This Research Handbook is a multi-faceted, comparative analysis of how law and political systems interact around the world. Chapters include analyses of judicial deference, congressional support, democratic representation, politicization of courts, public support, and judicialization across multiple jurisdictions in the United States and abroad. Chapters also investigate transnational courts and the linkages between international and domestic law and politics. Addressing these relationships from a comparative perspective, the Handbook illustrates how different political contexts lead to different uses of law and how courts respond to divergent political environments. An impressive array of contributors, and the editors, examine law and political systems on a global scale through either country-specific analyses, comparative analyses, or the examination of transnational institutions. Scholars interested in law and courts, judicial politics, the rule of law, and governance will find this Research Handbook to be a valuable resource. It will provide a helpful foundation for advanced students of both political science and law and will be a useful reference tool for judges and those operating in a judicial or political sphere.
