Subsidiarity - local authorities and town and parish councils

The recent White Paper about local government opens a useful debate about transferring powers from the big local authorities down to town and parish councils. I think there is also a principle of "subsidiarity" involved in all this - things should be done at the lowest level that it makes sense to do them at. A good example was that issue a while back over the extra taxi parking space, which suddenly appeared in Pocklington at the behest of East Riding Council and without any local consultation. Taxi spaces don't need to be decided by Brussels, or London, or East Riding Council in Beverley - surely that is a job for the local community and the elected Town or Parish council?
