Summary
The decision in Soon Li Heng Civil Engineering Pte Ltd v Samsung C&T Corporation & Anor [2019] SGHC 267 represents a significant judicial intervention in the realm of performance bonds, specifically addressing the intersection between the "temporary finality" of the Building and Construction Industry Security of Payment Act ("SOPA") and the equitable doctrine of unconscionability. The High Court was tasked with determining whether a main contractor’s call on a performance bond ("PB") was unconscionable when that call appeared to be a strategic attempt to circumvent an adverse adjudication determination.
The dispute arose from a multi-million dollar subcontract for excavation and disposal works for the Thomson-East Coast Line project. Following a successful adjudication by the subcontractor (the Plaintiff), the main contractor (the First Defendant) paid the adjudicated sum but subsequently issued a call on the PB for S$826,713.53. The First Defendant justified the call by alleging that the Plaintiff had engaged in "persistent dishonest conduct" and "fraudulent over-claims," based on a discrepancy between the quantities claimed by the Plaintiff and the quantities recorded by the Land Transport Authority ("LTA").
The Court’s analysis centered on whether the First Defendant’s call was motivated by a bona fide belief in its entitlement or by an improper purpose. Ang Cheng Hock J held that the call was indeed unconscionable. The Court found that the First Defendant was attempting to use the PB mechanism to "claw back" sums it had been ordered to pay in the adjudication by re-litigating measurement issues that had already been decided by the adjudicator. This conduct was found to be so lacking in bona fides that it warranted the granting of an injunction to restrain the call.
This judgment clarifies that while the threshold for unconscionability remains high, the Court will not permit a beneficiary to use a performance bond as a tool to undermine the statutory adjudication regime. It reinforces the principle that a call on a bond must be made for the purpose of securing the performance of the contract, rather than as a tactical maneuver to bypass the "pay now, argue later" philosophy of the SOPA.

What Were the Facts of This Case?
The First Defendant, Samsung C&T Corporation, was the main contractor for the construction of the Marine Parade Station and Tunnels for the Thomson-East Coast Line (Project T221). On 22 April 2016, it engaged the Plaintiff, Soon Li Heng Civil Engineering Pte Ltd, as a subcontractor to perform excavation and disposal works. The Subcontract was a "Re-Measurement Sub-Contract" with an initial value of approximately S$16.5 million. As a condition of the Subcontract, the Plaintiff was required to provide a performance bond. This was fulfilled by the Second Defendant, United Overseas Bank Limited, which issued a PB (No. G0161601323SEC) in the sum of S$826,713.53, representing 5% of the Subcontract value.
The operational core of the dispute involved the disposal of three distinct categories of excavated material: (a) soil; (b) hardcore material; and (c) ground improvement and mixed material. The disposal routes were strictly defined. Soil was to be sent directly to the LTA’s dumping ground at the Marina East Staging Ground ("MESG"). Hardcore material, which MESG would not accept, was to be disposed of at the Plaintiff’s own dumping ground. Ground improvement and mixed material were to be sent to the Plaintiff’s staging ground (referred to as "TOL") for treatment and crushing before being sent to MESG.
The payment mechanism under the Subcontract relied on the measurement of these materials. Specifically, for soil and mixed material sent to MESG, the quantities were tracked via LTA "trip tickets." However, for material sent to the Plaintiff’s TOL or its own dumping ground, the Subcontract provided for measurement based on the "theoretical volume" of the excavation or the number of lorry loads, using specific conversion factors. The Plaintiff claimed payment based on these contractual measurement methods.
In August 2018, the Plaintiff served PC 20. The First Defendant disputed the quantities, leading to adjudication (SOP 372/2018). The adjudicator, in 1AD, largely accepted the Plaintiff’s measurement methodology, particularly the use of a conversion factor for mixed material processed at the TOL. The adjudicator determined that the First Defendant owed the Plaintiff S$2,473,295.20. Although the First Defendant paid this sum on 26 December 2018, it did so under protest, having already begun a campaign to challenge the Plaintiff’s claims.
In December 2018, the First Defendant began alleging that the Plaintiff had engaged in a "fraudulent over-claim." This allegation was based on a comparison between the total quantity of material the Plaintiff claimed to have excavated and the total quantity of material the LTA recorded as having been received at MESG. The First Defendant asserted that there was a massive discrepancy of over 100,000 m3. To bridge this gap, the First Defendant applied its own assumptions: a density of 2000 kg/m3 for the material and a capacity of 8 m3 per lorry. Based on these calculations, the First Defendant concluded that the Plaintiff had over-claimed S$2,057,944.79 and called the PB on 8 January 2019, citing the Plaintiff's alleged dishonesty as the basis for the call.
What Were the Key Legal Issues?
The primary legal issue was whether the First Defendant’s call on the PB was unconscionable, thereby justifying an injunction to restrain the Second Defendant from making payment and the First Defendant from receiving the proceeds. This required the Court to navigate the following sub-issues:
- The Threshold for Unconscionability: Whether the Plaintiff had established a "strong prima facie case" of unconscionability, as required by Singapore law, which is a higher standard than the "serious question to be tried" standard used for other interim injunctions.
- Improper Purpose: Whether the First Defendant’s call was motivated by a genuine desire to protect itself against breaches of contract or whether it was an attempt to circumvent the 1AD adjudication determination and "claw back" the adjudicated sum.
- The Validity of the Fraud Allegations: Whether the First Defendant’s allegations of "dishonest conduct" and "fraudulent over-claims" were supported by the evidence or were merely a repackaging of a measurement dispute that had already been adjudicated.
- Interaction with SOPA: To what extent the "temporary finality" of an adjudication determination under s 21 of the Building and Construction Industry Security of Payment Act (Cap 30B, 2006 Rev Ed) informs the Court’s assessment of unconscionability in a bond call.
How Did the Court Analyse the Issues?
The Court began by reaffirming the established legal framework for performance bonds in Singapore. Unlike the English position, which generally only recognizes fraud as a ground to restrain a bond call, Singapore law recognizes "unconscionability" as a distinct and independent ground. The Court cited BS Mount Sophia Pte Ltd v Join-Aim Pte Ltd [2012] 3 SLR 352, noting that unconscionability involves conduct so lacking in bona fides that an injunction is warranted. The standard of proof is a "strong prima facie case" (at [35]).
In analyzing the facts, the Court scrutinized the First Defendant’s justification for the call. The First Defendant’s primary argument was that the Plaintiff had over-claimed by comparing the Plaintiff's claims with LTA's MESG records. The Court found this comparison fundamentally flawed for several reasons:
"the call on the PB was motivated by the improper purpose of effectively overturning parts of the adjudicator’s determination in 1AD, and this undermines the temporary finality of 1AD." (at [103])
First, the Court noted that the Subcontract specifically allowed for material to be disposed of at the Plaintiff’s TOL and its own dumping ground. Naturally, material sent to these locations would never appear in the LTA’s MESG records. Therefore, a discrepancy between the Plaintiff's total excavation claims and the LTA's MESG records was not only expected but inevitable. The First Defendant’s failure to account for the material sent to the TOL and other dumping grounds in its "fraud" calculation suggested a lack of bona fides.
Second, the Court examined the First Defendant’s use of conversion factors. The First Defendant had assumed a density of 2000 kg/m3 and a lorry capacity of 8 m3 to calculate the volume of material. However, the adjudicator in 1AD had already considered and rejected similar arguments, instead accepting the Plaintiff’s methodology based on the Subcontract’s terms. The Court found that the First Defendant was essentially trying to re-litigate the measurement dispute under the guise of a "fraud" allegation to justify calling the PB.
The Court also looked at the timing of the call. The First Defendant paid the 1AD sum on 26 December 2018 and called the PB just two weeks later on 8 January 2019. The Court observed that the First Defendant’s internal correspondence and payment responses showed a clear intent to "recover" the 1AD sum. For instance, in Payment Response No. 24, the First Defendant certified a negative amount that almost exactly offset the 1AD award. The Court concluded that the call was not a genuine attempt to seek security for performance but a tactical move to neutralize the effect of the adjudication.
The Court distinguished this case from others where a call was allowed despite a pending dispute. Here, the First Defendant’s conduct went beyond a mere disagreement over figures. By labeling a measurement dispute as "fraud" without a sound factual basis and using it to call a bond immediately after losing an adjudication on those very measurement issues, the First Defendant crossed the line into unconscionability. The Court emphasized that the PB is intended to provide security for the performance of the works, not to serve as a "backdoor" for a party to recover sums paid under the SOPA regime while waiting for a final resolution by arbitration or litigation.
Finally, the Court addressed the First Defendant's reliance on W Y Steel Construction Pte Ltd v Osko Pte Ltd [2013] 3 SLR 380. The First Defendant argued that because the SOPA determination was only "temporarily final," it should be allowed to call the bond to protect its position. The Court rejected this, holding that while the determination is temporary, s 21 of the SOPA requires the parties to give effect to it until the dispute is finally resolved. Calling a bond to effectively "stay" the payment of an adjudicated sum is inconsistent with the statutory purpose of the SOPA.
What Was the Outcome?
The High Court ruled in favor of the Plaintiff, finding that the call on the performance bond was unconscionable. The Court granted the following orders as requested in Originating Summons No. 439 of 2019:
- An injunction restraining the First Defendant from receiving any payment from the Second Defendant under the PB.
- An injunction restraining the Second Defendant from making any payment to the First Defendant under the PB.
- An order that the First Defendant withdraw its demand for payment made on 8 January 2019.
The operative conclusion of the Court was stated as follows:
"I grant prayers (1) to (3) of Originating Summons 439 of 2019." (at [104])
Regarding costs, the Court did not make an immediate award but stated:
"I will hear the parties separately on the question of costs." (at [105])
The effect of the judgment was to maintain the status quo regarding the cash flow established by the adjudication determination. The First Defendant was prevented from using the PB to recoup the S$2,473,295.20 it had paid to the Plaintiff. The underlying measurement and "fraud" disputes were left to be resolved in the eventual arbitration between the parties, as provided for in the Subcontract. The judgment effectively protected the Plaintiff's liquidity, which is the primary objective of the SOPA regime, by preventing the First Defendant from using the PB as a self-help remedy to bypass the adjudicator's decision.
Why Does This Case Matter?
This case is a landmark for construction practitioners in Singapore because it defines the limits of a beneficiary's power to call on a performance bond in the shadow of an adverse SOPA adjudication. It provides a clear roadmap for when a call will be deemed unconscionable, particularly in the context of "claw-back" attempts.
First, it reinforces the "temporary finality" of adjudication determinations. While main contractors often feel aggrieved by adjudicators' decisions, this case makes it clear that they cannot use performance bonds as a strategic tool to undo the financial impact of those decisions. The Court’s finding that the call was motivated by an "improper purpose"—specifically to overturn the 1AD determination—sets a high bar for bona fides. Practitioners must ensure that any call on a bond is supported by a genuine, independent basis for a claim that has not already been rejected in adjudication, or at least that the call is not a transparent attempt to neutralize an adjudication award.
Second, the judgment provides a cautionary tale regarding allegations of fraud. The First Defendant’s attempt to characterize a measurement discrepancy as "dishonest conduct" backfired because the Court looked past the labels to the underlying facts. The Court’s detailed analysis of the disposal routes (MESG vs TOL) and the conversion factors shows that judges will scrutinize the technical merits of a "fraud" allegation when it is used to justify a bond call. Simply shouting "fraud" is not enough to avoid a finding of unconscionability if the "fraud" is merely a repackaged contractual dispute.
Third, the case clarifies the "strong prima facie case" standard. The Plaintiff succeeded because it was able to show, through the timeline and the First Defendant’s own correspondence, that the call was tactically timed and substantively weak. This demonstrates that while the standard is high, it is not insurmountable if the applicant can provide a cohesive narrative of improper motive.
Finally, for the broader Singapore legal landscape, the case affirms the Court's willingness to protect the integrity of the SOPA regime. By preventing the PB from being used to circumvent s 21 of the SOPA, the Court ensured that the "pay now, argue later" principle is not rendered toothless by the "pay now, call bond later" tactics of main contractors. This provides much-needed security for subcontractors who rely on the SOPA for cash flow in large-scale infrastructure projects.
Practice Pointers
- For Beneficiaries (Main Contractors): Before calling a performance bond following an adverse adjudication, ensure the grounds for the call are distinct from the issues decided by the adjudicator. If the call is based on the same measurement or valuation disputes, it is highly likely to be viewed as an unconscionable "claw-back" attempt.
- Documenting Motive: Be wary of internal and external correspondence that suggests a bond call is being made to "recover" or "offset" an adjudicated sum. Such evidence was pivotal in this case to establish an improper purpose.
- Technical Justification: If alleging fraud or gross over-claiming as a basis for a call, ensure the technical assumptions (e.g., conversion factors, lorry capacities) are robust and consistent with the contract terms. Using LTA data to "prove" fraud when the contract allows for non-LTA disposal routes is a high-risk strategy.
- For Applicants (Subcontractors): When seeking to restrain a call, focus on the timeline. A call made shortly after an adjudication award, especially if it matches the awarded sum, is strong evidence of unconscionability.
- SOPA Interaction: Leverage the "temporary finality" of s 21 SOPA. Argue that a bond call intended to bypass an adjudication determination undermines the statutory scheme, as this resonated strongly with the Court in Soon Li Heng.
- Standard of Proof: Remember that you must establish a "strong prima facie case" of unconscionability. This requires more than just showing a "serious question to be tried"; it requires evidence of a lack of bona fides.
Subsequent Treatment
The ratio in Soon Li Heng Civil Engineering Pte Ltd v Samsung C&T Corporation & Anor has been recognized as a key authority on the "improper purpose" aspect of unconscionability. It is frequently cited in construction disputes where a party attempts to use a performance bond to circumvent the "temporary finality" of an adjudication determination under the SOPA regime. The case reinforces the principle that the court will protect the integrity of the statutory adjudication process from tactical maneuvers involving security instruments.
