First Information Report (FIR): Meaning, Section 173 BNSS & Rights

Study Notes · General Studies

UPSC guide to First Information Report — BNSS Section 173, Zero FIR, e-FIR, Lalita Kumari ruling, rights of complainants, and remedies on refusal.

A First Information Report (FIR) is the written document prepared by the police on receiving the first information relating to the commission of a cognizable offence. It sets the criminal justice process in motion — without an FIR, the police cannot, as a rule, begin a formal investigation into a cognizable offence. The FIR is the foundation document on which the investigation, charge sheet and subsequent trial rest.

From 1 July 2024, the FIR is governed by Section 173 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) — the new criminal procedure law that replaced the Code of Criminal Procedure, 1973 (CrPC), in which the corresponding provision was Section 154. The change is procedural: the substance of what an FIR is, who can file one, and the citizen's rights remain broadly the same.

What is an FIR? (Definition and Essentials)

The term "First Information Report" is not defined in the BNSS or the erstwhile CrPC. Judicial decisions have identified four essentials:

  1. It must be information — not a conclusion.
  2. It must relate to the commission of a cognizable offence.
  3. It must be the first in point of time.
  4. It must be reduced to writing and signed by the informant.

The report is entered verbatim in the First Information Book maintained at the police station; a free copy must be handed to the informant.

Cognizable vs Non-Cognizable Offences

FeatureCognizable OffenceNon-Cognizable Offence
Police can arrest without warrantYesNo
Police can investigate without magistrate's orderYesNo — requires Section 174 BNSS order
InstrumentFIR (Sec 173 BNSS)NCR — Non-Cognizable Report (Sec 174 BNSS)
ExamplesMurder, rape, dowry death, robbery, dacoityDefamation, mischief, cheating (under certain thresholds), assault (simple)

Cognizable offences are listed in the First Schedule of BNSS and generally carry imprisonment of three years or more.

Section 173 BNSS — Key Provisions

173(1) — Receipt of Information

Every information relating to the commission of a cognizable offence, whether oral or written, shall be reduced to writing, read over to the informant, signed, and entered in the station diary.

173(1) Proviso — Gender-Sensitive Provisions

For offences under Sections 64–71, 74–79, 124 BNS (rape, sexual harassment, voyeurism, stalking, etc.), information shall be recorded by a woman police officer, and — if the victim is physically or mentally disabled — at the victim's residence, with a legal aid lawyer and video recording.

173(2) — Copy to Informant

A copy of the FIR shall be given free of cost and forthwith to the informant.

173(3) — New Provision — Preliminary Enquiry

A major change introduced by BNSS: for offences punishable with imprisonment of three to seven years, the police officer may — with prior permission from a superior officer (not below DSP) — conduct a preliminary enquiry within 14 days to ascertain whether a prima facie case exists, before registering the FIR.

173(4) — Refusal Remedy

If the SHO refuses to register an FIR, the informant may send the substance of the information in writing, by post, to the Superintendent of Police (SP), who shall either investigate or direct investigation.

175 BNSS — Magistrate's Power

If the SP also refuses, the informant may approach the Judicial Magistrate under Section 175(3) BNSS (earlier Sec 156(3) CrPC). The Magistrate may order registration and investigation after considering the application.

Electronic FIR (e-FIR)

Section 173(1) BNSS expressly permits filing of an FIR through electronic communication. The informant must sign the FIR within three days at the police station for it to be valid. Most states offer:

Zero FIR

A Zero FIR is an FIR registered at any police station regardless of territorial jurisdiction. It is numbered "0" temporarily and later transferred to the police station with proper jurisdiction, where it is assigned a regular number.

Origin: Recommended by the Justice Verma Committee after the December 2012 Nirbhaya case; endorsed by MHA advisory of 10 May 2013.

Significance:

Who Can File an FIR?

Anonymous information cannot be FIR — the informant's identity must be recorded.

Contents of an FIR

A properly drafted FIR records:

FieldDescription
Date and time of occurrence of offence
Place of occurrence
Date and time of lodging the FIR
Name and address of the informant
Name of the accused, if known
Particulars of witnesses
Description of the incident — facts only
Provisions of law attracted (sections of BNS, POCSO, NDPS, etc.)
Signature of the informant and SHO

Landmark Judgments

Lalita Kumari v. Government of UP (2014) — 5-judge bench

The Supreme Court held that:

  1. Registration of FIR is mandatory under Section 154 CrPC (now Sec 173 BNSS) if the information discloses a cognizable offence.
  2. No preliminary inquiry is permissible in such situations.
  3. If the information does not disclose a cognizable offence but indicates the need for inquiry, a preliminary inquiry may be conducted within 7 days.
  4. Failure to register an FIR is a dereliction of duty; action must be taken against the officer.

The BNSS has codified a modified version of this ruling — preliminary enquiry is now statutory for 3–7 year offences.

State of Haryana v. Bhajan Lal (1992)

Laid down seven categories where FIR and criminal proceedings can be quashed under Section 482 CrPC (now Sec 528 BNSS) — e.g., allegations do not disclose any offence, allegations are inherently improbable, proceedings are an abuse of process.

Youth Bar Association v. Union of India (2016)

FIRs (except in sensitive categories like sexual offences, POCSO, terrorism) must be uploaded on the police website within 24 hours to enable the accused to obtain copies.

Rights of a Person Filing an FIR

False FIR — Punishment

Filing a false FIR is an offence under:
