British sprinter Dwain Chambers failed in his court bid Friday to overturn a lifetime Olympics ban so that he could run in next month's Games in Beijing, reported dpa.
The British Olympic Association (BOA) banned the 30-year-old from competing at future Games after he tested positive for the steroid THG in 2003, for which Chambers has already served a two-year suspension.
The sprinter qualified to compete in Beijing by winning the 100 metres at the Olympic athletics trials in Birmingham last Saturday in a time of 10.00 seconds.
As a result, Chambers took a case against the BOA by-law, arguing that it was an unfair restraint of trade but his attempt to secure an injunction at the High Court failed.
