Isabelle Van Damme (Sidley Austin LLP) has published Treaty Interpretation by the WTO Appellate Body (Oxford Univ. Press 2009). Here's the abstract:This book analyzes how the Appellate Body uses particular principles of general international law in interpreting the WTO covered agreements. It deals equally with general international law and WTO law. The aim is to explain how the Appellate Body interprets and applies customary international law on treaty interpretation in dealing with the WTO covered agreements. The main concern is to analyze the judicial reasoning and ways of justifying judicial decision-making. In particular, it answers the question of how the Appellate Body explains its reading of WTO treaty language.
It is argued that the Appellate Body has interpreted the WTO covered agreements in a contextual and effective manner, an approach that corresponds with general international law. The character of the WTO covered agreements has, nevertheless, confronted the Appellate Body with some questions of interpretation that were until recently unexplored or neglected by other courts and tribunals. In that sense, the Appellate Body has contributed to the development of general international law on treaty interpretation, or at least to its practice.
