The IAAF has filed appeals to the Court of Arbitration for Sport (CAS) against two decisions taken by the Spanish Athletics Federation.

The Spanish governing body exonerated athlete Josephine Onyia of any doping violation after adverse analytical findings following an event in Lausanne on September 2 and after she tested positive for an anabolic agent in Stuttgart on September 13.

The IAAF have asked CAS to impose a two-year suspension on the athlete.
