99 The Sahins sought leave to add a further ground of appeal that the bank and the insurer could have made their stay application in the Court of Appeal as they knew of the facts in the first and second proceeding at the time of the appeal hearing. I would refuse leave to appeal on this ground as it has no prospect of succeeding. The appropriate forum to pursue the stay application was in the trial division - it was not a matter amenable to determination on appeal. Nevertheless, in my opinion, it might have been expected that the bank, as a sophisticated litigant represented as it was by competent counsel and solicitors, would have brought the existence of the counterclaim to the Court's attention. However, on this appeal, counsel informed the Court that this was not done. At the very least, that is unfortunate. Had the bank through its legal advisers done so, the Court would no doubt have raised the matter with the Sahins to ensure that they were not unfairly disadvantaged by being in ignorance of their rights.
