Summary
Public Prosecutor v Koh Peng Kiat concerned a criminal reference to the Court of Appeal on three questions of public interest arising from a trade-mark and counterfeit health product prosecution. The respondent, an optometrist who operated an optical shop, was convicted in the District Court for (i) abetting offences under s 49(c) of the Trade Marks Act (TMA) relating to goods bearing falsely applied registered trade marks, and (ii) arranging to supply counterfeit contact lenses under s 16(1)(b) of the Health Products Act (HPA). The High Court subsequently allowed the respondent’s appeal against conviction, and the Public Prosecutor referred questions of law to clarify the proper legal approach.
The Court of Appeal’s analysis focused on how mens rea operates in the context of abetment where the primary offence is framed as a statutory offence with defences. It also addressed the structure of the statutory defence in s 49(i) of the TMA, particularly whether an accused must take “all reasonable precautions” before he can show he had “no reason to suspect” the genuineness of the mark. Finally, the Court considered whether the HPA offence under s 16(1)(b) is strict liability such that knowledge of counterfeiting need not be proved.
Although the Public Prosecutor indicated that the reference was not intended to reopen the acquittals, the Court’s answers were intended to guide future prosecutions and to ensure consistent application of statutory defences and mental elements in counterfeit-related offences.
What Were the Facts of This Case?
The respondent, Koh Peng Kiat, was an optometrist and the owner of an optical shop selling spectacles and contact lenses. He had a business partner, Neo Teck Soon, and a friend, Andy Wong, who was also involved in the contact lens trade. Through his work, the respondent came to know a Malaysian man known only as “Ah Seng”. The respondent was told that Ah Seng could procure boxes of FRESHLOOK COLORBLENDS contact lenses from Malaysia at a favourable price.
FRESHLOOK COLORBLENDS was a trade mark registered in Singapore and owned by CIBA Vision Pte Ltd (“CIBA Vision”). The respondent assisted Neo and Wong in purchasing contact lenses from Ah Seng. In Wong’s case, arrangements were made for Wong to pick up 30 boxes of FRESHLOOK COLORBLENDS lenses from the respondent’s shop, paying $8 per box (total $240). In Neo’s case, the respondent suggested that Neo buy lenses from Ah Seng at $10 per box, with the respondent absorbing $7.50 of that price to reduce Neo’s debt. The respondent then arranged for Neo to collect 100 boxes later from a person (purportedly Ah Seng) at a bus stop for $250.
After these purchases, Wong and Neo resold the lenses to others. However, the boxes of contact lenses purchased through the respondent were later found to be counterfeit. The respondent therefore faced multiple charges arising from his role in arranging the supply chain and facilitating possession for commercial purposes.
At trial, the respondent faced 14 charges in total: two charges under s 49(c) of the TMA read with s 107(c) of the Penal Code for abetting by intentionally aiding persons to have in their possession for the purpose of trade goods bearing falsely applied registered trade marks; and 12 charges under s 16(1)(b) of the HPA for arranging to supply counterfeit contact lenses purporting to be FRESHLOOK COLORBLENDS lenses. The District Court found that the respondent played an active and crucial role in arranging the transactions and that he had reasons to suspect the genuineness of the lenses but failed to take reasonable precautions or exercise due diligence.
What Were the Key Legal Issues?
The criminal reference posed three legal questions. The first concerned abetment: whether the statutory defences in s 49 of the TMA are available to a person tried for abetting an offence under s 49(c) of the TMA. This required the Court to consider the relationship between the mental element for abetment and the structure of the primary offence, including the statutory defences that an accused may raise to avoid liability.
The second issue concerned the defence in s 49(i) of the TMA. The question was whether a person seeking to rely on that defence must take “all reasonable precautions” before he can be said to have “no reason to suspect” the genuineness of the mark on goods to which a registered trade mark has been falsely applied. This required the Court to interpret the defence as a composite enquiry and to determine whether the precautions requirement is a condition precedent or merely one factor in assessing suspicion.
The third issue concerned the HPA offence under s 16(1)(b). The Court had to decide whether that offence is one of strict liability such that the prosecution does not have to prove that the accused knew the health product was counterfeit. This implicated how statutory offences are construed, particularly where the statute does not expressly require knowledge.
How Did the Court Analyse the Issues?
In addressing Question 1, the Court of Appeal began by emphasising that abetment cannot be analysed in isolation from the primary offence. The Court reasoned that to determine whether the “shoe fits”, one must first measure the foot: that is, understand the elements of the primary offence under s 49(c) of the TMA and then consider the elements of abetment of that offence. Section 49 provides that a person who imports, sells, or has in possession for the purpose of trade goods to which a registered trade mark is falsely applied is guilty of an offence “unless he proves” specified matters. The statutory defences in s 49(i) and s 49(ii) therefore operate as exceptions to liability, and the prosecution’s burden and the accused’s burden must be understood accordingly.
The Court’s analysis then turned to the mental element required for abetment. Abetment under the Penal Code involves intentional conduct that aids the commission of the primary offence. The Court held that, even if the primary offence is structured as a statutory offence with defences, the abettor’s liability depends on the requisite mens rea for abetment. In other words, the Court did not treat abetment as automatically importing the same mental element as the primary offence’s defences. Instead, it examined whether the statutory defences in s 49 could be invoked by an abettor and, if so, how they interact with the abetment requirement.
On the Court’s reasoning, the statutory defences in s 49 are not simply “available” to any person charged in connection with the offence; rather, their availability turns on the legal structure of the charge and the mental element that must be proved for abetment. The Court therefore clarified that the abettor cannot be convicted without proof of the necessary intentional participation in the primary offence’s commission. Conversely, where the abettor’s state of mind is not established to the required standard, the statutory defences may not be the decisive factor. This approach ensures that abetment remains anchored in mens rea rather than becoming a form of vicarious or strict liability.
In relation to Question 2, the Court analysed the statutory defence in s 49(i) of the TMA. The defence requires that, having taken all reasonable precautions against committing an offence under s 49, the accused had at the time of the commission of the alleged offence no reason to suspect the genuineness of the mark, and that on demand the accused provided information in his power with respect to the persons from whom he obtained the goods. The Court considered whether “all reasonable precautions” is a threshold requirement that must be satisfied before the accused can rely on the “no reason to suspect” limb.
The Court’s interpretation treated the defence as a composite enquiry. It reasoned that the precautions requirement and the absence of reason to suspect are intertwined: the question whether an accused had “no reason to suspect” must be assessed in light of what precautions were taken and what circumstances would have alerted a reasonable person. Accordingly, the Court held that a person cannot selectively rely on the “no reason to suspect” limb without addressing the precautions taken. The statutory design indicates that the accused must demonstrate both that he acted reasonably to prevent the offence and that, given those precautions and the relevant circumstances, he had no reason to suspect the mark’s genuineness.
Practically, this means that courts must scrutinise the accused’s conduct at the time of the transaction, including whether he checked provenance, verified licensing or supply chain legitimacy, and took steps that would be expected of a person dealing in goods bearing registered trade marks. The Court’s approach aligns with the policy of trade mark law: to deter counterfeit trade and to place responsibility on those who handle trade-marked goods to avoid facilitating infringement.
For Question 3, the Court considered whether s 16(1)(b) of the HPA is strict liability. The Court examined the statutory language and the legislative purpose of the HPA, which is to protect consumers and public health by regulating health products and preventing counterfeit or unsafe products from entering the market. The Court’s analysis addressed whether knowledge of counterfeiting is an element that the prosecution must prove, or whether the offence is structured so that liability attaches upon the prohibited conduct (arranging to supply counterfeit health products) without proof of knowledge.
The Court concluded that the HPA offence under s 16(1)(b) is strict liability in the relevant sense. This means that the prosecution does not have to prove that the accused knew the health product was counterfeit. The Court’s reasoning reflected the protective nature of health product regulation and the legislative choice to shift the risk of counterfeit supply onto those who arrange supply. While strict liability may appear harsh, the Court’s interpretation is consistent with the statutory objective of preventing counterfeit goods from being distributed, where reliance on knowledge-based proof would undermine enforcement.
What Was the Outcome?
The Court of Appeal answered the three questions of law in a manner that clarified the interaction between statutory defences and abetment, the structure of the s 49(i) defence, and the mental element required for the HPA offence. Importantly, the Court’s answers were given in the context of a criminal reference where the Public Prosecutor had stated that there was no intention to reopen the respondent’s acquittals following the High Court decision.
As a result, the practical effect of the Court of Appeal’s decision was primarily prospective and doctrinal: it provided authoritative guidance for future cases involving abetment of trade mark offences, the evidential and interpretive requirements for the s 49(i) defence, and the prosecution’s burden for HPA counterfeit supply offences.
Why Does This Case Matter?
Public Prosecutor v Koh Peng Kiat is significant for practitioners because it addresses a recurring enforcement problem at the intersection of trade mark law, criminal participation (abetment), and statutory defences. The decision clarifies that abetment charges cannot be treated as a mere extension of the primary offence’s liability structure. Instead, the Court requires careful attention to the mens rea of abetment and to how statutory defences operate within that framework.
For defence counsel, the case is also important because it provides a structured approach to the s 49(i) defence. The Court’s insistence on a composite enquiry means that an accused’s explanation of “no reason to suspect” must be supported by evidence of reasonable precautions. Practitioners should therefore treat due diligence steps—such as verifying provenance, checking licensing or supply chain legitimacy, and making reasonable enquiries—as central to building a defence under s 49(i).
For prosecutors, the decision provides clarity on evidential burdens. In particular, the Court’s treatment of the HPA offence as strict liability reduces the need to prove knowledge of counterfeiting, thereby strengthening enforcement against those who arrange supply of counterfeit health products. Overall, the case contributes to a coherent doctrinal framework for counterfeit-related offences and will likely influence how charges are framed and how defences are pleaded and assessed.
