New Judgment: Public Prosecutors Office of the Athens Court of Appeal v O’Connor [2022] UKSC 4 – UKSC Blog
‘The Respondent was ordered to be extradited to Greece for the purposes of conducting a criminal prosecution against him. On that day, the Respondent’s solicitor stated orally in court that an appeal would be lodged against the extradition order, and on 16 December 2015, the notice of application for leave to appeal was filed with the Court. However, due to an oversight, the solicitor failed to serve the notice on the Crown Solicitor’s Office (on behalf of Greece) until about three weeks later.’
