Regina v Chapman [2013] EWCA Crim 1370; [2013] WLR (D) 318
“Once an appeal had been constituted by filing a notice of appeal in time or by obtaining an extension of time from the court, the order of the court below was subject to review and not final and the court could not justify refusing to allow the defendant to take advantage of a change in the law which occurred between the filing of the notice of appeal and the hearing itself.”
