Common questions
What does BNSS section 176(3) require at crime scenes?+
It mandates that a forensic science laboratory team must visit the scene of any offence punishable with seven or more years of imprisonment. This is a legal requirement, not optional. The team collects evidence and videographs the scene as part of systematic crime scene management.
How does this differ from the old law?+
Under the previous CrPC, forensic team visits to crime scenes were discretionary. BNSS section 176(3) made them mandatory for serious offences, marking a structural shift toward consistent professional evidence collection across all jurisdictions.
Which crimes trigger this requirement?+
Any offence punishable with seven years or more imprisonment qualifies. Examples include arson cases (under BNS sections 324-326) and offences under the Explosive Substances Act 1908. The threshold focuses on serious crimes where forensic expertise is critical.
