12 Time limits for appeals to the Supreme Court of devolution issues and compatibility issues
1 This article applies where—
(a) a devolution issue other than a convertible devolution issue has, before the relevant date, been determined by a court of two or more judges of the High Court of Justiciary (whether in the ordinary course of proceedings or on a reference under paragraph 9 of Schedule 6 to the Scotland Act 1998);
(b) an application to the High Court of Justiciary for permission to appeal under paragraph 13(a) of Schedule 6 to the 1998 Act has, before the relevant date, been refused; and
(c) no application has by that date been made to the Supreme Court for permission to appeal under paragraph 13(a) of that Schedule.
2 In relation to such a case, paragraph 13B of that Schedule has effect as if the reference to the date on which the High Court refused permission under that paragraph were a reference to 22nd April 2013.
