I guess it's because they couldn't provide a fuel sample, so how do the stewards know if he completed Q1 and Q2 with the correct fuel. It's up to McLaren to prove he was using the correct fuel, and they couldn't. Also looking at the regs am I right in thinking you don't need to have sufficient fuel to return to the pits and also have a 1 litre sample, you just need to stop before you burn into that last litre of fuel. I just noticed it is Sam Michael who is in charge of this area in McLaren. No surprise at this stuff up then, he ruined Williams, now that he is gone they are on the comeback! Aussie or not I can't see how he is given such opportunities. I'm sure Mark Webber will never want him in his team again
