The trial was held in Assembly Hall #1 on the fifth floor of the Department of Justice building in Washington D.C. on 8 July 1942.[22] Lawyers for the accused, who included Lauson Stone and Kenneth Royall, attempted to have the case tried in a civilian court but were rebuffed by the United States Supreme Court in Ex parte Quirin, 317 U.S. 1 (1942), a case that was later cited as a precedent for the trial by military commission of any unlawful combatant against the United States.
