Collective actions and the financing of complex mass damage cases have been among the most debated and controversial topics in civil justice in Europe over the past decade. With the entry into force of the Dutch collective damages procedure (WAMCA) in 2020, the Netherlands has re- confirmed its reputation as one of the frontrunners in having a welldeveloped framework for collective actions and settlements. Third party litigation funding has become an important source of funding, and its increase has also fuelled discussion on alternative pathways for funding to secure access to justice. This book discusses developments in Dutch collective actions and in particular the financing of collective actions from a regulatory, empirical and comparative perspective. It delves into different funding modes, including market developments in third party litigation funding, and extensively addresses the question of the necessity, feasibility and possible design of a (revolving) litigation fund for collective actions. It is of interest to academics, legal practitioners, national and European policy makers and legislators in the area of civil justice. 1 Introduction: Collective Actions and Funding Needs under the WAMCA; 2 The Dutch Collective Action Regime, Financing Options and Regulation of Third-Party Litigation Funding; 3 Analysis of the WAMCA Register; 4 Qualitative Analysis of Financing Collective Actions: Interviews; 5 Findings from the Focus Group and Expert Meeting; 6 Financing and Litigation Funds for Collective Actions in Canada, Australia and Israel; 7 Analysis, Conclusions and Recommendations
