Collective Proceedings for Damages in UK Competition LawCase Comment to the Judgment Merricks v Mastercard [2019] EWCA Civ 674

Abstract

Merricks v Mastercard [2019] is the first action under the newly developed ‘opt-out’ collective proceedings regime for aggregate damages under UK competition law to be considered by the UK Court of Appeal. It is significant for both the level of damages (£14 billion (€16 billion)) and the clarification of the legal test at the certification stage for the suitability for an aggregate award: the method for calculation of the aggregate damages and the sufficiency of evidence. The Court’s lowering of these thresholds importantly opens the door to future class actions and reasserts the importance of collective proceedings as a valuable means of redress for competition law infringements. The decision has now been appealed to the UK Supreme Court where these issues may be further clarified and resolved.
