This Report examines the extent to which the specialised units within the EU that investigate and prosecute serious international crimes uphold EU standards on victims’ rights. It is based on research conducted between 2019 and 2020, including approximately 140 interviews with practitioners and policy makers in five Member States—Belgium, France, Germany, the Netherlands and Sweden. The Report includes five country chapters that examine the law and practice in these countries as well as an analysis of common challenges and emerging best practices. It provides a roadmap for improving victims’ access to information, protection and support.
