The current Constitución was passed by the Cortes Generales (Plenary Meetings of the Congress of Deputies and the Senate) on 31 October 1978, then approved by national referendum on 6 December, and received royal assent on the 27 December.
Its contents are grouped into 11 Títulos (titles/parts), which are made up of Capítulos, made up of Artícolos (some of which may have numbered sections) Citation is usually direct to the article number(section number) eg. Art.16(3) (No established religion.)
The relationship between the Constitution and European Community/Union is usually a topic considered in works considering constitutional law.
Autonomous Communities are recognised in Title VIII of the Spanish Constitution, e.g. Art. 143 (2):
In the exercise of the right to self-government recognised in Article 2 of the Constitution, bordering provinces with common historic, cultural and economic characteristics, island territories and provinces with historic regional status may accede to self-government and form Autonomous Communities in accord with the provisions contained in this Title and in the respective Statutes.
Since the democratic transition in the 1970s, some powers have been devolved from the central Spanish government to the autonomous communities. Exactly which powers and to what extent varies according the autonomous community, and is formalised in each autonomous community's Estatuto de autonomía (statute of autonomy).
Each Estatuto de Autonomía has to be approved by a Ley Orgánica from the central Spanish Parliament. The Tribunal Constitucional is the final authority in case of uncertainty as to where the line between the Spanish Constitution and an Estatuto de Autonomía should be drawn.
The Tribunal constitucional, Spain's constitutional court is not considered part of the court system but an independent institution. It is the supreme interpreter of the Constitution, and final defender of human and civil rights.
Its decisions - jurisprudencia constitucional - control the validity of legislation. It issues sentencia, autos and declaraciones, all of which can be found in the Boletín Oficial del Estado (BOE, the official gazette). The BOE can be cited in the following manner:
