In the past decades, the European Union has made little progress with respect to disqualifications as a sanction mechanism for the violation of laws. The creation of some form of harmonization is necessary, but the complex nature of this specific sanction mechanism has caused policy initiatives to be postponed, time after time. In answer to a call from the European Commission, the contributors in this book have conducted a comparative legal analysis in the EU 27 and looked into the practical experiences with disqualifications from a domestic and a cross border perspective. To that end, academics, policy makers, and practitioners in the Member States have been consulted. Analysis reveals a wide variety in the typology of the disqualifications as a sanction measure, the typology of the persons to whom the disqualifications can be imposed, and the typology of the authorities involved. Furthermore, there are considerable differences with respect to the inclusion of disqualifications in the national criminal records databases. Linked thereto information on foreign disqualifications is scarce and rarely used in practice. To ensure a comprehensive and consistent policy approach, this book has come up with a so called disqualification triad, comprising: (1) unified EU-wide disqualifications, (2) mutual recognition of disqualifications, and (3) EU-wide equivalent effect of disqualifications. The functioning of the disqualification triad has been further elaborated on in three case studies, which are public procurement disqualifications, disqualifications from working with children, and driving disqualifications. In doing so, this book is essential reading for both EU and national policy makers, as well as for researchers and practitioners involved.
