Student thesis: Master's Thesis


Portuguese Criminal Procedural Law adopts a free evidence system, therefore it only prohibits means of evidence not allowed by law. Condition that reflects the nonassignment of the competent authorities to rules of assessment, as established in article 127 of the Criminal Procedure Code. In the practice of criminal proceedings, entities apprise the statements of procedural participants which implies knowing how to detect truthfulness and lies. This exigency to understand the psychological aspect of the deponent, which does not prescind of a coherent foundation, relates with the branch of psychology, which has been developing several studies in this sphere. Turns out that the courts, for some years now have been using means of distance communication, and in the context of the COVID-19 pandemic, their use has increased exponentially, and the constraints decreased proportionately. This circumstance and the practical contact with imperfect computer systems, guided us to try to understand the extent to which it is not undermining the principle of free assessment of evidence, since effectiveness lacks the best production of evidence. To achieve the best results, we collected the opinion of 23 judicial operators, which we analyzed and applied to the theme.
