The European Court of Human Rights (ECHR) has ruled in favor of Caster Semenya, stating that the South African runner did not receive a fair trial when challenging regulations requiring her to lower testosterone levels to compete in women's athletics. Semenya, a two-time Olympic gold medalist, has been embroiled in a lengthy legal battle against these rules. Following the ECHR's decision, Semenya has called for greater protection of athletes' rights. The ruling marks a significant development in the ongoing debate surrounding eligibility criteria for transgender and intersex athletes in sports.
