Summary
In Alterm Consortech Pte Ltd v Public Prosecutor ([2013] SGHC 189), the High Court (Choo Han Teck J) allowed appeals by a company and two individuals against convictions under the Copyright Act. The charges related to alleged copyright infringement involving termite barrier specifications and drawings associated with a rival company, Termi-mesh Singapore Pte Ltd (“TSPL”). The complainant, Cheng Wai Meng (“CWM”), claimed he created the copyright-protected specifications and drawings and that the appellants had infringed them in the course of termite barrier installation work.
The court’s decision turned on fundamental evidential and charging defects. The judge found that the charges were flawed because important particulars—specifically, the exact copyrighted articles alleged to have been infringed—were not properly set out and did not correspond with the documentary evidence adduced at trial. In addition, the prosecution’s proof of key elements, including distribution of the infringing specifications and the mental element for individual liability (particularly for the employee appellant), was insufficient. The convictions were therefore set aside, and the fines were ordered to be refunded.
What Were the Facts of This Case?
The first appellant, Alterm Consortech Pte Ltd, carried on pest control business, with a particular focus on termite control. The second appellant, Chew Choon Ling Michael, was the managing director of the first appellant. The third appellant, Teng Siew Chin, was an employee of the first appellant. The three appellants were charged under s 136(3)(a), s 136(2)(b) and s 136(3A) of the Copyright Act, arising from alleged infringement of copyright in termite barrier specifications and drawings.
The complainant, CWM, was the managing director of TSPL, a rival termite control company. CWM alleged that he was the creator of the copyright-protected “Termi-mesh specification and markings on construction drawings” for the proposed installation of the “Termi-mesh Barrier System”. The system was a physical barrier intended to prevent termites from passing through. CWM’s case was that his specifications and TSPL’s markings appeared in the first appellant’s possession and were used in connection with construction drawings for a project known as “The St Regis Project”.
At trial, the court below found that CWM came to know of the alleged breaches sometime in 2006 after comparing a drawing admitted as “P7” with TSPL’s specifications admitted as “P4”. CWM testified that specifications provided by him to an architect company (DP Architects) were later found in the first appellant’s possession. He also claimed that TSPL’s markings were found on drawings given by the first appellant to a contractor known as Kajima. Although TSPL submitted its specifications and construction drawings to the main contractor and architect, TSPL was not ultimately appointed to provide the anti-termite barrier system; instead, the job was given to the first appellant.
On appeal, the appellants advanced multiple defences. First, they argued there was no basis for TSPL to claim copyright in the specifications and drawings, contending that the drawings were mere tracings by TSPL of original drawings provided to TSPL by the main contractor. Secondly, they argued they did not know that TSPL were the copyright owners. Thirdly, they argued their specifications were not distributed to the alleged recipients as claimed by the complainant. Counsel for the appellants further emphasised that the documents in question were obtained through architects and third parties, and that the appellants had no reason to assume that copyright ownership lay with TSPL rather than the architects who supplied the documents.
What Were the Key Legal Issues?
The High Court had to determine whether the convictions could stand in light of (i) the adequacy and correctness of the charges, (ii) whether the prosecution proved the elements of the offences under the Copyright Act beyond reasonable doubt, and (iii) whether the evidence supported the requisite mental element and participation for the individual appellants, particularly the third appellant who was an employee.
A central issue was the sufficiency of the particulars in the charges. The judge noted that there were two types of documents involved across the 12 charges: (a) specifications and (b) drawings claimed to be original works of the complainant. However, the specific documents relevant to each charge were not set out in the charges or annexures. The court considered whether this omission meant the charges were defective because the “article” alleged to have been infringed must be properly identified and correspond to the evidence at trial.
Another key issue concerned proof of distribution and the evidential reliability of the prosecution’s case. The judge accepted that distribution was not adequately proved on the record. Further, the court examined whether the prosecution’s case relied too heavily on the complainant’s oral assertions without sufficient documentary support. For the third appellant, the court also considered whether there was evidence that she was a principal or agent, or that she abetted the offences, and whether there was proof of connivance for the director appellant.
How Did the Court Analyse the Issues?
Choo Han Teck J began by addressing the structure and content of the charges. The judge observed that the prosecution’s case involved multiple charges but did not set out the specific copyrighted specifications and drawings said to be infringed. The court emphasised that the specifications alleged to be the subject of infringement must be set out in the charge and must correspond to the evidence adduced at trial. The problem was not merely that the defence did not know what documents were referred to; rather, the court found that the charges themselves lacked essential particulars, thereby undermining the fairness and clarity required in criminal proceedings.
The judge illustrated the defect using the example of the drawing admitted as P4. Counsel for the appellants argued that P4 was a 2004 document, yet it was used to prove offences allegedly committed in 2003. The judge accepted that, at the very least, the benefit of doubt should be given to the appellants where the evidence did not show that P4 originated earlier. This reasoning reflects a criminal law principle: where the prosecution’s evidence does not establish the factual basis for the alleged time period and the specific article infringed, the court cannot fill gaps in favour of the prosecution.
Turning to the drawings, the court examined the three drawings tendered in evidence. The judge found it “obvious” that the drawings were construction plans drawn up by the architects whose names appeared on the drawings. The name of Kajima was also imprinted, suggesting that the drawings might have been copies in Kajima’s possession. Importantly, nothing on the drawings indicated that the appellants knew the drawings were subject to copyright protection of the complainant or TSPL. The judge also considered the complainant’s theory of infringement: that the appellants traced over borders drawn by the complainant or TSPL. The court’s analysis suggested that the complainant’s tracing theory was problematic because it appeared the appellants were tracing over a tracing made by an unknown copier, rather than copying a protected original in a way that clearly established infringement on the evidence.
The judge further distinguished between “artistic value” and “commercial value” in the copyright sense. While the court below had accepted that drawings can have artistic value and that there is no need to mark © on a document to claim copyright protection, the High Court suggested that the lower court may have been influenced by an incorrect equivalence between commercial value and artistic value. The High Court reiterated a fundamental principle of copyright law: no claim for copyright may be made in respect of ideas and information. On the judge’s view, the specifications and drawings amounted at best to information, and the prosecution’s case did not adequately establish that what was copied fell within protectable expression rather than unprotectable ideas or information.
On distribution, the judge agreed with the appellants that distribution of the first appellant’s specifications to the alleged recipients was not adequately proved. The court noted that distribution would not have been relevant if the documents of the complainant and TSPL were not infringed; however, even on the prosecution’s own framing, the evidential basis was insufficient. This part of the reasoning underscores the importance of documentary corroboration in criminal copyright cases, especially where the prosecution’s narrative depends on what was in the appellants’ possession and what was communicated to third parties.
Finally, the court addressed individual liability. For the third appellant, the judge found there was no evidence that she was either a principal or an agent to the alleged offences, and no evidence as to how she had abetted them. The documents in question were not proved to be in her personal possession. On that ground alone, the convictions against her ought to be set aside. For the second appellant, the judge held that there was no evidence sufficient to show connivance. The mere fact that the second appellant was a director was not enough; connivance must be proved, and a company may have multiple directors none of whom are guilty unless the required mental element is established.
What Was the Outcome?
The High Court allowed the appeals and dismissed the convictions against all three appellants. The court ordered that the fines imposed at first instance be refunded. The practical effect was that the criminal liability found by the Magistrate’s Court could not stand, and the appellants were restored to their position prior to conviction.
Because the convictions were set aside on the basis of flawed charges and insufficient proof of key elements (including distribution and the mental element for individual liability), the decision also indicates that the prosecution’s case failed at foundational stages rather than merely on sentencing discretion.
Why Does This Case Matter?
Alterm Consortech is significant for practitioners because it highlights how procedural and evidential deficiencies can be fatal to criminal copyright prosecutions. The judgment underscores that charges must contain sufficient particulars identifying the specific copyrighted articles alleged to have been infringed, and those particulars must correspond to the evidence at trial. Where the prosecution’s charges are vague or mismatched with the documentary record, the court will not allow convictions to stand.
The case also provides guidance on how courts may assess infringement theories involving technical specifications and construction drawings. The High Court’s discussion of the distinction between protectable expression and unprotectable information reflects a broader copyright principle that is often overlooked in practice. Even where drawings or specifications have commercial utility, the prosecution must still show that what was copied is within the scope of copyright protection rather than merely ideas, information, or functional content.
For criminal practitioners, the decision is also a reminder that corporate and individual liability require careful proof of participation and mental element. Director status alone does not establish connivance. For employees, the prosecution must prove more than presence at the relevant time; it must show principal/agent involvement or abetment, and it must connect the individual to the relevant acts and knowledge required by the charged offences.
