Okla. Admin. Code § 325:60-1-25
Before the race has been declared official, a Jockey, Trainer or his/her Assistant Trainer, Owner, or the Authorized Agent of the horse, who has reasonable grounds to believe that the horse was interfered with or impeded or otherwise hindered during the running of a race or that a riding rule in this Chapter was violated by any Jockey or horse during the running of the race, may make a claim of interference or foul with the Stewards or their delegate; but such claim must be made prior to the race being declared official by the Stewards. The Stewards shall thereupon hold an inquiry into the running of the race; however, the Stewards may upon their own motion conduct an inquiry into the running of a race. Any claim of foul, objection, and/or inquiry shall be immediately announced to the public.
