Poor old Macca. No wonder Ron didn't bother showing his face. If anyone else other than Ferrari had benefitted from this decision I'd be defending it, but as it is it's just another piece of evidence in the "The FIA are bias towards Ferrari" argument.
The most peculiar part is that the FIA have justified calling it inadmissable purely because no one questioned whether a similar case resulting in a turn over last year for Luizzi was admissable or not, and therefore it wasn't actually setting a precedent.
It's paragraph 27 of the court transcript, if anyone can be arsed, but suffice to say it's hilarious.
