I think Toto will pursue it beyond this current appeal against the stewards' decision, and take it to the court of arbitration. He knows the Driver's Championship gong won't be going Hammy's way, but he has a number of points to make to the FIA.
First, that Masi did in fact break the sporting regs as written. That his application of the rules was vacillating, arbitrary, rushed and contrived. That the stewards' dismissal of Mercedes' protest was peremptory - they failed to address the substance of the protest. That they waved it away by creating and sustaining a gross overreach of the sporting director's powers - in effect that Masi can break, bend, adapt or apply any regulation he sees fit when he chooses to, and that flagrant errors of judgement can be post facto justified either by citing the race director's omnipotence, or by claiming his hands were tied by the incorrect decision .
Toto probably believes that the current standard of race governance is ill-suited for the business of Formula One, and that a new regime needs to be designed, trained and implemented before next season. The only way to make that happen is to make it painful for the FIA. Part of his case will be that Mercedes has little confidence in the judgement and capability of Michael Masi. Toto will want to see Mr Masi out of the race control room, or at least surrounded by additional resource so he doesn't get so flustered and panicky.
At the very least Toto wants some acknowledgement by the FIA that the race and season outcome was artificially contrived by the poor decisions of its race director, who was manifestly influenced by Red Bull. In short, the FIA needs to say sorry, to F1 fans, to Mercedes and to Hammy. That's what Toto wants.
The other reason Toto should see it through is to "go to the mattresses". Every once in a while, a good punch up helps to clear the air.
