I'm not immediately
sure how the Court of Appeal "treatment" will help in forwarding either teams' case. Sure, in theory it buys time to investigate, but my first impression is that this plays mainly in the hands of Coughlan and Stepney (whether they have done something improper or not) ... they get a month or so to hear out both teams' "offers" and whichever has the better "deal" to put forward they will side with unless they have a waterproof defence already. Perhaps this is a bit cynical, but this was my first thought. Not a the best way to get to the "truth", I can only surmise.
I'm also less than sure whether Ferrari really wanted to go into the FIA Court of Appeal anyway, despite the "correspondence" between Mosley and Macaluso. Ferrari certainly didn't request it themselves, and are engaged in legal proceedings both in Italy and UK, and neither case will propably end before the Court of Appeal convenes to re-hear the teams. If Ferrari discontinues either civil/criminal (which are they anyway?) case before the CoA thingy, though, it propably means that the team has reached an agreement with the defendant of that case to side with Ferrari in a significant and meaningful way. Or that there's absolutely no evidence of impropriety, which would then be demonstrated by CoA upholding WMSC's decision.
I've read both that the CoA tends to impose draconian penalties and also that the CoA hasn't usually altered WMSC decisions. I haven't really followed that "part" of the sport very closely so I can only guess which one comes closer to the actual record. The latter comes from sources that have usually proved trustworthy later on, so in a way the intention of going through the process might just be to appease Ferrari without really changing the outcome.
I'm starting to think the best "punishment" for this bunch is something creative, like forcing them to work together on confidence building measures that'd benefit the whole sport with a set deadline. And if they don't present an acceptable outcome, they would both face a punishment with a little more bite ...
