Subsidiarity Monitoring Network 

​​The Subsidiarity Monitoring Network (SMN) was set up to facilitate the exchange of information between local and regional authorities and the Union level through the whole policy cycle regarding various documents and legislative proposals which, once adopted, will have a direct impact on these authorities and the policies for which they are responsible.

Its members include Parliaments and Governments of regions with legislative powers, local and regional authorities without legislative powers and local government associations in the European Union. It is also open to CoR national delegations and chambers of national parliaments.
