Senator McDowell made the point that we must learn from the last referendum. We need to look at the reports. He mentioned the Committee of the Regions. An interesting report has been produced by one of the working groups which deals with subsidiarity within the convention. There is a related report by one of the working groups that deals with the role of national parliaments. If the Seanad decided to debate this area, it would be interesting to discuss those issues. Subsidiarity and its meaning are being dealt with. It is interesting how they are being dealt with by the convention. It has recognised that, although the term "subsidiarity" has been broadly used before, it has not been tightly tied down.
