The relationship between social, economic and other norms and legal norms is an unexplored area. There is a great deal of knowledge about social norms and legal rules separately, but not how they relate to each other. The present research project aims to remedy this by examining strategic relations in the relationship between law and society in four sub-projects: - Which norms become legal rules and why? The starting point is that law draws the boundaries of social and economic systems while at the same time providing instruments for interaction that coordinate behavior; - law upholds social and economic norms; law protects the social and economic norms that primarily govern people's actions; - law depends on professional norms from other disciplines. Legislation governing the public sector is largely based on the norms of the professions concerned, educators in schools, doctors in health care, etc. - The law as society's immune system. The law has the specific task of alleviating the conflicts of norms that give rise to symptoms of illness in society through the collision of different systems, such as in the environmental and consumer fields, in working life, etc. The sub-projects are reported on an ongoing basis and the research project ends with a concluding summary in the form of a monograph, in which the most important research results will be presented to an international audience.
