New Event! Zoom In on Transnational Sports Law - Blake Leeper v. IAAF - 4 December at 4pm (CET)

The Asser International Sports Law Centre in collaboration with Dr Marjolaine Viret is launching a new series of zoom webinars on transnational sports law: Zoom In. The first discussion (4 December at 16.00) will zoom in on the recent arbitral award delivered by the Court of Arbitration for Sport (CAS) in the Blake Leeper v. International Association of Athletics Federations (IAAF) case.

In this decision, reminiscent of the famous Pistorius award rendered a decade ago, the CAS panel ruled on the validity of an IAAF rule that places the burden on a disabled athlete to prove that a mechanical aid used to compete in IAAF-sanctioned competitions does not give them an overall competitive advantage. While siding with the athlete, Blake Leeper, on the burden of proof, the CAS panel did conclude that Leeper’s prosthesis provided him an undue advantage over other athletes and hence that the IAAF could bar him from competing in its events.

To reflect on the key aspects of the decision and its implications, we have invited scholars with different disciplinary backgrounds to join the zoom discussion.

Pistorius revisited: A comment on the CAS award in Blake Leeper v. IAAF - By Marjolaine Viret

On 23 October 2020, a panel of the Court of Arbitration for Sport (‘CAS’) rendered an award in the matter opposing Mr Blake Leeper (‘Mr Leeper’ or ‘the Athlete’) to the International Association of Athletics Federation (‘IAAF’).[1] The CAS panel was asked to make a ruling on the validity of the IAAF rule that places on a disabled athlete the burden to prove that a mechanical aid used to compete in IAAF-sanctioned competitions does not give such athlete an overall competitive advantage.

The award is remarkable in that it declared the shift of the burden of proof on the athlete invalid, and reworded the rule so that the burden is shifted back on the IAAF to show the existence of a competitive advantage. Thus, while the IAAF won its case against Blake Leeper as the panel found that the sport governing body had discharged its burden in casu, the outcome can be viewed as a victory for disabled athletes looking to participate in IAAF-sanctioned events. It remains to be seen how this victory will play out in practice. Beyond the immediate issue at stake, the case further presents an illustration of how – all things equal – assigning the burden of proof can be decisive for the real-life impact of a policy involving complex scientific matters, as much as the actual legal prerequisites of the underlying rules.

This article focuses on some key aspects of the award that relate to proof issues in the context of assessing competitive advantage. Specifically, the article seeks to provide some food for thought regarding burden and degree of proof of an overall advantage, the contours of the test of ‘overall advantage’ designed by the CAS panel and its possible bearing in practice, and potential impact of the ruling on other areas of sports regulations such as anti-doping.

The award also analyses broader questions regarding the prohibition of discrimination in the regulation of sports, as well as the interplay with international human rights instruments such as the European Convention on Human Rights (‘ECHR’), which are not explored in depth here. More...
