Abstract
This chapter begins with an empirical analysis of attitudes towards the law, which inspires a philosophical re-examination of the moral status of the rule of law. The chapter analyses survey data from the US about law-related attitudes and legal compliance. Consistently with prior studies, it finds that people’s ascriptions of legitimacy to the legal system are predicted strongly by their perceptions of the procedural justice and lawfulness of police and court officials’ action. Two factors emerge as significant predictors of people’s compliance with the law: (i) their belief that they have a (content-independent, moral) duty to obey the law (which is one element of legitimacy, as defined in the chapter); and (ii) their moral assessment of the content of specific legal requirements (referred to in the chapter as ‘perceived moral content of laws’). The chapter also observes an interactive relationship between these two factors. The authors then identify a parallel (similarly interactive) modality in the way that form and content mutually affect the value of the rule of law. They argue that Lon Fuller’s precepts of legality possess an expressive moral quality, but that the extent to which their expressive effect materialises is sensitive to the moral quality of the law’s content.
