Introduction

The case of The Secretary of State for Health & Anor v Servier Laboratories Ltd & Ors ([2023] EWCA Civ 763) addressed significant issues in competition law, particularly focusing on the mitigation of damages in the context of anti-competitive conduct. The litigation involved the Servier group of companies, manufacturers of perindopril (marketed as "Coversyl"), an angiotensin-converting enzyme inhibitor used to treat cardiovascular conditions. The claimants, representing health authorities across England, Scotland, Northern Ireland, and Wales, alleged that Servier engaged in anti-competitive agreements to delay the entry of generic versions of perindopril into the UK market, thereby maintaining higher prices.

Summary of the Judgment

The Court of Appeal upheld the initial judgment dismissing Servier's defenses related to the mitigation of damages. The core of the case revolved around whether the claimants had taken all reasonable steps to mitigate their losses by encouraging the prescription of cheaper, generic alternatives to perindopril. Servier introduced the "prescribing argument," contending that the health authorities failed to adequately promote the use of more cost-effective ACE inhibitors. However, the court found that the claimants had indeed made considered and reasonable efforts to manage prescribing practices within the constraints of evolving NHS policies and priorities.

The court emphasized that the claimants' actions were not formulaic but involved evaluative judgments, taking into account various factors such as patient conditions, clinician expertise, and resource limitations. Consequently, the court rejected Servier's claims of negligence and failure to mitigate, affirming that the health authorities acted reasonably in their medicines management practices.

Analysis

Precedents Cited

The judgment referenced several key cases and legal principles to underpin its reasoning:

• Les Laboratoires Servier v Apotex Inc [2007] EWHC 1538 (Pat) and [2008] EWCA Civ 445: Established earlier that the 947 Patent related to perindopril was invalid, setting the stage for competition concerns.
• Kuwait Airways Corpn v Iraqi Airways Co (Nos 4 and 5) [2002] UKHL 19: Cited regarding the determination of loss extent, reinforcing the principle that the scope of damage claims must be just and reasonable.
• NTN Corp v Stellantis NV [2022] EWCA Civ 16: Emphasized that procedural and evidential rules should not undermine the enforcement of justiciable rights.
• Fage UK Ltd v Chobani UK Ltd [2014] EWCA Civ 5: Affirmed the finality of trial outcomes, underscoring that trials are conclusive and not mere dress rehearsals.

Legal Reasoning

The court's legal reasoning centered on the standard of "reasonable mitigation" expected of claimants in competition law damage claims. Servier attempted to argue that the health authorities should have taken more decisive steps to promote generic alternatives, thereby reducing the damages they sought. However, the court found that:

• The claimants had implemented multiple strategies to encourage cost-effective prescribing, such as formularies, the Quality and Outcomes Framework (QOF), and software tools like ScriptSwitch.
• The claimants faced competing priorities, limited resources, and evolving policies within the NHS, which justifiably influenced their medicines management decisions.
• Servier's "prescribing argument" lacked clear, formulaic criteria that could be uniformly applied across the diverse and decentralized NHS structure.
• The mitigation defense should not unduly burden the claimants with unrealistic disclosure demands or require them to standardize practices across heterogeneous health authorities.

Ultimately, the court determined that the health authorities' actions were reasonable and that Servier had not sufficiently demonstrated that the claimants failed to mitigate their losses.

Impact

This judgment reinforces the principle that in competition law, claimants must take reasonable steps to mitigate damages, but such measures must be proportionate and consider the complex realities of public healthcare administration. It clarifies that:

• Mitigation does not require uniform or formulaic actions across diverse entities.
• Reasonableness is context-dependent, factoring in resource constraints and competing priorities.
• Defenses based on alleged failure to mitigate must present clear, actionable criteria rather than vague assertions.

Future cases involving competition law and mitigation defenses will likely reference this judgment to balance the expectations placed on diverse claimants with the practicalities of their operations.

Complex Concepts Simplified

Conclusion

The Court of Appeal's decision in The Secretary of State for Health & Anor v Servier Laboratories Ltd & Ors underscores the nuanced balance courts must maintain between holding defendants accountable for anti-competitive practices and recognizing the practical limitations faced by public health authorities in mitigating damages. By rejecting Servier's broad and unfocused mitigation claims, the court affirmed that reasonable, context-sensitive actions by claimants are satisfactory, preventing undue burdens that could hinder legitimate healthcare administration. This judgment sets a clear precedent, emphasizing that mitigation defenses must be articulated with specific, actionable standards, thereby providing clarity and fairness in future competition law proceedings.
