Two-time Olympic champion runner Caster Semenya won a partial victory at the European Court of Human Rights on Thursday in her seven-year legal fight against track and field’s sex eligibility rules.

The court’s 17-judge highest chamber said in a 15-2 vote that Semenya had some of her rights to a fair hearing violated at Switzerland’s Supreme Court, where she had appealed against a ruling by the Court of Arbitration for Sport.

The case between Semenya and track’s governing body  was about whether athletes like her — who have specific medical conditions, a typical male chromosome pattern and naturally high testosterone levels — should be allowed to compete freely in women’s sports.
