Petros C. Mavroidis - Exception Clauses in International Trade Law

·31 min·3 clips

A 1989 trade court stunned the world by ruling a country couldn't protect dolphins unless it had a global agreement.

The episode is a solo lecture by Professor Petros Mavroidis on exception clauses in international trade law under the World Trade Organization. He structures the talk into four parts: defining exceptions, discussing their rationale and architecture, examining case law evolution, and explaining new generation agreements. Mavroidis distinguishes exemptions as limits of a contract from exceptions as conditional exits from obligations. He selects Article 20 of GATT for analysis because it is the first and most influential exceptions provision, modeling others like Article 14 of the services agreement. The rationale for exceptions stems from the GATT's focus on tariffs and the need for governments to address social costs like environmental damage or child labor, which consumers might ignore. The architecture requires measures to be necessary and non-discriminatory. The case law discussion centers on two key disputes: the 1989 tuna-dolphin case, where a GATT panel controversially ruled unilateral environmental protection illegal, and the later shrimp-turtle case, which reversed that precedent by allowing unilateral measures if they meet Article 20's tests. Mavroidis explains that WTO judges can only assess the means of achieving an objective, not the objective itself. He notes the shift post-1995, where international standards from bodies like ISO become reference points, and governments can regulate freely unless complainants prove measures are unnecessary or discriminatory. The lecture emphasizes regulatory diversity among WTO's 166 members and the evolution from the 1948 GATT to modern agreements that better capture the regulatory state's role in providing public goods like health and environmental protection.
