Summary
In CAJ & Anor v CAI ([2021] SGCA 102), the Court of Appeal upheld the High Court’s decision to partially set aside an ICC arbitral award arising from a construction dispute. The central controversy concerned the tribunal’s acceptance of an “extension of time” (EOT) defence that had not been pleaded, not featured in the Terms of Reference or List of Issues, and was raised only for the first time in the appellants’ written closing submissions.
The Court of Appeal emphasised that Singapore courts intervene in arbitration awards only on limited, statutorily-prescribed grounds and with restraint. Nonetheless, where the tribunal decides an issue outside the scope of the parties’ submissions and does so in a manner that breaches natural justice, curial intervention is warranted. The Court agreed that the tribunal exceeded its jurisdiction and breached natural justice, and therefore dismissed both appeals: one on the merits and the other on costs.
What Were the Facts of This Case?
The dispute arose from two construction agreements for the construction of a polycrystalline silicon plant (the “Plant”). The respondent’s subsidiary owned the Plant, while the appellants were the contractors responsible for constructing it. During construction, problems emerged concerning excessive vibrations in compressors located in the hydrogen unit. These issues remained unresolved as at the contractual date of mechanical completion.
Rectification works were carried out later in a piecemeal manner pursuant to instructions issued by the respondent’s subsidiary (referred to in the judgment as the “Admitted Instruction”). After the works, the respondent’s subsidiary commenced arbitration against the appellants. The respondent was subsequently joined as assignee of the subsidiary’s claim.
The arbitration was seated and conducted in Singapore under the auspices of the International Chamber of Commerce, pursuant to the 2012 ICC Rules. The tribunal comprised three members. The respondent sought liquidated damages for delay, alleging that the appellants caused a 144-day delay in achieving mechanical completion due to the excessive vibrations in the compressors within the hydrogen unit.
In the arbitration, the appellants advanced two main lines of defence. First, they argued that mechanical completion had been achieved on time because the vibrations did not materially affect the operation or safety of the Plant. Second, they contended that any delay was caused by the Admitted Instruction, such that the respondent had waived its right to liquidated damages or was estopped from claiming them (the “Estoppel Defence”). Importantly, the appellants’ pleadings did not assert that they were contractually entitled to an extension of time to reduce liquidated damages. The EOT defence was based on General Condition 40 (“GC 40”), which provided for an extension of time if delay was by reason of any act or omission of, or default or breach of the agreements by, the respondent’s subsidiary.
What Were the Key Legal Issues?
The Court of Appeal had to determine whether the tribunal’s decision to accept the EOT defence and grant an extension of time was legally permissible in the context of the arbitration’s procedural framework and the parties’ submissions. This required assessing whether the tribunal exceeded its jurisdiction by deciding an issue that was not within the scope of the parties’ submission to arbitration.
Second, the Court had to evaluate whether the tribunal’s approach breached natural justice. Natural justice in this context focuses on whether a party was given a fair and reasonable opportunity to present its case and respond to the other side’s case. The High Court had found two distinct natural justice breaches: a primary breach relating to the respondent’s lack of opportunity to respond to the EOT defence, and a secondary breach relating to the tribunal’s reliance on its own “professed experience” without giving the parties an opportunity to address what that experience entailed.
Finally, the Court of Appeal also addressed the appropriate recourse and the practical effect of setting aside the award portion relating to the EOT defence, including consequential orders and costs.
How Did the Court Analyse the Issues?
The Court of Appeal began by reiterating the narrow scope for judicial intervention in arbitration awards under Singapore law. While the exact statutory provisions were not reproduced in the extract, the Court’s reasoning reflects the well-established principle that set-aside applications are confined to limited, statutorily-prescribed grounds. Even then, courts exercise their powers with restraint, setting aside awards only when good reason exists.
Against that backdrop, the Court examined the procedural history and the arbitration record. It was undisputed that the EOT defence was not raised in the pleadings and did not feature in the Terms of Reference or the parties’ List of Issues. The respondent had expressly pointed this out in its pleadings and submissions, and the appellants did not dispute that the EOT defence had not been advanced earlier. The appellants conceded that the EOT defence was raised for the first time in written closing submissions.
The Court of Appeal agreed with the High Court that this procedural posture was decisive. The EOT defence was not merely an alternative legal characterisation of the Estoppel Defence; it was factually and conceptually distinct. The respondent’s decision not to engage with the EOT defence in the context of the Estoppel Defence was therefore understandable and not something the respondent could be faulted for. Since the EOT defence was “completely new” in the arbitration’s closing stage, the respondent did not have a fair and reasonable opportunity to respond with evidence and submissions tailored to that issue.
In analysing the natural justice breach, the Court of Appeal endorsed the High Court’s “Primary NJ Breach” reasoning. The tribunal’s acceptance of the EOT defence effectively altered the case the respondent had to meet. The respondent had not been put on notice early enough to address the factual and legal requirements of GC 40 in a structured way, including through witness evidence and cross-examination. The Court’s approach reflects a core natural justice concern: fairness is not satisfied by post hoc opportunities to comment when the opposing party has not been given a meaningful chance to prepare its case.
The Court also upheld the “Secondary NJ Breach” finding. The tribunal had relied substantially on its professed experience to decide the EOT issue, but it did not explain what that experience entailed or what it encompassed. Crucially, the parties were not given an opportunity to address the tribunal on that basis. The Court treated this as prejudicial because it deprived the respondent of the chance to respond to the tribunal’s reasoning framework. This aspect of the decision underscores that arbitral tribunals must not rely on opaque or unexplained sources of expertise in a way that prevents a party from meaningfully engaging with the case.
On the jurisdictional point, the Court of Appeal agreed that the EOT defence was outside the scope of the parties’ submission to arbitration. The appellants had conceded that the EOT defence was not expressly mentioned in the request for arbitration, the answer to the request, the Terms of Reference, the pleadings, draft Lists of Issues, witness statements, opening submissions, or the oral hearing. The Court therefore treated the tribunal’s decision to grant an extension of time as an excess of jurisdiction because it went beyond what the parties had submitted for determination.
In reaching these conclusions, the Court of Appeal also addressed the appellants’ “hedging argument” (as described in the extract). While the details are truncated, the structure of the grounds indicates that the appellants attempted to characterise the tribunal’s decision as either procedurally permissible or within an acceptable range of arbitral discretion. The Court rejected this, holding that the tribunal’s acceptance of the EOT defence was not a legitimate exercise of discretion in managing submissions, but rather a fundamental departure from the agreed procedural scope and a breach of fairness.
Finally, the Court considered the “appropriate recourse”. The High Court had set aside the offending portion of the award relating to the EOT defence. The Court of Appeal agreed that remission (ie, sending the matter back to the tribunal) was not necessarily the only or best remedy, depending on the nature of the breach and the practical consequences. It also dealt with consequential orders, including how the liquidated damages calculation should be restored to the position before the improper extension of time was applied.
What Was the Outcome?
The Court of Appeal dismissed both appeals. It affirmed that the tribunal’s decision to allow the EOT defence and reduce liquidated damages by granting an extension of time was tainted by both excess of jurisdiction and breach of natural justice. Accordingly, the High Court’s partial setting aside of the award was upheld.
As a result, the practical effect was that the respondent’s entitlement to liquidated damages would revert to the position that excluded the tribunal’s improper extension of time. The Court also upheld the costs decision below (as reflected by CA 43 being dismissed), maintaining the High Court’s approach to costs in light of the outcome.
Why Does This Case Matter?
CAJ & Anor v CAI is significant for practitioners because it illustrates, in a concrete construction-arbitration setting, the boundary between permissible arbitral flexibility and impermissible procedural unfairness. While tribunals often have some latitude in how they frame issues and evaluate evidence, this case demonstrates that they cannot decide a new substantive issue late in the process—especially where the issue was not pleaded, not identified in the Terms of Reference, and not included in the List of Issues.
The decision also reinforces two natural justice principles that are frequently litigated in Singapore arbitration set-aside proceedings. First, parties must be given a fair and reasonable opportunity to respond to the case against them; fairness is assessed by reference to notice, preparation, and the ability to test evidence through the procedural tools available in arbitration. Second, tribunals must not rely on unexplained “experience” or other internal reasoning sources in a way that prevents parties from addressing the basis of the decision.
For lawyers, the case is a reminder to treat pleadings, procedural orders, and the Terms of Reference as more than formalities. If a party intends to rely on an extension of time clause (or any other substantive contractual mechanism that affects liability or quantum), it must be raised early enough to allow the opposing party to meet it. Conversely, if a tribunal accepts an unpleaded issue, the aggrieved party may have a strong basis to seek set aside on jurisdiction and natural justice grounds.
