The concept of convention has been used in different fields and from different perspectives to account for important social phenomena, and the legal sphere is no exception. Rather, reflection on whether the legal phenomenon is based on a convention and, if so, what kind of convention is involved, has become a recurring issue in contemporary legal theory. In this book, some of the foremost specialists in the field make significant contributions to this debate. In the first part, the concept of convention is analysed. The second part reflects on whether the rule of recognition postulated by Hart can be understood as a convention and discusses its potential and limitations in order to explain the institutional and normative character of law. Lastly, the third part critically examines the relations between conventionalism and legal interpretation. Given the content and quality of the contributions, the book is of interest to those wanting to understand the current state of the art in legalconventionalism as well as those wanting to deepen their knowledge about these questions.
