The Legal Clinic on Criminal Mediation is one of the latest innovations in the wide range of clinical training courses developed over the years by the Department of Law of the Roma Tre University. The training objective of the Clinic, in the part dedicated to criminal matters, is to provide students with theoretical-practical knowledge of the tools necessary for the use of the new restorative justice modules which, especially in light of the latest criminal trial reform, approved by Legislative Decree no. 150 of 2022, are assuming considerable importance in the management of criminal litigation. In this perspective, students who attend clinical activities are asked to study and discuss real cases initiated by a process of mediation-reparation between the victim and the person indicated as the perpetrator of the crime, with the help of expert professionals in the field of Justice Reparative. The portion of the entire course dedicated to criminal mediation is eight lessons of two hours each.
