The UN has an internal justice system to resolve staff-management disputes because the organization has immunity from local jurisdiction and cannot be sued in a national court.
The UN Administrative Tribunal functioned from 1950-2009. It was replaced in 2009 by the new system, composed of two tribunals: the UN Dispute Tribunal and the UN Appeals Tribunal. The General Assembly adopted the new system of administration of justice in resolution 63/253 of 24 December 2008.
The UN Dispute Tribunal (UNDT) is the body to which staff members can formally dispute an administrative decision taken against them. When resolution through informal means cannot be arrived at, and when the result of the management evaluation is not to the satisfaction of the staff member, an application can be made to the UN Dispute Tribunal, as a court of first instance.
The UN Appeals Tribunal reviews appeals against decisions made by the UN Dispute Tribunal. Both staff and the administration can appeal UNDT decisions to the Appeals Tribunal.
The Statutes of both tribunals are annexed to General Assembly resolution 63/253.
The Rules of Procedure for both tribunals are found in General Assembly resolution 64/119 of 16 December 2009.
The text of judgements and orders of both tribunals are available on their websites.
Judgements of the UNDT are identified by the year of the judgement, the judgement number and the individual party's name.
