Summary
Smile Inc Dental Surgeons Pte Ltd v Lui Andrew Stewart [2012] SGCA 39 concerns an employer’s attempt to enforce restrictive covenants against a former associate dentist and to claim that the employee breached implied duties of good faith and fidelity, as well as fiduciary obligations. The Court of Appeal upheld the High Court’s dismissal of the employer’s action, agreeing that the restrictive covenants were void for unreasonable restraint of trade and that, on the facts, the employee did not breach his duty of fidelity. The Court also affirmed that the employee did not owe fiduciary duties to the employer in the circumstances.
Although the High Court found breaches of certain contractual restrictions (notably the “Radial Clause” and “Non-Dealing Clause”), the Court of Appeal agreed that the covenants were unenforceable because they were unreasonable, in particular due to their unlimited duration. The Court further clarified the scope of acceptable conduct by employees who engage in preparatory steps to compete while still employed, and it emphasised the importance of pleading and evidential discipline when attempting to rely on additional factual allegations.
What Were the Facts of This Case?
The respondent, Dr Andrew Stewart Lui, was employed by Smile Inc Dental Surgeons Pte Ltd as an associate dental surgeon. He was assigned full-time work at the appellant’s clinic at Forum the Shopping Mall (the “Forum Clinic”) with effect from July 2005. The employment relationship was governed by an Employment Contract containing restrictive covenants in clauses 23 to 25. These clauses addressed (i) non-solicitation of patients and non-damage to reputation, (ii) a geographical restriction on practice after leaving, and (iii) a non-dealing/non-removal regime concerning corporate and non-corporate contracts, patients, patient data and records, office data and records, and computer software programmes and data.
At the Forum Clinic, the respondent and another dentist, Dr Gareth Pearson, accounted for approximately 80% of the clinic’s patient pool. In March 2008, Dr Pearson gave notice that he intended to stop working for the appellant in September 2008. This context mattered because it suggested that the clinic’s revenue and patient base were closely tied to the dentists’ personal practice and relationships.
In January 2009, while still employed, the respondent incorporated a company, Dental Essence Pte Ltd (“Dental Essence”). Shortly thereafter, he entered into a tenancy agreement for premises within a five-minute walk from the Forum Clinic. On the same day, he gave written notice of resignation to the appellant. In March 2009, he committed to renovation works for Dental Essence’s premises, and Dr Pearson joined Dental Essence as a shareholder and dentist. The appellant agreed that the respondent’s last day of work would be 18 April 2009.
After the respondent’s departure, the Forum Clinic experienced a significant decrease in monthly revenue. The appellant also received requests from numerous patients for their dental records and later discovered that many of those patients had become patients of Dental Essence. The appellant commenced an action against the respondent on 8 October 2009 and subsequently closed the Forum Clinic in September 2010. The appellant’s case was therefore both contractual (breach of restrictive covenants) and employment-law based (breach of implied duty of good faith and fidelity, and an alternative claim that fiduciary duties were owed).
What Were the Key Legal Issues?
The Court of Appeal identified four crucial issues. First, it had to determine whether the restrictive covenants were in unreasonable restraint of trade and therefore void and unenforceable. This required the court to consider whether the covenants protected legitimate proprietary interests and whether they were reasonable both as between the parties and in the interests of the public.
Second, the Court had to decide whether the restrictive covenants could be read down to impose a time limitation, thereby making them reasonable and enforceable. This issue is significant in Singapore restraint-of-trade jurisprudence because courts sometimes consider whether severance or reading down is appropriate, particularly where the covenant is broader than necessary.
Third, the Court had to consider whether the respondent, as an associate dentist, owed fiduciary duties to the appellant. This issue turned on the nature of the employment relationship and whether the respondent occupied a position of trust and confidence such that fiduciary obligations arose.
Fourth, the Court had to assess whether the respondent’s actions—specifically, forming a competing business while still employed—breached his duty of good faith and fidelity. This required the Court to delineate the boundary between permissible preparatory conduct and impermissible conduct that undermines the employer’s interests during the employment period.
How Did the Court Analyse the Issues?
1. Non-solicitation and pleading/evidence discipline
The Court of Appeal first addressed the Non-Solicitation Clause (clause 23). The High Court had found no evidence of solicitation by the respondent. On appeal, the parties did not contest the High Court’s findings that the respondent breached the Radial Clause and the Non-Dealing Clause. The dispute therefore focused on whether there was sufficient evidence of solicitation to establish a breach of the Non-Solicitation Clause.
The appellant attempted to rely on two categories of evidence: (i) that the respondent purchased online advertisements (“Google Ad Words” and “Yahoo”) using keywords such as “forum dentist” and similar phrases, and (ii) a testimonial by a person, Carolyn Strover, published in an August 2009 issue of a magazine (“Expat Living”). However, the Court of Appeal agreed with the High Court that these material facts were not pleaded in the Statement of Claim. As a result, even if they could have been made out, they could not be admitted as evidence for the purpose of establishing solicitation. This illustrates a procedural point with substantive consequences: in civil litigation, the scope of evidence is constrained by the pleadings, and parties cannot generally “fill gaps” in their pleaded case through unpleaded factual allegations.
The Court further held that the appellant’s remaining evidence—namely that Dental Essence had a similar price list and that many patients requested their dental records and then became Dental Essence patients—was insufficient, even if unrebutted, to establish solicitation by the respondent. The Court’s approach reflects the evidential burden on the party alleging solicitation: correlation between the employer’s decline and the employee’s new practice does not automatically prove active solicitation.
2. Restraint of trade: legitimate proprietary interests and reasonableness
On the enforceability of the restrictive covenants, the Court of Appeal reaffirmed the established test. It cited Man Financial (S) Pte Ltd v Wong Bark Chuan David [2008] 1 SLR(R) 663 and CLAAS Medical Centre Pte Ltd v Ng Boon Ching [2010] 2 SLR 386, explaining that the court first asks whether there is a legitimate proprietary interest to be protected beyond merely preventing competition. If such an interest exists, the court applies the twin reasonableness tests associated with Lord Macnaghten’s formulation in Nordenfelt (Pauper) v The Maxim Nordenfelt Guns and Ammunition Company, Limited [1894] AC 535: (i) reasonableness as between the interests of the parties, and (ii) reasonableness as between the interests of the public. The Court also emphasised that enforcement should not go further than necessary to protect the legitimate proprietary interest(s).
Importantly, the Court noted that a stricter approach applies in employment contracts. This is because restraints of trade in employment directly affect an individual’s ability to earn a living. In that context, the employer must justify why the restriction is necessary and appropriately limited. The Court of Appeal agreed with the High Court that the restrictive covenants were in unreasonable restraint of trade and were therefore void and unenforceable.
The key reason, as accepted by the Court of Appeal, was that the covenants were unlimited in duration. Even though the High Court found breaches of the Radial and Non-Dealing Clauses, the enforceability of those clauses depended on whether they were reasonable. Unlimited duration meant the covenants went beyond what was necessary to protect legitimate interests, and thus failed the reasonableness inquiry.
3. Reading down and severance
One of the issues on appeal was whether the restrictive covenants could be read down to include a time limitation. The Court of Appeal accepted the High Court’s conclusion that the covenants were void and unenforceable. While the extract provided does not reproduce the full reasoning on reading down, the outcome indicates that the Court was not prepared to rewrite the parties’ bargain by imposing a duration that the contract itself did not specify. In restraint-of-trade cases, reading down is not automatic; it depends on whether the court can do so without effectively creating a new contract or altering the parties’ allocation of risk and protection.
Practically, this reinforces a drafting lesson for employers: if a restriction is intended to be enforceable, it should be tailored with a clear and reasonable temporal scope. Courts may be willing to sever or adjust where the covenant is capable of being made reasonable, but where the covenant is fundamentally overbroad—such as being unlimited in duration—the court may treat it as beyond salvage.
4. Fiduciary duties and the duty of good faith and fidelity
The Court of Appeal also upheld the High Court’s findings that the respondent did not owe fiduciary duties to the appellant. Fiduciary duties arise only in specific relationships and circumstances where the employee is in a position of trust and confidence and where the law recognises that duties of loyalty beyond contractual obligations are owed. The Court accepted that, on the facts, the employment relationship did not give rise to fiduciary obligations.
On the duty of good faith and fidelity, the Court agreed with the High Court that, on the facts, the respondent did not breach that duty. This part of the decision is particularly relevant to employment disputes involving competition. The Court considered the ambit of acceptable conduct by employees who engage in preparatory activities to compete while still employed. The respondent’s conduct included incorporating a competing company, securing premises nearby, and arranging renovations, while still employed. The Court’s acceptance that there was no breach of fidelity indicates that preparatory steps—without more—may fall within permissible conduct, provided they do not involve solicitation, misuse of confidential information, or active undermining of the employer’s business during the employment period.
In other words, the Court drew a line between (i) lawful preparation to compete and (ii) conduct that breaches loyalty obligations. The absence of evidence of solicitation, together with the procedural limitations on unpleaded evidence, likely played a role in the Court’s conclusion that the duty of fidelity was not breached.
What Was the Outcome?
The Court of Appeal dismissed the appeal. It agreed with the High Court that the Non-Solicitation Clause was not breached, and it accepted the High Court’s findings that the restrictive covenants were void and unenforceable due to unreasonable restraint of trade, particularly because they were unlimited in duration.
It also affirmed that the respondent did not owe fiduciary duties to the appellant and that, on the facts, there was no breach of the duty of good faith and fidelity. The practical effect is that the employer could not obtain relief based on the restrictive covenants or on implied loyalty-based duties, despite evidence that the respondent’s post-employment activities fell within the geographical and non-dealing restrictions.
Why Does This Case Matter?
Smile Inc Dental Surgeons Pte Ltd v Lui Andrew Stewart is a useful authority on restraint of trade in employment contracts, especially where covenants are drafted without a clear temporal limit. The decision underscores that even if an employer can show that an employee’s conduct falls within the literal wording of a restrictive covenant, the covenant may still be unenforceable if it is unreasonable. Unlimited duration is a recurring red flag in employment restraints, and this case confirms that courts will not readily enforce such provisions.
The case also clarifies the evidential and pleading requirements in civil litigation. The Court’s refusal to admit unpleaded factual allegations about online advertising and a magazine testimonial demonstrates that litigants must plead material facts precisely and cannot rely on later “add-ons” to establish breach. For practitioners, this is a reminder that restraint-of-trade claims often depend on granular factual proof (eg, solicitation, misuse of records, or active canvassing), and those facts must be properly pleaded and supported by admissible evidence.
Finally, the decision is significant for employment-law loyalty analysis. It illustrates that employees may undertake preparatory steps to compete while still employed, and that not every competitive move is automatically a breach of good faith and fidelity. The boundary will depend on the nature of the conduct, the presence or absence of solicitation, and whether confidential information or trust-based obligations are abused. This makes the case particularly relevant for employers and employees in professional services settings, where personal relationships and client migration are common.
