That's nonsense, you can apply that to anyone ever. The fuel sample is taken at the end, only. There's no reason to think that he was running any other amount at any other time, or that anyone else is, has or does. It's not checked. Further, the reason he was underweight is known - an error in fueling before the final run.
It's another bad ruling by the FIA; coming on top of a long history of bad rulings. It adds to the general picture that they're really not fit to run the sport. If there was a specific rule in place that required them to exclude him that would require a new look at the rules, but I know of no such rule. In fact, I'm pretty sure they have some degree of discretion in such cases based on how they've acted previously. So, instead, what you have is an organisation making yet another poor decision and applying a penalty well in excess of what is a reasonable response to the offence.
Are McLaren in error? Yes. Did Hamilton deserve a material penalty (as opposed to, say, a fine levelled at McLaren)? Perhaps. Did he deserve to be put to the back of the grid when he'd got to the final qualifying session fair and square, and already set a time putting him 5th? No. He didn't. That was completely over the top.
In any case, I suspect we're not going to agree over this, and I can't see that either of us are saying new instead of retreading the same set of points so this will be my last word on the matter in this thread. You, and others, can agree or disagree with me at your leisure
