WTO Dispute Settlement Mechanism

The WTO dispute settlement mechanism is a rules-based process through which members challenge measures that breach WTO obligations or impair negotiated trade benefits. It is governed principally by the Dispute Settlement Understanding, and administered by the Dispute Settlement Body, which consists of all WTO members.

Consultations and panel proceedings

The mechanism initially seeks a mutually agreed solution, but permits adjudication when consultations fail.

• Under Article 4 of the DSU, the complaining member requests consultations and identifies the disputed measures and legal basis of its complaint.
• If consultations do not resolve the dispute, the complainant may request a panel. A panel is generally established through reverse consensus, meaning that establishment can be blocked only by consensus against it.
• The panel objectively examines the facts and relevant covered agreements, receives submissions from parties and third parties, and issues findings on whether the challenged measure violates WTO obligations.

Review and adoption of rulings

Panel reports become binding upon the parties only after adoption by the Dispute Settlement Body.

• A panel report is adopted unless a party appeals or the Dispute Settlement Body decides by consensus not to adopt it, another application of reverse consensus.
• Under the DSU framework, appeals go to the Appellate Body and are confined to legal issues and legal interpretations in the panel report.
• Once adopted, panel and appellate findings become Dispute Settlement Body recommendations and rulings that the parties must implement.

Compliance and enforcement

The principal remedy is correction of the inconsistent measure, not retrospective damages or punishment.

• The losing member must bring its measure into conformity immediately or within a reasonable period of time where immediate compliance is impracticable.
• A disagreement about whether compliance has occurred may be examined through proceedings under Article 21.5 of the DSU.
• If compliance is not achieved, the parties may negotiate temporary compensation. Compensation is voluntary and must remain consistent with WTO agreements.
• As a last resort, the Dispute Settlement Body may authorize the complainant under Article 22 to suspend equivalent trade concessions, commonly called retaliation, until compliance or another settlement is achieved.
