The right of private defence is a fundamental principle in criminal law that allows individuals to protect their life, liberty, and property against unlawful harm. Recognized under the Indian Penal Code, this right empowers a person to take necessary actions to prevent or repel an attack when immediate protection from public authorities is not available. However, the exercise of this right is carefully regulated by law to ensure that the response remains proportionate to the threat faced. The extent of this right to be exercised in respect of body in covered from section 38 to 40 BNS.
The right of private defence is a vital principle in criminal law that allows individuals to protect their life and personal safety from unlawful aggression. In situations where immediate assistance from public authorities is unavailable, the law recognizes that a person may need to take necessary steps to defend themselves or others from harm. This principle has long been an essential part of Indian criminal jurisprudence and continues to be recognized under the Bharatiya Nyaya Sanhita, 2023.

Right of Private Defence of Body:
Under the Bharatiya Nyaya Sanhita (BNS), provisions relating to private defence ensure that individuals are legally empowered to safeguard their body and liberty when faced with an imminent threat. The law acknowledges that self-preservation is a natural and fundamental instinct, and therefore grants individuals the right to use reasonable force to prevent unlawful acts such as assault, grievous hurt, or other forms of violence.
The right of private defence of the body is not unlimited; it is carefully regulated to prevent misuse. The law specifies the circumstances under which the right arises, the extent of force that may be used, and the situations in which this right may extend even to causing death. These provisions aim to strike a balance between protecting individuals from immediate danger and maintaining public order by ensuring that the force used in defence remains proportionate and necessary. This article aims to examine the concept, scope, and limitations of the right of private defence of the body under the Bharatiya Nyaya Sanhita, along with its legal significance and practical application in safeguarding individual security.
Section 38 BNS:
When Right of Private Defence of Body Extends to Causing Death:
The right of private defence of the body extends, under the restrictions specified in section 37, to the voluntary causing of death or of any other harm to the assailant, if the offence which occasions the exercise of the right be of any of the descriptions hereinafter enumerated, namely:—
(a) such an assault as may reasonably cause the apprehension that death will otherwise be the consequence of such assault;
(b) such an assault as may reasonably cause the apprehension that grievous hurt will otherwise be the consequence of such assault;
(c) an assault with the intention of committing rape;
(d) an assault with the intention of gratifying unnatural lust;
(f) an assault with the intention of wrongfully confining a person, under circumstances which may reasonably cause him to apprehend that he will be unable to have recourse to the public authorities for his release;
(g) an act of throwing or administering acid or an attempt to throw or administer acid which may reasonably cause (e) an assault with the intention of kidnapping or abducting.
Among the provisions governing private defence, Section 38 of the Bharatiya Nyaya Sanhita, 2023 (BNS) occupies a significant place. While the general rule discourages causing death or serious harm, Section 38 BNS recognizes that in certain extreme circumstances, the threat to an individual’s safety may be so grave that causing the death of the aggressor becomes legally justified. The section deals with the death caused when applying the defence under this section are as follows:
- Where apprehension is so severe that death is sure or such intimidation is present.
- Where the apprehension that grievous hurt might occur and consequence of which might cause death.
- When the offender the tries to commit the offence of rape to an individual.
- In cases of gratification of unnatural lust, specifically with an intention of doing so.
- An attempt of kidnapping or abduction might also give rise to the defence under this section.
- When there is a wrongful confinement and that the recourse under the help of public authorities will not be provided then one may be capable of taking the aid of this section.
- An act or attempt of causing deformation by spilling acid on the individual then under such severe circumstances the person can cause death in order to protect himself.
Conditions to Invoke the Provisions of Section 38 BNS:
- The person exercising the right of private defence must be free from fault in bringing about the encounter;
- There must be an impending peril to life or of great bodily harm;
- There must be no safe or reasonable mode of escape by retreat; and
- There must have been a necessity for taking life.
A mere apprehension of grievous nature is enough to proceed under this section.
This section reflects the law’s attempt to balance two important objectives: protecting individuals from serious and immediate danger while preventing the misuse of defensive force. By clearly outlining the circumstances in which lethal force may be justified, Section 38 BNS provides legal clarity and safeguards the rights of those acting in genuine self-defence.
Section 39:
When Such Right Extends to Causing any Harm Other than Death:
If the offence be not of any of the descriptions specified in section 38, the right of private defence of the body does not extend to the voluntary causing of death to the assailant, but does extend, under the restrictions specified in section 37, to the voluntary causing to the assailant of any harm other than death.
If an offense is not listed in Section 38 BNS (which allows causing death in self-defense), the right to private defence of the body does not allow causing the assailant’s death, but permits causing any other harm, subject to constraints. Any harm caused must be proportional to the threat and restricted by the limitations mentioned in Section 37 BNS.
Section 40:
Commencement and Continuance of Right of Private Defence of Body:
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.
The apprehension of danger must be reasonable, not fanciful.
Examples:
- A person named A suddenly pulls out a knife and threatens to stab B while moving toward him. Even before A actually attacks, B develops a reasonable fear of being harmed. At this moment, B’s right of private defence begins, and B may take necessary steps to protect himself.
- A begins beating B with a stick, causing serious injury. B pushes A away and strikes him in order to escape the attack. Here, B’s right of private defence continues while the assault is ongoing, because the danger to B’s body still exists.
- Suppose A attacks B but then runs away and is no longer capable of causing harm. If B chases A and attacks him afterward, the right of private defence would no longer apply, because the immediate threat has already ended.
- If A tries to forcibly drag B into a vehicle to kidnap him, B may resist and use necessary force to protect himself. The right of private defence begins as soon as the attempt to kidnap creates a reasonable fear for B’s safety or liberty.
- If A holds B at gunpoint and prevents him from leaving, the threat to B’s life continues. B’s right of private defence remains active until the danger is removed, such as when A drops the weapon or B safely escapes.
- A points a knife at B. B manages to disarm A and the knife falls to the ground. If B continues to severely assault A after he is disarmed and no longer threatening, the right of private defence ends at the moment the danger stops.
- A attempts to kidnap B and tries to drag him into a vehicle. B pushes A away and successfully escapes to a safe place. If B later returns to attack A, he cannot claim private defence, because the threat has already ceased.
- If A assaults B but police arrive and restrain A, B cannot continue to attack A. The right ends once lawful authorities have intervened and the danger is removed.
- If A attacks B but B knocks A unconscious in self-defence, the threat is no longer present. Any further harm caused by B after that point cannot be justified as private defence.
Judicial Analysis:
In Re: Ganpathia Pillai AIR 1953 Madras 936 case, the Madras High Court observe that the right of private defence of body commences,’ as soon as, a reasonable apprehension of the danger to the body arises from an attempt or threat to commit the offence, although the offence may not have been committed and lasts till such reasonable apprehension lasts.
In Yeswanth Rao v. State of Madhya Pradesh, AIR 1992 SC 1683 case, where the minor daughter of the accused was sexually molested by the deceased. After seeing this he hit the deceased with a spade. He died due to injury of the liver. The supreme court held that since the girl was a minor , the question of consent does not arise and the act of the deceased would amounts to rape and hence father is in the defence of the body of his daughter, was justified in exercising his right of private defence.
In Munney Khan v. the State of M.P., AIR 1971 SC 1491 case, the deceased picked up a quarrel with the appellant’s brother, that the deceased overpowered the appellant’s brother, threw him on the ground and sat on his chest giving him fist blows, and that since the appellant could not, prevent the deceased hitting his brother by the use of his fist, he stabbed the deceased in the back with a knife. The trial court found the appellant guilty of murder, and the High Court dismissed his appeal summarily, agreeing generally with the conclusions of the trial court. The Court held that the appellant had exceeded his right of private defence and his guilty of culpable homicide not amounting to murder punishable under the first part of s.304, IPC. The court observed that the right of private defence is defensive and neither vindictive nor retributive.
In Naveen Chandra v. State of Uttaranchal, 2007 CrLj 874 (SC) case, the Court held that Sections 102 and 105, IPC deal with commencement and continuance of the right of private defence of body and property respectively. The right commences, as soon as a reasonable apprehension of danger to the body arises from an attempt, or threat, to commit the offence, although the offence may not have been committed but not until there is that reasonable apprehension. The right lasts so long as the reasonable apprehension of the danger to the body continues.
In Jai Dev. v. State of Punjab, AIR 1963 SC 612 case, it was observed that as soon as the cause for reasonable apprehension disappears and the threat has either been destroyed or has been put to route, there can be no occasion to exercise the right of private defence.
Conclusion:
The right of private defence of the body is an essential safeguard that protects individuals from unlawful harm and immediate threats to their personal safety. Recognized under the Bharatiya Nyaya Sanhita, 2023, this right empowers a person to take necessary and reasonable action to defend themselves or others when faced with imminent danger. It reflects the legal principle that the law does not expect a person to remain passive when their life, liberty, or physical safety is under serious threat.
However, the exercise of this right is subject to clear limitations. The force used in self-defence must be proportionate to the threat, and the right exists only as long as there is a reasonable apprehension of danger. Once the threat ceases, the justification for using force also ends. These limitations ensure that the doctrine of private defence remains a protective mechanism rather than a means of retaliation or misuse.
