In pursuit of the objectives set forth in the United Nations Charter, the Organization, through its personnel, implements actions deemed optimal by the majority. In this context, staff members, as the most significant asset of the Organization, are required to undergo changes in order to enhance service delivery. It is therefore possible that, as a consequence of such changes, certain rights of employees may be infringed, necessitating the restoration of those rights through a specialized mechanism. During the period between the decision of the United Nations General Assembly in 1949 and the establishment of the United Nations Administrative Tribunal, up to the present time, the system has experienced a trajectory marked by significant developments and challenges. Although the General Assembly, through Resolution 63/253 adopted in 2008, established the United Nations Dispute Tribunal and the United Nations Appeals Tribunal as replacements for the former Administrative Tribunal, the fundamental objective has remained the attainment of justice in the resolution of internal administrative disputes.
