Homicide – When Justifiable

Homicide is justifiable when committed:

1. In the lawful defense of the slayer, or his or her husband, wife, parent, child, brother, or sister, or of any other person in his or her presence or company, when there is reasonable ground to apprehend a design on the part of the person slain to commit a felony or to do some great personal injury to the slayer or to any such person, and there is imminent danger of such design being accomplished.

Wash. Rev. Code § 9A.16.050 (1)

Washington does not have a law specific to the defense of others, but does allow for the defense of a third person in its defense-of-person law.

Washington Home Defense Law
Homicide is also justifiable when committed:

• In the actual resistance of an attempt to commit a felony upon the slayer, in his or her presence, or upon or in a dwelling, or other place of abode, in which he or she is.

Wash. Rev. Code § 9A.16.050 (2)

A defendant may use necessary force against a malicious trespass or other malicious interference with real or personal property lawfully in that person's possession even though the defendant does not reasonably believe that he is about to be injured. (See State v. Bland)

State v. Bland

Washington does not have any laws specifically related to self-defense immunity.

Washington law:

Although there is no statute on point, the Washington common law supports the circuit majority opinion that there is no duty to retreat from an unlawful threat so long as the actor is free from contributory guilt. (State v. Prado)

Jury instruction No. 22:

It is lawful for a person who is in a place where that person has a right to be and who has reasonable grounds for believing that he is being attacked to stand his ground and defend against such attack by use of lawful force. The law does not impose a duty to retreat.

State v. Prado (2008)

A person may kill a wild animal if it is attacking them or another person. A person may also kill game animals posing an immediate threat of physical harm to themselves or another person. The conditions for killing wildlife to protect property vary, based primarily on the classification of the wildlife species, the imminent nature of the threat of damage to private property, the type of private property damage, and the preventive and nonlethal methods employed by that person prior to the damaging event. It is unlawful to kill protected wildlife or endangered species (as defined in Wash. Rev. Code 77.08.010) unless authorized by commission rule or a permit. It is permissible to kill unclassified wildlife, predatory birds, and game animals that are in the act of damaging commercial crops or attacking livestock or other domestic animals if a number of specific conditions are met.

Wash. Admin. Code § 220-440-060
