I read the email. Fact is that the rulebook hasn't changed. Fact is that a contestant was allowed to use it.

In legal terms that's called a precedent. So if I were to turn up with a vector steering nose and they would prohibit me from flying, then they woud have to take out Bernd of the 2009 scores as well.

Their standpoint on this won't hold up legally. And it does have to.

So either they take Bernd out of the 2009 scores, or they change the rulebook stating specifically that it's not allowed, or it's still allowed, as it was in 2009. No matter what they say.

You can't allow something one year and then forbid it the next, if the rulebook is still the same.
