If so, could it have been discovered and exposed either in the Magistrate's Court Actions or, at the hearing of the application to set aside the default judgment or, on the appeal before me from the refusal of the learned Magistrate to do so? … Clearly, there cannot be wilful concealment amounting to fraud unless there was in the first place a duty imposed by law upon the party concerned to make the disclosure alleged. [Emphasis is ours] [32] The above authorities I have discussed collectively establish that: i. First, the “fraud” spoken of in s. 44 of the EA 1950 is actual, positive fraud, not constructive fraud. The “actual positive fraud, must be a meditated and intentional contrivance to keep the parties and the court in ignorance” of the relevant matter. ii. Secondly, there must be malus animus, a mala mens “acting in order to take an undue advantage … for the purpose of 17! ! actually and knowingly defrauding” the other party; mere overstatement of rights or irregularity is insufficient. iii. Thirdly, charges of fraud and collusion must be strictly proved by the party alleging them, by established facts or by inferences legitimately drawn from the totality of those facts. Suspicion, surmise and conjecture are not permissible substitutes. iv. Fourthly, where the alleged fraud consists of non-disclosure of material evidence, the authorities recognise a duty of utmost good faith (uberrima fides) on a litigant who moves the Court, particularly one seeking discretionary relief. A deliberate decision to withhold a “vital document” in order to gain an advantage may amount to fraud on the Court. v. Fifthly, that, once fraud is proved, it is not necessary for the innocent party to show that the fresh evidence could not with reasonable diligence have been obtained for the original trial. Fraud “unravels all”; vi. But it bears emphasis that this relaxation of the diligence requirement does not dilute the threshold for proving fraud in the first place. On the contrary, the cases insist that a judgment, especially one given after a full trial, is not lightly disturbed; clear and cogent evidence of actual fraud is required. 18! ! IV. Issues [33] Against this backdrop, the issues that arise for determination in this application may be framed as follows: a) Whether Tega perpetrated “actual positive fraud”; and b) Whether, in all the circumstances, this is an appropriate and proportionate case to invoke the exceptional jurisdiction under s 44 of the EA 1950 to impeach a judgment. [34] I will address these issues in turn. a) Whether Tega perpetrated “actual positive fraud” [35] Under this heading, this Honourable Court is called upon to decide whether, on the facts of Suit 15, Tega owed a legal duty to disclose the MDA Recall Notice to the Court and to MWH; and, if so, whether MWH has proven to the requisite standard that Tega deliberately and dishonestly withheld that Notice to procure the impugned judgment. [36] MWH seeks to impeach the judgment, alleging that Tega fraudulently failed to disclose the MDA Notice, which MWH contends affects Tega’s entire product line from its inception. Specifically, MWH argues that Version 1, Version 2, and Version 3 were all "contaminated" by "Germanium," their key ingredient. 19! ! [37] In my judgment, the starting point must be to identify precisely what was at issue in Suit 15. As learned counsel for Tega correctly pointed out, Suit 15 concerned only Versions 1–3 of Tega’s products—all products containing organic germanium and marketed under the “OGE Bio-Aquacel” brand. [38] The pleadings in Suit 15 specifically identified Versions 1, 2, and 3 as the products at issue. During the trial, Versions 1, 2, and 3 were: a) Exhibited (Exhibits P1A-P1B, P2A-P2C, P3A-P3B); b) Tested by expert witnesses; c) Distributed by MWH during the relevant period (2017-2020); and d) Subject to the contamination allegations. [39] It is undisputed that the MDA Notice pertained to one of Tega’s later products called “Bio-Aquacel Eye Safe” (“Version 4”). Counsel for Tega emphasized that Versions 1, 2, and 3 were consistently sold as “cosmetic products.” In contrast, Version 4 was registered as a “medical device.” Counsel for Tega underscored that Version 4, “Bio-Aquacel Eye Safe,” did not exist when Suit 15 was commenced, was only marketed in November 2020, and was manufactured by one Farmasia as a medical device under a regulatory regime distinct from that applicable to cosmetic products. [40] In deliberating this point, I am cognizant that there is no dispute that MWH ceased distributing products for Tega on 31 January 2020. MWH itself admits this in its first affidavit [see paragraph 6, page 7, E.2]. This means Version 4 was never distributed by MWH. 20! ! [41] MWH has also repeatedly acknowledged that Version 4 was manufactured by Farmasia, which had nothing to do with the matters at trial in Suit 15 [see paragraphs 21 and 22 of MWH’s first affidavit, pages 27 to 29, E.2]. This then only means Farmasia had nothing to do with Versions 1, 2, or 3 and played no part in their manufacture. [42] No issue was ever raised or pleaded by MWH during the trial of Suit 15 regarding Version 4 or the involvement of products manufactured by Farmasia in the matters raised in Suit 15. The only probable conclusion is that the MDA Notice, on its face, is an administrative recall directive issued in respect of Version 4. It does not mention Versions 1–3. There is no suggestion that the MDA has ever issued any similar recall regarding Versions 1–3 or that the MDA had any regulatory oversight over those earlier products. [43] MWH nevertheless advances several links from the MDA Notice (Version 4) to Versions 1–3. For the reasons that follow, I find these arguments unpersuasive. [44] Foremost, Tega had no legal duty in Suit 15 to volunteer the MDA Notice, as I have alluded to in paragraphs 42 and 43 of this judgment. The notice concerned a different product, manufactured by a different entity, and subject to a different regulatory regime. Version 4 was never pleaded; indeed, MWH expressly acknowledged in its own affidavit that Version 4 was produced by Farmasia and was not part of the products it had distributed. 21! ! [45] MWH contends that the MDA Notice, which references a manufacturing and distribution period commencing in August 2019, applies retrospectively to product Versions 2 and 3. This reasoning conflates two distinct matters: the temporal scope of the distribution of contaminated Version 4 products, and the specific product versions subject to the recall. The MDA Notice explicitly identifies the recalled product as "OGE Bio-Aqacel Moisturising Mineral Water" in its Version 4 formulation and registration. The reference to August 2019 indicates the commencement of the manufacturing period for Version 4 products bearing that specific formulation; it does not apply to earlier versions. Critically, no evidence suggests that the MDA’s findings regarding Version 4 apply retrospectively to the materially different formulations of Versions 1 through 3. [46] MWH further argued that because all versions contain germanium, the MDA Notice’s findings on "undeclared germanium" must apply to all versions. With respect, this argument oversimplifies the regulatory framework. The Notice pertains specifically to Version 4, which was registered as a medical device. The core issue was not merely the presence of germanium, but its undeclared status within the medical device registration, the specific formulation and concentration present in Version 4, and its compliance with medical device regulations. In contrast, Versions 1–3 were regulated as cosmetic products, subject to entirely different regulatory requirements. The mere presence of germanium as an ingredient does not ipso facto mean all versions are contaminated, nor does it justify extrapolating findings from one version to all others. 22! ! [47] MWH also pointed to Tega’s marketing description of Version 4 as a "repackaging" of Version 3, inferring they are the same product. However, marketing descriptions do not govern legal and regulatory classification. The substantive change in Version 4 was its registration as a medical device, which brought it under a distinct regulatory regime with different oversight and requirements. The MDA Notice itself treats Version 4 as a distinct, registered medical device. If Versions 3 and 4 were truly identical, there would have been no need for Tega to separately register Version 4 as a medical device at all. [48] MWH submitted that Tega’s claim for damages in Suit 15 covers the period from December 2019 to 12 March 2024—a period during which Version 4 was predominantly distributed—and therefore Version 4 was implicitly part of the suit. This argument is with respect, misconceived. The damages claimed in Suit 15 relate to the passing off established by MWH’s distribution of 2,000 samples using Tega’s forms (which occurred in late 2019/early 2020), unlawful interference with trade by MWH and Heidi, and the continuing effects of these wrongful acts on Tega’s business. The extended damages period reflects a claim for continuing loss flowing from MWH’s wrongful acts, not an implicit inclusion of Version 4 within the liability findings. The liability issues in Suit 15 were determined based on the pleaded case concerning Versions 1–3. Any assessment of damages would require proof of causation stemming from those wrongful acts. In any event, assessment of damages is a separate proceeding; MWH cannot use the pleaded damages period to retroactively expand the scope of the liability. 23! ! [49] Even assuming, for the sake of argument, that the MDA Notice were relevant—which I have definitively found it is not—it does not establish what MWH claimed and utterly failed to prove at trial: namely, that Versions 1–3 were contaminated. The contamination issue at trial concerned MWH’s specific allegations that particular batches of Version 3 (Batch 42) delivered to MWH were contaminated, that this contamination justified MWH’s recall actions, and that Tega’s products posed safety risks. [50] The court’s findings were based on MWH’s failure to call the makers of laboratory certificates to testify, Tega’s expert evidence indicating no contamination, and the credibility of the competing evidence. The MDA Notice regarding Version 4 and undeclared germanium in its medical device registration does not prove or disprove contamination of the specific Version 3 Batch 42 that was the subject of trial. To reiterate my views aforesaid, these involve different products, different regulatory contexts, and different factual issues. MWH’s attempt to introduce this evidence is a transparent attempt to relitigate settled issues and is wholly without merit. [51] For these reasons, I find that Tega had no duty to disclose the MDA Notice during the trial in Suit 15. First, as extensively discussed, the Notice concerned Version 4, which was not part of the pleadings, evidence, or issues in Suit 15. A party’s duty to disclose is circumscribed by relevance; Tega cannot be faulted for failing to disclose a document relating to a product that was not in issue. [52] Second, the burden of proof rested on MWH. In Suit 15, MWH bore the burden of proving contamination as part of its defence and 24! ! counterclaim. By analogy, MWH, as the party asserting contamination, needed to prove it. Tega’s role was to respond to and test that evidence. The burden was not on Tega to discharge MWH’s own obligation to prove contamination. Had MWH failed to adduce sufficient evidence, its claim would have failed irrespective of what Tega did or did not produce. [53] Third, MWH had equal access to the information. The MDA Notice was issued by a public regulatory authority, and such notices are publicly available on the MDA website. MWH, as a party vitally interested in proving contamination, had the means and opportunity to monitor MDA announcements, search public registers, and investigate regulatory actions concerning Tega’s products. MWH cannot now claim to have been deprived of evidence that was publicly accessible to it. [54] Fourth, MWH’s own conduct negates any suggestion of fraud. Learned counsel for Tega submitted, and I accept, that MWH knew or should have known about potential regulatory issues concerning Tega’s products because MWH itself had raised contamination allegations, was familiar with the product line, and had every incentive to investigate regulatory matters to support its case. If MWH was genuinely unaware of the MDA Notice during the trial— which concluded on 24 October 2023, two months after the Notice was issued—this reflects MWH’s own failure to conduct reasonable inquiries, not any fraud by Tega. 25! ! [55] What section 44 of the EA 1950 demands is a breach of a legal duty coupled with malus animus. That threshold is not crossed where (i) Version 4 fell outside the pleaded frame, (ii) the principal issues tried concerned passing off and interference, and (iii) MWH itself knew of the Notice during the trial. [56] To characterise Tega’s non-disclosure of the MDA Notice – which related to a non-pleaded, later product – as “fraud” within the meaning of s 44 would be to stretch that concept beyond recognition. As Yow Man Kong makes plain, a party is not under a duty in earlier proceedings to volunteer material relating to issues that were never raised on the pleadings. [57] In Yow Man Kong the Court of Appeal held: [56] From the reading of para [169] above, it is obvious to us that the learned JC had misconstrued the concept of fraud in s 44. His understanding of fraud is the appellant did not tell the truth that the impugned transaction is illegal moneylending. We had to say his decision is seriously wrong for the following reasons. Firstly, it is in direct contravention to the basic rule of pleadings ie not only parties are bound by their pleadings, but the court also is not entitled to decide on a matter on which no issue has been raised by the parties (see Janagi v Ong Boon Kiat [1971] 2 MLJ 196). At the risk of repetition, the appellant’s case in the sessions court is not moneylending. His case is the impugned transaction is genuine as what the documents say. Moneylending is a non-issue in that suit. Therefore, it is erroneous for the learned JC to hold the appellant had to tell the truth to the sessions court about issue that not only do not exist and at the same time the parties never asked the court to decide. Further, 26! ! as rightly submitted by counsel for the appellant why should the appellant assist the respondents. It would be self defeating to him. [57] Secondly, on the point of pleadings, the respondents’ case of concealment of illegality or fraud against the appellant could not stand. Therefore, the present suit is simply a case of the respondents’ failure to plead illegality in the earlier suit, but putting the blame on the appellant. [58] Thirdly, the learned JC had misunderstood that the burden to proof fraud is on the respondents, not the appellant. In this case, we find the learned JC did not make any finding whether the respondents have proved the appellant had committed actual fraud upon the court in the earlier proceedings in the sense the appellant had fraudulently influenced the decision-making process of the court in granting summary judgment. In the absence of such finding, the court was wrong in setting aside the previous judgment in Suit 510. On this ground alone, we agree with counsel for the appellant that this appeal ought to be allowed. [Emphasis is ours] [58] The position is further complicated by the fact—which MWH candidly admits—that it became aware of the MDA Notice in October 2023, while Suit 15 was ongoing and months before the Judgment was rendered. [59] MWH seeks to place the responsibility for the non-disclosure solely on Tega, suggesting that Tega had a higher duty of candour as the plaintiff in Suit 15 and as the registrant of Version 4. However, the question under s 44 is whether the successful party procured the judgment by its own fraud. It is not open to a losing party, which was itself aware of the supposed “critical” evidence and chose not to deploy it, to impeach the judgment by pointing to the other side’s equal non-disclosure. 27! ! [60] Learned counsel for Tega has, with some force, suggested reasons why MWH may have elected not to rely on the MDA Notice during the trial. As learned counsel points out, MWH and Heidi maintained counterclaims which proceeded on the premise that Tega’s products were marketable and that MWH had suffered a loss of profits when it was no longer able to sell them, and that Heidi was entitled to royalties and other payments for the formula allegedly used to manufacture those products. Hence, had MWH made this radical proclamation in Suit 15, it would have hindered its own counterclaim and Heidi’s counterclaim. [61] I do not need to make any definitive finding on MWH’s motives. It suffices to note that the record reveals no deliberate stratagem by Tega to keep MWH in ignorance of the MDA Notice. To the contrary, MWH acknowledges knowing of the Notice and yet deciding not to rely on it. In these circumstances, it is difficult to see how Tega can be said to have "by its fraud" prevented MWH from presenting its case. [62] In my judgment, the combination of (a) the absence of any pleading or issue in Suit 15 relating to Version 4, and (b) MWH’s own admitted knowledge of the MDA Notice during the trial, is fatal to the contention that Tega’s non-disclosure of the Notice constituted “actual positive fraud” within the meaning of s 44. [63] MWH was not prevented by any conduct of Tega from placing the Recall Notice before the Judge. If MWH wished to rely on it, 28! ! procedural avenues to seek leave to reopen or adduce additional evidence were available. That reality significantly weakens any suggestion that Tega “kept MWH and the court in ignorance.” [64] For completeness, I add that even leaving aside the questions of duty and knowledge, MWH has not adduced cogent evidence that Tega acted with a dishonest intent to deceive the Court. [65] Much of MWH’s case consists of assertions and inferences that Tega “must have known” that the MDA Notice undermined its case in Suit 15, and that its failure to disclose it must therefore have been fraudulent. But s 44 demands more than suspicion or conjecture. As the Privy Council observed in Satish Chandra Chatterji, allegations of fraud must be proved “by established facts or inferences legitimately drawn” therefrom; “suspicions and surmises and conjecture are not permissible substitutes”. [66] Here, there is no direct evidence that Tega deliberately concealed the MDA Notice with the intention of deceiving either the Court or MWH. Nor is there any coherent explanation from MWH as to how Tega’s supposed knowledge of Version 4’s recall could be said to falsify the evidence that Tega led in Suit 15 concerning the development, composition, and testing of Versions 1–3. [67] In my view, the evidence falls well short of establishing the sort of deliberate, targeted deception that the authorities require. The allegation of fraud is therefore not made out. 29! ! [68] Even if I were prepared to assume, contrary to my earlier conclusions, that Tega ought to have drawn the MDA Notice to the Court’s attention, that would not, without more, justify impeaching the Judgment. The applicant under s 44 of the EA 1950 must also demonstrate that the suppressed material was such that, if it had been disclosed, it would have been reasonably likely to lead to a different outcome. [69] In this respect, MWH’s case encounters several serious difficulties. [70] As I have already noted, Suit 15 was confined to Versions 1–3. Version 4 was never pleaded, never sold by MWH, and was never part of the factual matrix before the Court. [71] MWH is now contending that the contamination was not caused by bacteria or yeast but was caused by the inclusion of “Germanium.” MWH’s contention effectively means that, as all of Tega’s Products—namely, Version 1, Version 2, and Version 3—contained “Organic Germanium,” this contamination would have been present from the very start, affecting every single customer that had ever purchased or used Version 1, Version 2, or Version 3 since 2017. [72] This Court in Suit 15 was therefore not required – and, indeed, would not have been entitled – to make findings concerning Version 4 or products manufactured by Farmasia. To suggest that an administrative recall of Version 4 in August 2023 would have compelled the Court to revisit its findings on liability and goodwill in respect of Versions 1–3, based on events that occurred between 2017 and early 2020, is a speculative proposition. 30! ! [73] Learned counsel for MWH effectively asks this Court to proceed on the basis that a recall affecting Version 4 in 2023 necessarily implies that Versions 1–3 were contaminated from their inception, and that Tega’s goodwill was a mere façade. This is not the case that MWH presented at trial; it is a radically new hypothesis constructed ex post facto around the MDA Notice. [74] To permit such a reconstruction of the factual and legal landscape of Suit 15 based on a regulatory notice directed at a later, different product would be difficult to reconcile with the principles of finality and the pleaded case. [75] More fundamentally, MWH’s case assumes that Suit 15 was decided on the premise that Tega’s products were entirely free from any contamination concerns, and that the MDA Notice would have upended that premise. That is not an accurate characterisation of the Judgment. [76] The earlier judgment of this Court, as summarised in Tega’s submissions, rested on multiple, independent pillars: Tega’s development and ownership of the Bio-Aquacel marks and products; MWH’s role as distributor and its access to Tega’s confidential know-how and market; the post-termination collaboration between MWH and Heidi to develop and sell a competing product using a substantially similar formula; the misrepresentation of products to customers and sub-distributors; and the resulting damage to Tega’s goodwill and trade. 31! ! [77] The issue of contamination was raised primarily in the context of MWH’s counterclaim, where it asserted that Tega’s products were contaminated and that Tega’s goodwill had been destroyed. The Court rejected that counterclaim, finding, inter alia, that not all customers had complained of contamination, that Tega’s goodwill had not been extinguished, and that MWH had in fact benefited substantially from the distribution of Tega’s products over several years. [78] Even if the MDA Notice had been placed before the Court, it would not, in my judgment, have compelled the conclusion that Versions 1–3 were unsafe or that Tega had no protectable goodwill. There would have remained substantial evidence of market acceptance, brand recognition, and commercial success, as well as the independent wrongs of misappropriation and passing off, which do not depend on the integrity of the plaintiff’s product. [79] In other words, the Judgment does not hinge on a binary proposition: that Tega's products were either entirely uncontaminated (in which case Tega wins) or inherently unsafe (in which case Tega must lose). Rather, it rests on a more nuanced assessment of the parties' conduct, the state of the market, and the scope of the misrepresentations. The MDA Notice, even if admitted, would have, at most, added a complication to the contamination narrative; it would not have dismantled the foundation of Tega's claims. 32! ! [80] In my view, MWH has not demonstrated that the MDA Notice, had it been disclosed, would have made it reasonably probable that the outcome in Suit 15 would have been different. On this basis too, the application fails. I find that on the totality of the evidence, the Recall Notice does not carry decisive probative weight. b) Whether this is an appropriate and proportionate case to invoke the exceptional jurisdiction under s 44 to impeach a judgment [81] Based on the reasons I have alluded to in the preceding paragraphs, I agree with learned counsel for Tega that the instant proceedings amount to a collateral attack on the Judgment and an abuse of process. [82] Critically, even if the MDA Notice had been before the court, I am satisfied that it would not have altered the finding that MWH failed to prove contamination of Versions 1–3. The court’s analysis was based on MWH’s failure to properly prove its case through admissible evidence, the credibility of Tega’s expert evidence on the specific batches tested, and the inadequacy of MWH’s documentation and witnesses. A regulatory notice concerning a different product—Version 4, registered under a different regulatory regime as a medical device rather than a cosmetic—would not have remedied these evidential deficiencies. The MDA Notice states the recall reason as “undeclared raw material (Germanium)” in a medical device. This is a regulatory compliance issue, not proof of microbiological contamination or unsafety, which was the pleaded case. “Undeclared” does not equate to “contaminated” in the sense 33! ! MWH alleged; it signifies non-compliance with registration requirements. Therefore, the MDA Notice, even if admitted, would not have been determinative of the contamination issue as tried. [83] Learned counsel for MWH argued that the MDA Notice undermines Tega’s goodwill and reputation, which was essential to the passing! off claim. I disagree for several reasons. First, the passing-off finding was based primarily on MWH’s misrepresentation through its use of Tega’s delivery forms, not solely on the strength of Tega’s goodwill. As noted at paragraph 60 of the earlier Grounds of Judgment of this Court, the distribution of 2,000 free samples of MWH Bio-Aquacell to the public constituted a misrepresentation of association. That misrepresentation was made out regardless of the extent of Tega’s goodwill. Second, goodwill in Versions 1–3—the products actually in issue—is not automatically destroyed by a later regulatory issue concerning Version 4, a different product. Third, Tega’s products enjoyed substantial market presence and sales during the relevant period (2017–2020), as established at trial; this goodwill related specifically to Versions 1–3. Fourth, a single regulatory recall notice does not necessarily extinguish all goodwill in a business; many enterprises experience product recalls while retaining customer trust. [84] To impeach the judgment, MWH must establish actual positive fraud—an intentional, deliberate act to deceive the court. With respect, MWH has failed to do so. There was no intentional deception: at most, MWH has shown that Tega did not volunteer information about Version 4, which is not the same as deliberately deceiving the court about matters actually in issue. No duty was 34! ! breached, as Tega had no obligation to disclose a notice relating to a non-pleaded product. MWH does not allege that Tega presented false evidence or lied to the court; Tega’s expert witnesses testified truthfully regarding their testing of Version 3. There was no suppression of relevant documents, because the MDA Notice was not relevant to the issues pleaded and tried in Suit 15. [85] Learned counsel for Tega submitted that MWH is impermissibly approbating and reprobating by accepting the dismissal of the trademark-infringement claim while seeking to impeach only the findings on passing off and unlawful interference. While MWH is technically only challenging parts of the judgment, there is force in learned counsel’s submission that MWH’s approach is opportunistic. MWH lost at trial on its contamination defence after a full hearing where it had every opportunity to prove its case. It lost its counterclaim for refunds and damages based on alleged contamination. Now, nearly nine months after the judgment, MWH seeks a second bite at the cherry by introducing new evidence—the MDA Notice—which it could have discovered and presented at trial. This is precisely the type of collateral attack on final judgments that the strict rules on impeachment are designed to prevent. [86] While MWH filed this originating summons relatively promptly after engaging new solicitors, the delay from the MDA Notice (24 August 2023) to this application (26 December 2024) requires explanation. Learned counsel for MWH argued that his client only became aware of the Notice after engaging new solicitors. However, the Notice was issued during the trial—specifically after the fifth day of trial and before five subsequent trial dates. To reiterate my views, as an 35! ! interested party actively disputing contamination issues, MWH had every incentive and opportunity to monitor regulatory developments, check public MDA records, and investigate Tega’s compliance status. Its failure to discover publicly available information for over a year does not constitute fraud by Tega. The delay undermines MWH’s case: if the MDA Notice were truly as critical and obvious as MWH now claims, it should have been discovered much earlier. [87] The findings in Suit 15 established that MWH collaborated with Heidi (Tega’s former director) to create a rival product, distributed samples while still Tega’s master distributor, used Tega’s own forms to distribute the rival product, and created a misrepresentation of association with Tega’s products. These findings stand independently of any contamination issue and independently of the MDA Notice. As noted at paragraph 61 of the Grounds of Judgment, MWH’s conduct was aggravated by the fact that it distributed MW Bio-Aquacell while still operating as Tega’s master distributor. Nothing in the MDA Notice changes or excuses MWH’s wrongful conduct as found by the court. MWH cannot use the impeachment process to escape liability for its own established wrongdoing. [88] It is well established that s 44 of the EA 1950 is not to be used as a vehicle for relitigating issues that could and should have been raised in the original proceedings. It is an abuse of process to raise in subsequent proceedings matters that were open to a party in earlier proceedings but were not then pursued; parties are bound by their pleadings and by the forensic choices they make. 36! ! [89] In the present case, MWH was aware of the MDA Notice before the conclusion of the trial in Suit 15. If it genuinely considered the Notice to be as critical and transformative as it now claims, the proper course would have been to seek to adduce it in Suit 15 – whether by recalling witnesses, applying for leave to adduce further evidence, or seeking an adjournment to address its implications. [90] Instead, MWH did none of these things. It allowed the trial to conclude, awaited the Judgment, and only many months later sought to impeach the Judgment via a fresh action premised on a new contamination theory that was never ventilated at trial and which sits uncomfortably with its own past and present commercial conduct. [91] While my decision does not rest solely on abuse of process, these features reinforce my conclusion that this case does not engage the exceptional jurisdiction under s 44 of the EA 1950. To permit the Judgment to be reopened in these circumstances would be to dilute, in a most unwarranted way, the principle of finality in litigation and to encourage disappointed litigants to recast decisions as “fraud” whenever fresh material emerges. [92] In Seng Huat Hang (supra) the Court held at page 421: Now, a party cannot, in a subsequent action, raise a ground of claim or defence which, upon the pleadings, was open to him in the former one. Thus, in an action for arrears of rent, where a defendant unsuccessfully pleaded no concluded agreement, he was prevented in a subsequent action for further arrears of rent, from setting up the further defence under the Statute of Fraud of no memorandum in writing: Humphries v Humphries [1910] 2 KB 531. 37! !
