“25 Supplementary powers of Upper Tribunal (1) In relation to the matters mentioned in subsection (2), the Upper Tribunal– (a) has, in England and Wales …, the same powers, rights, privileges and authority as the High Court, … (2) The matters are – (a) the attendance and examination of witnesses, (b) the production and inspection of documents, and (c) all other matters incidental to the Upper Tribunal's functions. (3) Subsection (1) shall not be taken – (a) to limit any power to make Tribunal Procedure Rules; (b) to be limited by anything in Tribunal Procedure Rules other than an express limitation.” (a) has, in England and Wales …, the same powers, rights, privileges and authority as the High Court, (a) the attendance and examination of witnesses, (b) the production and inspection of documents, and (c) all other matters incidental to the Upper Tribunal's functions. (a) to limit any power to make Tribunal Procedure Rules; (b) to be limited by anything in Tribunal Procedure Rules other than an express limitation.”
“Parliament was obviously aware of the powers of the High Court, both those which are inherent, and those specifically conferred by statute. Section 25 therefore seems to me to be intended to be read literally and applied generally, and to invest the Upper Tribunal with the powers of the High Court in relation to all matters incidental to its functions; the critical limitation in section 25(2)(c) is supplied by the reference to the functions of the Tribunal, and does not depend on the source of the power or the terms in which it has been conferred on the High Court. Parliament could obviously make explicit an intention that the Upper Tribunal was not to possess a particular power, but where it has not done so, and where no express limitation has been imposed by tribunal procedure rules as contemplated by section 25(3)(b), the Upper Tribunal must be taken to have the same powers as the High Court in relation to all matters incidental to its functions.”
“The Upper Tribunal may only undertake a review of a decision pursuant to rule 45(1) (review on an application for permission to appeal).”
“On receiving an application for permission to appeal the Upper Tribunal may review the decision in accordance with rule 46 (review of a decision), but may only do so if – (a) when making the decision the Upper Tribunal overlooked a legislative provision or binding authority which could have had a material effect on the decision; or (b) since the Upper Tribunal’s decision, a court has made a decision which is binding on the Upper Tribunal and which, had it been made before the Upper Tribunal’s decision, could have had a material effect on the decision. …”
“The judgment [of the Court of Appeal in the Patel case] is clearly binding on the Upper Tribunal in all its Chambers, and it is in our judgment of considerable importance as much for what it does not say as for what it does. The court was concerned to discover whether the Upper Tribunal had power to set aside a decision that, in the tribunal’s view, had been reached in the absence of a full appreciation of the facts. In these circumstances the Court’s concentration on the review power under s.10 of the 2007 Act and the absence of any reference to either the inherent power of a superior court of record or the powers given by s.25 must constitute a decision that those powers either do not exist or, if they do, were wholly irrelevant to the issue before the court.”
