On October 30, 1939, a series of 153 awards in the so-called Sabotage Claims against Germany was handed down by the Mixed Claims Commission under the Agreement of August 10, 1922, between the United States and Germany. These awards were made pursuant to the decision of the Commission rendered on June 15, 1939, and the order entered the same day, which held that German sabotage agents in this country were responsible for the destruction of the Black Tom Terminal on the night of July 29,1916, and the Kingsland Plant on January 11, 1917, and that Germany was liable for the damages resulting from these destructions. After the pleadings had been filed in 1927-1928, together with considerable evidence, and after the argument in Washington in April, 1929, and the reargument at The Hague in September, 1930, the Commission withdrew to Hamburg and rendered a decision dated October 16, 1930, dismissing all of the claims as not involving German responsibility. The Commission, however, found that the German Government had authorized a general campaign of sabotage in the United States during the period of neutrality and had sent men to this country for that purpose. The efforts of the American Agent in opposition to the German Agent to obtain a reconsideration of this decision resulted in several decisions of interest to the science of international law. The limited space permits only a summary discussion of the main questions.
