The military judge in a military commission under this chapter shall rule upon all questions of law, including the admissibility of evidence and all interlocutory questions arising during the proceedings.

Any ruling made by the military judge upon a question of law or an interlocutory question (other than the factual issue of mental responsibility of the accused) is conclusive and constitutes the ruling of the military commission. However, a military judge may change such a ruling at any time during the trial.

that the accused must be presumed to be innocent until the accused’s guilt is established by legal and competent evidence beyond a reasonable doubt;

that in the case being considered, if there is a reasonable doubt as to the guilt of the accused, the doubt must be resolved in favor of the accused and the accused must be acquitted;

that, if there is reasonable doubt as to the degree of guilt, the finding must be in a lower degree as to which there is no reasonable doubt; and

that the burden of proof to establish the guilt of the accused beyond a reasonable doubt is upon the United States.
