It has been in place for as long as I can remember (Now the Aug 1st date used to be a different date maybe the date that the schools started can't remember for sure)

I am not aware of this rule being broken (in our area at least)

If a player were to do so then any contests he plays in would be ruled forfits.

I would be SHOCKED if any coach or AD would risk that situation.

I am wondering if the people in question realize that they will be inelegable yet?
