Criminal conspiracy under BNS S.61 is a substantive offence in its own right, distinct from the conspiracy mode of abetment under S.45(b). It criminalises the agreement itself, making it the earliest point at which the law intervenes in the chain from intention to commission.
BNS S.61 corresponds to IPC S.120A (definition) and S.120B (punishment). The BNS consolidates both into a single section with two sub-sections.
Definition: BNS S.61(1)
When two or more persons agree with the common object to do, or cause to be done:
- (a) an illegal act, or
- (b) an act which is not illegal by illegal means,
such an agreement is designated a criminal conspiracy.
Proviso: No agreement except an agreement to commit an offence shall amount to a criminal conspiracy unless some act besides the agreement is done by one or more parties in pursuance thereof.
Explanation: It is immaterial whether the illegal act is the ultimate object or is merely incidental.
What the Proviso Means
| Type of agreement | Overt act required? |
|---|---|
| Agreement to commit an offence (punishable under BNS or any penal law) | No. The agreement alone suffices |
| Agreement to do an illegal act that is not an offence (e.g. a civil wrong, a tort) | Yes. Some act in pursuance must be shown |
| Agreement to do a legal act by illegal means | Yes. Some act in pursuance must be shown |
Why the agreement alone suffices for serious offences: An agreement to commit an offence reveals a settled criminal purpose shared between at least two minds. The combination of persons pursuing a criminal object is itself dangerous, because it makes the commission more likely, more efficient and harder to detect. The law intervenes at the point of agreement to prevent that enhanced danger from materialising.
Punishment: BNS S.61(2)
| Category | Punishment |
|---|---|
| (a) Conspiracy to commit an offence punishable with death, life imprisonment, or rigorous imprisonment for 2 years or more | Same as if the conspirator had abetted the offence (i.e. same punishment as the principal offence, if committed; or fractions, if not) |
| (b) Any other criminal conspiracy | Imprisonment up to 6 months, or fine, or both |
Essential Ingredients
| Ingredient | Content |
|---|---|
| Two or more persons | A single person cannot conspire with himself. If all other alleged conspirators are acquitted, the remaining accused cannot be convicted of conspiracy (with exceptions for unknown co-conspirators) |
| Agreement | Meeting of minds; need not be express, may be inferred from conduct |
| Common object | The conspirators must share the object of the conspiracy |
| Illegal act or illegal means | The object must be either an illegal act or a lawful act achieved by illegal means |
How Agreement is Proved
Direct evidence of the agreement is rarely available (conspirators do not sign written contracts). The agreement is ordinarily inferred from:
- Conduct of the parties
- Acts done in pursuance
- Communications (letters, calls, messages)
- Meeting of the parties
- Similarity of action suggesting coordination
Facts: The assassination of Prime Minister Indira Gandhi. The question was whether Kehar Singh, who had not fired the shots, was part of the conspiracy.
Issue: How is membership of a conspiracy established?
Held: A conspiracy is proved by showing that the accused agreed to or acted in furtherance of the common criminal design. The agreement need not be proved by direct evidence; it may be inferred from circumstances and conduct. Each conspirator need not know the details of the plan or the identity of every other conspirator.
Relevance: The leading authority on proof of conspiracy and the scope of individual liability within a conspiracy.
Facts: The Rajiv Gandhi assassination case. Multiple accused at different levels of involvement.
Issue: The scope of liability of each conspirator for acts done by others in pursuance of the conspiracy.
Held: Once a conspiracy is established, every conspirator is liable for every act done by any conspirator in pursuance of the common object. A conspirator who joins at a later stage is liable for acts done before he joined, if they are in furtherance of the object. Withdrawal must be communicated and effective.
Relevance: The widest statement of conspirator liability. Cite for the proposition that joining a conspiracy makes a person liable for everything done in its pursuance.
Conspiracy Distinguished from Abetment by Conspiracy
| Basis | Criminal Conspiracy (S.61) | Abetment by Conspiracy (S.45(b)) |
|---|---|---|
| Nature | Substantive offence | Mode of abetment |
| Requires overt act? | Not for offences punishable with 2+ years | Yes, always (an act or illegal omission must take place in pursuance) |
| Parties | Two or more | Two or more |
| Liability if offence not committed | Punishable independently (S.61(2)) | Punishable as abetment of an uncommitted offence (S.55 or S.56) |
| Overlap | A person may be charged with both | Same |
| Key difference | The agreement itself is the offence | The agreement is one of three modes by which the person becomes an abettor |
When Conspiracy Ends
A conspiracy is a continuing offence. It subsists as long as the object has not been achieved or abandoned. It ends:
- On achievement of the object
- On abandonment by all conspirators
- On withdrawal by an individual conspirator (communicated and effective)
Withdrawal: A conspirator who communicates his withdrawal to all other conspirators and takes no further part ceases to be liable for subsequent acts. But he remains liable for acts done before his withdrawal.

Key Cases
Kehar Singh v State (Delhi Administration) (1988) Kehar Singh v State Delhi Administration 1988
Issue: Proof of membership in a conspiracy.
Rule: Inferred from conduct, circumstances and acts in furtherance. Each conspirator need not know all details or all identities.
Held: Convicted for conspiracy in the PM's assassination.
State through SP, CBI v Nalini (1999) State through Superintendent of Police CBI v Nalini 1999
Issue: Scope of liability within a conspiracy.
Rule: Every conspirator is liable for every act done by any other in pursuance of the common object.
Held: Later joiners liable for earlier acts in pursuance.
Distinctions
| Basis | Criminal Conspiracy (S.61) | Common Intention (S.3(5)) |
|---|---|---|
| Nature | Substantive offence | Rule of evidence / mode of liability |
| Requires an offence to be committed | No (for serious offences) | Yes; there must be a criminal act done |
| Number | Two or more | Two or more |
| What is punished | The agreement itself | The act done in furtherance of common intention |
| Proof | Agreement inferred from conduct | Common intention inferred from conduct |
| Can stand alone | Yes | No; it is parasitic on a criminal act actually committed |
| Basis | Conspiracy | Attempt |
|---|---|---|
| Stage | Stage 2 (agreement, before any external act towards the offence) | Stage 3 (act beyond preparation, proximate to commission) |
| Parties | Two or more | May be one person |
| Overt act | Not needed for serious offences | Essential; the act must go beyond preparation |
| Focus | The agreement | The individual act towards commission |
Flashcards
Define criminal conspiracy under BNS S.61.
An agreement between two or more persons to do an illegal act, or a legal act by illegal means.
Is an overt act needed for conspiracy to commit murder?
No. Murder is punishable with death or life imprisonment (well above 2 years), so the agreement alone suffices without any overt act.
What is the scope of a conspirator's liability?
Every conspirator is liable for every act done by any co-conspirator in pursuance of the common object (Nalini, 1999).
How is an agreement in a conspiracy proved?
Inferred from conduct, communications, meetings, similarity of action, and acts in pursuance. Direct proof is rarely available (Kehar Singh, 1988).
Can a single remaining accused be convicted of conspiracy if all others are acquitted?
Generally no, because conspiracy requires two or more. But if there are unknown or absconding co-conspirators, the conviction may stand.
What is the punishment for conspiracy to commit an offence punishable with 2+ years?
Same as if the conspirator had abetted the offence (S.61(2)(a)).
Exam Scenario
Problem: Priya, Qasim and Rohan agree over WhatsApp to import a banned substance into India. Priya is to arrange the foreign supplier, Qasim is to provide the funds, and Rohan is to receive the consignment at the port. Before any substance is procured or any funds transferred, the police intercept the messages and arrest all three. No substance has entered India. The prosecution charges them under BNS S.61. They argue that no overt act was done and no offence was committed, so the charge must fail. Advise.
Step 1: Identify the offence that is the object of the conspiracy
The agreement is to import a banned substance. This is punishable under the NDPS Act 1985 with imprisonment of 10 years or more (depending on the quantity). It is an offence punishable with rigorous imprisonment for well above 2 years.
Step 2: Apply the proviso to S.61(1)
| Question | Answer |
|---|---|
| Is the object an offence? | Yes, importing a banned substance is an offence under the NDPS Act |
| Is it punishable with 2 years or more? | Yes, 10 years minimum |
| Does the proviso require an overt act? | No. The proviso requires an overt act only for agreements to do illegal acts that are not offences. For agreements to commit offences, the agreement itself suffices |
The charge under S.61 is made out by the agreement alone.
Step 3: Test the evidence of agreement
The WhatsApp messages disclose:
- Identification of roles (Priya: supplier, Qasim: funds, Rohan: receipt)
- A common object (importation of a banned substance)
- Coordination between three persons
Apply Kehar Singh (1988): the agreement is inferred from the messages and the allocation of roles. Each conspirator need not know every detail.
Step 4: Dispose of the "no offence committed" argument
Criminal conspiracy is an inchoate (incomplete) offence. Its gist is the agreement, not the commission of the object offence. The fact that no substance was procured, no funds were transferred, and no importation occurred is irrelevant.
Under S.61(2)(a), each is punishable as if he had abetted the NDPS offence.
The proviso does not help the accused. It applies only to agreements to do illegal acts that are not offences. An agreement to commit an offence needs no overt act at all. This is the most commonly misread part of S.61.
WhatsApp messages are admissible. Under BSA 2023 S.63 (electronic records), messages extracted under proper certificate are admissible. The defence cannot exclude them on the ground that they are electronic.
Conclusion. The conspiracy is complete on the agreement disclosed in the messages. No overt act is needed. All three are liable under BNS S.61 and punishable as abettors of the NDPS offence.
