The Tribunal held that the decision to change a staff member’s reporting lines is not a reviewable administrative decision under art. 2(1)(a) of the Dispute Tribunal's Statute. The Tribunal, further, established that the contested decision did not produce direct adverse legal consequences to the Applicant’s employment contract. The Applicant continued to perform his functions at the P-4 level. The only change was that he reported to different persons. Accordingly, the application was dismissed as not receivable.
