Far from over: Sun Yang doping case goes to highest courtSports | 14 Mar 2019
The World Anti-doping Agency has gone to the Court of Arbitration for Sport to appeal against a decision to clear Chinese swimming star Sun Yang of missing a doping test.
Sun, who has won Olympic gold in the 200 meters, 400m and 1,500m freestyle, missed an out-of-competition test on September 4 at his home in Zhejiang province.
The swimmer - who was banned for three months in 2014 for taking a stimulant - was cleared of wrongdoing by world swimming governing body Fina in January, according to his lawyers.
Sun failed to comply with the test requirements but a Fina doping panel cleared him of wrongdoing because testers had breached several rules. Those included failing to produce authorization letters and a nursing license, his lawyers said.
Sun's lawyers also threatened legal action against a Britain's Sunday Times newspaper, which claimed Sun clashed with the anti-doping testers and he and a bodyguard smashed a sealed vial of blood with a hammer.
Sun is one of China's greatest-ever athletes and is hugely popular at home.
But his career has been dogged by controversy over doping suspicions and he was publicly branded a drug cheat by his Australian rival Mack Horton at the Rio Olympics in 2016.
