There is provision for referendums at both the local and regional levels in Albania, Bulgaria, Croatia, Hungary and Sweden. In the Netherlands, referendums could be held in provinces and municipalities from 2002 to 2004; in Poland, in regions, districts and municipalities. France provides for local referendums at the regional, department and municipal levels; it also holds institutional referendums within specific territories (overseas territories, Corsica), relating to the status of the territory in question as a unit of government. The Portuguese constitution provides for regional referendums in the Azores and Madeira autonomous regions, but an “organic” law must be passed before such referendums can be held.
