The Iran–US Claims Tribunal (IUSCT) was created as part of the negotiated settlement recorded in two complementary declarations known as the Algiers Declarations, and was a response to the severe crisis in relations between the two States between 1979 and 1981.
This crisis was precipitated by, among others, the seizure of the United States Embassy in Tehran and its diplomatic and consular staff and actions taken by the United States in response thereto.
The IUSCT has jurisdiction over a specific set of disputes relating to a specific time period and with a specific configuration of parties as between Iran, the United States, and their respective nationals. It will cease to exist once these disputes have been resolved. Insofar as the claims of nationals against the two States are concerned, these disputes concerned debts, contracts, expropriations, and “other measures affecting property rights”.
Most of the claims of nationals against one or the other State were resolved by the mid1990s. Since then, the work of the Tribunal has been focused on resolving the remaining disputes between the two States which concern contractual arrangements between them for the purchase and sale of goods and services, and the interpretation or performance of their respective obligations under the Algiers Declarations. In its more than 40-year history, the IUSCT’s jurisprudence has had a significant influence on various aspects of international law, including the law of State responsibility as it has been applied by investor-State arbitral tribunals.
For example, certain IUSCT awards concerning expropriation and “other measures affecting property rights” are considered to be foundational statements of the modern international law of expropriation, in its direct and indirect forms. Concerning attribution, the IUSCT has closely considered the link between the actions of persons or entities distinct from the State, and the State, to determine whether the State should be liable for those acts. On nationality, the IUSCT has also produced substantial case law regarding the nationality of individual claimants, especially dual nationals, which has influenced inter alia the treatment of this issue by investor-State arbitral tribunals.
The panel will consider whether the Tribunal’s jurisprudence concerning these issues remains influential today and the relevance of the similarities and differences between the jurisdictional bases for decisions of the IUSCT and investor-State arbitral tribunals.
This panel will discuss the substantive contribution to the development of international law made by the IUSCT and will reflect more broadly upon the lessons learned from its experience concerning the peaceful settlement of disputes between States.
