Doseung Chung, the plaintiff, a horse player, was at Belmont Park Racetrack, which is owned by the defendant, New York Racing Association. While at the track, Chung was using a voucher to place bets on the races through an automated betting machine. After placing a bet, Chung took his betting ticket but forgot his voucher, which had thousands of dollars left on it. A few minutes later, he returned to the machine, but the voucher was gone. Chung put an electronic stop on the voucher, but the voucher had been cashed out about one minute after it was left in the machine. Chung subsequently sued the racetrack, arguing that the track was negligent in not requiring proof of identity when patrons cash out their vouchers, which constitute negotiable instruments. How did the court rule? Why?
