Seymour trainer Michael Quadara is awaiting penalty after being found guilty of riding his horse into another horse and rider at the Victorian racetrack.

Quadara pleaded not guilty to a Racing Victoria stewards charge of misconduct or improper conduct.

The Racing Appeals and Disciplinary Board heard that on December 1, 2018, Quadara was riding a horse on the fibre-sand at Seymour racetrack when he rode his mount towards an oncoming horse, ridden by trainer Don Dwyer, forcing Dwyer to take evasive action.

"There is a history of bad blood between yourself and Mr Dwyer, and indeed there is an Intervention Order in place as between the pair of you," the RAD Board said.

"It is alleged that what you did was dangerous, with the potential to harm riders and horses.

"We find that what you did was dangerous and grossly negligent. We are reluctant to find that it was your intention deliberately to gallop into Mr Dwyer's horse, although Mr Dwyer is of that view.

"That was likely to have been a catastrophe for both horses and possibly riders.

"At the last second, Mr Dwyer was able to pull his horse out of the way, or there would have been a head-on collision."

In finding Quadara guilty, the RAD Board said it would hear the parties on penalty at a later date before handing down its decision.
