My own hunch is that they will try to find a way to enforce the Lisbon treaty without the non-ratifiers. As a first step, they will try to offer the No-sayers a quit-and-rejoin deal. It would be the least divisive option of all, but unfortunately, it may also be one of the least realistic. It would obviously require their consent, which is far from assured. In Ireland’s case it may require a referendum to get out and another one to get back in.If this is not possible, there are several other options involving varying degrees of involuntary separation. For example, everybody would formally remain inside the EU on the basis of the Nice treaty, but the ratifiers would organise their areas of co-operation outside the EU and its institutions – on foreign policy, immigration, economic governance, maybe even on energy and the environment. They could do so using the provisions of Lisbon treaty or any other rules they choose among themselves.
