Homburger with U.S. gymnast Jordan Chiles before the Swiss Federal Supreme Court

Homburger represented U.S. artistic gymnast Jordan Chiles on securing revision of CAS award before the Swiss Federal Supreme Court, in connection with the athlete’s bronze medal at the 2024 Olympic Games in Paris. The Swiss firm acted as co-counsel together with international counsel Gibson, Dunn & Crutcher.

The context

At Paris 2024, Chiles had initially been awarded the bronze medal in the women’s gymnastics floor exercise final, after her coach’s inquiry resulted in an increase to her final score. However, a CAS panel subsequently ruled, that the inquiry had been submitted four seconds after the applicable one-minute time limit and was therefore invalid.

In September 2024, Homburger filed both a request for revision and an appeal with the Swiss Federal Supreme Court on behalf of the athlete. In the revision proceedings, Chiles relied on newly emerged video evidence demonstrating that the inquiry had in fact been submitted within the one-minute time limit.

On January 23, 2026, the Swiss Federal Supreme Court upheld a request for revision filed on behalf of Chiles and set aside a Court of Arbitration for Sport (CAS) award that had deprived her medal. The Swiss Federal Supreme Court granted the request for revision, set aside the CAS award and remitted the matter to the arbitral tribunal.
