This volume contains contributions to a symposium of scholars from the Nagoya Law School and
the Faculty of Law of the Albert-Ludwigs-Universität Freiburg on the topic Reactive Instruments
of Social Governance. Together with volume 20 of the Freiburger Rechtswissenschaftliche
Abhandlungen it completes the documentation of the results of a joint research project funded
by the Nagoya Institute of Advanced Research (IAR) and the Freiburg Institute for Advanced
Studies (FRIAS). With the social governance by law and the interplay between substantive legal
standards and procedural enforcement the symposium addressed a topic of both outstanding
academic and practical importance. In the pursuit of certain political or social goals a legal
system is basically faced with two options: the exertion of influence on the behaviour of its
citizens by means of preventive or reactive instruments. The relationship of preventive and
reactive regulatory instruments is a key element for the analysisand understanding of a legal
system.
