Seven members of the US women's 2000 Olympic 4x100 and 4x400 metres relay teams can keep their medals from the Sydney Games.
The Court of Arbitration for Sport ruling overturned a 2008 International Olympic Committee decision to strip the athletes of their medals after relay team member Marion Jones admitted she had used a banned substance during the Games.
The US 4x100 team won bronze and the 4x400 team gold at the Sydney Summer Games.
