WTO Dispute Settlement 1995-2012--A Statistical Analysis

Abstract

In each of the past few years, we have presented in this journal a statistical analysis of World Trade Organization (WTO) dispute settlement. This year, we continue that analysis by adding data for 2012. The statistical analysis below focuses on several different aspects of the dispute settlement system. First, we will examine the ‘complaints’. Specifically, we will look at: the number of complaints brought each year, the number of ‘matters’ those complaints comprise, which WTO Members have brought the most complaints, and which have been subject to the most complaints, the income classification of the Members involved as complainants and respondents, and the WTO agreements that have been subject to complaints. Next, we will examine the ‘decisions’ that have been made pursuant to the Dispute Settlement Understanding (DSU), that is, the panel and Appellate Body reports and the arbitration awards and decisions. In particular, we will look at the following: the number of each type of decision circulated each year, and the percentage of panel reports appealed. We will then consider separately the issue of complaints and decisions relating to ‘compliance’ under the special provisions of DSU Article 21.5. Finally, we include data on the country of origin of WTO panelists.
