Supreme Court Reaffirms Vicarious Liability Under Section 149 IPC in 1983 Bihar Mass Violence Case
In a landmark verdict on the issue of unlawful assembly and collective criminal liability, the Supreme Court of India, in a 1983 Bihar mass violence case, quashed the appeals of some prisoners and confirmed that once the common object of an unlawful assembly is established, every member of such assembly is vicariously liable for offences committed for the purpose of that object, pursuant to Section 149 of the Indian Penal Code (IPC).
The incident came after a brutal case of violence in Muzaffarpur district of Bihar, on March 29, 1983. The violence was motivated by tensions and conflicts between and within villages over land used for farming.The violence was connected to the historical animosity between and within villages and land used for agricultural purposes. The prosecution alleged a large group of armed men attacked a dwelling house, burned it, and beat the residents. Five people were killed and many more – women and children – were seriously injured.
The Supreme Court, after considering the findings of both the Trial Court as well as the Patna High Court, confirmed their death sentence and life imprisonment. The injuries sustained by the eyewitnesses, independent witnesses and medical officers all proved that the accused was involved in the unlawful assembly and the violent attack.
The main point of law before the Court was the definition of Section 149 IPC. This rule establishes constructive or vicarious criminal responsibility in the case of an offence committed by a member of an unlawful assembly, in the prosecution of the common object of the assembly. Under such conditions, each member of the assembly may be held accountable even though a particular overt act may not be specifically attributed to any one particular member.
The appellants contended that majority of them were at the scene but did not take active part in the killing. They also argued that the incident was not planned and was a sudden dispute, which meant there was no common object. The Supreme Court however made it clear that the nature of attack, the size of the armed mob and the coordinated attack by the assailants clearly indicated a common object.
The Court pointed out that the common objective of the illegal assembly has been established, and there was no need to prove each and every act against every accused. Section 149 IPC imposes liability on members of the assembly, whether through membership or participation in the activities of the assembly. The Bench pointed out that a mere passive presence in an assembly cannot be the basis for the absence of a criminal responsibility if the evidence indicates that the person was involved with the illegal assembly.
An important feature of the judgment was how the Court dealt with a public official who was caught up in the incident. The then Circle Officer was identified as being involved in the attack having disarmed the victims at an opportune time, thus encouraging the mob. The Court accepted his conviction for abetment, emphasizing the public servants’ duty of care for citizens and not to be complicit in violence.
The judgment also captures the general impression of the Supreme Court in its attitude towards mob violence. The courts have been aware that the provisions of section 149 IPC give rise to a broad vicarious liability and accordingly has to be used judiciously, but at the same time it has been understood that if everybody is required to have committed an overt act before they are held liable, organized mob violence would not be possible to tackle.
In the end, the decision affirms an important principle of Indian criminal law – that collective violence that is organized and directed for a common unlawful purpose is subject to collective responsibility. The Supreme Court uphold the convictions, thereby holding the principle more than 40 years after the incident, which established the principle that participation in an unlawful assembly with a common criminal purpose can be sufficient to render the members liable to criminal prosecution.
