Olympic champion Caster Semenya appealed to Switzerland’s Supreme Court Wednesday against the International Association of Athletics Federations' new rule requiring middle-distance female runners with high natural levels of testosterone to use medication to lower their levels.
Why it matters: Semenya was to compete at the world championships in Doha in the 800 meters event this September, but the rule would prevent her because of her testosterone level. "I am a woman and I am a world-class athlete," she said in a statement, per Reuters. "The IAAF will not drug me or stop me from being who I am."
