We are grateful to all contributors or their work, commitment, and passion for this project. We studied how exclusionary rules are established in the respective procedural codes and how they are applied in practice, with a focus on case law, and conducted interviews in almost all relevant jurisdictions. We explored the potential of alternative and supplementary means of compelling law enforcement to respect human rights, including criminal sanctions, disciplinary action, and civil liability. Throughout the project, we learned a great deal from each other. National issues and legal solutions, as well as comparative issues and basic principles, were discussed at two workshops and conferences. The first meeting took place in March 2016 in Taipei, Taiwan, and was co-organized by the Taiwan Ministry of Justice. We are especially grateful to Pauline Tsai for her exceptional support. The second meeting occurred in May 2017 in Basel, Switzerland, and received remarkable financial support from the Sino-Swiss Science and Technology Cooperation Program of the Swiss National Research Foundation. Major financial funds for this project, including the publication of its results, have been provided by the Swiss National Research Foundation and without it, the project could never have been realized. We are very grateful for the Foundation’s generous assistance and enduring support.
