The present chapter concludes the work. It sums up the key findings of the study while discussing the results emerging from a comparative analysis of the three categories of disputes examined throughout the book. The chapter then revisits the central arguments put forth in the book and articulates the lessons to be learned for the study of the goals, operation, and effectiveness of the World Trade Organization (WTO) Dispute Settlement System (DSS), and of international courts more broadly. It also discusses some of the insights to be offered with respect to possible institutional changes or reforms of the WTO DSS, with a view to ensuring the system’s future effectiveness. The chapter closes with several observations that go beyond effectiveness, pertaining to the costs and unintended consequences attendant on more effective and empowered international adjudication.
