Sports proceedings began soon after Calciopoli, an association football scandal, was made public in May 2006. In July 2006, the Italian Football Federation's (FIGC) Federal Court of Justice started the sports trial. Juventus was relegated to Serie B with points-deduction, while other clubs (Arezzo, Fiorentina, Lazio, Milan, Pescara, Reggina, Siena, and Triestina) only received points deductions. Most of implicated club's presidents and executives, as well as referees, referee designators, referee assistants, and FIGC higher-ups were initially proposed to be banned for life but only Juventus CEO Antonio Giraudo and Juventus general director Luciano Moggi were confirmed to be banned for life. Two criminal trials took place in Naples, the first related to Calciopoli proper, while the second involved consultancy company GEA World, which was alleged to hold power over all transfers and Italian football players and agents; all defendants were acquitted of the stronger charges. The Naples trial resulted in Calciopoli bis, which implicated almost every Serie A club, including Inter Milan, to which it was awarded the 2006 scudetto. Moggi's legal defence attempted to present those new developments at the Naples court but they were refused because the court ruled that it was there to determinate whether Moggi's lifetime ban should be confirmed and the gravity of his actions, as was sentenced in the controversial 2006 sports trial.
The Naples trial much reduced Moggi's power and that of his charged criminal association (la Cupola, literally "the Dome"); nonetheless, based on the 2006 sports trial, the Naples Court of Appeal confirmed Moggi and Giraudo's lifetime ban, and Moggi's criminal association charge. In 2015, the Supreme Court ruled in its final resolution that Moggi was acquitted of "some individual charges for sports fraud, but not from being the 'promoter' of the 'criminal conspiracy' that culminated in Calciopoli", although there were only 6 convictions (including Moggi and Giraudo) out of the initial 37 defendants; Massimo De Santis was the only referee to be convicted, while the other five's charges were annulled because of the statute of limitations. In 2018, the Supreme Court rejected Juventus's appeal, ending the dispute in the ordinary justice system. In 2020, the CONI's College of Guarantee declared the latest Juventus's appeal to not be admissible, also exhausting all the levels of judgment, and ending the dispute in the sports justice system. Both Moggi and Giraudo appealed to the European Court of Human Rights for the conduct of the trials, which remain a debated and controversial topic.
