A ruling expected this week by the highest chamber of the European Court of Human Rights could reignite champion runner Caster Semenya's yearslong legal battle against sports authorities over sex eligibility rules that banned her and other women from top events including the Olympics and world championships.
If a panel of judges upholds a 2023 decision by the same court in Semenya's favor, it would put renewed scrutiny on track and field's rules requiring some female athletes to suppress their natural testosterone levels in order to compete — and open a legal avenue for the regulations to be struck down.
