Sprinter loses appeal on doping ban

London -- Disgraced London-based sprinter Dwain Chambers, accused of doping, lost his appeal Friday to compete in the Beijing Olympic games.

Chambers, a 100 meters specialist, was accused of violating the British Olympic Association's bylaw, which institutes a lifetime ban on any athletes accused of doping.

He claimed that the ban represented a restraint of trade and Friday's attempt to overturn the BOA rule was denied by high court Judge Colin Mckay in London.

Chambers, who won the 100 meters sprint at last Saturday's British trials in 10 seconds, finished a two-year ban in 2006.

Three years earlier, he tested positive for the designed drug THG.

A second appeal is unlikely because the International Olympic Committee's deadline for submitting team rosters is this weekend.

"Many people would see this bylaw as unlawful," Mckay told the BBC. "In my judgment it would take a much better case than the claimant has presented to persuade me to overturn the status quo at this stage and compel his selection."
