Bharatiya Nyaya Sanhita (BNS) Explained: What Replaced the IPC and How It Affects Your Case

On July 1, 2024, the Indian Penal Code of 1860 ceased to apply to new offences. In its place, the Bharatiya Nyaya Sanhita, 2023 (Act No. 45 of 2023) came into force as India's primary criminal law statute. Alongside it, two companion laws also took effect: the Bharatiya Nagarik Suraksha Sanhita (BNSS) 2023 replacing the Code of Criminal Procedure, 1973, and the Bharatiya Sakshya Adhiniyam (BSA) 2023 replacing the Indian Evidence Act, 1872.

This was the most significant overhaul of Indian criminal law in over 160 years. For anyone with a pending case, a new complaint, or a potential legal dispute in Kerala or anywhere in India, the question is no longer academic: which law applies to your situation?

If the offence was committed before July 1, 2024, the IPC applies. If the offence was committed on or after July 1, 2024, the BNS applies. This is not optional — it is the law under Section 531 of the BNS.

Why the change

The stated rationale for replacing the IPC was to modernise a colonial-era statute, address gaps in existing law, reclassify offences to reflect contemporary values, and introduce new categories of crime that the 1860 code did not contemplate — such as organized crime, terrorism, and mob lynching as distinct statutory offences.

The three new codes were passed by Parliament in December 2023 and came into force on July 1, 2024, after a six-month preparation period for law enforcement, courts, and the legal profession.

The critical section mapping: IPC to BNS

For practitioners, litigants, and anyone trying to understand a charge sheet or complaint, the section number change is the most immediate impact. Here is the mapping for the most frequently encountered offences:

Offence	IPC Section	BNS Section
Murder	302	101
Culpable homicide not amounting to murder	304	105
Death by negligence	304A	106
Attempt to murder	307	109
Rape	376	63–69
Cruelty by husband or relatives	498A	85, 86
Kidnapping	363	137
Robbery	392	309
Criminal breach of trust	406	316
Cheating	420	318
Cheating by personation	419	319
Criminal intimidation	506	351
Forgery	468	336
Defamation	499/500	356
Criminal conspiracy	120B	61
Common intention	34	3(5)
Rioting	147/148	189/190
Hurt and grievous hurt	323/325	115/117
Dowry death	304B	80
Abetment of suicide	306	108

This table covers the sections most commonly encountered in FIRs, charge sheets, and court proceedings across Kerala. If you are reading an old FIR filed under IPC sections, the case continues under the old law. If a new FIR is registered, it will cite BNS sections.

New additions in the BNS

The BNS is not merely a renumbering exercise. Several provisions are genuinely new:

Community service as punishment (Section 4(f))

For the first time in Indian criminal law, community service is recognised as a form of punishment. Courts can now impose community service for minor offences, either as an alternative to imprisonment or in addition to a fine. This is particularly relevant for petty offences where imprisonment is disproportionate.

Organized crime (Section 111)

The BNS introduces a standalone offence for organized crime, defined to include continuing unlawful activity by a syndicate that uses violence, intimidation, coercion, or other unlawful means for direct or indirect economic benefit. The punishment can extend to life imprisonment or death where the organized crime results in death. This provision did not exist in the IPC — organized crime was previously addressed through state-specific laws like the Maharashtra Control of Organised Crime Act.

Terrorism (Section 113)

Terrorism is now a substantive offence under the general criminal law. Section 113 defines terrorist acts and prescribes punishment extending to death or life imprisonment. Previously, terrorism was dealt with exclusively under special statutes like the Unlawful Activities (Prevention) Act (UAPA). The BNS provision operates alongside the UAPA, not as a replacement.

Mob lynching (Section 103(2))

Murder committed by a group of five or more persons on specified grounds (race, caste, community, personal belief, etc.) is now specifically addressed under Section 103(2). The minimum punishment is life imprisonment and fine, with the maximum extending to death.

Snatching (Section 304)

A new offence of snatching is introduced, covering theft by sudden or quick seizure. This was previously charged under general theft provisions and sometimes robbery, depending on the degree of force.

Petty organized crime (Section 112)

A separate provision for petty organized crime covers offences like pickpocket gangs, theft rings, and vehicle-stripping operations carried out in an organized manner. Punishment extends to one to seven years of imprisonment.

What happened to pending cases

This is the question most frequently asked by clients in Kerala who have ongoing criminal matters. The answer is in Section 531 of the BNS:

Offences committed before July 1, 2024 continue to be investigated, inquired into, tried, and otherwise dealt with under the Indian Penal Code, 1860, as if the BNS had not been enacted.

In practice, this means:

• If your case was registered before July 1, 2024, the IPC sections in the charge sheet remain valid
• The trial continues under the old law, with IPC provisions governing conviction and sentencing
• You do not need to get the FIR "converted" to BNS sections
• If you file an appeal in a case decided under the IPC, the appeal is also heard under the old law

The transition provision is clear and does not leave room for ambiguity. However, courts in the initial months after July 1, 2024 did see some confusion in charge sheets that mixed IPC and BNS sections for the same incident. If your charge sheet contains such errors, they should be flagged and corrected.

Implications for NRIs

If you are an NRI with a pending criminal case in India — whether a matrimonial dispute under the erstwhile Section 498A (now BNS Sections 85/86), a cheating case under the old Section 420 (now BNS Section 318), or a property dispute involving criminal intimidation under the old Section 506 (now BNS Section 351) — the governing law depends entirely on when the alleged offence occurred.

For NRIs who need to file new complaints, be aware that:

• FIRs registered in 2025 and 2026 will cite BNS sections, not IPC sections
• Your advocate should reference BNS provisions in all new complaints and legal notices
• Courts in Kochi, Thiruvananthapuram, Thrissur, and Kozhikode are now fully operating under the BNS framework for new cases
• The BNSS (replacing CrPC) governs procedural aspects like bail, arrest, investigation timelines, and chargesheet filing

Companion legislation: BNSS and BSA

The BNS does not operate alone. The full transition includes:

Old law	New law	In force from
Indian Penal Code, 1860	Bharatiya Nyaya Sanhita (BNS), 2023	July 1, 2024
Code of Criminal Procedure, 1973	Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023	July 1, 2024
Indian Evidence Act, 1872	Bharatiya Sakshya Adhiniyam (BSA), 2023	July 1, 2024

The BNSS introduces important procedural changes including mandatory forensic investigation for offences punishable with seven or more years of imprisonment, timelines for filing charge sheets, and provisions for electronic evidence. The BSA updates the law of evidence to formally recognise electronic records, digital signatures, and electronic communication.

Common misconceptions

1. "My IPC case will be dismissed because the IPC is repealed." No. Section 531 preserves all pending cases under the old law.
2. "The BNS is just the same law with new numbers." Partially true for many offences, but the BNS introduces genuinely new offences and modifies penalties for several existing ones.
3. "I can choose whether to file under IPC or BNS." No. The applicable law depends on the date of the offence, not the preference of the complainant.
4. "Old judgments and precedents under the IPC are no longer valid." Incorrect. For offences that have been carried forward with substantially similar ingredients, IPC-era judgments remain persuasive and applicable in BNS cases.

Conclusion

The transition from the IPC to the BNS is the most significant change in Indian criminal law in generations. For anyone involved in a criminal matter — as a complainant, accused, or witness — understanding which law applies and which section number is correct is not a technicality. It determines the charge, the procedure, and the potential outcome.

If you have a pending criminal case, need to file a new complaint under the BNS, or want to understand how the transition affects your rights, book a consultation.
