Simply being part of a big crowd is illegal under this law.

The law only applies if the assembly is likely to disturb public peace AND a lawful order to disperse has been given and knowingly ignored.

This section punishes protestors just for protesting.

Courts have clarified that peaceful assembly and protest are protected; this section only targets continued presence after a valid dispersal order, not the act of gathering itself.

Indian Penal Code, 1860

Section 151

repealed

Knowingly joining or continuing in assembly of five or more persons after it has been commanded to disperse

Whoever knowingly joins or continues in any assembly of five or more persons likely to cause a disturbance of the public peace, after such assembly has been lawfully commanded to disperse, shall be punished with imprisonment of either description for a term which may extend to six months, or with fine, or with both.§

Why this exists

This provision comes from the colonial-era Indian Penal Code, drafted to give authorities a tool to prevent unlawful assemblies from escalating into riots or violence. It works alongside Section 144 of the Code of Criminal Procedure (which allows magistrates to order dispersal) by criminalizing defiance of a lawful dispersal order, aiming to maintain public order without necessarily charging people under harsher rioting laws.

How courts read it

Courts have generally held that for a conviction under this section, the prosecution must prove that the order to disperse was lawfully given (usually by a magistrate or police officer with authority) and that the accused knowingly continued to remain in the assembly despite that order. Mere presence without knowledge of the command to disperse, or an unlawful/improper dispersal order, has been held insufficient for conviction in various High Court rulings, though no single landmark Supreme Court judgment defines this section exhaustively.
