Asser International Sports Law Blog

During the 2023/2024 academic year, the Asser International Sports Law Centre will dedicate special attention to the intersection between transnational sports law and governance and gender. This online discussion is the first of a series of (online and offline) events which will explore the way in which international SGBs and the CAS define the gender divide in international sports, police gender-based abuses, and secure gender-specific rights to athletes.

Caster Semenya, a South-African runner and Olympic champion, was dominating her favorite distance, the 800m, for a number of years, when in 2018 the World Athletics (then known as IAAF) adopted a new set of regulations (colloquially known as the DSD Regulations), which imposed new conditions to the eligibility of athletes for certain female competitions, such as the 800m. Semenya, who has a condition known as differences in sex development (DSD), was forced to decide between subjecting to a specific medical treatment aimed at diminishing the level of testosterone in her body or stopping competing on her preferred distance. As she refused to undergo any medical treatment to regain eligibility, she decided to challenge the legality of World Athletics DSD Regulations before the CAS in Lausanne. While the CAS acknowledged that the Regulations were discriminatory and were disregarding the legal sex of Semenya in the name of a so-called sporting sex, the arbitrators also considered that this discrimination was justified and proportionate. Semenya’s challenge against the award was rejected by the Swiss Federal Tribunal (SFT) in August 2020. As a last resort, she decided to lodge an application with ECtHR against Switzerland.

On 11 July 2023, the ECtHR released its judgment in the much-awaited Caster Semenya v. Switzerland case. In short, the Strasbourg Court sided with Semenya and concluded that Switzerland failed to comply with its positive obligations stemming from the European Convention on Human Rights. The ruling is an important milestone in the interaction between the CAS and (European) human rights law. It will likely affect the place of human rights (and in particular the ECHR) at the CAS, the intensity of the supervision exercised by the SFT, as well as the justification of the regulatory decisions of the SGBs. We look forward to discussing these with our two speakers, who have followed closely the case and already blogged (here and here) about the judgment:

• Dr. Lena Holzer is Assistant Professor in Gender, Race and the Law at the University of Cambridge and the author of ‘What Does it Mean to be a Woman in Sports? An Analysis of the Jurisprudence of the Court of Arbitration for Sport’.
• Dr. Michele Krech is Harry A. Bigelow Teaching Fellow, Lecturer in Law at the University of Chicago she is the author of ‘The Misplaced Burdens of ‘Gender Equality’ in Caster Semenya v IAAF: The Court of Arbitration for Sport Attempts Human Rights Adjudication’ and ‘To Be a Woman in the World of Sport: Global Regulation of the Gender Binary in Elite Athletics’.

The online discussion will be introduced and moderated by Dr. Antoine Duval and Dr. Daniela Heerdt, and will include short presentations by the speakers and a Q&A with the audience.

1.     Introduction

The famous South African athlete Caster Semenya is in the last lap of her long legal battle for her right to run without changing the natural testosterone in her body. After losing her cases before the Court of Arbitration for Sport (CAS) and the Swiss Federal Tribunal, she filed an application before the European Court of Human Rights (Court). In the meantime, the Court has released a summary of her complaint and a series of questions addressed to the parties of the case.

As is well known, she is challenging the World Athletics’ Eligibility Regulations for the Female Classification (Regulations) defining the conditions under which female and intersex athletes with certain types of differences of sex development (DSDs) can compete in international athletics events. Despite the Regulations emanating from World Athletics, the last round of her legal battle is against a new opponent: Switzerland.

The purpose of this article is to revisit the Semenya case from a European Convention on Human Rights (ECHR) perspective while considering certain excellent points made by previous contributors (see here, here and here) to this blog. Therefore, the blog will follow the basic structure of an ECHR case. The following issues raised by Semenya shall be analysed: the applicability of the ECHR, Semenya’s right to private life (Article 8 ECHR) and to non discrimination (Article 14 ECHR), as well as the proportionality of the Regulations.

Sport is the field par excellence in which discrimination
against intersex people has been made most visible.

Commissioner for Human Rights, Council of Europe
Issue Paper: Human rights and intersex people (2015)

Olympic and world champion athlete Caster Semenya is asking the European Court of Human Rights (ECtHR) to make sure all women athletes are “allowed to run free, for once and for all”. Semenya brings her application against Switzerland, which has allowed a private sport association and a private sport court to decide – with only the most minimal appellate review by a national judicial authority – what it takes for women, legally and socially identified as such all their lives, to count as women in the context of athletics. I consider how Semenya’s application might bring human rights, sex, and sport into conversation in ways not yet seen in a judicial forum. More...

For the last three days, I have been struggling with what to write regarding the Swiss Federal Tribunal’s (SFT) Decision to dismiss a challenge from Caster Semenya and Athletics South Africa (ASA) against the Court of Arbitration for Sport’s (CAS) Decision to dismiss a challenge to the Eligibility Regulations for the Female Classification (Athletes with Differences of Sex Development), otherwise known as the DSD Regulations. From reading World Athletics’ statement welcoming the ruling, one could be forgiven for thinking that it had won a major trial. Sports journalists, accustomed to covering events now curtailed by Covid-19, focus on the fact that Semenya has ‘lost’ her case against the DSD Regulations. Neither assertion is strictly accurate.

The SFT’s powers to review the CAS’s ruling are severely limited. It can only consider whether the CAS Decision violates ‘widely recognised principles of public order’ on Swiss public policy grounds. The SFT has only reversed a decision based on a a violation of Swiss public policy once in 30 years.

The SFT didn’t reconsider the evidence put forward to the CAS. ‘For there to be incompatibility with public policy, it is not enough that the evidence has been poorly assessed, that a finding of fact is manifestly false or that a rule of law has been clearly violated’, its Decision reads. ‘The only question to be resolved is in fact whether or not the verdict of the CAS renders the referred award incompatible with substantive public policy’. 

There were questions about whether the appeal from Semenya and ASA qualified to be reviewed by the SFT in the first place. World Athletics is a private organisation headquartered in Monaco, and the SFT was troubled as to whether such a complaint brought by a South African athlete against an overseas private organisation is capable of violating Swiss public policy.

‘It is doubtful whether the prohibition of discriminatory measures falls within the scope of the restrictive concept of public order when the discrimination is committed by a private person and occurs in relations between individuals’, the Decision quotes from its pervious 29 July 2019 Decision, which refused the ASA’s request to provisionally suspend the application of the DSD Regulations. ‘In any event, there is no need to examine this question further here since […] the award under appeal does not in any way establish discrimination which would be contrary to public order’. 

The SFT ruled that the CAS was correct to uphold conditions of participation for 46 XY DSD athletes in order to guarantee fair competition for certain disciplines in female athletics. In doing so, the SFT was ruling on whether the decision taken by the CAS violates public policy, based only on the complaints brought forward by Semenya and ASA. 

Semenya and the ASA had challenged the CAS Decision based around the idea that the DSD Regulations are discriminatory. The CAS held that they are discriminatory, but agreed with the IAAF (as World Athletics was then named) that such discrimination was necessary to protect its female category. The SFT ruled that even if the discriminatory rules of a private organisation such as the IAAF were considered able to pose a threat to public order, Semenya and the ASA had failed to demonstrate that the CAS Decision was so egregious that it posed such a threat.

‘Caster Semenya essentially alleges a violation of the prohibition of discrimination’, reads the Swiss Federal Supreme Court statement. ‘The CAS has issued a binding decision based on the unanimous opinion of the experts who were consulted that testosterone is the main factor for the different performance levels of the sexes in athletics; according to the CAS, women with the “46 XY DSD” gene variant have a testosterone level comparable to men, which gives them an insurmountable competitive advantage and enables them to beat female athletes without the “46 XY DSD” variant. Based on these findings, the CAS decision cannot be challenged. Fairness in sport is a legitimate concern and forms a central principle of sporting competition. It is one of the pillars on which competition is based. The European Court of Human Rights also attaches particular importance to the aspect of fair competition. In addition to this significant public interest, the CAS rightly considered the other relevant interests, namely the private interests of the female athletes running in the “women” category.’

Such strong support for the principle behind its DSD Regulations was rightly welcomed by World Athletics. Its statement asserted that the SFT ‘acknowledged that innate characteristics can distort the fairness of competitions’. I would argue that the SFT ruling didn’t do this, but rather found that a CAS Decision asserting this didn’t violate Swiss public policy. Semantics, perhaps.

Likewise, when World Athletics quotes the SFT Decision as confirming that ‘It is above all up to the sports federations to determine to what extent a particular physical advantage is likely to distort competition and, if necessary, to introduce legally admissible eligibility rules to remedy this state of affairs’, it is paraphrasing two texts quoted in the SFT Decision. The first is ‘La qualification juridique des rules autonomes des organizations sportive’ by Jérôme Jaquier, 2004. ‘Inborn characteristics specific to athletes in a particular group can also distort the fairness of competition’, the SFT Decision quotes from Jaquier. ‘When they enact regulations, the objective of sports federations is to ensure fair and equitable competition’.

The context of the second quote, from ‘Sportrecht – Berücksichtigung der Interessen des Sports in der Rechtsordnung’ by Martin Kaiser, 2011, is even more interesting. It is preceded with a statement from the Swiss Federal Supreme Court, which reads: ‘It is not for the Federal Court to make, abstractly, comparisons between the disciplines to assess whether a particular athlete has an advantage that makes sporting competition meaningless’. 

‘It is above all for the sporting federations to determine to what extent a particular physical advantage is liable to distort competition’, the SFT Decision quotes from Kaiser. ‘And, if so, to establish legally admissible eligibility rules to remedy this state of affairs’. 

Again, such details might be considered as semantics. But – I would argue – important semantics. Reading the media maelstrom that has resulted from the SFT Decision, one could be forgiven for assuming that Semenya has lost her case, and has no chance of ever defending her 800m title. However, a statement issued by her lawyers reveals that she intends to challenge the ruling in European and domestic courts.

“I am very disappointed by this ruling, but refuse to let World Athletics drug me or stop me from being who I am”, the statement continues. “Excluding female athletes or endangering our health solely because of our natural abilities puts World Athletics on the wrong side of history. I will continue to fight for the human rights of female athletes, both on the track and off the track, until we can all run free the way we were born. I know what is right and will do all I can to protect basic human rights, for young girls everywhere.” More...

The issue of international human rights was a central contention in Caster Semenya case ever since the start of her legal battle against the regulations of the IAAF. However, the human rights arguments were poorly considered in the two proceedings related to this case. To put it in perspective, it is like having a key player nailed to the bench throughout the whole game; no coach ever tried to give it a chance while it had the potential to be the game changer for all parties.

In 2019, the Human Rights Council, the inter-governmental human rights body of the UN, expressed concern over issues of discrimination in sports in particular regarding IAAF female classification regulations. In June 2020, the United Nations High Commissioner for Human Rights submitted a report to the United Nations Human Rights Council on the “Intersection of Race and Gender Discrimination in Sport”. The report draws a detailed picture of how human rights in the Semenya case have been violated and also elaborates on the inherent problem of addressing human rights issues in alternative dispute resolution mechanisms favored by the sport governing bodies. However, despite an in-depth discussion of Caster Semenya’s case at both the CAS and then the SFT, the question of human rights, a key concern and a fundamental pillar of the case, hasn’t been adequately answered yet!

Even though the decision rendered by the SFT in the Semenya Case was foreseeable, the Tribunal did put forward some concerning reasoning in terms of public policy (“ordre public”) and human rights. In case Semenya decides to challenge the Swiss state before the ECtHR, one can expect the case to shake some grounds at the ECtHR, which would be faced with the question of the application to sport not of fair trial guarantees (as in Mutu & Pechstein) but of substantial human rights provisions such as the prohibition of discrimination on the basis of sex (Article 14 ECHR) and the right to private life (Article 8 ECHR).

Under Swiss law, the reasons that may lead to the annulment of an arbitral award are enumerated in art. 190 of the Swiss Private International Law Act (PILA). Semenya’s strongest case relied on art. 190(2)(e): the award’s incompatibility with public policy. Naturally, this point concentrated most of the SFT’s attention. In order to analyze the compatibility of the CAS award with Swiss public policy, the SFT focused on three main potential breaches of human rights: prohibition of discrimination, personality rights, and human dignity. In doing so, it put forward certain observations that differ with European human rights standards and the ECtHR’s jurisprudence. The purpose of this short article is to analyze those discrepancies and, consequently, Semenya’s prospects of success before the Strasbourg Tribunal.More...

As the title indicates, this short note only deals with selected procedural issues and questions arising out of the very lengthy Semenya Judgment. In a nutshell, the SFT dismissed Semenya’s appeal to set aside the CAS Award, which had denied the request of Caster Semenya (Semenya, the Athlete) to declare unlawful the Differences of Sex Development (DSD) Regulations of World Athletics (formerly IAAF).[1]

At the outset, it has to be reminded that the CAS Award dealt with the merits of the Semenya case in a final and binding way by rendering an arbitral award according to Article R59 of the CAS Code (and Article 190 of the Swiss Private International Law Act – PILA). Therefore, the SFT did not act as an appellate court but rather as a cassatory court, entitled to review only whether the exhaustively enumerated grounds for annulment set out in Article 190 (2) PILA were met (and provided that they were properly invoked and substantiated in the motion to set aside said award).More...

The decision this week by the Swiss Federal Tribunal not to revisit the arbitral decision of the Court of Arbitration for Sport (CAS) in the case of Caster Semenya was not unexpected, but it does help to expose a major design flaw in international sports governance. Specifically, the institutions that collectively comprise, create and enforce “sports law” appear incapable of addressing flawed science and violations of basic principles of medical ethics.

While different people will have different, and legitimate, views on how male-female competition classifications might be regulated, the issues highlighted involving science and ethics are not subjective, and are empirically undeniable. In normal systems of jurisprudence, procedures are in place to right such wrongs, but in sports governance processes in place prevent such course corrections. And that is a problem.

The empirical flaws in the science underpinning the IAAF (now World Athletics) Semenya regulations are by now well understood, and have been accepted by WA in print and before CAS (I was an expert witness for Semenya, and was present when IAAF accepted responsibility for the flawed research). You can read all the details here and in the CAS Semenya decision. I won’t rehash the flawed science here, but the errors are fatal to the research and obvious to see.

One key part of the comprehensive institutional failures here is that the journal which originally published the flawed IAAF research (the British Journal of Sports Medicine, BJSM) has, inexplicably, acted to protect that work from scrutiny, correction and retraction. Normally in the scientific community, when errors of this magnitude are found, the research is retracted. In this case, the BJSM refused to retract the paper, to require its authors to share their data or to publish a critique of the IAAF analysis. Instead, upon learning of the major errors, the BJSM published a rushed, non-peer reviewed letter by IAAF seeking to cover-up the errors. All of this is non-standard, and a scandal in its own right.

The violation of basic principles of medical ethics required by the implementation of the WA Semenya regulations is also not contested. Both WA and the IOC have claimed to uphold the World Medical Association’s Helsinki Declaration on medical and research ethics. Yet, the WMA has openly criticized the WA regulations as unethical and asked doctors not to implement them. In response, WA has stated that it will help athletes who wish to follow the regulations to identify doctors willing to ignore medical ethics guidelines.

Flawed science and ethical violations are obviously issues that go far beyond the case of Caster Semenya, and far beyond sport. In any normal system of jurisprudence such issues would prove readily fatal to regulatory action, either in the first instance of proposed implementation or via review and reconsideration.

Sport governance lacks such processes. At CAS, the panel claimed that matters of scientific integrity and medical ethics were outside their remit. The SFT is allowed to reconsider a CAS decision only on narrow procedural grounds, and thus also cannot consider matters of scientific integrity or medical ethics. So far then, the flaws in the WA regulations – sitting in plain sight and obvious to anyone who looks, have not been correctable.

This leaves the world of sport governance in a compromised position. Some may look past the scientific and ethical issues here, perhaps judging that barring Semenya from sport is far more important that correcting such wrongs. 

Regardless of one’s views on sex and gender classification in sport, the WA regulations and the processes that produced and have challenged them reveal that sports governance has not yet entered the 21^st century. Science and ethics matter, and they should matter in sport jurisprudence as well.  It is time to correct this basic design flaw in international sport governance.

1.     Caster Semenya appealed to the Swiss Federal Court (SFT) arguing that World Athletics’ regulations violated human rights principles relating to gender discrimination and human dignity. The Swiss Federal Tribunal (as at CAS) held that World Athletics’ regulations may prima facie breach such human rights principles but were “necessary, reasonable and proportionate” to maintain fairness in women's athletics;

2.     Although in part addressed at the SFT, expect further legal argument on this in the domestic courts of South Africa or at the ECtHR, and in the following ways:

• Necessity - is the athletic advantage that Caster Semenya has of such a scientifically-measurable extent that it is necessary for World Athletics to intervene in such an invasive manner? In a broader ethical sense, is the incidence of what the World Athletics’ regulations call “difference of sex development” of such prevalence in the general population, and specifically in middle-distance athletics, that, by way of the principle of “sporting beneficence”, intervention is justified. Or, in contrast, is the incidence of DSD not at a level which justifies a departure from the ethical principle of primum non nocere – first, do no harm?

• Reasonableness - if World Athletics’ regulations are necessary, is the manner of implementation reasonable and in line with the principle of human and bodily integrity? In answering such a question, the focus must be on the fact that in order to continue to compete in her favourite events (such as the 800 metres) Caster Semenya will have to lower her testosterone level through medication;

• Proportionate - if World Athletics’ regulations are necessary and reasonable is the manner of implementation proportionate? In answering such a question, the focus must be on whether the regulations disproportionately discriminate against a certain, limited group of athletes in a certain, limited number of events and in a certain, limited manner.More...

On 25 August 2020, the Swiss Supreme Court (Swiss Federal Tribunal, SFT) rendered one of its most eagerly awaited decisions of 2020, in the matter of Caster Semenya versus World Athletics (formerly and as referenced in the decision: IAAF) following an award of the Court of Arbitration for Sport (CAS). In short, the issue at stake before the CAS was the validity of the World Athletics eligibility rules for Athletes with Differences of Sex Development (DSD Regulation). After the CAS upheld their validity in an award of 30 April 2019, Caster Semenya and the South African Athletics Federation (jointly: the appellants) filed an application to set aside the award before the Swiss Supreme Court.[1] The SFT decision, which rejects the application, was made public along with a press release on 8 September 2020.

There is no doubt that we can expect contrasted reactions to the decision. Whatever one’s opinion, however, the official press release in English does not do justice to the 28-page long decision in French and the judges’ reasoning. The goal of this short article is therefore primarily to highlight some key extracts of the SFT decision and some features of the case that will be relevant in its further assessment by scholars and the media.[2]

It is apparent from the decision that the SFT was very aware that its decision was going to be scrutinised by an international audience, part of whom may not be familiar with the mechanics of the legal regime applicable to setting aside an international arbitration award in Switzerland.

Thus, the decision includes long introductory statements regarding the status of the Court of Arbitration for Sport, and the role of the Swiss Federal Tribunal in reviewing award issued by panels in international arbitration proceedings. The SFT also referred extensively throughout its decision to jurisprudence of the European Court of Human Rights (ECtHR), rendered in cases related to international sport and the CAS. More...
