This chapter compares sociopolitical perspectives of the law in the United States and France. Despite their heterogeneity, these perspectives share many practical and theoretical similarities. For this reason, the chapter proposes grouping them under the more general title of sociopolitical legal studies (SLS). This general label includes a collection of transdisciplinary research, theories, and studies that view law as a sociopolitical phenomenon central to the understanding of power and society. The concept of SLS reveals the existence of a transversal ground between three academic disciplines: sociology of law, legal theory, and socio-legal studies, which, in spite of multiple connections, rarely communicate with one another. Additionally, the term “studies” is used in a broad sense, including not just legal theories but also empirical analyses of the law.
