An authorised officer of Horse Racing Ireland decides on the deduction required, if any, on a withdrawn horse. These deductions are decided upon using Tattersalls Rule 4c.
In the case of bets made at a price on the day of the race, before it has been officially notified that a horse has been withdrawn prior to coming under starter's orders or has been declared "not to have started", the liability of a layer against any horse remaining in the race, win or place, will be reduced in accordance with the following scale depending on the odds current against the withdrawn horse at the time of such notification:
If the current odds are:
3/10 or longer: |           |  |      | by €0.75 in the € |
2/5 to 1/3: |  |  |  | by €0.70 in the € |
8/15 to 4/9: |  |  |  | by €0.65 in the € |
8/13 to 4/7: |  |  |  | by €0.60 in the € |
4/5 to 4/6: |  |  |  | by €0.55 in the € |
20/21 to 5/6: |  |  |  | by €0.50 in the € |
Evens to 6/5: |  |  |  | by €0.45 in the € |
5/4 to 6/4: |  |  |  | by €0.40 in the € |
13/8 to 7/4: |  |  |  | by €0.35 in the € |
15/8 to 9/4: |  |  |  | by €0.30 in the € |
5/2 to 3/1: |  |  |  | by €0.25 in the € |
10/3 to 4/1: |  |  |  | by €0.20 in the € |

In the case of two or more horses being withdrawn before coming under starter's orders, the total deductions shall not exceed €0.75 in the €.
In the case of withdrawals in reformed markets, the total deduction over the two or more horses (i.e. on in the original and one in the reformed market) will be calculated on the prices applicable in the original market.
