The United Nations Appeals Tribunal (UNAT) is an appellate court established by the General Assembly to review appeals against judgments rendered by the United Nations Dispute Tribunal (UNDT). It also hears and passes judgment on appeals from decisions taken by the Standing Committee acting on behalf of the United Nations Joint Staff Pension Board (UNJSPB) and by those agencies and entities that have accepted jurisdiction of the UNAT (for names of the agencies and entities see Jurisdiction). UNAT is composed of seven judges, who normally review appeals in three-member panels. Their judgments are final and binding on the parties.
The UNAT is based in New York. It holds sessions in New York, Geneva or Nairobi, as required by caseload. It held its first session in Geneva in 2010.
