According to the article quoted by @Tanu_Mz on the previous page:
"The original case, in 2006, was rushed through the FIGC’s court of sporting justice in order to close the proceedings in time for the World Cup and avoid sanctions from FIFA. Juventus, in fact, did not appeal the guilty verdict they were slapped with, as to have an ongoing open investigation within their league would have meant Italy being banned from competing in the World Cup that summer, a tournament that the Azzurri eventually won."
I don't know how events would've unfolded if Juve appealed but this may have been a factor in that decision, if true of course.
@Hustini, I am sorry but it will take many years still until Juve are truly back where they were back then. Yes, Juve may be dominating in Serie A again but just take a look at the enormous financial gap that has opened up between them and Europe's richest clubs. Reaching the former level of competitiveness and global appeal will not happen that quickly.
