The Federal Court in The Government of Malaysia & Anor v Aminah bt Ahmad (suing in her personal capacity and on behalf of 56 retired members of the public service) [2023] 5 MLJ 32 and Court of appeal case of Aminah bt Ahmad (suing in her personal capacity and on behalf of 56 retired members of the public services) v The Government of Malaysia & Anor [2022] 4 MLJ 74 where at the Court of Appeal held: “[51] The general common law principle is that the decision of a court on a point of law is declaratory in nature. Courts declare what is and what has always been the law and it would thus have both retrospective and prospective effect as well. As was stated in the decision of this court in Abdillah bin Labo Khan v Public Prosecutor [2002] 3 MLJ 298; [2002] 3 CLJ 521: ‘It is a fundamental principle of adjudicative jurisprudence that all judgments of a court are retrospective in effect’. However, the law has evolved to afford courts, in appropriate cases, with a discretion to mitigate foreseeable adverse consequences and hardship, especially if it would otherwise affect a class of the citizenry. This may sometimes be achieved by invoking the doctrine of ‘prospective overruling’; a ruling that is to be effective only prospectively. As Lord Nicholls described it in Re Spectrum Plus Ltd; National Westminster Bank plc v Spectrum Plus Ltd and others [2005] UKHL 41: ‘Prospective overruling’, sometimes described as ‘non-retroactive overruling’, is a judicial tool fashioned to mitigate these adverse consequences. It is a shorthand description for court rulings on points of law which, to greater or lesser extent, are designed not to have the normal retrospective effect of judicial decisions. … [54] In the case of Sarwan Kumar v Madan Lal Aggrawal 2003 AIR 1475 (SC), the Supreme Court of India stated at p 1481 as follows: [13] … Under the doctrine of ‘prospective overruling’ the law declared by the court applies to the cases arising in future only and its applicability to cases which have attained finality is saved because the repeal would otherwise work hardship to those who had entrusted to its existence. Invocation of the doctrine of ‘prospective overruling’ is left to the discretion of the court to mould with the justice of the cause or the matter before the court. [55] In Ling Peek Hoe & Anor v Ding Siew Ching and another appeal [2017] 5 MLJ 385, Richard Malanjum CJ (Sabah and Sarawak) (as His Lordship then was) in delivering the judgment of the Federal Court, after referring to the decisions of the Indian Supreme Court in Sarwan Kumar and Golak Nath, stated thus at p 395: [27] We are of the view that the rationale on the applicability of the doctrine of prospective overruling as discussed by the Indian Supreme court in the above cases is logical and sound. We have no good reason not to adopt it. [56] As was pointed out by the Federal Court in Ling Peek Hoe, ‘prospective overruling’ has been applied by our courts. In the case of Dato’ Yap Peng, the Supreme Court applied the doctrine so that its decision would leave undisturbed earlier convictions or acquittals. In Mamat bin Daud & Ors v Government of Malaysia [1988] 1 MLJ 119, the Supreme Court by a majority declared null and void s 298A of the Penal Code as being a provision that Parliament had no power to make under the Federal Constitution but ordered that its ruling should only take effect from the date of its order, namely, 13 October 1987. The jurisdiction was again invoked in Repco Holdings Bhd v Public Prosecutor [1997] 3 MLJ 681, this time by the Court of Appeal, when it declared both s 129(2) of the Securities Industry Act 1983 and s 39(2) of the Securities Commission Malaysia Act 1993 to be unconstitutional, null and void [57] In Singapore, the Court of Appeal also found it had jurisdiction to apply the doctrine of prospective overruling and held that its jurisdiction, unlike that of the courts in India, would not be limited to constitutional cases. … [59] ‘Prospective overruling’ is clearly an exception to the general rule. We would also emphasise, and join the chorus, in cautioning that the doctrine of prospective overruling is a jurisdiction that is not to be employed lightly but with circumspection and only in exceptional circumstances. In cases involving the avoidance of a law, which has stood for some time, for being in contravention of the Federal Constitution, the doctrine of prospective overruling would be available to give effect to the raison d’etre for its existence. It would be available to the court to, in the words of Abdoolcader SCJ, ‘… give such retroactive effect to its decision as it thinks fit to be moulded in accordance with the justice of the cause or matter before it …’. [60] For the reasons given above, and to mitigate the adverse consequences and hardship that the decision of the court may have on pensioners, we are of the view that this is an appropriate case, and in the public interest, for an order that the decision of this court is only to take effect prospectively from the date of the decision of this court ie 13 January 2022, and we so order. For the avoidance of any doubt, this decision would have effect on any pending proceedings, whether pending at first instance or pending appeal, in respect of issues relating to the declarations made.”
