In particular, it focuses on the legal significance of the Supreme Court judgment of 5 October 2012 (IV CSK 244/12), which ruled that such an agreement cannot be regarded as a  lease. The author seeks to identify the possible practical consequences of this judgment and propose legislative measures to ensure the sustainability of such agreements, and thus the investments which go with them as well as to analyze the legal term fructus in the civil law in the context of this judgment.plrenewable energywind farmsleasefructusArtykuł
