Ernst-Wolfgang Bockenforde (b. 1930) is one of Europe's foremost legal scholars and political thinkers. As a scholar of constitutional law and a judge on Germany's Federal Constitutional Court (December 1983 - May 1996), Bockenforde has been a major contributor to contemporary debates in legal and political theory, to the conceptual framework of the modern state and its presuppositions, and to contested political issues such as the rights of theenemies of the state, the constitutional status of the state of emergency, citizenship rights, and challenges of European integration. His writings have shaped not only academic but also wider public debates from the 1950s to the present, to an extent that few European scholars can match. As a federal constitutionaljudge and thus holder of one the most important and most trusted public offices, Bckenfrde has influenced the way in which academics and citizens think about law and politics. During his tenure as a member of the Second Senate of the Federal Constitutional Court, several path-breaking decisions for the Federal Republic of Germany were handed down, including decisions pertaining to the deployment of missiles, the law on political parties, the regulation of abortion, and the processof European integration. In the first representative edition in English of Bckenfrde's writings, this volume brings together his essays on constitutional and political theory. The volume is organized in four sections, focusing respectively on (I) the political theory of the state; (II) constitutional theory; (III) constitutional norms and fundamental rights; and (IV) the relation between state, citizenship, and political autonomy. Each of these feature introductions to the articles as well as a runningeditorial commentary to the work. A second volume will follow this collection, focusing on the relation between religion, law, and democracy.
