Right of Private Defence Under The Bharatiya Nyaya Sanhita, 2023
India's criminal justice system underwent a massive transformation on 1st July 2024 when the Bharatiya Nyaya Sanhita, 2023 (BNS) officially replaced the colonial-era Indian Penal Code, 1860 (IPC). Among the many provisions carried forward and refined in this new code, the Right of Private Defence stands out as one of the most fundamental and practical rights available to every citizen. This right is not merely a legal technicality — it is a recognition of the most basic human instinct: the instinct to protect oneself, one's loved ones, and one's property from unlawful aggression.
In this comprehensive guide, we will explore every aspect of the Right of Private Defence under the BNS 2023 — from its foundational principles in Section 34 to its limitations in Section 37, from when it extends to causing death in Section 38 to when it applies to property in Section 41. Whether you are a law student preparing for exams, a legal professional, or a common citizen who wants to understand your rights, this article will serve as your complete resource.
๐ Chapter III: The Home of Private Defence in BNS
The Right of Private Defence is housed in Chapter III (General Exceptions) of the Bharatiya Nyaya Sanhita, 2023. This chapter contains provisions that excuse or justify acts that would otherwise be criminal offences. The right of private defence is not a licence to commit violence — it is a carefully balanced legal exception that allows a person to use reasonable force to protect themselves or others from imminent danger.
The provisions on private defence in the BNS span from Section 34 to Section 44. These sections collectively form a complete code on when, how, and to what extent a person can lawfully defend themselves. The old IPC provisions (Sections 96 to 106) have been restructured and renumbered, but the core philosophy remains intact — with some important modernizations and clarifications.
๐ฏ Quick Overview of BNS Private Defence Provisions:
• Section 34: General principle — acts done in private defence are not offences
• Section 35: Scope — defence of body and property
• Section 36: Defence against acts of unsound mind, minors, or intoxicated persons
• Section 37: Limitations — when private defence is NOT available
• Section 38: When body defence extends to causing death
• Section 39: When body defence extends only to harm (not death)
• Section 40: Commencement and continuance of right to defend body
• Section 41: When property defence extends to causing death
• Section 42: When property defence extends only to harm (not death)
• Section 43: Commencement and continuance of right to defend property
• Section 44: Risk of harm to innocent persons during defence
⚖️ Section 34 BNS — The Foundation: Nothing is an Offence Done in Private Defence
Section 34 of the Bharatiya Nyaya Sanhita is the cornerstone of the entire private defence framework. It states a simple but powerful principle: "Nothing is an offence which is done in the exercise of the right of private defence."
This section corresponds to Section 96 of the old IPC, and the language is almost identical. The message is crystal clear — when a person uses necessary and proportionate force to defend themselves against unlawful aggression, the law does not treat that act as a crime. It is a justifiable act, not a punishable offence.
The philosophy behind Section 34 is deeply rooted in natural justice. The law recognizes that when danger strikes, a person cannot always wait for the police or public authorities to arrive. In those critical moments, the right to self-preservation must be respected. However, this right is not unlimited — it is subject to the restrictions laid down in the subsequent sections, particularly Section 37.
Section 34 covers three broad categories of defence:
- ✓ Defence of one's own body: Protecting yourself from assault, attack, or any offence affecting the human body.
- ✓ Defence of another person's body: Coming to the rescue of a family member, friend, or even a stranger who is under unlawful attack.
- ✓ Defence of property: Protecting your movable or immovable property from theft, robbery, mischief, or criminal trespass.
The burden of proving that an act falls within the exception of private defence lies on the accused. Under Section 108 of the Bharatiya Sakshya Adhiniyam, 2023 (the new Evidence Act), the accused must establish that their case comes within this general exception.
๐ก️ Section 35 BNS — The Scope: Defence of Body and Property
Section 35 defines the exact scope of the right of private defence. It corresponds to Section 97 of the IPC and states:
"Every person has a right, subject to the restrictions contained in section 37, to defend —
(a) his own body, and the body of any other person, against any offence affecting the human body;
(b) the property, whether movable or immovable, of himself or of any other person, against any act which is an offence falling under the definition of theft, robbery, mischief or criminal trespass, or which is an attempt to commit theft, robbery, mischief or criminal trespass."
This section is remarkable for its breadth. It protects not just your own body and property, but also the body and property of any other person. This means you can lawfully intervene to save a stranger from being attacked or to prevent someone's house from being burglarized. The law encourages civic courage — the willingness to stand up against unlawful acts even when you are not personally affected.
Defence of Body (Section 35(a))
The right to defend the body applies against "any offence affecting the human body." This is a wide expression that covers:
- ✓ Assault and criminal force (Sections 115-122 BNS)
- ✓ Voluntarily causing hurt (Section 115 BNS)
- ✓ Voluntarily causing grievous hurt (Section 117 BNS)
- ✓ Wrongful restraint and wrongful confinement (Sections 126-127 BNS)
- ✓ Kidnapping and abduction (Sections 137-140 BNS)
- ✓ Rape and sexual assault (Section 63 BNS)
- ✓ Attempt to murder (Section 101 BNS)
- ✓ Culpable homicide (Section 100 BNS)
The key requirement is that there must be an "offence affecting the human body." Mere verbal abuse or insult does not trigger this right, because such acts do not amount to offences against the body under criminal law.
Defence of Property (Section 35(b))
The right to defend property is more specific. It applies only against four categories of offences:
- ✓ Theft: Dishonest removal of movable property (Section 303 BNS)
- ✓ Robbery: Theft with force, fear, or violence (Section 309 BNS)
- ✓ Mischief: Causing wrongful loss or damage to property (Section 324 BNS)
- ✓ Criminal Trespass: Unlawful entry into property (Section 329 BNS)
Importantly, the right also extends to attempts to commit these offences. So if someone is trying to break into your house but has not yet succeeded, you still have the right to use reasonable force to stop them. The law recognizes that prevention is better than cure — waiting until the offence is complete may be too late.
The property protected can be movable (like a car, jewellery, or phone) or immovable (like land, house, or building). It can belong to you or to any other person. This means you can lawfully defend your neighbour's house from arson or prevent a stranger's bag from being snatched.
๐ง Section 36 BNS — Defence Against Acts of Unsound Mind, Minors, and Intoxicated Persons
Section 36 of the BNS deals with a tricky but important question: What if the person attacking you is not legally responsible for their actions? This could be:
- ✓ A child who is too young to understand the nature of their act
- ✓ A person of unsound mind who cannot distinguish right from wrong
- ✓ A person acting under intoxication who lacks control over their actions
- ✓ A person acting under a misconception about the situation
Section 36 states that even in these situations, the victim has the same right of private defence as they would have if the attacker were a fully responsible adult. The law focuses on the threat posed, not the mental state of the attacker.
This is a crucial provision. Imagine a scenario where a person with schizophrenia attacks you with a knife. Even though that person may not be guilty of any offence due to their mental condition, you still have the right to defend yourself. You cannot be expected to pause and assess the attacker's mental health before protecting your own life.
The section corresponds to Section 98 of the IPC and maintains the same principle: the right of private defence is based on the nature of the act, not the culpability of the actor.
๐ซ Section 37 BNS — The Limitations: When Private Defence is NOT Available
Every right has its limits, and the right of private defence is no exception. Section 37 imposes critical restrictions to prevent the misuse of this right. It corresponds to Section 99 of the IPC and is the most important section for understanding the boundaries of self-defence.
Section 37 states that there is no right of private defence in the following situations:
1. Against Public Servants Acting in Good Faith
There is no right of private defence against an act done by a public servant (like a police officer) acting in good faith under the colour of their office, provided the act does not reasonably cause apprehension of death or grievous hurt.
This means you cannot resist a lawful arrest by claiming self-defence. If a police officer is performing their duty lawfully, you must comply. However, if the officer's act is so violent that it creates a reasonable fear of death or grievous hurt, then the right of private defence may still apply.
Explanation 1 to Section 37 adds an important safeguard: a person is not deprived of the right of private defence against a public servant's act unless they know or have reason to believe that the person is a public servant. If a plain-clothed officer fails to identify themselves, the victim may not lose their right of defence.
Explanation 2 further clarifies that if a person acts under the direction of a public servant, the victim must know or have reason to believe that such direction exists. If the person claims authority, they must produce written proof if demanded.
2. When There is Time to Seek Public Authority Help
There is no right of private defence in cases where there is sufficient time to have recourse to the protection of public authorities. This means if you can reasonably call the police or seek help from authorities, you should do so instead of taking the law into your own hands.
The rationale is simple: private defence is an emergency measure, not a substitute for the state's law enforcement machinery. When the state is available to protect you, you should rely on it.
3. Proportionality: No Excessive Force
The most fundamental limitation is that the right of private defence in no case extends to inflicting more harm than is necessary for the purpose of defence. This is the doctrine of proportionality — the force used must match the threat faced.
You cannot shoot someone who merely slapped you. You cannot burn down a thief's house because they stole your wallet. The response must be reasonable and necessary under the circumstances.
Courts recognize that a person under attack cannot weigh their response in "golden scales" — they must act in the heat of the moment. However, the force must still be proportionate to the danger. Using a gun against an unarmed person who poses no threat to life would generally be considered excessive.
๐ Section 38 BNS — When Body Defence Extends to Causing Death
This is one of the most serious aspects of private defence law. Section 38 specifies seven situations where the right to defend the body extends to voluntarily causing the death of the assailant. These are grave offences where the threat to life is so severe that lethal force becomes justifiable.
The seven situations are:
- ✓ (a) An assault that may reasonably cause the apprehension that death will otherwise be the consequence of such assault.
- ✓ (b) An assault that may reasonably cause the apprehension that grievous hurt will otherwise be the consequence of such assault.
- ✓ (c) An assault with the intention of committing rape.
- ✓ (d) An assault with the intention of gratifying unnatural lust.
- ✓ (e) An assault with the intention of kidnapping or abducting.
- ✓ (f) An assault with the intention of wrongfully confining a person, under circumstances which may reasonably cause them to apprehend that they will be unable to have recourse to public authorities for their release.
- ✓ (g) An act of throwing or administering acid, or an attempt to throw or administer acid, which may reasonably cause the apprehension that grievous hurt will otherwise be the consequence of such act.
These seven categories reflect the law's understanding of the most serious threats to human life and dignity. When faced with any of these assaults, a person may use lethal force to defend themselves — subject always to the restrictions in Section 37.
It is important to note that the test is "reasonable apprehension." The defender does not need to prove that death or grievous hurt was certain — only that a reasonable person in their position would have feared such consequences. The law judges the situation from the perspective of the person under attack, not with the benefit of hindsight.
The addition of acid attack (clause g) in the BNS is a significant modernization. Acid attacks have become a horrific form of violence in India, particularly against women. Recognizing that a person facing an acid attack may use lethal force to defend themselves is a welcome step that aligns the law with contemporary realities.
๐ค Section 39 BNS — When Body Defence Extends Only to Harm (Not Death)
Section 39 deals with situations where the offence against the body does not fall under the seven grave categories listed in Section 38. In such cases, the right of private defence does not extend to causing death, but it does extend to causing any harm other than death.
For example, if someone attempts to slap you or push you (which does not amount to assault causing apprehension of death or grievous hurt), you cannot kill them in self-defence. But you can push them back, restrain them, or cause minor injuries to stop the attack.
This section ensures a graded response — the severity of defensive force must match the severity of the threat. Lethal force is reserved only for the most dangerous situations.
⏱️ Section 40 BNS — Commencement and Continuance of Right to Defend Body
Section 40 answers two critical questions: When does the right begin? and When does it end?
The right of private defence of the body commences as soon as a reasonable apprehension of danger to the body arises from an attempt or threat to commit the offence — even if the offence has not actually been committed yet. This means you do not have to wait until you are actually hit or stabbed. If someone raises a knife against you and you reasonably fear an attack, your right of defence has already begun.
The right continues as long as such apprehension of danger continues. Once the danger is over — the attacker has fled, been subdued, or stopped their attack — the right ends. You cannot chase down a fleeing attacker and beat them up, claiming self-defence.
This "preventive" nature of the right is crucial. It allows people to act before the harm occurs, not just after. Waiting for the actual blow might be too late.
๐ Section 41 BNS — When Property Defence Extends to Causing Death
Section 41 specifies when the right to defend property extends to causing death. This is more restrictive than body defence, because the law values human life above property. However, in certain extreme situations, lethal force to protect property is justified.
The four situations are:
- ✓ (a) Robbery: When someone uses force or threat of force to steal your property.
- ✓ (b) House-breaking after sunset and before sunrise: Night-time burglary of a dwelling. The BNS modernizes the old IPC language of "house-breaking by night" to the more precise "after sunset and before sunrise."
- ✓ (c) Mischief by fire or any explosive substance: When someone sets fire to or uses explosives on a building, tent, or vessel used as a human dwelling or for custody of property. This includes arson attacks on homes.
- ✓ (d) Theft, mischief, or house-trespass: Under circumstances that may reasonably cause apprehension that death or grievous hurt will be the consequence if the right of private defence is not exercised. This is a catch-all provision for situations where property crimes escalate into threats to life.
The rationale for allowing lethal force in these property situations is that they often involve an implicit threat to human life. A robber is not just stealing — they are using violence. A night-time burglar in your home poses a direct threat to your family's safety. Arson can kill sleeping occupants. In these contexts, protecting property and protecting life become inseparable.
๐จ Section 42 BNS — When Property Defence Extends Only to Harm (Not Death)
For property offences that do not fall under the four grave categories of Section 41, the right of private defence does not extend to causing death. However, it does extend to causing any harm other than death.
For example, if someone is committing simple theft (without robbery) during the daytime, you cannot kill them. But you can tackle them, restrain them, or cause non-lethal injuries to stop the theft and recover your property.
Again, the principle of proportionality governs. The force must be necessary and reasonable for the protection of property.
⏰ Section 43 BNS — Commencement and Continuance of Right to Defend Property
Section 43 mirrors Section 40 but applies to property. The right of private defence of property commences when a reasonable apprehension of danger to the property arises. It continues as long as such apprehension continues.
For property, the right typically continues until:
- ✓ The offender has retreated or left the premises
- ✓ The stolen property has been recovered
- ✓ The threat to the property has ceased
Once the danger to property is over, the right ends. You cannot hunt down a thief days later and claim you were defending your property.
๐ถ Section 44 BNS — Risk of Harm to Innocent Persons
Section 44 addresses a difficult moral and legal question: What if, while defending yourself against an attacker, you accidentally harm an innocent bystander?
The section states that the right of private defence extends to the voluntary causing of harm to another person (even an innocent person) if:
- ✓ There is a sudden and extreme emergency
- ✓ The harm to the innocent person is unavoidable in the exercise of the right of private defence
- ✓ There is no safe alternative available
This is a limited and carefully circumscribed exception. It does not give a blank cheque to harm bystanders. It applies only in genuine emergencies where the defender had no reasonable way to avoid collateral harm.
For example, if someone is shooting at you in a crowded market and you fire back in self-defence, accidentally hitting a bystander, you may be protected under Section 44 — provided the circumstances were truly unavoidable and there was no safe alternative.
๐ BNS vs IPC: A Comparative Overview
The transition from IPC to BNS has renumbered the private defence provisions but preserved their substance. Here is the mapping:
BNS 2023 ↔ IPC 1860 Mapping:
• Section 34 BNS ↔ Section 96 IPC — General Principle
• Section 35 BNS ↔ Section 97 IPC — Scope: Body & Property
• Section 36 BNS ↔ Section 98 IPC — Unsound Mind, Minors
• Section 37 BNS ↔ Section 99 IPC — Limitations
• Section 38 BNS ↔ Section 100 IPC — Body Defence to Death
• Section 39 BNS ↔ Section 101 IPC — Body Defence to Harm Only
• Section 40 BNS ↔ Section 102 IPC — Commencement: Body
• Section 41 BNS ↔ Section 103 IPC — Property Defence to Death
• Section 42 BNS ↔ Section 104 IPC — Property Defence to Harm Only
• Section 43 BNS ↔ Section 105 IPC — Commencement: Property
• Section 44 BNS ↔ Section 106 IPC — Risk to Innocent Persons
The BNS has made some important modernizations:
- ✓ Acid attack added: Section 38(g) now explicitly includes acid attacks as a situation where lethal force is justified.
- ✓ "House-breaking by night" updated: Section 41(b) now uses the more precise "after sunset and before sunrise" instead of the vague "by night."
- ✓ "Unnatural lust" clarified: Section 38(d) replaces the archaic IPC language with modern terminology.
- ✓ Cleaner structure: The BNS organizes the provisions more logically, making them easier to understand and apply.
⚖️ Landmark Case Laws on Private Defence
Indian courts have interpreted the right of private defence through numerous landmark judgments. These cases provide practical guidance on how the law works in real-life situations:
๐ Munshi Ram v. Delhi Administration (AIR 1968 SC 702)
The Supreme Court recognized that the right of private defence of property extends to protecting it against unlawful aggression, including trespass and mischief. The court emphasized that this right is a preventive, not punitive, measure.
๐ Yogendra Moraji Thakkar v. State of Gujarat (AIR 1980 SC 660)
The Supreme Court held that the right of private defence is available only when there is a reasonable apprehension of danger. The court must judge the situation from the perspective of the accused at the time of the incident, not with hindsight.
๐ State of U.P. v. Ram Swarup (AIR 1974 SC 1570)
The Supreme Court clarified that the right of private defence is not a right to punish the offender. It is a right to protect oneself or one's property. Once the danger is over, any further use of force becomes unlawful.
๐ Jai Dev v. State of Punjab (AIR 1963 SC 612)
The Supreme Court held that the burden of proving that the accused acted in private defence lies on the accused, but the burden is not as heavy as that of the prosecution. The accused only needs to raise a reasonable doubt about their guilt.
๐ Puran Singh v. State of Punjab (AIR 1975 SC 498)
The Supreme Court emphasized that the right of private defence must be exercised with restraint. Excessive force beyond what is necessary for defence loses the protection of the law.
๐ฏ Practical Examples: Understanding Private Defence in Real Life
Let us look at some everyday scenarios to understand how these provisions work:
Scenario 1: Home Invasion at Night
A burglar breaks into your house after midnight. You hear the noise, grab a cricket bat, and confront him. He attacks you with a knife. You strike him with the bat, causing serious injury. This is lawful private defence under Section 38 (apprehension of death) and Section 41 (house-breaking after sunset).
Scenario 2: Street Robbery
Someone snatches your phone and pushes you. You chase them, catch them, and retrieve your phone after a scuffle. This is lawful under Section 35 (defence of property against theft). However, if you beat them severely after recovering the phone, that would be excessive force and lose protection.
Scenario 3: Acid Attack
A person throws acid at a woman on the street. A bystander tackles the attacker, causing injury. This is lawful private defence under Section 38(g) — defence against acid attack. The bystander can also claim defence of another person's body under Section 35(a).
Scenario 4: Resisting Arrest
A police officer in uniform tries to arrest you lawfully. You resist, claiming self-defence. This is NOT lawful under Section 37(a) — there is no right of private defence against a public servant acting in good faith, unless the act causes apprehension of death or grievous hurt.
Scenario 5: Chasing a Fleeing Thief
A thief steals your wallet and runs away. You chase him for two kilometres, catch him, and beat him badly. The initial chase to recover property may be lawful, but the beating after catching him is not protected — the right ended when the immediate threat to property ceased.
๐ Key Takeaways for Law Students and Citizens
- ✓ Private defence is a right, not a privilege: Every person has this right by virtue of being a human being.
- ✓ It is preventive, not punitive: The purpose is to stop harm, not to punish the wrongdoer.
- ✓ Proportionality is key: The force used must match the threat. Excessive force loses protection.
- ✓ Reasonable apprehension matters: The law judges from the perspective of a reasonable person in the same situation.
- ✓ Time limits apply: The right begins when danger is apprehended and ends when danger ceases.
- ✓ Public servants are protected: You cannot use private defence against lawful state action.
- ✓ Property defence is narrower: Lethal force for property is allowed only in extreme situations like robbery, night burglary, and arson.
- ✓ Acid attacks now covered: The BNS explicitly includes acid attacks as a situation justifying lethal force.
- ✓ Burden of proof on accused: The accused must prove their case falls within private defence.

⚖️ Conclusion: The Right That Protects Every Citizen
The Right of Private Defence under the Bharatiya Nyaya Sanhita, 2023 is one of the most important protections available to every Indian citizen. It recognizes that when danger strikes, people must be able to protect themselves without fear of criminal prosecution. At the same time, it imposes sensible limits — proportionality, necessity, and reasonableness — to prevent this right from becoming a tool for violence or revenge.
The BNS has modernized these provisions by adding acid attacks to the list of grave threats, clarifying night-time burglary with precise timing, and maintaining the core philosophy that self-preservation is a natural right. Whether you are defending your body, your property, or another person, the law stands with you — as long as you act within reason.
"The right of private defence is a right of protection, not a right of aggression. It is the shield of the innocent, not the sword of the violent."
