CBS v CBP: exclusion of witness evidence and setting aside

Case and procedure

On 20 January 2021 the Singapore Court of Appeal decided CBS v CBP, [2021] SGCA 4, Civil Appeal No 30 of 2020. The bank CBS appealed against an order setting aside the award in its favour. The arbitration concerned payment for coal and was conducted under the 2015 SCMA Rules.

The excluded evidence

The buyer alleged that a later meeting had produced an oral agreement reducing the price and sought testimony from persons present. The arbitrator required witness statements to decide whether the evidence had sufficient substantive value and whether any witness hearing should take place. Ultimately, a hearing was held only for oral submissions and all the buyer’s witness evidence was excluded.

The buyer had missed deadlines and behaved inconsistently. Nevertheless, the Court examined the relationship between the arbitrator’s specific procedural decision and the opportunity under the agreed rules to present material evidence, rather than deciding the application on an abstract assessment of the party’s cooperativeness.

The test and reasoning

Paragraphs 75–79 distinguish a legitimate request for witness statements to organise a hearing from an improper condition determining whether a witness hearing would occur at all in these circumstances. Broad case-management powers did not remove the safeguards supplied by the agreed rules and natural justice.

In paragraphs 80–85 the Court connected the breach with the award and prejudice to the buyer. The proposed witnesses could address the central defence concerning a changed price; their potential effect was real rather than fanciful. The decision therefore did not rest on a merely technical error or judicial disagreement with the tribunal’s assessment of evidence it had actually received.

Disposition and boundaries

Paragraphs 90 and 112–114 affirm setting aside of the whole award and dismiss the bank’s appeal. The Court declined to confine the annulment to a supposed price difference or remit the already annulled award on a request first made in the appeal. Paragraph 113 leaves an alternative jurisdictional challenge undecided because it was unnecessary to the outcome.

The case establishes neither an unconditional right to call unlimited witnesses nor a prohibition on reasonable evidentiary deadlines and limits. The applicable rules, the excluded material, the party’s opportunities and the substantial effect of the breach remain essential.
