IPC 138 → BNS 166: Insubordination

Quick Summary: IPC 138 vs BNS 166

The Bharatiya Nyaya Sanhita (BNS) 2023, in force since 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. IPC 138 (Insubordination) sits among the IPC's offences against the State and the armed forces — the group the Bharatiya Nyaya Sanhita redrew more heavily than almost any other. Renumbered as BNS 166, the conduct is recast around the sovereignty, unity and integrity of India, with the colonial sedition offence replaced by a distinct provision targeting acts that endanger the nation, so insubordination must now be read through the new framework rather than the repealed IPC 138.

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 for this offence 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, new complaints relating to insubordination are filed under BNS Section 166, while cases registered earlier continue under the old IPC provision as per the saving clause of the BNS.

Punishment under BNS 166

Same - Up to 6 months

Practical implications for advocates, police & citizens

• Advocates: Charges for insubordination in this group are grave, typically non-bailable Sessions matters — confirm the required prior sanction and frame them under BNS 166 rather than the repealed IPC 138.
• Police officers: Route a insubordination investigation through the prescribed sanctioning authority and cite BNS 166 in the FIR; procedure follows the BNSS.
• Law students & citizens: Because insubordination in this group carries severe punishment, never rely on the old IPC 138 number when checking your position under the new law.
