Filing an FIR and the Investigation Process under BNSS, 2023: A Step-by-Step Guide

Filing an FIR and the Investigation Process under BNSS, 2023: A Step-by-Step Guide

The Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, which replaces the Criminal Procedure Code (CrPC), aims to make the Indian criminal justice system faster, fairer, and more transparent. One of the most significant aspects of criminal law is the First Information Report (FIR) and the subsequent investigation process.

In this blog, we will explain in simple language how FIRs are filed under BNSS, how investigations proceed, the rights of the accused and the victim, and how the new law improves upon the old system.


๐Ÿ“ 1. What is an FIR?

An FIR (First Information Report) is the first step in a criminal case. It is a document prepared by the police when they receive information about the commission of a cognizable offence.

A cognizable offence means a serious crime (like murder, rape, kidnapping, etc.) where the police can arrest without permission from the court.


๐Ÿ“œ 2. Relevant BNSS Provisions for FIR and Investigation

The following sections of the BNSS deal with FIR and investigation:

  • Section 173 – Information in cognizable cases (FIR)

  • Section 174 – Information in non-cognizable cases

  • Section 175 – Procedure when police do not register FIR

  • Section 176 – Preliminary inquiry

  • Section 179 – Investigation process

  • Section 193 – Powers of police during investigation

  • Section 193-198 – Police powers to arrest, examine, search

  • Section 210 – Completion of investigation and charge sheet


๐Ÿ›‘ 3. Filing an FIR (Section 173 BNSS)
