European Class Actions


CMS' leading class action team and unparalleled European structure develops and implements cohesive defence strategies for cross border cases.

Class actions are on the rise in Europe, and corporates are increasingly facing class actions filed in multiple European jurisdictions simultaneously. With the largest European coverage of any major law firm, CMS is uniquely placed to defend these matters robustly, whilst handling reputational and any regulatory issues. 

Class action risk is driven by local procedural law, and the diversity of rules within Europe means that corporates can face a patchwork of opt-in and opt-out claims. This requires a holistic defence strategy to address their specific threats. We identify fault lines and dispositive strategies. Opt-in claims bring particular logistical and practical challenges and our technology-driven practices deliver results whilst maximising efficiences. Opt-out claims are a new phenomenon in Europe, and require different strategies.

Most of all, we recognise that class actions can be board-level events. We support clients throughout the process and pride ourselves on the results we achieve.
