In the days after the military order on November 13, 2001, to try suspected terrorists, and particularly those detained at Guantanamo Bay, before military commissions, "Ex parte Quirin" was frequently cited as the legal basis for the order. Upon the capture of the "Quirin" saboteurs, President Roosevelt had issued an executive order, upon which the order issued by President Bush was putatively modeled; this authorized military commissions to try the captives for, among other offenses, violations of the laws of war, providing the enemy with intelligence, and spying.
