The California Horse Racing Board is seeking written public response prior to April 10 on its proposal to eliminate the coupling of horses as single-wagering interests due to common ownership.Specifically, the actions would repeal Rules 1606 and 1974 to eliminate the coupling requirement. Rule 1606 (Coupling of Horses) states: "Two or more horses shall be coupled as a single wagering interest and as an entry when such horses are owned in whole or in part by the same person or persons."Rule 1974 (Wagering Interest) states: "A wagering interest may be any one horse in a race, or may be two or more horses coupled as a single wagering interest as an 'Entry' or the 'Field.' A declaration or withdrawal of one horse from a wagering interest which consists of more than one horse shall have no effect on any wagers made on such wagering interest."The CHRB approved the proposed rule changes for a 45-day public notice period, which began Feb. 24. Written comments should be submitted to Harold Coburn either by e-mail (HaroldA@chrb.ca.gov) or regular mail to the CHRB, 1010 Hurley Way, Suite 300, Sacramento CA 95825.Following the notice period, the CHRB will conduct a public hearing on the proposed changes during the April 27 monthly commission meeting at Hollywood Park in Inglewood at which interested parties may provide testimony.
