Quick answer
Section 176(3) of the B.N.S.S. requires the officer in charge of a police station, on receiving information about an offence punishable for seven years or more, to cause a forensic expert to visit the crime scene to collect forensic evidence and to cause videography of the process on a mobile phone or any other electronic device. The duty applies from the date the State Government notifies, which must be within five years. If a State does not yet have the forensic facility, it must notify the use of another State's facility until its own is developed.
The law
Section 176 B.N.S.S. (Procedure for investigation) sets out how the police begin an investigation into a cognizable offence. Sub-section (1) requires the officer in charge to send a report to the Magistrate and to go to the spot, or depute a subordinate, to investigate the facts. Sub-section (3), a new provision, adds a scientific step for serious offences.
Its main features are:
- Trigger: information relating to an offence "made punishable for seven years or more".
- Duty-holder: the officer in charge of the police station.
- Two duties: (a) cause a forensic expert to visit the crime scene to collect forensic evidence; and (b) cause videography of the process on a mobile phone or any other electronic device.
- Start date: from the date notified by the State Government, within a period of five years.
- Proviso: where forensic facility is not available for such an offence, the State Government shall notify the use of another State's facility until its own facility is developed.
The same section also makes a related change for rape cases: under the second proviso to Section 176(1), the victim's statement is recorded at her residence or a place of her choice, as far as practicable by a woman police officer, and may also be recorded through audio-video electronic means including a mobile phone.
Why it matters
- Better evidence: blood, fingerprints, tool marks and similar traces are collected by an expert rather than left to chance.
- Transparency: the video shows how the evidence was collected, which helps the court judge whether it was handled properly.
- Less dependence on eyewitnesses: scientific evidence supports, but does not replace, oral evidence.
Old law and new law
| Point | Section 157 CrPC (old law) | Section 176 B.N.S.S. |
|---|---|---|
| Report to Magistrate and visit to the spot | Yes | Yes |
| Forensic expert to visit the crime scene | No such duty | Yes, for offences punishable for seven years or more (Section 176(3)) |
| Videography of evidence collection | No such duty | Yes, on mobile phone or other electronic device |
| Commencement | Not applicable | From the date notified by each State Government, within five years |
Example
Zoya reports that two men broke into her shop at night, threatened to beat her and took the cash. Robbery is punishable under Section 309(4) B.N.S. with rigorous imprisonment up to ten years, so it crosses the seven-year threshold. If Section 176(3) has been brought into force in Zoya's State, the officer in charge must have a forensic expert visit the shop to lift fingerprints, collect bloodstains and examine the broken lock, and the whole process must be video-recorded on a mobile phone or other device.
Current-law note
Section 176(3) operates only from the date each State Government notifies. Whether it is already in force in a particular State must be checked in that State's official notification. For the investigation chapter as a whole, see B.N.S.S.: Complete Notes.
Exam point
Section 176(3) B.N.S.S.: for offences punishable for seven years or more, a forensic expert must visit the crime scene and the process must be videographed, from a date notified by the State Government within five years.
