Should the Stewards determine that there is more than one incident of interference in a race where disqualification is warranted, the Stewards shall deal with the incidents in the order in which the incident occurs during the race from start to finish; except in the case where the same horses are involved in multiple incidents. Once a horse has been disqualified, it should remain placed behind the horse with which it interfered. The Stewards shall make a conscious effort to place and maintain as placed, every and all horses placed behind others for interference.
