The UN Appeals Tribunal (UNAT) was established by the General Assembly in 2009, as part of the new UN internal justice system. As the second level appellate review tribunal within the internal justice system, UNAT reviews, within its specific jurisdiction, appeals against judgments rendered by the UN Dispute Tribunal, the Dispute Tribunal of the UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), as well as appeals of decisions taken by the Standing Committee acting on behalf of the United Nations Joint Staff Pension Board (UNJSPB), and by those organizations, agencies and entities that accepted UNAT’s jurisdiction.

UNAT usually meets in session three times a year, in spring, summer and fall sessions, to render judgments. The sessions are held in New York, Nairobi, or Geneva (at times at other locations). UNAT consists of seven judge positions. The UNAT President usually designates three judge panels to decide each case. However, under certain circumstances a case may be heard by the entire UNAT bench. UNAT judgments are final and binding on the parties.


The UNAT Registry provides substantive, technical and administrative support to the UNAT judges in the adjudication of cases and serves as records custodian of case files and materials forming the official record of a case.

The UNAT Registry, located in New York, is headed by a Registrar who reports to the Principal Registrar. The Registry is not mandated to provide legal advice to parties.
