Most recently, the admissibility of polygraph evidence was considered before CAS during the International Cycling Union and World Anti-doping Agency cases against Contador following a positive test for clenbuterol during a rest day on the 2010 Tour de France. Contador sought to voluntarily admit expert evidence on the results of a polygraph test in an attempt to prove that he had not ingested the substance intentionally.
Contador, of his own accord, underwent a polygraph examination, the results of which were analysed by Dr Louis Rovner, an experienced polygraph examiner who claimed accuracy levels of 95%. Dr Rovner’s analysis concluded that Contador was telling the truth when stating he did not undergo a transfusion in order to benefit from clenbuterol. Importantly, Dr Rovner’s conclusion was then verified by Dr John Palmatier, an independent polygraph credibility consultant.
Lie detection is regularly used in Deep Sea Fishing and Natural Body Building competitions. That said, there is no legal reason that any event organizer couldn’t ask (it would have to be included in the application) for the 1st, 2nd and 3rd place finishers to take a lie detector test. That way introducing a further level of credibility to your event.
