Section 149

Section 149 was designed by the drafters of the IPC to address collective criminal violence, especially riots and mob-based crimes, which were common in colonial India. Individual criminal responsibility is hard to prove when a crime happens in a chaotic group setting. This section allows courts to hold every member of an unlawful assembly liable for offences committed in furtherance of, or reasonably foreseeable from, the group's common object, without needing to prove who struck the actual blow.

Indian courts, including the Supreme Court, have repeatedly clarified that 'common object' need not be a pre-arranged plan — it can form spontaneously and be inferred from the conduct, weapons carried, and behavior of the assembly at the time of the offence. Courts have held that mere presence in an assembly is not enough; there must be evidence of sharing the common object. Judgments have also stressed that the second limb — offences 'likely to be committed' — extends liability to unintended but foreseeable consequences of the group's actions, making this section broader than ordinary common intention under Section 34.

• Myth: Only the person who actually committed the crime can be punished under Section 149.
  Fact: Courts have clarified that every member of the unlawful assembly sharing the common object can be held guilty, even if they didn't personally commit the act.
• Myth: Just being present near an unlawful assembly makes you automatically guilty.
  Fact: Courts require proof that the person was a member of the assembly and shared its common object, not mere passive presence.
• Myth: The offence must be exactly what the group planned to do.
  Fact: Liability extends to offences the members knew were 'likely' to happen in pursuit of their common object, even if not specifically planned.
