Code of Criminal Procedure, 1973 · Chapter XII: Information to the Police and Their Powers to Investigate

Section 155: Information as to non-cognizable cases and investigation of such cases

The Code of Criminal Procedure, 1973 was repealed and replaced by the Bharatiya Nagarik Suraksha Sanhita, 2023 from 1 July 2024. It still applies to matters and proceedings from before that date, as the repealing law provides.

Now in the BNSS section 174 (Information as to non-cognizable cases and investigation of such cases)

In plain words

For a non-cognizable offence, the police station officer must enter the substance of the information in the prescribed book and refer the informant to the Magistrate. Police cannot investigate a non-cognizable case without a Magistrate's order.

  • Once ordered, the police have the same investigation powers as in a cognizable case, except arrest without warrant.
  • A case involving at least one cognizable offence is treated as a cognizable case.

Official text

(1) When information is given to an officer in charge of a police station of the commission within the limits of such station of a non-cognizable offence, he shall enter or cause to be entered the substance of the information in a book to be kept by such officer in such form as the State Government may prescribe in this behalf, and refer the informant to the Magistrate.

(2) No police officer shall investigate a non-cognizable case without the order of a Magistrate having power to try such case or commit the case for trial.

(3) Any police officer receiving such order may exercise the same powers in respect of the investigation (except the power to arrest without warrant) as an officer in charge of a police station may exercise in a cognizable case.

(4) Where a case relates to two or more offences of which at least one is cognizable, the case shall be deemed to be a cognizable case, notwithstanding that the other offences are non-cognizable.

Corresponding sections were matched by comparing the wording of both official texts, and for the IPC and BNS, also against a published correspondence table. Wording, punishments and structure often changed, so read both sections before relying on the match.
