Is the public-private divide still a relevant distinction in legal and in regulatory practice and does it makes sense to continue to research legal phenomena from the presumption that 'public' and 'private' represent truly distinctive normative orientations? This volume is about such questions and aims to, rather than to try and answer these questions, let alone definitively (if that were a reasonable option anyway), look at both legal practice and at legal research and try to learn from examples of problems and approaches that fit the focus of governance. This is done in this volume under the umbrella of four themes: Public & Private, Law & Regulation, Law & Technology, Governance & Legal Methodology.
