1. Introduction: The End of an Era
At the stroke of midnight on 1 July 2024, India bid farewell to one of the world's oldest continuously enforced criminal codes. The Indian Penal Code, 1860 (IPC) — drafted by Lord Macaulay and enacted during British colonial rule — was replaced by the Bharatiya Nyaya Sanhita, 2023 (BNS). This was not merely a statutory update; it was a generational shift in how India defines crime, punishment, and justice.
For over 160 years, the IPC served as the backbone of India's criminal justice system. It survived two world wars, the partition of the subcontinent, independence, and countless constitutional amendments. Yet, by the second decade of the 21st century, it had become increasingly clear that a code drafted in the 1860s — when telegraphs were revolutionary and the British Raj sought primarily to maintain colonial order — was ill-equipped to address cybercrime, organised criminal networks, digital evidence, and evolving societal values.
The Bharatiya Nyaya Sanhita, 2023 was passed by Parliament on 20 and 21 December 2023, received Presidential assent on 25 December 2023, and was brought into force on 1 July 2024. Alongside it, two companion statutes — the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS) replacing the Code of Criminal Procedure, and the Bharatiya Sakshya Adhiniyam, 2023 (BSA) replacing the Indian Evidence Act — completed the most comprehensive overhaul of India's criminal law framework since independence.
The BNS contains 358 sections across 20 chapters, compared to the IPC's 511 sections across 23 chapters. While the reduction appears dramatic, most of it comes from merging related provisions, renumbering, and removing colonial-era debris rather than eliminating substantive offences.
This article provides a detailed, section-by-section comparison of the IPC and BNS, examining what changed, what remained the same, and what practitioners, students, and citizens need to know about navigating India's new criminal law landscape. For readers seeking deeper understanding of specific BNS provisions, we recommend exploring our dedicated analyses such as Section 63 of BNS (Rape), Section 4 of BNS (Types of Punishments), and Section 118 of BNS (Hurt by Dangerous Weapons).
2. Structural Overview: IPC vs BNS at a Glance
Before diving into section-by-section mapping, it is essential to understand the structural philosophy behind the BNS. The IPC was organised around a Victorian conception of criminality — hierarchical, punitive, and designed to protect the colonial state. The BNS, while retaining much of the IPC's substantive content, reorganises offences around contemporary themes and constitutional values.
| Parameter | Indian Penal Code, 1860 | Bharatiya Nyaya Sanhita, 2023 |
|---|---|---|
| Year Enacted | 1860 | 25 December 2023 (Assent) |
| In Force From | 1 January 1862 | 1 July 2024 |
| Total Sections | 511 | 358 |
| Total Chapters | 23 | 20 |
| Drafted By | First Law Commission of British India (Lord Macaulay) | Criminal Law Reform Committee & Ministry of Home Affairs |
| Language | Colonial-era English ("Government of India") | Modernised ("Union Government," "Bharat") |
| Digital Evidence | No specific provision | Integrated with BSA, 2023 |
| Community Service | Not recognised | Formal punishment under Section 4(f) |
Chapter Reorganisation
One of the most significant structural changes in the BNS is the reorganisation of chapters. The IPC scattered offences against women and children across multiple chapters. The BNS consolidates these into a dedicated Chapter V: "Of Offences Against Woman and Child", reflecting a victim-centric approach that prioritises gender justice and child protection. This thematic consolidation makes the code more navigable for practitioners and more intelligible for students preparing for judicial services examinations.
Additionally, the BNS introduces dedicated chapters for organised crime and terrorism — offences that were previously dealt with primarily through special statutes like the UAPA or state-level organised crime laws. By incorporating these into the general penal code, Parliament has signalled that these are no longer exceptional threats but central concerns of India's criminal justice system.
3. Complete Section Mapping: IPC to BNS
For practising advocates, law students, and judicial aspirants, the most immediate challenge posed by the BNS is the comprehensive renumbering of sections. A lawyer who has spent years internalising "Section 302" for murder or "Section 420" for cheating must now recalibrate to "Section 103" and "Section 318" respectively. Below is the definitive mapping chart for the most frequently cited provisions.
| Offence | IPC Section | BNS Section | Status |
|---|---|---|---|
| Murder | 302 | 103 | Renumbered (same elements) |
| Culpable Homicide not amounting to Murder | 304 | 101 | Renumbered |
| Dowry Death | 304B | 80 | Renumbered |
| Attempt to Murder | 307 | 109 | Renumbered |
| Voluntarily Causing Hurt | 323 | 115 | Renumbered |
| Hurt by Dangerous Weapons | 324 | 118(1) | Reformulated (now non-bailable) |
| Grievous Hurt by Dangerous Weapons | 326 | 118(2) | Reformulated (min. 1 year added) |
| Hurt to Extort Property | 327 | 119(1) | Merged & Renumbered |
| Grievous Hurt to Extort Property | 329 | 119(2) | Merged & Renumbered |
| Kidnapping | 363 | 137 | Renumbered |
| Rape | 376 | 64 | Renumbered |
| Cruelty by Husband (498A) | 498A | 85 | Renumbered |
| Cheating | 420 | 318 | Renumbered |
| Criminal Breach of Trust | 406 | 316 | Renumbered |
| Sedition | 124A | 152 | Replaced (new elements) |
| Adultery | 497 | — | Removed |
| Unnatural Offences (consensual) | 377 | — | Removed |
| Attempt to Suicide | 309 | — | Removed |
| Organised Crime | — | 111 | New Offence |
| Terrorism | — | 113 | New Offence |
| Mob Lynching | — | 103(2) | New Offence |
| Snatching | — | 304 | New Offence |
| Sexual Intercourse by Deceitful Means | — | 69 | New Offence |
Critical Mapping Notes
Murder (IPC 302 to BNS 103): The offence elements remain virtually identical. A person causes death with intention or with knowledge that death is the likely consequence, with no general exception applying. The punishment — death or imprisonment for life with fine — is unchanged. However, Section 103(2) BNS introduces a critical new species: murder by a group of five or more persons on grounds of race, caste, community, sex, place of birth, language, or personal belief — the statutory codification of mob lynching. This carries a mandatory minimum of life imprisonment.
Cheating (IPC 420 to BNS 318): The substantive offence of dishonestly inducing delivery of property by deception is preserved. However, practitioners must now read Section 318 together with Sections 338 and 340 BNS (forgery of valuable security and using forged documents) in economic offence cases. The punishment of up to seven years and fine remains identical.
Rape (IPC 376 to BNS 64): The definition from the post-2013 IPC is retained. However, the BNS introduces significant sentencing changes. Rape of a woman under 16 now attracts a mandatory minimum of 20 years under Section 65 BNS. The gang-rape victim age threshold has been raised from 16 to 18 under Section 70(2) BNS. The marital rape exception under Section 63 BNS has been retained, though this remains the subject of pending Supreme Court litigation.
For a detailed breakdown of how Section 119 BNS merges IPC Sections 327 and 329, or how Section 114 BNS redefines "Hurt", refer to our dedicated section-wise guides.
4. What BNS Removed: Offences No Longer Criminal
The BNS has been described as an exercise in "decolonisation" of criminal law. While much of this is rhetorical, there are genuine instances where the new code has discarded provisions that were either colonial relics or had been rendered unconstitutional by the Supreme Court.
Sedition (IPC Section 124A) — Formally Removed
The most celebrated removal is Section 124A IPC — the sedition law that was used to imprison freedom fighters during the independence movement and has been criticised for stifling dissent in modern India. The BNS does not contain a section titled "sedition." However, Section 152 BNS introduces "acts endangering sovereignty, unity and integrity of India," which critics argue covers substantially similar ground. The Rajasthan High Court, in Tejender Pal Singh v. State of Rajasthan (2024), read Section 152 narrowly as a shield for national security rather than a sword against political dissent. A constitutional challenge to Section 152 is currently pending before the Supreme Court.
Adultery (IPC Section 497) — Already Unconstitutional
Adultery was decriminalised by the Supreme Court in Joseph Shine v. Union of India (2018). The BNS wisely does not revive it. This aligns criminal law with constitutional morality and recognises that marital infidelity, while morally reprehensible to many, does not warrant state punishment.
Consensual Same-Sex Relations (IPC Section 377) — Decriminalised
Following Navtej Singh Johar v. Union of India (2018), the consensual portion of Section 377 was read down. The BNS removes this provision entirely. However, non-consensual acts previously covered under Section 377 are now addressed through other provisions of the BNS, though some legal scholars argue there remains a gap in protection for male victims of sexual violence.
Attempt to Commit Suicide (IPC Section 309) — Removed
The BNS omits the offence of attempted suicide, aligning with evolving human rights standards and the Mental Healthcare Act, 2017. This recognises that individuals attempting suicide typically require medical and psychological intervention rather than criminal punishment.
Weights and Measures Offences
Several minor offences related to weights and measures have been moved to the Legal Metrology Act, 2009, decluttering the penal code and placing regulatory offences in their appropriate statutory home.
The removal of these provisions represents a genuine effort to align criminal law with constitutional values. However, practitioners should note that the BNS has not removed the underlying conduct from legal regulation entirely — it has simply relocated it to more appropriate statutes or recognised judicial precedents.
5. New Offences Introduced by BNS
While the BNS retains approximately 80% of the IPC's substantive content, it introduces several genuinely new offence families that reflect contemporary criminal realities. These are not mere rebrandings — they create new categories of criminal liability that did not exist under the IPC.
5.1 Organised Crime (Section 111 BNS)
For the first time, organised crime is defined within India's general penal code. Section 111 BNS defines it as continuing unlawful activity by a syndicate of two or more persons, including kidnapping, robbery, extortion, contract killing, cybercrime, trafficking, and economic offences for material or pecuniary gain. The minimum sentence is five years, extendable to life imprisonment, with death where the offence causes death. The fine is at least Rs. 5 lakh.
This provision intersects with existing state-level organised crime laws (like the Maharashtra Control of Organised Crime Act) and will require careful judicial interpretation to avoid overlapping jurisdiction and double jeopardy concerns.
5.2 Terrorism (Section 113 BNS)
Terrorism is now explicitly defined in the general penal code, though special laws like the UAPA continue to operate. Section 113 BNS covers acts that threaten India's unity, integrity, or public order through violence or coercion. This integration reflects a global trend of mainstreaming counter-terrorism into general criminal law, though concerns about potential misuse and the breadth of definition remain.
5.3 Mob Lynching (Section 103(2) BNS)
The BNS codifies mob lynching as a distinct species of murder. When murder is committed by a group of five or more persons on grounds of race, caste, community, sex, place of birth, language, or personal belief, it attracts the death penalty or life imprisonment, with a mandatory minimum of life imprisonment. This responds to the Supreme Court's 2018 directive in Tehseen S. Poonawalla v. Union of India calling for specific legislation against lynching.
5.4 Snatching (Section 304 BNS)
The IPC did not distinguish between theft and snatching. Section 304 BNS creates a specific offence for snatching — the sudden seizure of property from a person — punishable with imprisonment up to three years and fine. This recognises the distinct modus operandi and heightened victim trauma associated with street snatching.
5.5 Sexual Intercourse by Deceitful Means (Section 69 BNS)
Section 69 BNS is entirely new. It criminalises sexual intercourse obtained by deceitful means, including false promise of marriage, employment, or promotion, where the victim's consent was vitiated by the deception. This addresses a significant gap in Indian criminal law where courts struggled to fit such cases within the narrow definition of rape or cheating. The punishment is up to ten years imprisonment.
Section 69 has no IPC predecessor. Courts interpreting this provision cannot simply import IPC reasoning. The contours of "deceitful means," the mens rea requirement, and the relationship between civil breach of promise and criminal liability will need to be developed through fresh jurisprudence.
5.6 Acts Endangering Sovereignty (Section 152 BNS)
As discussed above, Section 152 replaces the sedition law but introduces new elements including "subversive activities" and armed rebellion. The breadth of this provision has already generated significant litigation, with the Rajasthan High Court cautioning against its use to suppress legitimate dissent.
6. Changes in Punishment & Sentencing
6.1 Community Service: The Sixth Punishment
Perhaps the most symbolically significant addition is community service as the sixth form of punishment under Section 4(f) BNS. Joining death, life imprisonment, simple and rigorous imprisonment, forfeiture of property, and fine, community service represents a shift from purely punitive justice to reformative justice. For a detailed explanation, read our article on Section 4 of BNS — Types of Punishments.
Community service is available for six specific offences including non-appearance in response to a proclamation, defamation, attempt to commit suicide for the purpose of restraint, and certain minor public-order offences. The form — up to 24 hours of unpaid community work supervised by a designated officer — is still being refined through state-level subordinate rules.
6.2 Enhanced Fines
The BNS substantially increases fines for several offences to reflect modern economic realities. For instance:
- Public servant unlawfully engaging in trade: Fine increased from Rs. 1,000 to Rs. 10,000
- Disobedience to public servant's order: Fine increased from Rs. 1,000 to Rs. 5,000-10,000
- Giving false evidence: Fine increased from discretionary to Rs. 5,000-10,000
- Misconduct in public by drunken person: Fine increased from Rs. 10 to Rs. 1,000
- Rash driving: Fine increased from Rs. 1,000 to Rs. 5,000
6.3 Mandatory Minimum Sentences
Several BNS sections introduce or raise mandatory minimum sentences, limiting judicial discretion:
- Rape of woman under 16: Mandatory minimum 20 years (Section 65)
- Gang rape: Mandatory minimum 20 years (Section 70)
- Mob lynching murder: Mandatory minimum life imprisonment (Section 103(2))
- Grievous hurt by dangerous weapons: Minimum 1 year (Section 118(2))
- Trafficking: Mandatory minimum 7-10 years
The dowry death offence under Section 80 BNS retains the same seven-year minimum and life maximum as Section 304B IPC. What changed is the chapter location and section number, not the punishment quantum.
6.4 Default Imprisonment Cap
Under Section 8(3) BNS (formerly Section 65 IPC), imprisonment in default of payment of fine cannot exceed one-fourth of the maximum substantive sentence. Our analysis of the Karnataka High Court ruling on default imprisonment explains how this cap protects liberty in cheque bounce cases under the NI Act.
7. Offences Against Women & Children
The BNS dedicates Chapter V entirely to offences against women and children, consolidating provisions that were previously scattered across the IPC. This thematic consolidation is more than cosmetic — it signals legislative intent to treat gender-based violence as a distinct category requiring specialised attention.
7.1 Sexual Offences Framework
Section 63 BNS defines rape with the same seven circumstances of invalid consent as the post-2013 IPC. The definition includes penetration by penis, insertion of objects, manipulation of body parts, and oral penetration. For a comprehensive breakdown, see our guide on Section 63 of BNS — The Offence of Rape.
The BNS also retains and strengthens provisions for:
- Section 74: Assault or criminal force with intent to outrage modesty (minimum 1 year)
- Section 75: Sexual harassment (rigorous imprisonment up to 3 years)
- Section 76: Assault with intent to disrobe (3-7 years)
- Section 77: Voyeurism (1-3 years)
- Section 78: Stalking (up to 3 years for repeat offence)
7.2 Child Protection
The BNS coordinates with the POCSO Act, 2012 to ensure comprehensive child protection. The age of consent remains 18, and any sexual act with a person below 18 is statutory rape regardless of consent. The BNS also introduces enhanced penalties for offences against children within the general penal code framework.
7.3 Marital Rape Exception
The BNS retains the marital rape exception under Section 63, providing that sexual intercourse by a husband with his wife (above 18 years) is not rape. This exception has been widely criticised and is currently under challenge before the Supreme Court. For related reading on marriage offences, see Offences Relating to Marriage under BNS.
For a complete overview of sexual offences and assault against women and children under the new code, refer to our detailed article on Sexual Offences and Assault Against Woman and Child Under BNS, 2023.
8. Transition Rules: Which Law Applies When?
This is the question that keeps trial court lawyers awake at night. The transition from IPC to BNS is not a clean switch — it is a complex, multi-year process where both codes coexist on court dockets. Understanding which law applies requires navigating constitutional principles, savings clauses, and judicial precedents.
Substantive law follows the date of the offence; procedural law follows the date of the FIR. This is the constitutional floor established by Article 20(1).
8.1 The Constitutional Foundation: Article 20(1)
Article 20(1) of the Constitution of India prohibits ex post facto criminal liability. No person shall be convicted of any offence except for violation of a law in force at the time of the commission of the act, nor subjected to a penalty greater than that which might have been inflicted under the law in force at the time. This means:
- Nobody can be punished under BNS for an act committed before 1 July 2024
- The substantive law applicable is always the law in force when the act was committed
- For pre-July 2024 offences, IPC remains the substantive law regardless of when the FIR is registered
8.2 The Four Transition Scenarios
Both substantive and procedural law are the old codes. IPC governs the offence; CrPC governs the procedure. The BNSS Section 531 savings clause preserves CrPC for proceedings initiated before 1 July 2024. This covers the bulk of pending criminal litigation in India.
The offence occurred before 1 July 2024, but the FIR is registered after. The Allahabad High Court in Deepu v. State of U.P. (2024) held that such FIRs must be registered under IPC sections (substantive) but investigated under BNSS procedure. The Rajasthan High Court in Vijay Sharma v. State of Rajasthan (2024) reinforced this hybrid framework.
Both substantive and procedural law are the new codes. BNS governs the offence; BNSS governs procedure; BSA governs evidence. This is the cleanest scenario and the one that will increasingly dominate as time passes.
For appeals and revisions pending on the cut-off date, CrPC continues to apply under the BNSS Section 531 proviso until final disposal. IPC remains the substantive law.
8.3 Drafting the FIR: A Practical Example
Consider an offence committed on 25 June 2024, with the FIR registered on 8 July 2026. The correct FIR title would read:
Citing "Section 103 BNS" for this offence would be unconstitutional under Article 20(1) and vulnerable to challenge.
9. Does Old IPC Precedent Still Apply Under BNS?
The short answer is: yes, when the offence-element is preserved; no, when it is genuinely new. This distinction is critical for appellate practice, where decades of IPC jurisprudence form the backbone of criminal law doctrine.
9.1 The Continuity Rule
When a BNS provision preserves the same offence-elements as its IPC predecessor, the old precedent applies. Courts should cite the IPC case with a one-line continuity footnote acknowledging the renumbering. This ensures doctrinal stability while acknowledging the statutory transition.
| Landmark Case | IPC Section | Holding | BNS Section | Status |
|---|---|---|---|---|
| Bachan Singh v. State of Punjab (1980) | 302 | "Rarest of rare" doctrine for death penalty | 103 | Good Law |
| Machhi Singh v. State of Punjab (1983) | 302 | Five-criteria test for rarest-of-rare | 103 | Good Law |
| Virsa Singh v. State of Punjab (1958) | 300(3) | "Ordinary course of nature" test | 101 | Good Law |
| Reg. v. Govinda (1876) | 299/300 | Culpable homicide vs. murder line | 100/101 | Good Law |
| K.M. Nanavati v. State of Maharashtra (1962) | 300 Exc. 1 | "Grave and sudden provocation" standard | 101 Exc. 1 | Good Law |
| Joseph Shine v. Union of India (2018) | 497 | Adultery struck down as unconstitutional | — | Good Law (offence removed) |
| Navtej Singh Johar v. Union of India (2018) | 377 | Consensual same-sex relations decriminalised | — | Good Law (offence removed) |
9.2 When Precedent is Displaced
Section 69 BNS (sexual intercourse by deceitful means) has no IPC ancestor. Courts cannot import IPC reasoning uncritically. The mens rea requirement, the scope of "deceitful means," and the boundary between civil breach of promise and criminal liability must be developed through fresh BNS-native jurisprudence.
Similarly, Section 152 BNS, while partially overlapping with the old sedition law, introduces new elements like "subversive activities" that require independent judicial interpretation. The Rajasthan High Court's observation that Section 152 is a "shield for security, not a sword against dissent" provides early guidance, but the Supreme Court's pending constitutional challenge will be definitive.
10. Practitioner Workflow Guide
For lawyers drafting FIRs, charge sheets, bail applications, and appeals after 1 July 2024, the dual-code reality requires meticulous attention to citation. A single wrong section number can invite technical challenges, delay proceedings, and in some cases, violate constitutional protections.
10.1 Drafting the FIR
- Identify the offence date first. This determines the substantive law.
- Identify the FIR registration date. This determines the procedural law.
- For pre-July offences: Cite IPC sections for the offence, BNSS sections for procedure.
- For post-July offences: Cite BNS sections for the offence, BNSS sections for procedure.
- Always include the offence date in the FIR title to clarify which substantive law applies.
10.2 Drafting the Charge Sheet
The charge sheet must mirror the FIR's substantive law citation. For hybrid cases (pre-July offence, post-July FIR), the chargesheet should read: "Charges under IPC Section [X] read with BNSS Section [Y]." Mixing BNS substantive sections with pre-July offences is a constitutional error under Article 20(1).
10.3 Bail Applications
Bail applications must cite the correct procedural code. For proceedings initiated after 1 July 2024, cite BNSS Section 482 (corresponding to CrPC Section 439). For proceedings initiated before 1 July 2024 that continue under the savings clause, cite CrPC sections.
10.4 Citing IPC Precedent in BNS Pleadings
When citing IPC precedent for a BNS offence where the elements are preserved, use this format:
10.5 Common Errors to Avoid
- Citing "IPC 420" on an FIR for a post-July 2024 offence (should be BNS 318)
- Citing "BNS 103" for a murder committed in June 2024 (should be IPC 302)
- Using CrPC citations in proceedings where BNSS applies
- Forgetting to include the offence date in hybrid FIR titles
- Importing IPC precedent uncritically for genuinely new BNS offences like Section 69
11. Post-July 2024 Case Digest
The first two years of BNS jurisprudence have produced several landmark rulings that shape how the new code is being interpreted. These cases provide essential guidance for practitioners navigating uncharted territory.
11.1 Tejender Pal Singh v. State of Rajasthan (2024)
The Rajasthan High Court delivered the first published High Court reading of Section 152 BNS. Justice observed that Section 152 is a shield for national security, not a sword against political dissent. This narrow reading provides early protection against the potential misuse of the sedition replacement.
11.2 Deepu v. State of U.P. (Allahabad HC, 2024)
The foundational ruling on transition law. The Allahabad High Court held that FIRs registered after 1 July 2024 for pre-July offences must be registered under IPC sections (substantive) but investigated under BNSS procedure. This "Deepu hybrid" has become the standard framework for transition cases.
11.3 Vijay Sharma v. State of Rajasthan (2024)
The Rajasthan High Court reinforced the Deepu hybrid framework, providing additional judicial certainty for practitioners handling transition cases.
11.4 Nagani Akram Mohammad Shafi v. Union of India (Bombay HC, 2025)
The Bombay High Court read Section 318 BNS (cheating) together with Sections 338 and 340 BNS (forgery offences) in an economic offence case, establishing the interpretive framework for financial crimes under the new code.
11.5 Rajnish Singh Soni — Section 69 Contours
Early jurisprudence on Section 69 BNS (sexual intercourse by deceitful means) has begun to shape the boundaries of this new offence, distinguishing between genuine breach of promise and criminal deception.
12. Frequently Asked Questions
Conclusion
The transition from the Indian Penal Code to the Bharatiya Nyaya Sanhita represents more than a legislative renumbering exercise. It is a generational shift in how India conceptualises crime, punishment, and justice. While the BNS retains the substantive core of the IPC, it introduces genuinely new offences for the digital age, removes colonial relics, enhances protections for women and children, and adds reformative sentencing options.
For practitioners, the dual-code reality will persist for years. Mastering the transition rules, understanding which precedent applies, and correctly drafting hybrid pleadings are now essential skills. For students and citizens, the BNS offers a more accessible, thematically organised, and constitutionally aligned criminal code — one that, despite legitimate concerns about certain provisions, represents a meaningful step toward a justice system fit for 21st-century India.
