The theory of command responsibility is established in the field of international humanitarian law. The practical problems for the application of the theory were especially highlighted in the General Yamashita case, decided by a United States military commission in Manila in October 1945. Defence counsel in the case stated that the theory, as relied upon by the commission, was new law at that point in time, because it asserted that criminal responsibility of a commander would arise even if he was relevant to the crimes committed by his subordinates only by reason of his capacity qua their commander.
