Common Intention (Section 34 IPC / BNS 3(5)) and Unlawful Assembly (Section 149 IPC / BNS 190): How Group Liability Works

The Bharatiya Nyaya Sanhita (BNS) came into force on 1 July 2024 and replaced the Indian Penal Code (IPC). The group-liability provisions were carried over with almost identical language, so decades of Supreme Court interpretation continue to apply. The table below maps the old sections to the new ones.

A few points to keep in mind about this mapping:

• Numbers changed, substance did not. BNS Section 3(5) reads in substance like the old Section 34, so a First Information Report may still colloquially refer to "34" even under the new code.
• Conspiracy is different. Section 120B IPC (now BNS Section 61(2)) punishes the agreement itself and is a distinct charge, not merely a liability rule.
• FIRs often cite more than one. Police frequently add both 3(5) and 190 as a safety net, which is exactly why an early challenge to over-charging matters. See our note on FIR quashing when sections are wrongly slapped on.

The single most important distinction in group-crime law is this: common intention (Section 34 / BNS 3(5)) requires a prior meeting of minds, while common object (Section 149 / BNS 190) requires only membership of an unlawful assembly of five or more persons. One turns on a shared plan; the other turns on numbers plus a shared object. The comparison table sets out the practical differences.

Why this matters in practice:

• If the group is fewer than five people, Section 149 / BNS 190 cannot apply at all, and the prosecution must fall back on common intention, which is harder to prove.
• Common intention almost always has to be inferred from the circumstances, because no one records a plan. That inference is the battleground at trial.
• Common object is wider and can catch a bystander who joined a mob, which is why membership and presence are so heavily contested.

Courts do not convict on group liability mechanically. They insist that the prosecution prove the ingredients, and appellate courts routinely acquit where the evidence is thin. A leading authority on common object is Lalji v. State of Uttar Pradesh (1989), where the Supreme Court explained that Section 149 IPC creates a form of vicarious or constructive liability: once it is shown that a person was a member of an unlawful assembly and shared its common object, he becomes liable for an offence committed by any member in prosecution of that object, even if he did no overt act himself.

The Court was equally clear about the limits of the doctrine. Key takeaways from how the principle is applied:

• Membership must be proved, not assumed. Mere presence at the scene, without proof that the person shared the common object, is not enough to fix liability.
• The object must be a common object of the assembly, and the offence must be committed in prosecution of that object or be something the members knew was likely to be committed.
• Overt act is not always required under common object, which is precisely why courts scrutinise membership and knowledge so carefully.

For common intention under Section 34, courts have long held that the shared intention must be proved as a fact, usually inferred from the accused's conduct, the weapons carried, and the sequence of events. A sudden individual act outside the shared plan generally falls outside common intention. These are appeals frequently argued before the Allahabad High Court, Lucknow Bench, and outcomes often turn on medical evidence, injuries, and the number and role of each accused. Serious group cases commonly involve charges such as murder under Section 302 IPC (BNS 103) or attempt to murder under Section 307 IPC (BNS 109) read with 3(5) or 190.

Being named in a group FIR under BNS 3(5) or 190 does not mean the case against you is strong. In group cases, the prosecution often lists many accused and then struggles to attribute a specific role to each. Here are the steps to take, in order:

1. Read the FIR and see which liability rule is invoked. Check whether it is 3(5), 190, or both, and count how many accused are named, because fewer than five defeats common object.
2. Pin down your specific role. Note whether the complaint attributes any overt act to you or simply groups you with the others; vague, omnibus allegations are a recognised weakness.
3. Secure bail early. In group cases where no specific act is attributed to you, this is a strong bail point. See our bail and anticipatory bail guidance and, if no arrest has happened yet, act before it does.
4. Preserve alibi and location evidence. Call records, CCTV, and witnesses that place you away from the scene attack the membership and presence element directly.
5. Challenge over-charging. Where sections are added without material, a challenge or an application to drop the group-liability charge may be available; our FIR quashing page explains the route.
6. Get advice specific to your facts. The difference between common intention and common object can decide whether you are convicted at all, so speak to a lawyer through the contact page before making any statement.

Advocate Onkar Pandey (Bar Council of UP enrolment number UP 4825-1999) practises before the Allahabad High Court, Lucknow Bench, with a focus on criminal defence, group-crime and constructive-liability cases, bail, and trial strategy across Lucknow and the wider Awadh region. He regularly defends accused persons named in group FIRs under Section 34 and Section 149 IPC and their BNS successors, where the fight is usually over role, presence, and the number of persons involved.
