Banned Russian figure skater Kamila Valieva has blamed her positive doping test on a strawberry dessert prepared by her grandfather on a chopping board he used to crush his medication pills.
The Court of Arbitration for Sport on Wednesday published the 129-page detailed ruling from its three judges to explain why they imposed the four-year ban last week on Valieva, whose doping case at age 15 stunned the 2022 Beijing Olympics.
The highest court in sport had found Valieva guilty of committing an anti-doping rule violation (ADRV), following the finding of Trimetazidine (TMZ) in a sample collected from her in December 2021, during the Russian National Championships.
CAS said that in her submissions, Valieva, now 17, had asserted that the prohibited substance entered her body through the consumption of the strawberry dessert prepared by her grandfather on a board he used to crush his pills containing TMZ.
"The CAS Panel determined that this explanation was not corroborated by any concrete evidence and that the athlete was not able to establish that she had not committed the ADRV intentionally," CAS said.
"From this basis, and according to the relevant rules, the status of "Protected Person" that the Athlete could enjoy before the CAS ad hoc Division at the time of the Olympic Winter Games 2022, because of her young age and on the basis of the limited evidence which was available at the very beginning of the case, was no longer applicable in her situation."
CAS went on to say that as Valieva failed to establish that she did not commit the ADRV intentionally, and as the "No Significant Fault or Negligence" criterion was not met, there was no basis to treat her any differently from an adult athlete.
All of Valieva's competitive results since the date of the offence were voided, including the gold medal she helped the Russian Olympic Committee win in the team event at the 2022 Beijing Winter Games.
Russia said it would appeal the decision to strip it of the medal.
