The Grand Chamber of the European Court of Human Rights has upheld a 2023 ruling that Caster Semenya's appeal to a Swiss Federal Tribunal against World Athletics regulations that barred her from competing, had not been properly heard. The two-time 800-metre Olympic Games gold medalist is appealing the regulation that female athletes with differences in sexual development, medically reduce their testosterone levels. The verdict of the Grand Chamber, however, does not set aside these rules, but it keeps Semenya's legal challenge alive. Sakina Kamwendo spoke to SABC's Janet Whitton
