Class Actions

Class actions in Europe are on the rise, with a number of countries already adopting a US-style ‘opt-out’ model. 

CMS’ leading dispute resolution team helps clients to develop class action defence strategies aligned with their business priorities. We understand that class actions can have very significant financial and reputational impact, as well as absorbing considerable management time.

With one of the strongest European footprints of any major law firm, we can provide a cohesive defence of the largest matters, seamlessly handling multiple overlapping claims across a range of jurisdictions.
