Sun yang eight year ban for chinese olympic champion

You're referring to Sun Yang, the Chinese Olympic champion swimmer who was banned for 8 years by the Court of Arbitration for Sport (CAS) in February 2020.

Here's a brief summary of the case:

• In September 2018, Sun Yang was involved in a controversy at a doping control test in Hangzhou, China. He was tested for a second time after an initial sample was taken, and he refused to provide a blood sample, citing concerns about the testing procedure.
• The World Anti-Doping Agency (WADA) filed a complaint with the CAS, alleging that Sun Yang had committed an anti-doping rule violation by refusing to provide a sample.
• In November 2019, the CAS panel ruled that Sun Yang had indeed committed an anti-doping rule violation and imposed an 8-year ban on him, which would have ended in 2028.
• However, Sun Yang's legal team appealed the decision to the Swiss Federal Tribunal, which in February 2020 upheld the 8-year ban.

The CAS panel's decision was based on several factors, including:

• Sun Yang's refusal to provide a blood sample, which was deemed to be a serious violation of anti-doping rules.
• The panel's finding that Sun Yang had not provided a valid reason for refusing the sample, despite his claims of concerns about the testing procedure.
• The panel's conclusion that Sun Yang had a history of non-compliance with anti-doping rules, including a previous incident in 2014 where he was banned for 3 months for missing a doping test.

The 8-year ban effectively ends Sun Yang's competitive swimming career, as he would have been 35 years old by the time the ban was set to expire.
