The Constitutional Principles of European Society

Abstract
Over the past decade, the European Union has witnessed the rise of a new, principled constitutionalism. At the heart of this development stands Article 2 TEU, which enshrines the constitutional principles of the EU legal order. This contribution develops the theoretical and doctrinal architecture of Article 2 TEU and explores its potential for the future trajectories of European law and society. Theoretically, it examines the provision’s legal normativity, its transformative function, its constitutional impact as well as its promises for the emergence of a European society. Doctrinally, it addresses the justiciability and interpretation of Article 2 TEU, arguing that the provision features a dual nature: it forms the thick constitutional core of the EU legal order while serving as a thinner constitutional frame for the Member States. The implications of such an understanding can be illustrated with the value of democracy at the EU level and the rule of law at the national one. Against this backdrop, this contribution explores how Article 2 TEU can become a guiding star of the future development of both the European Union and its Member States.

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.
