That's not it though.

ECJ rulings are the law of the land as far as they see it, not a 'recommendation'.

There are no rules around sanctions etc. for countries that don't 'comply'.

It's just 'make it up as they go along'.

The problem is: there is no treaty basis for ECJ Supremacy. By opening that can of worms, the EU may find themselves with a 'big losing hand' and more affirmatively lose their power.

As I pointed out in the previous comments, the issue is unsettled even in Germany.
