The International Court of Sports CAS suspended Chinese swimming star Sun Yang in a four-year, three-month renegotiation. Retroactive suspension begins on February 28, 2020, Cass said. This will end the lockdown in June 2024.

The 29-year-old swimming star will miss the Olympics in Tokyo, but will be eligible to start again in Paris in 2024. However, the three-time Olympic champion Sen will be 32 by then. Previously, Sun had hoped the suspension could be reduced to two years so he could finish his career at the Asian Games in China, starting in Beijing in 2008: with notable successes in his home country, the biggest active sports champion was Hu.

Cass had Sun sentenced to an eight-year ban in February 2020 because his doping sample was destroyed with a hammer in the fall of 2018. The FINA had initially waived the ban, at which point the World Anti-Doping Agency (WADA) named Cass. Sun defended the crime by saying that the inspectors could not be sufficiently identified.

The controversial Sun newspaper, which has repeatedly been accused of doping crimes by its international competitors, is a repeat offender. Tests have already tested positive in 2014.
