“(1) The Court of Appeal or the High Court will not re-open a final determination of any appeal unless— (a) It is necessary to do so in order to avoid real injustice; (b) The circumstances are exceptional and make it appropriate to re-open the appeal; and (c) There is no alternative effective remedy.”
“[40]… There is the strongest public interest in finality. The jurisdiction is probably confined to procedural errors, particularly as there are alternative remedies for fresh evidence cases through the Criminal Cases Review Commission.”
“[9] We would draw particular attention to the expectation that the jurisdiction under Crim PR 17.27 will not be exercised unless something has developed after the determination of the appeal. The jurisdiction is not designed to allow a disappointed party to the appeal to reconsider his arguments, material and evidence and come back to the court to have another go. Furthermore, we would emphasise the importance of finality in extradition cases by noting the observations of Lord Thomas in Abu Hamza v. Government of the United States[2012] EWHC 2736 (Admin) at [21] and [22], namely that there is an overwhelming public interest in both the proper functioning of extradition arrangements and in honouring extradition treaties, as well as there being an equally high importance in the finality of litigation. Finality of litigation is particularly important in extradition cases: ‘because of the public interest in an efficient process, the need to adhere to international obligations and to avoid a recurrence of the delays which have so disfigured the extradition process in the past and to which successive appeals over time can subject it’.” ‘because of the public interest in an efficient process, the need to adhere to international obligations and to avoid a recurrence of the delays which have so disfigured the extradition process in the past and to which successive appeals over time can subject it’.”
