Our thesis wishes to analyze the experience of juries inside criminal justice. From various interviews made with former jurors and Presidents of criminal justice as well as observations of real court sessions, we would like to show that the practice of judgement has a disturbing effect on the jurors’ convictions. The shift occurring inside the jurors’ mind is analysed through the concept of democratic conversion. This analogy will enable us to explain the process taking place inside each juror all along their experience. Our thesis analyses this “oral system” as a process heading towards democratization. Thus, we will study the ritual of penal process, the building of the absolute conviction and the Presidents’ contribution inside the final verdict. Those elements, compared with the experience of the jurors, give us the opportunity to identify the several steps of their conversion. All of these changes are strongly linked with the importance that the jurors give to the decision they have to make. The building of their absolute conviction, analysed as a true ability to judge, is at the core of the process of democratic conversion. The experience of judgement tends to be as crucial for the jurors we’ve met as for the democracy itself.
