How did this dispute arise, and what was the procedural path to the setting-aside application?

The dispute arose out of two agreements entered into by the parties concerning arrangements for providing two power plants in India, described in the judgment as the “Project”. The respondent invested in the Project in tranches, and the parties’ relationship later deteriorated over issues including the draft Common Loan Agreement, a MAC Notice, and the claimants’ purported termination of the Agreements. The arbitration that followed culminated in an award that the claimants sought to set aside on natural justice grounds. (Para 2, Para 4, Para 12, Para 13, Para 17)

"The dispute arose out of two agreements entered into by the parties concerning arrangements for providing two power plants in India (the “Project”)." — Per Vivian Ramsey IJ, Para 2

The chronology matters because the court’s analysis of the alleged natural justice breaches depended heavily on what was pleaded, what was argued, and what the Tribunal was asked to decide at each stage. The respondent’s investment tranches, the claimants’ objections to the draft Common Loan Agreement, the MAC Notice issued in April 2016, and the May 2016 termination letter formed the factual matrix against which the Tribunal assessed repudiation, affirmation, and related issues. The arbitration itself was commenced in December 2017, and the Award was issued in February 2022. (Para 4, Para 5, Para 6, Para 7, Para 8, Para 9, Para 10, Para 11, Para 12, Para 13, Para 17)

"On 30 May 2016, CUW, on behalf of itself, CUX and CUY issued a letter to the respondent in which it sought to terminate the Agreements (the “May 2016 Letter”) on the basis that the respondent had committed a repudiatory breach of the Agreements and that the repudiation was accepted with effect from 18 April 2016, the date of the MAC Notice." — Per Vivian Ramsey IJ, Para 12

Procedurally, the respondent commenced the arbitration by notice of arbitration on 22 December 2017, referring disputes under the SSA and SHA to arbitration. The Tribunal then issued the Award on 11 February 2022. The claimants’ application before the Singapore International Commercial Court was therefore not a merits appeal, but a challenge to the Award under the statutory setting-aside regime for alleged breaches of natural justice. (Para 13, Para 17, Para 19, Para 20)

"On 22 December 2017, the respondent (as claimant) commenced the Arbitration against the claimants (as respondents) by filing a notice of arbitration (the “Notice of Arbitration”) referring disputes under the SSA and SHA to arbitration." — Per Vivian Ramsey IJ, Para 13

What was the legal basis for the setting-aside application, and what threshold did the court apply?

The application was brought under the International Arbitration Act 1994 and the Model Law, specifically on the basis that a breach of the rules of natural justice occurred in connection with the making of the Award and that the claimants’ rights were prejudiced. The court reproduced the statutory language of section 24, which expressly preserves the Model Law setting-aside grounds and adds the natural justice ground. (Para 20)

"Court may set aside award / 24. Despite Article 34(1) of the Model Law, the General Division of the High Court may, in addition to the grounds set out in Article 34(2) of the Model Law, set aside the award of the arbitral tribunal if –– … (b) a breach of the rules of natural justice occurred in connection with the making of the award by which the rights of any party have been prejudiced." — Per Vivian Ramsey IJ, Para 20

The court emphasised that the threshold for setting aside on natural justice grounds is high and that intervention is exceptional. It also stressed the policy of minimal curial intervention in arbitration, which requires the court to read awards generously and avoid converting complaints about the merits into complaints about procedure. The court’s approach was therefore not to ask whether it would have reached the same substantive conclusions as the Tribunal, but whether the Tribunal had failed to consider essential issues in a way that crossed the high threshold for intervention. (Para 22(a), Para 23(a), Para 23(b), Para 24, Para 25)

"The threshold for a finding of breach of natural justice is a high one and it is only in an “exceptional case” that a court will find that threshold crossed (at [54])." — Per Vivian Ramsey IJ, Para 22(a)

The court also adopted the familiar formulation that, if a failure to consider an issue is alleged, the inference must be clear and virtually inescapable. That standard is important because it prevents a court from lightly inferring procedural unfairness merely because the award does not expressly address every submission or every evidential point. The judgment repeatedly returned to this principle when analysing the four grounds advanced by the claimants. (Para 30, Para 31, Para 32, Para 33)

"the inference – that the arbitrator indeed failed to consider an important pleaded issue – if it is to be drawn at all, must be shown to be clear and virtually inescapable." — Per Vivian Ramsey IJ, Para 30

What were the four grounds on which the claimants sought to set aside the Award?

The court framed the application as four distinct natural justice grounds: the affirmation defence ground, the afterthought argument ground, the clause 16.5 ground, and the inconsistency with the partial award ground. This framing was important because each ground had to satisfy the same basic setting-aside discipline: identify the allegedly essential issue, show that the Tribunal failed to consider it, and demonstrate prejudice. (Para 19, Para 21, Para 22, Para 23)

"The claimants seek to set aside the Award on the following grounds:" — Per Vivian Ramsey IJ, Para 19

The first ground concerned whether the respondent had affirmed the Agreements and therefore could not later terminate them. The second concerned the claimants’ contention that the respondent’s complaint about being named a “promoter” was an afterthought and should have been treated as such. The third concerned clause 16.5, which the claimants said the Tribunal failed to address. The fourth concerned alleged inconsistency between the Award and a partial award. The court dealt with each ground separately, but the reasoning across all four was unified by the same insistence on careful distinction between a failure to consider an issue and a mere disagreement with the Tribunal’s evaluation of it. (Para 40, Para 78, Para 112, Para 130)

"The Tribunal has taken into account all evidence, documents, arguments and submissions even if not referred to expressly, or not set out in full in this Final Award and they are subsumed in the Tribunal’s analysis." — Per Vivian Ramsey IJ, Para 87

In practical terms, the court’s framing meant that the claimants had to do more than point to silence or brevity in the Award. They had to show that the Tribunal had omitted an essential pleaded issue, not merely that it had not written out every step of its reasoning in the way the claimants preferred. That distinction was decisive in the court’s treatment of the affirmation defence and the afterthought argument, and it also informed the court’s rejection of the remaining grounds. (Para 30, Para 31, Para 71, Para 109)

Why did the court reject the affirmation defence ground?

The claimants argued that the affirmation defence was an essential issue because, if the respondent had affirmed the Agreements after the alleged repudiatory conduct, it could not later terminate them. They said the Tribunal failed to consider this defence when determining the respondent’s wrongful termination claim. The respondent answered that the Tribunal did consider the issue, and that the claimants’ complaint was really an attempt to repackage a merits disagreement as a natural justice challenge. (Para 40, Para 41, Para 42, Para 51, Para 52)

"The claimants submit that the affirmation defence was an essential issue to be considered by the Tribunal in its determination of the respondent’s wrongful termination claim. Nonetheless, it submits that the Tribunal failed to consider this affirmation defence." — Per Vivian Ramsey IJ, Para 40

The court examined the Award and the surrounding submissions and concluded that the Tribunal had in fact considered the relevant issues. It noted that the Tribunal addressed the respondent’s case on continuing or anticipatory breaches and the claimants’ response, including the factual and legal context in which affirmation was raised. The court also observed that the claimants’ affirmation point had been raised late, in reply closing submissions, and was not properly articulated either factually or legally. In those circumstances, the court held that it could not criticise the Tribunal on natural justice grounds for not dealing with a late and inadequately developed point as though it were a central pleaded issue. (Para 53, Para 54, Para 55, Para 56, Para 57, Para 58, Para 59, Para 60, Para 61, Para 62, Para 63, Para 64, Para 65, Para 66, Para 67, Para 68, Para 69, Para 70, Para 71)

"I do not consider that the claimants can criticise the Tribunal on natural justice grounds for not dealing with an affirmation defence raised at a late stage in the reply closing submissions and not properly articulated either as to the factual or legal basis for that contention." — Per Vivian Ramsey IJ, Para 71

The court’s conclusion was reinforced by the way the Award itself dealt with the continuing or anticipatory breaches in February 2017 and June 2018. The Tribunal’s analysis showed that it was alive to the sequence of events and the legal consequences of the parties’ conduct. The court therefore rejected the suggestion that the Tribunal had ignored the affirmation defence. It held, in terms, that the claimants had not established a breach of natural justice warranting setting aside on this ground. (Para 68, Para 69, Para 70, Para 71, Para 72, Para 73)

"On that basis, I reject the claimants’ application to set aside the Award on the basis of the Affirmation Defence Ground." — Per Vivian Ramsey IJ, Para 73

How did the court deal with the “afterthought” argument about the respondent being named a “promoter”?

The second major issue concerned the respondent’s objection to being named as a “promoter” and whether that objection was an afterthought. The claimants argued that the afterthought point was an essential issue because it went to whether the respondent’s concerns were unreasonable and whether those concerns evidenced an intention not to perform its obligations under the Agreements. The respondent replied that the issue was not a free-standing legal principle but a factual and contextual matter about the legal consequences of being named a promoter under Indian law. (Para 78, Para 79, Para 80, Para 95, Para 96)

"The claimants submit that the Afterthought Argument was an essential issue that had to be decided by the Tribunal in its determination of whether the respondent’s alleged concerns regarding being named as a “promoter” were unreasonable and evidenced an intention not to perform its obligations under the Agreements." — Per Vivian Ramsey IJ, Para 78

The court reviewed the Tribunal’s treatment of the promoter issue and found that it had plainly been alive throughout the arbitration. The judgment records that the issue was “appreciated by all sides to be very much a live issue,” and that the Tribunal referred to expert evidence on what a promoter meant under Indian law. The court also noted that the Tribunal considered the issue in the context of the parties’ submissions and the factual matrix, including the respondent’s concerns and the claimants’ response. This was enough to defeat the allegation that the Tribunal had failed to consider an essential issue. (Para 100, Para 101, Para 102, Para 103, Para 104, Para 105, Para 106, Para 107, Para 108, Para 109)

"The issue relating to the “promoter” was “appreciated by all sides to be very much a live issue”." — Per Vivian Ramsey IJ, Para 109

The court therefore rejected the claimants’ attempt to characterise the matter as an unaddressed afterthought argument. It accepted the respondent’s submission that, in context, the complaint was not a pure legal proposition but part of the broader factual and expert-evidence dispute about the significance of promoter status. The court’s reasoning again reflected the distinction between a tribunal’s failure to consider a point and a tribunal’s decision not to adopt the party’s preferred framing of that point. (Para 95, Para 96, Para 97, Para 98, Para 99, Para 100, Para 101, Para 102, Para 103, Para 104, Para 105, Para 106, Para 107, Para 108, Para 109)

"The respondent says that, in its proper context, the Afterthought Argument is not an argument which is grounded in legal principle or reasoning." — Per Vivian Ramsey IJ, Para 95

What did the court say about the Tribunal’s treatment of the evidence and submissions?

The court’s analysis of the alleged natural justice breaches was closely tied to the evidential record. It considered the pleadings, opening and closing submissions, witness evidence, expert evidence on Indian law, and the Tribunal’s own findings in the Award. The court did not treat the Award as a stand-alone document divorced from the arbitration record; instead, it assessed whether the Tribunal had engaged with the issues in substance across the whole proceeding. (Para 22, Para 23, Para 24, Para 25, Para 26, Para 27, Para 28, Para 29, Para 30)

"At [433] of the Award, the Tribunal referred to the opinion of Ms [FFF], the respondent’s expert witness, on what a “promoter” meant under Indian law." — Per Vivian Ramsey IJ, Para 102

That approach mattered because the claimants’ complaints depended on selective readings of the Award. The court repeatedly emphasised that an arbitral tribunal is not required to address every submission expressly, and that silence on a particular point does not automatically mean the point was ignored. The Tribunal’s own statement that it had taken into account all evidence, documents, arguments and submissions, even if not referred to expressly, supported the court’s conclusion that the Award should be read as a whole and not parsed for omissions in isolation. (Para 87, Para 88, Para 89, Para 90, Para 91, Para 92, Para 93, Para 94)

"The Tribunal has taken into account all evidence, documents, arguments and submissions even if not referred to expressly, or not set out in full in this Final Award and they are subsumed in the Tribunal’s analysis." — Per Vivian Ramsey IJ, Para 87

The court also relied on the Tribunal’s treatment of the continuing or anticipatory breaches in February 2017 and June 2018 as evidence that the Tribunal had engaged with the sequence of events and the legal consequences of the parties’ conduct. This was particularly important to the affirmation defence ground, because the Tribunal’s analysis of later conduct showed that it had not simply overlooked the possibility that the respondent’s rights might have been affected by subsequent events. (Para 68, Para 69, Para 70, Para 71, Para 72)

How did the court apply the “clear and virtually inescapable” inference standard?

The court treated the “clear and virtually inescapable” standard as a practical safeguard against over-reading arbitral awards. A party alleging that a tribunal failed to consider an issue must show more than the absence of an express discussion; it must demonstrate that the only realistic inference is that the tribunal overlooked the issue altogether. This is a demanding standard, and the court applied it rigorously to each of the claimants’ grounds. (Para 30, Para 31, Para 32, Para 33, Para 34)

"the inference – that the arbitrator indeed failed to consider an important pleaded issue – if it is to be drawn at all, must be shown to be clear and virtually inescapable." — Per Vivian Ramsey IJ, Para 30

On the affirmation defence, the court found that the inference of non-consideration was not remotely clear or inescapable because the Tribunal had addressed the surrounding factual and legal issues, including continuing breaches and the parties’ conduct over time. On the afterthought argument, the same standard failed because the promoter issue was plainly live, was addressed through expert evidence, and was part of the Tribunal’s analysis. The court therefore refused to infer a breach of natural justice from the mere fact that the Award did not adopt the claimants’ preferred terminology or structure. (Para 68, Para 69, Para 70, Para 71, Para 102, Para 103, Para 104, Para 105, Para 106, Para 107, Para 108, Para 109)

"The issue relating to the “promoter” was “appreciated by all sides to be very much a live issue”." — Per Vivian Ramsey IJ, Para 109

This approach is consistent with the court’s broader insistence that arbitral awards should be read generously. The judgment makes clear that a tribunal’s reasons need not be exhaustive, and that a court should not infer procedural unfairness merely because the award is concise or because it does not expressly answer every argument. The court’s application of the standard therefore protected the finality of arbitration while preserving intervention for truly exceptional cases. (Para 22(a), Para 23(a), Para 24, Para 25, Para 30)

What was the significance of the court’s treatment of the partial award and the remaining grounds?

Although the extracted material is more detailed on the affirmation defence and afterthought argument, the judgment makes clear that the claimants advanced four grounds in total, including a clause 16.5 ground and an inconsistency-with-partial-award ground. The court’s overall dismissal of the application indicates that none of the grounds met the stringent natural justice threshold. The reasoning applied to the first two grounds—careful reading of the Award, generous construction, and insistence on prejudice—also governed the court’s treatment of the remaining grounds. (Para 19, Para 21, Para 22, Para 23, Para 130)

"The claimants seek to set aside the Award on the following grounds:" — Per Vivian Ramsey IJ, Para 19

Because the extraction does not provide the full text of the court’s analysis on clause 16.5 or the partial award inconsistency, it is not possible to reconstruct those sections in greater detail without risking invention. What can be said, on the basis of the available text, is that the court did not accept any of the grounds as establishing a breach of natural justice. The final disposition therefore confirms that the Tribunal’s Award stood, and that the claimants’ attempt to re-open the arbitral outcome through a setting-aside application failed in its entirety. (Para 130, Para 131, Para 132, Para 133)

"On that basis, I reject the claimants’ application to set aside the Award on the basis of the Affirmation Defence Ground." — Per Vivian Ramsey IJ, Para 73

What legal authorities and principles did the court rely on?

The judgment drew on a line of Singapore arbitration authorities dealing with natural justice, minimal curial intervention, and the distinction between a tribunal’s failure to consider an issue and a mere error of law or fact. The extracted material identifies authorities including Soh Beng Tee & Co Pte Ltd v Fairmount Development Pte Ltd, BZV v BZW and another, BZW and another v BZV, Glaziers Engineering Pte Ltd v WCS Engineering Construction Pte Ltd, Front Row Investment Holdings (Singapore) Pte Ltd v Daimler South East Asia Pte Ltd, AKN and another v ALC and others and other appeals, TMM Division Maritima SA de CV v Pacific Richfield Maine Pte Ltd, AQU v AQV, SEF Construction Pte Ltd v Skoy Connected Pte Ltd, BLC and others v BLB and another, L W Infrastructure Pte Ltd v Lim Chin San Contractors Pte Ltd and another appeal, and CDM and another v CDP. (Para 22, Para 23, Para 24, Para 25, Para 26, Para 27, Para 28, Para 29, Para 30)

"The grounds for setting aside an award are to be construed and applied bearing in mind the policy of minimal curial intervention in arbitration." — Per Vivian Ramsey IJ, Para 23(a)

The court also referred to Union of India v Kesar Singh in the context of affirmation under Indian law, and to statutory materials including section 24(b) of the International Arbitration Act and Article 34(2)(b)(ii) of the Model Law. The significance of these authorities was not to expand the scope of judicial review, but to reinforce the narrowness of the setting-aside jurisdiction and the need for a disciplined, issue-specific analysis. (Para 20, Para 22, Para 23, Para 24, Para 25, Para 26, Para 27, Para 28, Para 29, Para 30)

"Once a contract is affirmed, later repudiation is not allowed." — Per Vivian Ramsey IJ, Para 22(b) / authority cited in the extraction

In practical terms, the authorities supported the court’s conclusion that a party cannot succeed by pointing to an award’s lack of express discussion if the issue was in substance considered. They also supported the proposition that a tribunal’s reasons are to be read holistically, and that a court should not interfere unless the alleged omission is both real and prejudicial. That framework explains why the claimants’ arguments, though carefully presented, did not clear the high bar for setting aside. (Para 22(a), Para 23(a), Para 30, Para 31, Para 32, Para 33)

Why does this case matter for arbitration practitioners?

This case is a strong reaffirmation of Singapore’s pro-arbitration, minimal-intervention approach to setting aside awards. It shows that a party seeking to invoke natural justice must identify a genuinely essential issue that the tribunal failed to consider, not merely an issue that was not addressed in the exact way the party wanted. The judgment is especially useful for practitioners because it illustrates how the court will examine the arbitration record as a whole, including pleadings, submissions, evidence, and the award itself, before drawing any inference of procedural unfairness. (Para 22(a), Para 23(a), Para 30, Para 87)

"The threshold for a finding of breach of natural justice is a high one and it is only in an “exceptional case” that a court will find that threshold crossed (at [54])." — Per Vivian Ramsey IJ, Para 22(a)

The case also demonstrates the danger of raising a point late and then characterising the tribunal’s failure to address it expressly as a denial of natural justice. The court was unwilling to treat a late, underdeveloped affirmation defence as an essential issue that the Tribunal was obliged to analyse in detail. That has obvious practical implications for arbitration advocacy: parties must plead, develop, and preserve their key points clearly and early if they wish to rely on them later. (Para 40, Para 41, Para 42, Para 71)

"I do not consider that the claimants can criticise the Tribunal on natural justice grounds for not dealing with an affirmation defence raised at a late stage in the reply closing submissions and not properly articulated either as to the factual or legal basis for that contention." — Per Vivian Ramsey IJ, Para 71

Finally, the judgment is a reminder that expert evidence and contextual factual disputes can be central to whether an issue was “live” before the tribunal. The promoter issue was not treated as an abstract legal afterthought; it was embedded in the evidence and submissions, and the court was prepared to rely on that context to reject the setting-aside challenge. For arbitration users, the lesson is clear: if an issue is truly central, it should be made unmistakably central in the record. (Para 95, Para 96, Para 100, Para 102, Para 109)
