Caster Semenya - Man eller kvinna?

Sydafrikanska friidrottsstjärnan Caster Semenya får rätt i Europadomstolen.

Nu kan idrottens skiljedomstol, Cas, tvingas ändra reglerna kring testosteronhalter.

In a statement soon after the European rights court's decision was published, World Athletics showed no sign of budging and said its rules would "remain in place."

"We remain of the view that the ... regulations are a necessary, reasonable and proportionate means of protecting fair competition in the female category as the Court of Arbitration for Sport and Swiss Federal Tribunal both found," World Athletics said.

World Athletics also said it would be "encouraging" the government of Switzerland to appeal the ruling.

In the case of Semenya v. Switzerland the Court held that there had been a violation of the right to a fair hearing.

The case concerned an international-level athlete, specialising in middle-distance races, who complained about certain regulations of the International Association of Athletics Federations (IAAF – now called World Athletics) requiring her to take hormone treatment to decrease her natural testosterone level in order to be able to take part in international competitions in the female category. Having refused to undergo the treatment, she was no longer able to take part in international competitions.
