Self-Defence Laws
Self-defence is a legal principle that allows a person to protect themselves, others, or their property from imminent harm without facing criminal liability. In India, self-defence is mainly governed by the Indian Penal Code (IPC), specifically Sections 96–106, which cover the right of private defence.
1. Legal Provisions in IPC
1. Right to Private Defence of Body (Section 96–100 IPC)
Every person has the right to defend themselves from unlawful attacks.
Section 99 IPC: Right to private defence has limitations; it must be proportional to the threat.
2. Right to Private Defence of Property (Sections 100–106 IPC)
One may defend property from theft, robbery, mischief, trespass.
Deadly force is not justified if the threat is not lethal.
3. Key Points
Threat must be imminent and unlawful.
Defence must be necessary and proportional.
The law distinguishes between:
Private defence of the body
Private defence of property
Excessive force may lead to criminal liability, even if the original attack was unlawful.
