Summary
WRP Asia Pacific Sdn Bhd sought to set aside an arbitral award issued in its dispute with Grant Thornton Singapore Pte Ltd over unpaid invoices for forensic investigation services. WRP’s central complaint was that the arbitral tribunal’s interpretation of a key contractual clause—clause 9.5 of the parties’ Engagement Letter—was inconsistent with the way the parties had pleaded and argued the case. WRP contended that this led to a breach of the rules of natural justice (fair hearing) and also amounted to an excess of jurisdiction.
The High Court (Aidan Xu @ Aedit Abdullah J) dismissed the setting-aside application. The court held that WRP failed to establish any breach of natural justice under the International Arbitration Act and the UNCITRAL Model Law. In particular, the tribunal’s reasoning was found to address the arguments raised by WRP in its submissions, and there was no basis to conclude that WRP was deprived of a fair opportunity to present its case. The court also rejected the “excess of jurisdiction” argument, finding that the tribunal did not decide an issue outside the parties’ submission to arbitration.
What Were the Facts of This Case?
WRP Asia Pacific Sdn Bhd is a Malaysian-incorporated company engaged in the manufacturing and export of disposable medical, industrial and specialty glove products. Grant Thornton Singapore Pte Ltd is a Singapore-incorporated professional services firm, including forensic investigations. The relationship between the parties arose from Grant Thornton’s engagement to support WRP in litigation pursued in the Malaysian High Court.
On 22 November 2021, the parties entered into an Engagement Letter titled “Terms of Engagement – Provision of professional services”. The engagement required Grant Thornton to conduct forensic investigations into alleged wrongdoings committed by WRP’s former CEO, director and shareholder, and his spouse. The scope of work was structured into 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.
Between 29 April 2022 and 14 August 2023, Grant Thornton issued seven interim invoices for work it said had been completed under the relevant phases. WRP made partial payment of the first interim invoice but retained a portion to meet withholding tax obligations in Malaysia. WRP disputed the amounts claimed under the second to seventh invoices, leading to the commencement of arbitration.
On 4 March 2024, Grant Thornton commenced arbitration seeking recovery of outstanding sums. One of the issues in the arbitration concerned the fifth invoice. Grant Thornton’s position was that it had completed work falling within Phase 1B and Phase 3 pursuant to WRP’s instructions, and therefore was entitled to charge hourly rates under the Engagement Letter. WRP’s position was that no sums were payable for that invoice because Grant Thornton had not been explicitly instructed to commence work related to Phase 1B and Phase 3, and that the work performed was instead within Phase 1A and subject to the fee cap.
WRP further relied on clause 9.5 of the Engagement Letter. Clause 9.5, as quoted in the judgment, provided that the fee cap was based on an assumption of 2,000 man-hours for Phase 1A, and that Grant Thornton would discuss ongoing work regularly, notify WRP, and seek approval before proceeding with any additional scope where necessary. WRP argued that Grant Thornton failed to notify and obtain approval before commencing work falling outside Phase 1A, and that this failure should prevent Grant Thornton from charging hourly rates for work under Phase 1B and Phase 3.
What Were the Key Legal Issues?
The High Court identified two main legal questions that governed the application to set aside the award. 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 under s 24 of the International Arbitration Act and/or Art 34(2)(a)(ii) of the UNCITRAL Model Law.
Second, whether the tribunal’s approach amounted to a breach of Art 34(2)(a)(iii) of the Model Law, which addresses situations where the arbitral tribunal exceeds its jurisdiction. WRP’s theory was that the tribunal decided an issue outside the scope of submission to arbitration, because the parties had allegedly agreed (or at least proceeded on the basis) that clause 9.5 applied to work across multiple phases, not just Phase 1A.
In addition, the court had to address the practical consequences of any finding of breach. WRP argued that if there were a breach of natural justice, the award should be set aside in its entirety, and that partial setting aside or remission was not available in the circumstances. Grant Thornton, by contrast, argued that even if there were a breach, it was not causally linked to the making of the award and that any remedy should be limited to the relevant issue (the fifth invoice) or involve remission/redetermination.
How Did the Court Analyse the Issues?
The court’s analysis began with the core complaint: whether the tribunal’s finding on clause 9.5 was inconsistent with the parties’ pleaded and argued positions such that WRP was denied a fair hearing. WRP framed the alleged natural justice breach as a “defective chain of reasoning”. The argument was that the tribunal adopted a reasoning pathway that was not fairly open on the pleadings and submissions, and that this deprived WRP of the opportunity to address the tribunal’s ultimate interpretation of clause 9.5.
In assessing this, the court focused on what the tribunal actually did. The judgment emphasised that WRP’s complaint was essentially about the tribunal’s interpretation of clause 9.5 and the resulting conclusion on the fifth invoice. However, the court found that the tribunal had reached its conclusion by addressing the arguments made by WRP in presenting its case. In other words, the tribunal was not deciding a wholly new issue or relying on a basis that WRP had no opportunity to meet. The tribunal’s reasoning was therefore not characterised as a fair hearing breach.
The court also considered WRP’s reliance on the parties’ pleadings and submissions. WRP argued that both parties had “pleaded and acted on the basis” that clause 9.5 applied not only to Phase 1A but also to Phase 1B and the other phases. WRP pointed to Grant Thornton’s statement of claim, which included an assertion 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, which it said highlighted there was no approval from WRP before Grant Thornton proceeded with work beyond Phase 1A.
Despite this, the court did not accept that the tribunal’s interpretation necessarily meant WRP was denied a fair hearing. The court’s approach reflects a key arbitration principle: natural justice is concerned with procedural fairness—whether the party had a reasonable opportunity to present its case—rather than whether the tribunal’s reasoning is persuasive or whether the tribunal’s interpretation aligns with one party’s preferred reading. The court found that WRP had raised the interpretation issue and that the tribunal’s decision addressed that dispute.
On the “excess of jurisdiction” ground, the court examined whether the tribunal decided an issue outside the scope of submission. WRP’s position was that because the parties had allegedly agreed on the scope of clause 9.5, the tribunal’s conclusion that clause 9.5 applied only to Phase 1A went beyond what was submitted. The court rejected this. It held that WRP was not able to show that the tribunal had stepped outside its jurisdiction; rather, the tribunal was resolving the interpretation dispute that was squarely before it.
The court also addressed a related conceptual point: WRP argued that if the court found a natural justice breach, it should set aside the award in its entirety and that partial setting aside was not permissible. The court’s reasoning indicates that remedy is tied to the nature and effect of any breach. Where the alleged procedural defect does not undermine the award-making process in a way that warrants full setting aside, the court will be cautious about granting expansive relief. In this case, because the court found no breach of natural justice and no excess of jurisdiction, the question of partial setting aside or remission did not arise in WRP’s favour.
Finally, the judgment addressed the applicable legal framework for setting aside under the International Arbitration Act and the Model Law. The court treated the grounds invoked by WRP as requiring a high threshold. The court’s conclusion—no breach of natural justice and no excess of jurisdiction—meant that the award stood.
What Was the Outcome?
The High Court dismissed WRP’s application to set aside the arbitral award. The practical effect is that Grant Thornton retained the benefit of the award for the unpaid invoices determined by the tribunal, including the amount relating to the fifth invoice.
By rejecting both the natural justice and excess of jurisdiction grounds, the court confirmed that the tribunal’s interpretation of clause 9.5 and its application to the fifth invoice were within the tribunal’s remit and were reached through a process consistent with procedural fairness.
Why Does This Case Matter?
This decision is significant for arbitration practitioners in Singapore because it illustrates the narrow scope of court intervention when a party seeks to set aside an award. The court reaffirmed that allegations framed as “defective chain of reasoning” will not automatically translate into a breach of natural justice. The focus remains on whether the arbitral process deprived the party of a fair opportunity to present its case, not on whether the tribunal’s reasoning or contractual interpretation ultimately favoured the other side.
For counsel, the case also underscores the importance of how interpretive disputes are pleaded and argued in arbitration. WRP attempted to characterise the tribunal’s clause interpretation as unforeseeable and outside the parties’ agreed positions. The court’s response indicates that where the interpretation question is part of the live dispute—raised in pleadings, submissions, or closing arguments—the tribunal’s resolution of that question is unlikely to be characterised as an excess of jurisdiction.
From a drafting and case-management perspective, the decision highlights the practical consequences of contractual phase structures and approval mechanisms. Clause 9.5 was central to the parties’ dispute about whether work beyond Phase 1A required notification and approval before hourly rates could be charged. While the tribunal’s interpretation prevailed, the court’s analysis shows that even where a party believes the tribunal’s reading differs from its own, that disagreement alone does not justify setting aside unless procedural fairness or jurisdictional boundaries are genuinely breached.
