Darya Klishina was on the outside looking in at the 2016 Rio Olympics. Russian track and field athletes (including Klishina) were ineligible to compete unless they could prove they were clean after the Russian track and field federation was suspended. Klishina hired GSA to represent her in a last-minute appeal to the Ad Hoc Division of the Court of Arbitration for Sport in Rio. With the world watching, GSA successfully proved that Klishina was clean under the governing rules of the international track and field federation. The CAS ruling enabled Klishina to be the only Russian track and field athlete to compete in the Rio Olympics.
