Merricks v Mastercard: the litigation risks for the financial services sector

Herbert Smith Freehills LLP have published an article in Butterworths Journal of International Banking and Financial Law on the repercussions of the recent decisions in the Merricks v Mastercard litigation for the wider litigation landscape, particularly for the financial services sector.

Historically, the most common procedural mechanism for bringing class actions in the UK has been by way of a Group Litigation Order (GLO), which provides a procedural framework for the case management of individual claims giving rise to common or related issues of fact or law. Such claims are often contractual or tortious in nature, and there are a number of examples of high-profile claims against financial services firms in recent years that have proceeded under a GLO (for example, in relation to alleged misstatements in shareholder communications and allegations of financial mis-selling).

However, in one of the most significant rulings on class action procedure to date, the Supreme Court in Merricks v Mastercard provided important clarifications on the UK competition class action regime, leading to the first application for a collective proceedings order (CPO) being approved by the Competition Appeal Tribunal in August 2021. For the reasons discussed in our article, the competition regime has features that are perceived as “claimant-friendly”, and its endorsement has triggered a series of further CPO applications. The anticipated growth of the regime following the decision in Merricks is likely to have an impact beyond the sphere of competition law, and our article explores the potential ramifications for class actions in the financial services sector.
