According to Article 289 of the Treaty on the Functioning of the European Union (TFEU),
Thus, for a non-legislative act to be adopted, a legislative act must first delegate to the Commission the power to adopt it. The legislative act must also explicitly define the objectives, content, scope and duration of the delegation of power to the Commission.
The delegation of power is subject to the following conditions:
Some non-legislative acts adopted in the form of regulations, directives or decisions which do not specify to whom they are addressed. In this case, they are signed by the President of the institution which adopted them.
Regulations and directives which are addressed to all EU countries, and decisions which do not specify to whom they are addressed, are published in the Official Journal of the European Union. They enter into force on the date specified in them or, if no date is specified, on the 20th day following that of their publication.
Other directives, and decisions which specify to whom they are addressed, are notified to those to whom they are addressed and take effect on notification.
