Stewards have charged top Melbourne trainer Robert Smerdon following a raid on his stables on Caulfield Cup day.
Stewards allege Smerdon allowed the horse Shewan to be treated on the day he was due to race.
Shewan was found to have blood seeping from a puncture wound in the jugular region of his neck.
Veterinary evidence was presented in support of the stewards’ case suggesting that the wound was likely to have occurred within 30 minutes of the inspection.
Smerdon has pleaded not guilty.
The inquiry is continuing.
