Who says there's no science or proof? Did they have the arbitration already?
USADA says they will release some of their evidence shortly. Let's see what they have first.
They did say they have blood data consistent with doping.
Plus you don't need a positive test to ban someone. See Marion Jones.

Landis had lost his title after a positive dope test, initially claiming innocence and then later admitting guilt. It was only at this juncture that he made doping accusations against Armstrong and others. The investigation, which by this stage included the FBI, the Department of Justice Office of Criminal Investigation, the U.S. Food and Drug Administration, and the U.S. Postal Service’s Office of Inspector General, then proceeded to take secret grand jury testimony from an unknown number of witnesses, including, members of Armstrong’s previous cycling teams who admitted to doping. It does not appear that any charges were brought against these athletes, which, says Bruce Deming former FBI investigator, raises the problem of credibility: were they promised immunity if they cooperated with the investigation of Armstrong? But even after all of this, which took two years and millions of dollars, federal prosecutors dropped the investigation on February 3, 2012.
“The reason was obvious,” says Deming. “They didn’t have enough evidence to bring a single charge. I don’t think anyone would dispute that, or the fact that summarily dropping the case was an embarrassment to those who championed the investigation, including USADA’s CEO, Travis Tygart.”
