Within the European Union, "Regulations" are legal acts after a European Union legislative procedure. From the twentieth day following their publication in the "Official Journal of the European Union", they enter into force and they are legally "binding in [their] entirety and directly applicable in all Member States", simultaneously. Unless through due to some legal reasons reason or a derogation, a Regulation becomes enforceable as law - and mediation into national law is not required, since inconsistent national law on the same subject is overwritten. Consistency of subsequent national law with regulations of the European Union has to be respected.
