(d)... An application under this rule is not void and ineffective merely because sub-para (a) had been pleaded together with sub-paras (b)–(d).” [32] Moreover, the concept of “abuse of process” under Rule 19(1)(d) is broad and encompasses various situations where the court's process is being misused. As explained in Middy Industries Sdn Bhd v Arensi-Marley (M) Sdn Bhd [2013] 3 MLJ 511 by the Court of Appeal, abuse of process “includes consideration of public policy and interest of justice” and “the categories of conduct rendering a claim frivolous, vexatious or an abuse of process are not closed and will depend on all the relevant circumstances of the case.” [33] Therefore, Shaoxing's choice to rely specifically on Order 18 Rule 19(1)(d) does not preclude the court from considering whether the claim discloses a reasonable cause of action or is frivolous or vexatious. The court must look at the substance of the application and the nature of the pleadings to determine whether they constitute an abuse of process. [34] In the present case, Shaoxing's contention is that Khaleeg's claim constitutes an abuse of process because it seeks to relitigate issues that have already been decided in Suit 378 and attempts to vary a final and conclusive judgment. This is a proper ground for an application under Order 18 Rule 19(1)(d), and the court has the jurisdiction to strike out the claim on this basis. Res Judicata and Abuse of Process [35] The Defendant contends that Khaleeg's claim is barred by the doctrine of res judicata as the issues concerning the AR Bright invoices were already raised, argued, and decided in Suit 378. The Defendant points to the written submissions, oral arguments, and the High Court's judgment in Suit 378, which specifically addressed the issue of the AR Bright invoices. [36] The Defendant characterises the present suit as an impermissible attempt to relitigate matters that have been conclusively determined, which is contrary to the public policy principle that there should be finality in litigation (interest rei publicae ut sit finis litium). [37] Khaleeg argues that its claim is not an attempt to relitigate issues from Suit 378 but rather seeks consequential reliefs that arise from the Judgment. Khaleeg contends that it is not challenging the validity of the Judgment but rather seeking to enforce rights that it claims arise from the Judgment. [38] Khaleeg submits that the cause of action in this suit only accrued after the Federal Court's decision on 22.8.2024, which marked the point at which all material facts were in existence to render the cause of action complete. [39] After careful consideration of the parties' submissions and the pleadings, I find that Khaleeg's claim indeed falls foul of the doctrine of res judicata and constitutes an abuse of the court process. [40] The doctrine of res judicata, as explained by the Supreme Court in Asia Commercial Finance (M) Bhd v Kawal Teliti Sdn Bhd [1995] 3 MLJ 189, is founded on two maxims: first, that it is in the public interest that there should be finality in litigation (interest rei publicae ut sit finis litium), and second, that no one ought to be vexed twice for the same cause of action (nemo debet bis vexari pro eadem causa). [41] There are two types of estoppel per rem judicatum: cause of action estoppel and issue estoppel. The former arises when a cause of action has been determined in a final judgment, while the latter prevents a party from challenging the correctness of a decision on an issue that has been determined in a previous final judgment. [42] In the present case, both types of estoppel are applicable. The issue of Khaleeg's liability for the AR Bright invoices was expressly raised and determined in Suit 378. This is evident from the High Court's grounds of judgment, which specifically addressed Khaleeg's argument that “the five Invoices were addressed to AR Bright and not to Khaleeg” and rejected this defence. [43] The High Court in Suit 378 held: “PW-1 had also testified that he received instructions from the defendant that the Goods are to be sent to AR Bright, and the defendant will be responsible for payment. His testimony remains unrebutted. AR Bright is also only identified as a consignee in the Statement of Account. The defendant is the party identified as the buyer.” [44] This finding was upheld by the Court of Appeal and, effectively, by the Federal Court when it dismissed Khaleeg's application for leave to appeal. The issue of Khaleeg's liability for the AR Bright invoices has therefore been conclusively determined. [45] Khaleeg attempts to circumvent the doctrine of res judicata by framing its claim as seeking “consequential reliefs” arising from the Judgment. However, this is a transparent attempt to relitigate the same issue through a different legal mechanism. Khaleeg's claim for an assignment of the benefit of the AR Bright invoices is predicated on the argument that it should not have been held liable for these invoices in the first place – an argument that has already been rejected by the courts. [46] Furthermore, the relief sought by Khaleeg in paragraph 8.1 of the Statement of Claim – a declaration that the Judgment “adalah tidak sah untuk dikuatkuasakan selagi pematuhan dalam ertikata perenggan (a) dalam Penghakiman tersebut belum dipatuhi oleh Defendan” (is not valid for enforcement as long as compliance in the sense of paragraph (a) in the Judgment has not been complied with by Shaoxing) – is a direct challenge to the validity and enforceability of the Judgment. This is precisely the kind of collateral attack on a final judgment that the doctrine of res judicata is designed to prevent. [47] Khaleeg's reliance on Tan Kong Min v Malaysian National Insurance Sdn Bhd [2006] 1 MLJ 601 to support the argument that Khaleeg's cause of action in this new suit only arose after the Federal Court's decision on 22.8.2024, which marked the point where all appeal processes were exhausted and the judgment became final is misplaced. That case, decided by the Federal Court, involved a mortgagee claiming the shortfall after a foreclosure and auction sale of the mortgaged property. The Federal Court held that the mortgagee's cause of action to recover the differential amount owing accrued only after the property was sold and the differential amount ascertained. However, this principle does not assist Khaleeg in the present case. In Tan Kong Min, the mortgagee was pursuing the same cause of action (recovery of money lent) against the same debtor, simply determining when that cause of action accrued for limitation purposes. Here, Khaleeg is attempting to create an entirely new cause of action by reframing an issue that has already been determined. The material facts relating to the AR Bright invoices were fully known to Khaleeg during Suit 378, the issue of its liability for these invoices was expressly determined in that suit, and Khaleeg had every opportunity to raise the assignment argument at that time. The distinguishing feature is that in Tan Kong Min, the second action was a natural extension of the first action (recovering the balance), whereas here, Khaleeg's claim is an attempt to reverse or modify the effect of the final judgment in the earlier case. [48] Similarly, Khaleeg's reference to Mega Palm Sdn Bhd v Hun Tee Siang [2022] 4 MLRA 200 to support the argument that the reliefs sought in this suit are different from those in Suit 378, so Khaleeg is entitled to file this new action does not assist its case. In Mega Palm, the Court of Appeal dealt with a situation where residents of Country Heights Damansara had sued the developer regarding the maintenance of basic infrastructure, resulting in a consent order. When the developer failed to comply with the consent order, the residents filed a fresh action to enforce it. The Court of Appeal held that a fresh action was appropriate because the consent order contained terms that went beyond the original reliefs sought in the first action, specifically regarding a resource center relocation which was not part of the original prayers. This is distinguishable from the present case in two critical respects: first, in Mega Palm, the second action sought to enforce a consent order that was not fully honoured, whereas here, Khaleeg is seeking to vary the effect of a contested judgment; second, in Mega Palm, the fresh action was premised on additional terms in the consent order that were not part of the original suit, whereas here, Khaleeg's claim directly revisits the same dispute over liability for the AR Bright invoices that was conclusively determined in Suit 378. The underlying cause of action remains identical - whether Khaleeg is liable for payment of the AR Bright invoices - and Khaleeg is merely attempting to repackage this same dispute in different legal terminology. [49] The Federal Court in Scott & English (M) Sdn Bhd v Yung Chen Wood Industries Sdn Bhd [2018] 6 CLJ 271 emphasised that “all litigation must come to an end” and that a party “could not relitigate” matters that have been finally determined. This principle applies squarely to the present case. Khaleeg has exhausted all avenues of appeal in Suit 378 and cannot now seek to relitigate the same issue through a fresh suit. [50] In Sayyid Shah bin Abdullah v Ng Seing Liong (joint receiver and manager) & Ors [2023] MLJU 1644, the High Court of Malaya aptly described a similar situation as “old wine in a new bottle: an attempt to resurrect issues directly and actively tried, contested and already adjudicated.” In that case, the plaintiff had previously filed an originating summons challenging the appointment of a receiver and manager (R&M) for a company under a debenture, which was dismissed. After the original R&M resigned and was replaced by new R&Ms appointed by the same bank under the same debenture, the plaintiff filed a fresh originating summons challenging the appointment of the new R&Ms on essentially the same grounds. Liza Chan J held that both cases arose from “the same set of facts, background, issues and circumstances” with the only difference being that “the name of [the first R&M] was replaced by [the names of the new R&Ms].” The court found that the action was undoubtedly caught by res judicata and constituted an abuse of process. This description is equally applicable to the present case, where Khaleeg has merely repackaged the same underlying dispute regarding liability for the AR Bright invoices into a claim for assignment of those invoices, with both actions calling into question the same contractual relationship and transaction between the parties, and both founded on the same basic contention that Khaleeg should not be liable for invoices addressed to AR Bright. [51] I therefore find that Khaleeg's claim is barred by the doctrine of res judicata and constitutes an abuse of the court process. The claim represents an impermissible attempt to relitigate matters that have been conclusively determined and to undermine the finality of the Judgment in Suit 378. Lack of Jurisdiction to Vary the Judgment [52] The Defendant contends that this court lacks jurisdiction to grant the reliefs sought by Khaleeg, as they would amount to varying or amending the Judgment in Suit 378. The Defendant relies on authorities such as Hock Hua Bank Bhd v Sahari Bin Murid [1981] 1 MLJ 143 (FC) and Scott & English (M) Sdn Bhd v Yung Chen Wood Industries Sdn Bhd [supra] (CA) to support this contention. [53] Khaleeg argues that it is not seeking to vary or amend the Judgment but rather to enforce rights arising from it. Khaleeg contends that the jurisdiction for filing this action is derived from the Judgment itself, and the court has jurisdiction to grant the consequential reliefs sought. [54] I find that the reliefs sought by Khaleeg would indeed amount to varying or amending the Judgment in Suit 378, which this court lacks jurisdiction to do. [55] It is a well-established principle, as affirmed by the Federal Court in Hock Hua Bank Bhd, that “clearly the court has no power under any application in the same action to alter vary or set aside a judgment regularly obtained after it has been entered or an order after it is drawn up.” This principle applies with even greater force when the judgment has been affirmed on appeal. [56] As the Court of Appeal explained in Scott & English: “There would be total mayhem in the judicial system if a lower court could amend an order affirmed by a higher court. The position is that unless appealed against, an order of a trial court stands final, binding and conclusive as pronounced by the trial court. If appealed against, an order of the trial court stands final, binding and conclusive as pronounced by the higher or highest court.” [57] In the present case, the Judgment in Suit 378 has been affirmed by the Court of Appeal and, effectively, by the Federal Court (through the dismissal of the leave application). It stands final, binding, and conclusive. This court does not have the jurisdiction to vary or amend this Judgment, either directly or indirectly. [58] The reliefs sought by Khaleeg would, if granted, effectively vary the Judgment. The declaration sought in paragraph 8.1 of the Statement of Claim – that the Judgment is not valid for enforcement – directly challenges the enforceability of the Judgment. Similarly, the orders sought to stay or suspend enforcement of the Judgment (paragraphs 8.1.1,
