Foggia are set to start next season in Serie C after they lost their appeal for a six-point deduction to be lifted.
Foggia had sent the appeal following Palermo’s demotion for financial irregularities.
However, CONI appeals court chief Franco Frattini ruled on Friday that the original verdict would stand.
Consequently, there will be no need for playouts, with the Rossoneri finishing a point behind Salernitana in 16th place.
Frattini also formalised the decision for promotion playoffs to go ahead, throwing out Palermo’s appeal to have them suspended.
