Difference Between Common Intention and Criminal Conspiracy Under BNS

Difference Between Common Intention and Criminal Conspiracy Under BNS

Common intention vs Criminal conspiracy

Common intention and criminal conspiracy are two ideas students routinely mix up — and it’s easy to see why. Both describe a situation where more than one person shares an understanding to commit a crime. But the law does not treat the two as interchangeable, and knowing exactly where they part ways is one of the more frequently tested distinctions in criminal law.

Common intention is governed by Section 3(5) of the Bharatiya Nyaya Sanhita, 2023 (BNS). Criminal conspiracy is governed by Section 61 of the BNS. At a conceptual level, the two are not far apart — both involve a shared understanding between people before or during a criminal act. Where they genuinely diverge is in when the law considers an offence to have occurred.

What Is Common Intention? (Section 3(5) BNS)

Under Section 3(5), when several persons carry out a criminal act together, in furtherance of an intention all of them share, each participant is treated as though he committed the entire act on his own — not just his individual part in it.

Key Point: Section 3(5) is declaratory in nature — it does not, on its own, define or create any offence. It only becomes relevant once a criminal act has actually taken place, and its role is to fix how liability for that act is distributed among the participants, not to punish the shared intention by itself.

What Is Criminal Conspiracy? (Section 61 BNS)

Section 61 covers a situation where two or more persons reach an understanding to:

• carry out an act that is itself illegal, or
• carry out an act that is not illegal on its own, but through means that are illegal

Key Point: Unlike Section 3(5), Section 61 is itself a substantive offence. The act of forming such an agreement is, by itself, sufficient to attract criminal liability — the parties don’t need to have taken any further step toward actually committing the planned crime.

The Core Difference

Basis	Common Intention (Sec 3(5) BNS)	Criminal Conspiracy (Sec 61 BNS)
Nature of the provision	Declaratory — it fixes liability, but does not itself define an offence	Substantive offence — the agreement itself amounts to a crime
When liability arises	Only once a criminal act has actually been carried out in pursuance of the shared intention	The moment two or more persons reach the agreement, regardless of what follows
What the prosecution must show	That an offence was in fact committed by two or more persons acting on a common plan	That an agreement existed to commit an illegal act, or a lawful act through illegal means
Is the agreement alone punishable?	No — without a completed criminal act, Section 3(5) does not fasten any liability	Yes — Section 61 punishes the agreement itself, even if the intended crime is never carried out

In Short: for liability to arise under Section 3(5), some criminal act must actually have been committed by two or more people acting together on a shared plan — the provision does nothing on its own before that. Under Section 61, however, liability attaches as soon as an agreement of the kind described in that section exists between two or more people; they can be convicted under it whether or not the planned offence is ever actually carried out.

Example to keep the distinction clear:

• Two people agree to commit a robbery, and are caught before doing anything else toward it → this falls under criminal conspiracy (Section 61) — the agreement by itself is enough for liability.
• Two people act together and assault someone, having formed a shared plan moments earlier → this falls under common intention (Section 3(5)) — liability follows only because the act was actually carried out.

Similar Intention (Like Intention) — Section 3(6) BNS: Joint Liability in Crimes Requiring Mens Rea

A related concept, often studied right alongside common intention.

Rule: Where a group of people take part in an act that is criminal only because of a particular state of mind — knowledge or intention — behind it, liability attaches separately to each participant based on their own individual knowledge or intention, rather than treating the group as sharing one collective mental state.

Application: This becomes relevant for offences where criminality turns on the mental element of the person committing the act — such as cheating, criminal breach of trust, or murder — situations where different people involved might hold different degrees of guilty knowledge even while participating in the same act.

How it differs from common intention: Section 3(5) treats the group as acting on one shared intention, making each person liable as though he alone had done the whole act. Section 3(6), by contrast, assesses each person’s liability on the basis of what he individually knew or intended, not a single intention attributed to the whole group.

Frequently Asked Questions

Conclusion

Common intention and criminal conspiracy both begin from the same starting point — people coming together with a shared understanding to commit a crime — but the law marks a clear boundary between them. Section 3(5) BNS only operates once the crime has actually been carried out; Section 61 BNS operates from the moment the agreement itself is formed. Add to this the way Section 3(6)’s “similar intention” differs from both, and the real testable point isn’t the definitions in isolation — it’s understanding precisely when each provision starts fixing liability.
