Chapter XXIA of the C.R.P.C. was incorporated in the year:

Chapter XXIA was inserted by section 4 of the Criminal Law (Amendment) Act 2005, which was enacted as Act 2 of 2006 and brought into force on 5 July 2006. Consequently 2006 is the year of incorporation into the operative CrPC. The 2005 in its short title must not be confused with the enactment and commencement year.

Current law: BNSS has applied since 1 July 2024, subject to section 531 preserving the CrPC for proceedings pending immediately before commencement. BNSS Chapter XXIII, sections 289–300, now governs plea bargaining for proceedings under that Sanhita; the historical incorporation year remains 2006.
