The appeal court may impose or vary conditions upon which an appeal may be brought but it should only exercise its powers under CPR 52.9(1)(c) where there is a compelling reason to do so. It was not appropriate to impose a condition that the appellant satisfy an outstanding costs order where the order related to a different aspect of the proceedings and concerned a summary judgment hearing at which the appellant did not appear (Star Reefers Pool Inc v JFC Group Co Ltd).
