Section 146

The provision comes from British-era codification of group-violence offences in the IPC (1860). Colonial and later Indian lawmakers wanted a mechanism to hold entire mobs accountable for collective violence, since identifying the exact individual who threw the first stone or struck the first blow is often impossible in a crowd. By tying liability to membership in an unlawful assembly rather than individual acts, the law aimed to deter people from joining or remaining in groups formed for illegal purposes that turn violent.

Indian courts have consistently read Section 146 together with Sections 141 (definition of unlawful assembly) and 149 (punishment for offences committed by members in prosecution of common object). Courts have held that mere presence in a crowd is not enough; the prosecution must show the accused shared the common object and that the assembly (or a member) actually used force or violence toward that object. Judgments have also clarified that 'common object' can be inferred from conduct, weapons carried, and the nature of the assembly, even without prior explicit agreement — distinguishing it from the requirement of 'common intention' under Section 34.

• Myth: Only the person who actually used violence can be charged with rioting.
  Fact: Courts have held that every member of an unlawful assembly who shares its common object can be guilty of rioting if force is used by the assembly or even by one member, under Section 146 read with Section 149.
• Myth: Simply being present in a crowd where violence occurs makes you a rioter.
  Fact: Courts require proof that the person was a member of the unlawful assembly and shared its common illegal object — mere passive presence without shared purpose is not enough (simplified).
