In 1947 Justice Brand was appointed by the War Department to the War Crimes Tribunal to be convened in Germany after World War II. There he was one of four judges of Nazi War Crimes at the Judges' Trial, the third in a set of twelve trials collectively known as the Subsequent Nuremberg Trials. The trial began in March 1947 with Brand as a member of a three-person Military Tribunal, but on June 19, 1947 he became the Presiding Judge when Carrington T. Marshall resigned for health reasons.
