Knox was accused of falsely implicating Lumumba and charged with calunnia (slander), which under Italian law is knowingly blaming someone for a crime they didn't commit. In 2011, Judge Claudio Pratillo Hellman gave Knox a three-year sentence (which it was ruled she had already served), as well as ordered her to pay Lumumba's 22,000-Euro court costs. (As of 2015, Knox has not paid Lumumba, who was incarcerated for two weeks for Kercher's murder before being exonerated, whose bar faltered in the wake of the negative publicity he received, and who consequently moved to Poland, the homeland of his wife Alexandra Beata.[73] The Italian state also later awarded Lumumba 8,000 Euros in damages, but he rejected this to pursue a claim through the European Court of Human Rights.[74][75][76][77])

In 1989, Italy reformed its inquisitorial system, introducing elements of U.S.-style adversarial procedure. The changes were intended to remove an inquisitorial continuity between the investigatory phase and the basis for a decision at trial, but in practice they took control of inquiries away from police and gave prosecutors authority over the preliminary investigation.[63][64][65] Although they have considerable authority over early inquiries and discretion in bringing charges, Italian prosecutors do not customarily use their powers in the aggressive way common in the US system.[13][66] ...
According to a scholar who researched comparative law in Italy, selective changes to the Italian legal system left it unable to cope when a prosecutor with Mignini's American-style adversarial approach used his powers to the fullest.[13]
