Statutory Definition
Defined in Section 173 of BNSS 2023.
Etymology & Origin
An acronym coined in colonial Indian police administration — First Information Report — to describe the first written information received by the police about the commission of a cognizable offence. The concept is rooted in the CrPC's framework distinguishing cognizable offences (where police can act without a magistrate's order) from non-cognizable offences. The FIR procedure was codified in the Code of Criminal Procedure and has been preserved in the Bharatiya Nagarik Suraksha Sanhita, 2023.
Full Legal Analysis
A First Information Report (FIR) is the first written information given to the officer in charge of a police station regarding the commission of a cognizable offence. It sets the criminal law process in motion — once a cognizable offence is reported, the police officer is mandatorily required to register it, commence investigation, and report to the Magistrate. The FIR is the foundation of the entire criminal prosecution: it defines the offence, the accused (if known), and the circumstances, and any significant departure from it during trial must be explained.
The mandatory nature of FIR registration for cognizable offences was definitively established by the Supreme Court in Lalita Kumari. Prior to this judgment, police officers frequently refused to register FIRs in serious cases — particularly dowry death, rape, and land-related offences — either due to local influence or under pressure from the accused. The Supreme Court held that registration is not discretionary: if the information discloses a cognizable offence on its face, registration is mandatory. Preliminary inquiry may be conducted only in specific exceptional categories (matrimonial disputes, commercial offences, corruption cases) before registration.
The FIR is not substantive evidence in the trial — it is a previous statement of the informant that can be used to corroborate or contradict them when they testify as a witness. However, it is a vital investigative document: the time of the FIR, the names of accused mentioned, and the nature of the offence alleged are all examined closely by courts. A delayed FIR in a serious offence raises a presumption of fabrication that the prosecution must explain. An FIR that specifically names the accused is given greater weight than one that names only one accused and adds others later.
The Supreme Court Constitution Bench held that registration of FIR is mandatory under Section 154 CrPC when the information discloses a cognizable offence. The police officer has no discretion to refuse registration. Failure to register an FIR amounts to dereliction of duty and the officer is liable to departmental and criminal action. A preliminary inquiry before registration is permitted only in certain categories — matrimonial/family disputes, commercial offences, medical negligence — and must be completed within seven days.
The concept of the Zero FIR was formalised through the BNSS 2023. A Zero FIR is one registered at a police station that does not have territorial jurisdiction over the offence — the FIR is registered immediately, given a zero serial number, and transferred to the appropriate police station. This is particularly important in cases of rape, kidnapping, and other urgent offences where the victim should not be required to travel to the jurisdictionally correct station before registering the complaint.
Advocates representing complainants in serious criminal cases must know the FIR registration procedure thoroughly. If police refuse to register an FIR, the appropriate remedy is: (1) written complaint to the Superintendent of Police (Section 154(3) CrPC / Section 173(4) BNSS); (2) application to the Magistrate for direction to register (Section 156(3) CrPC / Section 175(3) BNSS); or (3) writ petition to the High Court under Article 226. The High Court routinely directs FIR registration in appropriate cases where lower authorities have failed to act.
