Six years ago in Murray v. State, 937 So.2d 277, 279 (Fla. 4th Dist. 2006), the Fourth District Court of Appeal in Florida ruled that once a defendant in a criminal case has introduced proof that he acted in self-defense the jury is entitled to consider the defense, and the jury may not convict the defendant unless it finds beyond a reasonable that he did not act in self-defense. The Fourth District Court of Appeal stated:
But, with these additional facts, did he also incur a 'burden of proof' identical to the State's? That is, did he have to prove the additional facts for self-defense beyond a reasonable doubt? Or was he instead bound by some lesser standard-say, the greater weight of the evidence? Indeed, how about something even less onerous than that? Was he merely obligated to lay the additional facts before the jury, without any burden as to the strength of their probative value - other than they might be true? The answer is this. No, he did not have to prove self-defense beyond a reasonable doubt. He did not have to prove even that his additional facts were more likely true than not. The real nature of his burden concerning his defense of justification is that his evidence of additional facts need merely leave the jury with a reasonable doubt about whether he was justified in using deadly force. Hence, if he wanted his self-defense to be considered, it was necessary to present evidence that his justification might be true. It would then be up to the jury to decide whether his evidence produced a reasonable doubt about his claim of self-defense.
