Bus. & Prof. Code, § 19533.5

(a) Notwithstanding Section 19533, the board may authorize the following mixed breed racing:

(1) An association licensed to conduct a quarter horse meeting to include Appaloosa races and Arabian races with the consent of the quarter horse horsemen’s organization contracting with the association with respect to the conduct of the racing meeting.

(2) A race between a quarter horse and a thoroughbred horse at a thoroughbred meeting with the consent of the thoroughbred horsemen’s organization contracting with the association with respect to the conduct of the racing meeting.

(b) Notwithstanding Section 19533, an association licensed to conduct quarter horse racing or a fair may conduct races that include paint horses racing with quarter horses or Appaloosa horses in the same race. When paint horses race with quarter horses, the consent of the organization that represents quarter horse horsemen and horsewomen shall first be obtained. A quarter horse association may write a race for paint horses only to replace an Appaloosa or Arabian race without increasing the average number of races run per race day with the consent of the organization representing the quarter horsemen and horsewomen.

(c) A quarter horse race with seven or more entries shall not be replaced by a race that includes paint horses, without the consent of the organization that represents quarter horse horsemen and horsewomen.

(d) Notwithstanding any other law, a quarter horse racing association or fair conducting barrel racing, paint horse racing, show jump racing, or steeplechase racing shall pay to the quarter horsemen’s organization the amount specified in Section 19613 for purposes of representing the horsemen and horsewomen conducting these races.

(e) Notwithstanding Section 19533, the board may authorize an association licensed to conduct a thoroughbred race meeting to include up to six nonthoroughbred races per calendar year with the consent of the organization representing thoroughbred horsemen and horsewomen, provided, however, that a nonthoroughbred race shall not be held when a fair in the northern zone is conducting a race meeting without that fair’s consent. Notwithstanding subdivision (b) of Section 19617.8, amounts deducted and distributed pursuant to this chapter from wagering on nonthoroughbred races authorized pursuant to this section shall be deducted and distributed as if the wagers were placed on a thoroughbred race.
