Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. The January 2026 paper asked candidates to “critically examine the rationale behind the BNS replacing the IPC” and to list its key reforms. A good answer has three parts: where the IPC came from, what the BNS actually changed (with section numbers), and a balanced view of how much is new and how much is renumbering.

1. Historical background: Macaulay and the IPC

The Charter Act of 1833 set up the first Law Commission under Lord Macaulay. Its draft penal code was submitted in 1837, revised over the following years, and enacted after the events of 1857 as the Indian Penal Code, 1860 (Act 45 of 1860), in force from 1 January 1862. It drew on English criminal law, the French Code Pénal and Livingston's Louisiana Code, and was admired for its precise definitions and its use of illustrations.

The IPC was amended many times: dowry death (s.304B) and cruelty (s.498A) in the 1980s, the Criminal Law (Amendment) Act, 2013 after the Delhi gang rape, and the 2018 amendment on rape of children. Courts also cut it down, striking out or reading down s.377 and s.497 and suspending the operation of sedition (s.124A). The case for a fresh code rested on these accumulated changes and on the colonial origin and vocabulary of the old one.

2. Enactment and commencement

The Bharatiya Nyaya Sanhita, 2023 (Act 45 of 2023) received the President's assent on 25 December 2023, together with the Bharatiya Nagarik Suraksha Sanhita (replacing the CrPC) and the Bharatiya Sakshya Adhiniyam (replacing the Evidence Act). Under s.1(2) the Central Government appointed 1 July 2024 as the date of commencement, except for s.106(2) (hit and run), which was held back. Section 358 repeals the IPC but saves anything done, any liability incurred and any proceeding pending under it; offences committed before 1 July 2024 are still tried under the IPC.

The Sanhita has 358 sections in 20 chapters, against 511 sections in the IPC. Much of the reduction comes from consolidation (for example, s.2 gathers the IPC's scattered definitions, and the general provisions on punishment of fine are grouped in s.8).

3. Extent and operation: section 1

4. Definitions and general explanations: sections 2 and 3

Section 2 defines thirty-nine terms in alphabetical order: “child” means a person below eighteen (s.2(3)); “document” includes electronic and digital records (s.2(8)); “good faith” requires due care and attention (s.2(11)); “movable property”, “public servant” (s.2(28)), “dishonestly” and “fraudulently” follow the IPC. Section 3 holds the general explanations: every offence is subject to the General Exceptions (s.3(1)); acts include illegal omissions (s.3(4)); and joint liability for common intention (s.3(5), old s.34 IPC).

Gender neutrality. By s.2(10), “he” and its derivatives are used of any person, “whether male, female or transgender”, with transgender carrying its meaning under the Transgender Persons (Protection of Rights) Act, 2019. Several offences against children, such as procuration (s.96), are now gender-neutral. But rape (s.63) remains an offence by a man against a woman.

5. Key reforms over the IPC

6. The rationale, critically examined

The Government's stated aims were to remove colonial vocabulary and priorities, to place offences against the human body, women and children ahead of offences against the State, and to deal with modern crime (organised crime, terrorism, cyber offences). These are real changes.

The criticism is that most of the Code is the IPC renumbered: the general exceptions, abetment, homicide, hurt and property offences are reproduced almost word for word. Renumbering imposes costs on courts and lawyers for limited gain. Specific concerns raised by commentators include the width of s.152, the overlap of s.113 with the UAPA, the omission of any offence of non-consensual sexual acts against adult men after s.377 was dropped, and the retention of the marital rape exception (Exception 2 to s.63). A balanced answer accepts the modernising reforms and notes that the real test will be how courts read the new provisions.

Trap. Do not write that sedition was struck down. The Supreme Court upheld s.124A, read down, in Kedar Nath Singh v. State of Bihar, 1962 INSC 17, AIR 1962 SC 955. In 2022, in S.G. Vombatkere v. Union of India, it directed by interim order that s.124A be kept in abeyance. The BNS then dropped the section and enacted s.152.

How this is examined

As an essay: “Critically examine the rationale behind the BNS replacing the IPC and its key reforms” (January 2026), or “Explain the historical background and salient features of the BNS.” As a short note: extra-territorial operation, community service, or s.152. List the reforms with section numbers and, where useful, the old IPC section in brackets. End the essay with your own assessment; the word “critically” is asking for one.
