This article focuses on the World Trade Organization’s (WTO) Dispute Settlement Body (DSB) – the diplomatic body, consisting of representatives of WTO members, that administers the dispute settlement system. Focusing on the WTO, the article provides one perspective on the relationship between international tribunals and the political bodies that oversee the governance of such tribunals. Specifically, I argue that the DSB operates as an important ‘voice’ mechanism, which enables members to provide regular feedback to WTO adjudicators, and helps sustain the internal legitimacy of WTO adjudication. However, the DSB can also be used in ways that undermine judicial independence. In short, the DSB is a key site where the tension plays out between WTO adjudicators’ independence from members, and control by, and accountability to, members. The episodes examined in detail to develop this argument are the crisis of a generation ago over amicus curiae briefs, and the ongoing crisis over Appellate Body appointments.
