This approach is consistent with settled principle. In Ahmad Saidi (supra), the Court of Appeal held, in substance, that once the order complained of had come to an end, “there was no longer a valid lis” before the court, and the court would not “act in vain” or grant academic relief. The same theme is seen in Bar Council Malaysia v Tun Dato’ Seri Arifin bin Zakaria & Ors [2020] 4 MLJ 773, where the Federal Court observed that where the alleged illegality had been overtaken by subsequent events, the subject matter of the dispute was no longer in existence, no effective remedy could be granted, and the underlying factual substratum had disappeared. I do not, of course, treat those public law authorities as direct analogues on all fours with the present private law appeal. But the narrower principle for which they are cited remains sound: where the very subject matter for which judgment is sought has ceased to be a live controversy, the Court must be astute not to make an order that no longer serves a juridical purpose. On the undisputed facts here, the order for payment of the principal sum plainly fell into that category.
