In this work, I present some data and analysis of ethnographic research that made up part of my doctoral thesis in Sociology and make up part of my current postdoctoral research, in the judicial forum of a municipality in the interior of the State of Minas Gerais. The objective is to demonstrate how the Jury Court can construct extralegal, or illegal, decisions that are contrary to the jurors' understanding due to certain practices of the agents who work there and through extralegal agreements, relativizing the juridical discourse of the jury's verdict. To this end, I describe how some practices in this field build certain filters and different institutional representations about the homicide category and the forms of judicial decision, and how it can influence the outcome of these criminal cases.
