The fourth edition of the Repertory of Reports and Awards (the 'Repertory') serves first and foremost as a source of information for those interested in the field of international trade law. Initially developed as an internal research tool to assist the Appellate Body Secretariat in carrying out its duty to provide legal support to Appellate Body Members, the Repertory has become a practical tool for officials from WTO Member States, and in particular for Members (including developing-country Members) that may not have the resources to prepare a similar compendium in-house. The Repertory is also of assistance to academics, students, private practitioners and other followers of international trade law and dispute settlement.
