This article examines specific issues surrounding the presumption of legality in judicial decisions. Noting the possibility of refuting this presumption, the author analyzes its inherent stability. Drawing on judicial statistics, he concludes that legality arises automatically and remains unchanged (judicial decisions are generally not appealed, and if appealed, they are often upheld). Emphasizing the relatively high quality of justice and the reliability of the presumption of legality, the author draws attention to the need to maintain the professionalism of judges and their competitive selection, as well as to ensure the legality of decisions that have not been reviewed by higher courts.
