This work develops a proposed method for the analysis of penal sentences which allows them to be understood as a practice in discourse, and to be compared with other forms of social discourse. From a specialised corpus consisting of one hundred thirty-seven sentences handed down by Temuco Oral Tribunal in the penal area, and basing our work on van Dijk and the Grounded Theory methodology, we construct and structure to describe and model the internal organization of the decisions, facilitating the process of comparison and contrast with other discourses. The research helps to make it possible to study judicial discourse, highlighting the expectations of society which the judges consider legitimate and the practices of invisible violence which construct the idea of the delinquent as an enemy.
