Dwain Chambers and David Millar were cleared for the London Olympics late Thursday after the British Olympic Association officially rescinded its lifetime ban for athletes found guilty of doping offences.

The formality followed the Court of Arbitration for Sport (CAS) ruling which declared the BOA’s controversial bye-law to be in direct contravention of the World Anti-Doping Agency (WADA) code.

“Following a discussion period, during which members of the National Olympic Committee reiterated their support for the decision taken by the BOA board to defend the Eligibility Bye Law before CAS, it was agreed that the bye-law would immediately be rescinded in order for the BOA to comply with the CAS ruling,” said a BOA statement.

“The BOA will now notify WADA of this decision in writing.”

Former European 100m champion Chambers, who won 60m bronze in this year’s world indoor event in Istanbul last month, was banned for two years after testing positive for the anabolic steroid THG in 2004.

Cyclist Millar also served a doping ban in 2004.

Despite this week’s decision, Chambers and Millar will still have to meet the qualifying standards for the Olympics.
