In this comprehensive article, we will delve into the intricacies of Section 100 IPC, exploring its various aspects, implications, and the conditions that must be met for justifiable use of lethal force.

Understanding Section 100 IPC

Section 100 of the IPC provides individuals with the legal authority to use force, including deadly force, to protect their own lives or the lives of others under specific circumstances. It is essential to emphasize that this right is not absolute and must meet certain criteria to be considered justifiable.

Imminent Threat

One of the key conditions under Section 100 is the presence of an imminent threat. This means that the danger must be immediate and unavoidable. Individuals cannot resort to deadly force if the threat is not immediate.

Reasonable Apprehension

To invoke the right of private defense extending to causing death, there must be a reasonable apprehension of death or grievous bodily harm. This condition ensures that the use of lethal force is proportionate to the perceived threat.

No Safer Alternative

The law requires individuals to exhaust all reasonable alternatives before resorting to deadly force. If there is a safer option available, using lethal force may not be considered justifiable.


The principle of proportionality dictates that the force used should be proportional to the threat faced. Excessive force is not permissible under Section 100.

Scenarios Where Section 100 Applies

Assault with Deadly Weapons

When faced with an assailant armed with a deadly weapon, individuals may use lethal force to protect themselves or others.

Protecting Others

Section 100 also applies when one intervenes to protect another person who is under imminent threat of death or grievous bodily harm.

Attempted Murder

If someone is attempting to murder another, the victim can invoke Section 100 to defend themselves.

Controversies Surrounding Section 100 IPC


The interpretation of Section 100 has been a subject of debate. Courts often have to decide whether the use of lethal force was genuinely justifiable in a given situation.


There have been instances of individuals misusing this provision to justify acts of violence. Striking the right balance between self-defense and misuse is a constant challenge.


In conclusion, Section 100 IPC plays a crucial role in defining the right of private defense when it extends to causing death. It is a legal provision that seeks to balance the need for self-preservation with the requirement for proportionality and reasonableness. Understanding the conditions and limitations of this provision is vital for individuals to exercise their right of self-defense responsibly and within the boundaries of the law.
