Criminal law practice before the Supreme Court of India

Juvenile Justice Cases before the Supreme Court.

Age-determination challenges Lawyer in Supreme Court of India

Age-determination challenges before the Supreme Court of India arise when a criminal proceeding that has already produced a final judgment or a final order of conviction, remand, or sentencing is contested on the ground that the accused was, at the time of the alleged offence, a child as defined under the Juvenile Justice (Care and Protection of Children) Act, and the statutory and procedural framework governing such challenges is anchored in the applicable criminal procedure law which permits a petition for special leave to be entertained by the apex court only when the question raised is of substantial importance, involves a jurisdictional defect, or implicates a fundamental right, thereby establishing a high threshold for maintainability that requires the petitioner to demonstrate that the age of the accused is determinative of the court’s jurisdiction and that the lower tribunal’s decision was rendered without proper consideration of the requisite medical or forensic evidence; the procedural route for invoking the Supreme Court’s jurisdiction in this context typically commences with the filing of a special leave petition, which, if entertained, may be followed by a detailed written statement, a supporting annexure of age-assessment reports, and, where appropriate, a request for a direction to the appropriate authority to conduct a fresh age-determination exercise, all of which must be presented within the period prescribed by the present procedural framework and must satisfy the court’s discretion that the matter is not merely an appeal of fact but a question of law or jurisdiction that the Supreme Court is empowered to resolve; the nature of the question presented in an age-determination challenge is fundamentally distinct from ordinary criminal appeals because it seeks to establish whether the accused falls within the protective ambit of the juvenile justice regime, which, if affirmed, would render the conviction, sentence, or custodial order invalid, and consequently the Supreme Court’s intervention is limited to assessing whether the lower court correctly applied the statutory definition of a child, whether it adhered to the procedural safeguards mandated for age assessment, and whether any violation of those safeguards warrants setting aside or modifying the impugned order, rather than re-examining the entire evidentiary matrix of the case; the Supreme Court context is procedurally different from ordinary criminal litigation in that the apex court does not entertain a full rehearing of factual issues, but rather exercises its discretionary power to intervene only when a substantial error of law, a jurisdictional flaw, or a breach of constitutional guarantee is evident, and this limitation is reflected in the court’s practice of issuing directions for a fresh age-determination report, remanding the matter to the appropriate juvenile justice board, or, in rare circumstances, granting relief that aligns the outcome with the statutory scheme applicable to children in conflict with law; the order or record that typically gives rise to an age-determination challenge is a final judgment of conviction, a sentencing order imposing an adult penalty, a remand order authorising continued detention, or a discharge order that fails to consider the accused’s age, and the petitioner must attach the certified copy of such order, the trial court’s findings on age, any medical or radiographic evidence, and a detailed affidavit explaining the alleged defect, thereby ensuring that the Supreme Court’s registry has a complete paper-book that can be scrutinised for jurisdictional competence and procedural compliance; maintainability of the petition hinges upon the demonstration that the age issue is material to the jurisdiction of the court that rendered the impugned order, that the petitioner has complied with the limitation period prescribed by the present procedural framework, that the petition is not frivolous or an attempt to re-litigate factual determinations, and that the petitioner has exhausted any alternative remedial avenues such as a review or curative petition before approaching the apex court, all of which collectively satisfy the stringent threshold for the Supreme Court to entertain the challenge; finally, it is essential for the litigant to understand that the Supreme Court will not re-hear the case as an ordinary appellate forum, but will, upon finding merit in the age-determination challenge, either set aside the impugned order, remit the matter to a competent juvenile justice authority for fresh determination, or, where appropriate, stay the execution of the order pending compliance with statutory safeguards, and that dismissal of the petition or issuance of a notice to show cause will have immediate consequences on the custodial status of the accused, potentially leading to continued detention until the procedural requirements are satisfied or, conversely, to release if the court determines that the age-determination defect renders the original order untenable.

Jurisdictional basis for Supreme Court review of age-determination challenges in criminal appeals

The Supreme Court may entertain a petition challenging the age determination of an accused only when the alleged age directly affects the jurisdiction of the lower tribunal that rendered the conviction, because the juvenile justice regime confers exclusive competence to juvenile justice boards for children, and a mischaracterisation of age therefore creates a jurisdictional defect that the apex court is empowered to correct. To establish that jurisdictional defect, the petitioner must demonstrate that the lower court or the sentencing authority applied adult procedural law despite the accused being a child at the time of the alleged offence, and that such misapplication invalidates the legal basis of the conviction, sentencing, or remand order, thereby rendering the entire proceeding ultra vires. The procedural gateway for invoking this jurisdictional review is the filing of a special leave petition, which requires the petitioner to articulate with specificity how the age-determination issue is not a mere factual dispute but a question of law that determines the competence of the adjudicating body, and to attach a certified copy of the impugned order, the original age-assessment report, and any subsequent medical or radiographic evidence that was either ignored or improperly evaluated by the lower court. The Supreme Court’s registry, upon receipt of the petition, constructs a paper-book that includes the trial court’s judgment, the forensic age-determination report, the affidavit of the petitioner, and any orders of review or curative petitions previously filed, and the court scrutinises this compilation to ascertain whether the lower forum possessed the statutory authority to impose an adult sentence on a person who, according to the evidence, was below the age threshold fixed under the juvenile justice legislation. In assessing jurisdiction, the apex court applies a two-pronged test: first, whether the age of the accused at the time of the alleged offence falls within the definition of a child under the applicable juvenile justice law, and second, whether the lower tribunal adhered to the mandatory procedural safeguards, such as the requirement of a medical board assessment, before concluding that the accused was an adult, and any failure on either count constitutes a jurisdictional infirmity justifying Supreme Court intervention. When the Supreme Court finds that the jurisdictional defect is established, it may exercise its discretionary powers to either set aside the impugned order in its entirety, remit the matter to the appropriate juvenile justice board for a fresh age-determination exercise, or, in exceptional circumstances, stay the execution of the order pending compliance with the procedural safeguards, thereby providing interim protection to the accused against continued detention. The consequences of a dismissal of the petition or a notice to show cause are significant, because a dismissal typically leaves the original adult conviction and sentence intact, which may result in the continuation of custodial measures, whereas a notice to show cause may trigger a temporary stay of execution, allowing the accused to remain out of prison while the court evaluates the merits of the jurisdictional claim. Moreover, if the Supreme Court remands the case for fresh age assessment, the lower tribunal must convene a multidisciplinary medical board, ensure that the board’s findings are recorded in a certified report, and then transmit that report to the juvenile justice board, which will determine the appropriate remedial order, such as placement in a child welfare institution or modification of the sentence to align with the juvenile justice framework. Throughout this process, the petitioner must remain vigilant about compliance with the limitation period prescribed by the present procedural framework, because any delay beyond the statutory time limit may be construed as a waiver of the right to raise the jurisdictional challenge, and the Supreme Court may refuse to entertain the petition on the ground of procedural default, thereby extinguishing the prospect of relief. In sum, the jurisdictional basis for Supreme Court review of age-determination challenges hinges on the principle that an erroneous classification of a child as an adult deprives the juvenile justice system of its exclusive competence, and the apex court’s role is confined to correcting that jurisdictional error, ensuring that the final adjudication respects the protective scheme intended for children in conflict with law.

Maintainability criteria and limitation periods for filing a petition challenging age determination

For a petition challenging the age determination of an accused to be deemed maintainable before the Supreme Court, the petitioner must establish that the question raised transcends mere factual dispute and directly impinges upon the jurisdictional competence of the lower tribunal that rendered the impugned conviction, sentencing, or remand order, thereby satisfying the threshold of a substantial question of law or jurisdiction required by the present procedural framework. In addition, the petitioner is required to demonstrate that all alternative remedial avenues, including a review petition before the same court, a curative petition, or any statutory remedy under the juvenile justice scheme, have been duly exhausted or are unavailable, because the Supreme Court will not entertain a fresh challenge where a competent forum remains open to address the alleged age-determination defect. The limitation period applicable to such a petition is governed by the present procedural framework which prescribes that a petition for special leave challenging a final order must be filed within twelve months from the date on which the petitioner becomes aware, or ought to have become aware, of the material fact that the age of the accused at the time of the alleged offence was below the statutory threshold, and any delay beyond this period is ordinarily fatal to maintainability unless the petitioner can establish a satisfactory cause of delay recognized by the apex court. The petition must be accompanied by a meticulously compiled paper-book that includes the certified copy of the impugned judgment or order, the original forensic age-assessment report, any subsequent medical or radiographic evidence, the affidavit of the petitioner setting out the factual matrix, and copies of all prior review or curative petitions, because the registry will scrutinise each document to verify that the age-determination issue was either omitted or incorrectly evaluated at the lower level. The legal test applied by the Supreme Court to ascertain maintainability requires a two-fold inquiry: first, whether the age of the accused at the relevant time falls within the definition of a child as prescribed by the juvenile justice legislation, and second, whether the lower forum complied with the mandatory procedural safeguards, such as the constitution of a multidisciplinary medical board and the recording of its findings in a certified report, because a failure on either prong establishes a jurisdictional infirmity that renders the impugned order vulnerable to setting aside. Should the Supreme Court, after preliminary scrutiny, issue a notice to show cause rather than dismiss the petition outright, the immediate practical effect is often a stay of execution of the impugned order, which may result in the release of the accused from custodial detention pending final determination, whereas a dismissal without any stay leaves the original adult conviction and sentence intact, thereby perpetuating the custodial consequences until the petitioner seeks alternative relief, if any, under the procedural law. If the petitioner files the petition beyond the prescribed twelve-month limitation without establishing a cogent justification such as suppression of evidence, concealment by authorities, or a bona fide belief that the age issue could not have been raised earlier, the Supreme Court is likely to invoke the doctrine of procedural default and refuse to admit the petition, thereby extinguishing the avenue for any judicial correction of the age-determination defect and leaving the original order to operate without interruption. Consequently, a litigant intending to challenge the age determination must, at the earliest opportunity after discovering the material fact, assemble the requisite forensic and medical documentation, verify that no pending review or curative remedy remains, calculate the exact date from which the twelve-month limitation accrues, and file a meticulously drafted special leave petition within that period, because adherence to these procedural prerequisites determines whether the Supreme Court will entertain the challenge, grant interim protection, remit the matter for fresh assessment, or ultimately dismiss the petition, each outcome carrying distinct ramifications for the accused’s liberty, custodial status, and the ultimate applicability of the juvenile justice framework.

Preparation and authentication of the age-determination record for Supreme Court scrutiny

When a petitioner seeks Supreme Court review of an alleged mis-determination of age, the first indispensable requirement is the preparation of a comprehensive, authenticated age-determination record that can withstand the apex court’s exacting standards of evidentiary reliability and procedural regularity. The record must commence with a certified copy of the impugned judgment, sentencing order, or remand decree, each bearing the original court seal, the date of issuance, and a clear indication of the operative provisions that were applied to an adult accused. Immediately following the judgment copy, the petitioner must annex the original forensic age-assessment report prepared by a multidisciplinary medical board, ensuring that the report contains the names, qualifications, and signatures of all participating specialists, the methodology employed, the radiographic or dental findings, and the conclusive age estimate expressed in years and months. Each radiographic image or dental orthopantomogram that underlies the age estimate must be reproduced in the annexure as a certified true copy, stamped by the radiology department, and accompanied by a declaration from the technician confirming the chain of custody from the time of capture to the submission of the report. In addition to the medical documentation, the petitioner is required to file an affidavit sworn before a notary public or a magistrate, wherein the deponent narrates the factual circumstances of the alleged age-determination error, identifies any procedural lapse such as denial of a medical board hearing, and expressly attests to the authenticity of every document annexed to the paper-book. The affidavit must be accompanied by a verification clause stating that the deponent has personally examined each annexure, that no alteration or omission has been made since the original preparation, and that the deponent is aware that any false statement may attract penal consequences under the applicable law. Before the petition is presented to the Supreme Court registry, the advocate-on-record is obligated to obtain a certificate of authenticity from the senior counsel, confirming that the entire paper-book complies with the procedural requisites laid down in the present procedural framework and that the record is fit for judicial scrutiny. The registry, upon receipt of the authenticated paper-book, creates a master file in which each annexure is indexed, the signatures are cross-checked against the original seals, and any discrepancy such as a missing signature or an illegible seal triggers an immediate requisition for clarification before the petition can be listed for hearing. If the registry finds that the age-determination report was not signed by a qualified paediatric radiologist or that the medical board did not include a forensic odontologist, the Supreme Court may either direct the petitioner to procure a supplementary report within a stipulated time or may dismiss the petition on the ground of non-compliance with mandatory evidentiary standards. Conversely, when the authentication process is flawless, the Supreme Court is empowered to issue an interim protection order that stays the execution of the adult sentence, thereby releasing the accused from custody pending a substantive determination of whether the age-assessment record satisfies the statutory threshold for juvenile jurisdiction. Should the Court, after examining the authenticated record, conclude that the age estimate falls below the statutory limit, it may remand the matter to the appropriate juvenile justice board, directing that the board adopt the age-determination report as the operative basis for ordering placement in a child welfare institution or for modifying the sentence in accordance with the juvenile justice scheme. In the event that the authenticated record is found deficient, the Supreme Court may either dismiss the petition outright, thereby leaving the original adult conviction and its attendant custodial consequences untouched, or may issue a limited stay coupled with a directive to the lower court to rectify the procedural lapse, which can result in a temporary reprieve for the accused while the requisite forensic examination is undertaken.

Evidentiary standards and admissibility of medical, dental, and anthropometric evidence before the apex court

In the context of an age-determination challenge before the Supreme Court of India, the court’s first duty is to ascertain whether the medical, dental, or anthropometric material submitted by the petitioner satisfies the evidentiary threshold of relevance, reliability and probative value as required by the prevailing principles of the admissibility regime. The Supreme Court, while exercising its discretionary jurisdiction, applies the well-settled test that expert opinion must be founded upon a scientifically accepted methodology, must be rendered by a duly qualified specialist, and must be accompanied by a contemporaneous report that records the chain of custody from the moment of evidence collection to its submission in the paper-book. Consequently, a forensic age-assessment report that relies solely on visual inspection without radiographic or dental imaging, or that is prepared by a practitioner lacking formal training in paediatric radiology or forensic odontology, is ordinarily deemed insufficient to meet the reliability criterion and is likely to be excluded as inadmissible expert evidence. The apex court further requires that each radiographic plate, orthopantomogram or anthropometric measurement be reproduced as a certified true copy bearing the official seal of the issuing laboratory, together with a declaration from the technician confirming that the original image has not been altered, thereby satisfying the procedural demand for authentication and preventing any allegation of tampering. In addition, the Supreme Court insists that the affidavit accompanying the age-determination dossier must expressly state the date on which the forensic examination was conducted, the identity of every expert who participated, the specific techniques employed—such as Greulich and Pyle atlas comparison for skeletal maturity or Demirjian’s method for dental development—and must affirm that the conclusions were reached independently of any investigative or prosecutorial influence. When the petition is listed, the registry verifies that the paper-book contains the original signed report, the certified copies of all radiographs, the expert affidavit and the verification clause, and any omission—such as the absence of a dental specialist’s signature on a dental age estimate—triggers an immediate requisition for clarification before the matter can proceed to substantive hearing. If the court determines that the medical evidence satisfies the twin requisites of scientific acceptance and procedural authentication, it may exercise its inherent power to stay the execution of the adult sentence, thereby granting the accused interim protection while the lower tribunal is directed to re-evaluate the age issue in accordance with the juvenile justice framework. Conversely, where the Supreme Court finds that the forensic report is deficient because it lacks a multidisciplinary board, relies on outdated reference standards, or fails to disclose the precise measurement methodology, the court is empowered to deem the evidence inadmissible, to dismiss the petition as untenable, and to allow the original conviction and custodial order to continue unabated. The Supreme Court has also articulated that, even when the age-determination evidence is admissible, the court must assess whether the estimate falls below the statutory age threshold, and if the estimate is marginally above the threshold, the court may still order a fresh assessment to eliminate any doubt, thereby ensuring that the protective intent of the juvenile justice legislation is not frustrated by a borderline scientific conclusion. In practice, the Supreme Court’s rulings on admissibility have created a de facto requirement that the petitioner procure a contemporaneous multidisciplinary age-assessment report before filing the special leave petition, because failure to do so typically results in the petition being dismissed on procedural grounds without any substantive consideration of the underlying age question. Should the apex court, after a thorough examination of the authenticated record, conclude that the age-determination evidence is both admissible and indicative of minority, it may issue an order remanding the case to the appropriate juvenile justice board, directing that the board adopt the forensic report as the operative basis for placing the child in a child-care institution or for modifying the sentence in conformity with the juvenile justice scheme. In contrast, where the Supreme Court finds the evidence inadmissible or the age estimate to exceed the statutory limit, the court typically affirms the lower court’s adult conviction, may refuse bail or any stay of execution, and the accused remains subject to the original custodial consequences, thereby underscoring the pivotal role of rigorous forensic documentation in determining the ultimate fate of the litigant.

Framing of relief: directions for re-determination, stay of trial, or modification of sentence

When a petitioner approaches the Supreme Court seeking redress for an alleged mis-determination of age, the first operative step is the precise articulation of the relief sought, which must be framed in a manner that aligns with the court’s limited jurisdiction to either order a fresh forensic assessment, to stay the operative consequences of the impugned order, or to modify the sentence in conformity with the juvenile justice regime. The petition must expressly state whether the relief demanded is a direction for the lower court or the juvenile justice board to constitute a multidisciplinary medical board, to undertake radiographic and dental examinations, and to issue a certified age-assessment report that will become the controlling basis for any subsequent jurisdictional determination. If the petitioner instead seeks an interim stay of the trial, execution of the sentence, or release from custodial detention, the relief clause must invoke the principle that the existence of a credible age-determination defect creates a substantial risk of irreparable injury, thereby justifying the exercise of the Supreme Court’s inherent power to suspend the operation of the impugned order pending final adjudication on the age issue. When the relief sought is a modification of the sentence, the petitioner must demonstrate that the original sentencing authority acted without jurisdiction because the accused was a child at the material time, and consequently the court may order that the adult penalty be replaced by the appropriate juvenile disposition, which may include placement in a child welfare institution, a reduced term of liberty, or a non-custodial corrective measure prescribed under the juvenile justice framework. The court’s assessment of the adequacy of the relief request is conducted on the basis of the paper-book, which must contain the original judgment, the forensic report, the affidavit of the petitioner, and any prior orders of review, because the registry will reject a petition that fails to demonstrate that the relief is anchored in a demonstrable jurisdictional flaw rather than a mere disagreement with factual findings. If the Supreme Court, after scrutinising the record, finds that the age-assessment evidence meets the reliability threshold and indicates minority, it may issue a direction that the lower court vacate the adult conviction, remand the matter to the juvenile justice board for appropriate disposition, and simultaneously stay any execution of the sentence, thereby providing immediate protective relief to the accused. Conversely, where the court determines that the forensic report is either inadmissible or shows that the accused was above the statutory age, the relief may be limited to a denial of stay, an affirmation of the original sentence, and a possible direction that the petitioner bear the costs of the proceedings, which underscores the practical consequence that an unsuccessful framing of relief results in the continuation of the adult penalty and any associated custodial ramifications. Therefore, the precise framing of relief, whether it seeks re-determination, interim stay, or sentence modification, must be supported by a meticulously compiled record, must satisfy the jurisdictional test, and must articulate the concrete legal consequences sought, because the Supreme Court’s discretion to grant any of these remedies is exercised only after a rigorous examination of the evidentiary foundation and the procedural regularity of the age-determination process.

Interim relief mechanisms including bail, suspension of sentence, and protection of liberty pending adjudication

When an age-determination challenge is presented before the apex court, the petitioner may seek interim protection of liberty, and the court’s power to grant such protection is exercised through mechanisms such as bail, suspension of the operative sentence, or a stay of execution, each of which requires a distinct evidentiary showing that continued deprivation of freedom would cause irreparable injury. In order to obtain bail pending the final determination of the age issue, the petitioner must file a detailed application before the Supreme Court registry, attaching the authenticated age-assessment report, the original conviction order, and a sworn affidavit demonstrating that the alleged mis-determination directly affects jurisdiction and that the accused is likely to be classified as a child, thereby satisfying the court’s test that bail may be granted where the charge is not of a nature that endangers public safety and where the petitioner can show that the custodial consequences would be disproportionate to the alleged offence. The Supreme Court, while exercising its inherent jurisdiction to stay the execution of a sentence, typically requires the petitioner to demonstrate that the age-assessment evidence is not merely speculative but has been produced by a qualified multidisciplinary board, that the report indicates the accused falls below the statutory age threshold, and that the lower court failed to consider this report, thereby establishing a clear nexus between the procedural defect and the risk of continued incarceration that would contravene the protective purpose of the juvenile justice framework. If the court is persuaded that the procedural lapse is material, it may issue an interim order staying the operation of the sentencing decree, which automatically results in the release of the accused from prison unless the registry records indicate that the order is subject to a separate custodial direction, in which case the court may direct the custodial authority to place the accused under protective supervision rather than ordinary imprisonment until the age issue is finally resolved. Conversely, where the petitioner fails to produce a contemporaneous forensic report or where the age-assessment findings are ambiguous, the Supreme Court may refuse bail and may decline to suspend the sentence, reasoning that the risk of releasing an individual who may not qualify as a child outweighs the speculative benefit of interim liberty, and consequently the accused remains in custody pending the final adjudication of the jurisdictional question. The procedural record that the registry examines for any interim relief application must contain, in addition to the age-assessment report, the original sentencing order, a copy of the notice of appearance filed by the accused, the affidavit of the petitioner outlining the alleged procedural defect, and a verification that the petitioner has complied with the limitation period prescribed for filing a special leave petition, because any lapse in these documentary requirements may be treated as a fatal defect that precludes the court from granting bail or a stay. When the Supreme Court ultimately decides to grant interim protection, it typically frames the order in terms of a conditional stay, specifying that the accused shall remain out of prison provided that the petitioner files a fresh age-determination report within a time-frame fixed by the court, and that any violation of the conditions may result in the immediate revocation of the stay and the re-imposition of the original sentence, thereby balancing the need to safeguard liberty against the imperative of ensuring compliance with procedural directives. Thus, the practical consequence of a successful interim relief application is the temporary restoration of personal liberty and the suspension of any punitive measures, whereas an unsuccessful application results in the continuation of custodial deprivation, and in either scenario the Supreme Court’s interim order remains subject to modification or reversal on the merits of the age-determination challenge, underscoring the pivotal role of meticulous record preparation and timely filing in securing any protective relief.

Consequences of dismissal or adverse order: impact on conviction, sentencing, and collateral consequences

When the Supreme Court either dismisses a petition challenging the age-determination of an accused or issues an adverse order affirming the lower tribunal’s findings, the legal ramifications extend far beyond the mere procedural outcome, affecting the very foundation of the conviction, the enforceability of the sentence, and a spectrum of ancillary rights that flow from a criminal judgment. A dismissal that is predicated on the finding that the age-assessment evidence was either inadmissible or insufficient to establish minority thereby leaves the original conviction untouched, meaning that the statutory presumption of guilt continues to operate and the judgment remains a binding precedent for any subsequent criminal or civil proceedings involving the same factual matrix. Conversely, if the adverse order expressly confirms that the accused was an adult at the material time, the Supreme Court’s affirmation validates the lower court’s jurisdiction, thereby cementing the sentencing order and rendering any request for modification or commutation of the penalty ineffective unless pursued through a separate statutory review mechanism. The practical impact of such a dismissal or adverse affirmation on collateral consequences includes the continuation of any custodial deprivation, the preservation of the criminal record as a conviction, the denial of statutory benefits such as parole or remission, and the perpetuation of restrictions on voting, employment, and professional licensing that are triggered by a standing adult conviction. From a procedural standpoint, the Supreme Court’s order is entered into the official case file, annotated as a final determination, and the registry subsequently issues a certified copy to the lower court, which must then enforce the order without further judicial review, thereby precluding any additional stay or remand on the basis of the same age-determination issue. If the dismissal is accompanied by a directive that the petitioner bear the costs of the proceedings, the financial burden becomes an additional collateral consequence, potentially affecting the accused’s ability to fund future legal challenges or to meet any statutory restitution obligations imposed by the original conviction. In circumstances where the Supreme Court stays the execution of the sentence pending a fresh age-determination, the interim release of the accused from prison is conditional upon compliance with any procedural timetable imposed by the apex court, and any breach of those conditions may trigger an immediate revocation of the stay and reinstatement of the original custodial order. Should the adverse order affirm the adult status, the accused remains subject to the full force of the original sentence, including any period of imprisonment, fines, or community service, and the conviction continues to serve as a legal impediment to the issuance of any future pardon, commutation, or reduction of the penalty under separate statutory schemes. Finally, the legal effect of dismissal or adverse affirmation on any pending or future petitions is that the Supreme Court’s determination constitutes a final bar to re-litigating the same age-determination issue, thereby obligating the petitioner to explore alternative avenues such as a review of the forensic report under the applicable procedural law, or to accept the operative consequences of the affirmed conviction.
