Summary
This dispute concerns complex arbitration proceedings between Vietnam Oil and Gas Group (PVN) and Joint Stock Company (Power Machines). The central issue revolved around the validity and enforceability of specific paragraphs within a Final Award, specifically paragraph 548, and the appropriateness of a remission order issued by the lower court. The appellate proceedings involved cross-appeals (CA 48 and CA 49) where the parties contested the scope of the tribunal's authority and the subsequent judicial intervention via the International Arbitration Act.
The Court of Appeal, led by Chief Justice Sundaresh Menon, ultimately ruled in favor of PVN. The Court dismissed Power Machines' appeal and allowed PVN's appeal, effectively setting aside the High Court's remission order and the impugned paragraph 548 of the Final Award. This decision underscores the strict judicial approach to the finality of arbitral awards and the limited circumstances under which courts will intervene to remit matters back to a tribunal. The judgment serves as a significant reminder of the high threshold required for challenging arbitral findings under the International Arbitration Act, reinforcing the pro-arbitration stance of the Singapore judiciary.

What Were the Facts of This Case?
The dispute arises from 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 contained an arbitration agreement stipulating that disputes be resolved in Singapore under SIAC rules.
The relationship between the parties deteriorated following the imposition of US Sanctions on PM in 2018, which prevented US persons from engaging in transactions with the company. This led to the suspension of work by many of PM's subcontractors and prompted PM to claim that the sanctions constituted a force majeure event under the contract, a claim PVN vehemently contested.
Following failed negotiations regarding payment arrangements that would comply with the sanctions, PM attempted to terminate the contract twice: first, citing force majeure, and second, citing PVN's failure to pay outstanding invoices. PVN argued that the first notice was a wrongful repudiation of the contract, which invalidated the subsequent termination notice.
The arbitral tribunal ultimately ruled that while the force majeure claim was unsubstantiated, the contract was effectively terminated under Vietnamese law due to the issuance of the notices. The case reached the Singapore courts as both parties sought to challenge the tribunal's findings on jurisdiction, natural justice, and the validity of the termination notices.
What Were the Key Legal Issues?
The Court of Appeal addressed critical questions regarding the limits of an arbitral tribunal's discretion in formulating its own chain of reasoning and the jurisdictional boundaries of arbitral awards.
- Breach of the Fair Hearing Rule: Whether the Tribunal’s reliance on a chain of reasoning neither pleaded nor argued by the parties, and which contradicted the parties' own positions, denied the respondent a fair opportunity to present its case.
- Excess of Jurisdiction under Article 34(2)(a)(iii) of the Model Law: Whether the Tribunal exceeded its mandate by deciding a pivotal issue—the legal effect of a second notice of termination on a wrongful first notice—that was outside the scope of the parties' submissions.
- Prejudice in Natural Justice Claims: Whether a breach of the fair hearing rule requires the court to be satisfied that the tribunal would have reached a different result, or merely that the breach deprived the party of arguments with a real chance of making a difference.
How Did the Court Analyse the Issues?
The Court of Appeal focused on the 'fair hearing rule,' emphasizing that a tribunal cannot adopt a chain of reasoning that lacks a sufficient nexus to the parties' cases. The Court held that the Tribunal's finding in paragraph 548 of the Final Award—that a second notice of termination could override an invalid first notice—was a 'pivotal issue' that neither party had anticipated or addressed.
Relying on Phoenixfin, the Court noted that parties must have the chance to 'question the evidence produced in support of the issue as well as have the chance to itself introduce relevant rebuttal evidence.' Because the Tribunal’s conclusion on Vietnamese law and the factual intention of the parties was at odds with the entire course of the arbitration, the Court found a clear breach of natural justice.
Regarding the threshold for prejudice, the Court rejected the appellant's argument that the breach was harmless. Citing L W Infrastructure Pte Ltd v Lim Chin San Contractors Pte Ltd [2013] 1 SLR 125, the Court clarified that the inquiry is whether the breach resulted in the tribunal being 'denied the benefit of arguments or evidence that had a real as opposed to a fanciful chance of making a difference.'
The Court further analyzed the jurisdictional challenge under Article 34(2)(a)(iii) of the Model Law. It reiterated that while tribunals have broad discretion, they derive authority only from the consent of the parties (Bloomberry Resorts and Hotels Inc v Global Gaming Philippines LLC [2021] 2 SLR 1279). The Court distinguished between an 'erroneous exercise' of power, which is an error of law, and a 'purported exercise' of a power not possessed, which warrants setting aside the award.
Ultimately, the Court affirmed the lower court's finding of a breach of the fair hearing rule. It concluded that the Tribunal’s failure to give notice of its intended reasoning prevented the respondent from adducing expert evidence on the specific scenario contemplated, thereby prejudicing the outcome of the arbitration.
What Was the Outcome?
The Court of Appeal allowed the appeal by Vietnam Oil and Gas Group (PVN) and dismissed the cross-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 remittal.
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 ordered that paragraph 548 of the Final Award, along with all consequential findings, be set aside. Costs were awarded to PVN in the aggregate sum of $140,000 plus reasonable disbursements.
Why Does This Case Matter?
This case establishes that the court will decline to remit an arbitral award where the breach of natural justice is so material that it undermines confidence in the tribunal's ability to reach a fair conclusion. The Court of Appeal clarified that remission is inappropriate if it necessitates an amendment of pleadings in a manner that would be manifestly unfair to the opposing party, or if the tribunal has demonstrated a degree of prejudgment that renders a fair rehearing unlikely.
The decision builds upon the principles established in CAJ v CAI and Wan Sern regarding the limitations of remission. It clarifies that while time and cost savings are relevant considerations, they are peripheral when the defect in the arbitral process is fundamental. The court explicitly departed from the approach in Soh Beng Tee to the extent that it suggested isolated issues could be remitted without considering the impact on the award's overall integrity.
For practitioners, this judgment serves as a critical warning regarding the risks of tactical pleading and the high threshold for seeking remission. In litigation, counsel must ensure that arguments are clearly tethered to the parties' pleadings, as the court will not permit a party to shift its case during remission to accommodate a tribunal's erroneous findings. Transactionally, this reinforces the importance of ensuring that arbitral tribunals adhere strictly to the scope of arguments presented by the parties to avoid the finality of the award being compromised.
Practice Pointers
- Avoid 'Surprise' Reasoning: Tribunals must ensure that any chain of reasoning adopted has a sufficient nexus to the parties' pleaded cases. If a tribunal intends to rely on a legal theory not advanced by either party, it must invite submissions to avoid a breach of natural justice.
- Drafting Expert Questions: When drafting joint expert reports, ensure questions are explicitly premised on the specific factual scenarios in dispute (e.g., 'assuming the first notice is found to be wrongful'). Vague or generic questions lead to expert responses that may not address the tribunal's eventual findings.
- Managing Pleadings: Parties should be wary of relying on 'catch-all' issues in lists of issues. The Court of Appeal emphasized that even if a general issue (e.g., 'whether the contract was terminated') is listed, it does not grant the tribunal license to adopt a novel legal theory that neither party anticipated or had the opportunity to address.
- Evidential Burden on Intent: If a party's case is that a subsequent notice of termination supersedes an earlier one, this must be pleaded and supported by evidence. A tribunal cannot unilaterally impute an 'intention' to a party that contradicts their express pleadings.
- Challenging Awards: Remission is not a 'cure-all' for procedural unfairness. Where a tribunal's reasoning suggests prejudgment or requires the parties to fundamentally amend their cases to address a new theory, the court may prefer to set aside the offending portion of the award rather than remit it.
- Proactive Expert Management: If an expert report is ambiguous or fails to address a critical contingency, counsel must seek clarification or supplemental reports before the hearing concludes to prevent the tribunal from filling the 'evidentiary gap' with its own conclusions.
Subsequent Treatment and Status
As the judgment in Vietnam Oil and Gas Group v Joint Stock Company ([2025] SGCA 50) was delivered on 10 October 2025, it is a very recent decision. Consequently, it has not yet been substantively cited or applied in subsequent Singapore High Court or Court of Appeal jurisprudence.
The decision serves as a significant clarification of the limits of a tribunal's inquisitorial powers in arbitration, reinforcing the principles established in Phoenixfin regarding the right to address evidence and arguments. It is expected to be treated as a leading authority on the threshold for 'material' breaches of natural justice arising from a tribunal's departure from the parties' pleaded cases.
