For this reason, it is imperative to study how this procedural institution should focus in light of the Law and the Political Constitution and to evaluate its legitimacy; in addition, if the guarantee of contradiction is fulfilled or not in such a way that it allows material access to justice of all the parties and interested in the criminal process. All this be warned, in order to build a just sentence that meets the purposes of criminal law and punishment and, naturally, that is not the result of renouncing the material truth.
