Whether nonsense or not, nanne is correct. The Constitutional Court has consistently asserted its right to review EU initiatives for conformity with the Basic Law. Some articles elsewhere have touched on the potential for conflicting jurisdiction.

But when viewed in context, I don't think it's nonsense at all: the job of a constitutional court is to uphold the constitution, no? If the issue is important enough, the constitution can be amended. But it is the court's job to see that everything is done in plain sight, and not through the back door.

Just as an aside, it is interesting to note that it is the written constitutions which are amenable to amendment, and the unwritten ones - like England's - that are written in stone.

The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
