The Right of Private Defence of Body and Property

Indian law lets every person defend their own body, another person's body, and property (theirs or someone else's) against certain offences, and anything done in that defence is not an offence. The rules now sit in Sections 34 to 44 of the Bharatiya Nyaya Sanhita, 2023 (BNS), which replaced Sections 96 to 106 of the Indian Penal Code. The right is preventive, it begins with a reasonable fear of danger, and it never allows more harm than is necessary.

This explainer is for B.A. LL.B. and LL.B. students preparing for criminal law papers, and for any citizen who has wondered what they can lawfully do if attacked at home or on the road. Getting this wrong cuts both ways: people either fear using force they are entitled to, or they go well beyond it and face a homicide charge.

What does the BNS actually say?

The provisions form part of the General Exceptions chapter of the BNS. Section 34 is short: "Nothing is an offence which is done in the exercise of the right of private defence." The rest of the scheme builds on that line.

• Section 35 (old IPC 97): you may defend your own or another person's body against any offence affecting the human body, and movable or immovable property against theft, robbery, mischief or criminal trespass, or an attempt at any of these.
• Section 36 (old IPC 98): the right exists even against the act of a person of unsound mind and others who may not be criminally liable, so the attacker's own defence does not take away yours.
• Section 37 (old IPC 99): the limits. There is no right against a public servant acting in good faith under colour of office, unless the act reasonably causes fear of death or grievous hurt, and no right where there is time to seek help from public authorities. Above all, the right never extends to inflicting more harm than necessary.
• Sections 38 and 39 (old IPC 100 and 101): when defence of the body may extend to causing death, and when it extends only to harm short of death.
• Section 40 (old IPC 102): when the right of private defence of the body starts and ends.
• Sections 41, 42 and 43 (old IPC 103, 104 and 105): the same three questions for property.
• Section 44 (old IPC 106): defence against a deadly assault where there is a risk of harming an innocent person.

When can you cause death in defence of the body?

Section 38 lists the assaults that justify causing death, always subject to Section 37. They are an assault that reasonably causes apprehension of death; one that reasonably causes apprehension of grievous hurt; an assault with intent to commit rape; with intent to gratify unnatural lust; with intent to kidnap or abduct; with intent to wrongfully confine a person in circumstances where they may reasonably fear they cannot reach public authorities for release; and throwing or administering acid, or attempting to, in a way that reasonably causes apprehension of grievous hurt.

Outside these cases, Section 39 allows any harm other than death. Picture a student in Nagercoil pushed and slapped in a minor quarrel at a bus stop. He may push back or restrain the other person, but stabbing him would fall well outside the law.

When can you cause death in defence of property?

Section 41 is narrower. Death may be caused only where the offence is robbery; house-breaking between sunset and sunrise; mischief by fire or explosive on a building, tent or vessel used as a dwelling or for keeping property; or theft, mischief or house-trespass in circumstances that reasonably cause fear of death or grievous hurt if the right is not exercised. For anything else, Section 42 permits harm short of death.

Take a tenant in Madurai who finds a neighbour cutting his fence in daylight. That is mischief or trespass with no threat to life. He can stop the person and call the police, but he cannot use lethal force.

When does the right begin and end?

For the body, Section 40 says the right begins as soon as a reasonable apprehension of danger arises from an attempt or threat to commit an offence, even before the offence is committed, and lasts as long as that apprehension lasts. For property, Section 43 sets different end points: for theft, until the offender has retreated with the property, help from public authorities has been obtained, or the property is recovered; for robbery, while the offender causes or attempts death, hurt or wrongful restraint, or the fear of instant harm continues; for criminal trespass or mischief, while the offender continues it; and for night house-breaking, while the house-trespass continues.

The practical point: once the attacker is disarmed, has fled or is lying helpless, the right is over. Anything after that is retaliation.

How has the Supreme Court read these provisions?

1. Deo Narain v. State of U.P. (1973) 1 SCC 347: the right is preventive, not punitive. A person who reasonably fears an attack need not wait to be injured before acting.
2. Darshan Singh v. State of Punjab (2010) 2 SCC 333: the leading modern statement. The Court set out principles still quoted today, including that the right should not be construed narrowly, that a reasonable apprehension is enough, that a person under attack cannot calibrate force precisely, and that force must not be wholly disproportionate. The accused need not prove the plea beyond reasonable doubt.
3. Ratheeshkumar @ Babu v. State of Kerala, 2025 LiveLaw (SC) 74 (decided 9 January 2025): the Court refused the plea where the accused kept stabbing an unarmed man after already wounding him, holding that the action must be strictly preventive, not retributive.
4. Rakesh Dutt Sharma v. State of Uttarakhand, 2025 LiveLaw (SC) 892: a doctor who snatched a pistol from an attacker who had fired at him, and shot him, was acquitted. Relying on Darshan Singh, the Court said the right "cannot be weighed in a golden scale."

What if you go too far, and who has to prove what?

Exceeding the right is not automatically murder. Exception 2 to Section 101 BNS (old IPC 300) reduces murder to culpable homicide where the accused, in good faith exercise of private defence, exceeds the power given by law and causes death without premeditation and without intending more harm than necessary.

On proof, Section 108 of the Bharatiya Sakshya Adhiniyam, 2023 (old Evidence Act 105) places the burden of proving circumstances that bring a case within a general exception on the accused. As Darshan Singh explains, that burden is lighter than the prosecution's: the plea need not be proved beyond reasonable doubt. If you are ever involved in such an incident, report it to the police promptly and get legal advice; free help is available through legal services authorities and clinics such as the college legal aid clinic.

How should you write this answer in an exam?

1. Open with Section 34 and the principle that the right is preventive.
2. State the scope under Section 35 and the limits under Section 37, especially the necessity rule.
3. Apply Sections 38 or 41 to the facts, then Sections 40 or 43 on timing.
4. Cite Deo Narain and Darshan Singh, plus one 2025 case to show the position is current.
5. Close with Exception 2 to Section 101 and the burden under BSA Section 108. Give the old IPC number in brackets once, not throughout.
