Trade Dispute Settlement
How the WTO's dispute settlement system works, why the US broke it, and what comes next for trade law enforcement.
The Crown Jewel of the WTO
The WTO's dispute settlement system was once called the 'crown jewel' of the multilateral trading system. Before its creation in 1995, trade disputes were resolved through the GATT's weaker mechanism, where a single country could block a ruling. The WTO's Dispute Settlement Understanding (DSU) introduced binding adjudication: a panel of trade law experts hears the case, issues a ruling, and the losing party must comply or face authorized retaliation. An Appellate Body of seven members reviews appeals.
The system was remarkably active. Between 1995 and 2023, WTO members filed over 620 disputes. The EU, US, and China have been the most frequent users. Landmark cases shaped global trade rules: the Boeing-Airbus subsidies dispute (the longest in WTO history), the US-China rare earths case, and Brazil's successful challenge to US cotton subsidies that resulted in compensation payments to Brazilian farmers.
