Ključni dio ustavne nadležnosti svakog ustavnog suda predstavlja apstraktna kontrola ustavnosti zakona i drugih propisa. Prikazan je sustav ustavnosudskog nadzora ustavnosti zakona kao temeljnog jamstva oživotvorenja vladavine prava, konstitucionalizma i načela ustavnosti u formalnom i u materijalnom smislu. Rad je posvećen analizi odabranih odluka Ustavnoga suda Republike Hrvatske u nadzoru ustavnosti i zakonitosti upravnopravnih propisa, zakona i podzakonskih akata. Upravo ispunjavajući prikazanu ulogu u obavljanju zadaća iz svoje nadležnosti, Ustavni sud kao posebno tijelo državne vlasti stalno djeluje kao njegov ustavnopravni korektiv. A key segment of the constitutional jurisdiction of every constitutional court represents abstract control of the constitutionality of the law and other regulations. The system of constitutional court supervision of the constitutionality of the law is demonstrated as a fundamental guarantee to reviving rule of law, constitutionalism, and constitutional principles in a formal and substantive sense. This paper is dedicated to the analysis of certain decisions of the Constitutional Court of the Republic of Croatia in the supervision of the constitutionality and legality of administrative regulations, laws, and sublegal acts. It is precisely in fulfilling this demonstrated role of carrying out duties within its jurisdiction that the Constitutional Court, as a special body of governmental power, continuously acts as its constitutional law corrective.
