This book deals with the subject of class arbitration in the European Union. It investigates to what extent class arbitration (either US style or a European variant) may take place in Europe and to what extent class arbitral awards are enforceable in European jurisdictions, such as France, the Czech Republic, Denmark, Hungary, Italy, Portugal, Spain, Sweden, the United Kingdom, Belgium, and the Netherlands. The authors are among the world's leading arbitrators and academics in the field of arbitration. This volume serves as a critical study for shaping future practice and setting out future rules, policies, and guidance in relation to class arbitration and collective remedies. It will be an indispensable addition to every ADR practitioner's library.
