American gymnast Jordan Chiles must return the bronze medal she won in the Paris Olympics floor exercise after sport’s highest court said her score was judged improperly, the International Olympic Committee confirmed Sunday.

The IOC announced early Sunday it was reallocating the bronze from Monday’s women’s floor final to Romanian Ana Barbosu after the International Gymnastics Federation (FIG) said Saturday night it would respect the court’s decision and elevate Barbosu to third.

The decision came less than 24 hours after the Court of Arbitration for Sport voided a scoring appeal made by Team USA coach Cecile Landi during the competition that had vaulted Chiles onto the podium.

CAS ruled Saturday that the on-floor appeal by Landi to have 0.1 added to Chiles’ score came outside the 1-minute window allowed by the FIG. The ad hoc committee wrote that Landi’s inquiry came a minute and four seconds after the score was posted.

The IOC said in a statement it will be in touch with the US Olympic and Paralympic Committee regarding the return of Chiles’ bronze and will work with the Romanian Olympic Committee to discuss a reallocation ceremony honouring Barbosu.

CAS wrote Saturday that the initial finishing order should be restored, with Barbosu third, Romanian Sabrina Maneca-Voinea fourth and Chiles fifth.

The organization added the FIG should determine the final ranking “in accordance with the above decision,” but left it to the International Gymnastics Federation (FIG) to decide who would get the medal behind gold winner Rebeca Andrade of Brazil and silver medalist Simone Biles of the US.

The FIG said it was the IOC’s call on whether to reallocate the medal. The IOC confirmed Sunday it would respect FIG’s decision and seek to have Chiles’ medal returned.
