R 431.4190 Preference.

Rule 4190. (1) Preference shall be given in all overnight races according to a horse's last previous purse race. If 2 or more horses have the same preference date, then a second preference date shall be used. If 2 or more horses have the same first and second preference dates, then the entry must be determined by lot. The preference date on a horse that has drawn to race and been scratched is the date of the race from which the horse was scratched. (2) When a horse is racing for its first lifetime start, the date of the first successful qualifying race shall be considered its preference date. However, if an overnight race has been reopened because it did not fill, all eligible horses declared in to the race before the reopening shall receive preference over horses subsequently declared, irrespective of the actual preference dates.
