Self-defense is a justifying circumstance that frees a person from criminal liability when they repel an unlawful attack, and it has three requisites: unlawful aggression on the part of the victim; reasonable necessity of the means employed to prevent or repel it; and lack of sufficient provocation on the part of the person defending themselves. Unlawful aggression is the indispensable requisite; without an actual or imminent unlawful attack on one's life or limb, there is nothing to defend against and self-defense cannot be invoked. A closely related question is defense of property. Property rights may be defended, but the law and jurisprudence draw an important line: the defense of property is not of such importance as the right to life, so as a rule, defense of property alone does not justify the taking of a human life or the infliction of serious harm. The use of deadly force to protect mere property, when there is no accompanying attack on the person, is generally not justified and may make the defender liable. However, where the attack on property is coupled with an actual or imminent threat to the life or safety of the owner or possessor (for example, a violent home invasion where the intruder endangers the occupants), the situation becomes one of self-defense or defense of person, and reasonable, even deadly, force may be justified against the aggression to the person. The reasonableness of the means is always judged by the circumstances, not with the calm of hindsight. So one may defend property, but deadly force is generally justified only when a person's life or safety is also under unlawful attack.
The Requisites of Self-Defense
- Unlawful aggression by the victim (indispensable);
- Reasonable necessity of the means to repel it; and
- Lack of sufficient provocation by the defender.
Defense of Property Alone
Property may be defended, but the right to life outweighs property. As a rule, defense of property alone does NOT justify killing or serious harm; deadly force for mere property generally makes the defender liable.
When Deadly Force Is Justified
When the attack on property is coupled with a threat to the person (e.g., a violent home invasion endangering the occupants), it becomes self-defense, and reasonable, even deadly, force may be justified. Reasonableness is judged by the circumstances, not hindsight.
Practical Takeaways
- Unlawful aggression is indispensable to self-defense;
- Property alone generally does not justify deadly force;
- A threat to life or safety alongside property can justify self-defense.
Frequently Asked Questions
What are the requisites of self-defense? Unlawful aggression by the victim, reasonable necessity of the means employed to repel it, and lack of sufficient provocation on the part of the person defending. Unlawful aggression is indispensable.
Can I use deadly force to protect my property? Generally no, if only property is at stake. The right to life outweighs property, so defense of property alone does not justify killing or serious harm, and deadly force for mere property may make you liable.
When is deadly force justified in a home invasion? When the intrusion is coupled with an actual or imminent threat to the life or safety of the occupants. The situation then becomes self-defense or defense of person, where reasonable, even deadly, force may be justified.
How is the reasonableness of the force judged? By the circumstances as they appeared to the person defending at the time, not with the calm of hindsight, weighing the nature and imminence of the aggression against the means used to repel it.
