Criminal Conspiracy Under Section 120B IPC: Law, Punishment, and Defence 2026

Criminal conspiracy is one of the most frequently invoked charges in Indian criminal law. Defined under Section 120A IPC and punishable under Section 120B IPC, criminal conspiracy allows the prosecution to charge multiple persons who agreed to commit an offence, even if the actual offence was not committed. If you face conspiracy charges, understanding Section 120B IPC is essential for your defence.

This guide explains the law of criminal conspiracy, essential ingredients, punishment, landmark judgments, and defence strategies. For legal help, connect with experienced criminal lawyers on WakilSearch or search for lawyers in Delhi specialising in criminal defence.

What is Criminal Conspiracy Under Section 120A IPC?

Section 120A IPC defines criminal conspiracy: when two or more persons agree to do an illegal act, or a legal act by illegal means, such agreement is designated a criminal conspiracy. No overt act is necessary — the agreement itself is the offence. This makes conspiracy a uniquely powerful charge because the prosecution does not need to prove the conspired act was actually carried out.

The two essential ingredients are: (1) an agreement between two or more persons, and (2) the agreement must be to do an illegal act or a legal act by illegal means. The agreement can be express or implied from conduct. Conspirators need not have met physically — communication through intermediaries, phone calls, messages, or signals is sufficient. The Supreme Court has held that conspiracy is almost always proved by circumstantial evidence because conspirators rarely leave direct evidence.

Punishment Under Section 120B IPC

Section 120B(1) deals with conspiracy to commit a punishable offence. Punishment is the same as for abetment of the offence that was the conspiracy's object. If the conspired offence is punishable with death, life imprisonment, or rigorous imprisonment of 2+ years, the conspiracy punishment equals the abetment punishment. Section 120B(2) covers other conspiracies — imprisonment up to 6 months or fine or both.

In Kehar Singh v. State (Delhi Administration) (1988) — the Indira Gandhi assassination case — the Supreme Court held that conspirators need not know or meet each other. A single meeting or communication can establish conspiracy if parties agree to a common design. For serious cases, connect with criminal lawyers in Mumbai through WakilSearch.

How Criminal Conspiracy Cases Progress

Stage 1: Registration of FIR

The police register an FIR under Section 120B IPC along with the substantive offence (murder, fraud, cheating). Conspiracy is often added to cast a wider net and include all persons involved in planning or facilitating the crime.

Stage 2: Investigation and Arrest

Police investigate by collecting call records, messages, emails, witness statements, financial transactions, and circumstantial evidence linking the accused. Conspiracy charges are often non-bailable.

Stage 3: Filing of Charge Sheet

Police file a charge sheet under Section 173 CrPC including Section 120B with the substantive offence, disclosing the particulars of the conspiracy — the agreement, parties, timing, and illegal act agreed upon.

Stage 4: Framing of Charges

The court frames charges under Section 120B read with the substantive offence. The charge must be specific about each accused's role and the common object of the conspiracy.

Stage 5: Trial and Evidence

The prosecution presents evidence through: CDR data, call records, intercepted communications, witness testimony about meetings, financial transactions, emails, and conduct evidence. Circumstantial evidence is the primary means of proving conspiracy.

Landmark Judgments on Criminal Conspiracy

Major E.G. Barsay v. State of Bombay (1961) — The essence of conspiracy is the agreement. It need not be formal — it can be inferred from conduct. Each conspirator need not know all details; knowledge of the essential purpose is sufficient.

State of Tamil Nadu v. Nalini (1999) — The Rajiv Gandhi assassination case: once conspiracy is established, every act by any conspirator in furtherance of the common intention is attributable to all. Liability is joint and several.

R. Venkatakrishnan v. CBI (2009) — The prosecution must prove the accused had a common intention or purpose. Mere suspicion or possibility of conspiracy is not enough.

Yogesh Singh v. State of Gujarat (2016) — Criminal conspiracy requires positive proof of agreement. If the accused merely knew about the crime but did not actively participate, they cannot be convicted under Section 120B.

Documents Required in Conspiracy Cases

• FIR and Charge Sheet — Primary documents setting out the prosecution case. The FIR must disclose conspirator names and the conspiracy nature.
• Call Detail Records (CDR) — Cell phone tower data and call logs showing communication between alleged conspirators. CDRs prove communication, not the content.
• Financial Records — Bank statements, money transfers, and cheque payments indicating conspiracy funding or proceeds sharing.
• Emails and Messages — WhatsApp chats, SMS, emails discussing the conspiracy. Must be authenticated under Section 65B Evidence Act.
• Witness Statements — Statements of witnesses claiming knowledge of conspiracy, meetings, or communications between accused persons.
• Surveillance Records — Phone tapping (if legally obtained), CCTV footage, and surveillance reports placing accused together at relevant times.

Frequently Asked Questions About Criminal Conspiracy

1. What is the difference between conspiracy and abetment?

Criminal conspiracy (Section 120A/120B) requires an agreement between two or more persons to commit an illegal act. Abetment (Section 107 IPC) involves instigating, engaging in a conspiracy, or intentionally aiding the commission of an offence. A person can be charged with both for the same incident.

2. Can a person be convicted only under Section 120B?

Yes. The Supreme Court has held that a person can be convicted of conspiracy even if the substantive offence was not committed, as long as the agreement is proved. However, if the substantive offence is proved, the conspiracy charge may merge.

3. What evidence is needed to prove conspiracy?

Circumstantial evidence primarily: call records, witness testimony about meetings, financial transactions, and conduct of parties. The evidence must show a clear meeting of minds — mere suspicion is insufficient.

4. Is bail available in conspiracy cases?

It depends on the substantive offence. If the conspired offence is bailable, the conspiracy charge is bailable. If non-bailable (murder, fraud), the conspiracy charge is also non-bailable.

5. How many people are needed for a conspiracy?

A minimum of two persons is required. If only one accused remains after acquittals, the conspiracy charge fails because there is no agreement. However, conviction of one can stand if the acquitted person was an unindicted co-conspirator.

6. Can a husband and wife be charged with conspiracy?

Yes. There is no marital exemption for conspiracy in India. However, courts are cautious about charging spouses without clear evidence of a criminal agreement.

7. What if no specific offence was committed?

Under Section 120B(1) — if the conspired offence is punishable with 2+ years, the punishment equals abetment of that offence. Under Section 120B(2) — for other conspiracies, imprisonment up to 6 months or fine.

Practical Tips for Defending Conspiracy Charges

Challenge digital evidence. CDRs must be obtained under proper procedure and authenticated under Section 65B Evidence Act. Challenge admissibility if proper certification is missing. Argue that communication does not prove the content or purpose.

Attack witness credibility. Conspiracy cases often rely on accomplice testimony. Cross-examine thoroughly to expose inconsistencies and motives. Accomplice testimony requires independent corroboration under Section 133 Evidence Act.

Argue mere association is not conspiracy. Mere presence at meetings or knowledge without active participation is insufficient. The prosecution must prove a clear meeting of minds.

File for discharge early. If the charge sheet lacks sufficient grounds, file a discharge application under Section 227 or 239 CrPC.

Conclusion

Criminal conspiracy under Section 120B IPC is a powerful but often misused charge. The prosecution only needs to prove an agreement — not the actual commission.
