IPC 84 → BNS 22: Unsound Mind

Quick Summary: IPC 84 vs BNS 22

The Bharatiya Nyaya Sanhita (BNS) 2023, in force since 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. IPC 84 (Unsound Mind) is among the offences re-enacted by the Bharatiya Nyaya Sanhita, which reorganises and renumbers the old Indian Penal Code while keeping the core ingredients intact. Unsound Mind now maps to BNS 22, and the position below reflects the current bare act.

What did IPC 84 cover?

IPC 84 dealt with unsound mind — act of a person of unsound mind. Until 30 June 2024, every FIR and criminal trial for this offence was registered and prosecuted under this provision of the Indian Penal Code 1860.

BNS 22: What changed in the new law?

Refers to 'mental illness' in broader legal context. From 1 July 2024, new complaints relating to unsound mind are filed under BNS Section 22, while cases registered earlier continue under the old IPC provision as per the saving clause of the BNS.

Practical implications for advocates, police & citizens

• Advocates: For unsound mind, cite the current provision BNS 22 rather than the repealed IPC 84 in all matters arising on or after 1 July 2024.
• Police officers: Register new unsound mind FIRs under BNS 22; procedure follows the BNSS.
• Law students & citizens: Use the IPC 84 to BNS 22 mapping when checking your position on unsound mind under the new law.
