The European Union, as a union of states of very different political configuration, integrates different levels of government within it. These levels of government are recipients of European norms and policies, but in many cases they are also the entities in charge of their application, development and execution. The community principles of normative production favor the intervention of European regions, since they enhance the intervention and participation of all actors, understanding that the norms are of better quality when all possible subjects, interested or not, have intervened in their creation. that may have an implication with them.
