No it's still ongoing and a few (former-) teammembers are still awaiting charges. It's just that Ferrari didn't push for "the case" at the time it came to light because they were champion anyway and well.. Toyota
This is much more serious..I wouldn't be suprised if the McLarens were "faster" throughout the last few races (or the Ferrari's slower heh) because of all this.
I think it's quite impossible to make such a performance jump like McLaren did i nsuch a short time period so it's probably fair to assume Ferrari did a huge step backwards.. this is not about copying actual bodyparts/panels/wings like Toyota did..if you look to both McLaren and Ferrari body, they are quite different.
