In all horse races where a runner is withdrawn or declared a non-runner, stakes on that selection will be refunded unless the bet was placed ante-post, in which case it will be settled as a loser. Bets on the remaining runners in that race prior to the withdrawal may be subject to a deduction. This deduction is based on Tattersalls Rule 4(c) and relates to the non-runner’s price at the time of withdrawal.
A new market may then be formed for subsequent bets. Bets on horses in subsequent markets that then have one or more horses withdrawn may have a deduction calculated on the prices applicable to that market at the time of the withdrawal.
In the event that there is insufficient time to form a new market on the race, SP bets may also be subject to a deduction based on Tattersalls Rule 4(c). For early price bets, Tattersalls Rule 4(c) deductions will be based on the market price of the withdrawn horse at the time of withdrawal.
