Summary

The judgment in Amber Compounding Pharmacy Pte Ltd and another v Lim Suk Ling Priscilla and others [2023] SGHC 241 represents a significant clarification of the remedial landscape in Singapore’s law of confidence. The central dispute arose from the unauthorized acquisition and use of highly sensitive pharmaceutical data, including formulations and client lists, by former employees to establish a competing business, UrbanRx Compounding Pharmacy Pte Ltd. While the liability of the defendants had largely been established through a prior consent judgment in 2020, the parties remained at an impasse regarding the specific legal framework under which damages should be assessed. This interlocutory application sought a definitive ruling on whether a plaintiff could simultaneously pursue claims based on two distinct interests: the "wrongful gain" interest and the "wrongful loss" interest.

Historically, the law of confidence in Singapore was governed by the three-fold test in Coco v A N Clark (Engineers) Ltd [1969] RPC 41, which focused primarily on the unauthorized use of information to the detriment of the owner—an approach that protected the "wrongful gain" interest. However, the Court of Appeal in I-Admin (Singapore) Pte Ltd v Hong Ying Ting and others [2020] 1 SLR 1130 introduced a "modified approach" designed to protect the "wrongful loss" interest, which is triggered by the mere unauthorized acquisition or circulation of confidential material, regardless of whether it was subsequently used. The defendants in the present case argued that these two interests were mutually exclusive and that the plaintiffs must elect one framework, contending that the I-Admin approach was intended to replace the Coco approach in specific "taker" scenarios.

Dedar Singh Gill J rejected the defendants' restrictive interpretation, holding that the "wrongful gain" and "wrongful loss" interests are not mutually exclusive. The court determined that a plaintiff is entitled to plead and claim that both interests have been infringed by a defendant's conduct. This decision establishes that the I-Admin framework does not supersede the Coco framework but rather supplements it to ensure that the law provides a robust response to different types of harm. The court's ruling ensures that a plaintiff who has suffered both the loss of control over their secrets (wrongful loss) and the subsequent exploitation of those secrets by a competitor (wrongful gain) can seek comprehensive equitable and compensatory relief.

The doctrinal contribution of this case lies in its affirmation of the cumulative nature of these interests. By allowing plaintiffs to proceed on both fronts, the High Court has reinforced the principle that the law of confidence protects not just the commercial value of information, but the very "sanctity of the secret" itself. This judgment provides essential guidance for practitioners in drafting pleadings and preparing for the assessment of damages in intellectual property disputes, confirming that the "modified approach" from I-Admin is a permanent and versatile fixture of Singapore's legal architecture.

What Were the Facts of This Case?

The first plaintiff, Amber Compounding Pharmacy Pte Ltd, is a specialized pharmaceutical entity incorporated in Singapore on 6 March 2008. Its core business involves the "compounding" of medical and pharmaceutical products—a process where medications are customized to meet the specific needs of individual patients. The second plaintiff, Amber Laboratories Pte Ltd, provides essential support services to the first plaintiff. Together, they built a significant repository of proprietary information, which they categorized as confidential and trade secrets. This information included complex pharmaceutical formulations, detailed price lists, and comprehensive client lists, all of which were central to their competitive advantage in the niche compounding market.

The dispute centered on the actions of several former employees and a new corporate entity. The first defendant, Priscilla Lim Suk Ling, the third defendant, Muhammad ‘Ainul Yaqien Bin Mohamed Zin, and the fifth defendant, Tee I-Lin Cheryl, were all previously employed by the plaintiffs. During their tenure, they had access to the plaintiffs' confidential databases. The second defendant, UrbanRx Compounding Pharmacy Pte Ltd, was incorporated on 28 April 2017. The first and fourth defendants (Daniel James Tai Hann) served as directors of UrbanRx, while the sixth defendant (Tan Bo Chuan) is the husband of the first defendant.

The plaintiffs alleged a systematic misappropriation of their intellectual property. Specifically, they claimed that the defendants copied confidential documents and used that information to establish and operate UrbanRx. The allegations included the unauthorized use of pharmaceutical formulations to create competing products, the utilization of price lists to undercut the plaintiffs, and the direct solicitation of the plaintiffs' clients using stolen contact information. Furthermore, the plaintiffs alleged that their confidential information had been revealed to third parties without authorization.

The litigation progressed to a significant milestone on 14 September 2020, when a Consent Judgment was entered. In this judgment, the first, second, third, fourth, and sixth defendants were found liable. Crucially, the first and second defendants (Priscilla Lim and UrbanRx) "unconditionally admitted to the unauthorised copying and breach of confidence in relation to the Plaintiffs’ Confidential Information" (at [7]). This admission established the fact of the breach, leaving the court to determine the appropriate measure of relief.

The plaintiffs sought to recover damages on two distinct bases. First, they sought damages for the "wrongful gain" the defendants achieved by using the information to run UrbanRx, following the traditional Coco approach. Second, they sought equitable damages for the "wrongful loss" they suffered due to the mere fact that the defendants had unauthorized possession of their secrets, following the "modified approach" established by the Court of Appeal in I-Admin. The defendants resisted this dual-track approach, leading to the filing of Summons No 1589 of 2023. The defendants' position was that the I-Admin approach was a replacement for the Coco approach in cases involving the unauthorized taking of information (the "taker" scenario), and that allowing both would result in double recovery or legal inconsistency.

The evidence record for this application included the affidavit of Jayne Wee Shir Li dated 30 May 2023, which detailed the nature of the confidential materials and the extent of the defendants' access. The Statement of Claim (Amendment No. 2) served as the foundational pleading, setting out the specific formulations and lists that were the subject of the breach. The procedural history of the suit, spanning from its filing in February 2018 to the 2020 Consent Judgment, framed the legal question: whether the plaintiffs' pleadings could validly encompass both the Coco and I-Admin frameworks for the purpose of the upcoming assessment of damages.

What Were the Key Legal Issues?

The primary legal issue before the High Court was a narrow but foundational question of pleading and remedial law: whether a plaintiff in a claim for breach of confidence is entitled to plead and claim that both its "wrongful gain" interest and its "wrongful loss" interest have been infringed by the defendant.

This issue required the court to resolve the following sub-questions:

• The Relationship Between Coco and I-Admin: Does the "modified approach" introduced in I-Admin (Singapore) Pte Ltd v Hong Ying Ting and others [2020] 1 SLR 1130 replace the traditional Coco v A N Clark (Engineers) Ltd [1969] RPC 41 test in "taker" cases, or do they coexist as alternative or cumulative frameworks?
• The Definition of Protected Interests: What are the distinct legal interests protected by the "wrongful gain" and "wrongful loss" categories, and can a single set of facts (the unauthorized taking and subsequent use of information) infringe both interests simultaneously?
• The Impact of Subsequent Dicta: How should the court interpret subsequent High Court decisions, such as [2022] SGHC 205 and [2023] SGHC 34, which appeared to suggest a more bifurcated application of the two approaches?
• Pleading Specificity: To what extent must a plaintiff specify which interest they are proceeding upon at the pleading stage, and does the election of one preclude the other?

The resolution of these issues was critical because it determined the scope of the evidence and the methodology for calculating damages in the assessment phase. If the defendants were correct, the plaintiffs would be forced to choose between a claim based on the defendants' profits/use (wrongful gain) and a claim based on the loss of confidentiality itself (wrongful loss), potentially leaving certain aspects of the harm uncompensated.

How Did the Court Analyse the Issues?

Dedar Singh Gill J began the analysis by tracing the evolution of the law of confidence in Singapore. He noted that the traditional Coco approach required three elements: (a) the information must have the necessary quality of confidence; (b) the information must have been imparted in circumstances importing an obligation of confidence; and (c) there must be an unauthorized use of the information to the detriment of the party communicating it (at [11]).

The court then contrasted this with the landmark decision in I-Admin (Singapore) Pte Ltd v Hong Ying Ting and others [2020] 1 SLR 1130 ("I-Admin (CA)"). In that case, the Court of Appeal recognized that the Coco approach, with its heavy emphasis on "unauthorized use," failed to adequately protect the "wrongful loss interest"—the interest of a confider in maintaining the secrecy of their information. The Court of Appeal in I-Admin (CA) introduced a modified approach: once the first two Coco elements (quality and obligation of confidence) are met, a breach is presumed if the defendant has acted in a way that impinges on the plaintiff's conscience, such as through unauthorized acquisition or circulation. The burden then shifts to the defendant to prove their conscience was not affected.

Reason 1: No Conflicting Binding Precedent

The court first addressed whether any binding precedent from the Court of Appeal prohibited the simultaneous pleading of both interests. The defendants argued that I-Admin (CA) and the subsequent decision in Lim Oon Kuin and others v Rajah & Tann Singapore LLP and another appeal [2022] 2 SLR 280 ("Lim Oon Kuin") suggested that the frameworks were mutually exclusive. In Lim Oon Kuin, the Court of Appeal noted that different analytical frameworks apply depending on whether the case is a "taker" case (where the I-Admin approach applies) or a "user" case (where the Coco approach applies).

However, Dedar Singh Gill J found that these cases did not mandate an "either/or" choice for the plaintiff. He observed that while Lim Oon Kuin clarified the application of the frameworks, it did not state that they could not both be invoked if the facts supported both unauthorized acquisition and unauthorized use. The court noted that the Court of Appeal in I-Admin (CA) explicitly stated:

"A question that follows is whether there is a threat to this wrongful loss interest that warrants a more robust response by the law. The elements of breach of confidence set out in Coco ([20] supra) explicitly protect the wrongful gain interest. Although there is often a degree of overlap, it may not always be the case that a defendant’s conduct will affect both the wrongful gain and wrongful loss interests." (at [20], quoting I-Admin (CA))

This passage, the court reasoned, acknowledged that both interests could be affected simultaneously. Therefore, there was no binding authority preventing a plaintiff from claiming that both interests had been infringed.

Reason 2: The Rationale for the Interests

The court’s second reason focused on the distinct nature of the interests protected. The "wrongful gain interest" is concerned with preventing a defendant from profiting from the unauthorized use of confidential information. The "wrongful loss interest," conversely, is concerned with the loss suffered by the plaintiff when their confidential information is accessed or circulated without consent, regardless of use.

Dedar Singh Gill J emphasized that these are two distinct harms. A defendant who steals a secret formula (infringing the wrongful loss interest) and then uses it to manufacture a product (infringing the wrongful gain interest) has committed two distinct wrongs. The court held that it would be logically inconsistent to force a plaintiff to choose only one interest to protect when both have been violated. The I-Admin approach was designed to "supplement" the Coco approach, not to "supplant" it. The court noted that the I-Admin approach provides a "more robust response" to the wrongful loss interest, but this does not diminish the plaintiff's right to also seek redress for the wrongful gain interest under the Coco framework.

Reason 3: No Conflicting High Court Dicta

The defendants relied heavily on the High Court decision in [2022] SGHC 205 ("Writers Studio"), where Lee Seiu Kin J stated that "counsel should take care to plead with specificity, whether they are proceeding on the basis of the 'wrongful loss' or 'wrongful gain' interest" (at [24]). The defendants argued this meant a plaintiff must choose one.

Dedar Singh Gill J disagreed with this interpretation. He clarified that the call for "specificity" in Writers Studio was a procedural requirement to ensure the defendant knows the case they have to meet, not a substantive bar to pleading both. He noted that in Writers Studio, the plaintiff had failed to clearly identify which interest was being invoked, leading to confusion. In contrast, if a plaintiff clearly pleads that they are proceeding on both interests, the requirement for specificity is satisfied.

The court also considered [2023] SGHC 34 ("Shanghai Afute"), where the court applied the Coco approach because the plaintiff's case was framed around the "unauthorized use" of information. Dedar Singh Gill J noted that Shanghai Afute merely demonstrated that the Coco approach remains relevant and applicable; it did not suggest that the I-Admin approach could not have been pleaded alongside it had the facts warranted it.

Ultimately, the court concluded that the two approaches are "complementary" (at [31]). The I-Admin approach addresses the "wrongful loss" caused by the acquisition of information, while the Coco approach addresses the "wrongful gain" caused by its use. A plaintiff who proves both is entitled to remedies for both, subject to the rule against double recovery.

What Was the Outcome?

The High Court ruled in favor of the plaintiffs, answering the central question in the affirmative. The court issued a declaration regarding the proper pleading of breach of confidence claims in Singapore.

The operative conclusion of the court was stated as follows:

"In conclusion, a plaintiff is entitled to plead that it is proceeding on both the wrongful gain interest and the wrongful loss interest in a claim for breach of confidence and therefore claim for both damages under the Coco approach and equitable damages under the I-Admin approach." (at [32])

The court's orders effectively allowed the plaintiffs to proceed to the assessment of damages phase on a dual-track basis. They are permitted to seek:

• Damages under the Coco approach: To compensate for the "wrongful gain" achieved by the defendants through the unauthorized use of the pharmaceutical formulations, price lists, and client lists in the operation of UrbanRx.
• Equitable damages under the I-Admin approach: To compensate for the "wrongful loss" interest, reflecting the harm caused by the defendants' unauthorized acquisition and possession of the confidential materials, independent of their subsequent use.

Regarding costs, while the judgment does not detail a specific quantum for the interlocutory application, it sets the stage for the final disposition of the suit. The court's decision ensures that the assessment of damages will be comprehensive, covering the full spectrum of the defendants' admitted breaches. The court noted that while both interests can be pleaded and claimed, the final award will be subject to the standard legal principle against double recovery—meaning the plaintiffs cannot be compensated twice for the same underlying economic loss, but they can be compensated for the distinct types of harm represented by the two interests.

The direction of the court was a clear affirmation of the plaintiffs' right to leverage the full suite of protections afforded by the evolving law of confidence in Singapore. The defendants' attempt to restrict the plaintiffs to a single remedial framework was rejected in its entirety.

Why Does This Case Matter?

The significance of Amber Compounding Pharmacy v Priscilla Lim lies in its role as a "bridge" between the traditional and modern frameworks of Singapore’s law of confidence. For decades, the Coco test was the sole arbiter of such disputes, but its focus on "use" created a remedial gap in cases where information was stolen but not yet exploited, or where exploitation was difficult to prove. The Court of Appeal’s decision in I-Admin (CA) was a revolutionary step to close this gap by recognizing the "wrongful loss interest." However, I-Admin (CA) left open the question of how these two frameworks interact in practice. This judgment provides the answer: they are cumulative, not alternative.

For the Singapore legal landscape, this case confirms that the "modified approach" in I-Admin is not a niche exception for rare "taker" cases, but a fundamental pillar of the law of confidence that can be invoked alongside traditional claims. It reinforces the idea that confidential information has intrinsic value beyond its immediate commercial utility. By protecting the "wrongful loss interest," the court is protecting the owner's right to keep a secret a secret. This is a powerful deterrent against industrial espionage and the misappropriation of data by departing employees, as liability (and potentially equitable damages) can now be established the moment the information is unauthorizedly acquired, without waiting for the competitor to launch a product.

Practitioners must take note of the court's emphasis on pleading. While the court allowed both interests to be pleaded, it did not give a license for vague or "scattergun" pleadings. The reliance on Writers Studio underscores that counsel must be precise. A well-drafted Statement of Claim should now explicitly delineate the facts supporting the "wrongful loss" (the acquisition/taking) and the facts supporting the "wrongful gain" (the use/exploitation). This clarity is essential for the "burden-shifting" mechanism of the I-Admin approach to function correctly, as the defendant must know exactly which acts are alleged to have impinged upon their conscience.

Furthermore, the case has significant implications for the assessment of damages. By allowing claims for both interests, the court has opened the door to more sophisticated valuation methodologies. Plaintiffs can now argue for a "user principle" fee for the wrongful gain while simultaneously seeking equitable compensation for the loss of the "head start" or the permanent loss of confidentiality. This dual approach ensures that the remedy is truly commensurate with the totality of the breach.

Finally, the decision aligns Singapore with a more modern, property-like conception of confidential information, even while the law officially maintains that confidence is rooted in equity and conscience. By providing a "robust response" to the unauthorized taking of information, the Singapore courts are signaling to the global business community that the jurisdiction takes the protection of trade secrets and proprietary data extremely seriously. This judgment is a vital reference point for any practitioner involved in intellectual property litigation, employment disputes involving restrictive covenants, or data breach scenarios.

Practice Pointers

• Plead Both Interests Explicitly: When acting for a plaintiff in a "taker" scenario, ensure the Statement of Claim explicitly invokes both the "wrongful gain" interest (under the Coco approach) and the "wrongful loss" interest (under the I-Admin approach) to maximize remedial options.
• Specificity is Mandatory: Following the dictum in [2022] SGHC 205, counsel must plead with specificity the acts of unauthorized acquisition versus the acts of unauthorized use. Failure to distinguish these may lead to procedural challenges or a refusal by the court to apply the I-Admin burden-shifting framework.
• Identify "Taker" vs "User" Facts: Carefully categorize the evidence. "Taker" facts (e.g., downloading databases, BCC-ing emails to personal accounts) trigger the I-Admin presumption. "User" facts (e.g., incorporating the data into a new product, contacting the plaintiff's clients) support a traditional Coco claim.
• Prepare for Burden Shifting: In I-Admin claims, once the plaintiff establishes the quality of confidence and the unauthorized acquisition, the burden shifts to the defendant. Plaintiffs should prepare to rebut any defense that the defendant's "conscience was not affected."
• Avoid Double Recovery: While both interests can be claimed, practitioners must be prepared to assist the court in the assessment phase to ensure that the damages awarded for wrongful gain and wrongful loss do not overlap to compensate for the same economic injury twice.
• Utilize Consent Judgments Strategically: As seen in this case, obtaining a consent judgment on liability that includes an admission of "unauthorized copying" provides a powerful foundation for invoking the I-Admin framework during the assessment of damages.
• Evidence of "Conscience": For defendants, the focus must be on proving that the acquisition of information was not "unconscionable" or that the information was not actually "confidential" in the way the plaintiff alleges, to prevent the I-Admin presumption from taking hold.

Subsequent Treatment

As a 2023 decision, Amber Compounding Pharmacy Pte Ltd and another v Lim Suk Ling Priscilla and others [2023] SGHC 241 stands as a contemporary and authoritative clarification of the I-Admin framework. It has solidified the "dual-interest" approach in the High Court, ensuring that the "wrongful loss" interest is treated as a cumulative rather than alternative basis for relief. The ratio—that a plaintiff is entitled to plead both interests—has provided a clear procedural roadmap for subsequent breach of confidence cases, particularly those involving the misappropriation of trade secrets by former employees. It effectively reconciles the perceived tensions between I-Admin, Lim Oon Kuin, and Writers Studio, establishing a harmonious remedial structure.
