WAMCA is the Dutch Wet afwikkeling massaschade in collectieve actie (Act on the Resolution of Mass Damages in Collective Action), which entered into force on 1 January 2020. It allows a representative foundation to bring a single collective action on behalf of all affected parties, including non-Dutch EU residents in many cases.
Collective proceedings under WAMCA typically take several years from filing to first-instance judgment, with possible appeals adding further time. Detailed timelines for each active proceeding are published on the respective claim pages.
The foundation processes claimant personal data only as needed for the proceedings, under Dutch and EU data protection law (GDPR). Data is retained for the duration of the proceedings and a reasonable period thereafter. The full privacy policy is available on the website.
Individual claimant identities are not made public. Aggregate statistics about the size of the represented group may be published as part of court filings or transparency reporting.
Independent, transparent, and accountable. The foundation operates under Dutch law as a Stichting with public governance and audited financials.
