Gait Analysis, Clothing Seizure and Fast‑Track Trial: Emerging Evidentiary and Procedural Issues in the Pune Ketan Agarwal Case

Police in Pune have initiated a forensic examination known as gait analysis in connection with the case involving the death of realtor Ketan Agarwal at Lohagarh Fort. The accused, identified as Chetan Chaudhary, is alleged to have pushed Mr Agarwal from the fort premises, an act purportedly motivated by his relationship to Agarwal’s fiancée, Siya Goyal. Investigators seek to match Chaudhary’s walking pattern with that of a hooded individual captured on CCTV footage near the scene, employing gait analysis as a comparative tool. The police have also requested the procurement of Chaudhary’s clothing worn on the day of the incident to facilitate a more comprehensive crime‑scene forensic reconstruction. The ongoing investigation is proceeding toward a fast‑track trial, indicating the authorities’ intent to expedite lawful judicial proceedings once sufficient evidentiary material is finally assembled. The use of gait analysis raises questions concerning its scientific reliability, admissibility substantially under evidentiary law, and compatibility with constitutional guarantees of a fair trial. Furthermore, the request for Chaudhary’s clothing implicates strict procedural safeguards governing searches, seizures, and the right against self‑incrimination during the investigative phase under the law. The fast‑track trial designation may affect bail considerations, the scope of pre‑trial detention, and the standards applied by the court in reviewing relevant evidentiary material. The credibility of gait analysis will likely be examined in light of judicial precedents addressing scientific evidence, including the requirement that the method be generally accepted by the relevant scientific community. Ultimately, the outcome of the forensic comparison and the court’s assessment of procedural propriety may shape the evidentiary foundation upon which the prosecution builds its case against the accused.

One central legal question is whether gait analysis can satisfy the admissibility criteria set forth in the Bharatiya Sakshya Adhiniyam, which demands that scientific evidence be reliable, relevant, and based on methods that enjoy general acceptance within the pertinent scientific community. The courts have previously applied a reliability test that examines the methodology's error rate, peer‑review status, and the existence of standardized protocols, thereby requiring the prosecution to produce expert testimony establishing these parameters before the evidence can be admitted. If the forensic laboratory conducting the gait comparison lacks accreditation or if the comparative database is not publicly disclosed, the defence may argue that the technique fails the statutory threshold of scientific certainty, potentially leading to its exclusion. Consequently, the court’s decision on admissibility will likely hinge on the presence of a qualified expert who can articulate the method’s validity and on the prosecution’s ability to demonstrate that the analysis meets the stringent standards prescribed by the legislation.

Another pivotal issue concerns the police request for Chaudhary’s clothing, which implicates the constitutional guarantee of personal liberty and the procedural safeguards embedded in Article 21 of the Constitution, demanding that any intrusion be reasonable and legally sanctioned. Under the Code of Criminal Procedure, a search of personal effects generally requires a valid warrant unless exigent circumstances exist, and the authority must document the basis for the search to ensure compliance with due‑process requirements. If the investigators can demonstrate that the clothing is essential for establishing a link between the accused and the alleged hooded figure, the court may deem the seizure proportionate, yet the defence retains the right to challenge the necessity and scope of the request. Any failure to adhere to the statutory safeguards could give rise to a violation of the accused’s right against self‑incrimination, potentially rendering the obtained evidence inadmissible under the principle that evidence derived from an illegal search must be excluded.

The designation of a fast‑track trial introduces procedural considerations relating to bail, as the accelerated timeline may limit the opportunity for the defence to compile counter‑evidence, thereby prompting the judiciary to scrutinise whether the speed of the process compromises the presumption of innocence. Under the CrPC, bail may be granted unless the offence is non‑bailable or the court believes the accused is likely to tamper with evidence, and in fast‑track cases the court must balance the State’s interest in swift justice against the individual’s right to a fair hearing. Should the court determine that the reliance on gait analysis and clothing evidence is central to the prosecution’s case, the defence may argue that the expedited schedule constrains the ability to obtain independent expert opinions, thereby affecting the adversarial balance.

Ultimately, the prosecution bears the burden of proving the accused’s guilt beyond reasonable doubt, and the acceptance of gait analysis and clothing as evidence will be assessed in light of whether they meet the threshold of relevance, reliability, and probative value without undue prejudice. If the court finds that the forensic methodology lacks sufficient scientific underpinning or that the acquisition of clothing violated procedural safeguards, it may deem the evidence inadmissible, thereby compelling the prosecution to rely on alternative proof such as eyewitness testimony or forensic DNA. Conversely, a finding that the gait analysis is scientifically valid and that the clothing seizure complied with statutory requirements could strengthen the prosecution’s narrative, potentially influencing the court’s assessment of intent and the degree of culpability attributed to the accused.
