As to Foster's contention that he was entitled to have the jury instructed on defense of others, we hold that the trial court did not err in refusing the instruction. Foster's tendered instruction was an erroneous statement of the Virginia law. However, because the issue will necessarily arise on remand, we address what is the state of the law in Virginia on defense of others. The Supreme Court has clearly recognized that one is privileged to use force in defense of family members. See Newberry v. Commonwealth, 191 Va. 445, 459, 61 S.E.2d 318, 324 (1950); Green v. Commonwealth, 122 Va. 862, 871, 94 S.E.940, 942 (1918); Hodges v. Commonwealth, 89 Va. 265, 272, 15 S.E. 513, 516 (1892). We find no Virginia cases, nor have any been cited to us, determining whether and when a person can use force to protect or defend a third person. Generally, however, this privilege is not limited to family members and extends to anyone, even a stranger who is entitled to claim self-defense. See 40 Am. Jur. 2d Homicide § 170 (1968); In re Neagle, 135 U.S. 1, 75-76 (1890); State v. Saunders, 330 S.E.2d 674, 675, 76 (W. Va. 1985); Yardley v. State, 100 S.W. 399, 400 (Tex. Crim. App. 1907); State v. Bowers, 65 S.C. 207, ___ , 43 S.E. 656, 657-58 (1903); Stanley v. Commonwealth, 86 Ky. 440, ___, 6 S.W. 155, 155-57 (1887); Mitchell v. State, 22 Ga. 211, 234 (1857). Like self-defense, the circumstances in which the protection of others may be raised as a defense are carefully circumscribed so as to preclude such a claim in situations where one has instigated the fray in order to provide an excuse for assaulting or murdering his enemy. In a majority of jurisdictions, a person asserting a claim of defense of others may do so only where the person to whose aid he or she went would have been legally entitled to defend himself or herself. 40 Am. Jur. 2d Homicide § 171 (1968). Thus, the right to defend another “is commensurate with self-defense.” Id. Consequently, in those jurisdictions which recognize the defense, the limitations on the right to defend one's self are equally applicable, with slight modifications, to one's right to defend another. One must reasonably apprehend death or serious bodily harm to another before he or she is privileged to use force in defense of the other person. The amount of force which may be used must be reasonable in relation to the harm threatened. See Diffendal, 8 Va. App. at 421, 383 S.E.2d at 25-26 (delineating limitations in self-defense context).
Jurisdictions which recognize the defense are split on the question whether the person to whose aid one comes must be free from fault in order to claim the defense of protection of others. The majority of those courts which have addressed the question have adopted an objective test so that one “may act on and is governed by the appearance of conditions when he arrives upon the scene, provided he acts honestly and according to what seems reasonably necessary in order to afford protection.” 40 Am. Jur. 2d Homicide § 172 (1968). Thus, under the majority view, in order to justifiably defend another, the defendant must reasonably believe that the person being defended was free from fault; whether the defended person was, in fact, free from fault is legally irrelevant to the defense in those jurisdictions. This view is based on the principle that one should not be convicted of a crime for attempting to protect one whom he or she perceives to be a faultless victim from a violent assault. Under this approach, the policy of the law is to encourage individuals to come to the aid of perceived victims of assault. Id. We find this position to be well-grounded in principle and policy. Accordingly, we hold that the law pertaining to defense of others is that one may avail himself or herself of the defense only where he or she reasonably believes, based on the attendant circumstances, that the person defended is without fault in provoking the fray.
