Maria von Altmann, in California, has sued the Austrian Gallery (whatever that is) and the Austrian state over six Gustav Klimt paintings. The 9th U.S. Circuit Court of Appeals has held that the case can be heard in the USA if the claims are proved. The Supreme Court of the U.S.A. has announced that it will hear the appeal, in order to define when foreign governments can be sued in U.S. courts. (See report on CBS News, via Legal Reader).
