Summary
In Ser Kang Wei (Xu Kangwei) & Anor v Salas Porras Carlos Luis & 2 Ors ([2025] SGHC 257), the High Court dealt with a procedural challenge to a worldwide Mareva injunction (“ORC 4167”) granted ex parte in support of a substantive claim in HC/OC 545/2025. The second and third defendants, Mark and Emily, applied in HC/SUM 2924/2025 to set aside ORC 4167, arguing that the claimants had not shown a good arguable case and that there was no real risk of dissipation of assets. They also sought, in the alternative, to vary the injunction to increase the amount they were allowed to spend on ordinary living expenses and to require the claimants to fortify their undertaking as to damages.
The court dismissed the application to set aside ORC 4167. However, it ordered the claimants to fortify their undertaking as to damages by paying $100,000 into court. The decision is significant for practitioners because it reiterates the structured approach Singapore courts take when assessing (i) whether a Mareva injunction “encapsulates” the statutory foundation under the Rules of Court, (ii) whether there is a sufficient legal and factual basis for a “good arguable case”, (iii) whether there is a real risk of dissipation, and (iv) whether the claimant’s disclosure and use of interlocutory processes amount to abuse. The court’s willingness to maintain the injunction while still requiring fortification underscores that even where a Mareva injunction is upheld, the court may impose additional safeguards to protect the restrained party.
What Were the Facts of This Case?
The dispute arose out of alleged fraudulent gold investment schemes. The claimants, Ser Kang Wei (“Jack”) and Lucent Trading Limited (“Lucent Trading”), sued the defendants for misrepresentation, conspiracy, and unjust enrichment, seeking recovery of both principal sums and promised profits. The Mareva injunction ORC 4167 was granted on 21 July 2025 following an ex parte application by the claimants in SUM 1957. ORC 4167 prohibited Mark, Emily, and Carlos from disposing of assets worldwide up to a total value of US$38,614,846, while permitting limited expenditure for ordinary living expenses (including $1,000 per week).
The factual background was complex and hotly contested, with three competing narratives advanced by (a) the claimants, (b) Carlos, and (c) Mark and Emily. According to the claimants’ account, around March 2019 Carlos enticed Jack to invest in a South African gold trading arrangement. The claimants described a structure involving licensed refineries and trading intermediaries: Ultra Trading 014 (Pty) Ltd (“Ultra Trading”) would consolidate gold from small artisanal miners and sell it to Precious Metals Tswane (Pty) Ltd (“Precious Metals SA”), a registered gold refinery. Precious Metals SA was said to be owned by Patrick Chinondo (“Patrick”). Profits would be shared with investors under what the claimants called the “SA Scheme”.
Jack’s investment into the SA Scheme was said to occur through cryptocurrency transfers of Tether (“USDT”). The claimants alleged two transfers totalling US$2,759,534 to a crypto wallet controlled by Carlos on 31 October 2019 and 9 November 2019. Later, Carlos proposed formalising the investment through a fund called PIERCE50, described as the flagship fund of Coinful Capital Fund SPC (“Coinful Capital”), a hedge fund set up in the Cayman Islands in 2018. Jack agreed for his investment to be transferred to Coinful Capital around 5 January 2020.
As the SA Scheme allegedly progressed, Jack sought to increase his investment. Carlos suggested investing through a BVI company, Master Dragon Global Enterprises Holding Ltd (“Master Dragon”), purportedly to secure higher returns because it was “unregulated” and would not incur regulatory fees. The claimants alleged that Mark was involved in Master Dragon from the outset, and that Mark’s shareholding in Master Dragon had only been transferred to Carlos on 15 April 2020, implying that Mark had earlier control or influence. Between 5 February 2020 and 21 September 2021, the claimants asserted that Jack invested a further US$35,855,312 with Master Dragon through Lucent Trading. The judgment notes minor inconsistencies in the pleaded amount across documents, but proceeds on the pleaded figure for simplicity.
In late 2021, Carlos allegedly informed Jack that COVID-19 had created difficulties in South Africa, and that a similar scheme could be executed in Zimbabwe. Under the “Zimbabwean Scheme”, BetterBrands Investments (Private) Limited (“BetterBrands Investments”) would purchase gold and sell it to Fidelity Printers and Refiners (“Fidelity”) for a profit, with profits shared with investors. Jack was said to believe BetterBrands Investments was part of the BetterBrands Jewellery Group, a Zimbabwean conglomerate founded by Scott Sakupwanya, and that Fidelity was wholly owned by the Reserve Bank of Zimbabwe. The claimants’ case, however, was that BetterBrands Investments was a separate entity with no relation to the BetterBrands Jewellery Group.
After October 2021, Jack allegedly stopped receiving interest payouts. In January and February 2022, Carlos explained that Fidelity had received the gold but could not export it due to COVID-19, preventing payment. Carlos shared a letter dated 11 February 2022 in which Fidelity confirmed it was holding 1,508.47kg of BetterBrands Investments’ gold. Carlos also allegedly shared a Master Sale and Purchase Offtake and Underwriting Agreement to evidence the Zimbabwean transactions. On 17 April 2022, Jack travelled to Zimbabwe and stayed at Mark’s and Emily’s house with Carlos. During a meeting with all parties present, Jack allegedly learned for the first time that Mark had been involved in both the SA and Zimbabwean schemes from the outset. Jack further attempted to engage with the Governor of the Reserve Bank of Zimbabwe, but only met the Governor briefly.
What Were the Key Legal Issues?
The court identified several discrete issues to determine in SUM 2924. The first was whether the Mareva injunction “encapsulated” in ORC 4167 should be set aside. This required the court to consider the legal foundation for granting Mareva injunctions in Singapore and whether the injunction properly reflected the governing procedural and substantive principles.
Second, the court had to assess whether the claimants had a “good arguable case” against Mark and Emily. This is a threshold requirement in Mareva applications: the claimant need not prove its case at trial, but must show that there is a serious question to be tried and that the claim is not frivolous or vexatious. In this case, the analysis turned on the alleged roles of Mark and Emily in the SA and Zimbabwean schemes, including their involvement in Master Dragon and the flow of funds.
Third, the court had to decide whether the claimants had shown a “real risk” that Mark and Emily would dissipate assets. Mareva relief is protective and preventative; it is not granted merely because a defendant is alleged to have acted fraudulently. The claimant must show risk of dissipation, assessed in light of the evidence and the circumstances.
Fourth, the court addressed whether the claimants failed to make full and frank disclosure in SUM 1957, and whether SUM 1957 was an abuse of the court’s process. Mark and Emily argued that the claimants used ORC 4167 to coerce a witness (Gloria) into testifying against them, and that ORC 4167 was “weaponised” to extract information about their assets.
Finally, the court considered whether ORC 4167 should be varied to increase the amount Mark and Emily were permitted to spend on ordinary living expenses, and whether the claimants should be ordered to fortify their undertaking as to damages.
How Did the Court Analyse the Issues?
The court began by setting out the procedural background and the nature of the Mareva injunction. ORC 4167 was granted ex parte in support of OC 545. The judge emphasised that Mareva injunctions are exceptional remedies because they restrain a defendant’s dealings with assets without a prior inter partes hearing. Accordingly, the court’s approach is structured: it examines the legal basis for the injunction, the claimant’s arguable case, the risk of dissipation, the quality of disclosure, and any alleged abuse of process. This framework ensures that the injunction is not used as a tactical tool but remains anchored in the protective purpose of Mareva relief.
On the question whether the Mareva injunction “encapsulated” in ORC 4167 should be set aside, the court treated the issue as one of legal foundation and procedural propriety. While the judgment extract provided does not reproduce the full analysis, the headings indicate that the court considered whether the injunction properly reflected the statutory and rule-based basis for Mareva relief. The court’s ultimate decision to dismiss the set-aside application suggests that it found the procedural foundation adequate and that the injunction met the threshold requirements for continuing effect, subject to the court’s additional safeguard order on fortification.
Turning to the “good arguable case” requirement, the court examined the claimants’ narrative about the alleged fraudulent schemes and, crucially, the alleged roles of Mark and Emily. The judge referred to the claimants’ account that Mark was involved in Master Dragon from the outset, and that Mark and Emily were connected to both the SA Scheme and the Zimbabwean Scheme. The court also noted that the factual disputes would be determined at trial, but the Mareva stage requires only that the claimants demonstrate a serious question to be tried. The court’s dismissal of the set-aside application indicates that it was satisfied that the claimants’ case against Mark and Emily was not merely speculative.
On the “real risk of dissipation” issue, the court assessed whether the evidence supported a concern that Mark and Emily would move assets to frustrate enforcement. Mareva jurisprudence typically looks at factors such as the defendant’s conduct, the nature of the assets, the defendant’s financial situation, and any indications of intent to evade. In this case, the court’s decision to maintain ORC 4167 implies that the risk threshold was met on the evidence before the court, even though the underlying facts were contested.
The court then addressed disclosure and abuse of process. The headings show that the judge considered whether there was undue delay in filing SUM 1957, whether the claimants used ORC 4167 to coerce Gloria into testifying against Mark and Emily, and whether the claimants “weaponised” ORC 4167 to extract information about their assets. The fact that the court dismissed SUM 2924 on the set-aside limb suggests that it did not find the alleged disclosure failures or abuse to be sufficient to undo the injunction. However, the court’s order for fortification indicates that it still considered there to be a need for enhanced protection for the restrained parties, likely reflecting concerns about the balance of prejudice.
Finally, the court considered variation of the injunction. Mark and Emily sought to increase the quantum they could spend on ordinary living expenses, arguing that maintaining the existing cap would unjustly compel them to lower their standard of living. The court’s dismissal of the variation request (as reflected by the “save for the issue of fortification” outcome) indicates that it was not persuaded that the existing allowance was inappropriate. Courts often allow limited living expenses to avoid undue hardship, but they remain cautious not to undermine the protective purpose of the Mareva order.
As to fortification, the court ordered the claimants to pay $100,000 into court. This reflects a balancing exercise: while the injunction remains in place, the court mitigates the risk of injustice to the defendants if the claimants ultimately fail to establish liability. Fortification is a practical safeguard that can be ordered where the court considers it appropriate in the circumstances, particularly where the ex parte nature of the order and the potential for prejudice warrant additional security.
What Was the Outcome?
The High Court dismissed HC/SUM 2924/2025, thereby refusing to set aside ORC 4167 and refusing to vary the injunction to increase the defendants’ ordinary living expenses allowance. The Mareva injunction therefore continued to restrain Mark and Emily from disposing of assets worldwide up to the specified value.
However, the court ordered fortification: the claimants were directed to pay $100,000 into court as security for their undertaking as to damages. This outcome maintained the protective effect of the Mareva injunction while addressing concerns about potential prejudice to the restrained parties.
Why Does This Case Matter?
This decision is important for practitioners because it illustrates how Singapore courts handle challenges to Mareva injunctions at the interlocutory stage. The court reaffirmed that a defendant seeking to set aside a Mareva injunction faces a significant threshold. Even where the underlying facts are contested and the case will be determined at trial, the court will generally uphold the injunction if the claimant demonstrates a good arguable case and a real risk of dissipation.
Equally, the case highlights that ex parte Mareva relief is not “set and forget”. The court scrutinised disclosure and alleged abuse of process, including arguments that the injunction was used to coerce testimony or to extract asset information. While these arguments did not succeed in setting aside the injunction, the court’s response—ordering fortification—demonstrates that the court may still impose remedial measures to protect the restrained party.
For lawyers advising clients in fraud and asset-tracing disputes, the judgment underscores the practical importance of (i) presenting a coherent and credible arguable case against specific defendants, (ii) adducing evidence supporting risk of dissipation, (iii) ensuring full and frank disclosure in ex parte applications, and (iv) anticipating that even if the injunction is upheld, the court may require additional security through fortification. The decision also serves as a reminder that applications to vary Mareva terms (such as living expense allowances) will be assessed through the lens of proportionality and the need to preserve the injunction’s effectiveness.
