In considering the appeal brought forth by the Appellant, UNAT preliminarily held that the UNRWA JAB erred in finding that the appeal was not receivable due to late filing; UNAT held that it was evident the JAB appeal was filed on time. With regard to the substance of the appeal, UNAT held that it was within UNRWA’s power and discretion to refuse the Appellant’s reinstatement since it had already filled his position. UNAT affirmed UNRWA’s position that there was no error in refusing the Appellant’s reinstatement and dismissed the appeal.
