The Iran-United States Claims Tribunal has been called “the most significant arbitral body in history”; its awards, “a gold mine of information for perceptive lawyers.” In a recent international commercial arbitration, however, an arbitrator reportedly stated that decisions of the Tribunal, although on point, were not persuasive because the Tribunal, after all, involves a special type of arbitration. This arbitrator is not alone. A lecturer at the Hague Academy of International Law, speaking on international commercial arbitration, reportedly did not refer to the Tribunal’s jurisprudence because he did not find it relevant to his work for the same reason. Viewed as a gigantic experiment in international dispute resolution rather than merely a claims settlement device for this particular group of disputes, the Tribunal thus appears (at least to some) to yield decisions of unclear precedential value. Millions of dollars have been spent on its operation and hundreds of awards rendered, yet an apparently not uncommon perception is that the work of this, in some respects unique, institution is not applicable elsewhere.
