When Does the Right to Private Defence Begin and End?

Every person has a natural instinct to protect themselves when faced with danger. Indian criminal law formally recognises this instinct through the right of private defence – but it does not give a blank cheque. The law is very specific about when this right kicks in and, equally important, when it must stop. Two provisions under the Indian Penal Code, 1860 – Section 102 (for defence of the body) and Section 105 (for defence of property) – lay down this precise timeline. Understanding these sections is not just an academic exercise; it determines the thin legal line between a justified act of self-defence and a criminal act of aggression.

The governing framework: Sections 102 and 105 IPC 🔗

The right of private defence as a whole is contained in Sections 96 to 106 of the IPC. Within this cluster, Sections 102 and 105 are uniquely concerned with the temporal dimension – they answer the question of timing. Section 102 deals with the defence of the body, while Section 105 deals with the defence of property. Together, they ensure that private defence remains a shield against real and present danger, not a sword used after the threat has passed. With the introduction of the Bharatiya Nyaya Sanhita (BNS) in 2024, these provisions now correspond to Sections 40 and 43 of the BNS respectively, though the substance of the law remains unchanged.

Section 102 IPC: when does the right to defend the body begin and end? 🔗

Section 102 of the IPC reads: “The right of private defence of the body commences as soon as a reasonable apprehension of danger to the body arises from an attempt or threat to commit the offence, though the offence may not have been committed; and it continues as long as such apprehension of danger to the body continues.”

This is a carefully worded provision. Let us break it down into its two key components.

Commencement: reasonable apprehension, not actual harm 🔗

The right does not wait for the first blow to land. It begins the moment a person develops a reasonable apprehension of danger – that is, when a threat or an attempt to commit an offence is made, even if the offence has not yet materialised. The person does not need to wait until they are actually struck or harmed. This is a proactive design: the law allows people to act before injury occurs, so long as the fear of injury is genuine and objectively reasonable.

The word “reasonable” carries significant legal weight here. It is not enough to have a vague sense of unease or a subjective feeling of fear. Courts examine whether a person of ordinary prudence, placed in the same situation, would have experienced the same apprehension. As the Supreme Court clarified in Darshan Singh v. State of Punjab (2010), the right to private defence is a defensive measure, not a retaliatory one, and its invocation depends on genuine and proportionate fear.

Continuation and cessation: the threat must persist 🔗

The right continues only as long as the apprehension of danger continues. The moment the threat disappears – the assailant retreats, drops the weapon, or is overpowered – the right to use defensive force comes to an end. Any force used after the threat has ceased is no longer private defence; it crosses into retaliation, which the law does not protect.

This principle was applied sharply in State of U.P. v. Ram Swarup (1974), where the court held that while defensive force was justified while the threat from a mob persisted, killing an attacker after the danger had already subsided was considered excessive. The judgment made clear that once the cause of reasonable apprehension disappears, the plea of right of private defence can legitimately be negatived.

The concept of reasonable apprehension: what courts look for 🔗

The phrase “reasonable apprehension” is the heart of Section 102. Indian courts have consistently held that this standard is objective, not purely subjective. What matters is not just what the accused felt, but what a reasonable person in the same circumstances would have felt. At the same time, Indian courts also recognise that in high-stress situations, individuals cannot precisely calculate the extent of force required. The law does not expect perfect judgment in the heat of the moment.

However, this latitude has limits. In Kishan v. State of M.P. (2003), the Supreme Court found that the accused had used excessive force disproportionate to the threat, thereby losing the protection of Section 102. The key judicial test is always: was the apprehension genuine, and was the response proportionate? These two questions define whether private defence was lawfully exercised.

Section 105 IPC: when does the right to defend property begin and end? 🔗

Section 105 of the IPC governs the commencement and continuation of the right to defend property. Unlike Section 102, which applies uniformly to all threats to the body, Section 105 has a more nuanced structure – it specifies different end-points depending on the nature of the offence against the property.

Commencement 🔗

The right of private defence of property begins when a reasonable apprehension of danger to the property commences. This mirrors the logic of Section 102 – the threat need not have fully materialised; the apprehension of it is enough.

Continuation: offence-specific rules 🔗

Section 105 then lays down four distinct rules for when the right continues, depending on the type of offence:

Against theft: The right continues until the offender has successfully retreated with the property, or until the assistance of public authorities is obtained, or until the property has been recovered. This means that if a thief is fleeing with stolen goods and has not yet made a safe getaway, the owner still retains the right to act in defence of their property.

Against robbery: The right extends as long as the offender continues to cause or attempts to cause death, hurt, or wrongful restraint, or as long as the fear of instant death, instant hurt, or instant personal restraint persists. Robbery, being more violent than theft, attracts a longer window for defensive action.

Against criminal trespass or mischief: The right continues as long as the offender is still in the act of committing criminal trespass or mischief. Once they leave the premises or stop the mischief, the defensive right ends.

Against house-breaking by night: The right continues for as long as the house-trespass that began with the house-breaking continues. As long as the intruder remains inside the premises, the occupant retains the right of private defence.

Why these timelines matter: the line between defence and excess 🔗

The temporal framework in Sections 102 and 105 serves a critical purpose: it prevents the right of private defence from being weaponised. Without a clear start and end point, this right could be misused to justify preemptive attacks or acts of revenge disguised as self-defence. The law is designed to protect the defender, not empower the aggressor.

This is why the Supreme Court has repeatedly held that the force used in private defence must bear a reasonable proportion to the injury to be averted – it must not be greater than is necessary for the protection of the person or property in question. The right is co-extensive with the threat: it grows with the threat, and it must shrink and disappear as the threat recedes.

In Munshi Ram v. Delhi Administration (1968), the Supreme Court reinforced that when an accused acts in genuine defence of their property against an ongoing invasion, and the response is proportionate, the law fully protects them. The accused’s actions were found justified because the threat had not yet been neutralised at the point when they acted.

Role of public authorities and the duty to seek help 🔗

One of the express conditions under Section 105 (for property defence against theft) is that the right ends once the assistance of public authorities is obtained. This reflects a broader principle running through all of private defence law: private defence is a substitute for state protection, not a preference over it. When police assistance is available and accessible, citizens are expected to seek it. The right of private defence is meant to fill the gap when the state’s protective arm cannot reach in time – it is not an invitation to bypass law enforcement.

As Section 37 of the BNS (formerly Section 99 IPC) explicitly clarifies, there is no right of private defence in cases where there is sufficient time to have recourse to the protection of public authorities. The right becomes available precisely in those moments when there is no time to seek help.

How BNS 2023 treats these provisions 🔗

The Bharatiya Nyaya Sanhita, 2023, which came into force on July 1, 2024, replaces the IPC. Section 40 of the BNS is a faithful reproduction of Section 102 IPC, and Section 43 of the BNS replicates Section 105 IPC, without any substantive change in law. Students and practitioners studying these provisions under the IPC will find the law entirely consistent under the BNS. The transition is largely terminological, and the judicial precedents built under Sections 102 and 105 IPC remain fully applicable to their BNS counterparts.

Key takeaways 🔗

The commencement and continuation of the right of private defence can be summarised cleanly. For bodily defence under Section 102: the right starts with reasonable apprehension of danger and ends when that apprehension disappears. For property defence under Section 105: the right starts with reasonable apprehension of danger to property, but the endpoint varies – it depends on whether the offence is theft, robbery, trespass, mischief, or nocturnal house-breaking. In each case, the right is dynamic: tied to the live reality of the threat, not a static window of time. The moment the threat ends – whether by retreat, recovery, intervention of authorities, or cessation of the act – the right of private defence ends with it. Continuing to use force after this point exposes the defender to criminal liability.

What do you think? If a thief is caught fleeing with stolen property but has not yet left the premises, should the property owner still be allowed to use force to recover it – and how much force is too much? And given that the BNS has retained these provisions unchanged, do you think the law adequately addresses situations where the line between threat and retreat is difficult to identify in practice?
