Ministries Trial
After his arrest in May 1945, Berger remained in Allied custody pending a trial before a US military tribunal for various war crimes. He was initially to be a defendant in the proposed "Prisoners of War" Trial, but was eventually included in what became known as the Ministries Trial of the subsequent Nuremberg trials. The final indictment against Berger and his co-defendants was lodged on 18 November 1947; the trial commenced on 6 January 1948, before Judges William C. Christianson (presiding), Maguire and Leon W. Powers, and ended on 13 April 1949.
