South African Olympic champion Caster Semenya is awaiting a landmark ruling this week from the Grand Chamber of the European Court of Human Rights (ECHR) that could reignite her years-long legal battle against sex eligibility rules in athletics regulations that effectively ended her career and continue to shape policies in women’s sports globally.
The highly anticipated decision, scheduled for Thursday, could either uphold or overturn the court’s 2023 finding that the rules discriminated against Semenya. Legal experts say the outcome could send ripple effects across the sporting world, reopening the debate on fairness, inclusion, and human rights in elite women’s competitions.
A Case Beyond Medals
Semenya, 34, who was assigned female at birth and has always identified as a woman, has a Differences of Sex Development (DSD) condition that results in naturally elevated testosterone levels. Once the world’s most dominant runner in the 800 meters winning two Olympic gold medals and more than 30 consecutive races her career was abruptly cut short in 2019 after she refused to comply with World Athletics regulations requiring female athletes with high testosterone to undergo hormone suppression therapy to compete.
Now a coach and advocate, Semenya says her legal battle is no longer about returning to competition, but about athlete dignity and human rights.
“It’s a battle for human rights now. It’s not about competing, it’s about putting athletes’ rights first,” Semenya told a South African newspaper.
The Stakes of the Ruling
If the Grand Chamber’s 17-judge panel upholds the 2023 ruling, it would represent a major victory for Semenya and potentially open a legal pathway to challenge or even invalidate the sex eligibility regulations imposed by World Athletics.
However, if the judges rule against her, it would most likely close the final legal door, as decisions by the Grand Chamber are final and binding, with no right to appeal.
The 2023 judgment found that Switzerland failed to provide Semenya with effective legal protection when she previously challenged the rules at the Court of Arbitration for Sport and the Swiss Supreme Court. The Grand Chamber must now determine if that ruling stands.
Global Implications for Sports Governance
World Athletics introduced the contested regulations in 2018, arguing that high natural testosterone levels in athletes like Semenya give them a “male-like advantage” over others. The rules have since been used as a template by other sports, including swimming and boxing, to create similar testosterone-based eligibility standards for female competition.
The case has also become highly politicized, with U.S. President Donald Trump and other conservative figures framing it as a threat to women’s sports. Meanwhile, athletes’ rights organizations have expressed growing concern over the physical and emotional toll of enforced medical interventions on competitors.
The International Olympic Committee (IOC), under new President Kirsty Coventry, is under pressure to standardize eligibility rules for all Olympic sports. Several federations, including FIFA and World Boxing, are currently reviewing or rewriting their policies in light of recent controversies.
A Legal First with Broad Consequences
Semenya’s legal campaign spanning courts in Switzerland, France, and multiple tribunals is considered unprecedented. Her case could set a definitive legal precedent on how human rights law applies to sports regulations, particularly those that target athletes with DSD conditions.
Even if Thursday’s verdict does not immediately nullify the rules, a decision in Semenya’s favor could send the case back to Switzerland’s courts, potentially sparking a full re-evaluation by the Court of Arbitration for Sport.
From Track Icon to Human Rights Symbol
Since stepping away from international competition, Semenya has shifted her focus to coaching and advocacy, determined to ensure that future generations of athletes are not subjected to the same restrictions she faced.
Regardless of the court’s final ruling, Semenya’s legal journey has already changed the discourse on identity, fairness, and the rights of women in sport. As the world watches, the outcome of her case could shape the future of athletics far beyond the 800-meter track.
