Summary
In Hi-P International Limited v Tan Chai Hau (Chen Zaihao) & 2 Ors ([2020] SGHC 128), the High Court considered whether interim injunctive relief should be granted to restrain two former employees from using or disclosing their former employer’s confidential information. The plaintiff, a Singapore-incorporated and publicly listed manufacturer, alleged that the defendants breached confidentiality obligations in their employment contracts and that the first defendant induced the second and third defendants to breach their contractual duties. The plaintiff also sought to restrain the defendants from disclosing trade secrets and confidential information to a competitor group, Kunshan Kersen and its Singapore subsidiary.
The court applied the well-established three-stage framework for interim injunctions: (1) whether there is a serious question to be tried; (2) whether damages would be an adequate remedy; and (3) where the balance of convenience lies. The judge found that the plaintiff had raised a serious question regarding the enforceability of the confidentiality clauses, including whether the restraint was an unreasonable restraint on trade. He also found that the plaintiff had adduced sufficient evidence to raise questions about whether the first and third defendants had breached their confidentiality obligations, particularly in light of the circumstances of their departure and subsequent employment.
Ultimately, the court granted the interim injunctions sought in relation to confidentiality. It also granted leave to adduce further evidence in support of the interim application, and it allowed amendments to the wording of the injunctive prayers to narrow their scope and improve specificity. The decision illustrates how Singapore courts balance an employer’s legitimate interest in protecting trade secrets against former employees’ right to earn a living, while also emphasising the practical importance of drafting sufficiently specific injunctive terms.
What Were the Facts of This Case?
The plaintiff, Hi-P International Limited (“Hi-P”), is a company incorporated and publicly listed in Singapore. It describes itself as a manufacturer and seller of components used across wireless telecommunications, consumer electronics, automotive, and computing industries. The defendants were all former employees of Hi-P. The dispute arose after the defendants left Hi-P and joined companies within the Kunshan Kersen group.
The first defendant, Tan Chai Hau (Chen Zaihao), left Hi-P in April 2019 and later joined Kunshan Kersen Science & Technology Co, Ltd (“Kunshan Kersen”) in October 2019 as its Chief Executive Officer. Kunshan Kersen is a company incorporated and publicly listed in China. The first defendant was also a director of Kersen Science and Technology (Singapore) Pte Ltd (“Kersen Singapore”), a Singapore-incorporated wholly-owned subsidiary of Kunshan Kersen. The plaintiff alleged that Kunshan Kersen and Kersen Singapore were its competitors.
The second defendant, Shih, Cheng-Chieh, allegedly left Hi-P in October 2019 and joined Kunshan Kersen sometime between the end of 2019 and early 2020. The third defendant, Tan Ping Eng, had his last day with Hi-P on 6 September 2019 and joined Kunshan Kersen in October 2019 as Tooling Senior Director. At the time of the interim application, the second defendant was outside Singapore in China and had not yet been served with the writ of summons.
Hi-P commenced the suit claiming that the defendants breached confidentiality, non-solicitation, and non-compete clauses in their employment contracts. It further alleged that the first defendant induced the second and third defendants’ breaches. In addition to damages to be assessed at trial, Hi-P sought a permanent injunction restraining the defendants from revealing trade secrets and confidential information to Kunshan Kersen or Kersen Singapore, poaching employees, customers, and suppliers, and inducing current and former employees to breach their own restrictive covenants.
What Were the Key Legal Issues?
The interim injunction applications required the court to address several interrelated issues. First, the court had to determine whether there was a serious question to be tried. In this context, the serious question included whether the confidentiality clauses in the defendants’ employment contracts were enforceable. The enforceability issue turned on whether the clauses constituted an unreasonable restraint on trade, requiring a balancing exercise between the employer’s legitimate interest in protecting confidential information and the employees’ interest in using their skills and experience to earn a living, alongside the wider public interest in competition.
Second, the court had to consider whether damages would be an adequate remedy if the injunction were refused and the plaintiff ultimately succeeded at trial. This issue is particularly significant in cases involving trade secrets and confidential information because the harm may include loss of goodwill, customer connections, and competitive disadvantage that may be difficult to quantify or reverse through monetary compensation.
Third, the court had to assess the balance of convenience. This involved weighing the risk of injustice to the plaintiff if the injunction were not granted against the risk of injustice to the defendants if it were granted. The court also had to consider whether the injunctive relief sought was appropriately tailored and sufficiently specific, given the defendants’ argument that the plaintiff’s original wording was too broad.
How Did the Court Analyse the Issues?
Before turning to the merits of the interim injunction, the judge dealt with a further evidence application. Hi-P sought leave to adduce additional evidence in support of the interim injunction application. The further evidence was an affidavit by Mr Chen Wang, an employee in Hi-P’s IT department. Mr Chen Wang’s evidence was that in mid-April 2019, shortly before the first defendant left Hi-P, the first defendant asked for assistance with his work laptop. Mr Chen Wang explained that the request required formatting the laptop’s hard drive, which would cause loss of data and affect Hi-P’s ability to investigate whether information had been copied. Mr Chen Wang also recalled the first defendant saying that he had made a backup copy of the data on an external hard drive. However, when the first defendant left, the laptop apparently contained no or few files, and he did not hand any data storage devices to Hi-P.
The judge granted leave to adduce this evidence. He found it relevant to Hi-P’s allegation that the first defendant had taken confidential information when he left, and that this was relevant to whether the first defendant should be restrained on an interim basis from disclosing confidential information. The judge also accepted the plaintiff’s explanation that it only discovered the matter on 14 May 2020 during its investigations, and he found the evidence credible.
Turning to the interim injunction framework, the judge reiterated the three-stage test: (a) whether there is a serious question to be tried; (b) if so, whether damages would be an adequate remedy; and (c) where the balance of convenience lies. Although the application was framed as an interim injunction, the judge noted a procedural drafting issue: the plaintiff’s prayers did not include the usual temporal wording “until the trial of or determination of this action or further order, whichever may be earlier.” The judge treated the prayers as including that wording where appropriate, to avoid the application failing on a technicality.
The court then addressed amendments to the wording of the injunctive prayers. Counsel for Hi-P made an oral application to amend prayers 2 and 3. The judge allowed the amendments but cautioned that belated applications should be avoided. The amended prayers restrained the first and third defendants, pursuant to the confidentiality undertakings in their contracts, from using for their own benefit or revealing to Kunshan Kersen or Kersen Singapore specified categories of trade secrets or confidential information. Importantly, the amended wording tied the prohibited information to the categories listed in the particulars of the statement of claim and related pleadings, rather than using an overly general formulation.
On the “serious question” requirement, the judge found that Hi-P had raised a serious question regarding both enforceability and breach. The enforceability question depended on whether the confidentiality clause was an unreasonable restraint on trade. The judge recognised that this required a difficult balancing exercise between the employer’s legitimate interest in protecting trade secrets and confidential information, and the employees’ interest in using their skills and experience to earn a living, as well as the public interest favouring competition.
Regarding specificity, the defendants argued that Hi-P failed to sufficiently particularise the confidential information it sought to protect. The judge accepted that specificity is a matter of degree and agreed that the original wording of the prayers was too wide because it referred generally to “any trade secrets or confidential information.” However, he held that the amended wording was sufficiently specific: it identified categories of information such that the defendants could understand what they were prohibited from disclosing.
As to breach, the judge considered whether Hi-P had raised sufficient questions about the circumstances surrounding the defendants’ departure and their subsequent employment. He relied on Mr Chen Wang’s evidence to suggest that the first defendant had at least the opportunity to copy Hi-P’s confidential information before leaving. The judge also referred to evidence from other Hi-P officers regarding a tender bid for plastic components for use in speakers. Hi-P alleged that the second and third defendants worked on the tender, resigned in quick succession during preparations, and then joined Kunshan Kersen. Hi-P further alleged that it later learned it had been selected for the tender but ultimately lost it to Kunshan Kersen. The judge also noted that two-thirds of Hi-P’s project team for the tender apparently received calls from Kunshan Kersen soliciting their employment.
While the judge acknowledged that these allegations might be coincidental or not insidious, he concluded that Hi-P’s case was not so frivolous or vexatious that it had no chance of succeeding at trial. He also addressed the adequacy of damages. If the injunction were refused and Hi-P succeeded at trial, damages might not be an adequate remedy. Beyond loss of profits, misuse of trade secrets and confidential information could lead to loss of customer connections and goodwill, as well as workforce disruption, which are not easily compensable in monetary terms.
Finally, on the balance of convenience, the judge considered the risk of injustice. He found that granting prayers 2 and 3 as amended carried a lower risk of injustice than refusing them. He reasoned that the information enumerated in the amended prayers—such as customer lists and quotations for projects—appeared more likely to constitute protectable confidential information rather than mere skills and knowledge of the defendants. This reasoning supported the conclusion that interim restraint was justified to preserve the status quo pending trial.
What Was the Outcome?
The court granted leave for Hi-P to adduce the further evidence affidavit of Mr Chen Wang in support of the interim injunction application. The court also allowed amendments to the wording of the injunctive prayers, narrowing them to specified categories of confidential information tied to the pleadings. This ensured that the interim relief sought was sufficiently precise and not overly broad.
On the merits of the interim injunction application, the judge granted the interim injunctions restraining the first and third defendants from using or disclosing specified trade secrets and confidential information to Kunshan Kersen or Kersen Singapore, pursuant to the relevant confidentiality undertakings in their employment contracts. The practical effect was to prevent the defendants, pending trial, from exploiting or communicating confidential categories identified by Hi-P, thereby protecting the plaintiff’s competitive position while the court assessed the enforceability and alleged breach at a full hearing.
Why Does This Case Matter?
This decision is significant for practitioners dealing with employment-related restrictive covenants and interim injunctive relief in Singapore. First, it demonstrates the court’s willingness to grant interim protection for confidential information where the employer can show a serious question to be tried on enforceability and breach, and where damages may be inadequate. The court’s analysis reflects the reality that trade secret misuse can cause harm that is difficult to quantify, particularly where customer relationships and goodwill are implicated.
Second, the case underscores the importance of drafting and tailoring injunctive relief. The judge accepted that specificity is a matter of degree, but he agreed that overly broad wording (“any trade secrets or confidential information”) is vulnerable to challenge. The amendments in this case show a practical approach: align the prohibited information with categories pleaded in particulars and related documents so that defendants can clearly understand the scope of the restraint.
Third, the decision illustrates how courts assess the balance of convenience in confidentiality cases. The judge treated protectable confidential information (such as customer lists and quotations) as more likely to justify interim restraint than general skills and experience. For employers, this suggests that interim relief is more readily obtained when the employer can identify concrete categories of information rather than seeking blanket restraints. For employees, it signals that courts will scrutinise whether the restraint is genuinely necessary to protect legitimate interests and whether it is proportionate.
