IPC 138 → BNS 166: Insubordination

Quick Summary: IPC 138 vs BNS 166

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 138 (Insubordination) is now mapped to BNS Section 166.

What did IPC 138 cover?

IPC 138 dealt with insubordination — abetment of act of insubordination by soldier, sailor or airman. 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 166: What changed in the new law?

No major change. From 1 July 2024, all new criminal complaints relating to insubordination are filed under BNS Section 166. 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 166

Same - Up to 6 months

Practical implications for advocates, police & citizens

• Advocates: While drafting bail applications, vakalatnamas and written statements for offences registered after 1 July 2024, cite BNS 166 instead of IPC 138.
• Police officers: Use BNS 166 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 138 ↔ BNS 166 mapping.
