Constitutional Law Court’s ultra vires review of EU law, but similar actions by other European institutions have mostly stayed under the radar.
Both the European Court of Justice and the Bundesverfassungsgericht have given their blessing to the ESM. Yet it appears that they think very differently about the central prohibition on bailout.
Eurozone leaders recently decided that the ESM should expand its powers and provide direct aid to banks. Is this allowed under the current ESM treaty or is a treaty change (and thus a new round of ratification of national parliaments) necessary?
