If you think the AMHA rule should be changed, please write up the rule change proposal (form is on the AMHA web site) and get it submitted before our November board meeting.
Please be careful how you word it, write it up as it should be in the rule book, and please include a note describing your intent of the rule change, and a contact number. Sometimes these rule change proposals are so vague and we can't contact the person submitting them so we have to reject them as it is not our place to guess the intent and re-write the proposals. Also, think carefully. I as an ammy have shown a trainers client horses in championships for him. It was that or the horses don't go in. I received no money, he did. If you limit that activity to pros only, then a lot of horses will not get in to the championship classes because there aren't enough trainers to go around sometimes as they have their own client horses in the classes.
On the other issue, per the rule book, if you think this is a rule violation, a protest needs to be filed so AMHA can then follow due process.
