The Court will be delivering a Grand Chamber ruling in the case of Semenya v. Switzerland on 10 July 2025.

The case concerns 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.
