The Development of World Trade Organization Law: Examining Change in International Law examines the development of the law of the WTO through an analysis of competing global actors, norms, and institutions that have influence over it. Taking a different approach to social-scientific or traditional legal models, this book argues that such globalized actors are the driving force behind the development of WTO law. Identifying causal language as key to understanding this development, the volume examines three different causal influences: instrumental, systemic, and constitutive. It applies this causal methodology to three key areas of WTO law- safeguard measures, sanitary and phytosanitary measures, and subsidies. The volume provides detailed explanations of why the law has developed as it has and offers insights into the future functioning of the WTO system. -- publisher's description
