This case study illustrates the manner in which Thailand raised the issue and challenged the EC tariff within the framework of the Dispute Settlement Understanding (DSU) provided for in the WTO Agreement. There are three major stages to the DSU: consultation between the concerned parties, adjudication by Panels and, if necessary, the Appellate Body, and implementation of the ruling. However, it is not always necessary for every case to follow this trajectory and to be taken to Panels. In fact, the preferred path is for members to settle the dispute between themselves, through consultations.(2)
