Former British tennis player Tara Moore has filed a $20 million lawsuit against the Women's Tennis Association (WTA), alleging negligence in failing to warn players about the risks of meat contamination that led to her four-year doping ban. The Professional Tennis Players Association (PTPA), a breakaway union, is now publicly backing Moore's legal challenge against the WTA, further escalating tensions in the sport's ongoing power struggle.

Why it matters

This case highlights the growing divide between players and governing bodies in professional tennis, with the PTPA's support of Moore's lawsuit signaling a deepening civil war. It also raises questions about the fairness and transparency of doping enforcement, with Moore arguing that some players have received more lenient penalties for similar contamination incidents.

The details

In June 2022, Moore tested positive for banned substances boldenone and nandrolone at a tournament in Bogotá. She has consistently denied doping, and an independent tribunal in 2023 found that contaminated meat was the likely cause. However, an appeal by the International Tennis Integrity Agency (ITIA) to the Court of Arbitration for Sport (CAS) resulted in a reinstatement of her original four-year ban in 2025. Moore's lawsuit claims the WTA failed to adequately warn players about the risks of meat contamination, particularly ahead of the Bogotá event, and that the doping enforcement system has shown favoritism toward more prominent players.

  • In June 2022, Moore tested positive for banned substances at a tournament in Bogotá.
  • In December 2023, an independent tribunal found that contaminated meat was the likely cause of Moore's positive test.
  • In 2025, the CAS reinstated Moore's original four-year ban after an appeal by the ITIA.
  • In July 2025, the CAS ruled that Moore's elevated nandrolone levels were not sufficiently proven to be accidental.
  • In 2026, Moore filed a $20 million lawsuit against the WTA, alleging negligence and uneven doping enforcement.
