This collection engages with current issues on equal protection in the USA, as seen from the perspectives of leading academics in this area. Contributors with a range of perspectives interrogate the legal, theoretical and factual assumptions which shape case law and consider the extent to which they satisfactorily address contemporary concerns with social hierarchies and norms. Divided into five parts, the study focusses on the connections between equal protection jurisprudence, discrimination in its contemporary manifestations, the implications of identity politics and the moral and political conceptualizations of equality that represent the parameters of debate. Drawing on historical analysis and disciplinary insights of the social sciences, the book bridges the gap between theory and practice. The themes presented and analyses developed are among some of the most contentious currently in America, and will be of interest not just to lawyers and legal academics, but also to inter-disciplinary social science researchers, including sociologists, economists and political scientists.
