The convention has also taken a significant step forward in enhancing the role of national parliaments and in monitoring the application of the principle of subsidiarity. Commission proposals will be sent to national parliaments at the same time as they are sent to governments and the European Parliament, and national parliaments will be empowered to object to the proposals if they feel that subsidiarity has not been respected. This innovation will be very welcome to Members of this House. Where one third of parliaments, or more, objects, the Commission will be obliged to reconsider its proposal. At the end of the legislative process, if parliaments feel their concerns still have not been addressed, they can have recourse to the European Court of Justice.
