Perhaps You Were Wondering?

I know I was.
Phonak's Robbie Hunter, a South African, was eliminated from the Tour de France after the penultimate stage for missing the time cut. He crossed the line 18:09 -- one minute and 11 seconds outside the permitted time limit.
He later explained to a friend in a text message: "I rode the whole time trial standing because of saddle sores. My arse is in pieces. What a way to end the Tour."
Hunter traveled to Paris from the time trial finish at Montceau-les Mines, but was not permitted to travel with the Tour peloton on a chartered TGV fast train because his elimination means he is no longer an official member of the Tour.
I guess that goes for Tom Boonen, too?
Who makes up these rules?
Hunter won Stage 1 of the Tour of Georgia earlier this year. A sprinter, became the first South African to finish the Tour in 2002. Now we know why he didn't finish in 2006.
