Precedent in the WTO: Retrospective Reflections for a Prospective Dispute Settlement Mechanism

Several factors triggered the legitimacy crisis which paralysed the WTO Appellate Body in December 2019. This article focuses on one of them: the criticism expressed by the United States that the 'Appellate Body claims its reports are entitled to be treated as precedent'. This work describes the origins of the problem and examines the issue of the precedential value of adopted reports within the WTO dispute settlement. It argues that the problem cannot be addressed through textual attempts to better define the value of precedent, as some have suggested, but can be alleviated through the practice of adjudicators. Moreover, it argues that the criticisms regarding the precedential value of past reports is due to the inherent hierarchy ensuing from the existence of an appeals organ. Therefore, the demise of the Appellate Body may weaken the precedential value of past adopted reports.
