Overview
The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which replaced the Code of Criminal Procedure, 1973 as India’s criminal procedure statute, introduced a provision with no real precedent in the old Code: a statutory duty to bring forensic science to the crime scene in serious cases. This duty is contained in Section 176(3) of the BNSS, and it converts what was earlier a matter of investigating-officer discretion into a mandatory legal obligation, backed by a videography requirement intended to make the collection of evidence auditable. This article explains what Section 176(3) actually says, how it fits into the broader investigation procedure under Section 176, how at least one High Court has already engaged with it, and what has been reported about the practical challenge of rolling out this mandate in Uttar Pradesh.
Statutory Framework
Section 176 of the BNSS corresponds to Section 157 of the former Code of Criminal Procedure, 1973 and lays down the procedure an officer in charge of a police station must follow on receiving information of a cognisable offence. Sub-section (1) requires the officer to send a report to the jurisdictional Magistrate and to proceed to investigate — in person or through a subordinate officer — including, where necessary, taking measures for the discovery and arrest of the offender. Sub-section (2) requires the officer to record reasons in specified situations where he does not proceed to the spot himself.
Sub-section (3) is the new addition, and it is the operative provision for this article. It reads:
“On receipt of every information relating to the commission of an offence which is made punishable for seven years or more, the officer in charge of a police station shall, from such date, as may be notified within a period of five years by the State Government in this regard, cause the forensic expert to visit the crime scene to collect forensic evidence in the offence and also cause videography of the process on mobile phone or any other electronic device.”
The proviso that immediately follows addresses states or regions that lack the forensic infrastructure to comply:
“Provided that where forensic facility is not available in respect of any such offence, the State Government shall, until the facility in respect of that matter is developed or made in the State, notify the utilisation of such facility of any other State.”
Three elements of the text matter for understanding how the mandate actually applies:
- Threshold. The duty is triggered by offences “punishable for seven years or more” — a sentence-length test, not a list of named offences. It therefore sweeps in a wide range of serious crimes across the penal statutes, not only homicide or sexual offences.
- Two distinct duties. The officer in charge must (a) cause a forensic expert to physically visit the crime scene to collect forensic evidence, and (b) cause videography of that process on a mobile phone or other electronic device. Both duties travel together — the video record is meant to document that the forensic step actually happened, and how.
- Notified commencement. The obligation does not take effect everywhere from the date BNSS itself came into force. It becomes binding “from such date, as may be notified within a period of five years by the State Government.” In other words, each State Government has up to five years to notify the date from which the forensic-visit-and-videography duty is actually enforceable in that state, and — per the proviso — a state without adequate forensic facilities may, in the meantime, direct that another state’s facility be used.
What This Means in Practice
For an investigating officer, Section 176(3) means that a first information report for an offence carrying a sentence of seven years or more cannot, once the provision is operative in that state, be treated as a matter for the investigating officer’s discretion alone on the forensic side. A forensic expert’s visit to the scene — and a video record of that visit — becomes part of what a compliant investigation looks like.
For an accused person or a defence lawyer, this matters because crime-scene forensic evidence, and how it was collected, increasingly goes to the reliability of the prosecution’s case. Poor scene management, absence of forensic collection, or absence of the videography record can be raised as an investigative deficiency when the matter is contested at trial — the weight a court gives to such a lapse will still depend on the facts of each case, but the statute now gives that argument a clear textual anchor that did not exist under the old Code.
For the state, the provision creates an infrastructure obligation that runs alongside the legal one: a forensic expert has to actually be available to visit the scene, and someone has to be capable of producing the video record in a form that can be relied on later. That is the practical challenge discussed below.
Key Case Law
The judiciary has already begun to engage with Section 176(3) in the short period since BNSS came into force. In Suresh v. State of Kerala, the Kerala High Court (Justices Raja Vijayaraghavan V. and K.V. Jayakumar), in a judgment reported in late July 2025, set aside a murder conviction on the ground that the prosecution had failed to prove its case beyond reasonable doubt — the scene mahazar and site plan were found to be of little evidentiary value, and no scientific evidence had been collected during the investigation. Beyond deciding the appeal, the Bench went on to direct the state police to adopt the digital reforms brought in by the BNSS framework, including use of the “e-Sakshya” application for evidence documentation, and to ensure compliance with the forensic-expert and videography requirements for qualifying offences going forward. The Court directed that a copy of the judgment be forwarded to the State Police Chief and the Home Department. The case illustrates, from a High Court, the kind of investigative gap Section 176(3) is designed to close, and a court’s willingness to issue forward-looking directions on compliance even while deciding an individual appeal.
The Rollout Gap: What Has Been Reported in Uttar Pradesh
Because Section 176(3) only takes legal effect in a state from the date that state notifies, the on-the-ground picture is a mix of capacity-building already under way and gaps still being reported.
On the capacity-building side, Uttar Pradesh has been reported as deploying mobile forensic vans to bring evidence-collection capability directly to the crime scene rather than requiring samples to travel to a static lab — reported figures put this at three mobile forensic vans in larger districts and two in smaller ones. Separately, the Uttar Pradesh State Institute of Forensic Science (UPSIFS) has been running dedicated “Crime Scene Management” training batches for police officers; its fifth such batch, reported in July 2026, covered 94 officers over a six-week programme addressing scientific crime-scene management, evidence preservation, and cyber forensics.
At the same time, the underlying strain on forensic infrastructure that a mandate like Section 176(3) places pressure on is not new. A 2023 analysis of a Project 39A report on India’s forensic science system found that, across the state forensic science laboratories examined, roughly 40% of sanctioned scientific posts were vacant nationally — and that the State Forensic Science Laboratory in Lucknow had the highest vacancy rate found in that dataset, at 73%. That data predates BNSS’s commencement and should be read as background on capacity constraints rather than as a direct measure of current Section 176(3) compliance, but it explains why courts and commentators have flagged the gap between what the new provision demands and what existing forensic infrastructure can deliver. The Calcutta High Court, for instance, has separately observed that the new forensic-evidence requirement could put “immense pressure” on central and state forensic laboratories tasked with analysing samples, particularly for DNA analysis.
Taken together, the reporting suggests a mandate that is real and increasingly being acted on — through mobile vans and dedicated training — but whose full, uniform rollout across every police station in Uttar Pradesh remains a work in progress, consistent with the five-year notification window the statute itself allows.
Practical Points
- Section 176(3) applies to offences punishable with seven years or more, and imposes two linked duties: a forensic expert’s visit to the crime scene, and videography of that process.
- The duty becomes legally binding in a given state only from the date that state notifies, within a five-year window from the relevant commencement date — it is not automatically enforceable everywhere from day one.
- Where local forensic facilities are unavailable, the proviso allows a state to rely on another state’s facility until its own capacity is developed.
- Courts have already begun issuing compliance directions where investigations fall short of the standard the new provision sets, as in the Kerala High Court’s judgment discussed above.
- Reported infrastructure measures in Uttar Pradesh — mobile forensic vans and UPSIFS training batches — indicate active capacity-building, even as broader forensic-lab staffing constraints reported in earlier data illustrate why full rollout takes time.
Takeaway
Section 176(3) of the BNSS marks a genuine shift in Indian criminal procedure: forensic examination of the crime scene, for offences carrying a sentence of seven years or more, is no longer optional good practice but a statutory duty, documented through mandatory videography. Its practical bite, however, depends on state-level notification and on forensic infrastructure that can actually deliver a qualified expert to the scene. Uttar Pradesh’s reported measures — mobile forensic vans and dedicated crime-scene-management training — reflect the scale of the build-out this provision requires, and reported capacity constraints in the wider forensic system underline why the statute itself allows up to five years for states to bring the mandate fully into force.
