IPC 123 → BNS 150: Concealing War Design

Quick Summary: IPC 123 vs BNS 150

The Bharatiya Nyaya Sanhita (BNS) 2023, in force since 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. IPC 123 (Concealing War Design) 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 150, 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acts that endanger the nation, so concealing war design must now be read through the new framework rather than the repealed IPC 123.

What did IPC 123 cover?

IPC 123 dealt with concealing war design — concealing with intent to facilitate design to wage war. 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 150: What changed in the new law?

No major change. From 1 July 2024, new complaints relating to concealing war design are filed under BNS Section 150, while cases registered earlier continue under the old IPC provision as per the saving clause of the BNS.

Punishment under BNS 150

Same - Up to 10 years

Practical implications for advocates, police & citizens

• Advocates: Charges for concealing war design in this group are grave, typically non-bailable Sessions matters — confirm the required prior sanction and frame them under BNS 150 rather than the repealed IPC 123.
• Police officers: Route a concealing war design investigation through the prescribed sanctioning authority and cite BNS 150 in the FIR; procedure follows the BNSS.
• Law students & citizens: Because concealing war design in this group carries severe punishment, never rely on the old IPC 123 number when checking your position under the new law.
