Introduction
Whether registration of a First Information Report (FIR) is an indispensable precondition for commencing a criminal investigation is an important question in Indian criminal procedure. The Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which replaced the Code of Criminal Procedure, 1973 (CrPC), largely retains the established principle that registration of an FIR ordinarily precedes a formal police investigation into a cognizable offense. However, this principle is not absolute. The BNSS expressly recognizes a limited preliminary inquiry in certain cases, while judicial precedents have also permitted narrowly defined investigative or verification measures before formal registration.
FIR as the Normal Starting Point of Investigation
An FIR is the formal mechanism through which information relating to a cognizable offense is brought to the police record. Section 173 of the BNSS, corresponding broadly to Section 154 of the CrPC, governs the recording of information relating to cognizable offenses.
Where the information clearly discloses the commission of a cognizable offense, the police ordinarily have a statutory duty to register the FIR. Once registered, the police acquire the formal authority to proceed with investigation in accordance with the provisions of the BNSS.
Thus, the general procedural sequence is
Information → FIR Registration → Investigation → Final Report/Charge Sheet
This sequence promotes transparency, accountability, and judicial oversight of police action.
The Supreme Court’s Approach: Lalita Kumari
The leading authority remains Lalita Kumari v. Government of Uttar Pradesh (2014) 2 SCC 1, in which the Constitution Bench of the Supreme Court held that registration of an FIR is mandatory where the information discloses a cognizable offense.
The Court, however, recognized that in certain situations a limited preliminary inquiry may be conducted to determine whether the information actually discloses a cognizable offense. The Court identified illustrative categories such as
- Matrimonial and family disputes;
- Commercial offenses;
- Medical negligence cases;
- Corruption cases; and
- Cases involving abnormal delay in reporting.
The purpose of such an inquiry is not to determine the truth or falsity of the allegations in depth, but only to ascertain whether a cognizable offense is disclosed. It cannot be converted into a full-fledged investigation before registration of the FIR.
The Important Change Under Section 173(3) BNSS
The BNSS has introduced an important statutory development through Section 173(3). Where information relating to a cognizable offense is punishable with imprisonment for three years or more but less than seven years, the officer in charge may, with the prior permission of an officer not below the rank of Deputy Superintendent of Police, conduct a preliminary inquiry to ascertain whether a prima facie case exists.
The inquiry is required to be completed within fourteen days, subject to such further time as may be permitted in accordance with law.
This provision is significant because it places a form of preliminary inquiry expressly within the statutory framework. It therefore represents an important development from the predominantly judge-made safeguards articulated in Lalita Kumari.
Can Police Act Before Registration of an FIR?
The answer requires a distinction between preliminary verification or urgent protective measures and a formal statutory investigation.
Police officers may, depending upon the circumstances and the applicable statutory provisions, take immediate steps to secure a crime scene, prevent further harm, preserve evidence, or respond to an emergency. Such action should not automatically be equated with the commencement of a full-fledged investigation.
The Supreme Court’s decision in State of U.P. v. Bhagwant Kishore Joshi, AIR 1964 SC 221, illustrates the distinction between a formal investigation and preliminary steps taken to verify information. Not every preliminary act performed by the police before registration of a formal case necessarily invalidates subsequent proceedings.
Similarly, in Sirajuddin v. State of Madras (1971) 1 SCC 595, the Supreme Court recognized the desirability of a preliminary inquiry in appropriate cases, particularly where allegations against public servants could have serious reputational consequences.
The Earlier Principle in Khwaja Nazir Ahmad
The Privy Council’s decision in Emperor v. Khwaja Nazir Ahmad, AIR 1945 PC 18, remains an important authority concerning the broad investigative powers of the police in cognizable cases. The judgment emphasized the statutory character of police investigation and the limited role of courts in interfering with the investigation process.
The decision must, however, be understood in the context of the statutory scheme prevailing at that time. Under the present BNSS framework, the provisions governing registration, preliminary inquiry, and investigation must be read together.
FIR and Formal Investigation: An Important Distinction
It is therefore useful to distinguish between three different stages:
7.1. Preliminary Receipt and Verification of Information
The police may receive information, assess its nature, and, where legally permitted, conduct a limited preliminary inquiry.
7.2. Registration of the FIR
Where the information discloses a cognizable offense—or where the statutory preliminary inquiry establishes a prima facie case—the FIR is registered.
7.3. Formal Investigation
Following registration, the police exercise the investigative powers provided by the BNSS, including examination of witnesses, searches, seizures, collection of evidence, arrests where legally justified, and preparation of the final report.
The mere fact that some police action occurred before registration does not necessarily mean that the entire subsequent investigation is unlawful. The legality of the particular action depends upon its nature, purpose, statutory authority, and the circumstances in which it was undertaken.
7.4. Summary
| Situation | Is FIR Registration Normally Required First? | Position Under Law |
|---|---|---|
| Information clearly discloses a cognizable offense. | Yes. | Section 173(1) BNSS; Lalita Kumari |
| Offense punishable with 3 to less than 7 years | Not necessarily | Limited preliminary inquiry under Section 173(3) BNSS |
| Matrimonial/family, commercial, medical negligence, corruption, etc. | Limited inquiry may be permissible. | Lalita Kumari |
| Immediate preservation of evidence or emergency police response | Not necessarily | Depends on the nature and statutory basis of the action |
| Full-fledged formal investigation | Ordinarily, yes. | Governed by the investigation provisions of the BNSS |
8. Immediate Action Before FIR
Where the police receive credible information that an attempt to murder is in progress, they need not wait for formal registration of an FIR before rushing to the place of occurrence. The immediate priority is to protect and rescue the victim, prevent further violence, apprehend the offender where legally justified, secure the scene, and preserve vital evidence. Such urgent protective measures are distinct from the commencement of a full-fledged formal investigation.
Once the immediate emergency is controlled and the information discloses a cognizable offense, the police should promptly register the FIR and commence the investigation in accordance with the BNSS, 2023. Thus, in an ongoing life-threatening situation, immediate police intervention before FIR registration is legally permissible and, in appropriate circumstances, may be necessary, but it cannot be used to justify an indefinite delay in recording the FIR or conducting an unrestricted investigation without following the statutory procedure.
In Lalita Kumari v. Government of U.P. (2014) 2 SCC 1, the Supreme Court held that registration of an FIR is mandatory whenever information discloses a cognizable offense and cannot be delayed by an unnecessary preliminary inquiry. However, urgent police action needed to protect life, stop an ongoing offense, or preserve evidence need not await formal FIR registration. Such measures must be promptly followed by FIR registration and cannot justify indefinite delay or a full investigation outside the statutory procedure.
Conclusion
Registration of an FIR remains the normal and legally significant starting point for a formal police investigation into a cognizable offense, particularly where the information clearly discloses such an offense. However, it is not an inflexible precondition to every police action. Lalita Kumari established the mandatory-registration principle while permitting narrowly confined preliminary inquiries, and Section 173(3) BNSS has now expressly incorporated a limited preliminary inquiry mechanism for specified offenses punishable with three years or more but less than seven years.
The correct legal position, therefore, is not simply that “no FIR means no investigation.” Rather, the law distinguishes between preliminary verification, urgent protective or evidentiary measures, and a formal statutory investigation. The BNSS seeks to maintain this balance by ensuring that genuine cognizable offenses are promptly registered while allowing limited preliminary scrutiny where the statute or established judicial principles justify it.
