IPC Section 142: Being a Member of an Unlawful Assembly

Section 142 of the Indian Penal Code, 1860 defined when a person becomes a member of an unlawful assembly. The corresponding current rule is contained in Section 189(2) of the Bharatiya Nyaya Sanhita, 2023 (BNS).

Section 142 IPC: Definition of membership of an unlawful assembly

The original text of Section 142 of the Indian Penal Code, 1860 stated:

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.

In simple terms, membership depends on a person's awareness of the circumstances making the gathering unlawful and the person's intentional decision to join or remain in that gathering. Section 142 was a definition provision; punishment for ordinary membership was prescribed separately by IPC Section 143.

Essential ingredients of Section 142 IPC

1. An unlawful assembly exists: Under former IPC Section 141, there must ordinarily be an assembly of five or more persons sharing one of the prohibited common objects specified in that section.
2. Awareness of relevant facts: The person must know the facts that make the assembly unlawful; merely being near a gathering is not automatically enough.
3. Intentional participation: The person must intentionally join or continue in the assembly with the requisite awareness.
4. Continuing membership: An initially lawful gathering can subsequently become unlawful. A person who knowingly remains after the relevant change may fall within the provision.

The common object need not always be established by an express agreement. It may be inferred from the conduct of participants and the surrounding circumstances, but the statutory requirements must be proved on the evidence.

Current law: Section 189 of the Bharatiya Nyaya Sanhita, 2023

Section 189(1) BNS defines an unlawful assembly as a gathering of five or more persons having a specified unlawful common object. These objects include using or threatening criminal force to overawe public authorities, resisting execution of law or legal process, committing an offence, using criminal force to interfere with property or rights, or compelling someone through criminal force to act or refrain from acting against their legal entitlement.

Section 189(2) BNS combines the substance of former IPC Sections 142 and 143: a person who, knowing the facts that make an assembly unlawful, intentionally joins or continues in it is a member and may be punished with imprisonment of either description for up to six months, a fine, or both.

Section 189 also addresses aggravated or related circumstances, including continuing after a lawful dispersal command, being armed with a deadly weapon, and hiring persons to participate in an unlawful assembly.

Punishment and procedural classification

Under the First Schedule to the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), the offence of being a member of an unlawful assembly under BNS Section 189(2) is cognizable and bailable, and is triable by any Magistrate. Other offences alleged in the same case may carry different consequences.

Practical examples and important distinctions

Example 1: Knowing participation

Five or more people gather with a common object to forcibly prevent the execution of lawful process. A person who understands that purpose and deliberately joins them may be treated as a member of an unlawful assembly.

Example 2: Initially lawful gathering

A peaceful gathering later develops a prohibited common object. A participant who becomes aware of that change and intentionally remains may incur liability; the initial lawfulness of the gathering is not conclusive.

Example 3: Mere presence

A passerby or bystander who happens to be present without the requisite awareness and intentional membership is not made a member merely by physical proximity. The evidence and individual circumstances remain decisive.

Distinction between membership and liability for other offences

Former IPC Section 149 and current BNS Section 190 concern liability of members for offences committed in prosecution of the assembly's common object, or such as members knew were likely to be committed. This is distinct from the basic membership offence. Rioting is separately addressed under BNS Section 191 (formerly IPC Sections 146 to 148).

Frequently asked questions

Is IPC Section 142 still in force?

No. The IPC was repealed with effect from 1 July 2024, subject to savings. IPC Section 142 remains important for understanding and dealing with conduct governed by the earlier law.

Which BNS section corresponds to IPC Section 142?

BNS Section 189(2) contains the corresponding membership definition and also provides the punishment previously stated in IPC Section 143.

Can a person be liable without personally committing violence?

Yes. Where the statutory elements of unlawful assembly membership are proved, the membership offence does not require proof that the individual personally used violence. Liability for another member's separate offence requires the additional legal conditions applicable to that offence.
