Leach JA, in his concurring judgment, expressed the view (obiter) that when parties settle litigation after leave to appeal has been granted, the settlement brings the litigation to an end entirely, removing the disputes from the court's jurisdiction altogether. In such circumstances, there is no longer any 'appeal' that the court has power or discretion to deal with, rather than merely an appeal that has become moot. This reasoning follows the approach in Port Elizabeth Municipality v Smit and the English decision in Sun Life Assurance Company of Canada v Jervis, which require the existence of a 'living issue' or 'matter in actual controversy' as an essential quality of an appeal. Leach JA distinguished cases like Sebola v Standard Bank, Land en Landbouontwikkelingsbank van Suid-Afrika v Conradie, and The Merak S on the basis that in those cases there were still live issues (particularly regarding costs) remaining between the parties despite other aspects having become academic. The majority judgment also noted, obiter, that questions concerning the precise requirements of court rules and procedure are appropriately within the jurisdiction of the Rules Board for Courts of Law, which is statutorily empowered to review and amend rules regulating practice, procedure, and the form and contents of court process. The court also observed that it has repeatedly cautioned against deciding matters without tested argument from both sides, which would be the case in this unopposed appeal.
