It could mean a great deal. There are two main concepts; there are a number of subsidiary concepts. One approach is to list all the things that will remain at national level and those that will stay at Community level. Another approach is to list all the things that will never be ceded to the Community. We are very far from agreement on the principle of subsidiarity.
We would favour a system of subsidiarity, in other words, that those things which are best done at member state level be left to the member states to do, subject to the very important qualification that the legal limits must be fairly clearly defined and, secondly, that it would not mean a reversal of important common Community policies to national level — policies such as the Common Agricultural Policy. We would be very anxious that the main Community policies would not be interfered with by any application of the principle of subsidiarity. We would also wish to see the new principle we are advocating in regard to economic and social cohesion would be very definitely a Community policy.
