(a) A person who has a valid claim to a horse becomes the owner of the horse when the horse steps on to the racetrack for the race. A claim shall be voided and ownership of the horse retained by the original owner if:(1) the horse dies on the racetrack or is euthanized by a Commission Veterinarian before leaving the racetrack, either on the race surface or in the equine ambulance.(2) the horse has a musculoskeletal injury that requires loading in the equine ambulance for safe removal from the track. This claim is only voided after proper Veterinary examination of injury and the on duty Commission Veterinarian is contacted and approves of euthanasia. Horses euthanized without Veterinarian examination and notification to the attending Commission Veterinarian will not be entitled to a voided claim.(b) Horses vanned off the track for medical conditions (including but not limited to EIPH, Myositis, heat stress, extreme exhaustion) will not be treated as a voided claim.(c) On the day claimed, a claimed horse runs in the interest of and for the account of the owner from whom the horse was claimed.
