State of Confusion: The Doctrine of “Clean Hands” In Investment Arbitration after the Yukos Award

Résumé (dans la langue de publication) :

This article examines the controversial question of the clean hands doctrine in investment arbitration and how tribunals have analyzed this concept. Many tribunals have concluded that they lacked jurisdiction over a claim (or that it was inadmissible) because an investor had made its investment in violation of the host State’s laws. This article argues that this legality requirement is a manifestation of the clean hands doctrine. The main focus of the article is a critical review of the recent Yukos award. It assesses the Tribunal’s conclusion that the doctrine should not be considered as a general principle of law and its rejection of the application of the doctrine to violations committed by an investor during the post-establishment phase of its investment. The article argues that a number of investment tribunals have in fact already applied the clean hands doctrine in their awards to bar the admissibility of claims.
