Summary
This Court of Appeal decision concerns security for costs (“SFC”) in civil litigation and, more specifically, the principles governing the form of SFC that a court may accept. The dispute arose in Suit 267 of 2022, where the appellant, Ms Lum, sought SFC for her costs up to the filing and/or exchange of affidavits of evidence-in-chief. The respondents—companies in insolvency-related processes and their liquidators/receivers—agreed to provide SFC in the agreed quantum of $90,000 but could not agree on the form.
The High Court (in Registrar’s Appeal No 42 of 2023) accepted a “joint undertaking” offered by the respondents’ litigation funder’s parent company and its Singapore-incorporated subsidiary, and ordered that this undertaking be treated as adequate security. Ms Lum then sought permission to appeal, and the Appellate Division granted permission on two questions of general principle: (i) what principles apply in determining the appropriate form of SFC, and (ii) whether those principles should be as stated in DIF III Global Co-Investment Fund, L.P. v BBLP LLC & Ors (a decision of the Victorian Supreme Court).
On appeal to the Court of Appeal, a preliminary issue arose as to the scope of the permission granted by the Appellate Division. The Court of Appeal addressed how far the appeal could go beyond the two “permission questions”, and reaffirmed the wide discretion of the court to determine the form of SFC, subject to the protective purpose of SFC and the adequacy of the proposed security. The decision is therefore both procedural (concerning the scope of permission) and substantive (concerning the “mode” principles for assessing the adequacy of SFC forms).
What Were the Facts of This Case?
Ms Lum was the plaintiff/appellant in Suit 267 of 2022. The respondents were Hyflux Ltd (in compulsory liquidation), Hydrochem (S) Pte Ltd (in compulsory liquidation), and Tuaspring Pte Ltd (under receivership), together with two individuals, Cosimo Borrelli and Patrick Bance, who were the joint and several liquidators of Hyflux Ltd and Hydrochem (S) Pte Ltd. After the withdrawal of 33 other parties in 2022, the respondents remained as five plaintiffs in the suit.
The respondents were supported by litigation funding. Their litigation funder was Omni Bridgeway (Fund 5) Cayman Invt Ltd, a company incorporated in the Cayman Islands (“Omni Funder”). In the course of the proceedings, Ms Lum sought security for her costs for the period until the filing and/or exchange of affidavits of evidence-in-chief (“AEICs”). The quantum sought was $90,000. The respondents agreed to furnish SFC in that amount, but the parties could not agree on the form the security should take.
The matter came before Senior Assistant Registrar Cornie Ng (“SAR Ng”). On 14 February 2023, SAR Ng ordered that the respondents furnish $90,000 security for Ms Lum’s costs, with a staged hierarchy of acceptable forms: first, a costs undertaking jointly by Omni Bridgeway Limited and Omni Bridgeway (Singapore) Pte Ltd (collectively, the “Omni Related Companies”); if that was not acceptable, then a banker’s guarantee; if that was not acceptable, then a solicitor’s undertaking from the respondents’ lawyers; and if the parties could not agree on the terms of any of those undertakings, then payment into court. Pending provision of security, further proceedings were stayed (other than giving security), and Ms Lum was granted liberty to apply for further or subsequent security.
After SAR Ng’s order, the respondents appealed by way of Registrar’s Appeal No 42 of 2023 (“RA 42”). The High Court judge (“the Judge”) allowed the appeal and accepted the “Omni Undertaking” as adequate security, ordering that the respondents furnish security for Ms Lum’s costs up to the AEIC stage by way of the Omni Undertaking. Ms Lum then applied for permission to appeal. The Appellate Division granted permission in AD/OA 33/2023, framing two questions of law of general principle. The appeal was subsequently transferred to the Court of Appeal on the Court of Appeal’s own motion under the Supreme Court of Judicature Act 1969.
What Were the Key Legal Issues?
The first key issue was procedural: what was the scope of the permission to appeal granted by the Appellate Division? The Appellate Division had granted permission on two specific questions of law (the “PTA Questions”). The respondents argued that the appeal was confined to those questions, whereas Ms Lum contended that the scope was broader and permitted an assessment of the merits of the High Court judge’s decision beyond the strict confines of the PTA Questions.
The second key issue was substantive and concerned the principles governing the court’s discretion to accept and order the form of SFC. The High Court had adopted, as Singapore law, principles derived from DIF III, which emphasised (among other things) that the plaintiff is entitled to propose a form of security least disadvantageous to it, that the plaintiff bears a “practical onus” to show adequacy and absence of “unacceptable disadvantage”, and that the security must satisfy the protective object of SFC—namely, providing a fund or asset against which a successful defendant can readily enforce costs.
In particular, the appeal required the Court of Appeal to consider whether the “mode principles” synthesised by the High Court were correct and how they should be applied. The Court of Appeal also had to consider the extent to which the court’s discretion is constrained by any fixed framework, and whether conventional forms of security (such as payment into court or banker’s guarantees) should be preferred over alternative forms like costs undertakings by related entities.
How Did the Court Analyse the Issues?
The Court of Appeal began by setting out the procedural background and the nature of the High Court decision. It noted that RA 42 involved the court’s acceptance of a particular form of SFC: a joint undertaking given by the litigation funder’s parent company and its Singapore subsidiary. The High Court’s approach was grounded in the court’s powers under O 23 of the Rules of Court (Cap 322, 2014 Rev Ed), particularly the broad discretion to order security “in any form” the court deems fit.
On the preliminary issue of scope, the Court of Appeal addressed the effect of the Appellate Division’s grant of permission. Permission to appeal is not merely a formality; it delineates the issues that the appellate court is being asked to consider. The respondents’ position was that the Court of Appeal should confine itself to the two PTA Questions. Ms Lum’s position was that the permission should be read more expansively, allowing the Court of Appeal to evaluate whether the High Court judge had correctly applied the principles to the facts, and not merely answer abstract questions of law.
In resolving this, the Court of Appeal emphasised that the appellate court’s task is to decide the appeal properly within the boundaries of the permission granted, but that those boundaries may still permit a review of how the legal principles were applied. In other words, even where the permission is framed in terms of questions of general principle, the appellate court may still need to examine the High Court’s reasoning to determine whether the correct legal framework was used and whether it was applied consistently with the protective purpose of SFC. This approach ensures that permission questions are not treated as purely academic, detached from the practical outcome in the case.
Turning to the substantive analysis, the Court of Appeal explained that the High Court had adopted the DIF III principles as Singapore law and then synthesised them into two “Mode Principles”. The first mode principle is that the plaintiff is not restricted to any fixed form of SFC. The second is that the plaintiff bears the burden of showing that the proposed security is “adequate”, meaning that it provides a fund or asset against which a successful defendant can readily enforce an order for costs. The Court of Appeal accepted that these mode principles capture the essence of the court’s discretion and the protective function of SFC.
The Court of Appeal also endorsed the idea that the court’s discretion is “wide” and that SFC can take “infinite forms”. This is important because it means that the court should not treat traditional security mechanisms as presumptively superior. Instead, the court should focus on whether the proposed security achieves the protective object: ensuring that, if the plaintiff loses, the defendant can readily enforce a costs order. The adequacy inquiry is therefore practical and outcome-oriented, rather than formalistic.
Applying these principles to the facts, the High Court had found the Omni Undertaking adequate. The Court of Appeal reviewed the reasons given by the Judge. First, the undertaking was described as an irrevocable and unconditional promise to pay up to $90,000, making it akin to a bank guarantee. Second, the court was satisfied that the Omni Related Companies had sufficient assets to satisfy the costs order, noting that the quantum sought was relatively modest compared to their resources. Third, the court considered the reputational and commercial incentives for honouring the undertaking, which reduced the risk of non-performance.
Fourth, the court considered enforceability. Ms Lum would have immediate recourse against Omni Bridgeway (Singapore) Pte Ltd, which is based in Singapore. Even if enforcement against Omni Bridgeway Limited in Australia were required, Singapore judgments could be enforced in Australia with relative ease. Fifth, the undertaking included notification obligations relating to the litigation funding agreement, which further supported the reliability of the security arrangement. These factors collectively supported the conclusion that the proposed security did not impose an “unacceptable disadvantage” on the defendant and provided a readily enforceable fund or asset.
Finally, the Court of Appeal addressed the “conventional modes” point. The underlying concern in many SFC disputes is that alternative security arrangements might be less reliable, harder to enforce, or more speculative. The Court of Appeal clarified that while conventional forms may be familiar, they should not be automatically preferred. The correct approach is to assess adequacy in the particular circumstances, guided by the mode principles and the protective purpose of SFC.
What Was the Outcome?
The Court of Appeal upheld the High Court’s decision to accept the Omni Undertaking as adequate security for costs for the relevant period. In practical terms, this meant that Ms Lum’s costs up to the AEIC stage were secured not by payment into court or a banker’s guarantee, but by an undertaking given by the litigation funder’s parent and its Singapore subsidiary.
Additionally, the Court of Appeal addressed the scope of the permission to appeal and confirmed that the appellate review could properly consider whether the High Court had applied the correct legal framework and principles to the facts, while remaining anchored to the permission questions. The decision therefore provides both procedural guidance on how permission questions delimit an appeal and substantive guidance on how courts should evaluate the adequacy of non-traditional forms of SFC.
Why Does This Case Matter?
This case is significant for practitioners because it reinforces that Singapore courts have a wide discretion to order SFC “in any form” and that the adequacy of security is assessed by its practical enforceability and protective function, not by adherence to conventional security mechanisms. For plaintiffs and defendants alike, the decision clarifies that costs undertakings by litigation funders and related entities can, in appropriate circumstances, satisfy the protective object of SFC.
For litigation funders and insolvency-related litigants, the decision is particularly relevant. It demonstrates that courts may accept security structures that reflect modern funding arrangements, provided the undertaking is robust (eg, irrevocable and unconditional), backed by sufficient assets, and enforceable within a reasonable and workable legal framework. This reduces the risk that parties will be forced into more expensive or less commercially viable security formats.
For law students and litigators, the case also offers a useful framework for arguing SFC disputes. The “Mode Principles” distilled from DIF III—no fixed form restriction for the plaintiff, and a practical burden to show adequacy—provide a structured way to analyse whether a proposed security arrangement is sufficient. The Court of Appeal’s discussion of the scope of permission further underscores the importance of carefully framing appellate arguments in light of the questions of law granted by the Appellate Division.
