Exploring the growing significance of the administration of justice in both democratic and non-democratic countries, often labeled as 'the judicialization of politics', this timely book considers how increased levels of interest in the analysis of judicial institutions have been triggered. It examines the expansion of the role of judges and courts in the political system and the mixed reactions generated by these developments. In this comprehensive book, Carlo Guarnieri and Patrizia Pederzoli draw on a wealth of experience in teaching and research in the field, moving beyond traditional legal analysis and providing a clear, concise and all-encompassing introduction to the phenomenon of the administration of justice and all of its traits. Facilitating a deeper understanding of the concrete dynamics characterizing the judicial system and its relationships with the political environment, it also offers a balanced assessment of the process of judicialization. Students and scholars interested in comparative law and politics, and law and society, who wish to broaden their understanding of courts and the operation of the judicial system will find this to be a valuable resource. The wide coverage of cases from both common and civil law traditions will also appeal to practitioners.
