composition is now provided for in the Constitution of 1975/1985/2001 (article 95), the Law 170/1973 (as revised) and the Presidential Decree 18/1989. Administrative competence The administrative competence of the Council, as one of the three Big Bodies of the Public Administration (the other two are the Chamber of Accounts and the Hellenic Legal Council) is regulated by the article 95 of the Constitution of 1974/1985/2001 and consists in the elaboration of all the regulative decrees, namely of all the decrees that include impersonal (nor referring to a particular person) legal rules.

Its decision includes a judgement about legality and not a control upon the merits. the writ of certiorari () against the decisions of the lower administrative courts (Administrative Courts of First Instance and Administrative Courts of Appeals), which judge recourses () and their decisions include a control upon the merits.
