 The autonomic agreements of 1982 and 1992 tried to equalize powers (competences) devolved to the 17 autonomous communities, within the limits of the constitution and the differences guaranteed by it.This has led to an "asymmetrical homogeneity".In the words of the Constitutional Court of Spain in its ruling of August 5, 1983, the autonomous communities are characterized by their "homogeneity and diversity...equal in their subordination to the constitutional order, in the principles of their representation in the Senate, in their legitimation before the Constitutional Court, and in that the differences between the distinct Statutes [of Autonomy] cannot imply economic or social privileges; however, they can be unequal with respect to the process to accede to autonomy and the concrete determination of the autonomic content of their Statute, and therefore, in their scope of competences.
