The UK introduced a new collective proceedings regime for competition damages claims in October 2015.[1] The early years of the new regime were characterized by cautious uncertainty as the Competition Appeal Tribunal (CAT) and the appellate courts grappled with identifying the standards for certification.[2] It took almost six years before the CAT certified the first claim in Merricks in August 2021.[3] The CAT subsequently certified 10 other claims in less than two years, which in turn, encouraged additional claims to be brought.
