    “US Class Action and European Representative Actions”

    US Class Actions are a feature of US litigation, which is well-known and sometime misconceived far beyond the United States. The member states of the European Union will introduce representative actions for the protection of collective interests of consumers by 25 December 2022 under Directive 2020/1828.

    Join us on 9 December 2021 for a discussion on the principles of class actions and whether or not they could serve as a model for representative actions in the EU with class action focused attorney Mike Lowenberg and our Vienna partner Alfred Siwy moderated by our New York/Houston of counsel Nicholas Paine.
