The legislative process has not traditionally been a central concern of sociolegal scholars, but has remained within the territory of political science. This paper argues that sociologists of law have an important contribution to make to developing the sociology of the legislative process, and that an understanding of legal processes and ways of thinking could enrich the study of public policy from the development of a new policy idea, through the strategy for preparation and, finally, the parliamentary management of a new statute.
