Abstract
For Carlos Alchourron and Eugenio Bulygin, a judicial sentence is justifiable according to law only if it contains a logical sequence of rules and the description of a case. Manuel Atienza and Juan Ruiz Manero deny the application of this theory to the legal reasoning. They assert that a different conceptual apparatus is needed that understands law as an activity where society participates and the jurist has the function of deploying it. This article examines and confronts the main theses of the authors mentioned, emphasizing characters that should not be ignored when a judicial decision is justified.
