Staff rule 12/3(b) – exception to staff rules: The Tribunal held that under the unique circumstances of this case, that is, the requests from MINURSO recognizing the Applicant’s suitability for the post and the Mission’s dire operational needs, for the Respondent to have properly complied with staff rule 12.3(b), the Applicant’s existing educational qualifications along with his professional qualifications and language skills should have been considered regardless of whether or not they were equivalent to a high school diploma.
