Summary
In WRP Asia Pacific Sdn Bhd v Grant Thornton Singapore Pte Ltd ([2025] SGHC 198), the High Court dismissed WRP’s application to set aside an arbitral award. WRP’s central complaint was that the arbitral tribunal (“Tribunal”) misinterpreted clause 9.5 of the parties’ engagement letter and, in doing so, breached the rules of natural justice and acted in excess of jurisdiction. WRP argued that the parties had agreed that clause 9.5 applied not only to Phase 1A but also to Phases 1B, 2 and 3, and that the Tribunal’s contrary conclusion deprived WRP of a fair hearing.
The court held that WRP failed to establish any breach of natural justice under the statutory framework for setting aside. The Tribunal had addressed the arguments WRP advanced on the interpretation of clause 9.5, and its reasoning was not so defective as to amount to a fair hearing breach. The court also rejected the “excess of jurisdiction” argument under Art 34(2)(a)(iii) of the Model Law, finding that the Tribunal was deciding an issue within the parties’ submissions and that the Tribunal’s interpretation of clause 9.5 was within its remit.
What Were the Facts of This Case?
WRP Asia Pacific Sdn Bhd is a Malaysian-incorporated company engaged primarily in manufacturing and exporting disposable medical, industrial and other specialty glove products. Grant Thornton Singapore Pte Ltd is a Singapore-incorporated professional services firm providing, among other things, forensic investigations. The relationship between the parties arose from litigation-related work that Grant Thornton was engaged to perform in connection with alleged wrongdoing by WRP’s former CEO, director and shareholder, and his spouse.
On 22 November 2021, the parties entered into an agreement titled “Terms of Engagement – Provision of professional services” (the “Engagement Letter”). The Engagement Letter set out Grant Thornton’s scope of work in phases: Phase 1A, Phase 1B, Phase 2 and Phase 3. For Phase 1A, the parties agreed on a fee cap of S$480,000. For Phases 1B, 2 and 3, fees were to be calculated by reference to specified hourly rates. This structure mattered because WRP’s position was that certain work should have been treated as falling within the capped Phase 1A, whereas Grant Thornton contended that it was properly within the uncapped hourly-rate phases.
Between 29 April 2022 and 14 August 2023, Grant Thornton issued seven interim invoices to WRP for work allegedly completed under Phases 1A, 1B and 3. WRP made partial payment of the first interim invoice but retained a portion to fulfil withholding tax obligations in Malaysia. WRP disputed the amounts payable under the second to seventh invoices. The dispute crystallised into an arbitration commenced by Grant Thornton on 4 March 2024 to recover outstanding sums.
One of the key issues in the arbitration concerned the fifth invoice. Grant Thornton asserted that it had completed work under Phase 1B and Phase 3 pursuant to WRP’s instructions and was therefore entitled to be paid at the agreed hourly rates. WRP argued that no sums were payable for the fifth invoice because Grant Thornton had not been explicitly instructed to commence work in relation to Phase 1B and Phase 3. WRP also relied on clause 9.5 of the Engagement Letter, contending that Grant Thornton was required to notify WRP and submit fee estimates for approval before commencing any work falling outside Phase 1A, and that it failed to do so.
What Were the Key Legal Issues?
The application for setting aside turned on two main legal questions. First, whether the Tribunal’s interpretation of clause 9.5—specifically, its conclusion that clause 9.5 applied only to work done in relation to Phase 1A—constituted a breach of the rules of natural justice, as captured by IAA s 24 and Model Law Art 34(2)(a)(ii). WRP framed this as a “fair hearing” problem, arguing that the Tribunal adopted a defective chain of reasoning and reached a conclusion that was unforeseeable given how the parties had pleaded and argued the clause.
Second, WRP argued that the Tribunal exceeded its jurisdiction under Model Law Art 34(2)(a)(iii). The essence of this argument was that the Tribunal decided an issue outside the scope of submission to arbitration. In WRP’s view, the Tribunal’s approach effectively shifted the interpretive question in a manner not contemplated by the parties’ submissions, thereby going beyond what it was empowered to determine.
How Did the Court Analyse the Issues?
The High Court began by identifying the core dispute: whether the parties had agreed on the scope and operation of clause 9.5. The court treated this as the factual-interpretive pivot for both legal grounds advanced by WRP. In setting aside applications, the court’s role is not to re-try the arbitration or correct errors of law or fact unless the statutory threshold for intervention is met. Accordingly, the court examined whether WRP’s complaints fit within the narrow grounds for setting aside under the IAA and the Model Law.
On natural justice, WRP’s argument was that the parties had “pleaded and acted” on the basis that clause 9.5 applied to more than Phase 1A, including Phase 1B and other phases. WRP pointed to its own and Grant Thornton’s pleadings and submissions in the arbitration, including Grant Thornton’s statement of claim that, pursuant to clause 9 (in particular clauses 9.3 to 9.5, 9.7 and 9.9), WRP agreed to pay professional fees incurred for Phases 1B and 3. WRP also relied on its defence position that it had not approved work beyond Phase 1A and that Grant Thornton had not complied with clause 9.5’s notification and approval requirements.
The court’s analysis focused on whether the Tribunal’s reasoning process deprived WRP of a fair opportunity to present its case. The court accepted that WRP had raised the interpretation of clause 9.5 in its closing submissions, and it found that the Tribunal had reached its conclusion by addressing the arguments WRP made. The court therefore concluded that there was no breach of the fair hearing rule. In other words, the Tribunal’s interpretation was not reached in a way that prevented WRP from responding to the interpretive issue; rather, it was a determination of the issue that WRP itself had put before the Tribunal.
WRP also characterised the Tribunal’s reasoning as a “defective chain of reasoning” that resulted in prejudice. The court did not accept that framing as sufficient. The court’s approach was consistent with the principle that natural justice complaints must show a real procedural unfairness, not merely that the tribunal’s reasoning or conclusion is unpersuasive. Here, the court found that the Tribunal’s conclusion addressed the arguments presented and did not involve a procedural ambush or a failure to consider the substance of WRP’s case.
On excess of jurisdiction, the court examined whether the Tribunal decided an issue outside the parties’ scope of submission. WRP argued that the Tribunal’s interpretation of clause 9.5 effectively decided a different question than the one submitted. The court rejected this. It found that the Tribunal was addressing an argument that WRP itself had made concerning the interpretation of clause 9.5 and the consequences for the fifth invoice. As a result, the Tribunal’s decision fell within its jurisdiction to interpret the contract and determine the parties’ rights under the engagement letter.
The court also addressed the applicable legal framework for setting aside. WRP invoked IAA s 3(1) read with Model Law provisions and relied on IAA s 24 and Art 34(2)(a)(ii) for natural justice, as well as Art 34(2)(a)(iii) for excess of jurisdiction. The court’s reasoning reflected the statutory design: setting aside is exceptional and requires strict satisfaction of the enumerated grounds. Because WRP did not establish the procedural or jurisdictional defects alleged, the court did not grant relief.
Finally, the court considered remedy. WRP contended that if there was a breach of natural justice, the award should be set aside in its entirety and that partial setting aside was not available. It also argued that remission to the Tribunal for redetermination was not appropriate because Grant Thornton had not applied for remission. However, since the court found no breach of natural justice and no excess of jurisdiction, it did not need to decide the finer points of remedy in depth.
What Was the Outcome?
The High Court dismissed WRP’s application to set aside the arbitral award. The court held that WRP failed to make out any sufficient basis under the IAA and the Model Law for intervention.
Practically, the dismissal meant that the arbitral award remained enforceable, and the parties’ dispute over the fifth invoice (and the award as a whole) was not reopened by the court. The decision reinforces the limited supervisory role of the High Court over arbitral awards in Singapore.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates the high threshold for setting aside arbitral awards on natural justice and excess of jurisdiction grounds. A common misconception in arbitration-related litigation is that an unfavourable interpretation of a contract clause automatically implies procedural unfairness. WRP Asia Pacific demonstrates that the court will look closely at whether the tribunal actually deprived a party of a meaningful opportunity to present its case, rather than focusing solely on whether the tribunal’s reasoning aligns with a party’s preferred interpretation.
The decision also underscores that “excess of jurisdiction” is not a vehicle for re-litigating contractual interpretation. Where the tribunal’s determination concerns an issue raised by the parties’ pleadings and submissions—particularly where the party challenging the award had itself raised the interpretive question—the court is unlikely to find that the tribunal acted beyond its mandate.
For counsel, the case highlights the importance of framing and preserving interpretive arguments in arbitration. If a party raises an interpretive issue (such as the scope of clause 9.5) and the tribunal addresses it, a later attempt to characterise the tribunal’s conclusion as unforeseeable or procedurally unfair is less likely to succeed. The decision therefore serves as a caution to parties considering setting aside applications: the grounds must be anchored in demonstrable procedural defects or genuine jurisdictional overreach, not merely disagreement with the tribunal’s reasoning.
