UNAT considered an appeal by the Secretary-General. UNAT held that the counsel of the Secretary-General had not been notified of the hearing date due to a technical error in the e-mail communication, which prejudiced seriously the Secretary-General’s defence. UNAT held, therefore, that the UNDT judgment should be set aside, and the matter retried afresh. UNAT upheld the appeal and vacated the UNDT judgment. The case was remanded to UNDT to be heard afresh.
