Summary
This decision of the Singapore Court of Appeal concerns a challenge to ICC arbitral awards arising out of two related sale and purchase agreements (SPAs) for interests in Thai windfarm project companies. The appellants (buyers) sought to set aside parts of the tribunal’s Phase II Partial Awards and, consequentially, the final costs award. Their grounds were that the tribunal exceeded its jurisdiction, failed to afford them a reasonable opportunity to present their case (natural justice), and contravened Singapore public policy—particularly in relation to the award of compound interest.
The Court of Appeal upheld the ICC judge’s dismissal of the setting-aside applications. It affirmed that the tribunal had jurisdiction over the “Remaining Amounts” even if the buyers had also pursued a separate arbitration to contest acceleration of payment dates. It further accepted that the buyers had not demonstrated a failure of natural justice, despite their non-disclosure of the nature and grounds of the separate “ALRO arbitration” to the tribunal. On compound interest, the Court agreed that the illegality under Thai law did not amount to the kind of “palpable and indisputable” illegality that would necessarily engage Singapore public policy to set aside the award.
What Were the Facts of This Case?
The underlying commercial dispute arose from two SPAs dated 19 June 2015, governed by Thai law, under which the parties agreed to sell and purchase substantial minority interests in a Thai corporate group owning windfarm projects. SPA I involved the sale by CBZ (seller) to CBX (buyer) of 49% interests in company AAA, which in turn owned 59.46% of company BBB. BBB, through various project companies, owned eight windfarm projects (three existing and five in progress and incomplete at the time the SPAs were entered into). SPA II involved a different set of sellers (CCA and CCB) and a buyer (CBY), for the sale of 48.94% interests in company AAA.
Both SPAs contained an arbitration clause providing for ICC arbitration seated in Singapore in the event of disputes. Disputes arose in June 2016, leading to two arbitrations heard together by the same tribunal: one arbitration under SPA I (with CBZ as claimant and CBX as respondent) and another under SPA II (with CCA and CCB as claimants and CBY as respondents). The tribunal issued multiple awards: Phase I Partial Awards dated 22 September 2017; Phase II Partial Awards dated 5 June 2019; and a final award on costs dated 9 August 2019. The Phase II awards were later clarified by further awards dated 5 August 2019.
The buyers’ setting-aside applications before the Singapore International Commercial Court targeted specific parts of the Phase II Partial Awards. Those parts concerned (i) the tribunal’s orders that the buyers pay certain sums described as the “Remaining Amounts”, and (ii) the tribunal’s award of compound interest on those sums at a rate of 15% compounded annually from the date of the awards until payment. The buyers argued that the tribunal’s approach was flawed because the Remaining Amounts had originally been claimed on the basis that their due dates were accelerated due to the buyers’ alleged defaults or conduct.
Crucially, while the tribunal ordered payment in accordance with Clause 3.1(ii) of the SPAs (which required payment in tranches tied to milestone dates, including Commercial Operation Dates (COD) and subsequent anniversaries), the tribunal also described the payments as “now become due and payable, from the date of the Partial Award with interest”. This created a potential tension: the last tranches were not, on the face of the contractual schedule, due until one and two years post-COD. In addition, the buyers challenged the tribunal’s award of compound interest. The tribunal later acknowledged a “regrettable oversight” because the parties had agreed that compounding was unlawful and unenforceable under Thai law and had informed the tribunal accordingly during the proceedings.
What Were the Key Legal Issues?
The Court of Appeal had to consider whether the tribunal’s decisions fell within the scope of the parties’ submission to arbitration, and whether the tribunal exceeded its jurisdiction. This required the Court to examine the contractual and procedural context: the tribunal’s orders for payment of the Remaining Amounts, and whether those orders were properly within the claims submitted for determination, particularly given the buyers’ argument that the tribunal effectively decided an issue beyond what was pleaded or within what was contemplated.
Second, the Court had to address whether the buyers were denied a reasonable opportunity to present their case, engaging the natural justice limb of the setting-aside framework. The buyers had commenced another ICC arbitration (referred to as the “ALRO arbitration”) to establish that the Remaining Amounts could not and would not fall due on the relevant payment dates. However, the judge found that the buyers had neglected to make clear to the present tribunal the nature and grounds of that relief, and thus had not shown undue prejudice.
Third, the Court had to determine whether the tribunal’s award of compound interest contravened Singapore public policy. This involved assessing the threshold for public policy review under the International Arbitration Act (s 24) and the UNCITRAL Model Law (Article 34(2)(b)), and whether the illegality under Thai law was sufficiently serious to meet that threshold.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the case within the statutory and international framework for recourse against arbitral awards. Under Article 34 of the UNCITRAL Model Law (as given effect through the International Arbitration Act), an arbitral award may be set aside only on specified grounds. The relevant grounds in this case were: (i) that the award deals with a dispute not contemplated by, or falls outside, the terms of the submission to arbitration (Article 34(2)(a)(iii)); and (ii) that the award is in conflict with the public policy of Singapore (Article 34(2)(b)). The Court emphasised that these grounds are not a general appeal on the merits; they are targeted supervisory controls.
On jurisdiction, the Court endorsed the judge’s approach that Article 34(2)(a)(iii) involves a two-stage process: first, identifying the scope of the submission to arbitration; and second, determining whether the award involved matters outside that scope. The Court referred to established authority that jurisdiction is a “hard-edged” issue for the court to decide de novo. It also recognised that the language “may be set aside” leaves room for circumstances where an excess of jurisdiction might not lead to setting aside, though the Court’s focus in this case was whether the tribunal’s orders were in substance within the pleaded and submitted dispute.
Applying that framework, the Court held that the tribunal had jurisdiction over the Remaining Amounts as such. Even if the buyers disputed acceleration of due dates, the tribunal’s orders were anchored in the SPAs’ payment mechanism—Clause 3.1(ii) and the tranche structure in Schedule 5. The tribunal’s decision did not require it to decide an entirely new dispute; rather, it determined the buyers’ payment obligations under the contractual schedule. The Court accepted that the tribunal could order payment of tranches that were already due at the time of the awards, and that the tribunal’s description of the payments as “now become due and payable” did not, in the circumstances, transform the dispute into one outside the submission to arbitration.
On natural justice, the Court agreed with the judge that the buyers had not demonstrated a failure to afford them a reasonable opportunity to present their case. The Court noted that the buyers had initiated the ALRO arbitration to contest the due dates of the Remaining Amounts. However, the buyers did not clearly communicate to the tribunal the nature and grounds of the relief sought in that separate arbitration. The Court treated this as a procedural omission by the buyers rather than a denial of opportunity by the tribunal. In other words, the buyers could not rely on their own lack of clarity and disclosure to establish that the tribunal had deprived them of a fair hearing.
Finally, on public policy, the Court addressed the compound interest issue. The tribunal had awarded compound interest under Clause 12.9 of the SPAs, but later acknowledged that the parties had agreed compounding was unlawful and unenforceable under Thai law and had informed the tribunal. The buyers argued that this illegality should trigger Singapore public policy and lead to setting aside. The Court, however, maintained a high threshold for public policy intervention. It agreed with the judge that the illegality must be of a sufficiently serious character—described in the judgment as “palpable and indisputable”—to warrant setting aside on public policy grounds. The Court concluded that the situation did not meet that threshold, particularly given the tribunal’s procedural power to award interest and the fact that the error was essentially an incorrect application of the law rather than an obvious and indisputable breach that would shock Singapore’s public conscience.
In reaching this conclusion, the Court also reflected on the limited role of supervisory courts in arbitration. The public policy ground is not intended to convert the setting-aside process into a merits review. Where the tribunal had jurisdiction and the parties had an opportunity to present their case, the court will generally not interfere merely because the tribunal made an error of law or overlooked an agreed position, unless the error rises to the level required by the public policy doctrine.
What Was the Outcome?
The Court of Appeal dismissed the buyers’ appeal against the ICC judge’s decision. It therefore upheld the refusal to set aside the relevant parts of the Phase II Partial Awards and the consequential Final Award (Costs). The practical effect was that the tribunal’s orders for payment of the Remaining Amounts and the award of compound interest remained enforceable, subject to any separate enforcement proceedings and any other procedural steps not addressed in this appeal.
The Court also upheld the judge’s costs order in the related proceedings before the ICC (as reflected in the separate judgment delivered by Prakash JCA for CA 197). Overall, the decision confirmed that the supervisory court would not readily interfere with arbitral awards on jurisdiction, natural justice, or public policy grounds where the tribunal’s determinations were within the contractual submission and where the alleged procedural unfairness was not established.
Why Does This Case Matter?
This case is significant for practitioners because it reinforces the narrow scope of judicial review under Article 34 of the Model Law as implemented in Singapore. The Court’s analysis illustrates that “excess of jurisdiction” is assessed by reference to the scope of the arbitration submission and the substance of what the tribunal decided, not by formalistic characterisation of claims. Where the tribunal’s orders can be traced to the contractual payment mechanism, the court is likely to treat them as within the submission even if the tribunal’s reasoning or wording creates interpretive difficulties.
Second, the decision highlights practical expectations regarding disclosure and procedural coordination in multi-track disputes. The buyers’ initiation of a separate arbitration (the ALRO arbitration) did not automatically require the tribunal to stay or adjust its approach. Instead, the buyers needed to clearly communicate the nature and grounds of the relief they sought. The Court’s reasoning suggests that parties cannot rely on their own failure to present relevant procedural context as a basis for natural justice complaints.
Third, the public policy discussion on compound interest provides guidance on the threshold for setting aside arbitral awards for illegality. Even where the tribunal awarded interest in a manner later acknowledged to be unlawful under the governing law, the Court treated the issue as insufficient to meet the “palpable and indisputable” standard required for public policy intervention. This is a useful benchmark for counsel assessing whether an arbitral illegality argument is likely to succeed in Singapore.
