(4)The officer who assembled the Court shall, when the Court is held on a returned prisoner of war or on a prisoner of war who is still absent, direct the Court to record its opinion whether the person concerned was taken prisoner through his own wilful neglect of duty, or whether he served with or under, or aided the enemy; he shall also direct the Court to record its opinion in the case of a returned prisoner of war, whether he returned as soon as possible to the service, and in the case of prisoner of war still absent, whether he failed to return to the service when it was possible for him to do so. The officer who assembled the Court shall also record his own opinion on these points. In other cases, the Court shall give no opinion on the conduct of any person unless so directed by the officer who assembled the Court.
