California Self Defense Laws
The right to use force -- even deadly force if necessary -- to defend oneself is a broadly accepted principle of the criminal justice system. But while all states allow defendants to claim self defense if they can back up such claims, states differ on the scope of what may be considered appropriate use of force and when it may be applied. For instance, some states have what are commonly referred to as "stand your ground" laws, which essentially do away with the duty to retreat from imminent danger. In states with these types of laws, individuals have the affirmative right to use deadly force to defend themselves regardless of where they are or whether they had an opportunity to retreat.
California Self Defense: The Castle Doctrine
California is not a stand your ground state, but does recognize the "castle doctrine," which applies to one's home, place of business, or other real property. Similarly, an individual using deadly force to protect his or her property has no duty to retreat. But castle doctrine rights end when an individual is no longer on his or her real property. As a general rule of thumb, any force used against an intruder must be proportionate to the harm reasonably feared.
Self Defense and California Jury Instructions
In addition to the affirmative defense provided by the castle doctrine, the Judicial Council of California provides jury instructions for how to assess a defendant's claim of self defense. While the main points of these instructions are highlighted below, it's important to point out that the right to use force in self defense (or in defense of another) ends "when the attacker withdraws or no longer appears capable of inflicting any injury."
