This volume, containing analyses of decisions rendered by the adjudicating bodies of the World Trade Organization in 2004 and 2005, is The American Law Institute's most recent contribution in its continuing examination of the developing law of world trade. As with our previously published volumes analyzing decisions rendered from 2001 through 2003, each study is the joint work of a lawyer and an economist, and each study has been subjected to additional review and analysis by the other contributors and by an international group of experts at an invitational conference in Geneva in March 2007. The studies are the work of the individual authors and not of The American Law Institute.

With five years of WTO case law studies now to our credit, we have begun the second phase of our world trade work, seeking to draft general principles of world trade law based on that developing body of case law. The Chief Reporters for this phase are Henrik Horn of Stockholm University and Petros Mavroidis of the University of Neuchâtel and of Columbia University School of Law. We also hope to continue our reporting and analysis of individual WTO decisions.

We are grateful to the economists and lawyers who contributed the studies in this volume and to those who reviewed and constructively criticized their earlier drafts. We also express our appreciation to the Jan Wallander and Tom Hedelius Foundation and the Milton and Miriam Handler Foundation for their continued and generous financial support of this endeavor.
