Summary
This case concerns a statutory adjudication under Singapore’s Building and Construction Industry Security of Payments framework. WCS Engineering Construction Pte Ltd (“WCS”), the main contractor, applied to set aside an adjudication determination made in favour of Glaziers Engineering Pte Ltd (“Glaziers”), the subcontractor. The adjudicator had allowed Glaziers’ claim and rejected WCS’s deductions/backcharges arising from incidents where sliding glass shower doors shattered in multiple units at the Hillford residential development.
The High Court (Vinodh Coomaraswamy J) held that the adjudicator breached the principles of natural justice. The adjudicator reached a holding on the applicable standard of proof for WCS’s claimed deductions—namely that WCS had to satisfy the adjudicator “beyond reasonable doubt” that its deductions were valid—without soliciting submissions or giving WCS an opportunity to address that issue. The court treated this as more than a mere error of law: it was a procedural unfairness because the evidential issue was not a live issue in the adjudication and was decided without hearing the parties.
Accordingly, the court set aside the adjudication determination. The decision underscores that, even within the fast and streamlined adjudication process, adjudicators must comply with natural justice, particularly where they decide an issue that materially affects the outcome and where the parties have not been given a fair chance to respond.
What Were the Facts of This Case?
WCS was the main contractor for a large residential development known as “The Hillford”, comprising 281 flats in six blocks. Construction began in March 2014 and concluded around October 2016, after which a temporary occupation permit was issued and the flats were handed over to subsidiary proprietors. A distinctive feature of the development was its design for elderly residents, including an elderly-care centre and elderly-related facilities.
In January 2015, WCS appointed Glaziers as the aluminium, stainless steel and glazing subcontractor. The subcontract value was a little over S$900,000. Glaziers’ scope included fabricating, supplying and installing semi-frameless shower screens in all 321 bathrooms. Work commenced in February 2015 and was completed in October 2016.
After completion, a serious defect manifested: between October 2016 and January 2017, sliding glass doors in at least nine shower frames across eight units shattered while in use. In many instances, personal injuries resulted, some of which were serious. The developer, the developer’s architect, and WCS and Glaziers held meetings to identify the root cause and implement a solution. The developer asked its architect to gather facts and documents to determine why the doors were shattering.
WCS’s initial position was that the shattering was caused by defective materials or defective workmanship by Glaziers. Glaziers responded with alternative explanations: (i) users may have applied too much force when sliding the doors, causing the leading vertical edge to strike the wall; (ii) the glass may have been prone to spontaneous shattering due to nickel sulphide inclusions, an inherent characteristic of tempered glass rather than a defect; and (iii) design and space constraints in the shower area may have caused the glass doors to strike the wall when opened. On 27 December 2016, WCS (through solicitors) put Glaziers on notice that WCS would seek damages and an indemnity for losses arising from what WCS characterised as negligent installation. Glaziers denied defects in materials or installation in a letter dated 11 January 2017, and it also pointed out that only sliding panels shattered, not identical fixed panels. Glaziers further asserted that if the cause was contact with the wall when opened, it would contest any backcharge and consider remedial work to be a variation at WCS’s cost.
By 13 February 2017, the developer’s architect informed WCS of two root causes: first, some shower frames had been installed with a buffer of less than 30mm between the vertical edge of the glass door and the wall, increasing the likelihood of edge striking; second, the rollers in the aluminium tracks allowed the doors to slide too freely, enabling excessive speed and momentum in normal usage. To address these root causes, the architect required three remedial steps for all 321 shower screens: rubber studs on tracks to slow the doors, clear plastic edge seals to protect the leading edge, and lamination with safety film so that shards would be held in place even if the door struck and shattered.
Glaziers agreed to replace, at its own cost and without admission of liability, all doors that had shattered. However, it refused to carry out the additional remedial steps unless WCS accepted that the work would be treated as a variation to the subcontract. As a result, in January and February 2017, the developer and WCS arranged for the further remedial work themselves, and it appeared that WCS ultimately bore the cost. WCS also reimbursed medical expenses of residents who suffered personal injuries.
Against this background, Glaziers served a payment claim on 22 February 2017 under the statutory regime. The claim covered all work remaining unpaid, and it effectively functioned as Glaziers’ version of the final account. Glaziers claimed a total of S$204,279.96 (including GST), including S$109,910.40 for supplying and installing 321 glass shower screens. WCS served a payment response on 7 March 2017, seeking to backcharge S$78,659.96 for “costing incurred for the shattering of shower screen”, including medical claims reimbursed, attendance costs, and costs of remedial work. WCS also made other deductions and adjustments, resulting in WCS’s version of the final account showing that Glaziers owed WCS.
What Were the Key Legal Issues?
The central legal issue was procedural: whether the adjudicator complied with the obligation to observe natural justice under s 16(3)(c) of the Building and Construction Industry Security of Payments Act. Specifically, the court focused on whether the adjudicator breached natural justice by deciding that WCS had to prove the validity of its deductions “beyond reasonable doubt” without giving WCS an opportunity to make submissions on that standard of proof.
A related issue was conceptual and practical: whether the adjudicator’s approach amounted to an error of law only, or whether it crossed the threshold into a natural justice breach. The court framed the question in terms of whether a wrong holding on an issue of law, reached without hearing submissions on that issue, is merely an error or a breach of natural justice.
In addition, the case implicitly raised the question of what constitutes a “live issue” in adjudication proceedings. The court examined whether the standard of proof was raised by the parties or became a contested matter during the adjudication, or whether it was introduced by the adjudicator as a decisive evidential requirement without notice.
How Did the Court Analyse the Issues?
The High Court began by emphasising the statutory requirement that adjudicators must comply with natural justice when determining an adjudication application. While adjudication is designed to be rapid and to avoid full-scale litigation, the court made clear that procedural fairness cannot be sacrificed. The adjudicator’s role is not merely to decide; it is to decide fairly, including by ensuring that parties have a meaningful opportunity to address the issues that will determine the outcome.
The court then analysed the adjudicator’s determination. The adjudicator had held that WCS had to satisfy the adjudicator beyond reasonable doubt that the deductions it claimed were valid deductions. Critically, the court found that this evidential issue—what standard of proof applied to the validity of deductions—was not a live issue in the adjudication. There was no indication that the parties had argued about the standard of proof, and the adjudicator did not solicit submissions from either party on that point.
In other words, the adjudicator introduced a decisive legal/evidential threshold and applied it against WCS without giving WCS a chance to respond. The court treated this as a natural justice problem rather than a mere substantive mistake. The reasoning was that natural justice requires notice and an opportunity to be heard on the issues that materially affect the decision. Where an adjudicator decides an issue that the parties have not been invited to address, the parties are deprived of the chance to tailor their submissions and evidence to the adjudicator’s approach.
The court also addressed the distinction between an error of law and a breach of natural justice. Even if the adjudicator’s conclusion on the standard of proof were characterised as an error, the absence of a hearing on that issue meant that the adjudication process was procedurally unfair. The court’s framing of the issue—whether the adjudicator’s wrong holding was simply an error or a natural justice breach—was answered by reference to the procedural context: the parties were not heard on the standard of proof, and the issue was not live.
Although the judgment extract provided does not include the full discussion of the adjudication’s evidential and substantive merits, the court’s decision turned on the procedural defect. The court considered the “unusual features” of the case and concluded that the adjudicator’s approach was inconsistent with the statutory natural justice requirement in s 16(3)(c). The practical effect was that the adjudication determination could not stand.
Notably, the court’s approach reflects a broader principle in construction adjudication: adjudication is not a substitute for trial, but it is still a decision-making process that must respect procedural fairness. Where adjudicators decide issues that were not raised and not canvassed, they must ensure that parties are given an opportunity to respond; otherwise, the determination risks being set aside.
What Was the Outcome?
The High Court set aside the adjudication determination. The court held that the adjudicator breached natural justice by deciding that WCS had to satisfy the adjudicator beyond reasonable doubt as to the validity of its deductions, without soliciting or receiving submissions on the standard of proof and without the issue being live in the adjudication.
The defendant, Glaziers, appealed against the court’s decision, but the High Court’s grounds established that the adjudication could not be upheld due to the procedural unfairness identified.
Why Does This Case Matter?
This decision is significant for practitioners because it clarifies the boundary between substantive adjudication errors and procedural unfairness. In the statutory adjudication regime, parties often focus on the merits of claims and deductions, but this case demonstrates that adjudicators’ procedural handling of evidential/legal thresholds can be decisive. If an adjudicator introduces a new decisive issue—such as a particular standard of proof—without giving parties a chance to address it, the determination may be vulnerable to being set aside.
For contractors and subcontractors, the case highlights the importance of ensuring that adjudication submissions are responsive to the issues that are actually contested. However, it also imposes a corresponding duty on adjudicators to avoid ambush decisions. Practically, parties may consider requesting clarification or submissions on any evidential standards that appear to be emerging as decisive, especially where the adjudicator signals a particular approach.
From a precedent perspective, the case reinforces that natural justice under s 16(3)(c) is not a formality. Even in a streamlined adjudication, the parties must be heard on the issues that determine the outcome. Lawyers advising clients in adjudication disputes should therefore pay close attention not only to what the adjudicator decides, but also to how the adjudicator arrived at the decision and whether the parties were given a fair opportunity to address the relevant issues.
