IPC Section 105 and BNS Section 43: When Private Defence of Property Begins and Ends
Section 105 of the Indian Penal Code, 1860 explained the commencement and continuance of the right of private defence of property. Its corresponding provision under the Bharatiya Nyaya Sanhita, 2023 is Section 43.
IPC Section 105: Original statutory provision
Commencement and continuance of the right of private defence of property.
The right of private defence of property commences when a reasonable apprehension of danger to the property commences.
The right of private defence of property against theft continues till the offender has effected his retreat with the property or either the assistance of the public authorities is obtained, or the property has been recovered.
The right of private defence of property against robbery continues as long as the offender causes or attempts to cause to any person death or hurt or wrongful restraint or as long as the fear of instant death or of instant hurt or of instant personal restraint continues.
The right of private defence of property against criminal trespass or mischief continues as long as the offender continues in the commission of criminal trespass or mischief.
The right of private defence of property against house-breaking by night continues as long as the house-trespass which has been begun by such house-breaking continues.
BNS Section 43: Current corresponding provision
Section 43 of the Bharatiya Nyaya Sanhita, 2023 specifies when the right begins and how long it continues:
- It commences when a reasonable apprehension of danger to the property commences.
- Against theft, it continues until the offender has retreated with the property, assistance of public authorities is obtained, or the property has been recovered.
- Against robbery, it continues while the offender causes or attempts death, hurt or wrongful restraint, or while fear of instant death, hurt or personal restraint continues.
- Against criminal trespass or mischief, it continues while the offender continues committing the offence.
- Against house-breaking after sunset and before sunrise, it continues while the house-trespass begun by that house-breaking continues.
The principal wording update in clause (e) describes house-breaking after sunset and before sunrise, rather than the older IPC expression house-breaking by night.
How long does the right continue?
| Offence or danger | When the right continues or ends |
|---|---|
| Threat to property | Begins with reasonable apprehension of danger; no completed offence is required. |
| Theft | Continues until the offender retreats with the property, public authorities assist, or property is recovered, as stated in the statute. |
| Robbery | Continues while specified violence, attempted violence, restraint or fear of instant harm persists. |
| Criminal trespass or mischief | Continues while commission of the offence continues. |
| House-breaking after sunset and before sunrise | Continues while the resulting house-trespass continues. |
Restrictions: Private defence is not unlimited
BNS Section 37 (corresponding to IPC Section 99) restricts the right, including where there is time to seek protection from public authorities and where harm inflicted exceeds what is necessary for defence. The precise statutory qualifications concerning acts of public servants must also be considered.
BNS Sections 41 and 42 (corresponding to IPC Sections 103 and 104) distinguish the exceptional circumstances in which private defence of property may extend to causing death from circumstances permitting harm other than death. Section 43 governs duration; it does not independently authorize deadly force.
Practical illustrations
Theft of a bag
A person reasonably apprehends an imminent theft and acts to prevent it. Whether subsequent force is protected depends on the continuing circumstances and the limits on necessary force. The provision does not authorize punishment after the defensive necessity ends.
Ongoing criminal trespass
Where a person continues an unlawful trespass, the statutory right may continue while the offence is being committed. The force used must still satisfy the applicable restrictions.
Robbery involving threats of immediate violence
Where a robber continues to threaten instant hurt or restraint, the statutory right may continue during that threat. The level of permissible force is assessed separately under the other private-defence provisions.
Frequently asked questions
What is the BNS equivalent of IPC Section 105?
Section 43 of the Bharatiya Nyaya Sanhita, 2023.
Does private defence begin only after property is stolen?
No. It begins when reasonable apprehension of danger to property begins, subject to statutory restrictions.
Can a property owner cause death to stop every theft?
No. The circumstances permitting deadly force are separately and narrowly governed by BNS Section 41; BNS Sections 37 and 42 are also relevant.
Does the right continue after the danger has ended?
The right is defensive, not punitive. Its duration is governed by the offence-specific conditions in Section 43 and the restrictions in Section 37.
