Lance Armstrong's lawyers are back in court to try to stop a Dallas-based company from trying to recoup millions in bonuses.
Judge Tonya Parker will hear on Friday from lawyers for Armstrong, the disgraced cyclist who was stripped of seven Tour de France victories and given a lifetime ban from sports in 2012.
Dallas-based SCA Promotions wants to reopen arbitration about $US12 million ($A13 million) in bonuses it paid after three of Armstrong's tour victories.
But Armstrong's attorneys argue that arbitration settlement was final and can't be revisited.
Armstrong faces several lawsuits after admitting to doping.
SCA says it's entitled to reopening the settlement because Armstrong lied about taking drugs under oath.
