“(1) The costs of and incidental to — (a) all proceedings in the First-tier Tribunal, and (b) all proceedings in the Upper Tribunal, shall be in the discretion of the Tribunal in which the proceedings take place. (2) The relevant Tribunal shall have full power to determine by whom and to what extent the costs are to be paid. (3) Subsections (1) and (2) have effect subject to Tribunal Procedure Rules.”
“10. On one view, there is no appeal before the Upper Tribunal until one of two events occurs. The first is the lodging with the Upper Tribunal of notice of appeal by an appellant who has been granted permission to appeal by the Firsttier Tribunal. The second is when an appellant, refused permission by the First-tier Tribunal, has secured it in the Upper Tribunal; as rule 22(2)(b) indicates, unless there is a direction otherwise, the application for permission stands as the notice of appeal. On this, narrower, view the Upper Tribunal has the jurisdiction to make a costs direction in respect of the entire period from lodging of the notice of appeal in the first case, but only from the grant of permission in the second since, until that moment, there is no appeal and, correspondingly, no “proceedings … on appeal”
