BNS vs IPC: Key Changes in the New Criminal Law

On July 1, 2024, the Indian Penal Code (IPC), 1860 was replaced by the Bharatiya Nyaya Sanhita (BNS), 2023. This is one of the most significant shifts in Indian criminal jurisprudence, and it is now a mandatory part of the KSLU syllabus.

For law students, this means memorizing new section numbers, understanding structural reorganizations, and analyzing brand-new offenses. Here is a breakdown of the key changes you need to know for your upcoming criminal law exams.


1. Structural Reorganization

The BNS reduces the total number of sections to 358, down from the IPC’s 511. This was achieved by merging related sections, removing obsolete provisions, and restructuring the order of chapters.

Crucially, Offenses against the Human Body and Offenses against Women and Children have been brought forward in the code to give them higher priority, reversing the colonial layout of the IPC.


2. Shift in Key Section Numbers

Many of the most famous sections of the IPC have now changed. You must use the new BNS section numbers in your exams to score full marks:

Offense Old IPC Section New BNS Section
Murder Section 302 Section 103
Culpable Homicide Section 299 / 304 Section 100 / 105
Rape Section 375 / 376 Section 63 / 64
Theft Section 378 / 379 Section 303
Cheating Section 415 / 420 Section 318
Defamation Section 499 / 500 Section 356

Note: Murder’s punishment is now in Section 103, while Section 101 defines the offence of murder (formerly Section 300).


3. Key New Offenses Introduced

The BNS introduces several new criminal definitions reflecting modern realities:

  • Organized Crime (Section 111): Covers kidnapping, robbery, land grabbing, contract killing, and cybercrime committed on behalf of a syndicate.
  • Petty Organized Crime (Section 112): Punishes localized syndicate crimes like theft, pickpocketing, card skimming, and shoplifting.
  • Terrorist Act (Section 113): Formally codifies terrorist actions within the general penal law, aligning with special laws like UAPA.
  • Mob Lynching (Section 103(2)): Prescribes the death penalty or life imprisonment for murder committed by a group of five or more people on grounds of race, caste, sex, place of birth, language, or personal belief.
  • Deceitful Sexual Intercourse (Section 69): Criminalizes sexual intercourse accomplished through deceitful means, such as making false promises of marriage or employment.

4. Major Deletions and Modifications

  • Sedition (Section 124A IPC): Has been formally repealed. However, a new provision, Section 152 BNS, criminalizes acts endangering the sovereignty, unity, and integrity of India.
  • Unnatural Offenses (Section 377 IPC): Has been completely omitted from the BNS.
  • Adultery (Section 497 IPC): Which was struck down by the Supreme Court in Joseph Shine, is not included in the BNS.
  • Community Service: Introduced as a new form of punishment for petty offenses (e.g., public misconduct by an intoxicated person, petty theft).

Exam Strategy for KSLU Students

When writing answers on Criminal Law I (BNS), evaluators will expect you to show both the new BNS section numbers and reference their historic IPC equivalents for context.

For instance, when writing an essay on Culpable Homicide vs Murder, start with: "Culpable homicide is defined under Section 100 of the BNS (formerly Section 299 of the IPC) and Murder is defined under Section 101 of the BNS (formerly Section 300 of the IPC)…"

This demonstrates a comprehensive grip on both the historical case law (like Reg. v. Govinda) and the current statutory reality.
