EDIT: I don't think it's an April Fools based on the times of the press releases such as this one today
http://www.autosport.com/news/report.php/id/74138.
This really makes no sense.
LH gets 3rd cause the Toyota falls off the track.
At this point he can just stay there and all is good.
Someone at McLaren (driver or team) decide that Trulli should be let back past, an odd decision.
Then McLaren realise they've c0cked up and given away a vital point, so fabricate a BS story to get Trulli demoted, realising that a decision given after the race is un-appealable.
Pretty underhanded so far...but then they tell the press a different story to the stewards, plain dumb!
Nothing adds up here, it's either McLaren are incredibly dumb (which I struggle to believe), or we've not got the real story. Personally I'll wait for the official story before deciding who is in the wrong. If it's true it's a dark day for LH and McLaren. LH isn't much liked in the paddock at any rate and stitching up a fellow driver would be very low.
I really hope for the sport this isn't true.
