UNDT/2010/022, Fagundes
The mandate of UNDT is confined to the review of administrative decisions. Although the definition of this term may be disputed, it is beyond question that administrative decisions must by essence be taken by the Administration. Since the decisions of former UNAT are judicial decisions, they cannot be contested before UNDT. The provisions on transitional measures apply to pending UNAT cases only. They do not include the power to revise UNAT judgements. Cases closed by judgments of former UNAT are res iudicata.
