THE STATUTE
Original Text
Whoever is a member of an unlawful assembly, shall be punished with imprisonment of either description for a term which may extend to six months, or with fine, or with both.
Simplified
Section 143 punishes mere membership in an unlawful assembly — every member of the assembly is guilty once the common object is proved, regardless of whether they personally committed a violent act. The 6-month maximum is relatively modest, reflecting that membership without violence is at the lowest end of collective criminal liability. The punishment escalates significantly if force is used (rioting — Section 147, 2 years), deadly weapons are present (Section 148, 3 years), or death results (collective murder liability under Section 149 r/w 302).
Legal Evolution
Section 143 was modeled on the English Unlawful Assemblies Act and the Riot Act 1714, which allowed authorities to disperse gatherings threatening public order. Macaulay's draft codified the offence to give magistrates and police a clear statutory basis for action against unlawful assemblies in colonial India. The provision has been consistently used in post-Independence India to manage mob violence and political gatherings that turn disorderly.

RELEVANCE
In large mob situations, membership in the unlawful assembly at the time of violence satisfies Section 143 — individual act attribution is not required.
Practical Scenarios
"Being part of a group that refuses to disperse after a lawful order by a magistrate."
"Remaining in an unlawful assembly knowing its criminal object but not personally committing any act."
