Whether West Virginia recognizes defense of another as a justification for using force, including deadly force when warranted.
Holding
Yes. West Virginia recognizes defense of another as an extension of self-defense; a person may act to protect a brother or another person to the extent that the person defended could lawfully act in self-defense.
Reasoning
The Court relied principally on State v. Greer, an 1883 decision holding that a person may do for a brother what the person could lawfully do in self-defense when threatened with death or great bodily harm. Greer also explained that if the person being defended provoked the encounter, that person ordinarily must retreat if safely able to do so before another may justifiably use lethal force on that person's behalf.
Later West Virginia decisions had not displaced Greer. Although State v. Collins did not resolve the scope of defense of another because the underlying fight had already ended, it did not reject the doctrine. State v. W.J.B. likewise recognized that self-defense may be invoked in protecting a family member.
The Court also described the generally accepted framework: one who intervenes in another's defense steps into the threatened person's shoes. The intervenor may use no greater force than the threatened person could lawfully have used in self-defense.
