BNS 2024: New Criminal Law in Kolkata — What Changed from IPC

On 1 July 2024, the criminal justice system of India underwent its most far-reaching transformation in over a century. The Indian Penal Code, 1860 (IPC) was replaced by the Bharatiya Nyaya Sanhita, 2023 (BNS); the Code of Criminal Procedure, 1973 (CrPC) by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS); and the Indian Evidence Act, 1872 by the Bharatiya Sakshya Adhiniyam, 2023 (BSA). For anyone facing a criminal case in the courts of Kolkata — from the magistrate's courts at Bankshall Street to the Calcutta High Court — understanding what changed is essential.

Why the New Criminal Laws Were Introduced

The new codes were enacted with the stated aim of modernising India's criminal justice system, prioritising crimes against women and children, introducing community-oriented policing, and embedding timelines for investigation and trial. The old codes were colonial-era instruments; the new ones reorganise offences, recast procedure and bring in fresh concepts such as organised crime, terrorism, mob lynching and petty organised crime.

For pending cases, the transition is governed by the Bharatiya Nagarik Suraksha Sanhita (Application to Pending Proceedings) provisions — generally, proceedings already commenced under the old law continue under the old law, while new FIRs from 1 July 2024 are registered under the BNS/BNSS/BSA.

Structural Changes You Should Know

• Reorganisation of chapters: Offences against the body are grouped together; offences against women and children are given a dedicated chapter with stiffer penalties.
• Numbering change: Section numbers have changed wholesale. For example, what was section 302 IPC (murder) is now section 103 BNS; section 375 IPC (rape) is now section 64 BNS; section 420 IPC (cheating) is now section 318 BNS. Cross-referencing the old and new sections is a routine task for criminal advocates in Kolkata.
• First Information Report (FIR): The BNSS retains the FIR system but introduces electronic FIR (e-FIR) for certain offences, allowing complaints to be registered online — a feature now being implemented at police stations in Kolkata and the districts.
• Timelines: The BNSS prescribes timelines for medical examination of rape victims (within 24 hours), filing of charge sheet (within 90 days for serious offences, extendable), and judgments to be rendered within a defined period after arguments conclude.

New Offences Introduced by the BNS

The BNS creates several offences that had no direct counterpart in the IPC:

• Organised crime (section 109 BNS): Syndicate-based offences such as contract killing, kidnapping for ransom, extortion, cyber-crime, and money laundering carried out by a group. This is significant for prosecutions in Kolkata relating to organised gangs.
• Terrorist act (section 111 BNS): Codified for the first time in general criminal law, though overlapping with UAPA.
• Mob lynching (section 103(2) BNS): Murder committed by a mob on grounds such as religion, caste, sex, or language, with enhanced punishment.
• Petty organised crime (section 110 BNS): Repeated small offences such as snatching, theft, and cheating carried out by organised groups.
• Snatching (section 302 BNS): Defined as a distinct offence — the sudden, forceful taking of movable property — with up to 3 years imprisonment and fine, addressing a common street crime in Kolkata.
• Sedition replaced: The offence of sedition (section 124A IPC) has been recast as "acts endangering sovereignty, unity and integrity of India" under section 152 BNS.

Key Changes Affecting Cases in Kolkata Courts

Faster Investigation and Charge Sheet

The BNSS emphasises swift investigation. For offences punishable with imprisonment between 3 and 10 years, the police may, with reasons recorded, not arrest if the person cooperates. For serious offences, the charge sheet is to be filed within the prescribed period. This is intended to reduce undertrial detention — a chronic problem in West Bengal's prisons, including the Presidency Central Correctional Home, Alipore.

Summary Trials Expanded

The BNSS expands the scope of summary trials to offences punishable up to 2 years (from the earlier 1-year limit), allowing faster disposal of petty cases in the magistrate's courts in Kolkata. This is particularly relevant for matters under section 303 BNS (theft), section 302 BNS (snatching), and minor assaults.

Forensic and Electronic Evidence

The BNSS mandates forensic investigation for offences punishable with more than 7 years imprisonment, and the BSA codifies the admissibility of electronic records. In Kolkata cases, this means that for serious charges — murder, rape, dacoity — the Forensic Science Laboratory (FSL) report is an expected component of the charge sheet.

Bail and Timelines

The BNSS introduces a presumption of bail for first-time offenders of minor offences and requires the police to issue a "notice of appearance" rather than arrest in certain cases. However, for serious offences, the bail regime remains stringent, and the Calcutta High Court continues to exercise its jurisdiction in serious bail matters.

Specific Offences Against Women — What Changed

• Rape (section 64 BNS): Minimum sentence of 20 years for aggravated rape; life imprisonment for the remainder of natural life; death penalty in the rarest of rare cases.
• Gang rape (section 70 BNS): Minimum 20 years rigorous imprisonment, extendable to life.
• Sexual intercourse by deceitful means (section 69 BNS): A newly framed offence covering sexual intercourse obtained by false promise of marriage, identity, or employment — punishable up to 10 years. This codifies what was earlier developed through case law.
• Voyeurism, stalking, and disrobing: Carried forward and strengthened from the 2013 Criminal Law Amendment.

Practical Implications for Accused and Complainants in West Bengal

• Check the governing law: For offences before 1 July 2024, the IPC/CrPC/Evidence Act apply; for those after, the BNS/BNSS/BSA apply. Confusion here can affect the entire case.
• Section mapping: Ensure the correct BNS section is cited in the FIR, charge sheet, and charge. A wrong citation can be corrected by amendment, but it can also prejudice the accused's defence.
• Timelines as a tool: The prescribed timelines for investigation and trial can be invoked before the magistrate and the High Court to seek relief where the prosecution is dilatory.
• Forensic and digital evidence: Both accused and complainant should be alert to the FSL report, CCTV footage, and electronic evidence, and the right to seek independent expert opinion.
• Bail strategy: The new notice-of-appearance regime and the bail presumption for first-time offenders of minor offences must be considered at the earliest stage of the case.

How the Calcutta High Court Is Interpreting the New Laws

Since July 2024, the Calcutta High Court has been seized of numerous matters under the new codes — bail applications, quashing petitions, and challenges to charges. The Court has consistently emphasised that the procedural timelines in the BNSS are not merely directory but, where violated, give rise to a right to seek relief. The High Court has also clarified that the protections of the old bail jurisprudence continue to inform the new regime, and that the principles governing the grant of bail — gravity, likelihood of tampering, and the accused's antecedents — remain relevant.
