Summary
This dispute concerns a complex arbitration involving Vietnam Oil and Gas Group (PVN) and Joint Stock Company (Power Machines). The core of the appellate proceedings, CA 48 and CA 49, centered on the validity of specific findings within a Final Award and the subsequent remission order issued by the High Court in OA 346. The parties contested the tribunal's jurisdiction and the procedural propriety of the award, specifically regarding the application of the International Arbitration Act and relevant provisions of the UK Arbitration Act.
The Court of Appeal, led by Chief Justice Sundaresh Menon, ultimately ruled in favor of PVN. The Court dismissed PM’s appeal (CA 49) and allowed PVN’s appeal (CA 48), effectively setting aside the High Court’s remission order. Furthermore, the Court vacated paragraph 548 of the Final Award and any consequential findings, signaling a strict judicial approach to the scope of arbitral awards and the limits of court-ordered remission. This decision reinforces the appellate court's role in maintaining the integrity of arbitral outcomes by ensuring that awards remain within the bounds of the tribunal's mandate and the governing statutory framework.

What Were the Facts of This Case?
The dispute centers on an Engineering, Procurement, and Construction (EPC) Contract entered into around 2013 between Vietnam Oil and Gas Group (PVN) and a consortium involving Joint Stock Company (Power Machines – ZTL, LMZ, Electrosila Energomachexport) (PM). The contract governed the construction of a thermal power plant in Vietnam and was subject to Vietnamese law, with arbitration seated in Singapore under SIAC rules.
The relationship between the parties deteriorated following the imposition of US Sanctions on PM in January 2018. This designation caused significant operational disruption, as many of PM's subcontractors suspended their performance due to the legal risks associated with the sanctions. Consequently, PM sought to terminate the EPC Contract, citing both force majeure and non-payment by PVN as grounds for termination.
PVN contested the validity of these termination notices, arguing that the US Sanctions did not qualify as a force majeure event under the contract. Furthermore, PVN asserted that PM's initial attempt to terminate the contract constituted a wrongful repudiation, which invalidated subsequent attempts to terminate for non-payment.
The arbitral tribunal ultimately determined that while the US Sanctions did not meet the contractual definition of force majeure, the act of issuing the termination notice was sufficient under Vietnamese law to end the contractual relationship. This led to complex legal challenges regarding the tribunal's jurisdiction and the application of natural justice, which were subsequently brought before the Singapore courts.
What Were the Key Legal Issues?
The appeal in Vietnam Oil and Gas Group v Joint Stock Company (Power Machines – ZTL, LMZ, Electrosila Energomachexport) [2025] SGCA 50 centers on the procedural fairness of an arbitral tribunal's decision-making process and the limits of its jurisdiction under the UNCITRAL Model Law.
- Breach of the Fair Hearing Rule: Whether the Tribunal’s reliance on a chain of reasoning not advanced or addressed by either party, specifically regarding the legal effect of a 'Second Notice' of termination, deprived the appellant of a fair hearing.
- Excess of Jurisdiction: Whether the Tribunal’s determination of issues outside the scope of the parties' submissions constituted an excess of jurisdiction under Article 34(2)(a)(iii) of the Model Law.
- Prejudice Requirement: Whether a breach of natural justice requires proof that the tribunal would have reached a different result, or merely that the breach denied the parties the benefit of arguments that had a 'real as opposed to a fanciful chance' of affecting the outcome.
How Did the Court Analyse the Issues?
The Court of Appeal focused primarily on the 'fair hearing rule,' affirming that an arbitral tribunal must not base its decision on a chain of reasoning that the parties had no reasonable opportunity to address. The Tribunal had concluded that a 'Second Notice' of termination superseded an earlier 'First Notice,' a theory neither party had pleaded or argued.
The Court relied on Soh Beng Tee & Co Pte Ltd v Fairmount Development Pte Ltd [2007] 3 SLR(R) 86 to reiterate that a breach of natural justice must result in prejudice. However, it clarified, citing L W Infrastructure Pte Ltd v Lim Chin San Contractors Pte Ltd [2013] 1 SLR 125, that the test is whether the breach denied the tribunal the benefit of arguments that had a 'real as opposed to a fanciful chance of making a difference to his deliberations.'
The Court rejected the respondent's argument that the experts had sufficient opportunity to address the issue. It found that the questions posed to the experts were 'somewhat vague' and failed to address the specific scenario of a 'wrongfully issued' initial notice. Consequently, the Tribunal’s conclusion lacked a 'sufficient nexus' to the parties' cases.
Regarding the factual findings, the Court noted that the Tribunal’s conclusion on the respondent's intention to supersede the First Notice was 'contrary to the factual reality' presented, as the respondent had explicitly pleaded the opposite. This lack of nexus rendered the Tribunal's reasoning procedurally unfair.
On the issue of jurisdiction under Article 34(2)(a)(iii) of the Model Law, the Court referenced PT Prima International Development v Kempinski Hotels SA [2012] 4 SLR 98, emphasizing that a tribunal derives its authority from the parties' consent. While the Court acknowledged the two-stage inquiry for excess of jurisdiction established in CJA v CIZ [2024] 5 SLR 706, it ultimately found it unnecessary to make a definitive ruling on the jurisdictional point, having already set aside the award based on the breach of the fair hearing rule.
What Was the Outcome?
The Court of Appeal allowed the appeal by Vietnam Oil and Gas Group (PVN) and dismissed the appeal by Power Machines (PM). The Court determined that the trial judge erred in ordering the remission of the arbitral award, finding that the tribunal's breach of the fair hearing rule was too severe to be cured by remission.
132 For these reasons, we dismiss PM’s appeal in CA 49, and allow PVN’s appeal in CA 48. We set aside the Judge’s remission order in OA 346, and we set aside para 548 of the Final Award as well as any other parts of the Final Award consequential to para 548. We award costs in the aggregate sum of $140,000 to PVN by way of costs in respect of both appeals together with reasonable disbursements which are to be agreed or, failing that, to be settled by us.
The Court set aside the impugned paragraph of the Final Award and all consequential findings, effectively precluding the tribunal from further consideration of the tainted issues. Costs were awarded to PVN in the aggregate sum of $140,000.
Why Does This Case Matter?
The case establishes that remission of an arbitral award is inappropriate where the breach of natural justice is serious, material, and gives rise to a reasonable suspicion of prejudgment. The Court clarified that even if an issue is technically severable, its importance must be examined in the context of the entire award; if the tribunal's decision is fundamentally disconnected from the parties' arguments and evidence, remission may be futile or unfair.
This decision builds upon the principles in CAJ v CAI and Wan Sern regarding the limits of remission, specifically where remission would necessitate an unfair amendment of pleadings or where the tribunal has demonstrated a lack of receptiveness to rectifying its own procedural errors. It distinguishes cases where remission is a viable remedy for minor procedural slips, emphasizing that the fair-minded observer's confidence in the tribunal is the ultimate touchstone.
For practitioners, this case serves as a critical warning against relying on remission as a 'safety net' for flawed awards. In litigation, it underscores the necessity of ensuring that arbitral findings are tethered to the parties' pleaded cases and evidence. Transactionally, it highlights the risks of complex EPC contracts where liability findings are contingent on specific, potentially erroneous, arbitral interpretations that may be difficult to challenge or rectify once the award is issued.
Practice Pointers
- Ensure Expert Reports Address Contingencies: Do not rely on experts to 'infer' the scope of their instructions. If a tribunal's potential finding hinges on a specific legal premise (e.g., a wrongful notice), explicitly draft questions for experts that mandate analysis under that specific premise.
- Monitor the 'Nexus' of Reasoning: Counsel must proactively flag when a tribunal appears to be drifting toward a 'third way' not argued by either party. If the tribunal poses vague questions to experts, seek clarification immediately to avoid a breach of natural justice.
- Pleadings as a Shield: Use the parties' pleadings to define the boundaries of the tribunal's mandate. If a party expressly pleads that a notice was not intended to supersede a prior one, the tribunal cannot unilaterally invent a contrary factual intent without violating the right to be heard.
- Challenge 'Implicit' Findings: Tribunals often rely on 'implicit' intentions to bridge gaps in evidence. Counsel should challenge these as 'surprising' findings that deprive the parties of the opportunity to lead rebuttal evidence or cross-examine on the specific point.
- Strategic Use of Lists of Issues: While lists of issues are not exhaustive, use them to anchor the tribunal to the parties' cases. If the tribunal's reasoning departs from the core issues identified, use this as a basis for challenging the award on the ground of lack of fair opportunity to address the case.
- Distinguish 'Remission' from 'Setting Aside': Understand that where a breach of natural justice is so material that it undermines the fair-minded observer's confidence in the tribunal's impartiality, remission is inappropriate; the only remedy is to set aside the affected parts of the award.
Subsequent Treatment and Status
As this judgment was delivered in October 2025, it is a very recent decision of the Singapore Court of Appeal. Consequently, it has not yet been substantively cited or applied in subsequent case law. It currently stands as the definitive authority on the limits of a tribunal's power to adopt a 'third way' of reasoning that lacks a sufficient nexus to the parties' pleaded cases.
The decision reinforces the established principles regarding natural justice in arbitration, specifically the requirement that parties must have a reasonable opportunity to address the issues upon which the tribunal intends to base its decision. It serves as a cautionary tale against tribunals attempting to 'fill the gaps' in expert evidence without giving parties the chance to respond to the specific legal or factual premises being adopted.
