Kehar Singh & Others v. State (Delhi Administration)
Bench: Constitution Bench — 5 Judges (R.S. Pathak CJ, E.S. Venkataramiah, S. Natrajan, O. Chinnappa Reddy & S.C. Agarwal JJ)
Parties
Facts of the Case
Kehar Singh, Balbir Singh, and Satwant Singh were convicted for the assassination of Prime Minister Indira Gandhi on 31 October 1984. Satwant Singh was her bodyguard and shot her; Kehar Singh was convicted as a conspirator under Section 120B IPC. The key question before the Constitution Bench was the law on criminal conspiracy — what level of participation and knowledge is required to be a co-conspirator in a murder, and whether the circumstantial evidence was sufficient to prove Kehar Singh's role as a conspirator.
Legal Issues Before the Court
- 1What constitutes criminal conspiracy under Section 120A IPC / BNS Section 61?
- 2What evidence is sufficient to prove participation in a conspiracy — must every conspirator know all the details of the plan?
- 3What is the standard for inferring conspiracy from circumstantial evidence?
The Judgment
The Supreme Court upheld the conviction and death sentence of Kehar Singh, holding that a conspiracy can be inferred from circumstances — direct evidence of an agreement is not required. The Court laid down that a conspirator need not know every detail of the conspiracy; it is sufficient if they know the general nature and object of the conspiracy and agree to further its execution.
Key Principles Laid Down
CONSPIRACY CAN BE PROVED CIRCUMSTANTIALLY: There is rarely direct evidence of a conspiratorial agreement — courts can infer a conspiracy from the conduct of the parties, their relations with each other, and the acts done in furtherance of the common object. Circumstantial evidence is sufficient.
CONSPIRATOR NEED NOT KNOW ALL DETAILS: It is not necessary for every co-conspirator to be aware of every detail of the plan. What is required is that the accused knew the general nature and criminal object of the conspiracy and agreed to participate in furthering it.
ACT OF ONE IS ACT OF ALL CO-CONSPIRATORS: Once a person is found to be a member of a conspiracy, every act done by any co-conspirator in furtherance of the common object is attributable to all members of the conspiracy — even if a particular member did not participate in that specific act.
SECTION 10 IEA — ANYTHING SAID OR DONE BY CO-CONSPIRATOR: Under Section 10 IEA (BSA Section 10), once there is reasonable ground to believe a conspiracy existed, anything said or done or written by any one of the conspirators in reference to their common intention is admissible against all co-conspirators.
AGREEMENT IS THE ESSENCE OF CONSPIRACY: The gravamen of Section 120A / BNS Section 61 is the agreement between two or more persons to do an unlawful act. The offence is complete as soon as the agreement is formed — even before any overt act is committed.
Impact on Indian Law
Kehar Singh is the foundational authority on criminal conspiracy under Section 120A/120B IPC / BNS Section 61. The principles — circumstantial proof, no need to know all details, common intention liability — are cited in every major conspiracy case: terrorism cases, organised crime prosecutions, and political assassination trials. The case is also historically significant as involving the assassination of a Prime Minister and the subsequent communal violence. The BNS 2023's Section 61 retains the conspiracy framework with substantively similar language.
Frequently Asked Questions
What are the elements of criminal conspiracy under Section 120A IPC / BNS Section 61?
Criminal conspiracy under Section 120A IPC / BNS Section 61 requires: (1) an agreement between two or more persons; (2) to do an illegal act, or to do a legal act by illegal means. The offence is complete the moment the agreement is formed — no overt act is needed (though overt act is required for conspiracy to commit offences other than those punishable with death, life, or two years' imprisonment). Per Kehar Singh, a conspirator need not know all details — knowledge of the general criminal object is sufficient.
Can conspiracy be proved without direct evidence of a meeting or agreement?
Yes. Kehar Singh (1988) held that conspiracy can be proved entirely from circumstantial evidence — the conduct of the parties, their associations, communications, and acts done in furtherance of the common design. Courts regularly convict persons for conspiracy based solely on circumstantial evidence without any direct proof of an explicit agreement.
