... In no circumstances whatever shall a prisoner of war be tried by a court of any kind which does not offer the essential guarantees of independence and impartiality as generally recognized, and, in particular, the procedure of which does not afford the accused the rights and means of defence provided for in Article 105. ...

... When fixing the penalty, the courts or authorities of the Detaining Power shall take into consideration, to the widest extent possible, the fact that the accused, not being a national of the Detaining Power, is not bound to it by any duty of allegiance, and that he is in its power as the result of circumstances independent of his own will.
