# BNS, BNSS and BSA Explained for CLAT 2027: India's New Criminal Laws
On 1 July 2024, India replaced its three foundational criminal laws — laws that had governed the country since the British colonial era — with a new framework built around three statutes. The Bharatiya Nyaya Sanhita (BNS) replaced the Indian Penal Code (IPC) of 1860. The Bharatiya Nagarik Suraksha Sanhita (BNSS) replaced the Code of Criminal Procedure (CrPC) of 1973. The Bharatiya Sakshya Adhiniyam (BSA) replaced the Indian Evidence Act of 1872.
For CLAT aspirants, this is not just current affairs — it is legal reasoning territory. The Consortium of NLUs has already used passage-based questions drawing on the new criminal law framework in CLAT 2026. CLAT 2027 will almost certainly do the same. More importantly, a large proportion of legal reasoning passages in CLAT are built around criminal law principles: what constitutes an offence, how intent connects to liability, what the punishment is, and whether a given fact scenario crosses a legal threshold. If you are still thinking in terms of IPC section numbers, you are preparing for an exam that no longer exists.
This post covers the three new laws, what they change from the old framework, and — most importantly — how they show up in CLAT passages.

The three laws at a glance
Before going into the details, it helps to understand what each law does and what it replaced.
Bharatiya Nyaya Sanhita (BNS), 2023 defines criminal offences and their punishments. It is the substantive criminal law — what constitutes murder, theft, fraud, rape, terrorism, and so on. It replaces the Indian Penal Code, 1860. The BNS has 358 sections across 20 chapters, compared to the IPC's 511 sections across 23 chapters. The reduction reflects consolidation of overlapping provisions and removal of obsolete ones, not a narrowing of the law's scope.
Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023 governs criminal procedure — how crimes are investigated, how trials are conducted, how bail is granted, how judgments are pronounced. It replaces the Code of Criminal Procedure, 1973 (CrPC). The BNSS introduces specific timelines for investigations and judgments that the old CrPC did not mandate.
Bharatiya Sakshya Adhiniyam (BSA), 2023 governs evidence law — what can be admitted in court, how documents are proved, what standard of proof applies. It replaces the Indian Evidence Act, 1872. The BSA significantly expands the admissibility of electronic evidence.
All three came into force together on 1 July 2024. Cases registered before that date continue under the old laws (IPC, CrPC, Evidence Act). Cases registered on or after 1 July 2024 are governed by the new framework.
The three laws are designed as an integrated system. Understanding BNS in isolation — as a replacement for IPC — misses the picture. The procedural reforms in BNSS and the evidence reforms in BSA are what make the substantive changes in BNS enforceable.
What the BNS changes from the IPC — and what it keeps
Approximately 80% of BNS provisions are direct replicas or minor rewordings of IPC provisions. The core structure of criminal liability — actus reus (the guilty act), mens rea (the guilty mind), and punishment — is unchanged. What matters for CLAT is the 20% that is genuinely different.
1. Sedition removed; sovereignty offence introduced
Section 124A of the IPC criminalised sedition — the act of exciting or attempting to excite disaffection towards the government. It was a colonial-era provision used extensively by the British to prosecute freedom fighters, and it remained in use long after Independence. In 2022, the Supreme Court put Section 124A on hold pending a constitutional review.
The BNS removes the word "sedition" and deletes the provision entirely. However, Section 152 of the BNS introduces a new offence: acts endangering the sovereignty, unity and integrity of India. This covers exciting or attempting to excite secession, armed rebellion, or subversive activities; encouraging separatist feelings; or endangering India's sovereignty. The punishment is imprisonment up to life, or seven years, with fine.
The critical distinction: the old sedition law could potentially be applied to mere expression of disapproval of government policy. Section 152 of BNS, on its face, requires something more — an act that endangers sovereignty or encourages actual separatism. However, terms like "subversive activities" remain undefined, and critics argue the new provision may be as broadly applicable as the old one.
For CLAT: A passage presenting a situation where someone is charged under Section 152 BNS for speech critical of government policy is exactly the kind of scenario CLAT setters build legal reasoning questions around. The principle to apply: does the speech amount to incitement to secession or separatism, or is it merely critical expression? The boundary between the two is the legal reasoning challenge.
2. Organised crime and terrorism — new central-law offences
Two major additions to the BNS have no direct equivalent in the IPC. Organised crime (Section 111) and terrorist acts (Section 113) are now explicitly defined offences under central criminal law for the first time.
Previously, organised crime was handled under state-specific laws — the Maharashtra Control of Organised Crime Act (MCOCA), the Gujarat Control of Terrorism and Organised Crime Act (GCOCA), and similar statutes. There was no national definition. Section 111 of BNS defines organised crime as unlawful activity — including kidnapping, extortion, cybercrime, human trafficking, drug trafficking, and contract killing — committed by a member of, or on behalf of, a crime syndicate. The definition requires that more than one chargesheet has been filed before a competent court in the preceding ten years.
Terrorism (Section 113) is defined as an act intending to threaten the unity, integrity, security or economic security of India, or to intimidate the general public, or to disturb public order. This includes the use of explosives, lethal weapons, hazardous substances, or cyberattacks. Punishment ranges from five years to life imprisonment without parole, or death.
Petty organised crime (Section 112) is a separate, lower-threshold offence: theft, snatching, cheating, unauthorised sale of tickets, illegal betting, or selling public examination question papers, when committed as a member of a group or gang. Punishment: up to three years imprisonment.
For CLAT: Organisation, coordination, and group intent are the legal issues these sections raise. A passage about a group that runs a coordinated pickpocketing ring, for instance, is now potentially a petty organised crime passage — not just a theft passage. The principle changes: individual liability merges with group liability, and the standard for establishing membership in a "syndicate" or "gang" becomes the legal threshold the question tests.
3. Mob lynching — a new specific offence
Section 103(2) of the BNS introduces mob lynching as a distinct criminal offence. Murder committed by a group of five or more persons on grounds of race, caste or community, sex, place of birth, language, personal belief, or any other similar ground is punishable with a minimum of seven years imprisonment, extendable to life imprisonment or death.
This is significant because the IPC had no specific mob lynching provision. Such cases were prosecuted as ordinary murder under Section 302 IPC, or as unlawful assembly under Section 141 IPC. The BNS treats the identity-based collective motivation of mob violence as a distinct aggravating feature warranting a separate provision.
For CLAT: The element of five or more persons acting on identity-based grounds is the legal threshold. A passage might present a scenario where fewer than five persons were involved, or where the motivation was personal (a business dispute, for example, not an identity ground) and ask whether Section 103(2) applies. These are precision-application questions — exactly what CLAT legal reasoning tests.
4. Community service — a new form of punishment
The BNS introduces community service as a punishment for certain minor offences for the first time in Indian criminal law. This is not imprisonment; it is court-ordered unpaid work that benefits the community.
Offences for which community service may be prescribed include: a public servant engaging in illegal trade, attempt to commit suicide to coerce a public authority, public intoxication and misconduct, defamation, and petty theft by a first-time offender where the stolen property worth less than five thousand rupees was restored.
For CLAT: Community service passages test whether a student can identify when the restorative punishment option is available versus when imprisonment is mandatory. A passage about a first-time theft case, for instance, might present the community service option and ask whether it applies given the facts — raising questions about the threshold conditions.
5. Sexual offences — key changes
The BNS retains the IPC's core provisions on rape, voyeurism, stalking, and outraging the modesty of a woman. However, several changes are significant for CLAT.
The age threshold for classification as a minor in gang rape cases has been raised from 16 to 18 years. Under the IPC, gang rape on a girl below 16 had a higher mandatory minimum than gang rape on women above 16. BNS removes this differential — gang rape of any woman below 18 is now punishable with imprisonment for the remainder of natural life, or death.
A new offence has been added: sexual intercourse by deceitful means or false promises. A man who has sexual intercourse with a woman by deceiving her (for instance, by making false promises of marriage or employment) commits an offence.
The BNS retains the marital rape exception — sexual intercourse by a man with his own wife is not rape under the new law, as it was not under the IPC. This remains a contested area of law.
For CLAT: The 18-year threshold change, the new deceit-based offence, and the retained marital rape exception are all testable in passages. Know the thresholds precisely: a fact scenario involving a 17-year-old victim of gang rape and a 17-year-old victim who is not a minor under the old law but is under the new law — these require you to know which law applies to when.
6. Hit-and-run — stricter punishment for fleeing drivers
Section 106(2) of the BNS creates a specific offence for a person who causes death by rash and negligent driving and then flees without reporting the incident to police or a magistrate. Punishment: imprisonment up to ten years and fine.
Under the old IPC Section 304A, causing death by negligence carried a maximum of two years. The BNS dramatically raises the stakes for drivers who abandon accident victims.
For CLAT: The duty to report is the key legal element. A passage about a driver who stays at the scene and assists the victim would not attract Section 106(2) — the offence requires flight. A passage about a driver who flees would. The distinction is the legal threshold the question tests.
7. Transgender persons — recognised as a gender
Section 2(10) of the BNS defines "gender" to include male, female, and transgender persons. The IPC recognised only male and female. This brings the criminal law definition into alignment with the Transgender Persons (Protection of Rights) Act, 2019 and the Supreme Court's recognition of transgender identity in NALSA v. Union of India (2014).

What the BNSS changes from the CrPC — the key procedural reforms
CLAT passages about criminal procedure will increasingly draw on BNSS language. Three reforms are the most examination-relevant.
Zero FIR and e-FIR formalised. A Zero FIR can now be filed at any police station regardless of jurisdiction — the station that receives the complaint registers it and transfers it to the jurisdictionally appropriate station. Electronic FIRs (e-FIRs) for certain offences can be filed online. Both were informal practices before; BNSS gives them statutory recognition.
Mandatory videography of search and seizure. The BNSS requires that search and seizure operations be video-recorded. This addresses a longstanding criticism that evidence can be planted during searches. Video recording creates a contemporaneous record that is admissible in court.
Defined timelines for investigation and judgment. The BNSS mandates that investigations of rape and POCSO cases be completed within two months. Judgments must be pronounced within 30 days of the conclusion of arguments, extendable to 45 days. These timelines address the notorious backlog in Indian criminal courts.
Extended police remand. For specific offences, the BNSS permits police custody to be extended up to 60 days (from the CrPC's default of 15 days), with judicial magistrate oversight. Critics argue this increases the risk of custodial abuse.
First-time offender bail. A first-time offender who has served one-third of the maximum sentence for the offence is entitled to bail, regardless of the nature of the crime. This is a significant liberalisation intended to reduce prison overcrowding.

What the BSA changes from the Indian Evidence Act — electronic evidence
The most significant change in the BSA relative to the old Evidence Act is the substantial expansion of electronic evidence. The BSA makes electronic records — emails, text messages, WhatsApp chats, digital documents, and cloud-stored data — admissible as primary evidence. Under the old Evidence Act, electronic records were admissible but required a Section 65B certificate (an attestation from the owner of the computer that produced the record), which was cumbersome and frequently challenged.
The BSA streamlines this process and treats electronic records on a closer footing with physical documents. This has significant implications for cybercrime cases, fraud trials, and any case in which digital communication is central evidence.
How the new laws appear in CLAT passages — what to expect
CLAT passages built around the new criminal law framework will almost always do one of three things.
The first is a threshold test: given a fact scenario, does the conduct cross the legal threshold defined in a BNS section? The passage will give you the section (or a paraphrase of it), and the questions will ask whether the facts satisfy every element. Section 103(2) mob lynching requires five or more persons and an identity-based ground. Section 111 organised crime requires a syndicate and prior chargesheets. Section 152 requires an act that endangers sovereignty, not mere dissent.
The second is a comparison with the old law: a passage might describe a fact scenario that would have been handled differently under IPC and ask which outcome follows under BNS. The sedition removal, the raised gang rape threshold, and the new deceit-based sexual offence are the most likely sources of this type of question.
The third is a procedure or evidence principle: particularly from BNSS and BSA. Does a Zero FIR need to be filed at the nearest station? What is required to make an electronic record admissible? When is a first-time offender entitled to bail? These are procedural principles that CLAT can test in the same passage-based format as substantive criminal law.
The single most common error aspirants make with the new criminal laws is conflating BNS with IPC section numbers. CLAT passages will use BNS section numbers. Know the key BNS sections — not because you will be asked to recall them cold, but because recognising them in a passage tells you which legal framework applies.
The ten BNS sections CLAT aspirants must know
These are the sections most likely to appear in CLAT 2027 passages, either by number or by the principle they encode.
Section 103(2) — Mob lynching: murder by five or more persons on identity grounds. Minimum seven years, maximum life or death.
Section 106(2) — Hit-and-run with flight: causing death by rash driving and failing to report. Up to ten years.
Section 111 — Organised crime: unlawful activity by a crime syndicate member. Requires prior chargesheets.
Section 112 — Petty organised crime: theft, snatching, cheating by a group. Up to three years.
Section 113 — Terrorism: acts threatening India's unity, security or public order. Five years to death.
Section 152 — Acts endangering sovereignty, unity and integrity of India (replaces Section 124A IPC sedition). Up to life imprisonment.
Section 63–99 — Sexual offences including rape, stalking, voyeurism, and the new deceit-based sexual intercourse offence.
Section 2(10) — Gender includes transgender persons.
Section 317 — Consolidated stolen property provisions (consolidates IPC Sections 410–414).
Section 4 — Community service as punishment (the enabling provision for courts to award this new penalty type).

Frequently asked questions
Has the IPC been completely replaced? Yes. The IPC, CrPC, and Indian Evidence Act were all repealed with effect from 1 July 2024. Cases registered before that date continue under the old laws. All new cases are under BNS, BNSS, and BSA.
Do I need to memorise BNS section numbers for CLAT UG? Not all of them — CLAT UG does not test rote recall of section numbers. However, knowing the key sections (listed above) helps you recognise legal principles instantly when you see them in a passage, which saves time. For CLAT PG, section-number familiarity is more directly tested.
Is sedition still an offence in India? The word "sedition" and Section 124A IPC have been removed. A new offence under Section 152 BNS criminalises "acts endangering the sovereignty, unity and integrity of India." Critics argue this is sedition in substance, regardless of the label.
Does BNS address marital rape? No. The marital rape exception — which excludes a husband's non-consensual sexual intercourse with his wife from the definition of rape — has been retained in BNS as it was in IPC. This remains a pending constitutional question before the courts.
What is the difference between organised crime (Section 111) and petty organised crime (Section 112)? Organised crime requires activity by a crime syndicate (a structured group with a continuing purpose) and prior chargesheets filed against members. Petty organised crime is simply any of a list of minor offences — snatching, ticket touting, cheating, selling exam papers — committed by any group or gang, without the syndicate threshold.
Why does CLAT 2027 care about procedural law (BNSS) when legal reasoning focuses on principles? Because CLAT passages are drawn from real legal developments, and BNSS reforms — mandatory videography, timeline-based investigations, e-FIR, first-offender bail — have generated extensive journalistic and legal commentary. A passage about police accountability in investigations, or about prison overcrowding, or about the rights of an accused during investigation, is built on BNSS principles. The "principle" in a legal reasoning passage can come from procedural law as easily as from substantive law.
