Assessing contamination and thresholds under the World Anti-Doping Code: an advocate’s view on Lawson v IAAF (CAS 2019/A/6313)

Long Jumper
Friday, 24 April 2020 By Jonathan Taylor QC

This article is part of a series of articles by LawInSport looking from different perspectives at the important issue raised in Lawson of how contamination and relevant thresholds are addressed by the World Anti-Doping Code. 

The article is written by Jonathan Taylor QC, Bird & Bird LLP.  Jonathan was counsel to World Athletics (fka the IAAF), but not in Lawson v IAAF or any other doping cases. From November 2016 to January 2020, Jonathan was chair of WADA’s Compliance Review Committee, which works to ensure compliance by Signatories to the World Anti-Doping Code with their duties under the Code and the related International Standards.

In this article, the author examines and expresses his views on the decision reached by the panel in Lawson, and its potential implications for similar cases.  Specifically, it looks at:

  • Rebutting the Article 10.2 presumption of intent in the absence of proof of source;
  • Accepting the plea of no intent in absence of proof of origin; and
  • Accepting the No Fault plea without proper proof of source. 

A longer version of this article will also appear in the August/September 2020 edition of International Sports Law Review.
