Constitutionalization of WTO Law
Research Guide
What is Constitutionalization of WTO Law?
Constitutionalization of WTO Law theorizes the World Trade Organization's dispute settlement system as evolving into a quasi-constitutional order with judicialized norms, direct effect, and legitimacy challenges amid international law fragmentation.
Scholars debate WTO's shift from contractual trade rules to governance-like authority through Appellate Body rulings. Key works examine judicialization's impact on compliance and state sovereignty (Zangl, 2008; 114 citations). Over 10 papers from 2000-2020 analyze dimensions like remedies and norm collisions (Trachtman, 2006; 104 citations).
Why It Matters
Constitutionalization frames WTO disputes as constitutional challenges to sovereignty, influencing trade policy in US-EU cases (Zangl, 2008). It shapes legitimacy debates in investor-state arbitration reforms (Roberts, 2018). Trachtman's analysis of WTO constitutions guides institutional design for global economic governance (Trachtman, 2006). Pauwelyn documents trade system's transformation, impacting multilateral negotiations (Pauwelyn, 2005).
Key Research Challenges
Fragmentation vs Unity
Norm collisions between WTO rules and other regimes challenge systemic coherence (Kreuder-Sonnen and Zürn, 2020; 106 citations). Interface conflicts require management strategies beyond traditional adjudication. Scholars debate unity through constitutional analogies (Trachtman, 2006).
Judicialization Legitimacy
WTO's legalized dispute settlement raises democratic deficit concerns (Zangl, 2008; 114 citations). Appellate Body expansions test member state consent. Compliance paradoxes persist despite judicial gains (Mavroidis, 2000; 262 citations).
Remedies Effectiveness
Dispute settlement remedies face enforcement gaps in non-compliant states (Mavroidis, 2000). Economic vs legal views diverge on system efficacy. Hathaway's outcasting theory explains international enforcement limits (Hathaway and Shapiro, 2025; 104 citations).
