Practice Relating to Rule 156. Definition of War Crimes
In the Cantos case before the Philippine Supreme Court in 1946, the Court dismissed (in a majority opinion) a petition for habeas corpus made by a Japanese/Philippine civilian, finding that the petitioner was subject to the jurisdiction of a US military commission. In its judgment, the Court noted:
It is well settled that war crimes may be committed not only by lawful belligerents but by any “men and bodies of men, who, without being lawful belligerents” “nevertheless commit hostile acts of any kind.” (Par. 351, Rules of Land Warfare.) “Persons of the enemy territory who steal within the lines of hostile army for the purpose of robbing, killing, etc.” are also war criminals subject to the jurisdiction of military commissions. (Par. 352, id., id.) And in the preamble to the Hague Convention it is declared that “until a more complete code of the laws of war has been issued, the High Contracting Parties deem it expedient to declare that, in cases not included in the Regulations adopted by them, the inhabitants and the belligerents remain under the protection and the rule of the principles of the law of nations, as they result from the usages established among civilized peoples, from the laws of humanity, and the dictates of the public conscience.”
Here, the petitioner is a Filipino citizen though of a Japanese father, and associating himself with Japan in the war against the United States of America and the Philippines, committed atrocities against unarmed and noncombatant Filipino civilians and looted Filipino property. He is, indeed, a war criminal subject to the jurisdiction of the military commission, and his confinement by the respondent is not illegal. (In re Yamashita, 66 Sup. Ct., 340; 90 Law. ed., 499.)
