The fashion in which the European Union pursues its objectives has varied enormously over time. In all fronts but, in particular, as a public administration that implements the policies of the Union. Currently, the European Union’s executive action is not as it was originally designed to be. The model of executive federalism, where the Union takes decisions in the fields where it is competent and Member States implement them, was valid for the old Communities and still perceivable in the Treaties and in the rulings of the Court of Justice. Today it is often more of a legal fiction than a reality.
