The Iran-United States Claims Tribunal is arguably the most significant arbitral institution of the twentieth century. Although the completion of its last few cases could take a long time, the Tribunal's impressive work must be made available now as a guide to the resolution of ongoing disputes and for future tribunals. The Tribunal has, by this point, disposed of well over 98 percent of its caseload. Little more remains for its participants to learn, but the Tribunal shows no signs of fading away. Both of the two States Parties, for different reasons, see greater advantage in the Tribunal's prolongation than in its elimination. The authors have succeeded in dealing with all of the most deserving Tribunal subjects. Moreover, their intimate involvement in and knowledge of the Tribunal ensure that their book is a fascinating, important, and indispensable contribution to the literature of International Law. This is a definitive book on a monumental event in the law and in history at the close of a century. "The Iran-United States Claims Tribunal" was awarded the ASIL Certificate of Merit.
