Introduction

The case of BT Group Plc v Patourel ([2022] EWCA Civ 593) presents a significant examination of the discretion exercised by the Competition Appeal Tribunal (CAT) in certifying collective proceedings. At the heart of the dispute lies the choice between opt-in and opt-out mechanisms for class actions, particularly in the context of alleged abuse of dominant market position under the Competition Act 1998 (CA 1998). BT Group Plc, alongside British Telecommunications Plc, contested the CAT's decision to certify a claim for damages as eligible for collective (class) proceedings on an opt-out basis, which would automatically include approximately 2.3 million individuals unless they chose to exclude themselves.

Summary of the Judgment

The Competition Appeal Tribunal had certified a collective claim against BT Group Plc, alleging that the company abused its dominant position in the voice-only telephony market by imposing supra-competitive prices, violating section 18 of the CA 1998. The CAT opted for an opt-out basis, facilitating access to justice for a vast number of consumers without necessitating their active participation. BT argued that an opt-in mechanism, requiring individuals to actively join the proceedings, would have been more appropriate. However, the Court of Appeal upheld the CAT's decision, affirming its discretion to choose the opt-out route based on factors like the practicality of securing participation and the role of third-party funders.

Analysis

Precedents Cited

The judgment heavily referenced two pivotal Supreme Court cases: Mastercard v Merricks [2020] UKSC 51 and Lloyd v Google Inc [2021] UKSC 50.

• Merricks: This case delved into the certification process, emphasizing the purpose behind the collective action regime—facilitating access to justice and deterring anti-competitive behavior through mass consumer claims. The Supreme Court underscored the importance of not being overly restrictive in interpreting the certification criteria, advocating for a balance between judicial economy and compensatory justice.
• Lloyd: Focused on the scope of third-party funding in collective actions, this case examined the feasibility and benefits of different collective mechanisms, reinforcing the idea that the CAT possesses significant discretion in choosing between opt-in and opt-out proceedings based on the unique circumstances of each case.

These precedents provided a foundational understanding of the CAT's discretionary powers and the legislative intent behind the collective action provisions, guiding the Court of Appeal in affirming the CAT's approach in the BT Group case.

Legal Reasoning

The Court of Appeal meticulously dissected the legal framework governing collective proceedings. Central to this was the discretionary power vested in the CAT under section 47C of the CA 1998 and further elaborated in the Competition Appeal Tribunal Rules 2015. The primary consideration was whether the claim was suitable for collective action and, crucially, whether an opt-out mechanism was more appropriate than opting in.

The CAT evaluated multiple factors, including:

• Identifiability and contactability of class members.
• The practicality and cost-effectiveness of administering opt-in versus opt-out mechanisms.
• The preference and feasibility of securing third-party funding.
• The likelihood of substantial class participation in an opt-in scenario.

The Tribunal concluded that given the substantial number of potential claimants and the relatively modest individual claims, an opt-out mechanism was indispensable to ensure that justice was accessible without the prohibitive costs and logistical challenges of requiring individual opt-in.

Impact

This judgment reinforces the CAT's broad discretion in structuring collective proceedings, particularly emphasizing the opt-out mechanism's role in enhancing access to justice for large-scale consumer claims. By upholding the CAT's decision, the Court of Appeal sets a precedent that in cases involving a vast number of affected individuals with relatively small individual claims, opt-out proceedings may be favored to ensure effective and efficient redress.

Future cases will likely reference this judgment to justify the use of opt-out mechanisms, especially in scenarios where aggregating claims would otherwise be impractical or unjustly burdensome for claimants. Additionally, the affirmation of the CAT's discretion may encourage more regulated use of collective actions as a tool against anti-competitive practices.

Complex Concepts Simplified

Opt-In vs. Opt-Out Collective Proceedings

- Opt-In: Requires individuals to actively join the lawsuit to be part of the class action. Without explicit consent, they are not included.

- Opt-Out: Automatically includes all eligible individuals in the class action unless they choose to exclude themselves.

Aggregate Damages

Unlike traditional lawsuits where each claimant's damages are individually assessed and awarded, aggregate damages involve the total compensation being calculated for the entire class and then distributed among the members. This method simplifies the process, especially when individual assessments are impractical.

Discretion of the Competition Appeal Tribunal (CAT)

The CAT possesses significant discretionary powers to determine the suitability of collective proceedings, including deciding between opt-in and opt-out mechanisms. This discretion is guided by legislative intent and judicial precedents, ensuring that proceedings are just, fair, and proportionate.

Conclusion

The Court of Appeal's dismissal of BT Group Plc's appeal in the BT Group Plc v Patourel case underscores the judiciary's commitment to upholding mechanisms that enhance access to justice for consumers. By affirming the CAT's discretion to choose an opt-out basis for large-scale collective actions, the judgment reinforces the legislative purpose of facilitating effective redress for widespread consumer harm. This decision not only solidifies the operational parameters of the CAT but also paves the way for more streamlined and accessible class actions in the future, ensuring that consumers are adequately protected against anti-competitive practices without being encumbered by cumbersome legal processes.
