In March, the third volume of the "Max Planck Handbooks in European Public Law"[1] edited by Armin von Bogdandy, Peter M. Huber und Christoph Grabenwarter was published. The volume entails a contribution by Anuscheh Farahat adressing the adjudication of the German Federal Constitutional Court. She describes how the court deals with the challenge of European Integration and discusses how its reasoning and decisions relate to the development of a European legal sphere.
