“13 Right to appeal to Court of Appeal etc. (1) For the purposes of subsection (2), the reference to a right of appeal is to a right to appeal to the relevant appellate court on any point of law arising from a decision made by the Upper Tribunal other than an excluded decision. (2) Any party to a case has a right of appeal, subject to subsection (14). (3) That right may be exercised only with permission (or, in Northern Ireland, leave). (4) Permission (or leave) may be given by– (a) the Upper Tribunal, or (b) the relevant appellate court, on an application by the party. (5) An application may be made under subsection (4) to the relevant appellate court only if permission (or leave) has been refused by the Upper Tribunal. (6) The Lord Chancellor may, as respects an application under subsection (4) that falls within subsection (7) and for which the relevant appellate court is the Court of Appeal in England and Wales or the Court of Appeal in Northern Ireland, by order make provision for permission (or leave) not to be granted on the application unless the Upper Tribunal or (as the case may be) the relevant appellate court considers– (a) that the proposed appeal would raise some important point of principle or practice, or (b) that there is some other compelling reason for the relevant appellate court to hear the appeal. (7) An application falls within this subsection if the application is for permission (or leave) to appeal from any decision of the Upper Tribunal on an appeal under section 11. (8) For the purposes of subsection (1), an “excluded decision” is– … (c) any decision of the Upper Tribunal on an application under section 11(4)(b) (application for permission or leave to appeal), (d) a decision of the Upper Tribunal under section 10– (i) to review, or not to review, an earlier decision of the tribunal, (ii) to take no action, or not to take any particular action, in the light of a review of an earlier decision of the tribunal, or (iii) to set aside an earlier decision of the tribunal, (e) a decision of the Upper Tribunal that is set aside under section 10 (including a decision set aside after proceedings on an appeal under this section have been begun), or (f) any decision of the Upper Tribunal that is of a description specified in an order made by the Lord Chancellor.”
“10 Review of decision of Upper Tribunal (1) The Upper Tribunal may review a decision made by it on a matter in a case, other than a decision that is an excluded decision for the purposes of section 13(1) (but see subsection (7)).”
“43.— Setting aside a decision which disposes of proceedings (1) The Upper Tribunal may set aside a decision which disposes of proceedings, or part of such a decision, and re-make the decision or the relevant part of it, if— (a) the Upper Tribunal considers that it is in the interests of justice to do so; and (b) one or more of the conditions in paragraph (2) are satisfied. (2) The conditions are— (a) a document relating to the proceedings was not sent to, or was not received at an appropriate time by, a party or a party's representative; (b) a document relating to the proceedings was not sent to the Upper Tribunal at an appropriate time; (c) a party, or a party's representative, was not present at a hearing related to the proceedings; or (d) there has been some other procedural irregularity in the proceedings. (3) Except where paragraph (4) applies, a party applying for a decision, or part of a decision, to be set aside under paragraph (1) must make a written application to the Upper Tribunal so that it is received no later than 1 month after the date on which the Upper Tribunal sent notice of the decision to the party. (4) In an asylum case or an immigration case, the written application referred to in paragraph (3) must be sent or delivered so that it is received by the Upper Tribunal— (a) where the person who appealed to the First-tier Tribunal is in the United Kingdom at the time that the application is made, no later than twelve days after the date on which the Upper Tribunal or, as the case may be in an asylum case, the Secretary of State for the Home Department, sent notice of the decision to the party making the application; or (b) where the person who appealed to the First-tier Tribunal is outside the United Kingdom at the time that the application is made, no later than thirty eight days after the date on which the Upper Tribunal sent notice of the decision to the party making the application. (5) Where a notice of decision is sent electronically or delivered personally, the time limits in paragraph (4) are ten working days.”
“… the rule is concerned with how the Upper Tribunal handed the claimant’s application for permission to appeal. It does not provide a means of challenge to the decision itself or the reason on which it is based.”
