Tara Moore is being supported by the breakaway players’ union as she looks to sue to WTA for £14.7million in damages following a four-year doping ban. The former British No. 1 doubles player has sought legal action against the association for negligence, using lawyers from the Professional Tennis Players Association’s (PTPA) legal partner in King & Spalding, as per The Guardian.

While the players’ union (PTPA), which was set up by Novak Djokovic six years ago, is not fronting Moore’s legal fees, it is reported that King & Spalding are working with her on a pro bono basis. The 33-year-old was initially suspended in June 2022 after testing positive for boldenone and nandrolone. After refuting allegations of doping, Moore was cleared by an independent tribunal in December 2023, which found that contaminated meat was the “likely source” of her positive tests.

An appeal on the International Tennis Integrity Agency’s part at the Court of Arbitration for Sport ultimately overturned that ruling, and in July 2025, Moore saw her initial four-year ban reimposed, barring the 19 months that she had already served. That ruling stated that she had not sufficiently proven that the high levels of nandrolone, which appeared on the positive test, were accidental.

It means that Moore will not be able to return to tennis until the start of the 2028 season. A media release from CAS read: “After reviewing the scientific and legal evidence, the majority of the CAS Panel considered that the player did not succeed in proving that the concentration of nandrolone in her sample was consistent with the ingestion of contaminated meat.

“The panel concluded that Ms. Moore failed to establish that the ADRV (anti-doping rule violation) was not intentional. The appeal by the ITIA is therefore upheld, and the decision rendered by the independent tribunal is set aside. The cross-appeal filed by Ms. Moore was declared inadmissible.”

In dispute of the ban, Moore is now looking to sue the WTA for negligence, arguing that the tour failed to warn players of the risk of contamination from consuming meat. The claim is also described as causing reputational and financial ruin to Moore, who also argues that the WTA failed in its duty of care for athlete protection.

Moore also alleges that the ITIA has shown leniency toward higher-profile players. For context, Jannik Sinner served a three-month ban as a result of testing positive for clostebol in 2024, while Iga Swiatek served just a month when trimetazidine showed on her tests the same year.

A spokesperson from the WTA said: “We are aware of Tara Moore’s filing in the US district court and will respond through the appropriate legal process. The arbitration was conducted by a neutral arbitrator, and there is no basis to vacate the arbitrator’s award. We respect the judicial process and will not comment further while the matter is pending.”
