Call for Papers - 20 Years of the World Anti-Doping Code in Action - ISLJ Conference 2025 - 6 & 7 November 2025


 


Call for papers

20 years of the World Anti-Doping Code in Action

International Sports Law Journal Conference 2025

Asser Institute, The Hague

6 and 7 November 2025

 

The Editors of the International Sports Law Journal (ISLJ), the Asser Institute and the Research Chair on Responsible Sport of the University of Sherbrooke invite you to submit abstracts for the ISLJ Conference on International Sports Law, which will take place on 6 and 7 November 2025 at the Asser Institute in The Hague. The ISLJ, published by Springer and T.M.C. Asser Press, is the leading academic publication in the field of international sports law and governance. The conference is a unique occasion to discuss the main legal issues affecting international sports with academics and practitioners from all around the world. 

 

The 2025 ISLJ Conference will focus on assessing the first 20 years (2004-2024) of operation of the World Anti-Doping Code (WADC) since its entry into force in 2004, while also discussing its future prospects, in light of the new version of the Code due to be adopted at the Busan Conference in December 2025 and the 10th Conference of the Parties to the International Convention against Doping in Sport, to be held in Paris from 20 to 22 October. The aim of the conference will be to take a comprehensive stock of the operation of the private-public transnational regulatory regime which emerged in the wake of the WADC.  This regime is structured around a complex network of national and global institutions engaged in anti-doping work (WADA, NADAs, IFs, accredited laboratories) and guided by an equally complex assemblage of norms located at the global (WADC and the WADA Standards), international (UNESCO Convention against Doping in Sport), regional (Council of Europe Anti-Doping Convention), and national (various national anti-doping legislations) level. This makes for a fascinating and convoluted transnational legal construct in need of being studied, analysed and criticised by scholars. 

 

Reviewing 20 years of implementation of the WADC warrants a special edition of the ISLJ Conference and of the journal, which invites scholars of all disciplines to reflect on the many questions and issues linked with it. We welcome proposals touching on the following subjects (and more): 

  • The governance of the world anti-doping regime
    • The public-private nature of this governance
    • The transparency of this governance
    • The legitimacy of this governance
    • The participatory nature of this governance
    • The role of scientific experts in this governance
  •  The normative content of the WADC and the international standards
    • The strict liability principle 
    • The privacy rights of athletes under the WADC
    • The sanctioning policy under the WADC
    • The role of the international standards in implementing the WADC
    • The compatibility of the WADC with human rights
  • The glocal implementation of the WADC
    • The role of local institutions (NADOs/Labs/NOCs) in the implementation of the WADC
    • The tension between global (WADA) and local (NADOs/Labs/NOCs) in the implementation of the WADC
    • The role of the IFs in the implementation of the WADC
    • The role of the ITA in the implementation of the WADC
    • The role of judicial bodies (national courts, disciplinary committees of IFs, CAS) and their jurisprudence in the implementation of the WADC 
  • The effectiveness of the world anti-doping regime
    • The evaluation and evolution of the effectiveness of the world anti-doping regime in preventing doping
    • The role of the media in unveiling the ineffectiveness of the world anti-doping regime
    • The role of states in hindering the effectiveness of the world anti-doping regime
    • The world anti-doping regime as a regime with a variable geometry of effectiveness
  •  The future of the world anti-doping regime: Revolution, reform or more of the same?
    • Do we need a world anti-doping regime? 
    • If we do, should it be reformed? How? 


Abstracts of 300 words and CVs should be sent no later than 1 June 2025 to a.duval@asser.nl. Selected speakers will be informed by 30 June 2025. The selected participants will be expected to submit a draft paper by 15 October 2025. Papers accepted and presented at the conference are eligible for publication in a special issue of the ISLJ subject to peer-review. The Asser Institute will provide a limited amount of travel and accommodation grants (max. 350€) to early career researchers (doctoral and post-doctoral) in need of financial support. If you wish to be considered for a grant, please indicate it in your submission.  


Zoom-In Webinar - The Aftermath of the Diarra Judgement: Towards a New FIFA Transfer System? - 20 November - 16:00-18:00 CET

On 4 October, the Court of Justice of the European Union shook the world of football with its Diarra ruling. The decision questions the compatibility of a key provision of the FIFA Regulations on the Status and Transfer of Players (RSTP) with European Union internal market law. The RSTP, and in particular its article 17, are the bedrock of football’s transfer ‘market’ and regulate the conditions for the transnational movement of players between clubs. In 2023, based on FIFA’s numbers, 21 801 players were transferred internationally (of which 3279 with a fee) for transfer fees amounting to USD 9.63 bn. In short, this is a market that affects a considerable number of players and is linked with the movement of large sums of money between clubs and other actors (such as intermediaries).

Join us on 20 November from 16:00 to 18:00 CET to take stock of the ruling's impact and discuss the steps ahead in a free Zoom-In webinar in which there will be time for a Q&A session with the speakers. The ruling has already been much commented on (see hereherehere, and here), and this zoom-in webinar will be an opportunity for participants to engage with two experts on the economic and legal intricacies of the regulation of labour relations in football. We will mostly focus on the aftermath of the judgment and the question, 'what comes next?'

Drivers and effects of reform in transnational sports governance 

Transnational sports governance seems to be in a permanently unstable state of crisis and reform. At regular interval, international sports governing bodies face scandals triggered by corruption investigations or human rights violations, as well as adverse judidicial decisions. These are often followed by waves of institutional reforms, such as the creation of new bodies (E.g. the Athletics Integrity Unit), the adoption of new codes and regulation (such as Codes of Ethics) or human rights commitments (e.g. FIFA and the IOC’s Human Rights Policy/Strategy). This dynamic of crisis and reform will be at the heart of this year’s ISLJ conference, as a number of panels will critically investigate the triggers, transformative effects and limited impacts of reforms in transnational sports governance.  

Football in the midst of international law and relations 
As the war in Gaza and Russia’s invasion of Ukraine continue to rage, it has become even clearer that the football world can hardly be entirely abstracted from international relations. Yet, FIFA and UEFA continue to insist on their neutrality and to deny that their governance is (or should be) affected by the world’s political affairs. During the conference, we will engage with case studies in which football is entangled with international politics and law. In particular, the speakers will delve into the role of FIFA and UEFA in such situations and on the legal standards and processes that should be applied throughout their decision-making.  

Olympic challenges of today and tomorrow 
While the Paris 2024 Olympics have come to a close, the legal questions they have raised are far from exhausted. Instead, the Olympics have highlighted new issues (such as the question of the legality of the hijab ban imposed by the French Federation on its athletes) or old ones (such as the question whether Olympians should be remunerated by the IOC or the international federations), which will be discussed by our speakers. Finally, with the help of our keynote speaker, Prof. Jules Boykoff, a longstanding critique of the current Olympic regime, we will explore the IOC’s capacity to adapt to challenges while resisting radical change to the current model of olympism.

Luxembourg calls…is the answer from Nyon the way forward? Assessing UEFA’s response to the ECJ’s ISU judgment - By Saverio Spera

 

Editor's note: Saverio P. Spera is an Italian qualified attorney-at-law. He has practiced civil and employment law in Italy and briefly worked at the Asser International Sports Law Centre before joining FIFA in 2017. Until May 2024, he has worked within the FIFA legal division - Litigation Department, and lectured in several FIFA sports law programmes. In the spring of 2024 he has co-founded SP.IN Law, a Zurich based international sports law firm.

 

 

On 21 December 2023 a judicial hat-trick stormed the scene of EU sports law. That day, the European Court of Justice (the “ECJ”) issued three decisions: (i) European Superleague Company, SL v FIFA and UEFA (Case C-333/21); (ii) UL and SA Royal Antwerp Football Club v Union royale belge des sociétés de football association ASBL (Case C-680/21)and (iii) International Skating Union (ISU) v. European Commission – Case C-124/21.

These judgments were much scrutinised (see herehere and here) in the past 6 months. For the reader’s relief, this paper will not venture into adding another opinion on whether this was a fatal blow to the foundation of EU sports law or if, after all, the substantive change is minimal (as persuasively argued here). It will analyse, instead, UEFA’s recent amendments of its Statutes and Authorisation Rules governing International Club Competitions (the “Authorisation Rules”) and whether these amendments, clearly responding to the concerns raised in the ISU judgment with respect to the sports arbitration system,[1] might pave the way for other Sports Governing Bodies (SGBs) to follow suit and what the implications for CAS arbitration might be.

Women’s Football and the Fundamental Right to Occupational Health and Safety: FIFA’s Responsibility to Regulate Female Specific Health Issues - By Ella Limbach

Editor's noteElla Limbach is currently completing her master’s degree in International Sport Development and Politics at the German Sport University Cologne. Her interests include human rights of athletes, labour rights in sport, the intersection of gender, human rights and sport and the working conditions in women’s football. Previously, she graduated from Utrecht University with a LL.M in Public International Law with a specialization in International Human Rights Law. This blog was written during Ella's internship at the Asser Institute where she conducted research for the H.E.R.O. project. The topic of this blog is also the subject of her master's thesis.

Women’s football has experienced exponential growth over the past decade, though the professionalization of the women’s game continues to face barriers that can be tied to the historical exclusion of women from football and insufficient investment on many levels. While attendance records have been broken and media coverage has increased, the rise in attention also highlighted the need for special accommodations for female footballers regarding health and safety at the workplace. Female footballers face gender specific circumstances which can have an impact on their health such as menstruation, anterior cruciate ligament (ACL) injuries and the impact of maternity. As the recent ILO Brief on ‘Professional athletes and the fundamental principles and rights at work' states “gender issues related to [occupational health and safety] risks are often neglected (p. 23).” While it could be argued that from a human rights point of view article 13(c) of the Convention on the Elimination of Discrimination of Women stipulates “the right to participate in […] sports [on an equal basis to men],” reality shows that so far practices of men’s football were simply applied to women’s football without taking into consideration the physiological differences between male and female players and the implications that can have for female players’ health. The ILO Declaration on Fundamental Principles and Rights at Work(ILO Declaration, amended in 2022) includes “a safe and healthy working environment” as one of the fundamental rights at work (Art. 2e). This begs the question whether the scope of the right to occupational health and safety at the workplace includes the consideration of female specific health issues in women’s football. More...

12th round of Caster Semenya’s legal fight: too close to call? - By Jeremy Abel

Editor's note: Jeremy Abel is a recent graduate of the LL.M in International Business Law and Sports of the University of Lausanne.

 

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.

2.     Applicability of the ECHR

An interesting question is how the Court will apply the ECHR to the case at hand. It has two options at its disposal. It can either use the doctrine of positive or negative obligations to resolve the case. The most logical solution would be to favour the positive obligations route. This doctrine allows the Court to hold states accountable in situations involving private parties. It obliges states to intervene in these situations and not to simply sit back and remain passive. In essence, the present case opposes two private parties: Caster Semenya on the one side and World Athletics on the other. The only connection of the case to Switzerland is a judgment by its Federal Tribunal reviewing the award rendered by the CAS. Indeed, unlike most international federations, World Athletics is registered in Monaco and not in Switzerland.

The Court’s case law also appears to favour this option. In Mutu and Pechstein, the Court indirectly stated that Switzerland’s positive obligations were at play (paras 65-67). The problem with this approach is that it makes it difficult to test a set of private regulations directly against the Convention. In its Mutu and Pechstein decision, the Court sidestepped this problem by somewhat ignoring Switzerland’s positive obligations. It simply applied the requirements of Article 6 ECHR directly to the CAS proceedings without worrying about the role of Switzerland and its Federal Tribunal.[1] Mutu and Pechstein suggests that the Court is willing to use the positive obligations doctrine and tweak it where it feels it is necessary to uphold athletes’ Convention rights. It is argued here that the Court’s approach in Semenya will be similar since the case raises several fundamental rights questions which have not been dealt with extensively by previous courts.

3.     Substantive issues

a.      Semenya’s right to private life (Article 8 ECHR)

Another crucial question is whether the Court will be willing to rely on its Article 8 ECHR case law relating to transgender persons. A.P., Garçon and Nicot is of particular importance in this context. This case was about a French law making the recognition of transgender persons’ preferred gender conditional on a sterilisation surgery or treatment. The Court stated that this law presented transgender persons not willing to undergo sterilisation with an “impossible dilemma” (para 132). They had to choose between their physical integrity or the legal recognition of their gender identity. The Court deemed this burden to be unnecessary to guarantee the principle of the inalienability of civil status and the need for consistency and reliability of civil-status records and thus in violation of Article 8 ECHR.

The Regulations create a similar dilemma. Despite having been identified by the South African State and identifying herself as a female, Semenya cannot compete in the female category unless she compromises her right to physical integrity by undergoing testosterone lowering treatment. In addition, noncompliance with the Regulations means that she cannot run the middle-distance events she excels at. It is therefore likely that she must give up her international sports career.[2]

It can be argued that both cases are comparable. While it is true that, unlike the French law, the Regulations aim her sports status and not her legal sex, both rules are not so different when one considers the specificity of her profession. As a famous athlete whose life revolves around sport, a mismatch between her legal sex and “sports” sex has major consequences on her life as a professional athlete and beyond. In these special circumstances, it is difficult to strictly differentiate the legal sex from the “sports” sex. Indeed, she finds herself in the very peculiar situation of suddenly having to explain why, after a lifetime of being female for the purposes of both sex categories, she is still female enough for one but not the other. Another distinction between the Regulations and the French law is that the latter contained a sterilization requirement absent in the former. This distinction can be relativised in two ways. Firstly, both set of rules require the same type of medical treatment: surgery or hormone treatment. Secondly, although the Regulations do not require a permanent physical change, the recommended surgical and hormonal treatment may lead to irreversible changes and ultimately sterility.[3]

b.      Semenya’s right to non discrimination (Article 14 ECHR)

Regarding the potential discriminatory nature of the Regulations in the sense of Article 14 ECHR, Semenya will most likely question why the Regulations only institute a testosterone limit for female athletes. This assertion runs up against the legal hurdle of finding an appropriate comparator. For there to be a discrimination, it must in principle be possible to compare Semenya with a class of persons who are treated more favourably. This task is not made easier by the fact that no intersex case has ever been decided by the Court.[4]

In theory, three comparisons are imaginable[5]: a comparison with male, female, or intersex athletes. The viability of each comparator depends on which definition of sex is used.[6] Sex can be understood from a civil status, gender identity or biological standpoint. It is unclear whether the Court will be convinced by World Athletics’ preference for the biological sex definition. World Athletics used this definition to argue that Semenya is “biologically male” for the purpose of athletics and must therefore be compared to male and not female athletes.[7] If the condition of participation is being “biologically female”, there is no discrimination because Semenya is being treated like all the other athletes who do not fulfil this condition.[8] However, the situation completely changes if the biological sex definition is dropped in favour of the others.

4.     Proportionality of the Regulations

Finally, the Court may have to engage in a delicate balancing act between the different interests at stake. On the one hand, there are the interests of World Athletics. As an international federation, it considers it is in the best position to develop the most appropriate rules for dividing females and males for the purpose of athletics. On the other hand, there are the opposing interests of Semenya and her fellow competitors. It is a classic case of competing rights which happen also to be fundamental goals of sport: inclusion vs fairness.[9] Including intersex athletes in the female category might be unfair towards the other female athletes. Contrary to other physical or genetical traits, high levels of testosterone are viewed by some to give intersex athletes an insurmountable advantage over their female competition. By adopting and defending the Regulations, it is clear that World Athletics shares this view and is sensitive to the fairness argument.

One way of avoiding this balancing of interests exercise is to decide that the Regulations are not fit for purpose. Without getting into scientific arguments, it appears safe to affirm that while most experts agree that testosterone has a positive effect on performance, there is still a lack of consensus on the degree of that effect.[10] Both the CAS and the Swiss Federal Tribunal overcame this uncertainty by giving a lot of weight to the statistical overrepresentation of women with DSDs in elite athletics.[11] A striking example of this overrepresentation is the women’s 800 m final at the 2016 Olympics where Semenya and two other athletes with DSDs occupied all three podium places thanks to the suspension of a previous version of the Regulations.

However, an alternative view is plausible. The capability of the Regulations to achieve their goal of ensuring fairness can be called into question on three fronts.

Firstly, there is a twofold problem relating to the quality of the evidence and the conclusions drawn from it. The quality of the evidence is low because in addition to there only existing few studies on the relationship between testosterone and performance, those that do exist rely on flawed data such as double counting athletes and times.[12] Irrespective of the concerns regarding the quality of the evidence used, the conclusions drawn from it are inconsistent because World Athletics’ choice to establish a testosterone limit for some, but not other athletic events is illogical.[13] According to the evidence, female athletes with high levels of testosterone have a competitive advantage in the following athletic disciplines: 400 m (2,73%), 400 m hurdles (2,78%), 800 m (1,78%), hammer throw (4,53%) and pole vault (2,94%).[14] No performance advantage was shown to exist in other athletic disciplines.[15] The inclusion of the 1500 m and one mile events into the Regulations but not the hammer throw and pole vault runs counter to the evidence and the goal of ensuring a level playing field.

Secondly, there appears to be no satisfying answer as to why there is no equivalent testosterone limit for male athletes despite their testosterone levels differing much more significantly[16].

Thirdly, the choice of using testosterone as the determining factor can be called into question. Given the wide range of physical attributes that are helpful in sport, it is not clear what makes testosterone so different from other physical attributes. Would a mix of physical attributes and parameters like the one used in Paralympics not be fairer and more inclusive?[17]

5.     Conclusion

The Semenya case has the potential to appreciably change international federations’ and Switzerland’s relationship with the ECHR. It is shown above that if the Court wants to apply the ECHR directly to the Regulations, it must bend the doctrine of positive obligations. Until now, the Court has not explained its unconventional use of the doctrine. Two explanations are at the Court’s disposal.[18] They are both premised on the idea that Semenya is in a position of dependence towards World Athletics.

Firstly, it is possible to extend the reasoning behind Mutu and Pechstein according to which the CAS (a private Court) must, in situations involving forced arbitration, offer the same fair trial guarantees as a state court, to all types of sports regulations.[19] Indeed, if one accepts that sports arbitration clauses are compulsory, it becomes very difficult to argue that sports regulations in general are not compulsory since the former are contained in the latter.[20]

Secondly, the Court can treat international federations analogous to state-like entities.[21] The relationship between Semenya and World Athletics is akin to that between regular citizens and a state due to the size, power, and monopolistic position it holds in the sport of athletics.[22] The Semenya case exemplifies this power imbalance well. World Athletics’ monopoly means that it can impose the Regulations upon Semenya. She cannot object to this effectively since giving up her international athletics career is not an option as she would put her livelihood at risk.[23]

In the present case, the first explanation is more fitting because World Athletics’ seat is in Monaco and not in Switzerland. If, as argued here, the Court bends the positive obligations doctrine to properly engage with the arguments raised by Semenya, this would give it the opportunity to explain its unusual approach. But even if the Court does not take this opportunity, its unconventional use of the doctrine of positive obligations would still send a message to international federations and Switzerland that they must take ECHR considerations seriously in spite of the private nature of international sports disputes.

Beyond the question of the applicability of the Convention, the Semenya case has the potential to have far-reaching consequences for the world of sports. This is because of the wide-ranging reach of the Court’s decisions and the fact that World Athletics’ policy on intersex athletes is based on a recommendation made by the International Olympic Committee (IOC). As the supreme governing body of global sports, the IOC’s policy on this matter influences sports regulations at all levels throughout the world.

Finally, the case is infused with highly relevant but difficult scientific, sports and societal issues. The discussions around the definition of sex are particularly sensitive in today’s society. The complexity and sensitive nature of the case as well as the clash between two fundamental goals of sport are all ingredients for an extremely contentious fight which will ultimately come down to the judges’ scorecards. Whilst a split decision is likely, controversy is certain.
