Specifičnost nadzora nad radom izvršnih i upravnih tijela lokalne samouprave leži u opreci između upravnih obilježja jedinice lokalne samouprave i njezinih samoupravnih obilježja. Stoga on treba biti ustrojen na način kojim se respektiraju samoupravne ovlasti lokalne samouprave, ali pritom istodobno štiti zakonitost u cjelokupnom pravnom sustavu. U radu se istražuju oblici nadzora nad izvršnim i upravnim tijelima jedinica lokalne samouprave u Hrvatskoj, pri čemu se, nakon razmatranja prirode nadzora, subjekata nadzora i nadzornih ovlasti, posebice analizira nadzor unutar samih tijela lokalne samouprave, hijerarhijski upravni nadzor od strane tijela područne (regionalne) samouprave te upravni i inspekcijski nadzor od strane Ministarstva uprave, upravnosudski nadzor kao i nadzor od strane pučkoga pravobranitelja. Poseban naglasak stavljen je na instrumente provođenja svakoga pojedinoga nadzora te na nadzorne ovlasti kojima raspolažu nadzorna tijela. Pritom se skreće pozornost na utjecaj koji na učinkovitost i djelotvornost nadzora imaju broj i veličina lokalnih jedinica i posljedično njihova objektivna sposobnost obavljanja poslova iz samoupravnog djelokruga. The specificity of supervision over the work of executive and administrative bodies of local self-government lies in the contradiction between administrative characteristics of units of local self-government and its self-administrative characteristics. Therefore, it should be organised in a way that respects the self-administration powers of local self-government, but at the same time, protects legality in the entire legal system. This paper investigates the supervision of executive and administrative bodies of units of local self-government in Croatia. Here, after considering the nature of the supervision, subjects of supervision and supervisory powers, in particular the forms of supervision are analysed over executive and administrative bodies of units of local self-government, hierarchical administrative supervision by bodies of regional self-government and administrative and inspectorial supervision by the Ministry of Administration, administrative court supervision as well as supervision by the ombudsman. Particular emphasis is placed on the instruments for implementation of every individual supervision and on the supervisory powers at the disposal of supervisory bodies. Thereby attention is given to the influence on the efficiency and effectiveness of supervision, the number and size of local units and consequently their objective capability to carry out duties within the sphere of self-government.
