Judgment No. 1647
The complaint is dismissed.
It follows from WHO Manual paragraph II.1.30 that "grading hinges neither on quality of performance nor on seniority. The sole criteria are the duties and responsibilities of the post. And the grade cannot change unless there is a 'significant change in [their] level'."
