The developed and developing members of the World Trade Organization (WTO) are deeply divided on the concept, scope, and beneficiaries of the special and differential treatment (SDT) provisions. The division was revealed in the Committee on Trade and Development meetings, where developed members rejected the Group of 90's proposals to strengthen and operationalize SDT provisions in WTO agreements. This article focuses on the SDT provisions in the Dispute Settlement Understanding (DSU), positing that the provisions are ineffective in upholding the WTO's development objectives. It analyses the extent to which the needs and circumstances of low-income developing countries and least-developed countries have been considered by the WTO adjudicating bodies through the application and interpretation of SDT provisions in the DSU. The article seeks to reimagine SDT provisions’ role in the DSU through secondary lawmaking and progressive treaty interpretation to ensure development is integrated into the WTO's Dispute Settlement Mechanism.
