This paper is the result of my participation in a discussion event of Prob-lema. Anuario de filosofia y teoria del derecho entitled "The Construction of Precedent in Civil Law: Debates, Concepts and Challenges". Several colleagues with a vast knowledge on the subject of judicial precedent participated in this seminar, which also delved into the widely debated aspects of judicial prec-edent focused on the case of Chile. The entire discussion aimed at proposing solutions, as well as shedding some light on some of its important aspects. Starting from such transcendental concepts as, rationality and argumen-tative use, it is possible to find certain problems arising from the improper use of the above concepts, which in turn leads us to stare decisis, a term that if used incorrectly may result in an act against the internal independence of judges.
