Mandatory Forensic Investigation — BNSS Section 176(3) (New Provision)

In India, Section 176(3) of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) requires police, for offences punishable with seven years or more, to have a forensic expert visit the crime scene and to videograph the process. It applies from a date each State notifies within five years. Section 157 CrPC, its predecessor, had no such duty.

What changed

Section 176 BNSS as a whole replaces s.157 CrPC. Sub-section by sub-section:

• s.176(1), main clause — Minor edit. Identical to s.157(1) except that "empowered under section 156" became "empowered under section 175".
• First proviso, clauses (a) and (b) — Minor edit. The same words (no need to go in person where the case "is not of a serious nature"; no investigation where there is "no sufficient ground"). Clause (b) now ends with a colon instead of a full stop.
• Second proviso (statement of a rape victim) — Expanded. It is still recorded at the victim's residence or place of her choice, as far as practicable by a woman police officer. The BNSS adds that "such statement may also be recorded through any audio-video electronic means including mobile phone".
• s.176(2) — Modified. "the proviso" became "the first proviso". "his reasons for not fully complying" became "the reasons for not fully complying … by him". New words require the officer to "forward the daily diary report fortnightly to the Magistrate". The notice to the informant under clause (b) is now "in such manner as may be prescribed by rules made by the State Government". The CrPC words stating what is notified — "the fact that he will not investigate the case or cause it to be investigated" — are not in the BNSS text.
• s.176(3) — New. The forensic-expert visit and videography duty for offences "made punishable for seven years or more", from the State-notified date.
• Proviso to s.176(3) — New. A mandatory ("shall") notification of another State's facility where a State lacks one.

Statutory text (relevant extract)

Section 157(1) CrPC — extract (original-PDF text):

(1) If, from information received or otherwise, an officer in charge of a police station has reason to suspect the commission of an offence which he is empowered under section 156 to investigate, he shall forthwith send a report of the same to a Magistrate … and shall proceed in person, or shall depute one of his subordinate officers … to proceed, to the spot, to investigate the facts and circumstances of the case …

Section 176(3) BNSS and proviso — full text (Gazette):

(3) 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:

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.

How it works — the elements

1. Trigger — information of an offence. The duty arises "on receipt of every information relating to the commission of an offence". It is not limited to FIRs under s.173, and it is not limited to BNS offences.
2. Threshold — "made punishable for seven years or more". The text does not say whether the maximum or the minimum term is the measure. Murder (BNS s.103(1): death or imprisonment for life) and rape (BNS s.64(1): not less than ten years, up to life) meet either measure. Voluntarily causing grievous hurt under BNS s.117(2) is punishable with imprisonment "which may extend to seven years". On a reading that looks to the maximum, it falls within s.176(3) — and outside the "less than seven years" band of s.173(3). The two provisions use the same "made punishable for" formula, and the boundary at seven years is shared.
3. Timing — the State's notified date. The officer's duty operates "from such date, as may be notified within a period of five years by the State Government". Until a State notifies, the sub-section imposes no duty on officers in that State. The text does not fix the starting point of the five years.
4. The act — cause a forensic expert to visit. The officer in charge must "cause the forensic expert to visit the crime scene to collect forensic evidence in the offence". The duty is to cause the visit; the collection is the expert's.
5. The record — videography. The officer must "also cause videography of the process on mobile phone or any other electronic device". Section 2(1)(a) BNSS defines "audio-video electronic means" to include recording of "processes of identification, search and seizure or evidence".
6. Fallback — another State's facility. Where a forensic facility "is not available in respect of any such offence", the State Government "shall" notify use of another State's facility until its own is developed.

What this means in practice

For investigating officers. First establish whether your State has notified its s.176(3) date; the sub-section does not operate before it. Where it applies, record in the case diary when the information was received, when the forensic expert was requested, and when the expert visited. Keep the videography file with its device details. If an electronic device is seized, the police report must state "the sequence of custody in case of electronic device" (s.193(3)(i), clause (i)). Searches and seizures themselves must be recorded through audio-video electronic means and the recording forwarded to the Magistrate without delay (s.105; s.185(2) proviso).

For prosecutors. Put the forensic expert's report and the videography on the record, together with evidence of how samples were sealed, stored and dispatched. Rahul (below) shows how a gap of days between seizure and dispatch, unexplained, can leave the court unable to rule out tampering.

For defence counsel. Ask three questions in sequence. Had the State notified its s.176(3) date before the information was received? Does the offence charged meet "seven years or more"? Was a forensic expert caused to visit and was the process videographed? Section 176(3) states no consequence for non-compliance, so the point is ordinarily one of weight and reliability, made through cross-examination on the gaps. It is not a ground of automatic exclusion found in the text.

For victims and families. For an offence in the threshold, the sub-section contemplates a forensic visit and a video record of it once the State's date applies. Under s.193(3)(ii), the informant or victim is entitled to a progress update within ninety days. That is a natural point to ask whether s.176(3) was complied with.

For State governments. Two duties are in the text: notify a date within the five-year window, and, where a forensic facility is unavailable for an offence, notify use of another State's facility ("shall").

Judgments that still matter

No Supreme Court judgment construing s.176(3) itself was located for this page. The judgments below, decided under the CrPC and the Evidence Act, address the problems the sub-section is aimed at. Their bearing on s.176(3) is stated as a reading.

Dayal Singh v. State of Uttaranchal, [2012] 10 S.C.R. 157 (2012 INSC 317), 3 August 2012 (Swatanter Kumar and Fakkir Mohamed Ibrahim Kalifulla JJ.). The Court examined deliberate lapses by the investigating officer and the doctor who conducted the post-mortem. It held that both "are obliged to be diligent, truthful and fair", that "A default or breach of duty, intentionally or otherwise, can sometimes prove fatal to the case of the prosecution", and that an investigating officer "is completely responsible and answerable for the manner and methodology adopted" (para 16). It also approved the principle that it "would not be right in acquitting an accused person solely on account of the defect" in investigation (para 27). The conviction was upheld, and directions issued for action against the officers. Bearing on s.176(3): on a reading, this is the framework for a court faced with a missing forensic visit or videography. Such a lapse is weighed with the rest of the evidence; it is neither ignored nor automatically fatal.

Dharam Deo Yadav v. State of U.P., [2014] 11 S.C.R. 650 (2014 INSC 265), 11 April 2014 (K.S. Radhakrishnan and A.K. Sikri JJ.; opinion of Radhakrishnan J.). In a circumstantial-evidence murder case resting partly on DNA identification of a skeleton, the Court said: "Crime scene has to be scientifically dealt with without any error". It added that forensic science "plays a pivotal role" and that the investigating officer must guard against contamination during "collection, packing and forwarding" (para 25). It accepted the DNA evidence, noting that reliability "depends on the quality control and quality assurance procedures in the laboratory" (para 34). The conviction stood; the death sentence was commuted (paras 36–37). Bearing on s.176(3): the sub-section makes an expert's presence at collection a statutory step for serious offences, which on a reading is aimed at the crime-scene handling the Court emphasised.

Shafhi Mohammad v. State of Himachal Pradesh, [2018] 3 S.C.R. 1096, order of 3 April 2018 (Adarsh Kumar Goel and R.F. Nariman JJ.). Acting on a Ministry of Home Affairs expert committee report, the Court agreed "that videography of crime scene during investigation is of immense value in improving administration of criminal justice" (para 9). It approved a centrally driven, phased plan of action (para 10). It directed the Ministry to set up a Central Oversight Body, with crime-scene videography to be introduced "at least at some places" in a first phase by 15 July 2018 (para 11). Bearing on s.176(3): the order was an administrative, phased programme. On a reading, s.176(3) moves crime-scene videography for serious offences from that programme into the statute, again on a State-by-State timetable.

Rahul v. State of Delhi, Ministry of Home Affairs, [2022] 9 S.C.R. 1129 (2022 INSC 1176), 7 November 2022 (three judges: U.U. Lalit CJI, S. Ravindra Bhat and Bela M. Trivedi JJ.; opinion of Trivedi J.). Samples seized on 14 and 16 February 2012 were sent for DNA examination on 27 February 2012 and meanwhile lay in the police station's malkhana. The Court held that "the possibility of tampering with the samples collected also could not be ruled out". It found that neither lower court had examined the basis of the DNA findings or whether the techniques were reliably applied (paras 31–32). The accused were acquitted (para 36). Bearing on s.176(3): on a reading, an expert-led collection with a video record is the kind of evidence that answers the gap on which this acquittal turned. The sub-section does not itself regulate storage and dispatch, so the chain after collection still has to be proved.

Which law applies to your case

The BNSS came into force on 1 July 2024. Section 531(2)(a) BNSS continues any investigation pending immediately before that date under the CrPC "as if this Sanhita had not come into force". On a reading, s.176(3) therefore does not govern such investigations. For investigations begun on or after 1 July 2024, the duty still applies only from the date the relevant State notifies. See which law applies to an offence before 1 July 2024.

Frequently asked questions

Which offences require a forensic expert visit under Section 176(3) BNSS? Section 176(3) BNSS applies on receipt of information of "an offence which is made punishable for seven years or more". It is framed by reference to punishment, not a list, and is not confined to offences under the Bharatiya Nyaya Sanhita, 2023. Murder under BNS s.103(1) (death or imprisonment for life) and rape under BNS s.64(1) (not less than ten years, up to imprisonment for life) fall within it on any measure.

Is Section 176(3) BNSS in force in every State? Not automatically. The duty applies "from such date, as may be notified within a period of five years by the State Government in this regard", so it bites in a State only once that State's notification takes effect. The sub-section does not say from what date the five years run. Whether a particular State has notified its date must be checked in that State's own Gazette; this page has not verified any State notification.

Did the CrPC have an equivalent of Section 176(3)? No. Section 176 BNSS replaces Section 157 CrPC, and sub-sections (1) and (2) largely re-enact Section 157. Section 157 contained no requirement to cause a forensic expert to visit the crime scene or to videograph the collection of forensic evidence; sub-section (3) and its proviso are new.

What exactly must be videographed under Section 176(3)? The officer in charge must "cause videography of the process on mobile phone or any other electronic device". Read with the rest of the sub-section, "the process" is the forensic expert's visit to the crime scene to collect forensic evidence. Separate BNSS provisions require audio-video recording of searches and seizures (Sections 105 and 185(2) proviso).

What if a State has no forensic laboratory? The proviso to Section 176(3) BNSS says 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". The proviso uses "shall", not "may"; there is no Section 176(4).

Does non-compliance with Section 176(3) make the evidence inadmissible? Section 176(3) does not state a consequence for non-compliance. Under the CrPC, the Supreme Court in Dayal Singh (2012) said a court should not acquit solely because of a defect in investigation, while noting that a flagrant default can prove fatal to the prosecution. On a reading, a missing forensic visit or videography goes to the weight and reliability of the evidence rather than automatically excluding it.

Does Section 176(3) apply to an investigation that began before 1 July 2024? On a reading of Section 531(2)(a) BNSS, no. That clause requires an investigation pending immediately before the Sanhita came into force to be continued under the CrPC "as if this Sanhita had not come into force", and the CrPC had no forensic-visit duty. Even for later investigations, the duty applies only from the date the State notifies.
