It is pertinent to note that this Court had on 26.8.2021 (26.8.2021 Order) granted an order to dispose the said Equity in PW 157. Thus, in essence, this Court is functus officio to revisit the 26.8.2021 in the absence of any evidence that the said 26.8.2021 was irregularly obtained due to an illegality, breach of rules of natural justice, or lack S/N /kJsuZaM/0eUdcmzlt1qZw of jurisdiction. The law on this has been clearly stated in Badiaddin Mohd Mahiddin & Anor v Arab Malaysian Finance Berhad [1998] 1 MLJ 393 where Mohd Azmi FCJ had held: “It is of course settled law as laid down by the Federal Court in Hock Hua Bank's case that one High Court cannot set aside a final order regularly obtained from another High Court of concurrent jurisdiction. But one special exception to this rule (which was not in issue and therefore not discussed in Hock Hua Bank) is where the final judgment of the High Court could be proved to be null and void on ground of illegality or lack of jurisdiction so as to bring the aggrieved party within the principle laid down by a number of authorities culminating in the Privy Council case of Isaacs v Robertson [1985] AC 97 where Lord Diplock while rejecting the legal aspect of voidness and voidability in the orders made by a court of unlimited jurisdiction, upheld the existence of a category of orders of the court '… which a person affected by the order is entitled to apply to have set aside ex debito justitiae in the exercise of the inherent jurisdiction of the court, without his needing to have recourse to the rules that deal expressly with proceedings to set aside orders for irregularity, and give to the judge a discretion as to the order he will make'. The Privy Council through Lord Diplock also emphasized that the courts in England have not closed the door as to the type of defects in the final judgment of the court that can be brought into the category that attracts ex debito justitiae the right to have it set aside without going into the appeal procedure, 'save that specifically it includes orders that have been obtained in breach of rules of natural justice'. Similarly in this country, the statement of Abdoolcader J (as he then was) in Eu Finance Bhd v Lim Yoke S/N /kJsuZaM/0eUdcmzlt1qZw Foo [1982] 2 MLJ 37 at p 39 provides the correct guideline on the subject: The general rule is that where an order is a nullity, an appeal is somewhat useless as despite any decision on appeal, such an order can be successfully attacked in collateral proceedings; it can be disregarded and impeached in any proceedings, before any court or tribunal and whenever it is relied upon — in other words, it is subject to collateral attack. In collateral proceedings, the court may declare an act that purports to bind to be non-existent. In Harkness v Bells' Asbestos and Engineering Ltd [1967] 2 QB 729, Lord Diplock LJ (now a Law Lord) said (at p 736) that 'it has been long laid down that where an order is a nullity, the person whom the order purports to affect has the option either of ignoring it or of going to the court and asking for it to be set aside'. For my part, I must hasten to add that apart from breach of rules of natural justice, in any attempt to widen the door of the inherent and discretionary jurisdiction of the superior courts to set aside an order of court ex debito justitiae to a category of cases involving orders which contravened 'any written law', the contravention should be one which defies a substantive statutory prohibition so as to render the defective order null and void on ground of illegality or lack of jurisdiction”.
