The erosion of multilateralism in international trade through the ambiguity and abuse of the national security exception under article XXI of the GA TT, 1994

Abstract

The multilateral trading system faces a significant crisis of credibility rooted in the national security exception under Article XXI of the General Agreement on Tariffs and Trade (GATT) 1994. Although originally intended as a narrow safeguard for genuine security concerns in exceptional circumstances, this provision has increasingly served as a tool for economic protectionism and geopolitical leverage. The ambiguous wording of Article XXI worsens the erosion of multilateralism, specifically the phrase ‘which it considers necessary’ which has led to ‘self-judging’ interpretations by Member States. This ambiguity allows states to circumvent obligations and weaponise trade restrictions under the guise of national security. Such abuse threatens the predictability, legitimacy, and authority of the World Trade Organization (WTO) and creates loopholes for opportunistic behavior that undermine the dispute settlement mechanism. This study determines the extent to which the ambiguity and abuse of the national security exception contribute to the erosion of multilateralism. It further identifies reforms capable of balancing genuine security concerns with WTO credibility. The study employs a qualitative research methodology based on a comprehensive desktop literature review. It concludes that the unchecked invocation of security exceptions creates asymmetries in enforcement and encourages the fragmentation of the global trading system. To prevent the further erosion of the rules-based order, this study recommends reasserting legal discipline without eroding sovereignty. Specific recommendations include clarifying the meaning of ‘essential security interests’ and ‘emergency in international relations’ through authoritative interpretive acts, embedding the principles of good faith and necessity, and establishing procedural safeguards such as mandatory notification and standing peer- review bodies. These reforms aim to transform Article XXI from a loophole for unilateralism into a principled safeguard that preserves legitimate security autonomy.
