L'utilizzabilità degli atti nella fase investigativa. La prova per le indagini preliminari

The doctorate’s theme of research - Abstract My doctorate’s theme of research is about the Investigation in the Italian criminal proceedings. The Italian Code of criminal procedure of 1988 is the fruit of a new ideology that marks a departure from Italy’s prior inquisitorial tradition. According to criminal procedure Code of 1988, an accusatorial system separates the investigation and trial stages and the judge’s decision is based only on evidence collected in oral form in his presence in a public trial containing adversarial dynamics. The Italian Code of 1988 created a separation between criminal investigations and trial. Investigations are conducted by Public Prosecutor: he conducts the investigation phase in order to deem whether to file a formal charge against the defendant or to dismiss the case and the investigative evidence collected should serve only for this purpose. According to so called “inutilizzabilità fisiologica”’s rule, the evidence collected during investigations by prosecutor is not usable during trial by the judge: the results of the investigative efforts displayed by the parties should be kept outside of court. If the proceedings go on to trial, the case shall be deemed with only evidence collected in front of the judge. To create the separation of the trial phase from the investigation stage, there is the double-dossier system. During the investigations, evidence are collected in an investigation dossier. The trial judge will never see the investigation dossier and the trial judge’s decision is based on a new dossier, the trial dossier, with the evidence collected during the trial. The issue of my research is about the investigation, the so called “inutilizzabilità fisiologica”’s rule and also the exclusionary rules that concern the investigative phase and the decisions pronounced during the investigations (for example, the decisions concerning pre-trial confinement). 2 In fact, the exclusionary rule system (so called “inutilizzabilità patologica”) provides that evidence cannot be used in Italian criminal proceedings if it was the result of illegal inquiry.
