Summary
The decision in Tritech Water Technologies Pte Ltd and others v Duan Wei and another [2023] SGHC 23 represents a significant exploration of the boundaries of employee loyalty, the rigours of the law of confidence, and the high evidentiary threshold required to sustain a claim in fraud. The dispute arose from the alleged betrayal of the Tritech Group by two senior employees, Dr. Duan Wei (the first defendant) and Mr. Luo Zhuobiao (the second defendant), who were accused of misappropriating highly sensitive technical information to establish a competing enterprise, Dreamem, while still in the plaintiffs' employ. The plaintiffs, a group of engineering and technology companies listed on the Singapore Stock Exchange, sought redress for a series of misrepresentations regarding the procurement of industrial production lines and the systematic theft of trade secrets.
At the heart of the litigation was the "FO Project" and the "RO Production Line." The plaintiffs alleged that Dr. Duan, acting as the Chief Technical Officer, made fraudulent or negligent misrepresentations that induced the plaintiffs to purchase substandard or second-hand equipment at inflated prices from suppliers with whom Dr. Duan had undisclosed connections. Furthermore, the plaintiffs contended that the defendants utilized Tritech’s proprietary "Technical Information"—comprising membrane formulas, production parameters, and supplier lists—to manufacture identical products under the Dreamem brand. This necessitated a deep dive into the I-Admin framework for breach of confidence and the specific duties of care and skill owed by senior technical officers in a corporate hierarchy.
The court’s judgment is particularly notable for its application of the "modified" I-Admin test, which shifts the burden of proof to the defendants once a prima facie case of confidential information and a relationship of confidence is established. Valerie Thean J meticulously parsed the technical evidence, including expert testimony, to determine whether the defendants had indeed "crossed the line" from using general skill and knowledge to misappropriating specific trade secrets. The result was a comprehensive victory for the plaintiffs on several fronts, including findings of fraudulent misrepresentation regarding the RO Production Line and a systematic breach of confidence.
Beyond the immediate commercial stakes, the case serves as a cautionary tale for practitioners regarding the necessity of robust expert evidence. The court’s rejection of certain expert findings due to a lack of analytical depth underscores the judiciary's demand for experts to provide the "why" and "how" behind their conclusions, rather than mere bald assertions. Ultimately, the judgment reinforces the protection afforded to employers against "shadow" businesses operated by fiduciaries and senior employees, providing a clear roadmap for the recovery of losses resulting from such clandestine operations.

What Were the Facts of This Case?
The plaintiffs are part of the Tritech Group, a Singapore-listed entity specializing in urban infrastructure and water technology. The first plaintiff, TWT, served as the R&D hub for water treatment. The second plaintiff, TET, and the third plaintiff, TEG, were involved in engineering and environmental group operations respectively. The dispute centered on the conduct of Dr. Duan Wei, a highly qualified researcher with a PhD in membrane technology, and Mr. Luo Zhuobiao, a senior commercial officer. Dr. Duan was hired specifically to spearhead Tritech’s expansion into the membrane market, a move aimed at diversifying the group's revenue streams beyond traditional engineering services.
In 2011, Tritech embarked on the "FO Project," which involved setting up a commercial production line for Forward Osmosis membranes. Dr. Duan was tasked with identifying suitable suppliers. He recommended Shanghai Dahe, a company he claimed had the necessary expertise. However, the plaintiffs later discovered that Dr. Duan had a pre-existing relationship with the principals of Shanghai Dahe and that the price paid for the FO Production Line (approximately RMB 4,000,000) was significantly inflated. The plaintiffs alleged that the equipment delivered was defective and did not meet the promised technical specifications, leading to a total failure of the FO Project.
The second major factual pillar concerned the "RO Production Line" (Reverse Osmosis). In 2013, Dr. Duan recommended the purchase of a production line from a company called Zhejiang Shengshi for RMB 4,000,000. He represented to the Tritech board that this was a brand-new, state-of-the-art production line. In reality, the equipment was second-hand, having been previously used by another company, and was plagued by mechanical issues. The plaintiffs alleged that Dr. Duan knowingly deceived them to facilitate a transaction that benefited his associates at Zhejiang Shengshi.
Simultaneously, while still drawing salaries from Tritech, Dr. Duan and Mr. Luo were allegedly building a "shadow" business. They incorporated Dreamemway in Singapore and established Dreamem (China) in 2014. The plaintiffs’ case was that the defendants systematically exfiltrated "Technical Information" from Tritech’s servers. This information included "Blueprints" for production lines, "Formulas" for chemical casting solutions (such as the PVDF formula), "Production Parameters" (temperature, speed, and humidity settings), and "Supplier Lists." The plaintiffs provided evidence that Dreamem’s products were virtually identical to those developed by Tritech, and that Dreamem had even used Tritech’s proprietary test reports to market its own products.
The defendants’ primary defense was that the information they used was "general skill and knowledge" common in the membrane industry. They argued that the formulas were based on publicly available academic papers and that the production lines were standard industrial equipment. Dr. Duan further contended that any failures in the FO or RO projects were due to Tritech’s own lack of investment and management failures, rather than any misrepresentation or breach of duty on his part. He also raised a limitation defense, arguing that the claims regarding the FO Project were time-barred under the Limitation Act as the events occurred more than six years before the suit was filed.
The trial involved extensive technical evidence, including a comparison of the chemical compositions of the membranes and the mechanical designs of the production lines. The court had to navigate conflicting expert reports and a mountain of internal emails and WeChat messages that the plaintiffs recovered from the defendants' company-issued devices. These messages proved critical in establishing the defendants' clandestine activities and their intent to compete with their employer.
What Were the Key Legal Issues?
The case presented five primary legal issues that required the court's determination:
- Actionable Misrepresentation: Did Dr. Duan make fraudulent or negligent misrepresentations regarding the FO Production Line, the MR Machines, and the RO Production Line? This involved determining whether the statements were of fact or opinion, whether they were false, and whether Dr. Duan acted with the requisite mens rea (dishonesty or negligence).
- Breach of Confidence: Did the defendants misuse Tritech’s "Technical Information"? The court had to apply the three-part test from Coco v AN Clark (Engineers) Ltd as modified by the Court of Appeal in I-Admin (Singapore) Pte Ltd v Hong Ying Ting and others [2020] 1 SLR 1130.
- Breach of Contractual and Fiduciary Duties: Did the defendants breach their express and implied duties of good faith, fidelity, and the duty to exercise reasonable care and skill? A sub-issue was whether Dr. Duan, as CTO, owed fiduciary duties to the plaintiffs.
- Unlawful Means Conspiracy: Did Dr. Duan and Mr. Luo combine with the intent to cause injury to the plaintiffs by using unlawful means (i.e., the breaches of contract and confidence)?
- Limitation of Actions: Were the claims relating to the FO Production Line (dating back to 2011/2012) barred by the Limitation Act, or did the "fraud or concealment" exception in Section 29 apply?
How Did the Court Analyse the Issues?
The court’s analysis began with the claims of misrepresentation. Valerie Thean J applied the established tests for fraudulent misrepresentation from Panatron Pte Ltd and another v Lee Cheow Lee and another [2001] 2 SLR(R) 435 and Derry v Peek (1889) 14 App Cas 337. For the RO Production Line, the court found that Dr. Duan had represented the equipment as "new" when he knew it was "second-hand." The court noted at [89] that Dr. Duan’s explanation—that "new" could mean "newly purchased"—was commercially nonsensical in the context of a multi-million dollar industrial procurement. The court held this was a fraudulent misrepresentation because Dr. Duan made it "knowingly" or "without belief in its truth."
Regarding the FO Production Line, the court found that Dr. Duan’s representations about the supplier's capability were negligent rather than fraudulent. Applying the test for negligent misrepresentation, the court held that Dr. Duan owed a duty of care to provide accurate technical advice to the board. He breached this duty by failing to conduct adequate due diligence on Shanghai Dahe. On the issue of limitation, the court invoked Section 29 of the Limitation Act. The court found that Dr. Duan had "deliberately concealed" the true nature of his relationship with the suppliers and the defects in the machinery, meaning the limitation period only began to run when the plaintiffs discovered the fraud in 2017.
The analysis of the Breach of Confidence claim was the most technically demanding. The court followed the I-Admin framework, which asks: (a) is the information confidential? and (b) was it imparted in circumstances importing an obligation of confidence? Once these are met, a "legal presumption" of breach arises if the defendant has used the information without consent. The court scrutinized the "Technical Information," specifically the PVDF formula and the production blueprints. The court rejected the defendants' argument that these were "public domain" because they were based on academic papers. The court held at [104] that the specific "combination" of ingredients and the "precise parameters" (the "springboard") constituted protectable confidential information.
"Whether or not the maker of the statement genuinely held the opinion at the time it was made is a question of fact to be determined by the court... a statement of opinion may be a representation of fact if the person making the statement does not actually hold that opinion, or if the statement implies that the person knows facts which justify his opinion." (at [54], citing Smith v Land and House Property Corporation)
The court was highly critical of the defendants' expert witness, Dr. Yang. Applying the principles from Wong Tian Jun De Beers v Public Prosecutor [2022] 4 SLR 805 and Public Prosecutor v Chia Kee Chen and another appeal [2018] 2 SLR 249, the court found Dr. Yang’s report lacked "utility" because it consisted of "bald assertions" without explaining the underlying scientific reasoning. In contrast, the plaintiffs' expert provided a detailed "step-by-step" comparison that demonstrated the substantial similarity between Tritech’s and Dreamem’s processes.
On Fiduciary Duties, the court referred to Clearlab SG Pte Ltd v Ting Chong Chai and others [2015] 1 SLR 163. While not every employee is a fiduciary, the court found that Dr. Duan’s role as CTO, where he had "unilateral discretion" over technical procurement and R&D, placed him in a position of trust. His failure to disclose his interest in the suppliers and his active competition through Dreamem were clear breaches of both fiduciary duty and the implied term of "fidelity" in his employment contract, as articulated in Man Financial v Wong Bark Chuan David [2008] 1 SLR(R) 663.
Finally, for Unlawful Means Conspiracy, the court applied the test from EFT Holdings, Inc and another v Marinteknik Shipbuilders (S) Pte Ltd and another [2014] 1 SLR 860. The court found that Dr. Duan and Mr. Luo had "combined" to set up Dreamem using Tritech’s resources and information, with the clear intent to divert business away from Tritech. The "unlawful means" were the breaches of contract and confidence already established.
What Was the Outcome?
The court ruled substantially in favor of the plaintiffs. The primary orders were as follows:
- Misrepresentation: Dr. Duan was held liable for fraudulent misrepresentation regarding the RO Production Line and negligent misrepresentation regarding the FO Production Line and MR Machines.
- Breach of Confidence: Both Dr. Duan and Mr. Luo were found liable for breaching their duties of confidence by misappropriating the Technical Information.
- Breach of Contract/Fiduciary Duty: Dr. Duan was found to have breached his fiduciary duties and his employment contract. Mr. Luo was found to have breached his contractual duty of fidelity.
- Conspiracy: Both defendants were held liable for unlawful means conspiracy.
- Injunctions: The court granted permanent injunctions restraining the defendants from using or disclosing the plaintiffs' confidential Technical Information.
- Damages: The court ordered that damages be assessed. This includes the wasted expenditure on the FO and RO lines, and either damages for loss of profits or an account of profits made by Dreamem.
- Specific Sums: The court noted various misappropriated sums, including RMB 400,000 related to the RO line and other amounts such as RMB 149,800 and RMB 100,000.51 identified in the evidence.
"Parties are to write in within 14 days regarding with their submissions on costs." (at [138])
The court dismissed the defendants' counterclaims for unpaid salary and expenses, finding that their fundamental breaches of contract disentitled them to such claims. The plaintiffs were also awarded interest on the damages to be assessed, calculated from the date of the writ.
Why Does This Case Matter?
This judgment is a landmark for practitioners dealing with employee-led competition and trade secret theft. First, it provides a robust application of the I-Admin "modified" test for breach of confidence. By shifting the burden to the defendants once a prima facie case is made, the court acknowledges the inherent difficulty plaintiffs face in proving exactly how a defendant used stolen digital data. This "presumption of injury" is a powerful tool for employers in the digital age.
Second, the case clarifies the standard of expert evidence required in technical disputes. The court's refusal to accept "bald assertions" from an expert, even one with relevant academic credentials, serves as a stern reminder that experts must provide a transparent analytical trail. Practitioners must ensure their experts do not just state a conclusion (e.g., "the formulas are different") but demonstrate the scientific basis for that conclusion (e.g., "the molecular weight distribution differs because...").
Third, the decision reinforces the reach of the Limitation Act in cases of "deliberate concealment." In complex technical frauds, it may take years for an employer to realize they have been duped. The court’s willingness to look past the six-year statutory limit where a defendant has actively hidden their tracks (by misrepresenting equipment as "new" or concealing supplier relationships) provides essential protection for victims of sophisticated corporate fraud.
Fourth, the case delineates the fiduciary duties of C-suite technical officers. It confirms that a CTO’s role is not merely technical but involves a high degree of discretionary power over the company’s assets and future. This triggers fiduciary obligations that go beyond the standard duty of fidelity, particularly regarding the disclosure of conflicts of interest in procurement.
Finally, the judgment highlights the evidentiary value of digital forensics. The recovery of WeChat messages and deleted files from company laptops was the "smoking gun" that linked the defendants to Dreamem. This underscores the importance for companies to have clear IT policies that allow for the inspection of company-issued devices upon termination of employment.
Practice Pointers
- Supplier Due Diligence: Companies should implement independent verification processes for high-value technical procurements. Relying solely on the recommendation of a single technical officer, even a CTO, creates a significant risk of undisclosed conflicts or fraud.
- Expert Engagement: When engaging technical experts, counsel must insist on a "reasoned" report. Avoid experts who provide "conclusory" opinions. The report should explicitly address the "why" and "how," as per the standards in Wong Tian Jun De Beers.
- Confidentiality Protocols: To benefit from the I-Admin presumption, companies must clearly identify what information is "confidential." Marking documents, using access controls, and maintaining "Supplier Lists" as restricted data are essential steps.
- Section 29 Limitation Strategy: When faced with a limitation defense in fraud cases, focus on "deliberate concealment." Evidence that a defendant provided misleading reports or used "shadow" entities can successfully toll the limitation period.
- Fiduciary Clauses: Employment contracts for senior technical roles should explicitly state that the employee owes fiduciary duties. While the court may imply these, an express clause provides a stronger contractual basis for claims.
- Interim Relief: In cases of suspected "shadow" businesses, consider applying for Anton Piller (search) orders or Mareva (freezing) injunctions early to preserve digital evidence and prevent the dissipation of assets.
Subsequent Treatment
As a 2023 decision, Tritech v Duan Wei is currently a leading authority on the application of the I-Admin framework in the context of industrial manufacturing. It has been cited for its clear exposition on the distinction between "general skill and knowledge" and "trade secrets," and for its rigorous approach to the assessment of expert testimony in the General Division of the High Court.
