The thesis gives an overview of the drafting of the unified Yugoslav 1929 Code of Court Procedure in Civil Litigations. Created in the unstable political and social conditions that, along with expressed legal particularism, characterized the development of the Kingdom of SCS (1918 – 1929), the Code was considered one of the cohesive factors of Yugoslav society. A propos of the unification of laws, the proclaimed parliamentarism already experienced a kind of degradation in 1921, because the Vidovdan Constitution de facto left the adoption of unified laws to the Legislative Committee, and left the National Assembly only the option of roll call voting about proposals. Some unified laws, however, were adopted only after the promulgation of the so-called 6 January dictatorship in 1929, when the primacy of the monarchist system was formally confirmed. In addition to the fact that frequent conflicts and political changes of government slowed down the adoption of the Code, the drafting process showed the existence of two different legal systems. The Serbian Code of 1865 was based on the principles inherent in the Serbian legal tradition, which Serbian lawyers wanted to preserve. For example, the most discussed question was the prohibition of proving contentious facts using witnesses in litigations in which the value of the subject matter of dispute exceeds 2 000 dinars. On the other hand, lawyers from other parts of the monarchy tended to adopt the principles from the Austrian Code of Civil Procedure of 1895. Its creator, Professor Franz Klein, observing litigation as an institution of public good, invented a procedure in which a judge manages litigation for the purpose of searching for the material truth, which is contrary to the party´s management of litigation that prevailed in the laws of the 19th century. The Austrian model of the management of the litigation in practice contributed to a faster, easier and inexpensive procedure and was later adopted by many laws, including the 1929 Yugoslav one. For these reasons, in addition to the process of drafting the Code and the polemics surrounding certain institutes, a special reference was put on Klein's new procedural model as well.
