Doctrine of Joint and Group Liability

Offences against Property

The Doctrine of Joint and Group Liability under the Bharatiya Nyaya Sanhita, 2023

I. Introduction: The Basis of Vicarious and Constructive Liability 

The fundamental tenet of criminal law, captured by the maxim actus non facit reum nisi mens sit rea (an act does not make a person guilty unless the mind is also guilty), primarily focuses on individual culpability. However, modern criminal jurisprudence must effectively address group criminality , where the collective strength, planning, and execution pose a far greater threat to public order than isolated acts.

The Bharatiya Nyaya Sanhita, 2023 (BNS) , replacing the Indian Penal Code, 1860 (IPC), preserves and rationalizes the principles of Joint and Group Liability through the doctrines of Common Intention and Common Object . These doctrines impose vicarious (indirect) and constructive (inferred) liability, ensuring that every participant in a criminal conspiracy or mob action is held responsible for the ultimate crime committed, even if their individual contribution was minimal. The BNS places these core interpretative rules in Chapter I (General Explanations) , specifically Sections 3(5) to 3(9) for Common Intention, and details the offense of Unlawful Assembly and its corresponding liability in Section 189 (Chapter XI: Of Offences Affecting the Public Tranquility).

The rationale for this collective liability is two-fold:

  1. Deterrence: To dissuade individuals from joining groups with criminal aims.
  2. Difficulty of Proof: To overcome the near-impossible task of proving the precise physical contribution and mens rea of every single person in a criminal group, especially in chaotic situations like a riot.
II. The Doctrine of Common Intention (BNS Sections 3(5) to 3(9)) 

The doctrine of Common Intention, codified in Section 3(5) of the BNS (formerly IPC S. 34), is a rule of evidence and a principle of joint liability , not a substantive offense in itself. It is invoked when two or more people act together, each making their own contribution, to achieve a crime that they all previously intended.

A. The Core Rule and Essential Ingredients (Section 3(5))

Section 3(5), BNS , states:

"When a criminal act is done by several persons in furtherance of the common intention of all, each of such persons is liable for that act in the same manner as if it were done by him alone."

  1. "Several Persons"

A minimum of two individuals is required. The liability is activated when multiple people are involved in the commission of the act.

  1. "Criminal Act"

The act committed must be an offense defined and punishable under the BNS.

  1. "In Furtherance of the Common Intention of All"

This is the mens rea cornerstone. It necessitates a pre-arranged plan or a prior meeting of minds ( consensus ad idem ).

  • Prior Concert: There must be evidence that the accused shared the same intention to commit the act before its execution.
  • Spur-of-the-Moment Intention: Judicial precedents consistently hold that common intention need not be long-term; it can develop on the spot or at the spur of the moment , immediately before or even during the commission of the act, but it must precede the criminal act itself.
  • Distinction from Same/Similar Intention: If A and B separately decide, without communicating, to assault Z simultaneously, their intentions are similar, not common. Common Intention requires the communication and acceptance of the plan by all members.
  1. "Participation"

While physical presence at the scene is the best proof of participation, it is not always mandatory. Active participation in the criminal act is sufficient. A person standing guard or serving as a getaway driver is considered to be participating in the act, as their presence is essential to the plan.

  • Example (S. 3(5)): A and B plan to shoot Z. A stands guard 50 meters away, while B fires the fatal shot. Both A and B are liable for murder because A's act of standing guard was an action done in furtherance of the common intention to kill Z.
B. Related Corollaries of Common Intention (Sections 3(6) to 3(9))

The BNS provides further rules for understanding joint criminal action:

BNS Section Principle Scope and Application Example
Section 3(6) Criminal Knowledge or Intention Where an act is criminal only by reason of the knowledge or intention behind it, all persons sharing that intent or knowledge are equally liable. A and B jointly give Z a large dose of a drug, knowing it may kill him. Both are liable if they shared the knowledge/intention.
Section 3(7) Co-operation in the Criminal Act When a crime is committed through several acts, anyone who intentionally cooperates by doing any one of those acts is fully guilty of the offense. A and B agree to kill Z by giving small poison doses over days. Both are guilty of murder due to cooperative acts.
Section 3(8) Different Offenses by Same Act Participants in the same act may be guilty of different offenses depending on their individual knowledge or intent. A, provoked by Z, hits him (culpable homicide). B helps A with intent to kill. A is guilty of the lesser offense; B is guilty of murder.
Section 3(9) Voluntarily Causing Effect A person causes an effect "voluntarily" when they act with the knowledge or belief that the outcome is likely. A knows a bridge is weak and drives a heavy truck on it, causing it to collapse and kill B. A is liable for B's death.

III. The Doctrine of Common Object and Unlawful Assembly (BNS Section 189) (

The doctrine of Common Object imposes liability on members of a specific type of criminal group: the Unlawful Assembly . This rule is a substantive offense against public tranquillity.

A. Definition of Unlawful Assembly (Section 189(1))

Section 189(1), BNS (formerly IPC S. 141) defines an 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—" (followed by five clauses detailing illegal objectives).

Essential Requirements for an Unlawful Assembly:

  1. Number: Must consist of five or more persons . If five persons are charged, but one or more are acquitted, reducing the proved number below five, the remaining members cannot be convicted under this section alone (unless BNS S. 3(5) is proven).
  2. Common Object: All members must share one of the five specific illegal objectives:
    • To overawe the Government or a public servant by criminal force.
    • To resist the execution of any law or legal process.
    • To commit any mischief, criminal trespass, or other offense.
    • To take or obtain property by criminal force or deprive a person of a right (e.g., right of way, water use).
    • To compel a person to do what they are not legally bound to do, or omit what they are legally entitled to do, by criminal force.
  3. Nature of Object: The object does not require a prior plan; it can form suddenly or evolve on the spot, but all members must knowingly share it.
B. Vicarious Liability under Common Object (Section 189(5))

The crucial section for Group Liability is Section 189(5), BNS (formerly IPC S. 149):

"If an offence is committed by any member of an unlawful assembly in prosecution of the common object of that assembly, or such as the members of that assembly knew to be likely to be committed in prosecution of that object, every person who, at the time of the committing of that offence, is a member of the same assembly , shall be guilty of that offence ."

This section imputes vicarious liability:

  1. Offence Committed: The actual crime must be committed by any member.
  2. Causal Link - First Limb: "In Prosecution of the Common Object": The offense must be committed directly to achieve the common object (e.g., if the object is to seize a field, the act of beating the guard to enter the field is in prosecution of that object).
  3. Causal Link - Second Limb: "Knew to be Likely": The offense committed, though not the direct common object, must be one which the members knew or ought to have known was a probable consequence of their actions (e.g., members of an assembly armed with sticks, whose object is only to seize property, must know grievous hurt is likely).
  • Example (S. 189(5)): A mob of six people (an Unlawful Assembly) assembles with the Common Object of burning down B's house. During the ensuing chaos, one member, C, suddenly pulls out a hidden knife and stabs an onlooker, Z, who was recording the scene. All six members are liable for the burning of the house (as it was the common object). They are also liable for the murder of Z if it can be proven that the members knew that violence and even fatal injury to any intervening party was likely in prosecution of their violent object.
C. Punishment for Membership (Section 189(2), (3))

The BNS separately punishes mere membership and related activities:

  • Section 189(2): Punishment for being a member of an unlawful assembly: Imprisonment up to six months , or fine, or both.
  • Section 189(3): Punishment for being a member of an unlawful assembly armed with a deadly weapon : Imprisonment up to two years , or fine, or both.
IV. Comparative Analysis: Common Intention vs. Common Object 

While both doctrines serve the function of collective criminal liability, their ingredients and scope are fundamentally distinct. Mistakenly substituting one for the other can lead to a miscarriage of justice, hence the judiciary maintains a strict separation.

Feature Common Intention
(BNS Section 3(5))
Common Object
(BNS Section 189(1) & (5))
Legal Status Rule of Evidence / Joint Liability
Does not create a separate offense but extends liability.
Substantive Offense
Part of Unlawful Assembly laws with constructive liability.
Minimum Persons Two or more persons required. Five or more persons mandatorily required.
Nature of Plan Requires a prior concert or pre-arranged plan ("meeting of minds"). No prior plan needed; object can arise on the spot.
Mental Element Intention: A specific and shared mens rea must exist for the resulting act. Object: A common illegal purpose; liability arises if the act was known to be likely.
Scope of Liability Narrower; act must be in furtherance of the common intention. Broader; includes acts done in prosecution of the object or those likely to be committed.
Participation Active participation required (physical presence or immediate aid). Mere membership in the assembly is sufficient, even if passive.
Failure of Proof If common intention is not proven, liability is only for the accused's individual act. If number drops below five, S. 189 charge fails, but S. 3(5) may still apply if a pre-arranged plan is proven.

Judicial Nuance: Overlap and Conversion

While distinct, the Supreme Court has ruled that a conviction based on Common Object (S. 189(5)) can be converted to Common Intention (S. 3(5)) if the following are proven:

  1. The number of accused convicted is at least two.
  2. The facts proved clearly establish a prior meeting of minds to commit the specific act (Common Intention).
  3. The accused were not prejudiced by the alteration of the charge.

This conversion highlights the overlapping, yet distinct, roles of the two doctrines in addressing collective crimes.

V. Conclusion

The transition to the Bharatiya Nyaya Sanhita, 2023 , has preserved the core jurisprudential weight of collective criminal liability. Common Intention (S. 3(5)) is a surgical tool, requiring a narrow, focused prior plan between a minimum of two people. Conversely, Common Object (S. 189) is a broad-spectrum instrument designed to combat the volatility and threat posed by large criminal mobs (five or more persons), casting a wide net of liability over all members who share the unlawful purpose or acquiesce to the likely consequences of their assembly. Together, these doctrines ensure that the Indian criminal justice system can effectively penetrate the shield of collective action to hold all individuals accountable, thereby upholding the primary objective of the BNS: delivering justice through clear, proactive, and comprehensive legal provisions.
