Indian Criminal Procedure Law

Code of Criminal Procedure (CrPC) and Bharatiya Nagarik Suraksha Sanhita (BNSS)

An accessible guide to India's criminal procedure framework, including the transition from the Code of Criminal Procedure, 1973 to the Bharatiya Nagarik Suraksha Sanhita, 2023, and selected articles on limitation and public duties.

Updated: 9 October 2026

Overview of Criminal Procedure in India

The Code of Criminal Procedure, 1973 (CrPC) established procedures for investigation, arrest, bail, inquiry, trial, appeals and related criminal proceedings. From 1 July 2024, the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), Act 46 of 2023, replaced the CrPC as India's principal general criminal procedure statute, subject to its repeal and savings provisions and the operation of special laws.

Important legal transition: Section 531(1) of the BNSS repeals the CrPC. Under Section 531(2)(a), appeals, applications, trials, inquiries and investigations pending immediately before commencement continue under the CrPC as specified in that provision. The applicable procedural law must therefore be assessed in light of the date and nature of the proceeding.

The BNSS operates alongside the Bharatiya Nyaya Sanhita, 2023 (substantive criminal offences) and the Bharatiya Sakshya Adhiniyam, 2023 (law of evidence). These statutes serve different functions and should not be treated as interchangeable.

Criminal Procedure Articles and Legal Analysis

Limitation Period for Taking Cognizance of Offences: CrPC Sections 468 to 473

Learn how the limitation period for taking cognizance is determined, when it begins, how certain periods are excluded, the treatment of continuing offences and when delay may be condoned. The corresponding BNSS provisions are Sections 514 to 519.

Public Responsibility to Assist Magistrates and Police: CrPC Sections 37, 38 and 39

Understand the duty to provide reasonable assistance to Magistrates and police, assistance in execution of warrants directed to non-police persons and the duty to report specified offences. The corresponding BNSS provisions are Sections 31, 32 and 33.

Limitation for Taking Cognizance of Offences

Section 514 of the BNSS, corresponding broadly to Section 468 of the CrPC, places a time limit on courts taking cognizance of certain offences. The statutory periods are generally six months for offences punishable with fine only, one year where imprisonment does not exceed one year, and three years where imprisonment exceeds one year but does not exceed three years. The statutory rules, exceptions and relevant filing dates must be examined in each case.

Public Duties to Assist Magistrates and Police

BNSS Section 31 (earlier CrPC Section 37): A person must provide assistance reasonably demanded by a Magistrate or police officer in making or preventing escape from an authorised arrest, preventing or suppressing a breach of peace, or preventing attempted injury to public property.

BNSS Section 32 (earlier CrPC Section 38): Where a warrant is directed to a person other than a police officer, another person may assist its execution when the warrant-holder is nearby and acting to execute it.

BNSS Section 33 (earlier CrPC Section 39): Persons aware of the commission or intended commission of specified serious offences have a duty to give information as prescribed, subject to the statutory qualification concerning reasonable excuse. The exact offences listed in the BNSS should be consulted rather than assuming that the former CrPC list remains unchanged.
