Official Text
“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. Explanation—If the assembly is an unlawful assembly within the meaning of section 141, the offender will be punishable under section 145.”
Legal Analysis
Elements to Prove:
- An assembly of five or more persons existed.
- The assembly was likely to cause a disturbance of public peace.
- A lawful command was given for it to disperse.
- The accused knew of the command and still joined or continued in the assembly.
Potential Defenses:
- An accused can argue they were not aware of the dispersal order.
- They could also argue that the assembly was peaceful and not likely to cause any disturbance, making the dispersal command unnecessary or unlawful.
Practical Examples
What Constitutes the Offense:
Following a tense cricket match in Hyderabad, a large, agitated crowd of 100 people gathers at a major intersection, blocking traffic and shouting slogans. Their assembly doesn't have a specific unlawful object under §141, but it is "likely to cause a disturbance." Police lawfully command them to disperse. A person who hears this command but knowingly remains in the crowd is guilty under this section.
What Doesn't Constitute:
If the same crowd had gathered with the specific common object to attack the opposing team's supporters, it would be an unlawful assembly from the start. In that case, defying a dispersal order would be the more serious offense under Section 145.
Important Case Laws
Marasu and Ors. v. State
The court clarified that Section 151 applies to an assembly that may not have an unlawful common object but becomes a threat to public peace simply by its presence or behaviour. The purpose of this section is preventive—to disperse crowds before they become violent or overtly unlawful.
Punishment
Imprisonment for up to 6 months, or a Fine, or both

Connected Sections:
This section is a critical tool for maintaining public order. It must be read in contrast with §145. §145: Applies to an assembly that is already unlawful (has one of the five objects in §141). Punishment is up to 2 years. §151: Applies to any assembly (even initially lawful) that merely threatens public peace. Punishment is less severe (up to 6 months).
Procedural Aspects:
No government sanction is required for prosecution. The offense is triable by any Magistrate.
