Regional Boundaries

(1) By means of a constitutional law, the regional Council having been consulted, existing Regions may be merged, or new Regions created, provided the population of any new Regions is at least one million, when the request has been made by a number of Municipal Councils representing no less than one-third ofthe populations involved, and the request has been approved by referendum by a majority of said populations.

(2) The Provinces and Municipalities which request to be detached from one Region and incorporated in another may be allowed to do so, following a referendum and a law of the Republic, which obtains the majority vote of the populations of the Province or Provinces and of the Municipality or Municipalities concerned, and after the Regional Councils have been consulted.
