Since 2010 the EU has been in an ‘emergency’ situation due to the eurocrisis, where the crisis management by the EU institutions, notably the European Central Bank (ECB), and national governments has been increasingly out of step with the EU Treaties which define the scope of the mandate of the ECB and the EU’s economic policy powers as well as the conditions and limits subject to which Member States have transferred policy and lawmaking powers to the EU in accordance with their national constitutions. The ECB is independent of parliamentary control, which means that it is not accountable to national parliaments and merely has a reporting duty to the European Parliament. Exempt from democratic control the ECB is subject only to judicial review at both EU and national level. At EU level, the competent court is the Court of Justice of the EU (CJEU) which claims the right to be the sole arbiter over the interpretation of EU law.
