 Schoenberg showed that three of the conditions pertinent to the case were that Altmann's property had been taken in violation of international law; the property was owned by the state in question, or one of its agencies; and that the property had been used on a commercial basis in the US.Over four years of litigation followed as to whether the case could be brought against a sovereign state before it was brought before the Supreme Court in "Republic of Austria v. Altmann".In June 2004 the Supreme Court determined that the paintings had been stolen and that Austria was not immune from a claim from Altmann; the court made no comment on the current ownership of the paintings.
