No one is going to Serie B nor will anyone get a point deduction.
If Moratti is found to be involved (like that is new or something) he can be suspended or expelled from Italian soccer, fined, etc. He can wind up charged for defamation etc.
The FIGC can be fined and figures that allowed the unlawful trial can be suspended and so on.
Sending Inter to Serie B isn't part of it. Not only is this not a sporting trial but it has nothing to do with on field cheating. The trial will be overturned and Juve will get a shit load of cash from the responsible entities (Telecom, Inter, FIGC, Gazzetta, etc) in addition to its titles.
Best of all, all those black and blue cum guzzlers will have nothing left to say.
