Queensland trainer Liam Birchley has been cleared over the “Aquanita eight” doping case, but three other trainers including Robert Smerdon have lost their appeals against their disqualifications.

The Victorian Civil and Administrative Tribunal on Friday found Birchley not guilty, but confirmed the guilty findings against Smerdon, Tony Vasil and Stuart Webb.

Eight people associated with thoroughbred management company Aquanita Racing were disqualified over the conspiracy to cheat in more than 100 races over seven years, using top-ups of sodium bicarbonate and Tripart paste.
