The Supreme Court published a more detailed opinion in October, saying, "Constitutional safeguards for the protection of all who are charged with offense are not to be disregarded." By then, six of Royall's clients were dead. They were tried, convicted, and executed in August 1942, only days after the Supreme Court's brief announcement upholding Roosevelt's tribunals. Two were sent to prison. Royall later said he believed his defense of the Nazis was his most important work in a long and illustrious career. He was promoted to brigadier general.
