Article 1 - Rules of Racing
Part 4009 - PARI-MUTUEL OPERATION
Section 4009.20 - Refund-horse excused

(1) If a horse is excused from racing for any reason whatsoever after the betting for such race has begun, the money bet on that horse shall be refunded. When the horse is part of an entry or the field, all betting upon such entry or field shall cease and all money wagered upon such entry or field shall be refunded. Notwithstanding the termination of such betting, the horse or horses in such coupled entry or field that have not been scratched shall start in the race as nonbetting interests for the purse and the finish of such horses in the race shall be disregarded for pari-mutuel purposes. The circumstances shall be announced over the public address system at the time such action is taken and thereafter as may be necessary to inform the public adequately.

(2) At a track equipped with a totalisator system with the capability to cancel and refund tickets prior to the running of a race, the time that "betting has begun" on a horse in an entry or the field shall be the time that win odds are first displayed on the track's infield tote commission on the race in which such horse is to compete (or when the probable payoff prices are posted on the first race of a multiple race pool of which such horse's race forms a part) and if a horse is scratched after such time the provisions of subdivision (a) of this section shall govern. If a horse is scratched before such time and if tickets have been sold upon an affected entry or field prior to such time the tickets shall not be refunded unless the holders thereof present them for cancellation prior to the start of the race (or the first race of a multiple pool). Tickets not presented for cancellation by such time, shall be considered as wagers upon the remaining horses in such entry or field.

(1) If a constituent horse in an entry or field is scratched or declared a nonstarter all wagers upon such constituent horse will be refunded, but wagers selecting such entry or field and wagers on the remaining constituent horses in the entry or field shall continue and be merged for odds display and payoff purposes.

(2) If all constituent horses in an entry or field are scratched and declared non-starters then all wagers on such entry or field and all wagers on such constituent horses will be refunded.
