“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,” said USA Gymnastics in a statement.
During the final, Chiles, 23, was upgraded from fifth to third following an inquiry by her coach Cecile Landi that increased her difficulty rating.
The Romanian Olympic Committee successfully appealed to Cas on the grounds the inquiry was “untimely” as it had been submitted four seconds after the time limit of one minute.
On Sunday, USA Gymnastics submitted a letter and video to Cas appearing to show Landi’s request to file an inquiry was submitted 47 seconds after the publishing of the score, while they also said she filed a second statement 55 seconds after the original posting of the score.
Responding to Cas denying their request, USA Gymnastics said they will continue to press to “ensure the just scoring, placement and medal award for Jordan”.
“We are deeply disappointed by the notification and will continue to pursue every possible avenue and appeal process, including to the Swiss Federal Tribunal,” they added.
