Summary
Foo Diana v Woo Mui Chan [2025] SGHC 125 is a High Court decision on costs arising from defamation proceedings. Although the plaintiff succeeded at trial and obtained damages, the court held that the plaintiff should not be awarded costs on the High Court scale. The plaintiff had commenced the action in the General Division of the High Court, but the damages ultimately awarded fell within the jurisdictional limit of the State Courts. Applying the default costs regime in s 39 of the State Courts Act 1970, the court found that the plaintiff had not established any relevant “sufficient reason” to justify bringing the claim in the High Court.
The court also emphasised that a litigant’s entitlement to vindicate rights is not without consequence. Where a party conducts litigation in an unreasonable manner, the party may still “win” on liability and damages, but the victory may be “Pyrrhic” once costs are assessed. In this case, the plaintiff’s claimed costs were found unjustified in amount and were reduced substantially by awarding costs on the Magistrate’s Court scale. The decision is therefore a cautionary example of how costs consequences can follow from forum selection and from pursuing costs that are disproportionate to the outcome.
What Were the Facts of This Case?
The dispute between Diana Foo (the plaintiff) and Woo Mui Chan (the defendant) arose out of online statements made by the defendant concerning the plaintiff. The parties had become acquainted in 2015 and later became friends, but their relationship soured and became litigious due to disagreements over loans extended by the plaintiff to the defendant. In 2018, the defendant posted an online review on the Google page of the Law Society of Singapore (“LSS”) relating to the plaintiff (“Statement 1”).
On 3 March 2020, the defendant also filed a written complaint to the LSS in respect of the plaintiff (“Statement 2”). The plaintiff sued the defendant for defamation in respect of both statements. The High Court first determined liability in Diana Foo v Woo Mui Chan [2023] SGHC 221 (“Diana Foo (Liability)”). Following that, the court conducted a separate assessment of damages, also before the same judge, in Diana Foo v Woo Mui Chan [2025] SGHC 54 (“Diana Foo (Assessment)”).
In the damages phase, the plaintiff sought general damages of $300,000 and at least $50,000 in aggravated damages. The court disagreed with the plaintiff’s valuation and awarded damages totalling $41,250, comprising general damages of $33,000 and aggravated damages of $8,250. Importantly for the later costs decision, the damages awarded were below the Magistrate’s Court limit of $60,000. This meant that, although the action was commenced in the General Division of the High Court, the eventual monetary outcome fell within State Courts jurisdiction.
After the damages judgment, the court directed the parties to file submissions on costs, including whether there was any reason why costs should not be assessed on the Magistrate’s Court scale. The plaintiff sought costs in the sum of about $175,268 (including disbursements). The defendant opposed, arguing that the plaintiff’s “public interest” framing did not justify High Court proceedings and that the costs claimed were unreasonable given the nature of the issues and the damages ultimately awarded. The High Court then delivered the present costs judgment.
What Were the Key Legal Issues?
The first key issue was forum-related: whether the plaintiff, having commenced the defamation action in the High Court, was entitled to costs on the High Court scale when the damages awarded were within the jurisdiction of the State Courts. This required the court to interpret and apply s 39 of the State Courts Act 1970, which sets a general rule that where a claim is commenced in the High Court but the damages awarded fall within State Courts jurisdiction, costs are ordinarily assessed on the applicable State Courts scale.
The second key issue concerned justification and proportionality of costs. Even if the plaintiff succeeded, the court had to decide whether the costs claimed were unreasonably incurred—particularly in light of the litigation’s complexity, the novelty (or lack thereof) of the issues, and the gap between the plaintiff’s claimed damages and the damages actually awarded. The court’s analysis therefore involved both statutory forum principles and the broader costs assessment logic that discourages disproportionate litigation expenditure.
Finally, the court had to address the plaintiff’s reliance on an exception to the default rule. The plaintiff argued that there was “sufficient reason” to bring the action in the High Court, drawing an analogy to another case where High Court costs were awarded despite damages falling within lower court jurisdiction. The court had to determine whether the plaintiff’s defamation claim genuinely raised the kind of sufficient reason contemplated by s 39(4)(a) of the State Courts Act.
How Did the Court Analyse the Issues?
The court began by setting out the costs framework and the policy rationale behind it. It noted that litigants may robustly vindicate rights, but the entitlement is not open-ended. Costs consequences can follow from unreasonable conduct. The judge linked this to professional duties of counsel, citing Rule 17(2)(e) of the Legal Profession (Professional Conduct) Rules 2015 and the Court of Appeal decision in Lock Han Chng Jonathan (Jonathan Luo Hancheng) v Goh Jessiline [2008] 2 SLR(R) 455 at [45]–[47]. The message was that lawyers must assist clients with an honest and realistic evaluation of prospects, including the likely costs consequences of pursuing a case in an inappropriate forum.
On the statutory question, the court accepted that the general practice under s 39(1) of the State Courts Act 1970 is to award costs on the applicable State Courts scale where the claim is commenced in the High Court but the damages awarded fall within State Courts jurisdiction. The judge also confirmed that there are four exceptions to this general rule, but only two were potentially relevant: (a) “sufficient reason” to bring the action in the High Court (s 39(4)(a)); and (d) where there was reasonable ground for supposing the amount recoverable would exceed what could be recovered in a State Court action (s 39(6)).
The plaintiff’s primary argument was that her defamation claim raised important public interest considerations, particularly concerning the integrity and reputation of legal professionals and the misuse of digital platforms for defamatory conduct. She also argued that the defendant had opportunities to resolve amicably but chose to mount an untenable defence of justification, and persisted even after a letter of demand. The plaintiff further relied on Shanmugam Kasiviswanathan v Lee Hsien Yang and another matter [2024] 5 SLR 194 (“Shanmugam”), where the court assessed costs on the High Court scale despite damages being within District Court jurisdiction, because it could reasonably be said that the case raised an important question of law concerning the court’s power to grant injunctive relief in a specific procedural context.
The High Court rejected the analogy. The judge found that there was no sufficient reason to bring the claim in the High Court. While the plaintiff contended that her case was “the first case of a lawyer being maligned on the internet,” the court noted that even if that contention could not be verified, there was nothing novel about lawyers being defamed or defamation occurring online. The court observed that Singapore has a substantial body of jurisprudence on online defamation, including the use of interaction levels to gauge publication extent. A case does not become novel merely because well-settled principles are applied together for the first time.
Turning to s 39(6), the court also found that there was no reasonable ground for supposing that damages likely to be recovered would exceed State Courts jurisdiction. The judge emphasised that an objective evaluation of the law would have revealed that damages within or near the High Court’s jurisdiction were not reasonably likely. Two aspects of the damages reasoning were particularly relevant. First, the plaintiff’s attempt to equate lawyers with public figures was misconceived. The court had previously held in the damages judgment that defamation of public figures should generally sound in greater damages than defamation of individuals. The plaintiff’s seniority at the Bar did not automatically confer the prominence associated with public figures, and the court had found no evidence that the plaintiff possessed a greater than ordinary reputation among advocates and solicitors in Singapore.
Second, the court noted that the plaintiff’s evidence of loss of earnings was “woefully short.” The plaintiff had claimed substantial losses from lost clients, but the court had characterised the support as general statements and sweeping assertions, with figures appearing to be pulled from thin air without adequate evidence. These findings undermined any argument that the plaintiff could reasonably expect damages above State Courts limits. In short, the court concluded that the plaintiff’s damages claim was not one that could realistically justify High Court proceedings under either s 39(4)(a) or s 39(6).
On the costs quantum, the court scrutinised the plaintiff’s claimed costs breakdown. The plaintiff’s total claim was $175,268, supported by attendance at numerous pre-trial conferences and summonses, substantial pleading and pre-trial work, and a five-day trial estimate. The court found the sum claimed unjustified and awarded significantly lower costs on the Magistrate’s Court scale. The decision reflects a practical approach: costs are not assessed solely by the number of steps taken, but by whether the steps were reasonably necessary and proportionate to the issues and likely outcome.
The court also addressed an evidential matter raised by the defendant: a letter from a prisoner remanded in Changi Prison, said to be a former client of the plaintiff, containing “input” on the plaintiff. The judge ignored the letter as vague, unverified, and irrelevant to the costs issues. This illustrates that costs submissions must remain anchored to relevant considerations, and that extraneous material will not influence the costs determination.
What Was the Outcome?
The High Court awarded the plaintiff costs assessed on the Magistrate’s Court scale rather than the High Court scale. The court found that the plaintiff had not established “sufficient reason” to bring the action in the High Court and had not shown any reasonable basis to suppose that recoverable damages would exceed State Courts jurisdiction. As a result, the plaintiff’s claimed costs of approximately $175,268 were reduced substantially.
Practically, the outcome means that even though the plaintiff succeeded on liability and obtained damages, the financial benefit of the win was diminished by the costs order. The decision underscores that forum selection and litigation strategy can materially affect the net recovery, particularly in defamation cases where damages may be difficult to predict and where the statutory costs regime can operate harshly against over-claiming or over-escalation.
Why Does This Case Matter?
Foo Diana v Woo Mui Chan is significant for practitioners because it reinforces the operation of s 39 of the State Courts Act 1970 as a default mechanism to prevent parties from “buying” High Court costs by commencing in the High Court when the eventual damages fall within State Courts jurisdiction. The case clarifies that arguments framed as “public interest” or “novelty” will not automatically satisfy the statutory exception. Courts will look at whether the case genuinely raises something sufficiently distinctive—such as an important question of law or a reasonably arguable basis for higher damages—rather than whether the claimant believes the subject matter is important.
For lawyers advising on defamation litigation, the decision also highlights the importance of realistic damages evaluation. The court’s reliance on its earlier findings in the damages judgment (including the treatment of public figure comparisons and the evidential weakness of claimed losses) demonstrates that costs outcomes can be driven by the same substantive assessments that determine damages. Counsel should therefore ensure that pleadings and litigation posture are aligned with the evidential record and with the likely damages range under established principles.
Finally, the decision serves as a professional conduct reminder. The judge’s discussion of counsel’s duty to avoid Pyrrhic victories connects costs law to professional ethics. In practice, this means that when considering whether to commence in the High Court, counsel should document and communicate to clients the risks of costs consequences, including the possibility that costs will be capped at State Courts scales if the damages outcome does not justify High Court proceedings.
