حق دفاع, or the "right to defense," refers to the legal principle that allows individuals to protect themselves from harm. This right is recognized in many legal systems and is often invoked in situations where a person faces an imminent threat. The concept emphasizes that individuals can take necessary actions to defend themselves, their property, or others when faced with aggression. In many jurisdictions, the right to defense is subject to certain limitations. For instance, the response must be proportional to the threat faced. Legal frameworks, such as those in criminal law, outline the conditions under which self-defense is justified, ensuring that individuals do not misuse this right.
