According to Article 45 of the protocol to the Accession Treaty of Bulgaria and Romania, the new members of the Commission representing the acceding member states were appointed by the Council of the European Union in common accord with the President of the commission and after consultation with the European Parliament. Compared to former enlargements of the European Union, the Accession Treaty for Bulgaria and Romania, for the first time, contains an explicit acknowledgement of the Parliament's role and constitutes the formal legal basis for the new Commissioners' appointment procedure.
