All objections shall be made to the judges and may be withdrawn only with permission of the judges. Objections relating to a horse engaged in a race may be made by the owners, trainers, driver-trainers of other horses engaged in the race or by the officials of the meeting. All objections, except claims of foul or interference during a race, must be written and lodged with the judges, prior to the start of the race in question. If the objection should prove to be frivolous or vexatious the judges may require payment of the expense of investigation unless the commission relieves the objector of this expense. All payments required to cover the expenses in investigation of the objection shall be treated in the same manner as fines as specified by rule 3769-17-36 of the Administrative Code.
