The End of Satellite Treaty Law as We Know It? The German Federal Constitutional Court, European Integration by International Law and Treaties “Supplementing or Being Otherwise Closely Tied to the EU”

Abstract

AbstractAmidst the first wave of the coronavirus pandemic, the German Federal Constitutional Court rendered a little-noticed, but potentially far-reaching decision regarding European integration. When it declared the law ratifying the Unitary Patent Court Agreement unconstitutional, it did so because it is a treaty “supplementing or being otherwise closely tied to the EU”, in other words, a satellite treaty, inter-se agreement, or more generally: an international law agreement furthering European integration outside the EU law framework. This commonly used integration technique is therefore going to be a lot more difficult in future whenever Germany is involved. At the same time, the court order gives all German citizens a far-reaching right to have laws ratifying such treaties checked before the Constitutional Court, which is a significant extension compared to its earlier case-law. In future cases of disagreement, EU Member States may have to find different ways to proceed than resorting to international law, such as using the enhanced cooperation mechanism.
