Concejo abierto
The concejo abierto is a system of government and administration of some very small Spanish municipalities and Minor [local entity|sub-municipal territorial units]. An example of direct democracy, the system allows for the existence of a mayor and a consejo or asamblea vecinal formed by all the electors of the municipality. In contrast, the conventional system used by most municipalities is the ayuntamiento, often translated as city, town or municipal council in English, comprised of the local councillors who form the plenary, and the Mayor, elected in turn by the councillors among themselves.
History
The origins of the system trace back to the Middle Ages, as a custom primarily originated in the Kingdoms of León and Castile, although it also extended to other territories as well, chiefly in the north of the Iberian Peninsula. In many settlements, the concejo abierto was replaced by the "regimiento" system, in which a decision-making body of limited size formed by judges or alcaldes as well as a number of regidores appointed by the King was contemplated; in the case of Castile, this process chiefly took place between 1345 and the later years of the rule of Alfonso XI.The contemporary form of the concejo abierto is recognised in the 1978 Spanish Constitution.
