IPC Section 143: Punishment for Being a Member of an Unlawful Assembly
Section 143 of the Indian Penal Code, 1860 prescribed punishment for membership of an unlawful assembly. The corresponding provision under the Bharatiya Nyaya Sanhita, 2023 (BNS) is Section 189(2), which combines the definition of membership and its punishment.
Text of IPC Section 143: Punishment
"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."
In this provision, imprisonment of either description means rigorous imprisonment or simple imprisonment. The section prescribes a maximum term rather than mandatory imprisonment in every case.
Corresponding Law: BNS Section 189(2)
Section 189(2) of the Bharatiya Nyaya Sanhita, 2023 incorporates the substance of former IPC Sections 142 and 143. It states that a person who knows the facts making an assembly unlawful and intentionally joins or continues in it is a member of an unlawful assembly, punishable with imprisonment of either description for up to six months, fine, or both.

What Is an Unlawful Assembly?
Under former IPC Section 141 and current BNS Section 189(1), an assembly of five or more persons is unlawful when its members share any of the specified unlawful common objects. These include:
- Overawing the Government, a legislature, or a public servant by criminal force or its show.
- Resisting execution of a law or legal process.
- Committing mischief, criminal trespass, or another offence.
- Using or threatening criminal force to obtain property possession or interfere with specified rights.
- Using or threatening criminal force to compel a person to do something they are not legally bound to do, or to omit something they are legally entitled to do.
An initially lawful gathering can become unlawful if the requisite common object subsequently develops.
Essential Ingredients of the Offence
- Five or more persons: An assembly must satisfy the statutory numerical requirement.
- Unlawful common object: Its shared objective must fall within Section 141 IPC or Section 189(1) BNS.
- Knowledge: The accused must be aware of the facts that render the assembly unlawful.
- Intentional membership: The accused must intentionally join or continue in that assembly.
Mere presence at a public gathering, without proof of the necessary knowledge and intentional participation or continued membership, does not automatically establish this offence. Membership and the common object must be assessed from the evidence and surrounding circumstances.

Illustrative Examples
Example 1: Knowing participation
Six persons assemble with a shared object of forcibly taking possession of property. A seventh person knows this purpose and intentionally joins them. Depending on the evidence, that person may incur liability under BNS Section 189(2).
Example 2: Innocent presence
A passer-by stands near a gathering without knowing of its unlawful common object and does not intentionally join it. Proximity alone would not establish membership of the unlawful assembly.
Related Provisions and More Serious Offences
Membership is distinct from rioting and from liability for offences committed in prosecution of the assembly's common object. Depending on the facts, additional provisions may apply:
- BNS Section 189(3): Joining or continuing in an unlawful assembly knowing it has lawfully been ordered to disperse; punishment up to two years, fine, or both (former IPC Section 145).
- BNS Section 189(4): Membership while armed with a deadly weapon or an object likely to cause death when used as a weapon; punishment up to two years, fine, or both (former IPC Section 144).
- BNS Section 190: Liability of members for offences committed in prosecution of the common object, or known to be likely in prosecution of that object (former IPC Section 149).
- BNS Section 191: Rioting and its punishment, corresponding to former IPC Sections 146 to 148.
