The work has three main objectives: to provide deeper understanding of the problems of legal change within the diversity of Western political and legal thought; to examine the development of the processes of change in terms of their normative and prudential acceptability; to interpret actual processes of change with a view to the general theoretical and normative background. The book is divided into three parts: Part I sets the scene and is focused on the general issues important for understanding and evaluating legal change from the perspective of political philosophy; Part II focuses on the spectrum of politico-philosophical justifications present in the political culture of democratic states; Part III offers selected case studies to specify and apply the philosophical ideas in the previous parts. The book will be a valuable resource for students and scholars of law and jurisprudence, including comparative legal studies and human rights law, political theory, and philosophy.
