The UNDT found that the application was not receivable as the Applicant had failed to take the mandatory first step of requesting management evaluation of the contested decision. However, it observed that while failure to request management evaluation denies the Applicant access to the Tribunal’s jurisdiction at present, the Applicant was never formally notified in writing of the administrative decision or the reasons therefore. Furthermore, the Tribunal noted that the situation in this case arose through an alleged mistake of the Administration and through no fault of the Applicant.
