Legal Regulation and Communicative Couplings

From 1989 to 1991 we studied the relationship between legal regulation and decisions about acceptable risk at off‐shore installations in the North Sea. The study focused on the interaction between authorities and private actors, when they develop subsidiary rules, discuss projects, and execute audits. This article discusses the case of regulation within the framework of communicative systems theory; the problem is how to couple differentiated, closed functional systems (e.g., law and economy). Applying empirical data we attempt to create a more complex understanding of the communicative processes, on the basis of which we can elaborate upon the coupling between systems, and the potential effects of law. The point of the article is that the coupling itself may develop into a new independent system (the discursive system). If this is correct and fairly generalizable, legal regulation contributes to the differentiation of society into closed systems. At the practical level the differentiation will have consequences for both regulation and democracy.
