This article presents an analysis of recent evidence emerging from the building industry about British state tolerance, and encouragement, of an illegal ‘blacklist’ of workers in the industry. As part of this process, the article argues that the form of policing/regulation that is observable in the case of the blacklisted workers is one that ultimately seeks to guarantee as its primary concern, not the rule of law, but the orderly reproduction of surplus value in the building industry. The article does not suggest that the latter purpose is all that concerns policing/regulation, but it does suggest that it is the principal effect of a combination of various policing and regulatory techniques. In order to achieve orderly reproduction of surplus value, it is argued that building workers are confronted by a form of economic force which is given shape by, and ultimately underpinned by, the system of policing/regulation that at the same time, claims to protect them.
