This article is trying to show that the cause of the crisis of inclusive development of civil society in Poland is that there are different decisions being rendered based on the same regulations, which prejudge inequality before the law, lead to violation of human rights and standards, and impede participation in social and economic life. In legal sciences, the issue of elaborating criteria for resolving doubts about the content of the law is almost never undertaken, and they are not subject to legal regulation and can only be established spontaneously as a law. With regard to the spontaneous creation of law, scientific research is practically not carried out, which makes it difficult to determine exactly what rules, principles, guidelines for interpretation and application of law apply. Because of the foregoing, the basic conditions for inclusive development are not guaranteed. The explanation of this problem is a novelty from the point of view of the causes of the crisis of a given development and causes of the crisis of the legal system. The article uses the method of linguistic analysis and economic analysis of law.
