BNS Section 51 Explained: Liability of Abettor When One Act Is Abetted and a Different Act Is Done

Adv. Kuldeep Kumar June 23, 2026 5 min read

Section Overview

Section Number: 51

Section Title: Liability of Abettor When One Act Is Abetted and a Different Act Is Done

Act: Bharatiya Nyaya Sanhita, 2023 (BNS)

Status: Active

Applicability: This section applies when a person abets the commission of a particular act, but the person carrying out the offence commits a different act which is a probable consequence of the original abetment.

Section Explanation

Simple Explanation (Plain English/Hinglish)

BNS Section 51 ka basic principle yeh hai ki agar koi vyakti kisi doosre vyakti ko ek specific crime karne ke liye instigate, encourage ya help karta hai, lekin actual mein doosra vyakti thoda alag crime kar deta hai, to abettor phir bhi liable ho sakta hai.

Lekin liability tabhi hogi jab jo act ultimately hua hai, woh original abetment ka probable ya foreseeable consequence ho.

Example ke liye, agar A, B ko kisi vyakti ko simple injury pahunchane ke liye encourage karta hai aur B attack ke dauran grievous hurt kar deta hai, to circumstances ke hisab se A bhi us grievous hurt ke liye liable ho sakta hai.

Legal Definition

The principle embodied in BNS Section 51 provides that where an act is abetted and a different act is done, the abettor is liable for the act done in the same manner and to the same extent as if he had directly abetted that act, provided the act committed was a probable consequence of the abetment.

Practical Interpretation

Courts generally examine:

  • Nature of the original abetment

  • Intention of the abettor

  • Foreseeability of the final act

  • Knowledge possessed by the abettor

  • Circumstances surrounding the offence

  • Relationship between the original act and the final act

If the final act is completely unrelated to the original abetment, liability may not arise.

Punishment & Legal Classification

Punishment: Depends upon the offence actually committed.

Bailable / Non-bailable: Depends on the underlying offence.

Cognizable / Non-cognizable: Depends on the offence committed.

Compoundable: Depends on the principal offence.

Triable By: The court having jurisdiction over the substantive offence committed.

Important Note

Section 51 itself does not prescribe an independent punishment. The punishment is linked to the offence for which liability is extended through abetment.

IPC ↔ BNS Mapping

IPC Section: Section 111 of the Indian Penal Code, 1860

BNS Equivalent: Section 51 of Bharatiya Nyaya Sanhita, 2023

Status: Replaced under BNS

The legal principle remains substantially similar to IPC Section 111 and therefore earlier judicial precedents continue to have persuasive value.

Real-Life Examples

Example 1: Assault Leading to Grievous Injury

A encourages B to slap C during a dispute.

Instead of merely slapping C, B severely beats him and causes grievous injuries.

If grievous injury was a probable consequence of the instigation, A may also be held liable.

Example 2: Property Damage Resulting in Fire

A asks B to damage a rival's shop.

While damaging the shop, B sets fire to the property causing extensive destruction.

If such destruction was a foreseeable consequence, A can be held responsible.

Example 3: Unlawful Assembly

A encourages a group to intimidate another group.

During the confrontation, members of the group seriously injure a victim.

Where such violence was reasonably foreseeable, A may incur criminal liability.

Landmark Judgments

Case Name: Queen v. Mohit

Court: Calcutta High Court

Key Takeaway:

The Court recognized that an abettor can be held responsible not only for the exact act instigated but also for acts that naturally and probably flow from the original abetment.

Case Name: Jamuna Singh v. State of Bihar

Court: Supreme Court of India

Key Takeaway:

The Supreme Court discussed principles of abetment and clarified that criminal liability depends on intention, participation, and the connection between the conduct of the abettor and the resulting offence.

Case Name: Chitresh Kumar Chopra v. State (NCT of Delhi)

Court: Supreme Court of India

Key Takeaway:

The Court elaborated on the concept of instigation and emphasized the importance of examining facts and circumstances while determining liability for abetment.

Legal Insights

When Is This Section Applied?

BNS Section 51 is commonly applied when:

  • A person instigates another to commit an offence.

  • The final offence differs from the original plan.

  • The resulting act is reasonably foreseeable.

  • There is a direct connection between abetment and commission.

  • The prosecution can establish probable consequences.

Common Misuse Scenarios

Some common issues include:

  1. Attempting to impose liability for completely unrelated acts.

  2. Treating every consequence as foreseeable.

  3. Ignoring the actual intention of the abettor.

  4. Expanding criminal liability beyond reasonable limits.

Courts therefore carefully evaluate evidence before applying Section 51.

Defenses Available

An accused may rely upon several defenses:

  • Lack of intention

  • No instigation or assistance

  • Absence of knowledge

  • Independent act by the principal offender

  • Unforeseeable consequences

  • No causal connection between abetment and offence

If the act ultimately committed was entirely outside the scope of the original abetment, the defense may succeed.
