Summary
Smile Inc Dental Surgeons Pte Ltd sued its former employee, Dr Andrew Stewart Lui, alleging breaches of both express and implied terms of his employment contract. The dispute arose after Dr Lui resigned from Smile and set up a competing dental practice through a company he incorporated, Dental Essence Pte Ltd. Smile contended that Dr Lui’s post-employment activities breached restrictive covenants in the contract (including a “radial” non-practice restriction) and also involved improper use of Smile’s patient base and patient records.
After the close of Smile’s case, Dr Lui elected to make a submission of no case to answer and did not adduce evidence. Woo Bih Li J dismissed Smile’s action with costs to be paid to Dr Lui. The court’s reasoning, as reflected in the judgment extract, turned on whether Smile had proved the contractual breaches it alleged—particularly given the absence of Dr Lui’s evidence and the evidential gaps concerning timing, patient migration, and the scope and enforceability of the contractual restrictions.
What Were the Facts of This Case?
Smile was incorporated in Singapore in March 1997 by Dr Ernest Rex Tan Sek Ho (“Dr Tan”) and his wife, Ms Chong Mo-Ai Grace. Dr Tan and Ms Chong were equal shareholders and the only directors. Dr Tan is a practising dentist and specialist prosthodontist certified by the Singapore Dental Council, while Ms Chong is not a practising dentist but serves as Managing Director of Smile.
Smile opened its first clinic, the Suntec Clinic, in October 1997, and its second clinic, the Forum Clinic, in September 1998 at Forum the Shopping Mall. The Forum Clinic was positioned as a children and family-themed dental practice, consistent with the mall’s branding. Dr Tan described the Forum Clinic’s clientele as largely locals, expatriates, and tourists from upper middle to high income families frequenting the Orchard and Tanglin area. A third clinic, the ORQ Clinic, was set up in 2005.
Dr Lui, an Australian citizen, approached Smile in 2003 to explore employment. He was dissatisfied with his then associate dentist employment at a practice in Great World City, where his remuneration depended on patient numbers and he felt the practice lacked sufficient “profile and visibility.” Dr Tan and Ms Chong were impressed by Dr Lui’s personality, skills, and chair-side manners, and they discussed employment prospects with him. Dr Lui held an Employment Pass and indicated that he planned to return to Melbourne to look after his mother, and he did not intend to apply for Permanent Resident status.
The employment contract was signed on 31 July 2003. The contract provided that Dr Lui would be an “associate dental surgeon” remunerated at 40% of the net professional fees collected each month. Although an initial draft stipulated a five-year minimum term, Dr Lui negotiated this down to three years. Smile’s witnesses believed it was “completely inconceivable” that Dr Lui would seek to practise elsewhere in Singapore after his employment ended, given his stated intention to return to Australia. Dr Lui began work on 1 September 2003 and initially practised at both the Suntec and Forum Clinics; from July 2005 he was assigned full-time to the Forum Clinic.
Smile invested heavily in advertising and marketing, particularly after the Ministry of Health relaxed advertising guidelines for medical and dental professions around end-2004. It erected a large light box signage at the Forum mall facade and ran promotional features in family magazines that included dentists at the Forum Clinic, including Dr Lui. This marketing effort was aimed at increasing the brand profile and the profile of individual dentists.
On 7 January 2009, while still employed by Smile, Dr Lui incorporated Dental Essence Pte Ltd, of which he was the sole director and shareholder. On or about 25 February 2009, he entered into a one-year tenancy for premises at Tudor Court, located within five minutes’ walk from the Forum Clinic. On the same day, he gave written notice of resignation to Smile. Although the contract required three months’ notice, Smile agreed that his last day would be 18 April 2009. Dental Essence obtained a licence from the MOH on 14 May 2009 and began operations on 15 May 2009.
Smile alleged that Dr Lui committed in March 2009 to renovation works for Dental Essence’s premises of about $60,000. Dr Gareth Pearson, a former Smile employee, joined Dental Essence as a shareholder and dentist on 19 March 2009. Dr Pearson had previously given Smile six months’ notice in March 2008 that he would stop working in September 2008 for an indefinite period due to leaving Singapore. Dr Lui and Dr Pearson together accounted for about 80% of the Forum Clinic’s patient pool.
After Dr Lui left, Smile’s Forum Clinic revenue declined sharply. Dr Tan stated that monthly revenue was about $116,000 in April 2009 (the month Dr Lui left) but dropped to about $52,000 by September 2009, a decline of roughly 55%. Smile commenced the action on 8 October 2009. It later received requests from patients for their dental records and discovered that many became patients of Dental Essence. The Forum Clinic’s revenue continued to dwindle, and Smile eventually closed the Forum Clinic on 15 September 2010, coinciding with the expiry of the clinic licence.
In January 2011, the case was bifurcated upon Dr Lui’s application. The trial proceeded on the reduced issues agreed by the parties. Only two witnesses for Smile gave evidence: Dr Tan and his wife Ms Chong. Dr Lui elected to make a submission of no case to answer after Smile’s case closed and did not adduce evidence.
What Were the Key Legal Issues?
The first key issue was whether Dr Lui breached express contractual provisions. Smile relied on two broad categories of causes of action. The first concerned express restrictions in the contract that allegedly prevented Dr Lui from undertaking certain activities after leaving Smile. In particular, Smile pleaded that Dr Lui breached Clause 24 (the “Radial Clause”) by practising within a three-kilometre radius of Smile’s Suntec and Forum practices and within a three-kilometre radius of any other new Smile practices set up before and during his cessation of work.
The second express-breach allegation concerned Clauses 23 and/or 25. Smile alleged that Dr Lui, after leaving, conducted consultations, examinations, and/or treatment of Smile’s patients, and that he canvassed, solicited, or procured Smile’s patients for himself or others. Smile also alleged that patient data and records remained Smile’s property and that Dr Lui’s conduct involved improper handling or use of that information. The pleaded case included an allegation that, after discovery, Smile found 716 patients of Dental Essence who had been treated by Dr Lui on at least one occasion while he was employed by Smile, though it was not clear when all those patients migrated to Dental Essence.
The second key issue was whether Dr Lui breached implied terms of the employment contract. Smile pleaded that implied duties existed requiring Dr Lui to act in good faith and not to harm Smile’s business or reputation, and that his post-employment conduct breached those implied obligations. The court had to consider whether the evidence adduced by Smile was sufficient to establish these breaches to the required standard, especially in the context of a submission of no case to answer.
How Did the Court Analyse the Issues?
At the outset, the court framed the dispute as one about contractual obligations arising from an employment relationship, and it proceeded on the basis that Smile bore the burden of proving its pleaded breaches. The procedural posture was significant: after Smile closed its case, Dr Lui made a submission of no case to answer. In such circumstances, the court must consider whether the evidence led by the plaintiff, taken at its highest, could support the pleaded causes of action. If the evidence is insufficient to establish the essential elements of the claim, the action must fail without requiring the defendant to call evidence.
On the Radial Clause, the court had to determine whether Smile proved that Dr Lui practised within the prohibited radius and whether the clause operated without a time limit in a way that was enforceable and applicable to the facts. The clause, as pleaded, imposed a restriction “in the event that Dr. Lui leaves (whether resignation or dismissal)” and prohibited him from practising within a three-kilometre radius distance from Smile’s Suntec and Forum practices, and from any other new Smile practices set up before and during his cessation of work. The absence of a time limit meant that the clause was not merely a short-term restraint; it was potentially a continuing restriction. The court therefore required clear evidence that the factual preconditions for the clause were met and that the conduct complained of fell within its scope.
Smile’s evidence, as reflected in the extract, focused on the location of Dental Essence’s premises at Tudor Court and the proximity of that location to the Forum Clinic. However, the Radial Clause also referenced Suntec City and “any other new Smile” practices set up before and during Dr Lui’s cessation of work. The court would have needed to consider the geography of all relevant Smile practices and whether Smile proved the radius distances with sufficient precision. In addition, because Dr Lui did not adduce evidence, the court had to rely entirely on Smile’s evidence to establish that Dr Lui’s post-employment practice was within the prohibited radius and that the clause was triggered by the relevant “leaving” event.
On the patient-related clauses, the court had to assess whether Smile proved that Dr Lui breached Clauses 23 and/or 25 by soliciting or procuring Smile’s patients, or by treating them in a manner that constituted a contractual breach. Smile’s evidence included the fact that Dental Essence treated 716 patients who had been treated by Dr Lui while he was employed by Smile. Yet the court would have been alert to the evidential gap identified in the extract: it was “not clear when all the 716 patients eventually migrated to Dental Essence.” That uncertainty matters because the contractual allegations were about post-employment conduct. If Smile could not establish that the relevant patients were solicited or procured after Dr Lui left, or that Dr Lui’s treatment of those patients was connected to a breach of the restrictive covenant, then the evidence might not satisfy the essential elements of the claim.
Further, Smile alleged that Dr Lui conducted consultations, examinations, and/or treatment of Smile’s patients after he left. While the existence of overlapping patient lists suggests a possible connection, the court would still require proof of the contractual wrong—namely, canvassing, soliciting, procuring, or damaging Smile’s reputation, and/or improper handling of patient data and records. The extract indicates that Smile discovered that many patients became patients of Dental Essence after it received requests for dental records. That discovery supports a correlation between Dr Lui’s departure and patient migration, but correlation alone does not necessarily prove solicitation or breach of the specific contractual duties.
In analysing implied terms, the court would have considered the limits of implying duties into employment contracts, particularly where the contract already contains express restrictions. Courts generally avoid using implied terms to expand obligations beyond what is necessary, especially where the parties have negotiated detailed express provisions. Thus, the implied-duty analysis likely depended on whether the same factual matrix that allegedly constituted express breaches also established a breach of implied obligations such as fidelity, good faith, or non-competition in substance. If Smile’s evidence was insufficient to prove the express breaches, it would be difficult to sustain implied breaches on the same evidential foundation.
Finally, the court’s dismissal at the no case stage suggests that Smile’s evidence, even taken at its highest, did not establish the pleaded breaches to the requisite standard. The court’s reasoning therefore reflects a disciplined approach to contractual proof: a plaintiff cannot rely solely on post-employment business decline, proximity of the new practice, or overlapping patient lists without demonstrating the contractual elements—particularly the causal link to solicitation/procurement and the factual scope of the restrictive covenant.
What Was the Outcome?
Woo Bih Li J dismissed Smile’s action and ordered costs to be paid to Dr Lui. The practical effect was that Smile failed to obtain damages or other relief for the alleged contractual breaches, and Dr Lui was not required to answer the claim on the merits beyond the submission of no case to answer.
Smile subsequently appealed to the Court of Appeal, but the appeal was dismissed on 31 July 2012 (Civil Appeal No 145 of 2011), as noted in the LawNet editorial note.
Why Does This Case Matter?
This decision is significant for employment and restrictive covenant disputes in Singapore because it illustrates the evidential burden on an employer seeking to enforce post-employment contractual restrictions. Even where an employer can show business decline after an employee’s departure and can identify overlapping patients, the employer must still prove the specific contractual breaches pleaded—such as whether the employee practised within the prohibited radius and whether the employee canvassed, solicited, or procured patients in breach of the contract.
The case also demonstrates the importance of precision in pleading and proof. Where a restrictive covenant is drafted broadly (for example, with no time limit) and where patient migration is central to the claim, the employer must marshal evidence that addresses timing and causation. The court’s willingness to dismiss at the no case stage underscores that a plaintiff cannot proceed on inference alone when the essential elements remain unproven.
For practitioners, the case is a useful reminder to (i) ensure that restrictive covenants are supported by clear factual evidence, (ii) consider whether patient record requests and overlapping patient lists can establish solicitation or procurement, and (iii) anticipate how courts will treat evidential gaps—particularly when the defendant does not call evidence and the plaintiff’s case must stand on its own.
