Summary
Sin Herh Construction Pte Ltd v Hyundai Engineering & Construction Co Ltd & Anor concerned an application to restrain the call on a performance bond and to obtain an Erinford order. The Plaintiff, Sin Herh Construction Pte Ltd, sought to stop the 1st Defendant, Hyundai Engineering & Construction Co Ltd, from making payment under a performance bond issued by the 2nd Defendant, China Taiping Insurance (Singapore) Pte Ltd. The Plaintiff’s central argument was that the 1st Defendant’s demand was unconscionable.
The High Court (Kan Ting Chiu SJ) refused the interim injunction and refused to grant an Erinford order. The court held that the Plaintiff failed to establish the kind of strong case required to override the general policy that performance bonds should be honoured promptly upon demand. In particular, the court was not persuaded that there was a binding understanding that the bond would not be called, and it was also not satisfied that the Plaintiff’s complaints about back-charges demonstrated unconscionability at the threshold required for injunctive relief.
What Were the Facts of This Case?
The underlying dispute arose from a construction subcontract. The Plaintiff and the 1st Defendant were parties to an agreement dated 8 April 2013 under which the Plaintiff was engaged to carry out reinforced concrete works for a project described as “Punggol Central/Punggol Walk – Waterway Point 2 Watertown”. As security for due performance, the Plaintiff provided a performance bond. The bond was issued by the 2nd Defendant in the sum of S$404,035.01. Its initial expiry was 9 July 2015, and it was later extended to 9 October 2015.
The performance bond permitted demand to be made at any time up to 90 days after expiry. Accordingly, the demand window extended to 7 January 2016. On 5 January 2016, the 1st Defendant made a demand on the bond. The Plaintiff then applied for an interim injunction on 8 January 2016, seeking, among other relief, to restrain the 1st Defendant from receiving payment and to restrain the 2nd Defendant from making payment.
The Plaintiff’s case was that the 1st Defendant’s demand was unconscionable. Two broad factual themes were advanced. First, the Plaintiff alleged that there was an understanding between the parties that the bond would not be called pending finalisation of the final accounts. Second, the Plaintiff alleged that the 1st Defendant imposed back-charges that were either not contractually entitled or grossly inflated, and that these back-charges formed the basis for the bond demand.
As to the alleged understanding, it was common ground that the Plaintiff did not carry out the contracted works in compliance with the agreement. The Plaintiff missed deadlines and withdrew a substantial number of workers from the worksite. These issues led to concern on the part of the 1st Defendant and ultimately to two meetings between senior officials on 29 and 30 June 2015. The meetings resulted in a written Supplementary Sub-Contract Agreement dated 30 June 2015.
What Were the Key Legal Issues?
The primary legal issue was whether the Plaintiff had met the high threshold for an Erinford injunction (often referred to as an “Erinford order”) to restrain a call on a performance bond. Performance bonds are generally intended to provide quick and reliable security. The court therefore starts from a strong policy position that a bond should be honoured according to its terms upon demand, and that injunctions restraining payment are exceptional.
Within that overarching issue, the court had to consider whether the Plaintiff’s allegations—(i) an alleged understanding not to call the bond and (ii) alleged unconscionable back-charges—were capable of establishing “unconscionability” in the relevant sense. The question was not whether the Plaintiff might ultimately succeed in its underlying contractual claims, but whether the demand itself was so tainted that the court should intervene at the interim stage.
A further issue was evidential and contractual: whether the alleged “understanding” was sufficiently clear, binding, and reflected in the written Supplementary Sub-Contract Agreement. The court also had to assess whether the Plaintiff’s challenge to the quantum and basis of back-charges could amount to unconscionability rather than merely a dispute about entitlement or calculation.
How Did the Court Analyse the Issues?
The court began by framing the dispute as an application to restrain the holder of a performance bond from making a call. The court recognised that the performance bond mechanism is designed to operate independently of the underlying disputes. Accordingly, the Plaintiff needed to show more than a mere dispute over contractual performance or accounting. The court required a strong case that the demand was unconscionable, and that the circumstances justified an exceptional interference with the bond’s payment function.
On the alleged understanding, the court examined the Supplementary Sub-Contract Agreement and the parties’ affidavits. The Plaintiff’s director, Pan Zhengwen (“Pan”), deposed that there was an understanding reached pending finalisation of the final accounts that there would be no call on the performance bond. In a second affidavit, Pan stated that the understanding was reached between himself and the 1st Defendant’s Mr J.H. Park, and he suggested that the understanding was implicit in the arrangement because it would have been unreasonable to discuss final accounts while allowing the 1st Defendant to call on the bond.
The 1st Defendant, through its project manager Park Ji Hong (“Park”), gave a different account of the meetings. Park deposed that the meetings were primarily to address the Plaintiff’s delay and threats to stop work, as well as the Plaintiff’s request for more payment. Park emphasised that the Supplementary Sub-Contract Agreement embodied agreements on payment schedule, construction program, and manpower mobilisation, and that the main purpose was to give the Plaintiff more time to carry out the works. Park also highlighted that the Plaintiff had never written to record the alleged understanding or object that it was not reflected in the Supplementary Sub-Contract Agreement.
Kan Ting Chiu SJ found the Plaintiff’s reliance on an “understanding” problematic. The court noted that the Plaintiff’s use of the term did not specify whether it was unilateral or bilateral, or whether it was binding. More importantly, if suspension of demands on the bond was sufficiently important to warrant an express agreement, it would be expected to appear in the Supplementary Sub-Contract Agreement. The court observed that the Supplementary Sub-Contract Agreement contained detailed provisions on completion obligations, payment schedules, withdrawal of certain payment certificates, and the extension of the bond’s validity period to 9 October 2015, while remaining silent on any commitment not to call the bond. This absence undermined the Plaintiff’s assertion that there was a binding understanding not to call.
In other words, the court treated the written agreement as the best evidence of what was agreed. Where the alleged understanding was not recorded, and where the Plaintiff did not contemporaneously document or challenge the omission, the court was not prepared to infer a binding commitment that would justify restraining a bond call. The court therefore concluded that the Plaintiff had not established a strong case on the “no call” understanding.
Turning to the back-charges, the court considered the Plaintiff’s argument that the 1st Defendant imposed back-charges that were unreasonable, inflated, or not contractually entitled. The Plaintiff alleged that back-charges spiked dramatically from June 2015 to December 2015, and it listed categories such as concrete wastage, rebar wastage, labour backcharges for specific blocks, and material supply. The Plaintiff’s narrative was that these back-charges put it in a negative position in the final account and thereby provided the basis for the bond demand.
The court’s approach reflected the same policy concern: an Erinford injunction is not a substitute for a full trial of the underlying contractual accounting. The court was concerned with whether the demand was unconscionable in a way that justified injunctive intervention. While the Plaintiff framed the back-charges as inflated and unconscionable, the court required more than disagreement over calculation or entitlement. The extract indicates that the court found the Plaintiff’s case insufficient to meet the threshold, particularly given the context of the Plaintiff’s non-compliance with the subcontract and the existence of a mechanism for assessing back-charges within the contractual framework.
Although the provided extract truncates the remainder of the judgment, the decision is clear from the outcome: the court did not accept that the Plaintiff had demonstrated unconscionability. The court’s reasoning, as reflected in the analysis of the alleged understanding and the general treatment of back-charges, suggests that the court viewed the dispute as one that could be resolved through the ordinary contractual and accounting processes rather than through an exceptional injunction against bond payment.
What Was the Outcome?
The High Court refused to restrain the holder of the performance bond from making a call on it. The Plaintiff’s application for an interim injunction was therefore dismissed. The court also refused to grant an Erinford order, meaning that the Plaintiff did not obtain the exceptional relief required to interfere with the bond’s payment function.
Practically, this meant that the 1st Defendant was not restrained from receiving payment under the performance bond following its demand, and the 2nd Defendant was not restrained from making payment in accordance with the bond’s terms. The Plaintiff’s claims regarding the alleged understanding and the back-charges would therefore have to be pursued through the substantive dispute resolution process rather than by stopping the bond call at the interim stage.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates the strict approach Singapore courts take when asked to restrain calls on performance bonds. The decision reinforces that performance bonds are meant to be “pay now, argue later” instruments. Courts will not readily infer unconscionability from disputes about contractual performance, accounting, or alleged side understandings that are not clearly reflected in the written contractual documents.
From a drafting and evidence perspective, the judgment highlights the importance of recording any material commitments relating to bond calls in the contract or supplementary agreements. Where parties intend that a bond should not be called, or should be suspended pending final accounts, the court expects clear and contemporaneous documentation. The absence of such provisions in a detailed supplementary agreement, coupled with a lack of contemporaneous objection, can be fatal to an unconscionability argument.
For litigators, the case also underscores that challenging back-charges—especially where the challenge is essentially about entitlement, reasonableness, or quantum—may not meet the high threshold for an Erinford injunction. Even if the underlying accounting is disputed, the court will generally require a stronger showing that the demand itself is unconscionable in the relevant legal sense.
