UNAT held, noting that the Appellant relied on the UNDT Rosca jurisprudence (judgment No. UNDT/2009/052) in her request for UNDT to waive the time limits for management evaluation, that the plain language of Article 8. 3 of the UNDT Statute could not be disregarded. UNAT approved judgment No. UNDT/2009/051 as the law on this issue and disapproved the interpretation of UNDT in Rosca. UNAT dismissed the appeal and affirmed the UNDT judgment.
