This is the appeal stated by Lüder Gerken, director of the Centre for European Policy, and Roman Herzog, former President of Germany and former judge at the German Federal Constitutional Court. They illuminate their reasons behind this rather radical-sounding position in an article published in the German newspaper Frankfurter Allgemeine Zeitung from the 8 September. An english translation of this quite interesting article can be found here. An extract:
Judicial decision-making in Europe is in deep trouble. The reason is to be found in the European Court of Justice (ECJ), whose justifications for depriving Member States of their very own fundamental competences and interfering heavily in their legal systems are becoming increasingly astonishing. In so doing,it has squandered away a large part of the trust it used to enjoy.
