The high-profile appeal filed with the Court of Arbitration for Sport (CAS) against Sun Yang and the International Swimming Federation (FINA) cost the World Anti-Doping Agency (WADA) more than $600,000 (Â£456,000/â‚¬500,000), it has been revealed.
The figure is disclosed in WADAâ€™s newly-published 2019 annual report.
This shows that the body managed a small surplus in the year before COVID-19 struck, with income of just over $38 million (Â£28.9 million/â‚¬31.5 million), excluding financial income, all but matched by $37.8 million (Â£28.7 million/â‚¬31.4 million) of operating expenses.
The case against the three-time Olympic swimming champion and Chinese sporting icon resulted in him being banned for eight years.
His lawyers have since filed two appeals with the Swiss Federal Tribunal.Read Inside the Games
