Though in the end, the reason they decided to reverse the decision was on the merits of the evidence itself - they looked at the new evidence, and decided she was clean,"
https://www.rt.com/sport/356063-wada-positive-drug-tests-rio/ According to Hajo Seppelt, a journalist from Germany’s premier broadcaster ARD, there were scratch marks found on urine samples from Klishina and traces of DNA from two different people were also detected in her probe tests.
https://www.rt.com/sport/355964-klishina-allowed-compete-rio/ The 25-year-old was the only Russian athlete cleared to participate in the Rio Games by the IAAF, but the federation backtracked on its decision last week after World Anti-Doping Agency investigator Richard McLaren allegedly introduced some kind of “new information” concerning the Russian athlete.
Mark - Klishina’s ban was overturned mostly because she could not be part of a Russian Federation state-sponsored doping program: she lives and trains in the USA. However, Klishina was one of the atthletes singled out - her sample bottle was alleged to bear suspicious marks and scratches, and allegedly traces of two different people’s DNA were also detected. This was first alleged in the ARD documentary.
So she was originally cleared by her association, then McLaren butted in with some ‘new evidence’. And the CAS overturned the ban again, and cleared her to compete, in spite of McLaren’s evidence. what was one of Klishina’s urine samples doing at Sochi? She’s a long jumper – is that a winter sport now? Sochi was a winter Olympics. If tampering was detected in one of her samples from somewhere else, how would that support a Russian state-sponsored doping program with the FSB fiddling the samples? Her mother claims the sample was taken at the World Championships in Moscow, in 2013. The Moscow lab run by Rodchenkov did those tests as well. But according to his testimony, the scheme of swapping the urine samples in the supposedly tamper-proof bottles was introduced at Sochi. No nice FSB man standing by at the mousehole at the Worlds in 2013.
