise the power of taxation strictly within the constitutional limits that have been prescribed. Any breach of those limits by either Parliament or a State Legislature is subject to judicial review. The Court further explained that the nature of a tax does not depend on the ability of citizens to meet the demand for services; rather, it is a charge to be collected irrespective of personal capacity. However, the Court emphasized that taxation remains a constrained power and must conform to constitutional provisions.

The Court then turned to the meaning of “trade and commerce.” It held that the term extends far beyond the simple exchange of goods for money or other goods. In modern conditions, trade and commerce encompass a wide variety of activities, including the carriage of persons and goods by road, rail, air and waterways; contracts; banking; insurance; transactions on stock exchanges and forward markets; communication of information; supply of energy; postal and telegraphic services; and many other forms of commercial intercourse that cannot be exhaustively listed. While the movement of goods may sometimes be an important component of commercial intercourse, it is not essential; commercial activities that do not involve physical movement are equally part of trade and commerce. The guarantee of freedom under Article 301 is therefore not limited to prohibitions of trade. It also covers tariffs, licensing requirements, marketing regulations, price controls, nationalisation, economic or social planning, discriminatory duties, compulsory appropriation of goods, freezing orders, and any similar impediment that directly affects commercial intercourse. Every step in the series of operations that constitute trade is an act of commerce, and any burden or restriction imposed on any such step constitutes a restriction on the freedom of trade, commerce and intercourse. The Court noted that this freedom is meant to be as wide as possible, protecting against prohibition, control, burden or impediment in commercial intercourse. Accordingly, not only discriminatory tariffs but also any taxation imposed on commercial intercourse, even when intended merely to raise revenue, falls within the scope of Article 301. The distinction between discriminatory tariffs and revenue‑raising taxation lies only in purpose, not in quality, and both types of burdens infringe the freedom guaranteed by the Constitution.

The Court further clarified that the guarantee of freedom is not confined solely to inter‑State movement or to restrictions on trade, commerce and intercourse in a narrow sense. Articles 302, 303, 304 and 306, which the Court intended to discuss subsequently, make it clear that the constitutional freedom envisaged includes all varied aspects of commercial intercourse, not merely the absence of barriers to movement between States. Thus, the protection afforded by Article 301 extends to the full spectrum of commercial activities, ensuring that neither tariffs nor taxes, nor any other regulatory measures, may unjustifiably curtail the free flow of trade, commerce and intercourse across the nation.

The Court observed that Article 301 was intended to secure freedom of trade, commerce and intercourse in every form, covering all activities that constitute commercial intercourse and not merely shielding those activities from the narrow phrase “trade, commerce and intercourse as such.” It noted that Article 301 places a limitation on the power of legislatures to enact laws under the entries in the Union and State lists that relate to trade, commerce and intercourse. The Court traced the underlying principle of Article 301 to the Constitution of the Commonwealth of Australia. It contrasted that source with the United States Constitution, pointing out that although the latter, in the eighth section of Article 1, grants Congress the authority to regulate commerce, it does not expressly guarantee a freedom of commerce comparable to that enshrined in the Indian Constitution. Section 92 of the Australian Constitution, the Court explained, declares in its first paragraph that “on the imposition of uniform duties of customs, trade, commerce and intercourse among the States, whether by means of internal carriage or ocean navigation, shall be absolutely free.” While this provision accords a guarantee of freedom of trade, commerce and intercourse, the Court held that it is not as expansive as the guarantee found in Article 301, though it follows a similar pattern. The Court then emphasized a crucial departure made by the Indian Constitution: whereas Section 92 protects freedom of trade, commerce and intercourse only among the States—that is, at the inter‑State level—the Indian guarantee extends throughout the entire territory of India, encompassing both intra‑State and inter‑State transactions. This broader territorial sweep, the Court stressed, does not change the substantive content of the freedom, which remains freedom from tax burdens and other impediments. The Court further observed that Section 92 of the Australian Act does not cover the wide freedom granted by Article 301; it merely safeguards trade, commerce and intercourse from restrictions in inter‑State commerce. Nevertheless, the Court found the interpretation of “free” given by the Judicial Committee of the Privy Council in James v. Commonwealth of Australia (LR (1936) AC 578) to be instructive for interpreting Article 301, since the Indian provision is largely modeled on the Australian section. Citing Lord Wright’s judgment in that case, the Court reproduced the passage where Lord Wright explained that “‘Free’ in s. 92 cannot be limited to freedom in the last mentioned sense (freedom from tariffs).” He warned that such a narrow view might initially appear plausible because of the temporal starting point of the provision, the surrounding sections, and the fact that the proviso relates to customs duties. However, Lord Wright concluded that the term embraces much more; customs duties and similar matters represent merely a pecuniary burden, and there may exist other, perhaps more drastic, ways in which freedom can be encumbered.

The Court explained that “free” does not mean only the absence of customs duties or the lack of a tariff barrier. It also includes protection against any restriction, whether partial or total, that prevents goods or persons from entering or leaving a State. The term “free” is not limited to a situation where there is no discrimination between inter‑State and intra‑State trade. While it is true that many measures that limit inter‑State trade also involve discrimination, such discrimination is not a necessary or decisive element of the concept of freedom. The Court noted that a compulsory seizure of goods could affect both goods intended for intra‑State commerce and goods meant for inter‑State trade without distinction. Moreover, freedom cannot be confined to freedom from legislative restraints alone; it must also encompass freedom from executive control. The Court stressed that every stage in a commercial transaction constitutes an act of trade, and that any State control over any of those stages interferes with the freedom of trade. These observations were made while considering a guarantee against obstruction of inter‑State trade and commerce, and they reflected a “conception” of freedom that includes freedom from customs duties, imports, border prohibitions and all similar restrictions. The Court described the purpose of this conception as ensuring that the people could trade with one another and move freely among the States without any burden, hindrance or restriction merely because they were not residents of the same State.

The Court further held that the freedom guaranteed by Article 301 of the Constitution is not absolute. It is subject to the limitations prescribed in Part XIII, which gives Parliament the authority to impose restrictions on trade, commerce and intercourse between States or within any part of the territory of India when such restrictions are required in the public interest. By this provision, the Constitution deliberately circumscribes the guarantee in Article 301, allowing Parliament to place restrictions that may be either intra‑State or inter‑State, provided they satisfy the public‑interest test. The Learned Attorney‑General argued that the courts lack competence to assess whether the amount and incidence of a tax imposed by a legislature are in the public interest, and therefore contended that Articles 301 and 302 do not address freedom from taxation or the limits that may be placed on such taxation. Counsel for the other side countered that modern political thought recognizes that the sovereign power of taxation is not confined to revenue collection alone; it is also employed to achieve broader social objectives such as justice, liberty and equality among citizens. Counsel asserted that the mere difficulty of examining the public‑interest justification of a tax does not mean that Article 302 does not cover restrictions on trade, commerce and intercourse that arise from taxation. The Court indicated that, in general, the judiciary will presume that taxes are imposed in the public interest, but this presumption does not prevent a court, in a particular case, from enquiring whether a legislative restriction satisfies the constitutional requirement of serving the public interest.

The Court observed that while courts normally respect the wisdom of Parliament and presume that taxes are imposed in the public interest, this presumption does not bar a court from examining whether a challenged statute meets the constitutional requirement of being “required in the public interest.” The Court further explained that if the judiciary can scrutinise the validity of a burden or impediment on trade, commerce, and intercourse that is not a tax, then the same presumption of constitutionality for a taxing statute cannot become a restriction on judicial jurisdiction.

The Court noted that clause (b) of Article 304 empowers State Legislatures to impose restrictions on the freedom of trade, commerce, and intercourse within the State when such restrictions are required in the public interest. Although the territorial reach of laws made under Articles 302 and 304(b) may differ because of the nature of the legislative authority, both Parliament and State Legislatures are entrusted with the power to restrict trade, commerce, and intercourse in the public interest. The Court stated that it is difficult to discern why the Constitution distinguishes between Parliament’s power to impose restrictions “as may be required in the public interest” and a State’s power to impose “reasonable” restrictions also “as may be required in the public interest.” The Court declined to analyse any substantive difference between the quality of restrictions that may be imposed by Parliament and those that may be imposed by State Legislatures under Articles 302 and 304(b).

According to the Court, both Articles require that any restriction on the freedom of trade, commerce, and intercourse satisfy the primary test of being “required in the public interest.” Clause (b) of Article 304 is qualified by a proviso that no bill or amendment concerning such restrictions may be introduced or moved in a State Legislature without the prior sanction of the President. Consequently, the authority of a State Legislature to enact legislation imposing restrictions is conditioned upon obtaining that presidential sanction before the bill or amendment is moved. By contrast, the Parliamentary power to impose restrictions is valid when the restrictions are required in the public interest, without a comparable presidential sanction requirement. The Court therefore explained that, for State Legislatures, two conditions apply: the restriction must be reasonable and required in the public interest, and the legislative proposal must obtain prior presidential sanction before being introduced. In this context, the Court may proceed to consider the implications of these constitutional provisions.

In its discussion, the Court referred to Article 255, which stipulates that a State law cannot be declared invalid merely because the Constitution‑required prior sanction was not obtained, provided that the President gave assent to the law under clause (c). The Court explained that even where a Bill or amendment falling within clause (b) of Article 304 was introduced without the President’s prior sanction, the resulting Act would nevertheless remain valid if the President subsequently signified assent to that Act. The Court then turned to Article 303(1), describing it as an exception to both Article 302 and Article 304(b). While Articles 302 and 304(b) grant Parliament and State Legislatures broad authority to enact laws that restrict the freedom of trade, commerce, and intercourse, Article 303 imposes a prohibition on exercising that power to grant any preference to one State over another or to authorize any discrimination between States on the basis of any entry relating to trade and commerce in any of the Lists of the Seventh Schedule. Clause (1) of Article 303, the Court noted, underscores the constitutional purpose of preserving the nation’s economic unity and preventing division among the constituent States in matters of trade and commerce. Although clause (1) of Article 302 bars discrimination in a law made under an entry relating to trade and commerce in the Seventh Schedule, the Court clarified that the prohibition is not confined only to items expressly listed as trade and commerce matters. The expression “relating to trade and commerce” in Article 302(1), according to the judgment, embraces all entries in the Seventh Schedule that confer the power to legislate, directly or indirectly, over activities of a trade or commerce nature. By contrast, clause (2) of Article 303 slightly relaxes the strictness of clause (1) with respect to laws made by Parliament. That provision authorises Parliament—not the State Legislatures—to enact laws that would otherwise be prohibited by clause (1) when a statute declares it necessary to make such discrimination to address a situation of scarcity of goods in any part of India. Finally, the Court examined Article 304 to the extent it was relevant, observing that notwithstanding anything in Articles 301 or 303, a State Legislature may, by law, levy on goods imported from other States or Union territories any tax that is similarly imposed on comparable goods manufactured or produced within that State.

In this portion of the judgment, the Court explained that the State Legislature could impose a tax on goods imported from another State or Union territory provided that the same tax was also levied on goods that were manufactured or produced within the State, and that such taxation did not create discrimination between imported goods and locally produced goods. This provision, found in clause (a) of Article 304, operated notwithstanding the general freedoms guaranteed by Articles 301 and 303, on the condition that the tax on imported goods was imposed without discriminatory intent. The Court observed that if Articles 301 and 303 did not address restrictions or burdens in the form of taxation, the purpose of the non‑obstante clause in Article 304(1) would be difficult to understand. The Court further noted that the provisions of Part XIII of the Constitution did not create new, independent powers of taxation; rather, the authority to tax was derived from Articles 245, 246 and 248 together with the entries in the Seventh Schedule, and the provisions of Part XIII merely limited the exercise of that legislative power. The fact that the Constitution singled out a specific field of taxation as an exception to the freedoms in Articles 301 and 303 strongly indicated that taxation itself was regarded as a restriction from which the guarantee of free trade, commerce and intercourse protected the public.

The Court then turned to clause (b) of Article 304, which required prior presidential sanction before a bill or amendment imposing any restriction on the freedom of trade, commerce or intercourse could be moved or introduced. No such presidential approval was required for laws imposing non‑discriminatory tariffs under clause (a). Nevertheless, the Court held that the nature of the restrictions contemplated by clauses (a) and (b) was not fundamentally different. Clause (b) addressed a general restriction that could include a tax burden, whereas clause (a) dealt with a specific tax burden limited to a particular field. The Court further explained that Article 305 preserved existing laws except where the President ordered otherwise, and also validated certain pre‑Constitution enactments, while authorising future legislation by Parliament and State Legislatures on matters mentioned in sub‑clause (2) of clause (6) of Article 19. Finally, the Court noted that Article 306, which had been repealed by the Constitution (Seventh Amendment) Act, 1956, had previously allowed a State listed in Part B of the First Schedule, which before the Constitution’s commencement had levied a tax or duty on the import or export of goods, to continue doing so if an agreement between the Government of India and that State permitted it. This historical provision reinforced the view that the freedom guaranteed by Article 301 was intended to encompass freedom from taxation, and that Articles 302 and 304 contemplated the imposition of tax‑type burdens as permissible restrictions.

In this case the Court observed that an agreement entered into between the Government of India and the Government of the particular State permitted that State to continue levying and collecting the tax or duty, provided the terms of the agreement were observed. The marginal note to the relevant constitutional article explained that the power granted to the States listed in Part B of the First Schedule to levy tax was to be understood as a power to impose restrictions on trade and commerce. This interpretation supported the view that, within the meaning of Article 301, the freedom guaranteed to trade and commerce also encompassed freedom from taxation, and that the restrictions contemplated by Articles 302 and 304 were intended to cover burdens of a fiscal nature. On a careful review of the various provisions, the Court held that Part XIII of the Constitution placed limitations on the legislative authority given by Articles 245, 246 and 248 and on the entries in the Seventh Schedule for both Parliament and the State Legislatures. Those limitations expressly included burdens in the nature of taxation. Consequently, the power to tax commercial intercourse that was vested in the legislative lists of either Parliament or the State Legislatures was circumscribed by Part XIII, and any exercise of that power which failed to meet the requirements of Part XIII would be deemed invalid.

The Court further noted that the earlier sanction of the President had not been obtained before the Bill that became the impugned Act was moved in the Assembly. Although the Assam Legislature possessed authority under item 56 of the Seventh Schedule to impose the tax, the State could not exercise that authority in the absence of prior presidential sanction, and the invalidity of the Act imposing the tax on goods and passengers was not cured because the President never assented to the Act after its passage by the Assam Legislature. The argument that this view severely curtailed the “sovereignty” of the States was considered to have little merit. A brief examination of the constitutional scheme revealed that the Constituent Assembly’s primary aim was to create a strong central Government capable of fostering a healthy economy and unifying the various component States, which included former British Indian provinces and merged princely states, by subordinating local parochial interests to the broader national interest. Accordingly, when determining the validity of a statute, any impact that the Court’s interpretation might have on a cherished notion of State sovereignty must be disregarded. In light of this analysis, the Court concluded that the Assam Taxation (on Goods carried by Roads or Inland Waters) Act, 1954 infringed the guarantee of freedom of trade and commerce under Article 301, because the Bill that was moved in the Assembly had not received the President’s assent as required by the proviso to Article 304(b), and the Act had not been validated by assent under Article 255(c).

The Court observed that, although several subsidiary arguments had been raised before the Bar, it was not necessary to discuss those matters in detail. The subsidiary contentions included the proposed application of the pith and substance doctrine to interpret the relevant statutory clauses, an allegation that the Act violated the Constitution’s equal protection provisions, and an inquiry into the effect of Act XXIX of 1953 enacted by Parliament. Having considered that these issues were not essential to the principal determination, the Court declined to examine them further. Consequently, the Court affirmed that the appeals should be allowed and that the rule applied in the two pending applications should be made absolute, directing that the successful parties be awarded costs. In the operative portion of the order, the Court, relying on the reasoning expressed in the majority judgment, ordered that both the appeals and the writ petitions be allowed. The order also stipulated that costs be awarded, specifying that the award would consist of a single set of hearing fees, rather than multiple costs assessments. This comprehensive direction concluded the proceedings, reflecting the Court’s final disposition of the matters before it.
