In line with the provisions of the St. Vitus’ Day Constitution (1921), Slovenia was divided into the Ljubljana and Maribor Administrative Units. As late as in 1927, the Slovenian Administrative Unit self-governments became operational, which implied a partial mitigation of centralism. Fifteen Slovenian lawyers were elected for the Ljubljana and Maribor Administrative Unit Assemblies, the highest bodies of these two territories. By carrying out essential self-government functions, they contributed significantly to the fact that the Slovenian Administrative Unit self-governments were the most successful among all 33 in the state at implementing the tasks, crucial for the multifaceted progress of Slovenia. Lawyers in particular had merit for the developments in the regulatory field. After the unification of the Ljubljana and Maribor Administrative Units into the Drava Banate in the autumn of 1929, the Ban’s Council functioned as the Ban’s consultative body with regard to budgeting. The Ban’s Councillors were appointed by the Ministers of the Interior. In the 1930s, the Ministers also appointed 32 lawyers as representatives of cities and districts in the Ban’s Council. They were exceedingly active, especially in their efforts to expand the autonomous powers of the Ban’s Council. All of the highest officials of the general state administration in the Administrative Units and the Banate were lawyers.
