The World Anti-Doping Agency has referred the case of teenage figure skater Kamila Valeeva to the Court of Arbitration for Sport.
WADA said the decision was wrong under the World Anti-Doping Code.
It is seeking a four-year ban for the 16-year-old boy.
Then 15-year-old Valeeva failed a drugs test in December 2021 when she tested positive for the banned heart drug trimetazidine.
Details of the result emerged only after she won gold in the team event at the Beijing Games in February 2022 – during which she became the first woman to do a quadruple jump at the Winter Olympics.
She was allowed to compete in the women’s singles event after the court lifted her temporary ban.
However, several falls and stumbles saw her drop from first to fourth place Enter the arena in tears.
Last month, WADA released the findings of Valeeva’s doping investigation and said it was “dismayed” by the decision to clear her.
“The World Anti-Doping Agency (WADA) has carefully reviewed the fully reasoned decision and file related to the case of Russian Olympic Committee figure skater Kamila Valeeva.” Wada said.
“Accordingly, WADA considers that the Disciplinary Tribunal of the Russian Anti-Doping Agency has found that the athlete was ‘not guilty or negligent’ under the rules of the World Anti-Doping Code in this case and has exercised its right to appeal to the Court of Arbitration for Sport.
“As part of the appeal, WADA is seeking a four-year period of disqualification and disqualification of all athletes’ results from the date of sample collection on 25 December 2021.
“As it has wished to do throughout this process, WADA will continue to urge that this matter proceed without further undue delay.”
