1. Effective implementation of Union law by the Member States, which is essential for the proper functioning of the Union, shall be regarded as a matter of common interest.
2. The Union may support the efforts of Member States to improve their administrative capacity to implement Union law. Such action may include facilitating the exchange of information and of civil servants as well as supporting training schemes. No Member State shall be obliged to avail itself of such support. European laws shall establish the necessary measures to this end, excluding any harmonisation of the laws and regulations of the Member States.
3. This Article shall be without prejudice to the obligations of the Member States to implement Union law or to the prerogatives and duties of the Commission. It shall also be without prejudice to other provisions of the Constitution providing for administrative cooperation among the Member States and between them and the Union.
