The US Government is seeking $US100 million ($A131 million) from former cyclist Lance Armstrong in relation to his doping controversy.
A judge approved the case to go to trial.
The US Justice Department says Armstrong defrauded the government by accepting millions of dollars from the US Postal Service in sponsorship while notching a string of Tour de France victories while doping.
Armstrong was banned for life from racing in 2012 and stripped of seven Tour titles.
He is accused of orchestrating one of the most sophisticated doping schemes in sports.
Armstrong admitted to doping in 2013 during an interview with Oprah Winfrey.
Armstrong’s former teammate, Floyd Landis, was the whistleblower and can obtain a reward if the government is successful in recouping the money.
The US Postal Service paid around $32.3 million ($42 million) to Armstrong’s cycling team, but the government has calculated damages at three times this amount.
Landis could be granted up to 25 per cent of whatever sum the government recovers.
