UNAT held that it could find no fault with the UNDT’s conclusion that the application was not receivable ratione materiae, which accorded with UNAT’s jurisprudence. UNAT held that, since that ground was sufficient to affirm the UNDT judgment and to dismiss the appeal, there was no need for it to determine whether the application before UNDT challenged a specific implied administrative decision on the part of UNICEF or whether the Appellant was merely making general complaints about UNICEF’s failure to protect him. UNAT dismissed the appeal and affirmed the UNDT judgment.
