The staff member appealed on the ground that UNDT had made errors of fact in the judgment. UNAT recalled that in order to overturn a finding of fact, UNAT must be satisfied that the finding is not supported by the evidence or that it is unreasonable. Some degree of deference should be given to the factual findings by UNDT as the court of first instance, particularly where oral evidence is heard. UNAT dismissed the appeal finding that there were no grounds for overturning the UNDT’s findings of fact and that no other reversible errors were made.
