STATE OF U.P. vs MAHENDRA SINGH & ORS.

The Supreme Court held that under Section 149 IPC, every member of an unlawful assembly is liable for the offences committed by any member in prosecution of its common object. The Court found that the assembly was unlawful as per Section 141 IPC, and the members knew that their actions could likely result in murder. The Court overturned the High Court's acquittal of several accused, emphasizing that all members of the assembly were united in purpose and thus liable for the murders that occurred, leading to the conviction of the accused under Sections 302 and 201 IPC.
