Training partners Gai Waterhouse and Adrian Bott have lodged an appeal against their conviction and $5000 fine on a conduct charge.
The partnership was last week found guilty of conduct prejudicial to the image of racing after an inquiry into the substitution of horses listed to gallop in a televised trackwork session.
They admitted galloping Stampede, Fabrizio and Sort After at Randwick on April 4 in place of Serena Bay, Debonairly and English but pleaded not guilty to the charge.
The gallops on the course proper were restricted to horses competing at Randwick on April 8 and all horses wore racing colours.
No date has been set for the appeal.
