This article surveys some emerging issues in the jurisprudence of the new United Nations Appeals Tribunal.  Through an analysis of both procedural and substantive questions that the tribunal has faced in its first year (for example specific performance, production of documents, and whistleblower protection), the article offers an assessment of the implementation of the reform of the formal justice system of the United Nations. The developing jurisprudence of the tribunal will be an important indicator of the success or failure of the implementation of an independent system of justice within the United Nations.
