Until 2007, all elections in the Republic of Croatia were conducted exclusively by ad hoc election bodies, including the highestelection administration body, the State Election Commission of the Republic of Croatia. In addition to the State Election Commission of the Republic of Croatia, the hierarchy of Croatian election administration bodies includes, depending on the level and type of elections, election commissions of constituencies, county, city and municipal commissions and polling stations. A significant legislative shift in the development of the election administration in Croatia occurred with the entry into force of the Law on the State Election Commission of the Republic of Croatia in 2006. The establishment of the State Election Commission of the Republic of Croatia as a permanent and independentstatebody in March2007 followsthe guidelines of the Code of Good Governance in Electoral Mattersadopted by the Council of Europe for Democracy through Law, better known as the Venice Commission. Although the State Election Commission of the Republic of Croatia is a permanent body, three of its nine members are still judges of the Supreme Court, whose president is also the president ofthe State Election Commission. All lower election administration bodies remain ad hoc bodies, and the key challenges in the future are to increase the election administration, professionalize lower-level election commissions and adopt a unified election code.
