Should they be? Why should Racing apply a higher standard (a lower conviction threshold) than higher courts?
For example a licensee could be convicted of a minor drug offence in Court, be discharged with a probationary period or fined and/or given community service. Racing then has another go at the person and often penalises them by suspending their license and thus removing their livelihood. Why?
If the Police couldn't nail a match fixing charge in the criminal court because of a lack of evidence why should the RIU/RIB (who have often acted like Keystone Cops) be able to apply some vague rules and finish the livelihood of a licensee? Or ban an owner?
We now have the ridiculous situation of where Stipes with absolutely zero experience in driving or riding a horse in a race determining whether or not a driver made the right split second decision. The driver making the wrong decision has already cost themselves but then the Stipes double down and punish them again! With no evidence of financial gain.
