You can read more about it here:

Essentially though, Mt Healthy schools are withholding the diploma of a student because his family 'cheered to long' at his graduation. In order to be given his diploma, the superintendent is trying to require the student and/or his family members to do 20 hours of community service.

Sorry, but this is a power trip of epic proportions by the superintendent. Punishing the kid for something that he did not do, then attempting to require non-students to do something? What a joke. You aren't the law, lady. Kick them out of the graduation, sure. Attempt to require them to do community service? You are crazy.
