WAMCA Procedure Explained for Amsterdam Residents
The WAMCA procedure (Act on the Settlement of Mass Damage Claims in Collective Actions) offers residents of Amsterdam and surrounding areas a powerful mechanism to collectively pursue damages against companies or governments responsible for large-scale harm. Since January 1, 2020, this legislation provides a clear pathway for collective claims, imposing strict requirements on initiators and offering robust protections for affected individuals in the region.
What is the WAMCA procedure?
Under the WAMCA procedure, groups of Amsterdam residents can collectively claim damages for incidents such as defective products, misleading advertising, or major data breaches. This approach consolidates individual claims to reduce litigation and attorney costs while strengthening negotiating power. It builds on collective actions and mass claims. All cases are handled exclusively by the Amsterdam District Court, the specialized forum for such matters.
Legal basis
The WAMCA is codified in Title 3A of Book 3 of the Dutch Civil Code (DCC), articles 7:178 to 7:191 DCC. Compared to the former WCAM (2005), it introduces an opt-in system for consumers and higher standards for representative organizations. This bolsters consumer rights in the Netherlands, aligning with EU rules such as the Representative Actions Directive.
The WAMCA procedure step by step
The procedure follows a structured process at the Amsterdam District Court. Here are the phases:
- Issuing the summons: A certified representative organization (with ANBI status and representative rights) initiates proceedings with a summons at the Amsterdam District Court, detailing the cause of damage, affected parties, and requested compensation.
- Hearing: Within 13 weeks, the court assesses admissibility; parties are heard.
- Ruling on admissibility: If approved, notice is published in national media and on a website. Amsterdam consumers have 3 months to opt in.
- Damage assessment: An agreement binds opt-in parties immediately. No agreement? A phase follows for collective or individual calculation.
- Enforcement and appeal: The settlement or judgment is executed; appeal is possible to the Amsterdam Court of Appeal.
On average, cases take 1-3 years, depending on complexity.
Admissibility requirements
The Amsterdam District Court verifies five criteria (art. 7:181 DCC):
- Adequate representative organization.
- Sufficiently representative interest warranting review.
- Claims for mass damage arising from liability law violations.
- No statute of limitations or laches.
- Suitable for collective resolution.
Not admissible? Dismissal follows, but individual claims remain available for Amsterdam residents.
