IPC section 84 in the BNS

IPC 84BNS 22

IPC section 84, “Act of a person of unsound mind”, is now BNS section 22 of the Bharatiya Nyaya Sanhita, 2023, in force from 1 July 2024.

What changed

From IPC 84 to BNS 22

The words are the same as in the IPC, apart from “Sanhita” for the Act’s own name and the new numbers of the sections it refers to.

The official text

Old and new, side by side

Indian Penal Code, 1860

Section 84 Act of a person of unsound mind

Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law.

Bharatiya Nyaya Sanhita, 2023

Section 22 Act of a person of unsound mind

Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law.

The texts are India Code’s. The amendment markers and footnotes of the official print are left out, so the old section reads as it stood when it was repealed; State amendments are not shown. The PDFs linked below carry the full history.

Old law or new?

Which one applies to a case

The BNS repealed the IPC from 1 July 2024 (section 358(1)). The repeal does not reach back: under section 358(2), penalties and punishments incurred for offences committed against the IPC still stand, and proceedings for them may be started, continued and enforced as if the IPC had not been repealed. An act done before 1 July 2024 is therefore dealt with under the IPC section; an act done on or after that date, under the BNS.
