Summary The paper is dedicated to the argument of common sense in judicial practice, on the basis of which the Constitutional Court annuls judgments and decisions of administrative courts in order to protect the rule of law and the constitutional rights of individuals. The paper presents the protection of individual rights and legal interests through the protection before administrative courts, the Constitutional Court and the European Court of Human Rights. Attention is devoted to defining the administrative dispute as an important branch of litigation in which the importance of applying the argument of common sense is particularly emphasized. Also, the paper elaborates on the issue of correct and complete determination of the factual situation and interpretation and correct application of substantive law to a concrete social relationship, without which the courts cannot make fair decisions, i.e. verdicts and rulings. The argument of common sense has taken root in constitutional judicial practice, given that legal rules must not be mechanically applied to concrete life situations, and it is necessary to consider the context in each individual case. Constitutional decisions based on the argument of common sense as a protection of the objective legal order are cited, as well as the practice of administrative courts that refer to the decisions of the Constitutional Court when deciding on a specific issue. The conclusion briefly presents all the presented facts about judicial supervision of public administration, the protection of human rights and fundamental freedoms, i.e. the adoption of a legal decision and the realization of a guarantee of judicial control of the legality of individual acts of administrative authorities and bodies that have public powers, and the importance of a uniform interpretation of judicial practice.
