Introduction of BNS 43
BNS 43 of the Bharatiya Nyaya Sanhita highlights an important safeguard for every individual—the right to protect their property. It ensures that the law recognizes your authority to act when your home, land, or belongings are under threat. This section replaces the earlier IPC Section 105 and clarifies when the right begins, how long it lasts, and the circumstances in which you can exercise it. Whether it is theft, robbery, trespass, mischief, or house-breaking, BNS Section 43 empowers you to defend what is rightfully yours, provided your actions remain reasonable and proportionate to the threat.
The Bharatiya Nyaya Sanhita (BNS) Section 43 replaces the old Indian Penal Code (IPC) Section 105.
What is section 43 of BNS ?
BNS Section 43 says that you can protect your property if you believe it is in danger. This right to defend your property starts as soon as you feel there is a real threat, and it continues as long as the danger exists. This applies to situations like theft, robbery, trespassing, or someone breaking into your house.

BNS Section 43 explanation
BNS Section 43 provides clarity on when the right of private defence of property begins and how long it continues. It ensures that a person can immediately act to safeguard their property from theft, robbery, trespass, mischief, or house-breaking, and specifies the circumstances in which this right ends.
(This provision corresponds to IPC Section 105, updated under the Bharatiya Nyaya Sanhita (BNS), 2023.)
1. Meaning of Section 43
BNS Section 43 defines the time frame and duration of the right of private defence of property.
- The right begins as soon as there is a reasonable fear of theft, robbery, trespass, mischief, or house-breaking.
- It continues only while the danger persists and ends once the offender withdraws, the property is recovered, or law enforcement takes charge.
This ensures that the right to defend property is immediate and effective, but not indefinite.
2. Purpose of Section 43
The aim of this section is to provide legal certainty about how long a person can defend their property.
- It prevents misuse of the right by making clear that it does not continue once the danger has ceased.
- It balances the need for quick, lawful protection of property with the principle that force should not continue after the threat is over.
3. Essential Ingredients of Section 43
For the right under this section to apply, the following conditions must be satisfied:
- Commencement: The right begins the moment there is a reasonable apprehension of harm to property.
- Continuance:
- Against theft: lasts until the thief escapes with property, or the property is recovered, or public authorities intervene.
- Against robbery: continues as long as the robber threatens or causes harm.
- Against trespass/mischief: continues as long as the trespasser or wrongdoer remains on the property or causes damage.
- Against house-breaking at night: lasts until the intruder remains inside the premises.
- Proportionality: The force used must be reasonable and proportionate to the nature of the threat.
- Cessation: Once the threat ends, the right immediately stops.
4. Punishment under BNS Section 43
There is no punishment when a person acts within the limits of Section 43, because such defence is lawful.
However, if someone exceeds the right — for example, continuing to harm an offender after the threat has ended — then the act will not be protected, and the person may face criminal liability (like assault, grievous hurt, or even homicide, depending on the act).
5. Examples of Section 43 in Action
- Example 1 (Theft): A man catches a thief stealing his bike. He pulls the thief down and restrains him until police arrive. This is lawful under Section 43.
- Example 2 (Robbery): During a robbery, the shopkeeper fights back and prevents the robbers from escaping. His right to defence continues until the robbers stop threatening violence.
- Example 3 (Trespass): A farmer stops intruders from damaging his crops while they are still inside his land. This defence is valid.
Counter-Example 1: A trespasser leaves the property, but the owner chases and beats him afterwards. This is not protected under Section 43, because the right ends once the trespass is over.
Counter-Example 2: A thief drops the stolen goods and runs away. If the property owner continues to harm him despite recovery of the goods, it will be treated as an offence.
6. Importance of Section 43
BNS Section 43 is significant because it clearly defines the limits of private defence of property.
- It empowers citizens to act swiftly in cases of theft, robbery, trespass, or house-breaking.
- At the same time, it ensures that once the threat is over, no excessive or retaliatory action is taken.
- By laying down exact conditions of commencement and continuance, this section promotes justice, restraint, and accountability in the exercise of private defence.
Section 43 of Bharatiya Nyaya Sanhita
BNSS Section 43 makes it clear that the right to defend property begins as soon as there is a real and reasonable threat to it and lasts until the danger is completely gone. This ensures that property owners can protect their belongings during theft, robbery, trespass, or house-breaking, but they must also stop once the threat ends.
Right Starts with Threat:
Your right to defend your property begins the moment there is a reasonable fear that someone may steal, damage, or unlawfully enter it. You do not need to wait until the crime is fully committed. For example, if someone tries to break open your shop shutter, you can act immediately.
Defense During Theft:
If someone is stealing your property, your right to defense continues until the thief either escapes with the property, you successfully recover it, or the authorities arrive to help. This ensures that you can lawfully act while the theft is still happening.
Robbery Defense:
In cases of robbery, your right to defend your property lasts as long as the robber continues to threaten or use violence. Once the threat of harm to you or others ends, your right to use force also ends.
Against Trespassers:
If someone unlawfully enters your land or house, or tries to damage your belongings, your right to defend continues as long as they remain on your property. Once they leave, the right ends.
Night-Time House-Breaking:
If someone breaks into your house during the night, your right to defend your home lasts until they remain inside or until the threat is fully over. This provision recognizes the serious fear caused by night-time intrusions.
Property in Danger:
The right begins as soon as there is a reasonable fear of danger to the property, even before actual harm occurs. For example, if a group is approaching your house with the intention to break in, you can prepare to defend it.
Using Force:
You can use force to protect your property, but the level of force must match the seriousness of the threat. Minor trespass should be met with minimal force, while violent robbery may justify stronger action.
Continuing Danger:
Your right to defend lasts as long as the danger is present. Once the offender has left or the property is safe, your right to use force ends. Continuing to harm someone after the threat is gone will not be considered self-defense.
Legal Protection:
The law protects individuals who act in defense of their property within the limits of this section. As long as your actions are reasonable and proportionate, you are legally safe from punishment.
Immediate Response:
You must act promptly when property is in danger. The law expects you to defend it when the threat is real and present, not after the danger has already passed. Quick action is what makes your defense lawful.
