Latest update is CAS declines to hear additional evidence.
USA Gymnastics officials said an arbitration panel won't reconsider a decision asking gymnast Jordan Chiles to return the bronze medal she was awarded in the floor exercise at the Paris Olympics.
"USA Gymnastics was notified by the Court of Arbitration for Sport (CAS) on Monday that their rules do not allow for an arbitral award to be reconsidered even when conclusive new evidence is presented," USA Gymnastics said in a statement.
"We are deeply disappointed by the notification and will continue to pursue every possible avenue and appeal process, including to the Swiss Federal Tribunal, to ensure the just scoring, placement, and medal award for Jordan."
The IOC said in a statement it will be in touch with the United States Olympic & Paralympic Committee regarding the return of Chiles' bronze and will work with the Romanian Olympic Committee to discuss a reallocation ceremony honoring Barbosu.
The appeal could go to Switzerland's highest court, the Swiss Tribunal, or the European Court of Human Rights.
