Until the 1990s, constitutionalism in Eastern Europe was considered to be an outmoded concept of the nineteenth century. Changes in the region, however, have brought back the fundamental question of the need to restrict government power through social self-binding.;This text discusses the mechanisms of such restriction, including different forms of the separation of powers and constitutional review. It relates the theoretical and practical importance of the issue to the present worldwide discontent with majoritarian democracy and the growing disrepute of parliaments.;Increasing executive efficiency is, however, a threat to fundamental rights, and the battlecry of efficiency is often only a means to new despotism and inefficiency. A careful re-evalution of the concept of constitutionalism assists in the search for a useful balance between majoritarianism and rights, and in the avoidance of all forms of public tyranny.;Written in non-technical language and using the most important English, American, French, and German examples of constitutional history, the book also examines East European (in particular, Russian) and Latin American examples, in part to illustrate certain dead-ends in constitutional development.
