Journalists work as Chinese three-time Olympic swimming champion Sun Yang (on the screen) attends a public hearing in the Court of Arbitration for Sport (CAS) in Montreux, Switzerland on Nov. 15, 2019, after the World Anti-Doping Agency (WADA) appealed against Sun Yang and FINA over FINA's previous decision in favor of Sun on his alleged anti-doping rule violations. On December 24, the Swiss Federal Tribunal set aside a previous ruling by the Court of Arbitration for Sport (CAS) to ban Chinese swimmer Sun Yang for eight years and ordered the case back to the CAS to render a new award. In February, CAS found the three-time Olympic champion guilty of refusing to cooperate with sample collectors during a visit to his home in September 2018. The World Anti-Doping Agency brought the case to the CAS after the world swimming governing body FINA had issued Sun Yang a warning. (Photo by Alain Grosclaude/Xinhua)
