United States—Measures Concerning the Importation, Marketing and Sale of Tuna and Tuna Products

Abstract

In a Mexican challenge against U.S. criteria for labeling tuna products as “dolphin-safe,” the Appellate Body of the World Trade Organization (WTO), on May 16, 2012, held against the United States while reversing various findings of the panel. The case was one of three WTO Appellate Body decisions issued in 2012 that interpreted and applied the key substantive provisions of the Agreement on Technical Barriers to Trade (TBT Agreement or TBT) for the first time. Systemically, the decision is important for its interpretation of the TBT Agreement’s substantive obligations, the types of labeling that fall within the scope of the Agreement, the legitimacy of labeling based on foreign process and production methods (PPMs), and the relation of other international law to WTO law.
