Section 149 IPC Cannot Be Invoked If Number Of Convicted Persons Falls Below Five After Acquittal Of Co-Accused: Allahabad High Court

"An assembly of less than five members is not an unlawful assembly within the meaning of Section 141 and cannot, therefore, form the basis for conviction for an offence with the aid of Section 149 IPC", Allahabad High Court, in a significant ruling dated April 24, 2026, held that a conviction with the aid of Section 149 of the Indian Penal Code (IPC) cannot be sustained if the acquittal of co-accused persons reduces the number of offenders to less than five.

Justice Samit Gopal observed that the existence of an "unlawful assembly" as defined under Section 141 IPC is a non-negotiable prerequisite for invoking vicarious liability under Section 149 IPC. The Court set aside the conviction of an appellant who had been found guilty alongside only one other person after four co-accused were acquitted.

The case originated from a 1986 land boundary dispute in Basti district, where the informant and his son were allegedly assaulted by seven named individuals armed with lathis. While the trial began against six persons following the death of one accused, the Trial Court acquitted four of them and convicted only the two appellants under Section 323/149 IPC. During the pendency of the appeal, the first appellant died, leaving the surviving appellant, Bigranchhu, to contest the legality of being convicted for an unlawful assembly that effectively consisted of only two people.

The primary question before the court was whether a conviction with the aid of Section 149 IPC can be maintained when the number of identified and convicted persons falls below the statutory minimum of five. The court was also called upon to determine if the acquittal of four co-accused persons, which had attained finality, fundamentally altered the legal character of the assembly for the remaining two accused.

Court Examines Definition of Unlawful Assembly Under Section 141 IPC

The bench observed that the very birth of an "unlawful assembly" depends on the numerical strength of the participants. Referring to the statutory language, the Court noted that an assembly of less than five members does not meet the legal definition.

"It is an essential condition of an unlawful assembly that its membership must be five or more," the Court stated, highlighting that this is a "necessary postulate" for invoking Section 149.

Effect Of Acquittal On Vicarious Liability Under Section 149 IPC

The Court placed heavy reliance on the five-judge bench decision of the Supreme Court in Mohan Singh v. State of Punjab. It noted that if five or more persons are named in a charge and some are acquitted, the assembly must be deemed to have been composed of only the remaining persons unless there is evidence of unidentified participants.

"As soon as two of the five named persons are acquitted, the assembly must be deemed to have been composed of only three persons and that clearly cannot be regarded as an unlawful assembly."

No Evidence Of Unnamed Or Unidentified Participants

Justice Gopal pointed out a crucial distinction in criminal jurisprudence: while it is not always necessary to convict five people to satisfy Section 149, the prosecution must prove that five or more people were involved. This can include unnamed or absconding persons.

However, in the present case, the Court found that the prosecution had specifically named only seven individuals. Since four were acquitted and one had died, only two remained. There was no case made out by the prosecution that any other unidentified persons were involved in the assault.

"When the other co-accused persons faced trial and have been given benefit of doubt and have been acquitted, it would not be permissible to take the view that there must have been some other persons along with the appellant."

High Court Applies Precedents On Constructive Liability

The Court cited Subran v. State of Kerala to reiterate that the failure of the prosecution to prove the assembly was "unlawful" by virtue of its size must result in the failure of the charge under Section 149 IPC. The bench noted that the acquittal of the four co-accused had attained finality and was not under challenge.

In such circumstances, the two remaining accused could not be held liable for the actions of an "unlawful assembly" that the law no longer recognized as having existed.

"The acquittal of four accused rendered Section 149 I.P.C. inapplicable in this case as only two accused were convicted."

Concluding the reasoning, the Court held that the Trial Court's judgment was "totally illegal" for convicting only two persons with the aid of Section 149 IPC. The Court emphasized that once the number of participants is found to be less than five, and there is no evidence of others, the legal foundation for an unlawful assembly collapses.

The High Court allowed the appeal and acquitted the surviving appellant, Bigranchhu. It ruled that the conviction under Section 323/149 IPC could not stand because the mandatory requirement of five members for an unlawful assembly was not met following the acquittal of the co-accused. The ruling reinforces the principle that vicarious liability under Section 149 IPC is strictly conditional upon the numerical and intentional requirements of Section 141 IPC.
