UNAT held that the Appellant failed to explain how UNDT exceeded or failed to exercise its jurisdiction or competence, erred on a question of law or procedure, or erred on a question of fact, resulting in a manifestly unreasonable decision. UNAT recalled that the UNDT Statute precluded UNDT from suspending or waiving the deadlines for management evaluation. UNAT held that UNDT was therefore correct in concluding that the application was not receivable and to reject it on that basis. UNAT dismissed the appeal and upheld the UNDT Judgment.
