Explained: Why British tennis player Tara Moore has filed a $20 million lawsuit against the WTA over her doping suspension

Veteran British tennis player Tara Moore is no longer staying quiet. After years of fighting to clear her name, the 31-year-old has now launched a $20 million lawsuit against the WTA, accusing the governing body of women’s tennis of negligence that she says derailed her career. The move has instantly become one of the most talked-about stories in tennis news, not just because of the legal claim but because of what it says about the sport’s anti-doping system.

Why Tara Moore is taking the WTA to court

Fans have followed Moore’s case since 2022, when she was provisionally suspended after testing positive for boldenone and nandrolone. At the time, she was one of Britain’s top doubles players on the WTA Tour. What followed was a long and public battle that split opinion across the tennis world. Now, with her four-year ban officially reinstated and her comeback hopes crushed again, Moore is turning her focus toward the organisation she believes failed her.
According to her legal team, Moore’s lawsuit argues that the WTA did not warn players about the risks of eating contaminated meat while competing in Bogotá, Colombia. Her positive test came in April 2022 during a tournament there. In December 2023, an independent panel ruled she was not at fault, accepting that the banned substances entered her system through contaminated meat.
However, the International Tennis Integrity Agency appealed that ruling to the Court of Arbitration for Sport. CAS later sided with the ITIA and reinstated Moore’s original four-year suspension beginning July 2025, with 19 months deducted for time already served. Her case summary states, “The action, brought by King & Spalding and Reeves & Weiss, claims the WTA failed to warn athletes about contaminated meat risks in Bogotá, Colombia, leading to the player’s positive steroid test in April 2022, despite issuing similar warnings for other locations," Moore’s case summary against WTA reads.
After learning her ban would stand, Moore turned to social media, sharing her frustration directly with fans in what quickly became a viral moment on Instagram. “To be innocent and to have to prove that is an incredibly gruelling process. Firstly, you are trying to figure out what these things are; secondly, you are figuring out how and why these things got into your system," Moore said.
She did not stop there. “The anti-doping system is broken. I am proof of this. Not for me, as it is too late, but for future players who find themselves in this unfortunate situation. I have so much more to say when the time is right," Moore added.
The lawsuit raises questions about who is to blame and whether players are properly warned and protected on tour.
