The Iran-United States Claims Tribunal's recent decision in Sabet and The Islamic Republic of Iran sheds new light on difficult issues concerning the dual nationality of minors. In particular, the case was the first in which the Tribunal determined minor dual national claimants to have a dominant and effective nationality different from that of either of their parents. Further, the Tribunal broke new ground in its analysis of 'the caveat,' an equitable doctrine that can bar the claims of dual nationals. This article applauds the Tribunal's advances in its caveat jurisprudence and develops a new approach that would further those advances.
