Karlsruhe über alles? The reasoning on the principle of proportionality in the judgment of 5 May 2020 of the German BVerfG and its consequences

The judgment of 5 May 2020 of the zweiter Senat of the Bundesverfassungsgericht, to the extent that it expresses the German constitutional judge's claim to assess the legality of the ECB's decisions on the basis of the principles of attribution and proportionality, is more than questionable in point of law. Furthermore, it is extremely dangerous: and not only because it implies that the zweiter Senat ultimately refuses, on the basis of the democratic principle and the control of the Union's competences, the uniformity of application of EU law. But also because it appears as the glaring demonstration of a form of "cultural bullying" many complain about, and which emerges in a crystal clear way in the reasoning carried out on proportionality. This is an attitude which, in the contingency caused by the COVID-19 emergency, could have truly tragic consequences for the future of the European Union.
