Republic of Hungary v. Simon

Issues: (1) Whether historical commingling of assets suffices to establish that proceeds of seized property have a commercial nexus with the United States under the expropriation exception to the Foreign Sovereign Immunities Act; (2) whether a plaintiff must make out a valid claim that an exception to the FSIA applies at the pleading stage, rather than merely raising a plausible inference; and (3) whether a sovereign defendant bears the burden of producing evidence to affirmatively disprove that the proceeds of property taken in violation of international law have a commercial nexus with the United States under the expropriation exception to the FSIA.
