The Code of Criminal Procedure, commonly called Criminal Procedure Code (CrPC), was the main legislation on procedure for administration of substantive criminal law in India. It was enacted in 1973 and came into force on 1 April 1974. It provides the machinery for the investigation of crime, apprehension of suspected criminals, collection of evidence, determination of guilt or innocence of the accused person and the determination of punishment of the guilty. It also deals with public nuisance, prevention of offences and maintenance of wife, child and parents.
On 11 August 2023, a Bill to replace the CrPC with the Bharatiya Nagarik Suraksha Sanhita (BNSS) was introduced in the Lok Sabha. On 26 December 2023, it was replaced with Bharatiya Nagarik Suraksha Sanhita (BNSS).
