Mullings life ban upheld
The Court of Arbitration for Sport has upheld the life ban imposed on Jamaican sprinter Steve Mullings.
Mullings' ban followed a second positive drugs test in 2011.
The 30-year-old Mullings, a member of the 4x100m relay teams that won gold at the 2009 world championships and silver in 2007 alongside Usain Bolt and Asafa Powell, tested positive for Furosemide in 2011 and was subsequently banned for life by the Jamaican Anti-Doping Commission.
Earlier in his career he had served a two-year suspension after testing positive for methyltestosterone in 2004, and Mullings appealed to CAS against the life ban arguing irregularities with the 2004 results.
In a statement CAS said: "While Mullings has attempted to raise suspicion about his first violation, the CAS Panel did not find that the circumstances surrounding the first offence did warrant a more lenient sanction and, accordingly, it confirmed the lifetime ban."
