Kamila Valieva, a teenage Russian figure skater, has been allowed to participate in the Winter Olympics women’s competition despite having failed a drug test.

The Court of Arbitration for Sport released its ruling less than 12 hours after a hastily arranged hearing that lasted into early Monday morning that the 15-year-old Valieva, the favorite for the women’s individual gold, does not need to be provisionally suspended ahead of a full investigation. She was “protected” as a minor and thus was exempted from the rules of an adult athlete. The court ruled in her favor.

Matthieu reeb, Director General at CAS stated that “the panel considered that preventing her from competing in the Olympics would cause irreparable harm to her in the circumstances.”

Valieva, along with her Russian counterparts, can now aim to win the Olympic record for women’s figure skaters. Start the event with a short program on Tuesday, and end with a free skate on Thursday.

A panel of experts also noted fundamental problems of fairness in their decision. They cited the fact she had tested positive in Beijing, and “serious concerns of untimely notification of her positive result”.

Valieva has tested positive for the heart medication trimetazidine on Dec. 25 at the Russian nationals but the result from a Swedish lab didn’t come to light until a week ago, after she helped the Russian Olympic Committee win the team gold.

Russian anti-doping agencies immediately suspended her and lifted the ban the next day, leaving in limbo the decision to award the medals. A hearing expedited was held by IOC, others and the IOC appealed. Valieva testified via video conference.

Under-16 athletes like Valieva are entitled to more anti-doping rights and they don’t usually have to be held accountable for using banned substances. The focus of any future investigation will will home in on her personal team — coaches, doctors, nutritionists, etc.

This decision only covers whether Valieva will be allowed to keep skating after her case is decided. This ruling doesn’t affect the outcome of her one gold medal.

Valieva was the first woman to land quadruple leaps at the Olympics. She won gold in the Russian Olympic Committee’s team event on Monday.

This medal as well as any individual medal she has won could be hers.
