Right of Private Defence is the legal right of every person to defend their own body or property, or the body or property of another person, against an offence, using reasonable force including, in specified circumstances, force extending to the causing of death. Under Indian law, this right is codified in Sections 96-106 of the Indian Penal Code, 1860 (now Sections 34-44 of the Bharatiya Nyaya Sanhita, 2023).
Legal definition
Section 96 IPC (Section 34 BNS) establishes the foundational principle:
Nothing is an offence which is done in the exercise of the right of private defence.
Section 97 IPC (Section 35 BNS) defines the scope of this right:
Every person has a right, subject to the restrictions contained in Section 99, to defend — (First) his own body, and the body of any other person, against any offence affecting the human body; (Secondly) 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.
When the right extends to causing death — Section 100 IPC (Section 38 BNS) enumerates six situations where private defence of the body extends to causing the death of the assailant:
- An assault that reasonably causes the apprehension of death
- An assault that reasonably causes the apprehension of grievous hurt
- An assault with the intention of committing rape
- An assault with the intention of gratifying unnatural lust
- An assault with the intention of kidnapping or abduction
- An assault with the intention of wrongful confinement where the person cannot have recourse to the public authorities
Section 104 IPC (Section 42 BNS) similarly extends the right of private defence of property to causing death in cases involving robbery, house-breaking by night, mischief by fire to a dwelling house, or theft/mischief/house-trespass likely to cause death or grievous hurt.
Restrictions — Section 99 IPC (Section 37 BNS) limits the right: it does not extend to causing more harm than is necessary, nor is it available against acts done by public servants acting in good faith under colour of their office.
How courts have interpreted this term
Vidhya Singh v. State of Madhya Pradesh [(1971) 3 SCC 244]
The Supreme Court established that the right of private defence is a defensive right, not a retaliatory one. The Court held that "the right of private defence is essentially a defensive right available only when the circumstances clearly justify it." There must be a reasonable apprehension of danger and the force used must be commensurate with the threat perceived.
Ex-CT Mahadev v. Director General, BSF [(2022) — Supreme Court]
The Supreme Court held that a person taking a plea of self-defence need not prove it beyond reasonable doubt. The accused must only show, on a preponderance of probability, that the circumstances existed which gave rise to the right of private defence. The Court emphasised that the situation must be judged "from the subjective point of view of the accused concerned in the surrounding excitement and confusion of the moment."
Darshan Singh v. State of Punjab [(2010) 2 SCC 333]
The Supreme Court clarified that the right of private defence commences as soon as a reasonable apprehension arises and continues as long as the apprehension persists. The right does not require the accused to wait for the first blow. However, once the apprehension ceases — for example, when the assailant retreats or is incapacitated — the right ceases, and further harm constitutes an offence.
Why this matters
The right of private defence is one of the most frequently invoked defences in criminal trials involving violence. It provides legal protection to individuals who use force — including lethal force — to protect themselves, their families, or their property from criminal aggression. Without this right, any retaliatory or defensive act against an assailant would itself constitute an offence.
For defence practitioners, successfully establishing private defence can result in acquittal even in cases of murder or culpable homicide. The critical elements are: (a) establishing that the accused faced a genuine and imminent threat, (b) demonstrating that the force used was proportionate to the threat, and (c) proving that the accused did not exceed the boundaries of the right. Courts assess proportionality contextually — they do not expect mathematical precision from a person acting in the heat of the moment.
A common misunderstanding is that private defence justifies pre-emptive violence or retaliation after the threat has passed. It does not. The right is strictly tied to the existence and continuance of an apprehension of danger. Chasing a fleeing assailant and causing harm is not private defence — it is retaliation, which attracts criminal liability.

Frequently asked questions
Can the right of private defence extend to causing death?
Yes. Under Section 100 IPC (Section 38 BNS), the right extends to causing death in six enumerated situations: apprehension of death, grievous hurt, rape, unnatural lust, kidnapping or abduction, and wrongful confinement preventing access to public authorities. Similarly, Section 104 IPC (Section 42 BNS) allows causing death in defence of property in cases of robbery, night house-breaking, and mischief by fire.
Does the accused need to prove private defence beyond reasonable doubt?
No. The accused need only establish the defence on a preponderance of probability. The Supreme Court has held that the accused must raise sufficient evidence to create a reasonable doubt about whether the act was done in self-defence. The prosecution then bears the burden of disproving the defence beyond reasonable doubt.
Can private defence be exercised against a police officer?
The right does not generally extend to acts done by public servants acting in good faith under Section 99 IPC (Section 37 BNS). However, if the public servant acts without jurisdiction, without reasonable cause, or in a manner that causes reasonable apprehension of death or grievous hurt, the right of private defence may be available.
