Definition
The shared unlawful purpose of an unlawful assembly — every member of an unlawful assembly is vicariously liable for any offence committed by any member in prosecution of the common object, or which they knew was likely to be committed.
Section 11(2) of the Bharatiya Nyaya Sanhita (BNS), 2023 (formerly Section 149 IPC) creates group criminal liability for unlawful assemblies. An 'unlawful assembly' is defined in Section 11(1) BNS (formerly Section 141 IPC) as an assembly of five or more persons with one of five specified common objects: (a) overawing the State or its officers by criminal force; (b) resisting execution of legal process; (c) committing any mischief, criminal trespass, or other offence; (d) taking or obtaining possession of property by criminal force or show of force; or (e) compelling any person by criminal force to do what they are not legally bound to do. Common object requires no pre-planning — it may form spontaneously as the assembly begins acting.
Statutory Definition
Section 11(2), Bharatiya Nyaya Sanhita (BNS), 2023 (formerly Section 149 IPC): '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.' Section 11(1) BNS defines 'unlawful assembly' as an assembly of five or more persons with one of the five specified common objects.
Etymology & Origin
The word 'object' here means 'objective' or 'purpose' (from Latin 'objectum' — something thrown before one, an aim). The 'common object' is the shared purpose/aim that all members of the unlawful assembly pursue together.
Full Legal Analysis
Common Object: The Law of the Mob
Common object is the cornerstone of Indian mob violence jurisprudence. When a group of five or more persons assemble for an unlawful purpose and violence occurs, the law does not require the prosecution to identify which hand struck the fatal blow. Every member who was part of the assembly, knowing or reasonably knowing of its unlawful common object, is equally guilty. This principle has been applied in hundreds of riot, communal violence, and dacoity cases in Indian criminal law.
Two Limbs of Section 11(2) BNS
(a) First limb — 'in prosecution of the common object': The offence must have been committed in furtherance of the common object that the assembly was pursuing. All members who were part of the assembly at the time are liable — even if they did not know the specific offence was going to be committed, as long as it was in pursuit of the shared purpose. (b) Second limb — 'knew to be likely': Even if the specific offence committed was not the assembly's explicit common object, every member who knew at the time that the offence was likely to be committed in prosecution of the common object is also guilty. This second limb creates very broad liability — a member of an assembly that sets out to commit criminal trespass is also liable for murder if they knew violence was likely.
Common Object vs. Common Intention: Comparison
(a) Common intention (Section 3(5) BNS): Requires a specific shared criminal intent — 'meeting of minds' on a particular offence; two persons minimum; may be formed spontaneously; liability only for acts in furtherance of the specific shared intent. (b) Common object (Section 11(2) BNS): Requires an unlawful assembly of five or more; liability extends to any offence committed in prosecution of the object OR likely to be committed; does not require shared intent in the same specific manner — presence in the assembly is sufficient if the common object is established.
“Section 11(2) BNS is the law's response to mob violence — it refuses to let members of a violent assembly shield themselves by saying 'I didn't throw the stone.' You joined the mob, you knew its purpose, and you stayed. The law holds you responsible for what your fellow mob members did.”
