Kuroda vs. Jalandoni G.R. no. L-2662. March 26, 1949. Moran, C.J. FACTS: Shigenori Kuroda, formerly a Lieutenant-General of the Japanese Imperial Army and Commanding General of the Japanese Imperial Forces in The Philippines during a period covering 1943 and 1944 who is now charged before a military Commission convened by the Chief of Staff of the Armed forces of the Philippines with having unlawfully disregarded and failed "to discharge his duties as such command, permitting them to commit brutal atrocities and other high crimes against non-combatant civilians and prisoners of the Imperial Japanese Forces in violation of the laws and customs of war" — comes before this Court seeking to establish the illegality of Executive Order No. 68 on the grounds, among others, that the Philippines is not a signatory nor an adherent to the Hague Convention on Rules and Regulations covering Land Warfare and therefore petitioners is charged of 'crimes' not based on law, national and international.” ISSUE: Whether or not E.O. no. 68 is unconstitutional. RULING: No, E.O. no. 68 is valid and constitutional. Under Section3, Article 2 of our Constitution, the Philippines renounces war as an instrument of national policy and adopts the generally accepted principles of international law as part of the of the nation. It cannot be denied that the rules and regulation of the Hague and Geneva conventions form, part of and are wholly based on the generally accepted principals of international law. In fact, these rules and principles were accepted by the two belligerent nation the US and Japan who were signatories to the two Conventions. Such rule and principles, therefore, form part of the law of our nation even if the Philippines was not a signatory to the conventions embodying them for our Constitution has been deliberately general and extensive in its scope and is not confined to the recognition of rule and principle of international law as continued in treaties to which our government may have been or shall be a signatory. Furthermore, when the crimes charged against petitioner were allegedly committed, the Philippines was under the sovereignty of the US and thus, we were equally bound together with the US and with Japan to the right and obligation contained in the treaties between the belligerent countries. These rights and obligation were not erased by our assumption of full sovereignty. If at all our emergency as a free State entitles us to enforce the right on our own of trying and punishing those who committed crimes against our people. In this connection, it is well to remember what we have said in the case of Laurel vs. Misa: The change of our form of government from Commonwealth to Republic does not affect the prosecution of those charged with the crime of treason committed during then Commonwealth because it is an offense against the same sovereign people. By the same token, war crimes committed against our people and our government while we were a Commonwealth are triable and punishable by our present Republic. Additionally, the promulgation of said executive order is an exercise by the President of his power as Commander in chief of all our armed forces as upheld by this Court in the case of Yamashita vs. Styer: An importance incident to a conduct of war is the adoption of measure by the military command not only to repel and defeat the enemies but to seize and subject to disciplinary measure those enemies who in their attempt to thwart or impede our military effort have violated the law of war. Indeed, the power to create a military commission for the trial and punishment of war criminals is an aspect of waging war. Thus, E.O. no. 68 is valid and constitutional in conformity with the generally accepted and policies of international law which are part of our Constitution.
