(3) The case that there has been no winning horse in the race in respect to the betting system concerned.
2 In the double winning system, if, after the betting ticket has been sold, the case which comes under any of the following items has occurred, such betting shall be null and void:
(1) The case that the number of starters in each of the races combined to a set in the betting has been reduced to only one, or the number of starters in any of the said races has been reduced to none;
