Milan and Fiorentina have both failed in their appeals to reduce their punishment for match fixing in a court of conciliation.
Both Serie A sides had been hoping to overturn points deductions imposed during the high-profile trial in discussions with the Italian Football Federation.
However no agreement could be reached in front of the Italian Olympic Committee (CONI) and now the scandal-hit clubs will take their cases to a court of arbitration.
Milan were deducted eight points, with Fiorentina hit harder with a 19 point penalty, but both did succeed in having secondary sanctions suspended which included a one match stadium ban and a fine.
Rossoneri lawyer Leandro Cantamessa admitted he understood the stance taken by the FIGC, even if the club did not agree with it.
"We asked to leave the penalty points but an agreement hasn't been found," Cantamessa told the club's official website.
"I understand the Federation's point of view, I don't agree but I understand.
"If I had to rate this day from one to ten I would say seven, but a conciliation would have been better.
"The time for the arbitration? There is the need of 20 days."
Both clubs have ruled out the possibility of following Juventus' example and taking their cases to civil courts, a move which has threatened to bring further sanctions upon the Turin side.
The start of the Italian season could also be further delayed by Juve's actions, with the campaign already put back two weeks until September 10.
