The Athletics Integrity Unit says it has begun the process of challenging the decision to clear Tobi Amusan of doping violations after the body charged her with three whereabouts failures in July before she was cleared by a panel in August.
Amusan who just won her third consecutive women’s 100m hurdles Diamond League title in Eugene on Sunday will now have to go through a fresh legal battle at the Court of Arbitration for Sport.
The World Champion was first provisionally suspended by the AIU in July over three whereabouts failures but the Disciplinary Tribunal ruled in favor of the world record holder two days before the World Athletics Championships in Budapest last month.
