Indian Penal Code (IPC): Full Form, Sections, History and BNS Replacement

The Indian Penal Code (IPC) was India’s principal criminal law, defining offences and prescribing punishments until it was replaced by the Bharatiya Nyaya Sanhita (BNS) on 1 July 2024. Its key features include:

• IPC full form: Indian Penal Code.
• Enactment: The IPC was passed on 6 October 1860 and came into force on 1 January 1862.
• Replacement: The BNS replaced the IPC from 1 July 2024, subject to the commencement notification and statutory savings.
• Structure: The IPC contained 23 chapters and 511 sections.
• Important sections: These included provisions on murder, theft, cheating, criminal conspiracy and cruelty by a husband or his relatives.
• Punishments: The IPC provided for death, imprisonment for life, imprisonment, forfeiture of property and fines.
• Current relevance: The IPC continues to matter when determining the applicable substantive criminal law for offences committed before the BNS came into force.

The IPC dealt with offences and punishments. Criminal procedure and rules of evidence were covered by separate laws, which were also replaced in 2024.

The Indian Penal Code, 1860, was a comprehensive law that defined criminal offences and prescribed their punishments in India. It covered offences affecting the human body, property, public order, religion and other areas.

The BNS received the President of India's assent on 25 December 2023 and came into force on 1 July 2024, replacing the IPC as the principal criminal code. The BNS retains many offences from the IPC, revises some provisions and introduces new offences and punishments.

The IPC should not be described as the current general criminal code. However, it remains relevant to cases involving offences committed before 1 July 2024. The applicable law depends on the date of the alleged offence and the relevant statutory savings and transitional provisions.

The IPC was drafted by the First Law Commission of India, established under the Charter Act of 1833 and chaired by Lord Thomas Babington Macaulay. The Commission submitted the first draft in 1837. The code was passed on 6 October 1860 and came into force on 1 January 1862.

After independence, the IPC was amended repeatedly to address changes in criminal law and society. Amendments introduced or revised provisions concerning offences, definitions and punishments. Despite these changes, the code retained much of its original structure until Parliament enacted the BNS.

The following timeline summarises key milestones in the development of the IPC and the introduction of the BNS.

The distinction between the enactment year and the commencement date explains why the law is known as the Indian Penal Code, 1860, even though it came into force in 1862.

The IPC contained 511 sections arranged across 23 chapters. Its provisions covered general principles of criminal liability, punishments, exceptions and specific offences.

This is a selective overview, not a complete chapter-by-chapter index. For the precise wording of an IPC provision, refer to the statutory text and any amendments applicable to the relevant period.

The table below lists commonly referenced IPC provisions and the corresponding BNS provisions that address the same or a related subject. These references are for general orientation; they do not mean that the provisions are identical in wording, scope or punishment.

Important: A section number does not carry over automatically from the IPC to the BNS. For example, murder was addressed by IPC Section 302, while BNS Section 302 concerns a different subject. Always identify the code and check the full provision, including any applicable sub-section.

The IPC's Section 124A on sedition was not carried forward as an identical offence. BNS Section 152 creates an offence addressing specified acts against the sovereignty, unity and integrity of India. The scope and legal requirements of that provision must be assessed from its actual wording rather than treating it as a direct renumbering of Section 124A.

Criminal offences are classified under the applicable criminal procedure law. These classifications affect police powers, arrest, bail and the court before which a case may be tried.

The classification of a particular offence should be checked in the relevant statutory schedule. For an older IPC offence, the date of the alleged conduct and the applicable transitional provisions matter; the classification should not be inferred solely from the BNS section number.

Section 53 of the IPC listed five categories of punishment:

• Death: The punishment prescribed for certain offences, subject to the law and applicable judicial safeguards.
• Imprisonment for life: Imprisonment for life, subject to applicable remission and release laws.
• Imprisonment: Either rigorous imprisonment, involving hard labour, or simple imprisonment, as prescribed.
• Forfeiture of property: Forfeiture where the law specifically provided for it.
• Fine: A monetary penalty imposed under the relevant provision.

The BNS retains several of these categories and adds community service as a form of punishment for specified offences. The punishment applicable to an offence depends on the precise provision, the circumstances of the case and the law governing the alleged conduct.

For more than 160 years, the IPC provided a common statutory framework for defining criminal offences and their punishments. Its main contributions included:

• Defining offences: It described prohibited conduct and the legal consequences associated with it.
• Supporting consistent application of criminal law: Its provisions supplied a common framework across much of India, subject to amendments and special laws.
• Establishing general principles: It set out provisions on criminal liability, abetment, common intention, general exceptions and attempts.
• Providing a basis for criminal cases: Police, advocates and courts referred to its sections when investigating, prosecuting and deciding cases governed by the IPC.
• Supporting the development of case law: Judicial decisions interpreted its provisions and shaped their application over time.

The BNS now serves as the principal criminal code for offences within its scope committed from its commencement, while the IPC remains relevant to earlier offences under the applicable savings provisions.

The IPC was criticised for retaining elements of its colonial origins and for provisions that did not fully reflect later constitutional and social developments. These criticisms were not uniform across every provision, and several sections were amended or interpreted by courts over time.

Common areas of criticism included:

• Colonial origins: The code was drafted during British rule and retained provisions shaped by that historical context.
• Sedition: Section 124A was criticised for its potential effect on political expression. Its operation was also affected by Supreme Court proceedings before the BNS came into force.
• Gender and sexuality: Some provisions were criticised for reflecting unequal treatment or outdated assumptions. The Supreme Court had already decriminalised consensual same-sex relations between adults to the extent Section 377 was read down, and struck down the offence of adultery under Section 497 before the BNS was enacted.
• Interpretation and enforcement: The application of some provisions, including those concerning group liability and public order, generated debate about the balance between effective enforcement and individual rights.
• Changing forms of crime: Developments in technology and organised criminal activity increased calls to review the structure and scope of criminal law.

The BNS changed the statutory framework, but the effect of each change must be assessed provision by provision. Replacing the IPC did not remove the need for constitutional scrutiny, judicial interpretation or amendments to criminal law.

The IPC shaped everyday life by defining conduct that could lead to criminal liability and prescribing punishments for offences against the person, property and public order. It was relevant to cases involving theft, assault, cheating, murder, criminal intimidation and other offences.

Since 1 July 2024, the BNS has served as the principal criminal code for offences within its scope committed from that date. The IPC remains relevant to earlier offences under the applicable legal provisions. The law applicable to a particular case depends on the facts, the date of the alleged conduct and the relevant transition rules.

The IPC did not itself establish all rights relating to property, free speech or criminal procedure. Those matters are governed by the Constitution and other applicable laws, including separate legislation on criminal procedure and evidence.

The IPC and the Constitution serve different legal purposes. The IPC defined criminal offences and punishments, while the Constitution establishes India's governing framework and protects constitutional rights.

The Constitution can also affect the interpretation and validity of criminal laws. A statutory provision must operate consistently with applicable constitutional requirements.

The BNS replaced the IPC as India's principal criminal code from 1 July 2024. It retains many offences, changes some provisions and introduces additional offences and community service as a punishment.

Some changes commonly associated with the new criminal laws belong to the Bharatiya Nagarik Suraksha Sanhita (BNSS), which replaced the Code of Criminal Procedure (CrPC), or the Bharatiya Sakshya Adhiniyam (BSA), which replaced the Indian Evidence Act. Those changes should not be attributed to the BNS unless they are contained in the BNS itself.

Three new criminal laws came into force from 1 July 2024 to replace three earlier central laws. Each addresses a different part of the criminal justice system.

The substantive criminal law, procedure and rules of evidence must be considered separately. Which law applies to an individual case depends on the dates and circumstances involved, as well as the savings and transitional provisions in the new laws.

The BNS retains many IPC offences but changes the wording, scope or punishment of some provisions and introduces new offences. Some offences that had already been struck down or read down by the courts were not retained in the same form.

The table gives a high-level summary. It does not replace an examination of the statutory text, judicial decisions or any other legislation that may apply to the same conduct.
