Following the entry into force of the Lisbon Treaty, national parliaments have a greater say in European affairs. The Treaty recognises their role as "contributing actively to the good functioning of the Union", and national parliaments are now directly consulted in the European decision-making process. In particular, they ensure the correct application of the principle of subsidiarity, which means that decisions should be taken at the most appropriate level. National parliaments have the power to intervene at a very early stage, when a European legislative act is still a Commission proposal awaiting adoption by the European Parliament/Council of Ministers.
One of my key priorities has been to ensure that the active and constructive role of National Parliaments in European policy-making is further strengthened. I am personally committed to further developing and deepening the Commission's relations with National Parliaments and to establish a true political partnership with them, in full respect of the respective prerogatives of the EU institutions.
As a concrete illustration of this partnership, listed below are all the opinions received from national parliaments, and the replies I sent them on behalf of the Commission.
