Summary

DLS v DLT concerned a Singapore-seated ICC arbitration and the Contractor’s attempt to set aside two decisions contained in a “First Partial Award” dated 19 June 2024 (with corrections). The High Court (Andre Maniam J) addressed a threshold question that often determines the scope of curial review in Singapore arbitration: whether the impugned tribunal decisions were “awards” within the meaning of s 2 of the International Arbitration Act 1994 (IAA), or instead were “orders or directions” made under s 12 IAA (and therefore not susceptible to setting aside under s 24 IAA / Article 34 of the UNCITRAL Model Law).

The court held that the “Monthly Payment” decision was not an “award” but an “order or direction” under s 12 IAA, and therefore dismissed the setting-aside application insofar as it sought to set aside that decision. The court also dealt with the “Lump Sum Payment” decision, and with a further procedural application (SUM 316) seeking permission to introduce “apparent bias” as an additional basis for setting aside—after the statutory time window for setting aside had passed and after the initial supporting affidavits had been filed.

In addition, the court considered the effect of the ICC Court’s separate decision on the Contractor’s challenge to the arbitrator’s impartiality and independence. The High Court’s analysis reflects the Singapore courts’ structured approach to (i) characterising tribunal decisions for the purposes of curial recourse, (ii) maintaining procedural discipline around the grounds and timing for setting aside, and (iii) evaluating allegations of apparent bias within the arbitration framework.

What Were the Facts of This Case?

The parties were engaged in a project in an unnamed country (“Country X”). The claimant, DLS (the “Contractor”), was the main contractor, while the defendant, DLT (the “Sub-Contractor”), was the subcontractor. The engagement was governed by an agreement between the parties. The judgment anonymised the parties’ identifying details to preserve arbitration confidentiality, referring to the Contractor and Sub-Contractor, and also to the ultimate client (“Client”).

In April 2023, the Sub-Contractor commenced arbitration against the Contractor, claiming losses arising from delays in completion of the Project. The arbitration was seated in Singapore and governed by the ICC Rules of Arbitration in force on 1 January 2021. A three-member tribunal was constituted on 13 July 2023.

In November 2023, the Sub-Contractor brought an application seeking “urgent interim measures”. The tribunal’s decisions on that interim measures application were reflected in the “First Partial Award” dated 19 June 2024, with some corrections made on 9 October 2024. The Contractor later sought to set aside two specific decisions contained in that First Partial Award: (a) a “Monthly Payment” decision ordering the Contractor to pay a monthly sum to the Sub-Contractor until final completion of the Project, and (b) a “Lump Sum Payment” decision requiring payment of a specified sum unless the Client released that sum by a particular date.

As part of the setting-aside strategy, the Contractor filed an originating application (OA 1185) in November 2024. It was supported by two affidavits: a first affidavit by the Contractor’s representative (raising breach of natural justice—specifically breach of the “Fair Hearing Rule”—and exceeding the scope of submission to arbitration), and a lawyer’s affidavit exhibiting expert opinion on the law of Country X and related documents. Subsequently, in January 2025, the Contractor also pursued a challenge before the ICC Court concerning the impartiality and independence of one arbitrator (the “subject arbitrator”). After the ICC Court rejected the challenge on the merits, the Contractor filed SUM 316 seeking permission to introduce apparent bias as a new basis for setting aside.

The first and most significant legal issue was jurisdictional and conceptual: whether the tribunal’s “Monthly Payment” and “Lump Sum Payment” decisions were “awards” susceptible to setting aside under s 24 of the IAA (and Article 34(1) of the Model Law), or whether they were “orders or directions” under s 12 IAA, which are excluded from the definition of “award” in s 2 of the IAA and therefore not susceptible to setting aside.

In particular, the court had to interpret the statutory definitions in the IAA and apply the distinction explained by the Court of Appeal in PT Perusahaan Gas Negara (Persero) TBK v CRW Joint Operation [2015] 4 SLR 364 (“Persero”). That distinction is crucial in Singapore arbitration law because it determines whether the court’s supervisory jurisdiction extends to the impugned decision at all.

The second issue concerned procedural fairness and timing: whether the Contractor could introduce “apparent bias” as a new basis for setting aside after the three-month period for applications to set aside awards had passed, and after the initial supporting affidavits had already been filed. Closely related was the effect of the ICC Court’s decision on the arbitrator challenge, and whether the High Court should treat the ICC Court’s reasoning as determinative or merely persuasive in assessing apparent bias allegations.

How Did the Court Analyse the Issues?

Andre Maniam J began with a threshold question: were the decisions the Contractor sought to set aside “awards” under s 2 IAA, or “orders or directions” under s 12 IAA? The IAA defines an “award” as “a decision of the arbitral tribunal on the substance of the dispute” and includes interim, interlocutory or partial awards, but expressly excludes any order or direction made under s 12. Section 12 empowers the tribunal to make orders or give directions for matters including interim measures. The court therefore treated the statutory text as the starting point for characterisation.

The court then relied on the Court of Appeal’s explanation in Persero, which clarifies how provisional or interim decisions should be understood for the purposes of curial review. While the extract provided does not include the full quotation from Persero, the High Court’s approach indicates that it treated the tribunal’s decision as either dealing with the substance of the dispute (and thus potentially an award) or dealing with interim/procedural relief (and thus an order/direction). This is a recurring theme in Singapore arbitration jurisprudence: courts are cautious not to allow parties to circumvent the statutory scheme by relabelling interim measures as awards.

Applying these principles, the court analysed the “Monthly Payment” decision. The decision ordered the Contractor to pay a monthly sum intended to cover the Sub-Contractor’s operational costs per month, and it was conditional upon the Sub-Contractor providing a corporate guarantee or other security agreeable to the Contractor to secure the monthly payments in the event repayment was subsequently ordered. The conditionality and the purpose—covering operational costs pending the final outcome—were central to the court’s characterisation.

On that basis, the court concluded that the Monthly Payment decision was not an “award” but an “order or direction” under s 12 IAA. Consequently, the setting-aside application could not succeed in respect of that decision because s 24 IAA and Article 34 of the Model Law apply only to “awards”. This reasoning underscores that the form of the tribunal’s document (even if contained within a “partial award”) is not determinative; what matters is the legal character of the decision.

As for the “Lump Sum Payment” decision, the court’s analysis proceeded on similar lines but also engaged with additional arguments. The Lump Sum Payment decision required payment of a specified sum by a certain date unless the Client released that sum so it could be received by the Sub-Contractor. The Contractor argued, among other things, that the tribunal exceeded the scope of submission to arbitration and breached natural justice. The court’s extract indicates that it had to decide whether the Lump Sum Payment decision should be set aside, and whether the Contractor could introduce apparent bias as a new basis for setting aside that decision.

The apparent bias issue was addressed through SUM 316. The court first considered a preliminary question: whether the Contractor was precluded from introducing a new basis for setting aside after the three-month period allowed for applications to set aside awards had passed. This reflects the statutory and procedural architecture of setting aside in Singapore: parties must bring their challenges within the prescribed time and with the required supporting material, and courts will not readily permit late expansion of grounds.

However, the court also considered the effect of the ICC Court’s decision on the Contractor’s challenge. The ICC Court had decided that the challenge was admissible but rejected it on the merits. The High Court therefore had to assess whether, and to what extent, the ICC Court’s findings affected the High Court’s own evaluation of apparent bias. The extract indicates that the court treated the ICC Court’s reasons as relevant, but not necessarily conclusive, and then proceeded to evaluate the apparent bias allegations.

In evaluating apparent bias, the court examined the Contractor’s case on (i) alleged failure to disclose, (ii) whether the subject arbitrator’s appointment in a prior arbitration involving related claimants gave rise to apparent bias, and (iii) whether the circumstances of non-disclosure could amount to apparent bias. The court’s analysis included a factual inquiry into when the subject arbitrator knew that the claimants in the two arbitrations were related, and the subject arbitrator’s reasons for non-disclosure. This indicates a careful, fact-sensitive approach rather than a purely formal one.

Finally, the court considered consequences: if there were apparent bias, what would that mean for the decisions in the First Partial Award—particularly the Lump Sum Payment decision. The court’s structure suggests it assessed both the existence of apparent bias and the legal impact on the specific tribunal decisions sought to be set aside.

What Was the Outcome?

The High Court dismissed the Contractor’s application to set aside the Monthly Payment decision. It held that the Monthly Payment decision was not susceptible to setting aside because it was properly characterised as an “order or direction” under s 12 IAA rather than an “award” under s 2 IAA.

As to the Lump Sum Payment decision, the court did not grant setting aside on what was then before it at the time of the 14 February 2025 decision. SUM 316 and the remainder of OA 1185 relating to the Lump Sum Payment decision were adjourned for further hearing after the ICC Court communicated its reasons for rejecting the Contractor’s challenge. The court ultimately proceeded to address the apparent bias basis and its admissibility and merits in the subsequent decision dated 27 March 2025.

Why Does This Case Matter?

DLS v DLT is a useful authority for practitioners because it reinforces the Singapore courts’ disciplined approach to the “award vs order/direction” distinction under the IAA. Parties frequently seek to challenge interim or provisional relief by framing it as part of a partial award. This case illustrates that courts will look beyond labels and document structure to the substance and legal character of the tribunal’s decision, and will deny setting-aside recourse where the decision falls within s 12 IAA.

The case also highlights procedural constraints on expanding grounds for setting aside. The court’s treatment of SUM 316 demonstrates that apparent bias allegations—particularly those not raised in the initial supporting affidavits—face significant hurdles when introduced after the statutory time window. For counsel, this is a reminder to conduct early conflict/disclosure checks and to plead all intended grounds within the prescribed timeframe, or at least to ensure that any later additions are supported by a legally sustainable basis for admissibility.

Finally, the decision is instructive on how Singapore courts may engage with institutional arbitral decisions on challenges to arbitrators. While the ICC Court rejected the challenge on the merits, the High Court still analysed apparent bias allegations, including disclosure issues and the timing of knowledge. This provides a practical roadmap for how apparent bias claims may be evaluated: the focus is on what was disclosed (or not), when the arbitrator knew the relevant facts, and whether the circumstances would lead a fair-minded observer to conclude that there was a real possibility of bias.
