Horse show rules and what the heck to do!!!!?

okay so we show at the local shows and they said youth can not show stallions..so i am trying to get youth high point and you had to pick yo cles.. i chose Youth at halter and miniature halter well we just have a pasture mini and of course he isnt gonna win against some little stick leg mini's..another boy showing against me shows a stud and nothing gets said to him..should i say something because that is not fair at all..i was gonna show this georgous little mini stud but no i cant but some how the other boy can..Do you think his points should be taken for breaking the rules????
