Collective proceedings in the Competition Appeal Tribunal: taking stock and looking ahead

A new collective actions regime for competition damages claims was introduced in the UK in 2015. Although seven proposed collective proceedings have been brought since that time, none have, as yet, continued beyond the certification stage, and no further cases are likely to proceed to a full certification hearing pending an appeal to the Supreme Court in the Merricks v Mastercard proceedings in 2020. It is, therefore, an opportune time to take stock of the new regime. This article explores the development of the regime to date, considers what lies ahead, and assesses the overall status and progress of the regime. It is suggested that the forthcoming Supreme Court appeal in Merricks provides a welcome opportunity both to build on the significant progress that has already been made on a number of key aspects of the new regimen over the past four years, and to redress some of the legal and policy implications of the recent Court of Appeal judgment in the Merricks proceedings, which risk undermining the important ‘gatekeeping’ function afforded to the Competition Appeal Tribunal under the legislation. The UK collective proceedings regime ought to then be on a strong footing to resume, albeit its development will remain necessarily iterative and cumulative as further important aspects of the new regime are considered by the CAT and appellate courts over the coming years.
