In addition, six national Parliaments (the Spanish Cortes Generales, the Italian Camera dei Deputati, the Portuguese Assembleia da República, the House of Commons of the United Kingdom, the French Sénat and the Italian Senato della Repubblica) sent opinions in the framework of the political dialogue mainly considering the proposal as compatible with the principle of subsidiarity.
Peale selle esitasid kuus liikmesriikide parlamendikoda (Hispaania Cortes Generales, Itaalia Camera dei Deputati, Portugali Assembleia da República, Ühendkuningriigi House of Commons, Prantsusmaa Sénat ja Itaalia Senato della Repubblica) poliitilise dialoogi raames oma arvamuse, mille kohaselt kõnealust ettepanekut peeti enamjaolt subsidiaarsuse põhimõttega kooskõlas olevaks.
