Mass Litigation

Mass litigation is accelerating across sectors, driven by third-party funding and procedural reforms such as the Dutch WAMCA, which enables opt-out claims for damages but meanwhile imposes stricter admissibility criteria.

We have played a pivotal role in some of the largest mass claims and class actions in the Benelux, leveraging our firm’s extensive expertise to achieve optimal outcomes for our clients. We provide legal assistance in both national and international contexts, combining expertise in procedural law with areas such as antitrust and cartel damages, consumer protection, data privacy, ESG issues, and financial law.
