The Significance of the 5 May 2020 Judgment of the Constitutional Court of the Federal Republic of Germany (Weiss II) for the Process of Integration of the European Union Financial Market

Since the financial crisis of 2007/2008, we have been dealing - at the level of the European Union - with a special "dialogue" between the European and German courts. The subject of this "dialogue" is the decisions of the European Central Bank on the program for the purchase of public sector assets on secondary markets. The ECB's activity, as well as the involvement of the national central banks of the Eurosystem in the implementation of these decisions, has been met with dissatisfaction by German politicians, culminating in the title judgment of the Constitutional Court of the Federal Republic of Germany. In the paper, the author analyzed the judgments, particularly from the perspective of the process of integration of the European Union financial market and the importance of the judgments for this process taking into account the key principles of EU law: proportionality and supremacy of EU law.
