Summary
CBX and CBY (“the Buyers”) sought to set aside parts of two Phase II Partial Awards and, consequentially, the Final Award (Costs) made in related ICC arbitrations seated in Singapore. The underlying disputes arose from two sale and purchase agreements (“SPA I” and “SPA II”) governed by Thai law, under which the Sellers sold minority interests in companies that, in turn, owned windfarm projects in Thailand. The arbitral tribunal ordered payment of “Remaining Amounts” in tranches and awarded compound interest at 15% compounded annually.
The Singapore Court of Appeal (per Jonathan Mance IJ) upheld the High Court’s dismissal of the Buyers’ setting-aside applications. The court affirmed that the tribunal had jurisdiction over the Remaining Amounts independent of any separate “acceleration” theory advanced by the Sellers, that the Buyers had not been denied a reasonable opportunity to present their case, and that the award of compound interest—despite its illegality under Thai law—did not cross the high threshold required to offend Singapore public policy under the Model Law framework.
What Were the Facts of This Case?
The disputes stemmed from two interlinked sale and purchase agreements dated 19 June 2015. SPA I was between CBZ (seller) and CBX (buyer) for the sale of 49% of an interest in company AAA, which owned 59.46% of company BBB. BBB, through various project companies, owned eight windfarm projects in Thailand. SPA II involved CCA and CCB as sellers and CBY as buyer, for the sale of 48.94% of the interest in company AAA. Both SPAs contained arbitration clauses 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. The Sellers in each arbitration sought relief against the Buyers. The arbitral process produced multiple awards: Phase I Partial Awards dated 22 September 2017, Phase II Partial Awards dated 5 June 2019, and a Final Award (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 High Court targeted specific parts of the Phase II Partial Awards and, consequentially, the costs award.
The relevant Phase II orders concerned two main issues. First, the tribunal ordered the Buyers to pay certain sums described as the “Remaining Amounts”. These sums had originally been claimed on the basis that their due dates were accelerated due to the Buyers’ defaults or conduct. However, the tribunal’s actual operative orders required payment according to Clause 3.1(ii) of the SPAs, which in turn required payment in tranches for each of the five incomplete windfarm projects, as set out in Schedule 5. The schedule specified milestone dates tied to each project’s Commercial Operation Date (“COD”), with payments due within 45 days of COD, one year post-COD, and two years post-COD.
At the time the arbitrations were commenced and the post-hearing briefs were exchanged (October/November 2018), none of the tranche payment dates had yet been reached. By the date of the Phase II Partial Awards (5 June 2019), the first tranche payment dates had passed, but the second and third tranches were not yet due. The tribunal nonetheless referred to all Schedule 5 payments as “now become due and payable, from the date of the Partial Award with interest”, and ordered compound interest to run “as from the date of this Partial Award”. Second, the tribunal awarded compound interest on the Remaining Amounts under Clause 12.9 of the SPAs. The tribunal later acknowledged a “regrettable oversight”: the parties had agreed that compounding was unlawful and unenforceable under Thai law, and the tribunal had been informed of this during the proceedings.
What Were the Key Legal Issues?
The Buyers’ applications to set aside were brought under the Singapore statutory regime implementing the Model Law. The central legal issues were whether the tribunal (a) exceeded its jurisdiction, (b) failed to afford the Buyers a reasonable opportunity to present their case (a natural justice / procedural fairness concern), and/or (c) contravened Singapore public policy by awarding compound interest that was unlawful under Thai law. In addition, the Buyers argued that the Final Award (Costs) could not stand if the underlying parts of the Phase II Partial Awards were set aside in whole or part.
On jurisdiction, the dispute was whether the tribunal’s orders for payment of the Remaining Amounts were within the scope of the parties’ submission to arbitration. The Buyers contended that the tribunal effectively decided matters beyond what was submitted, particularly given that the Sellers had advanced an “acceleration” case. The High Court had held that the tribunal’s jurisdiction extended to the Remaining Amounts as they existed independently of any acceleration theory.
On procedural fairness, the Buyers argued that they were not given a reasonable opportunity to address the tribunal’s approach. A related factual element was that the Buyers had commenced another ICC arbitration (the “ALRO arbitration”) to establish that the Remaining Amounts could not and would not fall due on the relevant payment dates. The question was whether the Buyers had sufficiently brought the nature and grounds of that relief to the tribunal in the present arbitrations, and whether any omission caused actual prejudice amounting to a breach of Article 34(2)(b).
On public policy, the key question was whether the tribunal’s award of compound interest—despite its illegality under Thai law—was the kind of illegality that would render the award contrary to Singapore public policy. The court had to consider the threshold for public policy intervention under Article 34(2)(b) and the Model Law’s approach to enforcing arbitral awards while preserving limited grounds for judicial interference.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the case within the Model Law framework. Under Article 34(2)(a)(iii), an award may be set aside if it deals with a dispute not contemplated by, or falls outside, the terms of the submission to arbitration. The court emphasised that jurisdiction and scope of submission are “hard-edged” questions for the court to decide de novo. The court also noted that the language “may be set aside” indicates that even where excess of jurisdiction is established, there may be circumstances in which the court will not set aside the award.
On the jurisdictional issue, the court examined what the tribunal actually ordered. Although the Sellers’ claims had been framed around acceleration of due dates, the tribunal’s operative orders required payment in accordance with Clause 3.1(ii) and Schedule 5. This meant that the tribunal was not necessarily deciding an acceleration dispute; rather, it was determining the payment obligations under the contractual tranche mechanism. The Court of Appeal agreed with the High Court that the tribunal had jurisdiction over claims to the Remaining Amounts that existed independently of any acceleration theory. In other words, the tribunal’s decision did not fall outside the scope of the submission to arbitration merely because the tribunal’s reasoning or emphasis differed from the parties’ pleaded acceleration narrative.
On procedural fairness, the court focused on whether the Buyers had been denied a reasonable opportunity to present their case. The Buyers had started the ALRO arbitration to challenge the due dates of the Remaining Amounts. However, the High Court had found that the Buyers had neglected to make clear to the tribunal the nature and grounds of the relief sought in the ALRO arbitration. The Court of Appeal endorsed this approach, reasoning that the tribunal had not been deprived of relevant information in a way that would amount to a failure of natural justice. The court treated the alleged procedural unfairness as insufficient to meet the Model Law threshold, particularly where the Buyers’ own conduct contributed to the tribunal’s understanding of the issues.
On public policy, the court addressed the award of compound interest. The tribunal had acknowledged that compounding was unlawful and unenforceable under Thai law, and that the parties had informed the tribunal of this. The Buyers argued that the illegality should trigger set-aside under Singapore public policy. The court, however, accepted the High Court’s view that not every error involving foreign-law illegality automatically engages public policy. The court considered the concept of “palpable and indisputable” illegality and the limited circumstances in which an award will be set aside for public policy reasons. The court concluded that the illegality here did not reach the level required to render the award contrary to Singapore public policy.
In reaching this conclusion, the court also implicitly balanced two competing arbitration policy considerations: first, the finality and enforceability of arbitral awards; and second, the need for a safety valve where enforcement would be fundamentally unacceptable. The court characterised the tribunal’s error as an incorrect exercise of an undoubted power rather than a situation where the tribunal had no authority to award interest at all. The court treated the risk of such errors as a “routine hazard of arbitration”, reinforcing that judicial review under Article 34 is not an appeal on the merits.
Finally, the court addressed the consequential challenge to the costs award. Because the court did not set aside the relevant parts of the Phase II Partial Awards, the costs award—predicated on those awards—also remained intact.
What Was the Outcome?
The Court of Appeal dismissed the Buyers’ appeal against the High Court’s decision. It upheld the tribunal’s jurisdiction to order payment of the Remaining Amounts and found no breach of procedural fairness that would justify setting aside under Article 34(2)(b). It further held that the compound interest award, although unlawful under Thai law, did not contravene Singapore public policy to the extent required for set-aside.
As a result, the Final Award (Costs) dated 9 August 2019 was not disturbed on the basis of the Buyers’ consequential argument. The practical effect was that the arbitral awards remained enforceable in Singapore, subject only to any separate costs-related determinations addressed in the separate appeal judgment.
Why Does This Case Matter?
This decision is significant for practitioners because it clarifies how Singapore courts approach the Model Law grounds for setting aside in the context of international arbitration seated in Singapore. In particular, it reinforces that “excess of jurisdiction” under Article 34(2)(a)(iii) is assessed by reference to the scope of the submission to arbitration and what the tribunal actually decided, not merely the way parties framed their claims. Even where a tribunal’s reasoning appears to diverge from a party’s acceleration theory, the award will generally stand if the tribunal’s orders fall within the contractual and dispute framework submitted to arbitration.
The case also highlights the importance of procedural diligence. Where a party runs parallel proceedings (such as the ALRO arbitration) that may bear on the tribunal’s understanding of due dates or contractual obligations, that party must ensure the tribunal is clearly apprised of the nature and grounds of the relief sought. The court’s analysis suggests that failure to do so may undermine later complaints of denial of a reasonable opportunity to present one’s case.
On public policy, the decision underscores a high threshold. Illegality under the governing law of the contract (here, Thai law) does not automatically translate into a public policy breach in Singapore. The court’s approach aligns with the broader arbitration policy of limited judicial intervention: set-aside for public policy is reserved for cases where enforcement would be fundamentally contrary to Singapore’s most basic notions of morality and justice, and where the illegality is sufficiently clear and unacceptable.
