What you can't appeal is a drive through.
The Speed commentators are as uninformed as ever. The WMSC did find Ferrari guilty...
"Having heard extensive detailed evidence, the Judging Body of the WMSC was satisfied that team orders were issued...and as such was contrary to article 39.1 of the sporting regulations."
...
"This clearly interfered with the results of the race, and...was in the Judging Body of the WMSC's view prejudicial to the interest of motor sport and contrary to article 151(c) of the ISC."
The WMSC's investigator recommended they maintain the fine, issue a 5 second penalty to Alonso to restore the result of the race, and to withdraw all the team's and drivers' points for the season (suspended, provided they didn't do it again).
That seems to me like a very fair judgement, since all Ferrari would have lost is what they'd gained through cheating. The WMSC's logic for not following through on their own recommendation is, imo, quite flawed.
