Judge dismisses $800 million US lawsuit by Enhanced Games, which declines to pursue case further

A federal judge has dismissed an $800 million US lawsuit filed by the Enhanced Games alleging that World Aquatics, the World Anti-Doping Agency and USA Swimming led an illegal effort to dissuade swimmers and other athletes from competing in its new series.

U.S. District Judge Jesse Furman ruled against the sports startup in November, giving it 30 days to refile the case to address his objections. On Thursday, WADA sent out a news release announcing the deadline had passed.

"It vindicates the strong stance we have taken on this matter," WADA said in a news release.

A person with knowledge Enhanced's legal maneuverings told The Associated Press it did not refile because it has had recent success signing swimmers, and also because it does not want to complicate its recent filing for a public offering that it expects will raise around $200 million.

The person spoke on condition of anonymity because of the sensitivity of the ongoing public-offering process.

Earlier this month, Enhanced announced five more swimmers who planned to compete at its event next May, where athletes will compete for $250,000 first prizes.

They joined a field that now numbers around a dozen, including Olympic medalists James Magnussen, Ben Proud and Cody Miller. Fred Kerley is the top sprinting name set for the event, which will require strict medical observation of the athletes but will not ban drugs the way Olympics sports do.

The lawsuit centered on a rule adopted by Switzerland-based World Aquatics earlier this year that threatened to banish athletes who compete in "sporting events that embrace the use of scientific advancements or other practices that may include prohibited substances and/or prohibited methods."
