Criminal Conspiracy Under BNS: Legal Framework, Key Elements, and Landmark Judgments

Introduction

With the coming into force of India’s new criminal law framework on July 1, 2024, the substantive law of crimes transitioned from the Indian Penal Code, 1860 (IPC) to the Bharatiya Nyaya Sanhita, 2023 (BNS). While the procedural mechanisms are now governed by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) and evidentiary standards by the Bharatiya Sakshya Adhiniyam, 2023 (BSA), the doctrine of inchoate offences—crimes that are committed in anticipation of or in preparation for another crime—remains a cornerstone of prosecution strategy.

Among these, criminal conspiracy holds a unique position. Conspiracies are hatched in secrecy, often executed by degrees, and rarely documented in black and white. This guide examines the statutory architecture of criminal conspiracy under Section 61 of the BNS, analyzes its indispensable legal ingredients, looks at the rules of evidence under the BSA, and surveys key judicial precedents that continue to define the contours of this offence.

Statutory Framework: Section 61 of the Bharatiya Nyaya Sanhita, 2023

Under the erstwhile regime, criminal conspiracy was bifurcated into definition and punishment under Sections 120A and 120B of the IPC. The BNS consolidates these into a single provision: Section 61.

1. Definition (Section 61(1) BNS)

Section 61(1) defines criminal conspiracy as follows:

When two or more persons agree 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.

The Proviso to Section 61(1) provides a critical distinction:

If the agreement is to commit an offence, the mere agreement itself constitutes the offence of criminal conspiracy. No overt act is needed.
If the agreement is to perform an illegal act that does not amount to an offence, or an act done by illegal means, an overt act performed by one or more parties in pursuance of the agreement is mandatory to complete the crime.

2. Punishment (Section 61(2) BNS)

The penal sanctions mirror the earlier framework of Section 120B IPC:

Section 61(2)(a): Conspiracy to commit an offence punishable with death, imprisonment for life, or rigorous imprisonment for a term of two years or upwards (where no express provision is made in the BNS for its punishment) is punished in the same manner as if the conspirator had abetted such offence.
Section 61(2)(b): Conspiracy to commit any other offence is punishable with imprisonment of either description for a term not exceeding six months, or with fine, or with both.

Core Ingredients of Criminal Conspiracy

To establish an offence under Section 61 of the BNS, the prosecution must discharge the burden of proving specific legal ingredients beyond reasonable doubt:

1. Plurality of Persons

A person cannot conspire with themselves. There must be at least two distinct individuals. If multiple individuals are charged with conspiracy and all except one are acquitted on the merits, the remaining accused cannot stand convicted of conspiracy alone, unless there is unindicted or absconding co-conspirators established on record.

2. Meeting of Minds (Consensus Ad Idem)

The essence of criminal conspiracy is the agreement. A mere intention, uncommunicated desire, or parallel independent thoughts do not constitute conspiracy. There must be a physical or intellectual consensus between two or more parties to embark on an unlawful course of action.

3. Common Design and Unlawful Objective

The agreement must center upon committing an illegal act (defined under Section 2(15) of the BNS as anything which is an offence, or which is prohibited by law, or which furnishes ground for a civil action) or achieving an act by illegal means.

4. The Need (or Absence) of an Overt Act

Where the target of the conspiracy is a statutory offence (e.g., murder, extortion, fraud, cyber-attacks), the crime of conspiracy is complete the moment the unlawful agreement is struck. The law intervenes at the stage of contemplation-turned-agreement to prevent societal harm.

Proving the Inchoate Crime: Evidentiary Rules Under the BSA, 2023

Because criminal conspiracies are almost always hatched behind closed doors, direct evidence (such as signed contracts or direct eyewitnesses to the secret meeting) is seldom available. The prosecution primarily relies on circumstantial evidence.

Section 8 of the Bharatiya Sakshya Adhiniyam, 2023

Section 8 of the BSA (which replaces Section 10 of the Indian Evidence Act, 1872) embodies the doctrine of agency among conspirators:

Threshold Requirement: There must first exist reasonable ground to believe that two or more persons have conspired together.
Statutory Effect: Once that threshold prima facie evidence exists, anything said, done, or written by any one of such persons in reference to their common intention (after the intention was first entertained by any one of them) is a relevant fact against each of the persons believed to be so conspiring, both for proving the existence of the conspiracy and for showing that any such person was a party to it.

This principle allows acts or communications of one conspirator—such as financial trails, call records, encrypted messages, or travel manifests—to be read into evidence against co-conspirators, subject to strict procedural compliance.

Landmark Judgments on Criminal Conspiracy

Although enacted under the IPC, the jurisprudence articulated by the Supreme Court of India remains fully authoritative when interpreting Section 61 of the BNS:

1. Kehar Singh and Others v. State (Delhi Administration) (1988)

The Supreme Court observed that the most important ingredient of the offence being the agreement between two or more persons, it is rarely possible to produce direct evidence of meeting of minds. Conspiracy can be inferred from the surrounding circumstances, conduct of the parties before and after the incident, and coordinated actions that indicate a shared pre-arranged plan.

2. State (NCT of Delhi) v. Navjot Sandhu (2005) (Parliament Attack Case)

The Apex Court held that a tacit understanding between conspirators is sufficient. Conspirators do not need to be in direct contact with every other member of the conspiracy throughout its execution. A conspiracy may be continuous; members may join or leave at different stages. However, the Court cautioned that suspicion, however grave, cannot substitute legal proof of an agreement.

3. Topandas v. State of Bombay (1955)

The Supreme Court settled the principle that one individual alone cannot be convicted of criminal conspiracy if all other alleged co-conspirators on trial are acquitted, in the absence of proof of unnamed or unknown conspirators involved in the common scheme.

4. Central Bureau of Investigation v. V.C. Shukla (1998)

The Court reaffirmed that mere association or frequent meetings between individuals do not automatically establish a criminal conspiracy unless there is evidence connecting their association to the unlawful agreement.

Procedural Safeguards and Defences

Navigating an accusation of criminal conspiracy under the BNS and the BNSS requires an understanding of the common defences available under Indian criminal law:

Mere Knowledge vs. Agreement: Having knowledge of an illegal act is not equivalent to agreeing to participate in it. If a person was an unwitting participant or merely aware of another’s unlawful designs, Section 61 does not apply.
Break in the Chain of Circumstantial Evidence: When the case rests on circumstantial evidence under Section 8 of the BSA, the prosecution must establish a chain of events so complete that it rules out every reasonable hypothesis of innocence.
Discharge Prior to Trial: Under the BNSS, an accused may seek discharge before framing of charges if the prosecution fails to establish a prima facie meeting of minds, preventing protracted and prejudicial trials.

Frequently Asked Questions (FAQs)

1. Is an overt act always required to prove criminal conspiracy under Section 61 of the BNS?

No. If the objective of the conspiracy is to commit an offence (such as theft, cheating, or assault), the agreement itself completes the crime. An overt act is required only if the illegal act agreed upon does not amount to an offence.

2. How does Section 61 of the BNS differ from Section 120A/120B of the IPC?

The substantive definition and the quantum of punishment remain largely aligned. However, the BNS combines the definition and the penal clauses under a single statutory provision (Section 61), streamlining references in investigation reports, FIRs, and charge sheets.

3. Can a person be charged with criminal conspiracy if they joined the plot at a later stage?

Yes. Under settled criminal jurisprudence, a conspirator does not need to have been part of the conspiracy from its inception. A person who joins an existing conspiracy with knowledge of its common design becomes liable for acts committed in furtherance of that design thereafter.

4. How can digital evidence (like WhatsApp or email communications) be used to prove conspiracy under the new laws?

Digital communications are governed by the Bharatiya Sakshya Adhiniyam, 2023. Electronic records are admissible to demonstrate the meeting of minds and coordinated actions, provided they comply with statutory requirements for electronic records and certification under the BSA.
