Teenage figure skater Kamila Valieva's case has been referred to the Court of Arbitration for Sport (CAS) after the World Anti-Doping Agency (WADA) determined it was "wrong" for her to be cleared of "fault or negligence".

Valieva tested positive for performance-enhancing drug trimetazidine on December 25, 2021, but was able to compete in the 2022 Games in Beijing at the age of 15.

The Russian was cleared to take to the ice in "exceptional circumstances", largely due to her age ensuring she was considered to be a "protected person" under WADA rules.

She won a team gold medal in Beijing and won the European Championships singles title in Tallinn last year.

In January, a Russian Anti-Doping Agency (RUSADA) disciplinary tribunal deemed Valieva – now 16 – bore "no fault or negligence" for the positive test, meaning the only sanction she faced was the disqualification of her results on the day of the initial sample collection.

WADA requested a copy of the full reasoning for further inspection and is now taking the case to CAS, believing RUSADA's decision falls foul of its code.

A statement, released on Tuesday, read: "Further to its statement of January 13, 2023, the World Anti-Doping Agency (WADA) has carefully reviewed the full reasoned decision and file related to the case of Russian Olympic Committee figure skater, Kamila Valieva.

"Accordingly, WADA considers the finding by the disciplinary tribunal of the Russian Anti-Doping Agency that the athlete bore 'no fault or negligence' to be wrong under the terms of the World Anti-Doping Code in this case and has exercised its right to lodge an appeal with the Court of Arbitration for Sport.

"Within the appeal, WADA is seeking a four-year period of ineligibility and disqualification of all the athlete's results from the date of the sample collection on December 25, 2021. As it has sought to do throughout this process, WADA will continue to push for this matter to proceed without further undue delay.

"Given the case is now pending before CAS, WADA can make no further comment at this time."
