British tennis player Tara Moore has suffered another blow in her years-long fight to clear her name, losing her $20 million lawsuit against the WTA Tour. A federal judge in New York upheld an earlier arbitration decision and kept her four-year doping suspension in place until the start of the 2028 season.

Moore, a former British doubles No. 1, tested positive for the banned substances boldenone and nandrolone at a WTA 250 tournament in Bogota, Colombia, in 2022. She has consistently maintained that the substances entered her system through contaminated local meat rather than intentional doping, pointing to boldenone's known link to livestock practices in the region and noting that other players have tested positive for the same substance after competing in Colombia. An independent anti-doping tribunal initially sided with Moore in late 2023, finding the positive tests likely came from contaminated meat and that she bore no fault, leading to her provisional suspension being lifted.

However, the International Tennis Integrity Agency appealed to the Court of Arbitration for Sport, which overturned that decision and reinstated the four-year ban. Moore then shifted her fight toward the WTA itself, arguing it failed to warn players about the known risk of contaminated meat in Bogota despite issuing similar warnings for Guadalajara, Mexico. She claimed that failure cost her at least $20 million in lost prize money.

An arbitrator rejected those claims last November, finding the issues had already been settled by CAS and that neither the ITIA nor the WTA owed players a duty to warn. Moore then asked a US District Court to vacate the award, but Judge Andrew Carter Jr. denied her motion, citing the strong legal presumption favouring arbitration awards and finding she received a fair hearing.

Moore reached a career-high singles ranking of 145 in 2017, reached the Wimbledon second round in 2016, and won nine ITF singles titles and 18 doubles titles. The ruling effectively ends her legal avenues in the United States, though she remains suspended until 2028. Her case has become a cautionary tale about the strict liability principle in anti-doping rules, under which athletes are responsible for whatever enters their bodies regardless of intent.

Moore's contaminated-meat defence echoed earlier cases in tennis and cycling where athletes blamed tainted food for positive tests, with mixed success before tribunals. Anti-doping authorities have long taken a sceptical view of such claims, insisting that strict liability is the only workable standard. For Moore, now 34, the end of her legal fight also raises questions about whether she can rebuild a professional career after a four-year absence from the tour, with her suspension running until 2028.
