IPC Section 149 - Every Member of Unlawful Assembly Guilty of Offence Committed in Prosecution of Common Object
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.
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.”
Legal Analysis
Elements to Prove:
- A criminal offense was committed by a member of an unlawful assembly.
- The offense was committed "in prosecution of the common object" OR was an act the members "knew to be likely" to be committed.
Potential Defenses:
- A member can argue that the crime committed was the independent act of the perpetrator and had no connection to the group's common object.
- They can also argue that the crime was so unforeseen that no member could have known it was a likely consequence of their common object.
Practical Examples
What Constitutes the Offense:
A group of five people assembles with the "common object" of beating a rival with sticks. During the assault, one member unexpectedly pulls out a knife and stabs the rival, killing him. All five members can be convicted of murder under §302 read with §149. The court may conclude that when the common object is to assault someone with weapons like sticks, every member knew that causing a fatal injury was a likely outcome.
What Doesn't Constitute:
A group forms an unlawful assembly to peacefully but forcibly block a road (their common object is mischief under §425). One member sees their personal enemy in a nearby car, runs over, and assaults them. The other members would likely not be guilty of the assault under §149, as this was a personal act of that one member and was not done in prosecution of the common object (blocking the road).
Important Case Laws
Masalti v. State of U.P. (1964)
A landmark judgment where the Supreme Court held that once a person's membership in an unlawful assembly is established, they are vicariously liable for the crime committed by any other member in furtherance of the common object. It is not necessary to prove that they took an active part in the final criminal act.
Waman v. State of Maharashtra (2011)
The court explained the two distinct parts of this section: 1) The crime was committed to achieve the common object. 2) The crime was one that all members knew was likely to happen, even if it wasn't the primary goal.
Punishment
This section is a rule of vicarious liability and does not create a separate offense or punishment. It makes every member of an unlawful assembly responsible for a crime committed by another member. The punishment is the same as for the main crime committed (e.g., murder, grievous hurt).

Connected Sections:
This section is one of the most powerful tools in the IPC for prosecuting group violence. It is often contrasted with §34 (common intention), which requires a pre-arranged plan and active participation, whereas §149 requires only membership in the unlawful assembly at the time of the crime. It is always "read with" (r/w) a substantive offense like §302 (Murder), §307 (Attempt to Murder), or §326 (Grievous hurt by dangerous weapons).
Procedural Aspects:
This section creates vicarious liability and does not create a separate offense. The punishment depends on the main offense committed by any member of the assembly.
