At stake in a second CAS hearing would be Yang’s chance to compete at the pandemic-delayed 2020 Tokyo Olympics now set for July 2021. The Swiss court ruling appears to have swung on an objection by Sun’s lawyers to the chairman of the three-judge panel, former Italian foreign minister Franco Frattini. It is even possible to overturn a CAS verdict in the federal court and still lose the re-trial. When Canas went to federal court, Swiss judges ruled his right to be heard had been breached and sent back the case. Immediately, Sun said he planned to appeal to the Swiss Federal Tribunal, which is Switzerland’s highest court.
