Summary
In DEM v DEL ([2025] SGCA 1), the Court of Appeal considered the scope of recourse against an arbitral award under the Arbitration Act 2001, focusing on three interrelated grounds: (1) whether the appellant received proper notice of the arbitration and the arbitrator’s appointment; (2) whether an “infra petita” complaint (that the arbitrator failed to consider an essential issue not put in issue) can be framed as a natural justice challenge; and (3) whether a party who chose not to participate in the arbitration can nonetheless rely on an infra petita ground to set aside the award.
The Court of Appeal dismissed the appeal. While it agreed that the High Court’s analysis on the infra petita point was incorrect in one respect—namely, that the arbitrator did not actually address the “lack of consideration” issue—the Court held that the infra petita challenge was not available to the appellant because he had elected not to participate and had not raised the issue during the arbitration. The court also upheld the High Court’s conclusion that the appellant had notice of the arbitration, and that there was no breach of natural justice warranting the setting aside of the award.
What Were the Facts of This Case?
The dispute arose out of the sale of a franchised enrichment centre (“Franchise”) pursuant to a Business Purchase Agreement dated 4 January 2019 (“BPA”). The respondent (a Singapore company incorporated for the acquisition) sought to acquire the Franchise from three sellers: the appellant, Z Co, and Ms Y (the sole legal owner of Z Co). The transaction was supported by three agreements signed on the same date: the BPA (for the purchase of the Franchise for $200,000), a shareholders’ agreement under which the appellant would hold 30% of the respondent’s shares, and an employment agreement under which the appellant would be employed as Head of Operations.
Each agreement contained “Notice” clauses. The appellant provided two contact details: (a) a physical address at a flat in Tampines (“Tampines Address”); and (b) an email address (the “K Email Address”). These details were contractually permitted for service and communications. After the Franchise commenced operations, the respondent discovered that the Franchise generated significantly less revenue than expected. It alleged that the appellant, Ms Y and Z Co had diverted clients and staff, misappropriated teaching curriculum, and misrepresented the Franchise’s revenue potential.
To pursue its claims, the respondent commenced arbitration on 29 October 2019 by filing a notice of arbitration (“2019 NOA”) in the Singapore International Arbitration Centre (“SIAC”). The respondent initially sought consolidation across the three agreements, but SIAC rejected the consolidation application on 2 March 2020. On 29 May 2020, the respondent informed SIAC that it would proceed only under the BPA. Around this period, the appellant ceased to be represented by Farallon Law and stopped participating in the arbitration.
On 14 August 2020, the respondent filed a further notice of arbitration (“2020 NOA”) against the appellant, Ms Y and Z Co under the BPA. SIAC appointed a sole arbitrator on 22 October 2020. A settlement was later reached between the respondent and Ms Y and Z Co, so the arbitration proceeded only against the appellant. The hearing took place on 8 September 2021. Immediately after the hearing, the arbitrator received an unexpected email from an unknown sender using a different email address (“J Email Address”), claiming to be the appellant and requesting that arbitration correspondence be sent to that new email address. The arbitrator and the respondent’s lawyers attempted to verify the sender’s identity and to engage with him, but received no response. The arbitrator then asked Ms Y’s lawyers to check whether Ms Y had informed the appellant about the arbitration; they confirmed she had not. The arbitration proceeded without further communication from the J Email Address sender until much later, during enforcement proceedings.
The arbitration was declared closed on 19 November 2022, and the arbitrator published the award on 27 April 2023 (“Award”). The respondent then sought enforcement in the Singapore courts and obtained a judgment entered in terms of the Award on 12 June 2023. On 20 July 2023, the respondent applied for substituted service of the enforcement judgment at the appellant’s last known email addresses and via eLitigation to his Singpass inbox. The appellant reappeared on 21 July 2023, sending emails alleging that he had only recently learned of the Award and that he had not been given proper notice of the arbitration, while also requesting service at a different residential address and seeking documents from the arbitration.
What Were the Key Legal Issues?
The Court of Appeal identified and addressed several legal questions, but the appeal turned on three main issues. First, the court had to determine whether the appellant had received proper notice of the arbitration and the arbitrator’s appointment, as required for procedural fairness and as a statutory basis for setting aside an award under the Arbitration Act framework.
Second, the court considered the “Infra Petita Ground”. The appellant argued that the arbitrator failed to consider an essential issue—specifically, that there was no consideration supporting the BPA as against him. The appellant’s position was that this issue was not raised in the arbitration because he was not served with the 2020 NOA. The High Court had treated the infra petita complaint as failing because the arbitrator had implicitly dealt with the issue. On appeal, the Court of Appeal had to decide whether the infra petita challenge could be characterised as a natural justice challenge, and whether such a challenge was available to a party who did not participate in the arbitration.
Third, the court examined whether there was any breach of natural justice. The appellant advanced multiple instances of alleged unfairness, including alleged failures relating to notice of the arbitrator’s appointment and arbitration documents, and alleged procedural unfairness in the arbitrator’s decision to proceed despite the appellant’s attempt to participate late. The Court of Appeal ultimately assessed whether these complaints met the threshold for setting aside an award.
How Did the Court Analyse the Issues?
Notice: actual or deemed notice and contractual service arrangements
The Court of Appeal upheld the High Court’s conclusion that the appellant had notice of the arbitration. The analysis proceeded on the basis that the BPA’s notice clauses permitted service at the Tampines Address and the K Email Address. The appellant’s argument on appeal focused on the contention that clause 11.1 of the BPA did not provide for service by email as an agreed method, and therefore he did not have proper notice of documents sent to the K Email Address. However, the court noted that the appellant did not dispute that documents were served at the Tampines Address.
On the evidence, the court found no basis to conclude that service at the Tampines Address failed. The court also emphasised the absence of evidence of non-receipt. In arbitration-related setting aside proceedings, the court’s approach is pragmatic: where contractual notice mechanisms are agreed and followed, and where there is no credible evidence that the party did not receive the relevant communications, the “lack of proper notice” ground is difficult to sustain. The court further considered whether any alleged defect in notice could have caused prejudice, and agreed with the High Court that the appellant’s deliberate decision not to participate meant that proper service would not have made a difference to the outcome.
Infra petita: mischaracterisation and the effect of non-participation
The Court of Appeal then addressed the infra petita complaint. It accepted that the High Court’s reasoning was wrong in one respect: contrary to the High Court’s view, the arbitrator did not actually consider the “lack of consideration” issue. This mattered because it meant the infra petita complaint was not defeated by an “implicit consideration” analysis.
However, the Court of Appeal held that the infra petita ground was nonetheless not available to the appellant. The court’s reasoning was anchored in the procedural logic of arbitration: if a party does not participate and does not raise an issue that it could have raised, it should not be able to later invoke an infra petita complaint as a basis to set aside the award. The court treated the appellant’s non-participation as decisive. Even if the arbitrator failed to consider a point, the appellant’s failure to put that point in issue during the arbitration meant that the complaint could not be elevated into a setting-aside ground.
In doing so, the Court of Appeal also addressed the appellant’s attempt to rationalise infra petita challenges as natural justice challenges. While natural justice principles are central to arbitration, the court cautioned against collapsing distinct concepts. An infra petita complaint concerns the scope of the arbitrator’s reasoning and whether the arbitrator addressed issues that were properly before the tribunal. A natural justice challenge concerns whether the party was denied a fair opportunity to present its case. The Court of Appeal’s approach indicates that the characterisation of a complaint is not merely semantic; it affects whether the statutory threshold for setting aside is met, particularly where the party’s own conduct contributed to the procedural outcome.
Natural justice: prejudice, parasitic grounds, and the arbitrator’s conduct
The Court of Appeal also considered the appellant’s broader natural justice arguments. The High Court had treated the natural justice ground as parasitic on the first two grounds, meaning that if notice was proper and the infra petita ground was not available, then the natural justice complaints would also fail. The Court of Appeal’s analysis aligned with this structure, though it also independently assessed the fairness of the arbitration process.
On the appellant’s allegations, the court focused on whether the arbitrator’s conduct amounted to a breach of the fair hearing rule. The arbitrator had received an unexpected email after the hearing, attempted verification, and then proceeded after confirming that the appellant had not been informed by Ms Y. The court found no breach of natural justice in proceeding in those circumstances. The appellant’s late reappearance during enforcement proceedings did not retroactively create a procedural unfairness during the arbitration.
Finally, the Court of Appeal addressed prejudice. Even where a procedural irregularity is alleged, setting aside requires more than theoretical unfairness; it requires a showing that the irregularity affected the party’s ability to present its case or otherwise undermined the fairness of the arbitral process. Given the appellant’s non-participation and the court’s findings on notice, the natural justice complaints could not meet the required threshold.
What Was the Outcome?
The Court of Appeal dismissed the appeal and upheld the High Court’s decision to refuse to set aside the Award. Although the Court of Appeal corrected the High Court’s approach on whether the arbitrator implicitly addressed the lack of consideration issue, it still concluded that the infra petita challenge was not available to the appellant because he chose not to participate and did not raise the issue during the arbitration.
Practically, the effect of the decision is that the respondent’s enforcement judgment entered in terms of the Award remained intact. The appellant therefore remained bound by the arbitral award and the court’s refusal to interfere reinforced the finality of arbitral determinations where procedural challenges are not properly grounded.
Why Does This Case Matter?
DEM v DEL is significant for practitioners because it clarifies how Singapore courts will treat setting-aside grounds that are linked to non-participation. The decision underscores that arbitration is not a “spectator sport”: where a party elects not to participate, it faces substantial difficulty in later persuading the court that procedural unfairness occurred. This is especially true for infra petita complaints, which the court treated as unavailable in circumstances where the party could have raised the relevant issue but did not.
The case also provides useful guidance on the relationship between infra petita and natural justice. While infra petita can sometimes be framed in natural justice terms, the Court of Appeal’s reasoning indicates that courts will look beyond labels to the underlying procedural reality. If the party’s own conduct prevented the issue from being properly placed before the tribunal, the court is unlikely to allow the party to repackage the complaint as a fair hearing issue.
For lawyers advising clients in arbitration, the decision reinforces the importance of (i) ensuring that notice arrangements are followed and documented; (ii) promptly engaging with arbitral proceedings; and (iii) raising all relevant issues during the arbitration rather than reserving them for later enforcement or setting-aside litigation. It also highlights that courts may consider prejudice and causation—whether the alleged procedural defect could realistically have changed the outcome—when assessing the merits of setting-aside grounds.
