In Judgment No. UNDT/2022/028, the Tribunal rejected the application in Case No. UNDT/NY/2021/023, finding that the Applicant is ineligible for boarding allowance for his child. In this case, the Applicant essentially challenges the same decision to find him ineligible for boarding allowance for his child, the issue of which was already resolved in Judgment No. UNDT/2022/028. Therefore, under the doctrine of res judicata, the Tribunal rejects the present application.
