"Therefore, Mr President, I believe that we must be consistent, maintain our previous attitude in this respect, maintain the legal basis proposed by the Commission and endorsed by the Legal Services of the three institutions and refuse to accept this abuse of the subsidiarity theory which would truly put an end to the existence of the European Union and the competences of this Parliament."
Il convient donc, Monsieur le Président, de rester conséquents, de conserver notre position initiale à ce sujet, de maintenir la base juridique proposée par la Commission et approuvée par les services juridiques des trois institutions et de refuser cet abus du principe de subsidiarité qui sonnerait le glas de l' Union européenne et des compétences de ce Parlement.
