Kingdom of Spain v. Estate of Claude Cassirer

Issue: 1. Whether the Foreign Sovereign Immunities Act “expropriation exception”? permits U.S. courts to strip a foreign sovereign of its presumptive sovereign immunity simply because it owns property allegedly taken in violation of international law by another nation? 2. Whether a plaintiff relying on the FSIA’s expropriation exception must exhaust available remedies in the relevant country before invoking the jurisdiction of U.S. courts?
