Cagliari have moved off the bottom of the Serie A table on Wednesday after the Sardinian side won an appeal over three points deducted because of a legal wrangle.
The Italian Football Federation (FIGC) docked the points earlier this month after the club took unauthorised legal action against a former player for alleged defamation in February 2007.
"The Federal Court of Justice has returned the three penalty points to Cagliari," read a note on the club's official website.
In Italy professional football figures cannot take legal action against another member without express permission from the FIGC.
Gianluca Grassadonia, now at Salernitana, suggested Cagliari had close ties with the more violent elements of the fanbase and had used these hooligans to help push him out of the club.
President Massimo Cellino decided to take legal action and the successful appeal means that the Rossoblu are now joint third from bottom alongside Livorno with 28 points from 30 games.
Davide Ballardini's side, who have won four of their last seven matches, welcome title-chasing Roma to the Stadio Sant'Elia on Saturday evening.
