(1) A horse may not be considered nominated or scratched out of an engagement until the owner, trainer or designee provides written notice to the racing secretary before the time set by the association.

(2) For stake races, if a horse is not named through the entry box before the close of entries for that race, the horse is automatically out.

(3) If the validity of any nomination is alleged, the complainant must provide satisfactory proof of the error that is alleged; otherwise, the nomination will be accepted.

(4) Any owner, trainer, or designee who has entered a horse will be allowed the right to scratch the horse from the race entered prior to the published scratch time, until no fewer than eight interests remain in the race. If there are more requests to scratch than are available, permission to scratch must be decided by lot. However, in all races involving the daily double, no entry may be scratched that would reduce the starting field to less than the number designated by the racing secretary, without permission of the board of stewards. No other entries will be excused as provided above except upon receipt of a veterinarian's certificate of unfitness, change of track conditions since time of entry or other causes acceptable to the board of stewards.

(5) The racing secretary is authorized to accept entries that will be allowed to scratch based upon predetermined conditions established by the racing secretary at entry time.

(6) All horses must be scratched by the designated scratch time set by the association, and consistent with subsection (1) of this section.

(7) If the racing secretary does not designate a scratch time, no horse will be allowed to scratch without permission of the board of stewards.

(8) The scratch of a horse out of an engagement is irrevocable.
