Summary
In Guy Carpenter & Company Pte Ltd v Choi Okmi & 3 Ors ([2025] SGHC 241), the High Court considered a multi-pronged dispute arising from the alleged behind-the-scenes diversion of reinsurance broking business by two employees while they were still employed by their original employer. The claimant, a reinsurance broker, alleged that its former senior and junior brokers (the first and second defendants) acted in concert with a South Korean reinsurance broking group and its Singapore subsidiary (the third and fourth defendants) to divert business relating to “domestic warehouse risks” to the defendants’ competing entities.
The court’s analysis addressed (i) breach of confidence, including whether the information used for broking had the necessary quality of confidence and whether the defendants received it in circumstances importing an obligation of confidence; (ii) breach of contract, including contractual confidentiality obligations, duties of good faith, and post-employment restrictive covenants protecting trade connections with clients, suppliers/markets, and related non-solicitation/non-dealing restraints; and (iii) tortious claims, including inducement of breach of contract and unlawful means conspiracy. The judgment also dealt with a procedural evidential issue concerning cross-examination of a witness called by a co-defendant.
What Were the Facts of This Case?
The claimant, Guy Carpenter & Company Pte Ltd (“Claimant”), is a reinsurance broker. Its business involves brokering reinsurance contracts between insurance or reinsurance customers (who seek to reinsure risks for their own clients) and reinsurers/markets (who provide reinsurance). The court described two main categories of reinsurance broking: facultative reinsurance (in respect of specific policies or defined packages of risks, requiring re-evaluation of each risk) and treaty reinsurance (covering risks within a pre-defined book or class of business, reducing the need for re-evaluation of each individual risk).
The third defendant, LK Insurance Services Co Ltd (“Third Defendant”), is a South Korean reinsurance broking company. The fourth defendant, LK Re Pte Ltd (“Fourth Defendant”), is its Singapore subsidiary incorporated on 8 April 2021. The Fourth Defendant obtained a general reinsurance broker licence from the Monetary Authority of Singapore (MAS) on 3 November 2021. Both the Claimant and the LK group operate in the same reinsurance broking market, making the dispute one of direct commercial competition.
The first defendant, Ms Choi Okmi (also known as Celeste) (“First Defendant”), was a former Senior Vice-President of the Claimant. She joined on 1 July 2018 and her role primarily involved facultative reinsurance business under the Korean desk. She tendered resignation on 15 November 2021 and, due to a six-month notice period, her employment ended on 14 May 2022. She entered into an employment contract with the Fourth Defendant on 19 November 2021, agreeing to commence employment as Chief Broking Officer on 16 May 2022. A central factual dispute was whether she began substantive work for the Fourth Defendant before her formal departure date, with the Claimant alleging earlier involvement and the First Defendant maintaining that she only began work on the contractual start date.
The second defendant, Mr Lee Dong Yeol (also known as Dominic) (“Second Defendant”), was a former junior broker at the Claimant’s facultative reinsurance broking department. He commenced employment on 1 November 2018 and the First Defendant was his direct supervisor. The record emphasised a close mentor-mentee relationship and prior acquaintance. Like the First Defendant, the Second Defendant later ended up working for the Fourth Defendant. The court’s findings turned on whether the two defendants, while still employed by the Claimant, had coordinated with the LK entities to divert business—particularly business connected to “domestic warehouse risks”—and whether such coordination involved misuse of confidential information and breach of contractual duties and restrictive covenants.
What Were the Key Legal Issues?
First, the court had to determine whether the Claimant established a breach of confidence. This required the Claimant to show that the information allegedly used for broking had the necessary “quality of confidence” and that it was received in circumstances importing an obligation of confidence. The court also had to consider whether the defendants’ state of mind and conduct meant that their “conscience” was affected—an essential element in equitable breach of confidence claims.
Second, the court addressed contractual and employment-law issues. These included whether the First and Second Defendants breached contractual confidentiality obligations and duties of good faith during their employment, and whether they breached post-employment restrictive covenants. The restrictive covenants in issue protected the Claimant’s trade connections, including non-solicitation and non-dealing restraints relating to clients and “markets” (as the court framed it in the reinsurance broking context). The court also considered whether the restraints were reasonable and in the public interest.
Third, the court considered tortious claims, including inducement of breach of contract and unlawful means conspiracy. These issues required findings on whether the defendants combined to carry out acts in furtherance of competing with the Claimant’s domestic warehouse risks business, whether the acts were “unlawful” for conspiracy purposes, and whether the Claimant suffered loss as a result. Finally, there was a procedural evidential issue: the court considered the propriety and scope of cross-examination of a witness called by a co-defendant, which can affect how evidence is tested and weighed.
How Did the Court Analyse the Issues?
The court’s approach to breach of confidence was structured around established equitable principles. It examined whether the information provided for broking purposes had the necessary quality of confidence. In commercial brokerage contexts, not all information is automatically confidential; the court looked for the nature of the information, its relevance to the Claimant’s business, and whether it was the kind of information that would reasonably be treated as confidential within the industry and within the parties’ relationship. The judgment also addressed whether the information was received in circumstances importing an obligation of confidence. This involved scrutinising the circumstances in which the defendants obtained or used the information, including whether there was a legitimate basis to treat it as confidential and whether the defendants’ conduct indicated an awareness of confidentiality obligations.
On the “conscience” element, the court focused on whether the First Defendant failed to prove that her conscience was unaffected. In practical terms, this meant the court evaluated competing narratives about when and how the First Defendant began working for the Fourth Defendant, and whether she had acted in a manner inconsistent with her obligations to the Claimant. The court’s reasoning suggests that it was not enough for the defendants to assert that they were merely responding to client choice; rather, the court examined whether the defendants orchestrated transitions and business diversion in a way that exploited trust, goodwill, and proprietary knowledge acquired through employment.
The court’s factual findings were supported by what it described as key pieces of evidence. The judgment references, among other matters, a virtual meeting between the First Defendant and representatives of the Third Defendant; evidence about the Second Defendant’s actual employment arrangements between 15 November 2021 and 31 March 2022; and documentary and email-based evidence, including the use of the Fourth Defendant’s email signature, reference letters, and broker-of-record communications. The court also considered an SFMI Excel file forwarded by the Second Defendant to the First Defendant, and communications involving Tokio Marine and a draft MOM appeal letter. These materials were used to assess whether the defendants’ conduct was consistent with lawful competition or instead indicated coordinated diversion and concealment.
In addition, the court addressed evidence that it considered to have limited probative value or that it gave little weight. The judgment mentions evidence of Mr Noe from SFMI, evidence of Mr Kim from the Fourth Defendant, and evidence of Ms Mah. This indicates that the court did not treat all evidence as equally reliable or persuasive, and it evaluated credibility and relevance in light of the overall narrative and documentary record. The evidential analysis was particularly important because the dispute involved competing accounts of timing and the extent of involvement during the notice period.
Turning to breach of contract, the court analysed multiple layers of contractual wrongdoing. It considered whether the First and Second Defendants breached duties of good faith and contractual confidentiality obligations. It also examined whether they breached contractual terms prohibiting secondary business or employment, and whether they breached the Claimant’s compliance policies. The court then assessed post-employment restrictive covenants, which were central to the employment-law dimension of the case.
For restrictive covenants protecting trade connections with clients, the court applied a reasonableness framework. It found that the Claimant had a legitimate interest in protecting its trade connection with its clients. It then considered whether the non-solicitation and non-dealing covenants were reasonable between the parties and whether they were in the public interest. The court’s reasoning indicates that it treated the reinsurance broking relationship as one where client connections and broker goodwill are valuable and where departing employees may be tempted to exploit knowledge gained during employment. On the evidence, the court concluded that the First and Second Defendants breached the non-solicitation and non-dealing covenants.
The court similarly analysed restrictive covenants protecting trade connections with “markets”. It again found a legitimate interest in protecting those connections and assessed the reasonableness of the non-enticing covenant. The court concluded that the covenant was reasonable in the interests of the parties and in the public interest, and that the First and Second Defendants breached it. This part of the judgment is likely to be of particular interest to practitioners because it demonstrates how restrictive covenants can be tailored to the specific commercial realities of brokerage and market relationships.
On inducement of breach of contract and unlawful means conspiracy, the court examined whether the defendants combined to carry out acts in furtherance of competing with the Claimant’s domestic warehouse risks business. The court’s reasoning indicates that it inferred intention to cause damage or injury from the pattern of conduct, including coordination while still employed and the use of mechanisms that suggested circumvention. For conspiracy, the court required that the acts were “unlawful” and that the Claimant suffered loss as a result. The judgment’s structure suggests that it treated the unlawful means as arising from the breach of contractual obligations and/or breach of confidence, which then supported the conspiracy and inducement claims.
Finally, the procedural issue concerning cross-examination of a witness called by a co-defendant reflects the court’s attention to fairness in the adversarial process. Where a witness is called by one party, the scope and manner of cross-examination by another party can raise questions about how evidence is tested. The judgment’s inclusion of this issue indicates that the court considered whether the cross-examination was properly conducted and how it should affect the weight given to the witness’s evidence.
What Was the Outcome?
Based on the court’s findings across breach of confidence, breach of contract, and tortious claims, the Claimant succeeded in establishing liability against the relevant defendants for the diversion and misuse of business connected to domestic warehouse risks, including breaches of confidentiality and restrictive covenants. The practical effect is that the judgment confirms that employees in regulated, relationship-driven brokerage industries cannot rely on formal client choice to justify coordinated circumvention of contractual restraints and obligations.
The judgment also addressed the counterclaim brought by the Third Defendant against the Claimant. While the extract provided does not include the final dispositive orders, the overall structure and conclusion indicate that the court’s findings on the main claims were substantial and that the counterclaim was considered in light of the same factual matrix and evidential record.
Why Does This Case Matter?
This decision is significant for employment and commercial litigation practitioners in Singapore because it illustrates how courts evaluate restrictive covenants and confidentiality obligations in a brokerage context where “trade connections” are central. The court’s reasoning on legitimate interest, reasonableness, and public interest provides a useful template for drafting and enforcing non-solicitation, non-dealing, and non-enticing restraints tailored to client and market relationships.
It also matters for breach of confidence claims in commercial settings. The judgment demonstrates that courts will scrutinise not only whether information was confidential in nature, but also the circumstances of receipt and the affected “conscience” of the defendant. Where evidence shows coordination during employment and documentary/email conduct consistent with concealment or premature transition, courts are likely to infer breach and reject narratives that frame the conduct as mere competition.
From a tort perspective, the case is also instructive on unlawful means conspiracy and inducement of breach of contract. The court’s willingness to treat contractual and equitable breaches as unlawful means underscores the importance of understanding how employment-related wrongdoing can escalate into tortious liability, particularly where multiple actors coordinate to achieve competitive advantage.
