Summary
Wan Sern Metal Industries Pte Ltd v Hua Tian Engineering Pte Ltd [2025] SGCA 5 concerns a challenge to an arbitral award arising from a “documents-only” SIAC arbitration conducted on an expedited basis. The Court of Appeal revisited the practical limits of natural justice in arbitration, emphasising that the right to be heard is a core facet of due process and must be meaningfully observed even where the parties have agreed to an accelerated procedure.
The dispute stemmed from a construction sub-contract and a related adjudication under Singapore’s Building and Construction Industry Security of Payment regime. After the adjudication, the parties proceeded to arbitration. The arbitral tribunal issued an award after a short timeline in which pleadings and witness evidence were exchanged in writing and no oral hearing was held. The appellant sought to set aside the award, arguing that the tribunal failed to appreciate and resolve material lack of clarity in the parties’ positions, thereby undermining procedural fairness.
The Court of Appeal held that the arbitrator could and should have recognised the lack of clarity and taken steps to resolve it. In doing so, the Court underscored that expedited “documents-only” arbitrations do not dilute the tribunal’s duty to ensure that the parties have a real and fair opportunity to present their case and respond to the case against them. The appeal succeeded, and the award was set aside.
What Were the Facts of This Case?
The appellant, Wan Sern Metal Industries Pte Ltd (“Wan Sern”), was a sub-contractor engaged in connection with a construction project known as Defu Industrial City (the “Project”). The main contractor was Lian Beng Construction (1988) Pte Ltd (“Lian Beng”). Wan Sern supplied a range of façade and glazing-related items, including aluminium windows and doors, glazing works, screens, louvres, skylights, canopies, and linkways.
Wan Sern engaged the respondent, Hua Tian Engineering Pte Ltd (“Hua Tian”), as its sub-contractor. Hua Tian’s role was to supply labour for the installation works. The parties entered into a sub-contract (the “Sub-Contract”) executed by Wan Sern on 4 May 2018 and by Hua Tian on 17 July 2018. Although the Sub-Contract itself did not contain an arbitration agreement, Wan Sern later relied on an arbitration clause in the main contract between Lian Beng and Wan Sern dated 28 November 2017, contending that it had been incorporated into the Sub-Contract.
Several years into performance, disputes arose. Wan Sern alleged that Hua Tian’s works were defective. Wan Sern sent notifications of defects to Hua Tian in June and July 2022 and then issued a notice of termination of the Sub-Contract on 15 July 2022. The termination became a focal point in the subsequent payment and dispute resolution processes.
Before the arbitration commenced, Hua Tian initiated an adjudication application under the Building and Construction Industry Security of Payment Act 2004 (2020 Rev Ed) (the “SOPA”) on 18 May 2022. The adjudication was based on Hua Tian’s payment claim dated 15 April 2022 for $846,159.87, and Wan Sern’s payment response dated 10 May 2022 for a negative sum of ($200,497.51). On 14 June 2022, the adjudicator allowed the majority of Hua Tian’s claims and rejected Wan Sern’s cross-claims. Wan Sern was ordered to pay $616,670.80 and bear adjudication costs (the “Adjudication Determination”).
What Were the Key Legal Issues?
The central legal issue was whether the arbitral award should be set aside for breach of due process—specifically, whether Hua Tian’s “documents-only” expedited arbitration deprived Wan Sern of a meaningful right to be heard. The Court of Appeal framed the inquiry around natural justice and the practical requirements of procedural fairness in arbitration.
A second issue concerned the tribunal’s handling of the parties’ positions. The Court noted that, due to the expedited nature of the arbitration, there was a lack of clarity as to the parties’ positions. The question was whether the arbitrator failed to appreciate that lack of clarity and, crucially, whether the arbitrator should have taken steps to resolve it so that the award could be reached on a fair and comprehensible basis.
Finally, the case required the Court to consider how arbitrators should balance party autonomy in agreeing to an accelerated procedure against the tribunal’s own duty to ensure procedural fairness sufficient to produce an enforceable award. This required the Court to revisit earlier guidance on expedited arbitration and the extent to which procedural expectations may be adjusted without crossing the line into unfairness.
How Did the Court Analyse the Issues?
The Court of Appeal began by situating the dispute within the broader framework of due process in arbitration. It emphasised that the right to be heard is an essential element of natural justice. In international arbitration, this right is reflected in Art 18 of the UNCITRAL Model Law on International Commercial Arbitration (the “Model Law”), which requires that each party be given a full opportunity to present its case and to respond to the case against it. The Court explained that curial intervention is warranted where a breach of due process prejudices a party and undermines the tribunal’s ability to deliver a just outcome on substantive rights.
The Court then addressed the question of how natural justice requirements operate in the context of expedited arbitration. It referred to its earlier decision in China Machine New Energy Corp v Jaguar Energy Guatemala LLC and another [2020] 1 SLR 695 (“China Machine”), where it had observed that expedited arbitration affects what parties can reasonably expect in terms of procedural accommodation. In China Machine, the Court had accepted that a tribunal could refuse a second extension of time in part because the parties had agreed to an expedited process, and granting further time would undermine that agreement. The Court in the present case used China Machine as a starting point but clarified that expedited procedure is not a blanket justification for procedural shortcuts that compromise fairness.
Turning to the arbitration itself, the Court highlighted the manner in which the proceedings unfolded. Within three months, the parties filed pleadings, witness statements, reply witness statements, written submissions, and reply written submissions. There was no oral hearing. Two months later, the arbitrator issued the award. While the parties chose this structure, the Court found that the expedited timeline resulted in a lack of clarity as to the parties’ positions, and that the arbitrator failed to resolve that lack of clarity.
The Court analysed the parties’ cases to show why the lack of clarity mattered. Before the arbitrator, Wan Sern’s position was not that Hua Tian had failed to carry out the pre-termination works. Instead, Wan Sern accepted that Hua Tian had performed those works, and its defence was that any amount due for pre-termination works was exceeded by “back charges” arising from alleged defects and related costs. When asked about this during the proceedings, Wan Sern’s counsel confirmed that this was the defence. In other words, Wan Sern’s case depended on a coherent accounting relationship between (i) what was due for pre-termination works and (ii) what Wan Sern claimed as back charges.
Wan Sern’s arbitral claims included back charges for third-party subcontractors it said it engaged to complete Hua Tian’s scope (the “Pan Sing and Toto Claims”), back charges for labour it said it provided due to Hua Tian’s alleged failure to deploy a competent safety supervisor (the “Safety Supervisor Fees Claim”), and back charges for labour it said it provided due to Hua Tian’s alleged failure to carry out various works on site (the “Labour Supply Claim”). Wan Sern also sought a declaration under s 21(1)(b) of the SOPA that no money was payable to Hua Tian pursuant to the Adjudication Determination (the “SOPA Declaration”).
Hua Tian’s counterclaims, by contrast, included damages for the full value of works done-to-date (the “Balance Work Counterclaim”), retention moneys said to have become payable because Wan Sern unlawfully terminated the Sub-Contract (the “Retention Sum Counterclaim”), and adjudication costs awarded in the Adjudication Determination (the “Adjudication Costs Counterclaim”).
The Court’s critique focused on the arbitrator’s approach to these issues. The arbitrator found that Wan Sern was not entitled to terminate the Sub-Contract because the evidence did not establish repudiatory breach by Hua Tian, and even if there were breaches, Wan Sern had not shown they were repudiatory. The arbitrator dismissed Wan Sern’s claims and allowed most of Hua Tian’s counterclaims. However, the Court of Appeal held that the arbitrator could and should have recognised the lack of clarity in the parties’ positions and taken steps to resolve it. The failure to do so meant that the award was not the product of a process that ensured each party had a fair opportunity to present and respond to the case.
In practical terms, the Court treated the “documents-only” format not as the problem per se, but as the context in which procedural fairness must be actively maintained. Where the record is unclear—particularly on matters that determine how claims and counterclaims interact—an arbitrator must ensure that the parties understand the issues the tribunal is deciding and have a fair chance to address them. The Court’s reasoning reflects a balancing exercise: party autonomy in agreeing to expedited procedure is respected, but the tribunal’s duty to preserve due process remains non-negotiable.
What Was the Outcome?
The Court of Appeal allowed Wan Sern’s appeal and set aside the arbitral award. The practical effect is that the award could not stand and could not be enforced on the basis of the defective arbitral process identified by the Court.
The decision also signals that, in future “documents-only” arbitrations, tribunals must be alert to material ambiguities or uncertainties in the parties’ positions and must take appropriate procedural steps to resolve them, even where the parties have agreed to an expedited timetable.
Why Does This Case Matter?
This case matters because it clarifies that expedited “documents-only” arbitration does not reduce the tribunal’s obligation to uphold due process. While China Machine recognises that expedited timelines may justify limiting certain procedural requests, Wan Sern Metal Industries demonstrates that the tribunal must still ensure that the parties’ positions are sufficiently clear and that the parties have a real opportunity to address the issues that will determine the outcome.
For practitioners, the decision is a reminder to treat procedural fairness as an active judicial/arbitral duty rather than a passive guarantee. Where the parties’ pleadings and submissions leave gaps or ambiguities—especially in complex construction accounting disputes involving termination, defects, and set-offs—counsel should consider requesting clarifications, targeted directions, or additional opportunities to address specific issues. Conversely, arbitrators should consider whether the record is clear enough to decide without risking a natural justice challenge.
From a precedent perspective, the Court of Appeal’s approach reinforces the enforceability-oriented rationale behind curial supervision of arbitration awards. Awards are not insulated from challenge simply because the parties agreed to speed. Instead, the decision emphasises that the right to be heard is assessed in substance: whether the process allowed each party to present its case and respond to the case against it in a meaningful way.
