UNAT held that UNDT did not err on a question of law in deciding that the Appellant had to establish that, without the errors committed in the review of her professional career, she would have had a real chance of being promoted. UNAT held that the Appellant had failed to establish that UNDT erred on a question of fact, resulting in a manifestly unreasonable decision, in deciding that she had failed to demonstrate that the few material errors in her factsheet deprived her of the chance to be promoted. UNAT dismissed the appeal and affirmed the UNDT judgment.
