Introduction

The legal landscape governing non-compete undertakings among law firms has been significantly shaped by the landmark decision in Harcus Sinclair LLP & Anor v. Your Lawyers Ltd ([2021] UKSC 32). This case delves into the enforceability of non-compete clauses between incorporated law firms within the context of group litigation concerning the Volkswagen diesel emissions scandal. The Supreme Court's judgment addresses critical issues surrounding the nature of solicitor's undertakings, the scope of the court's supervisory jurisdiction over incorporated law firms, and the balance between contractual obligations and public policy in the realm of restraint of trade.

Summary of the Judgment

In this case, Your Lawyers Ltd sought to enforce a non-compete undertaking against Harcus Sinclair LLP, alleging that Harcus Sinclair breached an agreement that prevented it from acting for group claimants in the Volkswagen emissions litigation without explicit permission. The High Court initially upheld the non-compete clause, deeming it reasonable and not an unreasonable restraint of trade. However, the Court of Appeal overturned this decision, declaring the non-compete undertaking unenforceable. Upon reaching the Supreme Court, the central issues were reassessed, culminating in the decision that the non-compete undertaking was not a solicitor's undertaking and thus not subject to the court's supervisory jurisdiction. Furthermore, even if it were considered a solicitor's undertaking, it would still be unenforceable due to its nature as an unreasonable restraint of trade.

The judgment extensively references pivotal cases that have shaped the doctrine of restraint of trade and the nature of solicitor's undertakings. Notable among these are:

• Assaubayev v Michael Wilson & Partners Ltd ([2014] EWCA Civ 1491)

These cases collectively examine the boundaries of reasonable restraints in trade and the specific characteristics that constitute a solicitor's undertaking. The Supreme Court's engagement with these precedents underscores the evolving nature of legal services provision and the necessity to adapt traditional doctrines to contemporary corporate structures like LLPs.

Legal Reasoning

The Supreme Court's legal reasoning addresses two primary questions: whether the non-compete clause constitutes a solicitor's undertaking, and whether such a clause is an unreasonable restraint of trade. The Court concluded that the non-compete undertaking was not a solicitor's undertaking because it was given by an incorporated entity acting in a business capacity, rather than in a professional capacity as an officer of the court. This distinction is crucial as solicitor's undertakings are subject to the court's supervisory jurisdiction due to their professional nature.

Furthermore, the Court affirmed that even if the undertaking were considered a solicitor's undertaking, it would still be unenforceable as it exceeded what was reasonably necessary to protect Your Lawyers' legitimate interests. The six-year duration of the non-compete was deemed disproportionate, thereby categorizing it as an unreasonable restraint of trade.

Impact

The Supreme Court's decision has profound implications for the legal profession, particularly for incorporated law firms operating as LLPs or limited companies. It clarifies that non-compete clauses between such entities are not inherently solicitor's undertakings and are subject to standard contractual scrutiny under the restraint of trade doctrine. This ruling necessitates that law firms exercise caution when drafting non-compete clauses, ensuring that such restrictions are reasonable, proportionate, and clearly justified by legitimate business interests.

Additionally, the judgment highlights a gap in the current legal framework regarding the enforcement of undertakings by incorporated law firms, signaling a potential area for legislative intervention to provide clearer guidelines and protections analogous to those enjoyed by traditional, unincorporated solicitors.

Conclusion

The Supreme Court's decision in Harcus Sinclair LLP v Your Lawyers Ltd serves as a pivotal reference point for the enforceability of non-compete undertakings within the modern, corporate-structured legal profession. By delineating the boundaries of solicitor's undertakings and affirming the application of the restraint of trade doctrine to incorporated law firms, the judgment fosters a more nuanced understanding of contractual limitations and professional responsibilities. Law firms must reevaluate their contractual practices to align with these clarified legal standards, ensuring that any restrictive clauses are meticulously justified and proportionate to their legitimate business interests.

Moreover, the case underscores the need for legislative consideration to address emerging complexities arising from corporate law firm structures, ensuring that the supervisory mechanisms remain robust and adaptable to evolving professional landscapes.
