  There is yet another argument for including a right to secede in a constitution. In some cases, when a new political entity is being created out of two or more independent or semi-autonomous entities, including a right to exit in the constitution of the new entity may be necessary as an inducement to join the new union. Under conditions of uncertainty as to how the new union will work, constitutional recognition of a “bail out” option may be necessary to get the new union going   (Buchanan 1991: ch. 4).[4]
