Summary
DLS v DLT and another matter [2025] SGHC 61 concerns a contractor’s attempt to set aside parts of an ICC tribunal’s “First Partial Award” arising from an interim measures application. The High Court, per Andre Maniam J, addressed a threshold question that often determines the scope of curial review in Singapore arbitration law: whether the tribunal’s impugned decisions were “awards” susceptible to setting aside under s 24 of the International Arbitration Act (IAA), or instead were “orders or directions” made under s 12 of the IAA and therefore not amenable to setting aside.
The court held that the “Monthly Payment” decision was not a setting-aside “award” but an order/direction under s 12 IAA, and dismissed the setting-aside application in respect of that decision. The “Lump Sum Payment” decision was treated differently procedurally and substantively, with the court ultimately not granting setting aside on what was before it at the initial hearing. A further issue was whether the contractor could add “apparent bias” as a new basis for setting aside after the statutory period for setting aside had elapsed, and after an ICC Court challenge had been rejected on the merits. The court’s approach emphasised procedural fairness, finality, and the disciplined use of curial discretion in arbitration-related applications.
What Were the Facts of This Case?
The dispute arose out of a construction project in a foreign country (referred to as “country X”). The claimant in the High Court proceedings (DLS) was the “Contractor” in the arbitration, and the defendant (DLT and another matter) was the “Sub-Contractor”. The parties’ contractual relationship was governed by an agreement between the Contractor and the Sub-Contractor. The ultimate client was anonymised as the “Client”. The arbitration was seated in Singapore and governed by the ICC Rules of Arbitration (in force on 1 January 2021).
In April 2023, the Sub-Contractor commenced arbitration against the Contractor, claiming losses caused by delays in completion of the project. A three-member tribunal was constituted on 13 July 2023. The arbitration then proceeded to an interim measures stage: in November 2023, the Sub-Contractor brought an application seeking “urgent interim measures”. The tribunal’s response to that application was reflected in decisions contained in a “First Partial Award” dated 19 June 2024, with some corrections made on 9 October 2024.
In November 2024, the Contractor filed an originating application (OA 1185) to set aside two decisions in the First Partial Award. The first was the “Monthly Payment” decision at [96(i)], where the tribunal ordered the Contractor to pay the Sub-Contractor a monthly sum of US$172,135.54 until final completion of the project. The monthly payment was intended to cover operational costs and was conditional upon the Sub-Contractor providing a corporate guarantee or other security agreeable to the Contractor to secure repayment if repayment was later ordered.
The second impugned decision was the “Lump Sum Payment” decision at [96(vi)]. The tribunal ordered that a sum of USD 117,339.48 (or equivalent) was owing and due, and that unless the Client released that sum so that it was received by the Sub-Contractor by 14 June 2024, the Contractor would pay that sum to the Sub-Contractor by 28 June 2024. The Contractor’s setting-aside application was supported by two affidavits: (i) an 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 (ii) a lawyer’s affidavit exhibiting an expert opinion on the law of country X and related documents.
Separately, in January 2025, the Contractor sought to challenge the impartiality and independence of one arbitrator before the ICC Court (the “Challenge”). The ICC Court decided on 27 February 2025 that the challenge was admissible but rejected it on the merits. In parallel, on 5 February 2025, the Contractor filed Summons 316 of 2025 (SUM 316) seeking permission to introduce “apparent bias” as a new basis to partially set aside the First Partial Award. SUM 316 was fixed to be heard together with OA 1185 on 14 February 2025, and the High Court adjourned parts of the matter pending the ICC Court’s reasons.
What Were the Key Legal Issues?
The first and most consequential legal issue was the characterisation of the tribunal’s decisions for purposes of Singapore arbitration law. Specifically, the court had to determine whether the “Monthly Payment” decision and the “Lump Sum Payment” decision were “awards” within the meaning of s 2 of the IAA—thereby susceptible to setting aside under s 24 of the IAA and Article 34(1) of the Model Law—or whether they were instead “orders or directions” under s 12 of the IAA, which are excluded from the definition of “award” and are not susceptible to setting aside.
Second, the court had to decide whether the Contractor should be allowed to introduce apparent bias as a new basis for setting aside. This raised questions about (i) whether the contractor was precluded by the statutory time limits for setting aside applications from adding new grounds after the three-month period; and (ii) the effect of the ICC Court’s decision rejecting the challenge on the merits, particularly whether it should constrain or inform the High Court’s discretion to permit the new basis.
Third, once the court determined the procedural permissibility and substantive viability of the apparent bias argument, it had to consider whether the alleged circumstances amounted to apparent bias and, if so, what consequences would follow for the tribunal’s decisions—especially the First Partial Award’s interim payment decisions.
How Did the Court Analyse the Issues?
The High Court began with a threshold analysis of the statutory framework. Under the IAA, an “award” is defined in s 2 as a decision of the arbitral tribunal on the substance of the dispute and includes any interim, interlocutory or partial award, but expressly excludes any order or direction made under s 12. Section 12 empowers tribunals to make orders or give directions, including in relation to interim measures. The court therefore treated the “award” versus “order/direction” distinction as determinative of whether curial setting aside jurisdiction was engaged.
In explaining the distinction, the court relied on the Court of Appeal’s guidance in PT Perusahaan Gas Negara (Persero) TBK v CRW Joint Operation [2015] 4 SLR 364 (“Persero”). The court’s reasoning reflected the principle that not every tribunal decision that affects parties’ rights is a setting-aside “award”. Interim measures and directions made under s 12 are designed to preserve the status quo or manage proceedings, and the IAA’s architecture limits the availability of setting aside as a mechanism to challenge such procedural or interim determinations.
Applying these principles, the court addressed whether the “Monthly Payment” decision was an “award” or an “order/direction”. The Monthly Payment was framed as an ongoing monthly sum intended to cover operational costs, conditional on the provision of security to secure repayment if later ordered. The court treated this as functionally an interim measure decision—closely linked to the tribunal’s handling of the interim measures application—rather than a decision on the substance of the dispute. Accordingly, it concluded that the Monthly Payment decision was not susceptible to setting aside under s 24 IAA because it fell outside the definition of “award” in s 2.
For the “Lump Sum Payment” decision, the court’s analysis was more complex procedurally. At the initial hearing on 14 February 2025, the court dismissed the setting-aside application in respect of the Monthly Payment decision, but did not grant setting aside for the Lump Sum Payment decision on what was then before it. The court adjourned SUM 316 and the remainder of OA 1185 relating to the Lump Sum Payment decision to allow the ICC Court’s reasons on the Contractor’s Challenge to be considered. This reflected a practical arbitration-law consideration: where a party’s apparent bias case depends on facts and reasoning that have been addressed by the arbitral institution’s own challenge mechanism, the High Court may benefit from the ICC Court’s articulated reasons.
On the apparent bias issue, the court considered whether the contractor could introduce a new basis after the statutory period for setting aside had passed. The court’s preliminary observations included two interlocking themes: first, whether the contractor was precluded by time and procedural discipline from expanding the grounds of setting aside; and second, the effect of the ICC Court’s decision rejecting the challenge on the merits. The court did not treat the ICC Court’s rejection as automatically determinative, but it treated it as highly relevant to the exercise of discretion and to the evaluation of whether the new basis was “hopeless” or otherwise inappropriate.
In evaluating apparent bias, the court examined the contractor’s allegations in detail. The allegations centred on non-disclosure and the circumstances of the subject arbitrator’s prior appointment in a “Prior Arbitration” involving claimants that were allegedly related to the claimants in the present arbitration. The court’s analysis included factual inquiries such as when the subject arbitrator knew that the claimants in the two arbitrations were related, and the subject arbitrator’s reasons for non-disclosure. The court then considered whether those circumstances, viewed through the lens of apparent bias, met the threshold for curial intervention.
Finally, the court addressed consequences. Even if apparent bias were established, the court had to consider what effect it would have on the tribunal’s decisions in the First Partial Award—particularly the interim payment decisions. This required the court to connect the bias analysis to the specific decisions sought to be set aside, rather than treating bias as a general ground that automatically invalidates all aspects of the award.
What Was the Outcome?
The High Court dismissed the Contractor’s setting-aside application in respect of the Monthly Payment decision. The court held that the Monthly Payment decision was not an “award” susceptible to setting aside under s 24 IAA, but rather an “order or direction” under s 12 IAA. As a result, the contractor could not obtain the relief sought for that decision through the setting-aside mechanism.
As for the Lump Sum Payment decision, the court did not grant setting aside on what was before it at the initial hearing. The court also dealt with SUM 316 (permission to introduce apparent bias as a new basis) by adjourning it for further hearing after the ICC Court communicated its reasons. The practical effect was that the curial review proceeded in a structured manner: first, by resolving the jurisdictional characterisation of the tribunal’s decisions; and second, by integrating institutional challenge reasoning into the High Court’s assessment of whether apparent bias could be introduced and, if so, whether it would succeed.
Why Does This Case Matter?
DLS v DLT and another matter is significant for practitioners because it reinforces the Singapore courts’ disciplined approach to the “award” versus “order/direction” distinction under the IAA. Parties frequently attempt to characterise interim or procedural determinations as “awards” to unlock setting-aside review. This case illustrates that where a tribunal’s decision is tied to interim measures—especially ongoing payment mechanisms designed to preserve operational continuity or manage risk—the courts will scrutinise whether the decision is truly on the substance of the dispute or instead an interim order/direction excluded from setting-aside jurisdiction.
Second, the case highlights the procedural constraints on expanding grounds for setting aside. Arbitration law values finality and efficiency, and statutory time limits are not merely technical. The court’s willingness to consider apparent bias as a new basis depended on discretionary factors, including whether the basis could and should have been raised earlier, whether it was “hopeless”, and the relevance of the ICC Court’s own decision on the challenge. For counsel, this underscores the importance of front-loading bias and disclosure concerns within the initial setting-aside affidavits, and of coordinating institutional challenges with curial applications.
Third, the decision is a useful reference point for how Singapore courts evaluate apparent bias allegations involving non-disclosure. The court’s emphasis on factual timing (when the arbitrator knew of relationships between parties), the arbitrator’s reasons for non-disclosure, and the link between any bias and the specific decisions sought to be set aside provides a structured template for future submissions.
