The United Nations Administrative Tribunal is a specialised jurisdiction established by Resolution 351 A (IV) of the General Assembly on 24 November 1949. It comprises seven members of different nationalities, appointed by the General Assembly for a term of four years, renewable once. The Tribunal is competent to hear and pass judgment upon applications alleging non-observance of contracts or terms of employment of UN staff members as well as applications alleging non-observance of the regulations and rules of the Joint Staff Pension Fund.

During its 62nd Session, the General Assembly decided, in its Resolution 62/228, to revise the mechanisms for the administration of justice and establish two levels of jurisdiction: the United Nations Dispute Tribunal; as a first level instance, and the United Nations Appeal Tribunal. This reform was formalised in Resolution 63/253, the new judges were elected in the first half of 2009 and the new institutions started work on 1 July 2009.
