Indian Penal Code, 1860 · Chapter VIII: Of Offences against the Public Tranquillity

Section 149: Every member of unlawful assembly guilty of offence committed in prosecution of common object

The Indian Penal Code, 1860 was repealed and replaced by the Bharatiya Nyaya Sanhita, 2023 from 1 July 2024. It still applies to matters and proceedings from before that date, as the repealing law provides.

Now in the BNS section 190 (Every member of unlawful assembly guilty of offence committed in prosecution of common object)

In plain words

If a member of an unlawful assembly commits an offence in pursuing the common object, or one the members knew was likely to be committed in pursuing it, every person who is a member at that time is guilty of that offence.

Official text

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.

Understanding this section

Section 149 makes every member of an unlawful assembly guilty of an offence committed by any one member, if it was committed in prosecution of the assembly's common object, or was an offence the members knew was likely to be committed in prosecuting that object. It is constructive liability: you can be convicted of murder without striking a blow, simply because you were part of the assembly.

Ingredients

  • An unlawful assembly: five or more persons with a common object listed in section 141.
  • An offence committed by a member of that assembly.
  • The offence was committed in prosecution of the common object, or was one the members knew was likely to be committed in prosecution of it.
  • The accused was a member of the assembly at the time the offence was committed.

Two limbs, two different tests

The first limb covers offences committed in prosecution of the common object: offences directly connected with what the assembly set out to do. The second limb goes further, covering offences the members knew were likely to be committed in prosecuting that object, even if not part of the original object. Courts insist on keeping the two limbs apart. If an assembly gathered only to beat someone, a sudden killing by one member may fall outside both limbs, unless the others knew death was likely.

How the common object is proved

The common object is rarely stated. Courts infer it from the nature of the assembly, the weapons carried, and the members' conduct before, during and after the incident. It may also change during the incident.

Mere presence is not enough

A bystander or curious spectator is not a member of an unlawful assembly. The prosecution must show the accused shared the common object, for example by words, conduct or carrying weapons. In crowd cases, courts are cautious about convicting people named only as being present.

Contrast with section 34

Section 34 needs a prior meeting of minds and participation in the act. Section 149 needs neither; membership of the assembly with the common object is enough. Section 149 needs at least five persons; section 34 needs only two.

Key Supreme Court rulings

  • Zainul v. The State of Bihar 2025 INSC 1192

    Stressed that the distinction between the two parts of section 149 cannot be ignored, and that "in prosecution of the common object" means the offence must be directly connected with the common object. The common object is inferred from the nature of the assembly, the weapons carried and the members' conduct.

  • Dhirubhai Bhailalbhai Chauhan v. State of Gujarat 2025 INSC 381

    Mere presence at the scene does not make a person part of an unlawful assembly; without evidence of an inculpatory role, arrest on the spot did not rule out presence as a bystander or spectator.

  • Vasant @ Girish Akbarasab Sanavale v. State of Karnataka 2025 INSC 221

    Under section 149, participation in action, the leading feature of section 34, is replaced by membership of the assembly at the time of the offence.

Common mistakes

  • Applying section 149 when fewer than five persons are proved to be members. If some accused are acquitted and fewer than five remain (with no others unidentified), there is no unlawful assembly.
  • Ignoring the second limb's test. The question is what the members knew was likely, not what one member did on impulse.
  • Convicting spectators. Membership must be proved, not presumed from presence.
