Repeal and Savings
(1) The Indian Penal Code, 1860 is repealed. (2)-(4) This repeal doesn't affect the IPC's previous operation, anything already done under it, rights/privileges/obligations already acquired/incurred under it, or any penalty/proceeding/investigation/remedy relating to offences already committed under it - all such matters continue exactly as if the IPC hadn't been repealed. Anything done under the IPC is deemed done under this Sanhita's corresponding provisions. This section's specific mentions don't limit the General Clauses Act, 1897's general repeal-effect provisions.
This final section formally repeals the 163-year-old Indian Penal Code and replaces it with the BNS, while carefully preserving all rights, liabilities, and ongoing proceedings under the old law - ensuring the transition doesn't wipe out pending cases or create legal gaps for conduct that occurred before 1 July 2024.
This is why a crime committed under the old IPC before 1 July 2024 is still prosecuted based on the IPC's provisions and penalties (as they applied at the time), even though the IPC itself has now been formally repealed and replaced by the BNS - this section's savings clause exists specifically to prevent any gap or unfairness during the transition between the two codes.
