“Jurisdiction to strike out 13. The first question raised by the appeal is whether the First-tier Tribunal has power under its rules to make an order striking out some of the grounds of appeal as an abuse of process even assuming that issue estoppel or abuse of process has any application in relation to a tax appeal. It is common ground that the First-tier Tribunal is a statutory tribunal with no inherent jurisdiction. It exists to perform the functions conferred on it by theTribunals, Courts and Enforcement Act 2007 (“TCEA 2007”) and other statutes: see TCEA 2007 s.3(1). Its powers must be found in TCEA 2007 and theTribunal Procedure (First-tier Tribunal) (Tax Chamber) Rules 2009 (“the Rules”) made under the power conferred by s.22. 14. Section 22 provides for the making of rules by the Tribunal Procedure Committee. Section 22(4) provides: “(4) Power to make Tribunal Procedure Rules is to be exercised with a view to securing— Judgment Approved by the court for handing down. Shiner & Anor v HMRC (a) that, in proceedings before the First-tier Tribunal and Upper Tribunal, justice is done, (b) that the tribunal system is accessible and fair, (c) that proceedings before the First-tier Tribunal or Upper Tribunal are handled quickly and efficiently, (d) that the rules are both simple and simply expressed, and (e) that the rules where appropriate confer on members of the First-tier Tribunal, or Upper Tribunal, responsibility for ensuring that proceedings before the tribunal are handled quickly and efficiently.” 15. So far as material, the Rules now in force provide: “2. -(1) The overriding objective of these Rules is to enable the Tribunal to deal with cases fairly and justly. (2) Dealing with a case fairly and justly includes— (a) dealing with the case in ways which are proportionate to the importance of the case, the complexity of the issues, the anticipated costs and the resources of the parties. (b) avoiding unnecessary formality and seeking flexibility in the proceedings. (c) ensuring, so far as practicable, that the parties are able to participate fully in the proceedings. (d) using any special expertise of the Tribunal effectively; and (e) avoiding delay, so far as compatible with proper consideration of the issues. (3) The Tribunal must seek to give effect to the overriding objective when it— (a) exercises any power under these Rules; or (b) interprets any rule or practice direction. (4) Parties must— (a) help the Tribunal to further the overriding objective; and (b) co-operate with the Tribunal generally. ….. 5-(1) Subject to the provisions of the 2007 Act and any other enactment, the Tribunal may regulate its own procedure. (2) The Tribunal may give a direction in relation to the conduct or disposal of proceedings at any time, including a direction amending, suspending or setting aside an earlier direction. ….. 8-(1) The proceedings, or the appropriate part of them, will automatically be struck out if the appellant has failed to comply with a direction that stated that failure by a party to comply with the direction would lead to the striking out of the proceedings or that part of them. (2) The Tribunal must strike out the whole or a part of the proceedings if the Tribunal— (a) does not have jurisdiction in relation to proceedings or that part of them; and (b) does not exercise its power under rule 5(3)(k)(i) (transfer to another court or tribunal) in relation to the proceedings or that part of them. (3) The Tribunal may strike out the whole or a part of the proceedings if— (a) the appellant has failed to comply with a direction which stated that failure by the appellant to comply with the direction could lead to the striking out of the proceedings or part of them. (b) the appellant has failed to co-operate with the Tribunal to such an extent that the Tribunal cannot deal with the proceedings fairly and justly; or (c) the Tribunal considers there is no reasonable prospect of the appellant's case, or part of it, succeeding. ….. (7) This rule applies to a respondent as it applies to an appellant except that— (a) a reference to the striking out of the proceedings must be read as a reference to the barring of the respondent from taking further part in proceedings; and (b) a reference to an application for the reinstatement of proceedings which have been struck out must be read as a reference to an application for the lifting of the bar on the respondent taking further part in the proceedings.” 16. Mr McDonnell submits that although it may be possible to imply a power to strike out as part of the Rules, the circumstances in which that is possible are very limited. It is necessary to show that the implied power can be treated as part of the tribunal’s function to regulate its own procedure in order to carry out its statutory objective: see R (on the application of V) v Asylum and Immigration Tribunal[2009] EWHC 1902 (Admin) at [27]. Tribunals do not have an open-ended power to regulate their own procedure. 17. Because Rule 8(3) gives the First-tier Tribunal an express power to strike out part of the proceedings on specified grounds, there is, Mr McDonnell says, no room for any further implied power to strike out on other more general grounds. This is reinforced by a consideration of the function of the First-tier Tribunal which is to determine statutory tax appeals and to reach a conclusion on the correct amount of tax payable. Once an appeal is made under s.31 TMA 1970 the First-tier Tribunal must determine it either by upholding the assessment or by reducing or increasing it: see TMA 1970 s.50. It has, he says, a duty to determine the tax payable which differentiates tax appeals from ordinary civil litigation between private parties. 18. To strike out part of an appeal is also, Mr McDonnell says, a drastic step because it deprives the taxpayer of the opportunity of raising his arguments against a background of all the relevant facts. Unless the circumstances are exceptional, it carries with it the risk of denying the taxpayer a fair hearing. It is therefore a power which (if it exists) should only be exercisable in very limited circumstances. 19. The need to exercise caution in relation to any power to strike out proceedings prior to a full hearing is obvious. But it is a consideration which goes to the exercise of the power rather than to whether such a power exists. The Upper Tribunal in its decision at [55] did not take Mr McDonnell to have submitted that there was no power to strike out for abuse of process but in any event, in my view, the power contained in Rule 8(3)(c) is wide enough in its terms to include a strike out application based on those grounds. Such an application, if successful, would result in the First-tier Tribunal concluding that the relevant part of the appellant’s case could not succeed. A power to strike out could also be said to be part of the power of regulation by the First-tier Tribunal of its procedure under Rule 5(1) (which was the view of the Upper Tribunal), but Rule 8(3)(c) is enough. There is no need to imply a power. It is worth observing that the equivalent provision inCPR 3.4 (2) separates out a case where a statement of case discloses no reasonable grounds for bringing or defending the claim from a case where the statement of case is an abuse of the court’s process. But for the First-tier Tribunal the Tribunal Procedure Committee has chosen a different but composite criterion of no reasonable prospect of success, which is wide enough to cover appeals which are legally hopeless as well as appeals which can be said to amount to an abuse of process. There is in my view express power to strike out on both grounds.”
