A polgári döntvények jogforrási jellege és visszaható hatálya

In this paper, I will attempt to describe the creating of civil law decisions in Hungary in the period 1882-1949 from the perspective of whether these principle agreements could be considered as the sources of law, prior to the reform in 1912 and following that, regarding the form and the content. Then I consider the permissibility of their retroactive application from the point of view of legal certainty and criticise the defects in the legislation of the time. For this purpose, I will process several sources of legal literature and legal sources concerning the law of decisions of the civil era, as well as judgments of individual cases.
