WTO panel

A WTO panel is the first-instance adjudicative body in the World Trade Organization's dispute settlement system, governed by the Understanding on Rules and Procedures Governing the Settlement of Disputes (DSU), annexed to the 1994 Marrakesh Agreement. When consultations between disputing members fail to resolve a complaint within 60 days, the complainant may request the Dispute Settlement Body (DSB) to establish a panel under Article 6 of the DSU.

Panels are typically composed of three individuals (Article 8), drawn from an indicative list of qualified governmental and non-governmental experts maintained by the Secretariat. Panelists serve in their individual capacity, not as state representatives, and nationals of parties to the dispute are generally excluded unless both parties agree. If the parties cannot agree on composition within 20 days, the WTO Director-General appoints the panelists.

The panel's task, under Article 11, is to make an "objective assessment" of the facts and the applicability of the covered agreements, and to issue findings that assist the DSB in making recommendations. Proceedings include written submissions, two oral hearings, and an interim review stage before the final report is circulated to all members, normally within six to nine months. Reports are adopted by the DSB by reverse (negative) consensus unless appealed to the Appellate Body.

Panels have ruled on landmark matters including EC – Hormones, US – Shrimp, EC – Bananas III, and China – Rare Earths. Since December 2019, the Appellate Body has been non-functional due to the United States blocking new appointments, leaving many panel reports in legal limbo when parties file "appeals into the void." A subset of members has responded with the Multi-Party Interim Appeal Arbitration Arrangement (MPIA) under DSU Article 25 to preserve binding appellate review pending reform.

Panels do not create binding precedent, but their reasoning is routinely cited in subsequent disputes.
