What does the legal concept of justification in self-defense require?

The legal concept of justification in self-defense centers around the necessity of using reasonable force in response to an imminent threat of unlawful force. This means that for an action to qualify as justifiable self-defense, the person must be facing an immediate danger that warrants a defensive response. The force used must be proportional to the threat, meaning it should not exceed what is necessary to protect oneself from harm.

In scenarios where an individual is confronted with unlawful aggression, the law recognizes their right to defend themselves, but this is only justified when the threat is immediate. For self-defense claims to hold in court, the individual must demonstrate that they acted out of a need to avert a specific and present danger. This principle is designed to prevent individuals from taking unlawful action in situations that do not warrant it and ensures that defensive measures are only taken when genuinely needed for protection.
