Chiles said she believes that “at the end of this journey, the people in control will do the right thing”.
USA Gymnastics attempted to have Cas reconsider its decision that led to Chiles being stripped of her medal, citing new video evidence it said proved the challenge was made in time. But on Monday, it revealed that request had been denied.
“I had confidence in the appeal brought by USAG, who gave conclusive evidence that my score followed all the rules. This appeal was unsuccessful,” Chiles said on Thursday.
On Monday, USA Gymnastics (USAG) said it “strongly disagrees” with Cas’ detailed decision.
Chiles added on Thursday: “I will approach this challenge as I have others – and will make every effort to ensure that justice is done.”
The women’s floor final took place on 5 August and Romania appealed to Cas the following day. USA Gymnastics said it did not become aware of the case until 9 August, which it said was two days past the deadline to submit objections related to panellists.
USA Gymnastics claimed this was because Cas sent case filings to “incorrect email addresses”.
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.
USA Gymnastics has said it will “pursue these and other matters upon appeal” as it continues to “seek justice for Jordan Chiles”.
