IPC 144 → BNS 187: Unlawful Assembly

Quick Summary: IPC 144 vs BNS 187

The Bharatiya Nyaya Sanhita (BNS) 2023, which came into force on 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. Under the new criminal law framework, IPC Section 144 (Unlawful Assembly) is now mapped to BNS Section 187.

What did IPC 144 cover?

IPC 144 dealt with unlawful assembly — joining unlawful assembly armed with deadly weapon. Until 30 June 2024, every FIR and criminal trial relating to this offence in India was registered and prosecuted under this provision of the Indian Penal Code 1860.

BNS 187: What changed in the new law?

Clearer provisions for public order. From 1 July 2024, all new criminal complaints relating to unlawful assembly are filed under BNS Section 187. Cases registered before 1 July 2024 will, however, continue to be tried under the old IPC provisions as per the saving clause of the BNS.

Punishment under BNS 187

Practical implications for advocates, police & citizens

• Advocates: While drafting bail applications, vakalatnamas and written statements for offences registered after 1 July 2024, cite BNS 187 instead of IPC 144.
• Police officers: Use BNS 187 as the substantive offence in new FIRs; procedure is governed by the Bharatiya Nagarik Suraksha Sanhita (BNSS).
• Law students & citizens: For competitive exams, judicial services and general awareness, remember the IPC 144 ↔ BNS 187 mapping.
