IPC Section 149: Liability of Every Member of an Unlawful Assembly - BNS Section 190
Section 149 of the Indian Penal Code, 1860 explains when members of an unlawful assembly can be held responsible for an offence committed by another member in pursuit of the assembly's common object. The corresponding provision in the Bharatiya Nyaya Sanhita, 2023 is Section 190.
Text and meaning of IPC Section 149
If an offence is committed by any member of an unlawful assembly in prosecution of the common object of that assembly, or such as the members of that assembly knew to be likely to be committed in prosecution of that object, every person who, at the time of the committing of that offence, is a member of the same assembly, is guilty of that offence.
This is the substantive rule stated in the former IPC Section 149. It attributes responsibility for a qualifying offence to members of the same unlawful assembly even where a particular member did not personally perform the criminal act. The required statutory conditions must still be proved.
Current law: BNS Section 190
The Bharatiya Nyaya Sanhita, 2023 (Act 45 of 2023) came into force on 1 July 2024, replacing the IPC for offences governed by the new enactment. BNS Section 190, titled Every member of unlawful assembly guilty of offence committed in prosecution of common object, substantially retains the principle previously expressed in IPC Section 149.
BNS Section 189(1) defines an unlawful assembly: an assembly of five or more persons whose common object falls within any of the prohibited categories specified there. An assembly initially lawful can subsequently become unlawful. The nature of the common object, and whether an individual knowingly joined or continued as a member, are material questions.
For incidents occurring before 1 July 2024, the applicable substantive law and any savings or transitional provisions must be examined. The date of the alleged conduct is important; the IPC label should not simply be substituted in every pending matter.
Essential ingredients of common-object liability
- Unlawful assembly: There must be an assembly of at least five persons meeting the definition under IPC Section 141 or BNS Section 189(1), as applicable.
- Membership: The accused must have been a member of that unlawful assembly when the underlying offence was committed.
- Qualifying offence: An offence must have been committed by a member of that assembly.
- Connection to the common object: The offence must have been committed in prosecution of the assembly's common object, or it must have been an offence the members knew was likely to be committed in pursuing that object.
- Proof: The prosecution must establish the necessary facts beyond reasonable doubt; membership and common object are assessed from the evidence and surrounding circumstances.
What does "common object" mean?
A common object is the shared objective that brings the assembly within the statutory definition of an unlawful assembly. It can be inferred from conduct, weapons, words, the nature of the gathering, actions before and during the incident, and other proved circumstances. It need not be evidenced by a formal agreement. However, mere presence at the scene or association with some participants does not automatically prove membership or the required shared object.
The two limbs of Section 149 are distinct: the offence may be committed in prosecution of the common object, or the members may have known that the offence was likely to occur while pursuing it. The latter is a knowledge requirement, not simply a finding that an offence was remotely possible.
Punishment under IPC 149 and BNS 190
Neither IPC Section 149 nor BNS Section 190 provides a separate fixed term of imprisonment or fine. Liability is for the underlying offence established through the common-object rule, and the punishment follows the provision governing that offence. Whether an offence is bailable or non-bailable, cognizable or non-cognizable, and which court may try it likewise depends on the substantive offence and the applicable procedural law.
| Legal issue | Former IPC | Current BNS |
|---|---|---|
| Definition of unlawful assembly | Section 141 | Section 189(1) |
| Common-object liability | Section 149 | Section 190 |
| Definition of rioting | Section 146 | Section 191(1) |
| Punishment for rioting | Section 147 | Section 191(2) |
| Rioting armed with deadly weapon | Section 148 | Section 191(3) |
Practical illustrations
Example 1: Offence in pursuit of the common object
Six persons assemble with a common object of forcibly dispossessing someone. During the action, one member commits a related offence to carry out that object. If the legal requirements are established, the other members may also be liable for that offence under the common-object provision.
Example 2: Unexpected independent act
One participant commits an offence entirely outside the common object and not known by the other members to be likely in its pursuit. Liability for that separate offence does not automatically attach to everyone merely because they were present.
Difference between Section 149 and common intention
Common-object liability under IPC Section 149 / BNS Section 190 concerns membership of an unlawful assembly of five or more and the statutory connection between an offence and the common object or knowledge. Common-intention liability under IPC Section 34 / BNS Section 3(5) is a separate doctrine involving acts done in furtherance of a common intention. The requirements are not interchangeable.
Frequently asked questions
What is Section 149 IPC?
IPC Section 149 makes each member of an unlawful assembly liable for an offence committed by a member in prosecution of its common object, or one the members knew was likely in pursuing that object, provided the person was a member when the offence occurred.
Which BNS section replaces IPC Section 149?
Section 190 of the Bharatiya Nyaya Sanhita, 2023 substantially carries forward the common-object liability rule of IPC Section 149 for offences governed by the BNS.
Must every member personally commit violence?
No. Personal commission of the underlying act is not invariably necessary, but the prosecution must establish the required membership and connection to the common object or knowledge under the statute.
Does Section 149 prescribe a separate prison term?
No. It is a rule of constructive criminal liability. Punishment depends on the underlying offence established against the accused, not a standalone sentence under Section 149.
Is mere presence at the scene enough?
No. Mere presence among a crowd does not by itself establish knowing membership of an unlawful assembly or liability for an offence under the common-object rule.
