In the statutes there is a need content, determined by the Constitution concerning the internal organization of the region (Council, Executive Committee, Chairman), the regional legislation than the state has its own characteristics, is territorially circumscribed, and may be exercised only on the materials to attributed to it.

According to a meaning also followed the principle in the case law indicates that any measure is an expression of a power given to the administration of a specific rule. In this sense, however, you do not have a formulation of the Constitution provides that yes, a series of law relating to reserves, the administration, but does not contain any general content to reserve for it. Finally, the rule of law is understood in the sense that must be provided by a standard measures of the law affecting unilaterally and third imperative of subjective situations (Cases scalers and other restrictive of the rights of individuals) according to legal reservation under Article.
