In legal practice, argumentation using precedents is conducted in the form of applying precedents, limiting or supplementing precedents, or not applying them. From the beginning, the Constitutional Court has developed precedent-based reasoning by explaining the gist of prior decisions and determining whether or not it is necessary to change the reasons in the current case. Because of this, the precedents of the Constitutional Court go beyond their meaning and function as pre-determining decisions and have the argumentative power as a precedent in a later case. The Constitutional Court bears a burden of argumentation when applying or departing from a precedent. Nevertheless, when examining decisions, the Court simply lists the precedents chronologically, without presenting convincing grounds for applying, modifying, or changing the precedents. Even in the case of overruling the precedent, the reasons for it are not sufficiently explained in the decision. Therefore, this article analyzed the precedent-based reasoning of the Court, identified the current status and problems, and suggested improvement plans for constitutional practice by referring to domestic and foreign-related studies.
