Nino Di Matteo, a well-known anti-mafia prosecutor and current member of the CSM, has been vocal about the detrimental effects of factionalism ('correntismo') within the Italian judiciary. He emphasized that being part of a faction is often essential for career advancement and protection against isolation, likening this practice to mafia methods. Di Matteo made these remarks during his candidacy speeches and various media appearances, illustrating the ongoing struggle against corruption and influence in judicial appointments.

His critiques reflect a broader concern regarding how factional alliances can undermine the integrity of judicial decisions in Italy. Di Matteo's statements from September 2019 and October 2020 point to a persistent problem where career progression within the judicial system is influenced by allegiance to specific groups rather than merit. This raises significant ethical questions about the current appointment processes for judges and prosecutors in Italy, reflecting a justice system that may be compromised by loyalty to factions rather than a commitment to impartiality.

The implications of Di Matteo's warnings are profound, as they highlight systemic issues within the Italian judiciary that could erode public trust in the legal system. The response from political entities and judicial organizations, including the left and the ANM (National Magistrates Association), could shape future reforms aimed at mitigating such influences. As these discussions unfold, the focus remains on ensuring that judicial appointments are fair and based on the principles of justice rather than factional loyalty, a reform crucial for maintaining the rule of law in Italy.
