Not European politicians.

You see, in the EU international treaties supersede individual countries' constitutions in theory. This is the other way the EU is moving power to executive governments away from parliament and judicial branches.

Of course, in practice, you have at least a good chance that courts just ignore it (of course the laws of many European countries are a good match, the big thing you get many conflicts about is if 2 governments act on the same company/crime/...). Then the EU court makes a counter judgement ... and is ignored, despite the law. Which is one of the reasons you keep reading the EU is about to fall apart.
