It is lawful to repel force with force.

Explanation

Self-defense is a natural right — a man may use proportionate force to defend his life, limb, or property against unlawful aggression without waiting for the aid of the law.

Where this applies

• Someone defends themselves from an attacker and is charged with assault.
• A homeowner uses force against an intruder who broke into their house.
