UNAT is competent to hear and pass judgment on appeals from judgments of the UNDT and the Dispute Tribunal of the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), decisions taken by the Standing Committee acting on behalf of the UNJSPB and decisions taken by the heads of those agencies and entities that have accepted jurisdiction of the UNAT, which currently include the International Civil Aviation Organization (ICAO), the International Court of Justice (ICJ), the International Maritime Organization (IMO), the International Seabed Authority (ISA) and the International Tribunal for the Law of the Sea (ITLOS).
UNAT may review an UNDT judgment under appeal only on limited grounds. As an appellant you must allege that UNDT has:
- i) exceeded its jurisdiction or competence;
- ii) failed to exercise jurisdiction vested in it;
- iii) erred on a question of law;
- iv) committed an error of procedure, such as to affect the decision of the case; or
- v) erred on a question of fact, resulting in a manifestly unreasonable decision.
Appeals may be filed as follows:
- i) A judgment rendered by the UNDT and the Dispute Tribunal of UNRWA may be appealed by either party;
- ii) A decision of the Standing Committee acting on behalf of the UNJSPB may be appealed by a UNJSPF participant;
- iii) An administrative decision made by the head of a specialized agency or entity that has accepted the jurisdiction of UNAT may be appealed by a current or former staff member of the agency or entity.
