IPC 507 → BNS 351(4): Anonymous Intimidation

Quick Summary: IPC 507 vs BNS 351(4)

The Bharatiya Nyaya Sanhita (BNS) 2023, in force since 1 July 2024, has replaced the colonial-era Indian Penal Code (IPC) 1860. IPC 507 (Anonymous Intimidation) falls in the IPC's offences relating to marriage, reputation and intimidation — offences relating to marriage, cruelty by a husband or his relatives, defamation, and criminal intimidation or insult. Retained by the BNS as BNS 351(4), several such offences are non-cognizable or compoundable, which changes how anonymous intimidation is pursued.

What did IPC 507 cover?

IPC 507 dealt with anonymous intimidation — criminal intimidation by an anonymous communication. 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 351(4): What changed in the new law?

No major change. From 1 July 2024, new complaints relating to anonymous intimidation are filed under BNS Section 351(4), while cases registered earlier continue under the old IPC provision as per the saving clause of the BNS.

Punishment under BNS 351(4)

Same - Up to 2 years extra

Practical implications for advocates, police & citizens

• Advocates: For anonymous intimidation, check cognizability and whether the offence is compoundable before advising; the substantive provision is now BNS 351(4), not IPC 507.
• Police officers: Confirm whether the anonymous intimidation offence is cognizable before acting, and cite BNS 351(4) where an FIR is registered.
• Law students & citizens: Some offences in this group, including anonymous intimidation, can only be pursued on the complaint of the aggrieved person — know whether yours is cognizable.
