During the women's floor exercise final at the 2024 Paris Olympics, Jordan Chiles of the United States initially finished in fifth place. However, her coach filed an inquiry regarding her difficulty score, which resulted in Chiles being awarded an additional tenth of a point, moving her into third place and earning her the bronze medal.

Romania, whose gymnasts Ana Barbosu and Sabrina Maneca-Voinea finished fourth and fifth respectively after the inquiry, protested the decision, claiming that Chiles' inquiry was filed too late. The Court of Arbitration for Sport (CAS) agreed with Romania's protest and vacated Chiles' inquiry, officially revising her score and placing her back in fifth place.

As a result, the International Olympic Committee (IOC) announced that it would reallocate the bronze medal to Ana Bǎrbosu. However, USA Gymnastics has challenged the CAS ruling, submitting video evidence that allegedly proves Chiles' inquiry was filed within the allowed time frame.

CNN reports that the CAS does not have authority to revisit the case.

A CAS Bulletin published in 2011 explores the issue of CAS appeals in more detail in the section "Appeals against Arbitral Awards by the CAS", starting on page 19 (pdf page 22). The section describes that CAS appeals are heard by the Swiss Federal Tribunal, which is essentially the supreme court of Switzerland, the particular conditions under which an appeal is typically heard, and says the following about the frequency and success of appeals:

Nowadays the CAS assumes that an appeal will be filed against approximately 10% of its arbitral awards. However, the success rate of these appeals is low. Since the CAS was established in 1984 only five appeals against CAS arbitral awards have succeeded. On average only 1% of all appeals against CAS arbitral awards were successful in 2009 and 2010. If one expresses the number of successful appeals as a percentage of all of the arbitral awards that have so far been delivered by the CAS (1984 – 2010), the success rate is 0.3%.
