The petition for writ of certiorari is granted. We are of the view that under Silesian-American Corp. v. Markham, 156 F.2d 793, 796, affirmed, 332 U.S. 469, a state court is without power to review the discretion exercised by the Attorney General of the United States under federal law. The judgment is therefore reversed and the cause remanded to the Appellate Court of Indiana. On remand the Indiana courts are of course free to consider other questions presented by this record in light of General License 94, 12 Fed. Reg. 1457, as it may have affected the definition of "national" in Executive Order 9095, 7 Fed. Reg. 1971, as amended, and Executive Order 8389, 5 Fed. Reg. 1400. See GMO. Niehaus & Co. v. United States, 139 Ct. Cl. 605, 153 F.Supp. 428.
