The right of private defence is the most elaborate of the General Exceptions. It recognises that where the State cannot protect a person in time, that person may protect himself and others, and may even cause death to the aggressor in certain specified situations. The right is defensive, not retaliatory: it exists to prevent harm, not to punish wrongdoing.
BNS S.34 to S.44 correspond to IPC S.96 to S.106. The substance is virtually identical. BNS S.38 = IPC S.100 (when right extends to causing death, body). BNS S.41 = IPC S.103 (when right extends to causing death, property). BNS S.37 = IPC S.99 (restrictions). BNS S.38(g) (acid attack) is new and has no IPC equivalent.
Framework
| Provision | Content |
|---|---|
| S.34 | Nothing done in private defence is an offence |
| S.35 | The right extends to defence of one's own body and property, and the body and property of any other person |
| S.36 | The right exists even against persons of unsound mind, minors, or those acting under misconception |
| S.37 | Restrictions: no right (a) against a public servant acting in good faith where there is no reasonable apprehension of death or grievous hurt; (b) where there is time to have recourse to public authorities; (c) the harm inflicted must not exceed what is necessary |
| S.38 | When right of private defence of body extends to causing death (seven situations) |
| S.39 | When right extends to any harm other than death (all other cases) |
| S.40 | Commencement and continuance of the right (body) |
| S.41 | When right of private defence of property extends to causing death (four situations) |
| S.42 | When right extends to any harm other than death (property) |
| S.43 | Commencement and continuance of the right (property) |
| S.44 | Right against deadly assault where there is risk of harm to an innocent person |
The Three Restrictions (S.37)
| Restriction | Content |
|---|---|
| (1)(a) | No right against an act of a public servant acting in good faith under colour of office, unless it causes reasonable apprehension of death or grievous hurt |
| (1)(b) | No right against an act done by direction of a public servant in good faith, with the same proviso |
| (1)(c) | No right where there is time to have recourse to the protection of the public authorities |
| (2) | The right in no case extends to inflicting more harm than is necessary for the purpose of defence |
Why proportionality is the governing principle: Private defence is a concession by the State, not a licence to kill. The State retains the monopoly on punishment. The defender may use only the force reasonably necessary to repel the attack, and must stop when the danger ends.
When the Right Extends to Causing Death (Body): S.38
The right extends to causing death only if the offence is of one of these descriptions:
| S.38 Clause | Offence Occasioning the Right |
|---|---|
| (a) | Assault reasonably causing apprehension of death |
| (b) | Assault reasonably causing apprehension of grievous hurt |
| (c) | Assault with intent to commit rape |
| (d) | Assault with intent to gratify unnatural lust |
| (e) | Assault with intent to kidnap or abduct |
| (f) | Assault with intent to wrongfully confine, under circumstances causing reasonable apprehension of inability to reach public authorities |
| (g) | Throwing or administering acid, or attempt, reasonably causing apprehension of grievous hurt |
S.38(g) is new in the BNS. The IPC had no specific clause for acid attacks; the BNS added it in response to the prevalence of acid violence.
When the Right Extends to Causing Death (Property): S.41
| S.41 Clause | Offence Occasioning the Right |
|---|---|
| (a) | Robbery |
| (b) | House-breaking after sunset and before sunrise |
| (c) | Mischief by fire or explosive to a building used as a dwelling or for custody of property |
| (d) | Theft, mischief or house-trespass under circumstances reasonably causing apprehension of death or grievous hurt if the right is not exercised |
Commencement and Continuance (S.40, S.43)
Body (S.40)
- Commences: as soon as a reasonable apprehension of danger arises from an attempt or threat, though the offence may not yet have been committed.
- Continues: as long as such apprehension continues.
Property (S.43)
| Offence | When Right Commences and Continues |
|---|---|
| Generally | When reasonable apprehension of danger to property commences |
| Theft | Until the thief has retreated with the property, or public assistance is obtained, or the property is recovered |
| Robbery | As long as the offender causes or attempts death, hurt or wrongful restraint, or as long as fear of instant death, hurt or restraint continues |
| Criminal trespass or mischief | As long as the offender continues in the commission |
| House-breaking after sunset and before sunrise | As long as the trespass begun by such breaking continues |
Key Judicial Principles
Facts: The accused, attacked by a group, killed one of the assailants.
Issue: Whether the right of private defence was available and whether it was exceeded.
Held: The right is available even if the defender could have retreated. There is no duty to retreat. However, the force used must be proportionate to the threat. The accused was entitled to the right but was held to have exceeded it.
Relevance: Establishes that there is no duty to retreat in Indian law, but proportionality governs.
Facts: A detailed examination of when the right of private defence is available in cases of sudden attack.
Held: The Court laid down principles: (1) the right is available from the moment of reasonable apprehension, not only after the first blow; (2) it is a right of defence, not of retribution; (3) the court must consider the position of the defender at the time, not with the advantage of hindsight; (4) the defender is not expected to weigh harm with precision in the heat of the moment.
Relevance: The modern restatement of the principles. Cite for the "heat of the moment" concession on proportionality.
Facts: The accused killed the deceased with a knife during a sudden encounter.
Held: Private defence is not available to a person who is the aggressor. The right presupposes that the defender is the victim of an offence, not the initiator.
Relevance: The defence fails where the accused was the aggressor. This is a common trap.

Distinctions
| Basis | Right to Cause Death (S.38/S.41) | Right to Cause Any Harm Other Than Death (S.39/S.42) |
|---|---|---|
| When | Only if the offence is of the descriptions in S.38 or S.41 | All other cases |
| Proportionality | Death is the maximum permissible response | Any harm short of death |
| Example (body) | Assault causing apprehension of death: may kill | Simple assault: may restrain, push, strike, but not kill |
| Example (property) | Robbery: may kill | Simple theft: may restrain, recover property, but not kill |
| Basis | Private Defence (S.34 to S.44) | Exception 2 to S.101 (Murder) |
|---|---|---|
| Scope | Complete defence; acquittal | Partial defence; reduces murder to culpable homicide |
| When | Defender exercises right within limits | Defender exceeds the right without premeditation |
| Outcome | Not guilty | Guilty of culpable homicide not amounting to murder |
| Requirement | Proportionate force | Exceeding without premeditation and without intention of doing more harm than necessary |
| Basis | Body (S.38 to S.40) | Property (S.41 to S.43) |
|---|---|---|
| What is defended | Life, limb, modesty | Movable and immovable property |
| Death situations | Seven (including acid, new in BNS) | Four |
| Duration | As long as apprehension of danger to body continues | Depends on the nature of the offence (see S.43 table above) |
| Night-time relevance | Not specifically tied to night | House-breaking after sunset and before sunrise is a death situation (S.41(b)) |
Flashcards
State the principle in S.34.
Nothing done in the exercise of the right of private defence is an offence.
Against whom does the right extend under S.36?
Against acts of persons of unsound mind, minors, intoxicated persons, or those acting under misconception. The defender has the same right as if the attacker were a sane adult.
What is the new clause in S.38 that the IPC did not have?
S.38(g): acid attack or attempt to throw or administer acid causing reasonable apprehension of grievous hurt.
Is there a duty to retreat?
No. Vidhya Singh v State of MP (1971) holds there is no duty to retreat in Indian law.
Can the aggressor claim private defence?
No. James Martin v State of Kerala (2004): the right presupposes the defender is the victim, not the initiator.
What happens if the defender exceeds the right?
If death is caused without premeditation while exercising the right in good faith, Exception 2 to S.101 reduces the offence from murder to culpable homicide not amounting to murder.
Exam Scenario
Problem: At 2 a.m., Naresh hears breaking sounds from his ground-floor window. He grabs a hockey stick and confronts two men who have broken open the window and entered his house. One intruder lunges at Naresh with a screwdriver. Naresh strikes him on the head with the hockey stick, killing him. The other intruder flees. Naresh chases him into the lane and strikes him from behind, fracturing his skull. Advise Naresh on the first and the second blow.
Step 1: Classify the offence occasioning the right (first intruder)
The offence is house-breaking after sunset and before sunrise (it is 2 a.m.). Under S.41(b), this is one of the four situations in which the right of private defence of property extends to causing death.
Additionally, the intruder lunged at Naresh with a screwdriver. This constitutes an assault causing reasonable apprehension of grievous hurt (a screwdriver can puncture, stab). Under S.38(b), the right of private defence of the body also extends to causing death.
Both S.38(b) and S.41(b) are satisfied. Naresh was entitled to cause death to the first intruder.
Step 2: Test the first blow for proportionality
| Factor | Assessment |
|---|---|
| Was there time to have recourse to authorities? | No, 2 a.m., intruder already inside |
| Was the force proportionate? | A hockey stick against a lunging intruder with a screwdriver is proportionate |
| Was Naresh the aggressor? | No, he was the defender |
The first blow is fully justified. Naresh is acquitted.
Step 3: Test the second blow (the fleeing intruder)
The second intruder fled. The question is whether the right of private defence continued after the flight.
Under S.43(b): the right against theft continues until the thief has retreated or assistance is obtained or property is recovered. Under S.43(e): the right against house-breaking after sunset continues as long as the trespass continues.
Once the intruder has fled the house, the house-trespass has ended. The property danger has ceased. The apprehension of danger to Naresh's body has also ended, since the intruder is running away.
The right of private defence had terminated before the second blow.
Step 4: Classify the second blow
Naresh chased the intruder and struck him from behind. This is not defence; it is retaliation. Apply James Martin v State of Kerala (2004): once the danger ends, the right ceases.
Naresh is liable for the injury caused to the second intruder. Depending on the outcome (fractured skull = grievous hurt), he may be charged under BNS S.117 (voluntarily causing grievous hurt).
Night-time house-breaking is a death situation. Do not stop at S.38 (body). S.41(b) independently justifies causing death for house-breaking after sunset and before sunrise.
The right ceases when the danger ceases. Flight ends the trespass and removes the apprehension. Pursuit after flight is retaliation, not defence.
No duty to retreat does not mean a right to pursue. Vidhya Singh says the defender need not retreat. That is different from authorising pursuit of a fleeing person.
Conclusion. Naresh is acquitted for the first blow (within private defence). He is liable for the second blow (right had terminated, and pursuit was retaliation).
