Sections 141, 142 and 143 IPC - Unlawful Assembly, Membership and Punishment

Sections 141 to 143 of the Indian Penal Code, 1860 worked together to define an unlawful assembly, identify when a person becomes its member, and prescribe punishment for membership. These provisions formed part of Chapter VIII of the IPC, dealing with offences against public tranquillity.

Legal position covered: This article explains Sections 141, 142 and 143 IPC and the Code of Criminal Procedure, 1973 classification applicable immediately before the Bharatiya Nyaya Sanhita, 2023 came into force.

Section 141 IPC - Unlawful assembly

An assembly of five or more persons is designated an "unlawful assembly" if the common object of the persons composing that assembly is one of the five objects specified in Section 141 IPC.

First: To overawe by criminal force, or show of criminal force, the Central or any State Government or Parliament or the Legislature of any State, or any public servant in the exercise of the lawful power of such public servant.

Second: To resist the execution of any law, or of any legal process.

Third: To commit any mischief or criminal trespass, or other offence.

Fourth: By means of criminal force, or show of criminal force, to any person, to take or obtain possession of any property, or to deprive any person of the enjoyment of a right of way, or of the use of water or other incorporeal right of which he is in possession or enjoyment, or to enforce any right or supposed right.

Fifth: By means of criminal force, or show of criminal force, to compel any person to do what he is not legally bound to do, or to omit to do what he is legally entitled to do.

Explanation: An assembly which was not unlawful when it assembled may subsequently become an unlawful assembly.

Essential requirements of an unlawful assembly

There must be an assembly of at least five persons.
The persons composing it must have a common object.
That common object must fall within at least one of the five categories specified in Section 141.
An assembly lawful at its beginning may later become unlawful if its common object changes so as to fall within Section 141.

Meaning of "common object"

Section 141 is framed around the common object of the assembly. The relevant object must be shared by the persons composing the unlawful assembly and must be one of the statutory objects set out in the section. The concept is important not only for Section 141 but also for other Chapter VIII provisions dealing with membership, rioting and liability for offences committed in prosecution of the common object.

Section 142 IPC - Being a member of unlawful assembly

142. Being member of unlawful assembly. Whoever, being aware of facts which render any assembly an unlawful assembly, intentionally joins that assembly, or continues in it, is said to be a member of an unlawful assembly.

What Section 142 requires

Section 142 adds a knowledge and intention requirement to membership. The person must be aware of the facts that make the assembly unlawful and must intentionally join it or intentionally continue in it. Mere physical presence, without the statutory awareness and intentional joining or continuation, does not by itself reproduce the full definition in Section 142.

Section 143 IPC - Punishment for unlawful assembly

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.

Related provisions on unlawful assembly and rioting

The IPC contained progressively related provisions following Section 143. Sections 144 and 145 IPC dealt with joining an unlawful assembly armed with a deadly weapon and joining or continuing in an unlawful assembly after it had been commanded to disperse. Sections 146 to 148 IPC dealt with rioting and rioting while armed with a deadly weapon.

Historical amendment note

The wording in the first clause of Section 141 referring to the "Central or any State Government or Parliament or the Legislature of any State" reflects the post-Constitution adaptation of the earlier statutory language.
