Revisiting Section 120-B of the Indian Penal Code: Substantive and Procedural Dimensions of Criminal Conspiracy

Revisiting Section 120-B of the Indian Penal Code: Substantive and Procedural Dimensions of Criminal Conspiracy

Introduction

Criminal conspiracy, codified in Sections 120-A and 120-B of the Indian Penal Code, 1860 (“IPC”), represents a distinctive inchoate offence that punishes the agreement to commit an unlawful act rather than the completed offence itself. Over the decades, Indian courts have grappled with the contours of this provision, calibrating its scope, evidentiary thresholds, jurisdictional reach, and sentencing principles. This article critically analyses Section 120-B IPC by synthesising leading authorities such as Ram Lal Narang[1], Som Nath Thapa[2], Ajay Agarwal[3], Afsan Guru[4], Kehar Singh[5], and other significant judgments, while interrogating the procedural interfaces under the Criminal Procedure Code, 1973 (“CrPC”) and the Indian Evidence Act, 1872 (“Evidence Act”).

Statutory Framework

Textual Anatomy

Section 120-A defines criminal conspiracy as an agreement between two or more persons to do (1) an illegal act, or (2) a legal act by illegal means. Section 120-B prescribes punishment in two tiers:

  1. Parity of punishment with the substantive offence where the conspiracy relates to offences punishable with death, life imprisonment, or rigorous imprisonment ≥ two years; and
  2. Simple imprisonment up to six months, or fine, or both, for other conspiracies.

Relationship with Other Statutes

The IPC provisions must be read conjunctively with:

  • Section 10, Evidence Act – relevancy of acts and statements of co-conspirators;
  • Sections 154, 156, 173 & 173(8), CrPC – investigation reports and further investigation;
  • Sections 196 & 196-A, CrPC – sanction/consent prerequisites for certain conspiracies;
  • Special statutes (e.g., POTA, TADA, PC Act) that create aggravated forms of conspiracy.

Essential Ingredients and Evidentiary Thresholds

Agreement and Mens Rea

The Supreme Court in Som Nath Thapa distilled two indispensable elements:

“(i) an agreement between two or more persons, and (ii) the agreement must be to do an illegal act or a legal act by illegal means.”[2]
Knowledge and intentional participation, not mere association, are therefore vital. The Court clarified that mens rea may be inferred from circumstantial evidence; overt acts, though probative, are not sine qua non in conspiracies to commit serious offences.

Section 10, Evidence Act: The Co-conspirator’s Exception

Section 10 admits statements or acts of one conspirator against all, provided there is “reasonable ground to believe” in the existence of the conspiracy. K. Hashim emphasised that this provision enlarges admissibility temporally—from the genesis of the design until its termination—thus capturing preparatory and concealment acts.[18] However, the Court in Afsan Guru cautioned against wholesale importation of the “agency theory” and insisted on independent corroboration when confessions are invoked against co-accused under special statutes.[4]

Confessions and Accomplice Evidence

While Section 133, Evidence Act permits conviction on uncorroborated accomplice testimony, prudential practice—as reiterated in State through CBI v. Nalini[6]—demands corroboration, especially when a death sentence is in contemplation (Kehar Singh).[5]

Procedural Architecture

Sanction and Consent under Sections 196 & 196-A CrPC

For conspiracies falling within Section 196(2)—i.e., those linked to offences punishable with less than two years or non-cognisable offences—previous written consent of the State Government or District Magistrate is mandatory. The Delhi High Court in Rahul Kanwal quashed proceedings where such consent was absent for a conspiracy to commit criminal trespass, an offence punishable below the statutory threshold.[21] Conversely, conspiracies to commit serious offences (≥ two years’ punishment) bypass this filter, thereby facilitating prompt prosecution.

Investigative Autonomy and Further Investigation

In the Suraj Kund pillars case, the Supreme Court upheld successive investigations, holding that police are empowered under Section 173(8) CrPC to pursue fresh leads without prior judicial leave when new conspiracies emerge.[1] This doctrine preserves investigative flexibility in complex, multi-layered conspiracies.

Framing of Charge

At the charge stage, courts merely ascertain a prima facie case. Som Nath Thapa enunciated that if materials, taken at face value, disclose the ingredients of Section 120-B, charges must follow; disputed factual issues are reserved for trial.[2]

Cross-Border Conspiracies and Jurisdiction

Ajay Agarwal confirmed that conspiracy is a “continuing offence”. Where part of the agreement or overt acts occur in India, domestic courts have jurisdiction without Central Government sanction under Section 188 CrPC.[3] The judgment strengthens India’s ability to tackle trans-national economic and terror conspiracies.

Substantive–Procedural Interplay: Selected Themes

Multiplicity of Conspiracies

Ram Lal Narang recognised that a single factual matrix can harbour discrete conspiracies distinguished by objectives, actors, or chronology. This permits separate trials where justice so demands, without violating Article 20(2) (double jeopardy).[1]

Sentencing Philosophy

Although Section 120-B imports the punishment of the principal offence, judicial discretion is guided by gravity, role differentiation, and the rarest-of-rare doctrine in capital cases (Kehar Singh).[5] Where the conspiracy is the sole offence (second limb of § 120-B), proportionality prevails, often resulting in nominal sentences or fine, as seen in minor commercial disputes (Hari Om Bhatia).[23]

Corporate and Media Offences

Recent cases (e.g., Aveek Sarkar[22]) showcase the deployment of Section 120-B against corporate entities and media houses for allegedly offensive advertisements. Courts have insisted on proof of a concerted agreement among directors or editorial staff, not mere vicarious liability.

Intersection with Special Legislations

Special statutes frequently superimpose aggravated conspiracy provisions (e.g., Section 3(3) POTA, Section 18 UAPA). Nonetheless, prosecutors often retain Section 120-B as a back-up charge. In Afsan Guru, conspiracy to wage war under Section 121 IPC was read with Section 120-B to capture preparatory acts that POTA did not fully cover.[4] Similarly, corruption prosecutions under the Prevention of Corruption Act, 1988 routinely invoke Section 120-B to rope in non-public-servant facilitators (P.V. Narasimha Rao).[10]

Doctrinal Critiques and Emerging Challenges

  • Over-Breadth Concerns: Scholars argue that the low threshold—mere agreement—risks criminalising political dissent or legitimate advocacy when coupled with broad special statutes. Judicial vigilance in requiring intent and knowledge mitigates, but does not eliminate, this risk.
  • Digital Conspiracies: Online collaborative spaces complicate the evidentiary nexus. Metadata, encrypted communications, and cross-border servers challenge traditional Section 10 analyses, necessitating nuanced jurisprudence on electronic evidence.
  • Plea Bargaining and Settlements: High Courts increasingly quash Section 120-B charges pursuant to settlements in commercial disputes (Hari Om Bhatia), invoking the Supreme Court’s guidance in Duncan’s Agro that continuance of prosecution may be oppressive.[27]

Conclusion

Section 120-B IPC remains a potent prosecutorial tool, equally capable of dismantling terror networks and combating systemic corruption. Its jurisprudential evolution demonstrates a delicate judicial balance—expanding reach to counter sophisticated criminal collaborations while embedding safeguards through stringent mens rea requirements, procedural filters, and evidentiary prudence. Future challenges will revolve around digital conspiracies, cross-border enforcement, and reconciling the provision’s breadth with civil liberties. A principled, context-sensitive application, as illustrated by the Supreme Court’s leading precedents, is essential to preserve the legitimacy and effectiveness of India’s conspiracy law.
