Contrary to the wide acclaim of the Commission for the opening of an infringement procedure against Germany over the Weiss ruling, we argue that the infringement procedure is an ill-conceived attempt to attain what in the current EU institutional framework is unattainable: the affirmation of European law as the ultimate gatekeeper of legal validity in Europe. What is more, we observe that the Commission leaves unaddressed the most pressing issue emerging from the Weiss saga: the need to secure a more robust legal basis to the unconventional monetary policy of the European Central Bank.
