Introduction

Wirral Council v Indivior PLC ([2025] EWCA Civ 40) is a landmark decision by the England and Wales Court of Appeal (Civil Division) that delves into the procedural intricacies of representative proceedings under the Civil Procedure Rules (CPR) 19.8. The case primarily questions whether representative proceedings are an appropriate mechanism for managing securities claims under sections 90 and 90A of the Financial Services and Markets Act 2000 (FSMA) in instances involving alleged fraudulent statements and omissions.

The key issues revolve around the court's discretion to allow or strike out representative proceedings in favor of multi-party actions, the interpretation of precedents such as the Supreme Court's decision in Lloyd v Google LLC [2022] AC 1217, and the practical implications for institutional and retail investors seeking redress.

Summary of the Judgment

The Court of Appeal upheld the decision of Michael Green J in the Financial List, who had struck out the representative proceedings initiated by Wirral Council against Indivior PLC. The core reasoning was that allowing the representative proceedings would hinder the Court's ability to effectively manage the case, particularly through bifurcated processes that separate common defendant-side issues from individual claimant issues such as standing, reliance, causation, and quantum.

The court emphasized that while the threshold for initiating representative proceedings under CPR 19.8(1)(a) was met, the broader discretion granted to the Court must be exercised to uphold the overriding objective of case management—ensuring that cases are dealt with justly and at a proportionate cost.

Analysis

Precedents Cited

The judgment extensively references several key cases that have shaped the current understanding of representative proceedings:

• Lloyd v Google LLC [2022] AC 1217: This Supreme Court decision underscored the potential for bifurcated representative actions, allowing for declaratory relief on common issues before addressing individual claims. However, the Court of Appeal clarified that such bifurcation should not undermine the Court's case management capabilities.
• Prudential Assurance Co Ltd v Newman Industries Ltd [1981] Ch 229: Though overturned on the substantive point, this case was pivotal in discussing the feasibility of bifurcated processes within representative actions.
• Commission Recovery Ltd v Marks & Clerk LLP [2023] EWHC 398 (Comm); [2024] 2 All ER (Comm) 949: Highlighted the limitations of bifurcated representative proceedings, especially concerning case management and follow-on claims.
• Prismall v Google UK Ltd & Ors [2023] EWHC 1169; [2024] 1 WLR 879: Demonstrated the Court's reluctance to accept representative actions that attempt to circumvent detailed individual claim assessments.
• Other significant cases include Manning & Napier v Tesco plc [2017] EWHC 3296 (Ch), Allianz Global Investors GmbH & Ors v RSA Insurance Group plc [2021] EWHC 570 (Ch), and Various Claimants v G4S Limited [2022] EWHC 1742 (Ch), all reinforcing the necessity of balanced case management in multi-party securities claims.

Legal Reasoning

The Court of Appeal focused on the discretionary power of the Court under CPR 19.8(2) and (3) to determine the appropriateness of representative proceedings. The judge in the initial hearing emphasized that, unlike in Lloyd v Google, the representative proceedings in this case sought to pre-determine issues common to all claimants without adequately addressing the essential individual issues that remain unresolved.

Key points in the legal reasoning include:

• Overriding Objective: Ensuring just and proportionate case management was paramount. The representative proceedings were seen as potentially undermining this objective by limiting the Court's ability to manage the case effectively.
• Bifurcation Concerns: The court expressed reservations about bifurcating proceedings in a manner that would sidestep essential individual claim assessments, particularly when multi-party proceedings were feasible.
• Access to Justice: While Wirral argued that representative proceedings provided necessary access to justice for retail investors, the court found insufficient evidence that multi-party proceedings were impractical or inaccessible for these claimants.
• Case Management Powers: Allowing representative proceedings would restrict the Court's ability to implement necessary case management strategies, such as ordering sample disclosures or reliance assessments.

Impact

This judgment sets a significant precedent for how representative proceedings under CPR 19.8 are treated, especially in the context of securities litigation. The key implications include:

• Reaffirmation of Case Management Discretion: Courts retain robust discretion to strike out representative proceedings if they impede effective case management and the overriding objective.
• Limitations on Bifurcated Processes: The decision underscores the court's reluctance to allow procedural mechanisms that may bypass essential individual assessments, ensuring that collective claims do not undermine the quality and fairness of litigation.
• Encouragement of Multi-party Proceedings: Parties are more likely to engage in multi-party litigation mechanisms where feasible, reinforcing the structure and rules governing securities claims under FSMA.
• Scrutiny of Representative Actions: Increased judicial scrutiny of representative proceedings to ensure they serve genuine access to justice needs rather than procedural convenience or strategic advantages.

Conclusion

The decision in Wirral Council v Indivior PLC reinforces the judiciary's commitment to maintaining robust case management processes that ensure fair and efficient resolution of claims. By upholding the strike-out of representative proceedings, the Court of Appeal has emphasized that such mechanisms must not compromise the Court's ability to oversee litigation comprehensively. This judgment serves as a crucial reference for future cases involving representative actions, particularly in the realm of securities litigation under FSMA.

Ultimately, the Court has affirmed that while representative proceedings remain a valuable tool for collective redress, they must be employed judiciously, ensuring that they align with procedural fairness and the overarching goals of the civil justice system.
