LAUSANNE, Switzerland - The Court of Arbitration for Sport has overturned Britain's lifetime Olympic ban for doping offenders.
Sport's highest court says the British Olympic Association's sanction is invalid because it fails to comply with the World Anti-Doping Agency code.
The CAS decision was officially released Monday.
CAS ruled that a lifetime ban from the Olympics amounts to a second sanction after an initial doping ban.
The ruling clears the way for sprinter Dwain Chambers and cyclist David Millar, who were banned for doping offences, to try to compete for Britain at the London Olympics.
