Summary
In CBS v CBP ([2021] SGCA 4), the Court of Appeal considered the proper approach to an application to set aside an arbitral award on the ground of breach of natural justice. The dispute arose out of a maritime-related sale of coal under two backdated sale and purchase agreements, with arbitration conducted under the SCMA Rules. The award creditor, CBS (a Singapore bank), appealed against the High Court judge’s decision to set aside the arbitral award, primarily on the basis that the arbitral process had breached natural justice in relation to witness “gating” and the opportunity to present evidence.
The Court of Appeal’s analysis focused on whether the tribunal’s handling of witness testimony deprived the Buyer (CBP) of a fair opportunity to present its case, and—critically—whether any such breach affected the final award. The Court of Appeal also addressed the appropriate remedy, including whether partial setting aside and/or remission to the tribunal was warranted.
What Were the Facts of This Case?
CBS is a bank incorporated in Singapore. CBP is a company incorporated in India and engaged in steel manufacturing and power generation. The underlying commercial transaction involved the purchase of 50,000 metric tonnes (“MT”) of coal from an Australian seller. The coal was to be delivered in two tranches: 30,000 MT in December 2014 and 20,000 MT in January 2015. The parties’ arrangements were recorded in two separate sale and purchase agreements: the “First Agreement” for the first tranche and the “Second Agreement” for the second tranche.
Both agreements contained arbitration clauses providing for arbitration under the SCMA Rules. The agreements were backdated (the First Agreement to 24 November 2014 and the Second Agreement to 20 December 2014), but the relevant performance and payment events occurred in late 2014 and 2015. The first tranche delivery was not disputed. The dispute concerned the second shipment of 20,000 MT, shipped on 21 December 2014.
Before the coal shipment, the seller had entered into an accounts receivable purchase facility with CBS. Under that facility, the seller assigned its trade debts to the bank. In January 2015, the seller wrote to CBP (the Buyer) stating that all amounts due now and in the future in respect of invoices must be paid only to CBS. The Second Agreement also contained an assignment clause permitting the seller to assign receivables to banks and requiring the Buyer to execute documents reasonably necessary to give effect to or recognise the assignment.
Payment was effected through a bill of exchange drawn by the seller and sent to CBP. CBS sent a bill of exchange for US$1,480,400 by 22 June 2015. CBP’s bank sent a SWIFT message to CBS accepting the bill and stating that the accepted amount was US$1,480,400. CBP did not pay by the due date. CBS pursued payment through arbitration after repeated emails seeking payment. CBP’s position evolved: it initially admitted the debt and attributed delay to cash flow issues and market conditions, but later raised issues including alleged shortfall in delivery (only 15,000 MT rather than 20,000 MT) and a steep decline in coal prices, offering to pay a reduced price per MT.
What Were the Key Legal Issues?
The Court of Appeal identified the central legal issues as follows. First, whether the arbitral tribunal’s conduct amounted to a breach of natural justice. In particular, the case turned on the tribunal’s approach to witness testimony—often described in arbitration practice as “witness gating”—and whether CBP was denied a fair opportunity to present its case by being prevented from giving oral evidence at the hearing.
Second, the Court had to determine whether any breach of natural justice, if established, affected the final award. This is a crucial threshold in setting aside applications: not every procedural irregularity warrants intervention; the breach must be shown to have had a material impact on the outcome.
Third, the Court needed to consider the appropriate remedy. If the award was to be disturbed, the Court had to decide whether the correct response was to set aside the award fully, partially, or to remit the matter to the tribunal for reconsideration in a manner consistent with the requirements of fairness.
How Did the Court Analyse the Issues?
The Court of Appeal approached the natural justice question by examining the arbitration timeline and the tribunal’s procedural decisions. After a jurisdictional objection, the tribunal issued a Partial Award on 6 December 2017, holding that the assignment of receivables included assignment of the entire Second Agreement, including the arbitration clause. That jurisdictional finding meant the tribunal had authority to determine the merits dispute between CBS and CBP.
Following the Partial Award, CBP was directed to file its defence by 8 January 2018 but failed to do so. The tribunal indicated that it would proceed on the basis that CBP had elected not to file a defence and/or counterclaim unless advised otherwise. CBP responded by challenging the Partial Award in the Indian courts and requested that the tribunal await the outcome. Shortly before the final oral hearing, CBP then informed the tribunal that it intended to contest the claim on the merits, while maintaining its protest as to jurisdiction, and sought time to file its defence.
The tribunal granted CBP time to file its defence and counterclaim and directed the parties to review and agree on whether an oral hearing was necessary. The tribunal’s email indicated that if the parties could not agree that the decision should be based on documents only, the tribunal would schedule a hearing pursuant to the SCMA Rules. This procedural step mattered because it set up the later dispute: whether the hearing would be documents-only or whether CBP’s witnesses would be permitted to give oral testimony.
CBP’s “reply on merits” was filed with a list of seven witnesses, six of whom were persons CBP claimed were present at a December 2015 meeting where CBP alleged an oral settlement agreement was reached to revise the coal price for the entire 50,000 MT from US$74 per MT to US$61 per MT. CBP also counterclaimed for the cost of procuring the alleged shortfall from the open market. CBS, in response, indicated it did not intend to call witnesses and took the position that the dispute turned primarily on contractual interpretation and that CBP had not adequately explained why it needed the seven witnesses. CBS therefore urged the tribunal to proceed on a documents-only basis, or alternatively to hold a hearing for oral submissions only, without oral evidence from witnesses.
The Court of Appeal’s analysis of natural justice focused on whether the tribunal’s “gating” decision prevented CBP from presenting evidence that was relevant and necessary to its case. Natural justice in arbitration is concerned with fairness: the parties must have a reasonable opportunity to present their case, including the opportunity to adduce evidence in a manner consistent with the tribunal’s procedural directions and the parties’ reasonable expectations. The Court examined whether CBP had been given a fair chance to explain the relevance of its witnesses and whether the tribunal’s decision to limit or exclude oral testimony was justified in the circumstances.
Importantly, the Court did not treat “breach” as an automatic consequence of limiting witness testimony. The Court recognised that tribunals have case management powers, including decisions about whether oral evidence is necessary. However, those powers must be exercised in a way that preserves the essential fairness of the process. The Court therefore assessed whether the tribunal’s approach crossed the line from permissible procedural management into a denial of a party’s opportunity to present its case.
Having considered whether a breach occurred, the Court then addressed the second threshold: whether the breach affected the final award. The Court’s reasoning indicates that even if a procedural unfairness is identified, setting aside requires a showing of materiality. The Court examined the role that the gated witnesses would have played in resolving the key factual dispute—particularly the alleged December 2015 oral agreement to revise the price. If the tribunal’s decision effectively prevented CBP from substantiating that alleged agreement, and if that agreement was central to the merits, then the breach would likely have affected the award. Conversely, if the tribunal’s decision relied on matters that did not turn on witness testimony, or if CBP’s evidence would not have changed the outcome, then the breach might not meet the materiality requirement.
Finally, the Court considered the remedy. The Court of Appeal agreed with the general principle that where a breach of natural justice is established and has affected the award, the appropriate remedy may be partial setting aside and/or remission rather than a full re-run of the entire arbitration. Remission is particularly apt where the defect is confined to a specific procedural step (for example, the handling of witness testimony) and the tribunal can be directed to address that defect while preserving unaffected parts of the award.
What Was the Outcome?
The Court of Appeal upheld the High Court’s approach to setting aside, concluding that the arbitral process had breached natural justice in a manner that affected the final award. The practical effect was that the award could not stand in its existing form.
Rather than ordering a complete restart, the Court’s remedial direction reflected the targeted nature of the procedural defect. The matter was remitted to address the specific fairness issue concerning witness testimony, ensuring that CBP would have a fair opportunity to present the evidence necessary to its case.
Why Does This Case Matter?
CBS v CBP is significant for arbitration practitioners because it clarifies how far a tribunal may go in managing hearings and limiting witness testimony without breaching natural justice. While tribunals are entitled to control procedure and avoid unnecessary oral evidence, the Court of Appeal emphasised that fairness requires a reasonable opportunity to present the case, particularly where witness evidence is linked to a live and material factual dispute.
The decision also reinforces the materiality requirement in setting aside applications. Parties seeking to set aside an award must do more than point to a procedural irregularity; they must show that the breach affected the award. This is a practical lesson for both applicants and respondents: applicants should build a clear evidential narrative connecting the alleged unfairness to the tribunal’s reasoning, while respondents should be prepared to argue that any procedural limitation did not prejudice the outcome.
From a remedies perspective, the case illustrates the Court’s preference for proportionate relief. Where the defect is confined—such as the handling of witness testimony—the Court may order partial setting aside and remission, rather than requiring a full re-hearing. This approach supports arbitration efficiency while maintaining the integrity of the arbitral process.
