Extract

This Essay Provides a critical assessment of the system of military justice established in Austria by the American occupation authorities. It places military justice and its function in the wider context of U.S. occupation policy as it developed from total control to increasingly milder forms of tutelage under the impact of the Cold War and increasing Austrian self-assertion. The essay is based on the hitherto largely untapped files contained in seventy-five boxes of the Legal Division of the U.S. Military Government in Austria, collected in two visits in 1990 and 1991 to the National Archives in Suitland, Maryland.

This essay is a revision of a paper presented at the annual conference of the German Studies Association in September 1991 at Los Angeles. The author thanks two anonymous referees for their suggestions, which helped to clarify the major points.

Members of the Heimwehr and the Sturmscharen who took an active and prominent part in those organizations were removable but could be retained or reinstated if their political record was other-wise satisfactory and if they were eligible to vote and to be elected to office.

Deutsch's successor, a professor of psychology at the College of William and Mary, was chief, Legal Division, from 12 June 1946 to 12 June 1947. Although a jurist by training in Austria, he had given up jurisprudence for psychology in the United States and had not kept up with legal developments in Austria. Even his German had deteriorated. He was a most unfortunate choice since neither his subordinates in the Legal Division nor the military professionals respected him. His successors were military officers again.

29 When the American forces entered their occupation zone in Vienna in August 1945, they encountered an already-ongoing Austrian judicial system and found it opportune not to impose Ordinance 200, since by and large, there was no indication of any action by the Austrian government “which would have been contrary to U.S. policy had the regime been operating under USMG directive.” Legal Division, USACA, Progress Report for week ending 1 September 1945, 2 September 1945, 260/61/319.1 L.

47 According to Austrian law, a public disorder can only exist when, through the action of the persons, an active intervention of law enforcement agencies is called for and is actually executed. The Austrian police apparently did not consider the anti-Semitic shouts an incitement to public disorder, considering them mere expressions of hostile feelings rather than a call for hostile action. For a succinct elaboration of the relevant points of Austrian law, see the petition for the review of the judgment by the defenders of the two principal accused, Dr. Franz Zamponi, Linz, and Dr. Kurt Regner, Vienna, dated 14 October 1947. I am indebted to Dr. Regner for this and other material concerning the trial.

48 The chief prosecutor was Bernard Corwin, the chief legal officer of MG Upper Austria; the chief judge was Col. Claude Billingsley, chief of G-4 in Upper Austria, perhaps a good engineer but not versed in the law.
