The question of whether EU law is superior to national law is subject to some debate. The treaties do not give a judgement on the matter but court judgements have established EU's law superiority over national law and it is affirmed in a declaration attached to the Treaty of Lisbon (the European Constitution would have fully enshrined this). Some national legal systems also explicitly accept the Court of Justice's interpretation, such as France and Italy, however in Poland it does not override the national constitution, which it does in Germany. The exact areas where the member states have given legislative competence to the EU are as follows. Every area not mentioned remains with member states.
