Judicial decisions are influenced by myriad political factors, from lawyers and interest groups, to the shifting sentiments of public opinion, to the ideological and behavioral inclinations of the justices. Authors Lee Epstein and Thomas G. Walker show how these dynamics shape the development of constitutional doctrine. Known for fastidious revising and streamlining, the authors incorporate the latest scholarship in the fields of both political science and legal studies and offer rock-solid analysis of both classic and contemporary landmark cases, including key opinions handed down through the 2015 session. Filled with supporting material—photographs of the litigants, sidebars comparing the U.S. with other nations, and "Aftermath" boxes that tell the stories of the parties' lives after the Supreme Court has acted—the text encourages greater student engagement with the material and a more complete understanding of the American constitution.
