 The Statute of Autonomy is the basic institutional law of the autonomous community or city, recognized by the Spanish constitution in article 147.It is approved by a parliamentary assembly representing the community, and then approved by the Cortes Generales, the Spanish Parliament, through an "Organic Law", requiring the favourable vote of the absolute majority of the Congress of Deputies.For communities that acceded to autonomy through the "fast route", a referendum is required before it can be sanctioned by the Parliament.
