IPC Section 151: Joining an Assembly After a Dispersal Order - BNS 189(5)

Section 151 of the Indian Penal Code, 1860 dealt with knowingly joining or remaining in an assembly of five or more persons likely to disturb public peace after a lawful direction to disperse. The corresponding provision under the Bharatiya Nyaya Sanhita, 2023 is Section 189(5).

Current provision: BNS Section 189(5), applicable under the new criminal law from 1 July 2024.

Maximum punishment: Six months' imprisonment of either description, or fine, or both.

Important exception: If the assembly is an unlawful assembly under BNS Section 189(1), Section 189(3) applies, with a maximum of two years' imprisonment, or fine, or both.

What did IPC Section 151 provide?

Section 151 IPC - 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.

Explanation: If the assembly is an unlawful assembly within the meaning of section 141, the offender will be punishable under section 145.

This reproduces the substantive text of the former provision, with punctuation standardised. For conduct before 1 July 2024, the IPC and the applicable repeal-and-savings provisions must be considered.

BNS Section 189(5): Current provision and punishment

Section 189(5) of the Bharatiya Nyaya Sanhita, 2023 substantially carries forward IPC Section 151. It applies when a person knowingly joins or continues in an assembly of five or more persons likely to cause a disturbance of public peace after that assembly has been lawfully commanded to disperse.

The prescribed punishment is imprisonment of either description for a term up to six months, or a fine, or both. The explanation to Section 189(5) expressly states that, where the gathering is an unlawful assembly under Section 189(1), the offender is punishable under Section 189(3).

Section 189(3) addresses knowingly joining or continuing in an unlawful assembly after it has been commanded in the manner prescribed by law to disperse; its maximum imprisonment is two years, or fine, or both.

Essential ingredients of the offence

  1. Assembly of five or more persons: The gathering must satisfy the statutory minimum.
  2. Risk to public peace: The assembly must be likely to cause a disturbance of public peace.
  3. Lawful dispersal command: A direction to disperse must have been given lawfully.
  4. Knowledge and continued participation: The accused must knowingly join or remain after the dispersal command.
  5. Evidence of the circumstances: The order, its communication, the conduct of participants and the circumstances must be assessed on the evidence.

Mere presence at a peaceful gathering does not by itself prove every element of this offence. The statutory requirements, including a lawful order and knowing participation after it, remain essential.

IssueProvisionMaximum imprisonment

What is an unlawful assembly?

Under BNS Section 189(1), an assembly of five or more persons is an unlawful assembly when its common object falls within the specified prohibited purposes. These include using or showing criminal force to overawe government or public servants, resisting the execution of law, committing offences, forcibly asserting property rights, or compelling a person by criminal force to act or refrain from acting. An initially lawful assembly may subsequently become unlawful.

Thus, the five-person dispersal offence under Section 189(5) and the offence relating to an unlawful assembly under Section 189(3) should not be treated as interchangeable.

Practical illustrations

Illustration 1: Continued gathering after lawful dispersal order

Six persons gather in circumstances likely to disturb public peace. An authorised officer lawfully directs the gathering to disperse. A participant hears the direction but knowingly remains. Subject to proof of all statutory elements, BNS Section 189(5) may apply.

Illustration 2: Unlawful assembly after dispersal order

Five persons assemble with a common object of resisting execution of law by criminal force. They knowingly remain after a lawful command to disperse. If the assembly meets BNS Section 189(1), Section 189(3), rather than the lesser punishment under Section 189(5), becomes relevant.

Illustration 3: Peaceful gathering

Five people gather peacefully without a likelihood of disturbing public peace and without a lawful dispersal command. Their mere presence together does not establish the ingredients of BNS Section 189(5).
