In this study, we analyse in detail Decision 20/2014 of the Slovak Constitutional Court, which examined the constitutionality of certain provisions of the Act on Land Acquisition. In this decision, the Constitutional Court addressed the constitutionality of the rules governing the transfer of ownership of agricultural land by sale. In addition to analysing the Constitutional Court's decision, the study discusses the background to the initiation of the Constitutional Court proceedings, the aftermath of the Court's decision, and the 2017 amendment to the Slovak Constitution, which is closely related to the topic under review.
