"If a Lord Justice of Appeal, having studied the matter on paper, is satisfied that there is an arguable case and grants leave, I think it would require some very cogent reasons for disagreeing with his decision and it would certainly not be a reason that the court who was asked to reconsider his decision did not itself think that the matter was arguable. ... But the point I am making is that if one Lord Justice thinks an appeal is arguable, it is really necessary in my view for anybody seeking a reconsideration of that to be able to point fairly and unerringly to a factor which was not drawn to the Lord Justice's attention because perhaps it did not feature in the documents which had been studied or to the fact that he has overlooked some statutory provision which is decisive or some authority which is decisive, in the sense that the appeal will inevitably fail. That is really what leave to appeal is directed at - screening out appeals which inevitably fail."
"... it should be borne in mind prior to making such an application [that is an application to set aside] that this court is likely to be very unsympathetic to it being made if it will in effect involve the parties in exactly the same expense as determining the appeal itself, and will not necessarily save the time of the court but risk the court having to have two hearings when only one would be necessary if there were no application to set aside. It is appreciated that any litigant will feel aggrieved by being faced with delay in waiting to have an appeal heard which has no prospect of success. However, the only consequence of applications such as this having to be heard is to delay the hearings of appeals the determination of which serves some purpose. There are circumstances where an application to set aside leave is fully justified, but the present application does not fall within that category."
"(1) The appeal court may- (a)strike out the whole or part of an appeal notice; (b) set aside permission to appeal in whole or in part; (c) impose or vary conditions upon which an appeal may be brought. (2) The court will only exercise its powers under paragraph (1) where there is a compelling reason for doing so."
"This tempting provision should not lure advocates into tactical skirmishing or into manoeuvres designed to wear down the opposition. Save in exceptional circumstances, it is a misuse of the court's resources and a waste of costs for the court to consider the substance of an appeal on some intermediate date between the permission hearing and the full appeal. Rule 52.9(2) provides that the power will only be exercised where there is `a compelling reason'. One example of a compelling reason may be that the appellant misled the appeal court on an application for permission made without notice to the other party."
