IPC 43 → BNS 2(15): Illegal

Quick Summary: IPC 43 vs BNS 2(15)

The Bharatiya Nyaya Sanhita (BNS) 2023, in force since 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. IPC 43 (Illegal) 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. Illegal now maps to BNS 2(15), and the position below reflects the current bare act.

What did IPC 43 cover?

IPC 43 dealt with illegal — definition of 'illegal' and 'legally bound to do'. 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 2(15): What changed in the new law?

No major change. From 1 July 2024, new complaints relating to illegal are filed under BNS Section 2(15), while cases registered earlier continue under the old IPC provision as per the saving clause of the BNS.

• Law students & citizens: Use the IPC 43 to BNS 2(15) mapping when checking your position on illegal under the new law.
