The WTO dispute settlement system is unusually strong but not necessarily unique. How the Appellate Body reads the WTO covered agreements is not a matter of WTO law, it is a technique of general international law. The Appellate Body comes to interpretation from within its function in the WTO institution as a juridical body. This book explains how the Appellate Body approaches the interpretation of the WTO covered agreements, and contributes to a more general understanding of how treaties are interpreted in practice. It is as much about general international law as it is about WTO law.
