The Supreme Court granted review in this case to determine whether one who kills in the actual but unreasonable belief he must protect another person from imminent danger of death or great bodily injury is guilty of voluntary manslaughter and not murder. The Court of Appeal reversed appellant’s second degree murder conviction because the trial court erred in refusing to instruct on the imperfect defense of another. The Supreme Court affirmed that reversal, finding that the trial court prejudicially erred when it refused to instruct the jury on the doctrine of imperfect defense of others. Further, it was error under the circumstances of this case for the trial court to have instructed the jury that it could convict of second degree felony murder based on appellant’s discharge of a firearm in a grossly negligent manner.
