Definition
The right to use force to protect oneself or others from an imminent unlawful attack.
Every person's legal right to defend their body and property against imminent threats — the amount of force used must be no more than reasonably necessary.
Statutory Definition
BNS 2023, Sections 34-44 (formerly IPC Sections 96-106).
Etymology & Origin
From Latin 'privatus' (personal, private) and 'defensa' (a warding off — from 'defendere', to ward off, protect). 'Private defence' is the personal, individual right to defend oneself — as distinguished from the state's right to use force in maintaining public order. The Latin maxim 'vim vi repellere licet' (it is permitted to repel force with force) is the foundational principle.
Full Legal Analysis
Every person has a legally recognised right to defend themselves, their property, and the persons and property of others from unlawful aggression. Sections 34-44 of the BNS, 2023 (formerly Sections 96-106 IPC) codify this right of private defence. The right is both personal (defence of one's own body and property) and altruistic (defence of any other person's body and property). The right exists against any offence affecting the human body (defence of body) or against the offences of theft, robbery, mischief, or criminal trespass (defence of property).
Limits on the right: (1) Proportionality — the harm caused in the exercise of the right must be proportionate to the threat repelled. One cannot use more force than is reasonably necessary to repel the attack; (2) No right against lawful acts — the right of private defence does not arise against lawful acts of police or other public authorities even if those acts seem unjust; (3) Right of recourse to public authorities — if there is time to have recourse to the police or other authorities, the right of private defence does not arise. However, the law does not require the victim to wait until the blow has actually fallen — the right arises when the threat of imminent attack exists.
The Supreme Court set out comprehensive guidelines for applying the right of private defence. The Court held: (1) the right of private defence is a social good — it promotes the protection of individuals who face danger without time to seek state protection; (2) the right does not require the person to wait for actual harm — if the circumstances reasonably lead them to believe that they face imminent danger, they can act; (3) the court should judge the situation from the perspective of the person exercising the right, in the circumstances of the moment of the attack, without the benefit of hindsight; (4) the right extends to causing death only in the six specific circumstances listed in Section 100 IPC (now Section 37 BNS); and (5) if the person who exercises the right causes more harm than necessary, they are liable for the excess.
When the right extends to causing death (Section 37 BNS): the right of private defence can justify causing death only if the assault creates a reasonable apprehension that: (a) death will otherwise result; or (b) grievous hurt will otherwise result; or (c) rape, unnatural lust, kidnapping or abduction, wrongful confinement under circumstances that will deprive them of recourse to public authorities, or throwing acid will otherwise result. This is the 'death situations' — causing death in private defence is justified only to prevent death, grievous hurt, rape, abduction, or acid attack.
For advocates, private defence is a crucial defence in: (1) murder cases — where the accused killed in self-defence; (2) grievous hurt cases — where the injury was caused while defending against an attack; (3) property defence — the limits are narrower; and (4) 'excess of private defence' — where the accused exceeded the right, reducing the charge from murder to culpable homicide not amounting to murder (the excess is punished, but as a lesser offence than murder).

Bharatiya Nyaya Sanhita, 2023, 2023
"Every person has a right, subject to the restrictions contained in section 35, to defend his own body, and the body of any other person, against any offence affecting the human body."
Darshan Singh: no hindsight — judge from moment of attack; right arises before harm falls; Section 37 BNS: death justified only to prevent death, grievous hurt, rape, acid, abduction; excess of private defence reduces murder to culpable homicide
