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.

1.     Introduction

The surge of e-sports has stimulated a lively discussion on the essential characteristics of sport and whether e-sports, in general, can be considered a sport. However, one should not overlook the fact that e-sports encompass a broad range of video games that fundamentally differ from one another. Thus, as one commentator recently underlined, “the position of video games and the e-sport competitions based on them should be analysed on a case-by-case basis.”[1] In this spirit, this blog aims to provide a concise analysis of one of these e-sports, League of Legends (LoL), and one of its main competitions, the League of Legends European Championship (LEC), to assess whether it could be considered a sport in the sense of EU law. The LEC offers a fascinating opportunity to examine this issue especially since the previous European League of Legends Championship Series (EU LCS) was rebranded and restructured this year into the LEC.

2.     What is League of Legends and the LEC?

At the time of writing, LoL released nearly a decade ago by Riot Games (a game developer based in the USA) and rapidly became one of the most played video games in the world due in part to its free to play business model. This means that anyone can download and play LoL on their computer without ever having to pay anything. In-game microtransactions exist but do not provide any competitive advantage. The game itself involves two teams of five players who each control a ‘champion’, which are characters in the game that each possess unique abilities. A team only wins when it has destroyed the enemy base (‘nexus’). The game is not only a popular video game, but it is a popular e-sport. The most recent world championships finals attracted 99.6 million unique viewers. While these numbers are greatly due to its popularity in China and South Korea, there is also a sizeable European viewership of LoL. For example, the LEC regular season matches have reached a record-breaking 355,000 concurrent viewers in its 2019 spring competition.

The LEC is LoL’s highest level of European competition and is owned and organised by Riot Games who establishes and enforces the rules which apply to the teams participating in the LEC. Consequently, Riot Games is truly at the apex of professional LoL in Europe by setting both the in-game parameters (the rules of the game) and the regulations that govern its competitive play. As explained earlier, Riot Games restructured and rebranded its previous European competition, EU LCS, into the LEC. While previously the EU LCS was characterised by a pyramid structure with a promotion and relegation system familiar to the European sports world, the LEC introduced a franchise model to follow its sibling competition in North America, the League Championship Series (LCS). The LEC itself is a limited liability company registered in the Republic of Ireland as League of Legends European Championship Limited.[2] The LEC buy-in fee for teams already in the EU LCS was reportedly set at 8 million euros and 10.5 million euros for those outside the EU LCS. Additionally, big brands such as KIA, Shell, Foot Locker and Red Bull sponsor the LEC and are featured during the broadcast. Besides being produced and diffused weekly by the official Riot Games English broadcast team in a professional studio in Berlin on Twitch (an online video game livestreaming service) and YouTube, the LEC partners with other official broadcasters who provide coverage of the matches in other languages (French, Spanish, Polish, German, Italian). Nevertheless, before examining the LEC’s position under EU law, a review of the broader arguments on the fundamental traits of sport will contextualise the Court of Justice of the European Union’s (CJEU) interpretation of the concept of sport.

3.     Is LoL played in the LEC a sport competition?

The academic discourse on the definition of sport has provided a plethora of elements and conditions for an aspiring sport to meet in order to be considered a ‘real’ sport. Needless to say, this blog will not be able to address all of them. However, the characteristics identified by Suits and elaborated by Jenny et al. and Abanazir are a good starting point for this brief review.[3] Suits explains that sports are in essence games that require skill, where the skill requires physicality, that the game have a wide following, and that this following have a certain level of stability. Abanazir delved into the concept of stability in the e-sports context by explaining institutionalisation’s central role in achieving permanence.

On the first requirement, there is very little room to argue that professional LoL does not require a great amount of skill. Suits explains that games of skill provide ‘unnecessary obstacles’ (in relation to daily life) “to realize capacities not otherwise realizable” that do not rely on pure chance.[4] Playing LoL is not in any way a necessary part of human life, yet many players practicing LoL play to refine and improve their mechanical skill (the physical element of the game, e.g. muscle memory and reflexes). Chance sometimes plays a role in LoL, but it is rarely a decisive factor in determining the outcome of a competitive match. Generally, Riot Games has taken steps over the years to limit the elements of pure luck in its game.

The role of physical motor skills in e-sports has been explained in detail by van Hilvoorde and Pot, and this blog will not dive into the arguments on whether actions taken in a video game can be considered taking place in the ‘real’ world.[5] Assuming that it does, the skill required in LoL is intrinsically connected to its physicality. LoL is played on a computer with a mouse and a keyboard. High level play requires precise movement of the arm, wrist and/or hand to most effectively control one’s character with the mouse. Additionally, the clicks and inputs registered by one’s fingers on the mouse and keyboard must be timed precisely and with enough practice these movements become muscle memory. The classic example of a game that does not require this sort of physicality is chess because the manner in which one moves a chess piece from a to b does not affect the result of the game. On the other hand, LoL demands precise and timed movements of the player’s arms, wrists, and/or fingers to be played optimally. One can be a LoL strategic genius but without a sufficient level of mechanical skill, it is impossible to become a professional LoL player.

Next, a large following is probably the easiest criteria for LoL and the LEC to fulfil. Between the large viewership that watch the LoL events online and the thousands of spectators that come to watch the championships live, there is very little doubt that LoL and the LEC have a wide following at the moment. However, this point leads into the next element which arguably may be the hardest criteria for it to satisfy in the long term: stability.

Video games and consequently, e-sports, generally reach a point where they have achieved their max popularity and eventually begin to lose players and viewers. Often times, this is the result of newly released video games pushing older and ‘outdated’ games out of the spotlight. LoL has remained at the forefront of e-sports for nearly a decade and there is little suggestion that this will change in the near future. Part of this is Riot Games’ continued support of LoL by regularly updating the game. Updates are released nearly every other week and can range from graphical improvements, balancing the game to ensure the viability of new strategies, the introduction of new champions (currently 143 champions) and tweaks that improve the way the game runs on the computer. Abanazir describes that changes such as these “present a double-edged sword” because while they keep the game fresh for players, they can result in drastic changes to the best strategies (meta) to win the game.[6] Thus, professional teams and players must continually adapt their play to conform to the meta. Nevertheless, updates have never fundamentally changed the goal and overall ‘rules’ of the game. Professional LoL is always two teams of five players, each controlling one champion, aiming to destroy the enemy nexus.

From an outsider’s point of view, it may seem that the constant flux of the meta would truly damage any of LoL’s claim to stability. However, in this context, it is imperative to highlight the institutionalisation of the LEC. Institutionalisation describes the appearance of “standardisation of rules, the formalisation of learning of the games, the development of expertise and finally the emergence of coaches, trainers, officials and governing bodies.”[7] The very fact that the meta often changes have pushed professional teams to hire analysts that review the team’s play and are constantly searching for new and creative ways to play LoL. Additionally, all professional teams have at least one coach who not only define the team’s strategy before each game, but also ensure that players observe strict practice schedules. During LEC matches, referees (Riot Games employees) are always present in order to ensure that the LEC rules are observed, which greatly lends to the idea of a ‘standardisation’ of the rules.[8] In fact, Riot Games directly state that the creation of the LEC Rulebook is to help “unify and standardize the rules used in competitive play.”[9] From this outline, there are many indications that the LEC and LoL have many of the characteristics of a sport and currently have achieved a certain amount of stability and institutionalisation. The true test will be whether these structures continue to last as they have been developed and implemented over the past eight years.

4.     A Sport under EU Law?

Recently, the Court of Justice of the European Union (CJEU) ruled on whether the English Bridge Union could benefit from a sports exemption under the VAT Directive and in doing so examined the concept of sport under that Directive.[10] Furthermore, in this case, Advocate General (AG) Szpunar provided an enlightening opinion to the Court examining the concept of sport in the context of the VAT exemption.[11] Both provide a good opportunity to infer how the Court would perhaps go about determining whether the LEC is a sport competition under EU law. This being said, the sport exception in the current VAT Directive would not apply to the LEC since Article 132 (1) (m) applies only to services provided by non-profit organisations. Nonetheless, should League of Legends European Championship Limited eventually restructure into a non-profit, it would not be far-fetched to imagine a situation in which it would seek to have VAT reimbursed from authorities under a sports exception in the future. After all, Riot Games has repeatedly stated that it does not make a profit on its e-sport activities.[12]

The AG’s opinion began by explaining that the concept of sport in the exemption should be “interpreted in a narrow manner, while bearing in mind the purpose and objective of the exemption.”[13] From this it is clear that the analysis of the concept of sport differs depending on the applicable provision, which could mean that the LEC could be considered a sport competition under one provision and a purely economic activity in another context. The AG goes on to identifying elements which preclude an activity from being considered a sport and states that “where a physical element is not necessary, sport is defined by competition and the fact that equipment is provided by not just one supplier -  which excludes activities without a broad basis in civil society, such as commercial products in the market place, designed by firms for pure consumption (for instance video games).”[14] If this interpretation of the concept of sport had been endorsed by the CJEU, it would have constituted a tremendous obstacle for the LEC. Indeed, if the ‘equipment’ also encompasses the game itself, it is impossible to argue that Riot Games does not hold a monopoly over the supply of LoL. Moreover, Riot Games has made and continues to support LoL in order to make money. In analysing this opinion, Abanazir explains the core issue well: “e-sport competitions based on video games created for purely consumption purposes and organised by persons aimed to profit from these activities may find themselves out of the scope as they are perceived to be devoid of social function.”[15] Indeed, it can seem difficult for the LEC and LoL to argue that it has a deeper ‘social function’ but perhaps this requirement might not be completely insurmountable. An argument could be made that the e-sports aspect of LoL is not only a commercial product made for pure consumption especially because LoL is a free to play game, and Riot Games does not seem to be making any profit in its e-sport related activities. Riot Games and the LEC have also taken steps to enhance the social function of LoL by investing in regional leagues to develop local talent.

In its ruling on the Bridge case, the CJEU sidelined the AG’s approach and decided to focus on a physicality requirement. The Court, in examining the specific VAT provision, found that sport must be “characterised by a not negligible physical element,” and the fact that an activity has elements of competition, professionality and organisation were not deemed sufficient to argue that the activity is a sport for the VAT exemption.[16] Physicality was the central criteria in the CJEU’s interpretation of the concept of sport, but in doing so, it did not give any further clarity as to the threshold of physicality required for an activity to benefit from the VAT sport exemption. It has already been contended above that LoL does have a clear physical element which is intrinsically connected to the game’s skill, yet the question remains whether the physicality would be considered more than negligible by the CJEU.

In summary, if LoL and the LEC were to be examined under the VAT Directive sport exemption, it would be confronted with several challenges. The approach endorsed in the AG’s opinion would have been the most problematic since LoL is mainly a commercial product designed to attract consumers and ultimately profit a private company. However, the CJEU chose to focus its interpretation of the concept of sport on a physicality criterion. This decision may give the LEC a wide enough window to argue that the fine motor skills involved in LoL are enough to fulfil this condition.

5.     Conclusion

In its current form, the LEC would not be able to benefit from the sport exemption in the VAT Directive, but this is just one provision of EU law, and there could be other opportunities where it could attempt to claim to be a sport. In the meantime, this gives an opportunity to Riot Games to continue to develop and emphasise the social function of its e-sports competitions, which might entail building a not-for-profit entity to run the competition and to strengthen the redistribution of economic gains to the grassroots. In any case, LoL and the LEC share many characteristics with established sports, but it remains to be seen if this will be enough to boost its recognition as a ‘real’ sport in law and society.
