Bharatiya Nyaya Sanhita

The Bharatiya Nyaya Sanhita, 2023 (BNS) is the new criminal code of India that came into force on 1 July 2024, replacing the Indian Penal Code, 1860 (IPC) — a legislation that had governed criminal law in India for over 160 years since the colonial era. The BNS was enacted as part of a broader overhaul of India's criminal justice system, alongside the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS, replacing the CrPC) and the Bharatiya Sakshya Adhiniyam, 2023 (BSA, replacing the Indian Evidence Act). Together, these three statutes are referred to as the 'three new criminal laws.'

The BNS contains 358 sections, compared to 511 sections in the IPC. While the BNS substantially retains most of the substantive criminal law of the IPC — definitions of offences, mental element requirements, general exceptions, and punishment structures — it makes several significant changes: (1) it introduces organised crime (Section 111 BNS) and terrorism (Section 113 BNS) as expressly defined offences within the code itself, rather than in special legislation; (2) it introduces the offence of 'petty organised crime' (Section 112); (3) it adds a new offence of making someone eat prohibited substances (such as beef or pork) without consent; (4) it restructures some offence categories; and (5) it provides for community service as a form of punishment for minor offences.

The renumbering under the BNS is one of the most practically significant changes for legal practitioners. Section numbers that were memorised under the IPC — 302 (murder), 304A (causing death by negligence), 376 (rape), 420 (cheating) — have all changed under the BNS. For example: murder is now Section 101 BNS (was IPC 302); culpable homicide not amounting to murder is Section 105 BNS (was IPC 304); cheating is Section 318 BNS (was IPC 420); and rape is Section 64 BNS (was IPC 376). This transition requires practitioners to master the new numbering system while also being familiar with the old system for cases that arose before 1 July 2024 and are still governed by the IPC.

Key substantive changes in the BNS include the reordering of offence chapters — offences against the State now appear earlier in the code (reflecting the priority of national security), whereas the IPC had offences against the body and property earlier. The BNS also modifies the definition of 'rape' to include additional categories and clarifies the law on trafficking and sexual offences involving minors. The definition of 'child' in relevant sections is aligned with 18 years (consistent with POCSO and the Juvenile Justice Act), resolving earlier inconsistencies.

For advocates, the transition to the BNS requires careful attention to: (1) which law applies to the specific case — was the offence committed before or after 1 July 2024? (2) What is the new section number for the offence charged? Citing the wrong section number (e.g., citing IPC 302 in a charge for a BNS offence) is a potential defect. (3) Are there new offences or modified mental element requirements that affect the client's case? (4) What is the impact of the new organised crime and terrorism provisions on cases that might previously have been tried under UAPA or MCOCA? These are live questions that will be resolved by judicial interpretation over the coming years.
