The decision by the Italian Anti-Doping Agency (Nado) allows Passler to compete in the Olympics, after the 24-year-old appealed her suspension.
"These have been very difficult days for me. I have always believed that I acted in good faith and I thank everyone who helped me," she said in a statement, according to NTB, adding:
"Now I can focus 100 percent on biathlon again."
Passler tested positive for the banned substance letrozole at the end of January.
Only relevant to the relay
She is not allowed to start competing again until Monday. This means that only Wednesday's relay is possible for Passler. She cannot qualify for the final mass start later next week.
Passler has participated in two relays in the World Cup this year. However, the Italian team, which has been missing one or both of its stars, Lisa Vittozzi and Dorothea Wierer, has not produced any top results. Passler is the third-best Italian in the World Cup standings, currently 33rd.
Similar to the Valieva case
However, Italy is taking a risk if she competes in the relay. If she is found guilty of doping, the team would lose the relay result.
"If it turns out that she is found guilty of having doping agents in her system, regardless of why she took them, they will lose the medals," explains Åke Andrén-Sandberg, one of Sweden's most recognized doping experts.
This is exactly what happened at the Beijing Olympics when Russian figure skater Kamila Valieva was allowed to compete while awaiting a decision. She went on to win team gold, but the neutral Russian team was later stripped of the gold medal.
Whether Passler will be given the opportunity to compete during the investigation and whether the B sample will be analyzed depends on which of two lists the substance is on.
"If it's something that's used in healthcare, you don't have to be banned immediately. If it's something that's completely unreasonable to have ingested through healthcare, then you're banned immediately," he explains.
Likely accidental
According to Nado, it is likely that she ingested the banned substance accidentally or through contamination. Passler has claimed that the positive samples must be contaminated.
Åke Andrén-Sandberg is critical:
"I've had about thirty similar cases and in half of the cases they are acquitted and in half they are convicted. There is no really good line; there is too much subjective opinion on the part of the courts."
