The Republic of Croatia is organized into 127 cities, 428 municipalities and 20 counties. Cities and municipalities are units of local self-government, whereas counties are units of regional self-government. Units of local and regional self-government are responsible for performing activities determined by the applicable laws of the Republic of Croatia, in particular activities stipulated under the Local and Regional Self-Government Act. Local and regional self-government units make decisions regarding many rights, obligations and legal interests of natural and legal persons, as well as decisions on other matters of interest for a particular self-government unit. Local and regional self-government units perform activities falling under their competence through adopting acts of general application and acts of specific application. Moreover, acts of general application, more precisely statutes and rules of procedure, are used for the purpose of establishing internal organisation of representative and executive bodies of such units. Acts of general application are adopted by representative bodies, and they include: statutes, rules of procedure, decisions, ordinances, programmes and plans, as well as budgets. Acts of specific application, on the other hand, are adopted by executive and administrative bodies and they include: rulings, decisions and conclusions. To ensure compliance with the principles of constitutionality and lawfulness, central state administration bodies supervise the lawfulness of general-application acts, whereas the High Administrative Court supervises the lawfulness of specific-application acts adopted by units of local and regional self-government.
