The FIA statement, just copied off the ITV F1 website:
' Hamilton was deemed to have "cut the chicane and gained an advantage", thereby breaching Article 30.3(a) of the sporting regulations and Appendix L chapter 4 Article 2 (g) of the International Sporting Code.'
Presumably the stewards were watching another race (perhaps a video game provided by Ferrari in their hospitality suite
, because it was clear that Hamilton immediately paused to let Raikkonen repass him. To do this Lewis must have lifted off the throttle, whereas Kimi would have been accelerating hard (or as hard as he dare in the conditions) as soon as he exited the corner.
Lewis's subsequent overtaking was therefore the result of superior acceleration and traction, rather than creating an unfair advantage for himself. He is simply a better driver, in a better car, in the wet - as was demonstrated shortly afterwards by Raikkonen losing control and crashing out.
This is an utterly absurd decision, and the fact that it has been taken under the 'Sporting Code' is a tragic irony, if there can be such a thing.
I'm not sure if McLaren can appeal, but it would probably be futile given the clear Ferrari bias in the FIA. Unfortunately taking the moral victory in F1 counts for nothing.
