Introduction
Under Section 173 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), the law ordinarily prohibits registering multiple First Information Reports (FIRs) for the same cognisable offence or criminal transaction. Any subsequent information regarding an ongoing investigation must be integrated into the existing case file—either recorded as a statement under Section 180 BNSS or examined via further investigation under Section 193(9) BNSS—rather than logged as a fresh FIR.
Judicial Frameworks for Evaluating a Second FIR
Courts look beyond literal wording to evaluate the substance and transactional scope of subsequent allegations using two main legal tests:
The Test of Sameness
If the second FIR arises from the identical occurrence, transaction, or factual matrix as the first, it is barred to prevent investigative overlap and protect Article 21 rights against procedural harassment.
The Consequence Test
If the offence disclosed in the second FIR is merely a natural outcome, continuation, or constituent part of the transaction under investigation, it must be absorbed into the original FIR.
Impermissible Second FIRs vs. Recognised Exceptions
Under Indian criminal law, a second First Information Report (FIR) is strictly impermissible if a subsequent complaint arises from the same incident or transaction already under investigation. In such cases, the new information cannot form a fresh case; it must be absorbed into the existing FIR as part of the ongoing investigation.
Registration of a separate FIR is legally barred if it merely:
- Adds extra details.
- Names additional witnesses.
- Attempts to fix weaknesses in the original complaint.
- Seeks to bypass a police closure report.
Conversely, the law recognises specific exceptional circumstances where registering a valid second FIR is permissible. A fresh FIR can be legally logged if it represents a genuine counter-complaint offering a rival version of the event, concerns a completely distinct and separate incident, or exposes an offence with a fundamentally different scope.
Furthermore, if ongoing disclosures reveal that the initial event was part of a far wider criminal conspiracy or systemic enterprise, police are justified in registering a new, independent FIR.
When a Second FIR Is Impermissible
A subsequent FIR is legally barred and liable to be quashed if it:
Concerns the Identical Transaction
The allegations stem directly from the incident covered by the active investigation.
Amplifies the Original Complaint
It adds details, names new witnesses, or submits further documents for the same occurrence.
Improves the Prosecution Case
It serves to rectify weaknesses or alter the initial factual narrative.
Circumvents an Adverse Report
It responds to a closure report, where the proper legal remedy is a protest petition or private complaint under Section 223 BNSS.
Recognised Exceptions
The Supreme Court reaffirmed key exceptions authorising a second FIR in State of Rajasthan v. Surendra Singh Rathore (2025):
- Counter-Complaints (Rival Versions): Opposing parties in a clash or group clash hold the right to register their distinct versions of the event.
- Distinct Incidents: The complaint details a separate occurrence, even if the accused, complainant, or background context overlap.
- Materially Different Ambit: The scope of the newly disclosed offence differs fundamentally from the initial FIR.
- Larger Conspiracy or New Material: Subsequent findings reveal that the initial incident was merely part of a wider criminal network (e.g., a single bribery allegation expanding into a systemic corruption syndicate).
Standard Police Protocol for Subsequent Complaints
When a police station receives additional information regarding an already registered incident, standard procedure mandates:
- Refraining from generating a new crime/FIR number.
- Logging the details of the complaint into the General/Station Diary.
- Examining the informant under Section 180 BNSS.
- Annexing the complaint to the existing case diary as part of the primary investigation.
Landmark Precedents
| Precedent | Core Legal Principle Established |
|---|---|
| T.T. Antony v. State of Kerala (2001) | Established the foundational bar against a second FIR for the same occurrence. |
| Upkar Singh v. Ved Prakash (2004) | Clarified that the T.T. Antony rule does not bar genuine counter-complaints. |
| Babubhai v. State of Gujarat (2010) | Formalised the “Test of Sameness” for determining transactional overlap. |
| Anju Chaudhary v. State of U.P. (2012) | Affirmed that separate incidents justify independent FIRs despite a shared background. |
| Amitbhai Anilchandra Shah v. CBI (2013) | Held that all offences forming part of a single transaction belong in the primary FIR. |
| State of Rajasthan v. Surendra Singh Rathore (2025) | Synthesised modern exceptions validating second FIRs that reveal distinct ambits or wider conspiracies. |
Legal Remedies
An aggrieved party facing an unlawful second FIR can petition the High Court for quashing under Section 528 BNSS (inherent powers to prevent abuse of process).
Alternatively, relief may be sought through a constitutional writ petition under Articles 226/227 of the Constitution of India.
Conclusion
Modern criminal jurisprudence adheres to the principle that a single transaction warrants only one FIR. This ensures procedural economy and prevents multiplicity of investigations into the same occurrence.
However, where a subsequent complaint discloses a distinct criminal act or unveils a broader conspiracy, the law recognises the legitimacy of a separate investigative mandate.
In such circumstances, registering an independent FIR is not only permissible but fully justified, as it safeguards the integrity of the investigative process and ensures that each offence receives due scrutiny.
