The relationship of the EuGH and the EuG to the national courts is a practically inexhaustible subject. It provides an opportunity to make certain about the arrangement of the European constitutional confederation in view of increasingly newer developments. The way in which European and national jurisdictions relate to one another permits conclusion to be drawn on the level of integration that has been achieved, the relationship of national to European (constitutional) law and on the nature of the European Union itself.
