IEA Calls for Reform of UK Class Action System, Citing £134 Billion in Claims
The Institute of Economic Affairs (IEA) has issued a call for major reform of the UK’s collective proceedings regime, warning that the current system invites economically inefficient claims and undermines justice for consumers.
An article in ICLG reports that the IEA estimates over £134 billion in pending class action claims are currently before the Competition Appeal Tribunal, involving approximately 655 million potential claimants—more than ten opt-out claims for every person in the UK. While the regime was initially designed to allow consumers to pursue redress in competition cases, the IEA argues it has increasingly been used for speculative litigation, often delivering poor outcomes. The report cites the Merricks v Mastercard case, which originally sought £14–17 billion but ultimately settled for just £200 million, or less than two percent of the original amount.
The IEA’s critique also extends to the litigation funding models supporting these cases. Following the UK Supreme Court’s 2023 decision in PACCAR, which restricted certain types of litigation funding agreements, the IEA contends that funding arrangements still misalign incentives and may delay compensation to claimants. Among the reforms it proposes are: requiring early payments to a portion of class members before a case is certified; establishing a public valuation mechanism to promote competition among funders; enhancing the economic analysis applied at the certification stage; and simplifying damages assessments by focusing on first purchasers rather than tracing harm down complex supply chains.
While the IEA acknowledges that the opt-out class action system has value, it argues that without reform, it risks damaging business confidence, overburdening the courts, and eroding trust in the legal system. Critics of the report, including funder Winward Litigation Finance, suggest some of the recommendations are impractical and fail to grasp the realities of litigation finance.
