327 U.S. 1, 66 S. Ct. 340, 90 L. Ed. 499 (1946)
Tomoyuki Yamashita served as Commanding General of the Fourteenth Army Group of the Imperial Japanese Army in the Philippine Islands.1 On September 3, 1945, he surrendered to United States Army Forces in Baguio and became a prisoner of war.2 On September 25, 1945, Lieutenant General Wilhelm D. Styer served him with a charge alleging violation of the law of war.3
On October 8, 1945, Yamashita pleaded not guilty before a military commission of five Army officers appointed by General Styer.4 Six Army officers served as defense counsel.5 He was also served on that day with a bill of particulars alleging 64 crimes by troops under his command.6 A supplemental bill alleging 59 more crimes by his troops was filed on October 29.7 The commission heard two hundred eighty-six witnesses who gave over three thousand pages of testimony.8 On December 7, 1945, the commission found Yamashita guilty and sentenced him to death by hanging.9
Yamashita filed petitions for writs of habeas corpus and prohibition in the Supreme Court of the Commonwealth of the Philippines, which denied relief after hearing argument.10 He also sought leave to file similar petitions directly in the United States Supreme Court.11 The United States Supreme Court granted certiorari to review the Philippine court's order and consolidated the applications for argument.12
The charge alleged that between October 9, 1944, and September 2, 1945, Yamashita unlawfully disregarded and failed to discharge his duty as commander to control the operations of members of his command, permitting them to commit brutal atrocities against civilians and prisoners of war, including the massacre of more than twenty-five thousand unarmed noncombatant civilians in Batangas Province.13 During the trial the commission admitted depositions, affidavits, hearsay, and opinion evidence over defense objection.14
Whether the military commission was lawfully created and had authority to try petitioner for violations of the law of war after the cessation of hostilities between the armed forces of the United States and Japan?15
Congress in the Articles of War recognized military commissions as appropriate tribunals for trial of offenses against the law of war.16 The war power authorizing such commissions continues from declaration of war until peace is proclaimed by treaty or political act, allowing trial of violations committed before cessation of hostilities.17
Yes. General Styer, as a commander competent to appoint general courts-martial, issued the order creating the commission pursuant to directives from the Joint Chiefs of Staff and General MacArthur.18 This conformed with presidential proclamation and the Potsdam Declaration accepted by Japan.19 The commission was convened after Yamashita's surrender on September 3, 1945.
The charge was served on September 25, 1945, with trial concluding December 7, 1945, before any proclamation of peace. The authority to create the commission and direct trial by military order therefore continued after cessation of hostilities.20 The war power carries the inherent authority to guard against renewal of conflict and remedy evils produced by military operations.21 No treaty or proclamation had ended the state of war.22
The military commission was lawfully created and possessed authority to try the petitioner.23

Justice Rutledge concluded that the commission was invalidly constituted because the directive under which it operated conflicted with Articles 25 and 38 of the Articles of War.24 He reasoned that those Articles apply to all military commissions without exception.25 Congress intended uniform procedural protections for every form of military tribunal.26
The broad reception of unverified evidence under the directive therefore deprived the commission of jurisdiction from the outset.27 Rutledge emphasized that the commission's power to receive any evidence it deemed helpful, including multiple hearsay and unauthenticated documents, violated the statutory scheme Congress had enacted for military tribunals. This structural defect meant the commission never acquired lawful authority to proceed.28
Whether the charge preferred against petitioner stated a violation of the law of war?29
The law of war imposes on an army commander an affirmative duty to take appropriate measures within his power to control troops under his command and prevent violations such as atrocities against civilians and prisoners of war.30 Breach of that duty by permitting such acts constitutes a violation triable by military commission.31
Yes. The charge alleged that between October 9, 1944, and September 2, 1945, Yamashita unlawfully disregarded and failed to discharge his duty as commander to control the operations of members of his command, permitting them to commit brutal atrocities including the massacre of more than twenty-five thousand unarmed civilians in Batangas Province.32 The bills of particulars specified widespread acts of violence, cruelty, homicide, pillage, and destruction committed by forces under his command.33 The Hague Conventions and Geneva Red Cross Convention recognize the commander's duty to ensure public order and protect prisoners and civilians.34
The charge adequately alleged breach of that duty even though it did not claim personal commission or direct ordering of the acts.35
The charge stated a violation of the law of war.36

Justice Murphy dissented on the ground that the charge failed to state a recognized violation of the laws of war.37 He emphasized that the allegations amounted only to a claim of inefficiency in controlling troops under overwhelming attack.38 International law imposes no such liability on a defeated commander for the disorganization created by the victor.39
The indictment permitted the commission to define the crime according to its own biased view rather than established precedent.40 Murphy stressed that no historical or treaty authority supported holding a commander criminally responsible solely for failing to prevent atrocities amid the chaos of his own army's destruction.41 The charge therefore violated fundamental principles of individual culpability.42
Whether the commission lacked authority and jurisdiction because its governing order permitted admission of depositions, affidavits, hearsay, and opinion evidence in violation of the 25th and 38th Articles of War, the Geneva Convention, and the due process clause of the Fifth Amendment?43
Articles 25 and 38 of the Articles of War and the procedural protections of the Geneva Convention apply only to persons subject to the Articles or to offenses committed while a prisoner of war.44 Enemy combatants tried by military commission for violations of the law of war are governed by the common law of war, under which the commission's rulings on evidence are not subject to judicial review.45
No. Yamashita, as an enemy combatant, was not a person made subject to the Articles of War by Article 2, and the commission was convened pursuant to the common law of war rather than the Articles themselves.46 Article 63 of the Geneva Convention likewise applies only to judicial proceedings for offenses committed while a prisoner of war, not to violations committed while a combatant.47 The commission's admission of depositions, affidavits, hearsay, and opinion evidence therefore did not violate any applicable statute, treaty, or constitutional command.48 Its evidentiary rulings are reviewable only by military authorities.49
The commission did not lack authority or jurisdiction on evidentiary grounds.50

Justice Rutledge maintained that Articles 25 and 38 applied to the proceeding and that the directive's authorization of unrestricted evidence directly conflicted with those Articles.51 He further concluded that the wholesale reception of ex parte affidavits, multiple hearsay, and untested conclusions deprived the petitioner of any fair opportunity to test the evidence or prepare a defense, thereby violating the Fifth Amendment's guarantee of due process.52
These practices converted the trial into an ex parte investigation rather than an adversarial proceeding.53
Whether the commission lacked authority and jurisdiction because of the failure to give advance notice of the trial to the protecting power as required by Article 60 of the Geneva Convention?54
Article 60 of the Geneva Convention, requiring advance notice to the protecting power, applies only to judicial proceedings directed against a prisoner of war for offenses committed while in captivity and does not govern trials for violations of the law of war committed while a combatant.55
No. The notice requirement of Article 60 appears in the section of the Convention dealing with penalties applicable to prisoners of war for conduct during captivity.5657 Yamashita was tried for offenses committed while commanding Japanese forces before his surrender, not for acts committed as a prisoner of war.58 The failure to notify the protecting power therefore did not deprive the commission of authority or jurisdiction.59
The commission did not lack authority or jurisdiction for failure to give notice under Article 60.60
