Halep, 32, submitted the legal complaint in the Supreme Court of the State of New York on Thursday, with Quantum Nutrition – also operating as Schinoussa Superfoods – and other unnamed individuals listed as defendants. The two-time grand slam winner tested positive for the banned substance roxadustat – which is listed on the 2022 World Anti-Doping Agency Prohibited List – at the 2022 US Open.
The International Tennis Integrity Agency has said Halep’s suspension is backdated and will run from October 7, 2022, until October 6, 2026. Halep was charged by the agency with two separate breaches of the Tennis Anti-Doping Programme. Along with testing positive for roxadustat, Halep was charged with irregularities in her Athlete Biological Passport , which is designed to monitor an athlete’s selected biological variables over time.
