So far, the German Constitutional Court (Bundesverfassungsgericht, henceforth:BVerfG) has only made a single preliminary reference to the (now) Court of Justice of the European Union (CJEU), despite frequent rulings on matters connected with European Union (EU) Law. Its apparent reluctance seemed odd considering the atmosphere of dialogue and cooperation which prevails between the non-constitutional courts and the EU courts. This situation might, however, have changed with the preliminary reference from January 2014, proving predictions on the perceived “most powerful constitutional court” and its relationship to the EU partly wrong. The legal effects of its preliminary reference on the interpretation of Articles 119, 123, 127 ff. of the Treaty on the Functioning of the European Union (TFEU) and the validity of Outright Monetary Transactions (OMT) by the European Central Bank (ECB) under EU Law are as yet unclear; although the Opinion of the Advocate General Cruz Villalón was delivered in the beginning of 2015, which did not confirm the doubts expressed by theBVerfGabout the conformity of the OMT programme with EU law. Nonetheless, the interpretative scheme and the normative questions as to the reluctance of theBVerfGremain the same after this single referral and offer explanations as to why theBVerfGhad for nearly sixty years not referred a question to the former European Court of Justice (ECJ).
