19 The first ground was not argued before Efthim AsJ. The second ground, I was told, was raised below although it did not appear in the written submissions on behalf of the plaintiff below nor was reference made to it in the judgment of Efthim AsJ. It was submitted that Efthim AsJ fell into legal error in not considering the legal effect of the reservation, though I note that it is unclear whether Efthim AsJ had the benefit of the argument as it was put to me. The importance in the interests of efficiency, expedition and finality of litigation of parties presenting their arguments fully and clearly at first instance cannot, and must not be, underestimated.[14] A considered judgment on all points enables parties fully to evaluate the correctness of the decision and the likely merits of appeal. In this matter, the hearing before Efthim AsJ took some time and His Honour reserved his decision for consideration and His Honour's reasons reflect his consideration. But as Efthim AsJ did not have the benefit of argument on the first ground, at least, the parties did not have the benefit of His Honour's consideration on that point and the opportunity to evaluate the correctness of his reasoning, before the occasion of the application for leave to appeal. The failure of a party to raise below an argument on which that party relies to contend that the decision below was affected by error may be a factor that is relevant to the Court's exercise of discretion to grant or refuse leave to appeal. In appropriate cases, the non-advertence to an argument below may be sufficient reason in itself for the Court to refuse leave. It is conceivable that in some circumstances, it may amount to an abuse of process for a party to appeal or seek leave to appeal from a decision of the Associate Judge where the party has not raised all arguments below. Parties should not treat applications before Associate Judges as "dress rehearsals" for appeal.[15] It is unfortunate that Efthim AsJ did not have the advantage of the case as it was presented before me. That being said, it is not reason in this matter to refuse leave to appeal as the application was able to proceed without prejudice to the other parties, save presumably with respect to costs.
