$10 Late Fee on $50 Graduation Fee at Northwest High School

Here's a $10 late fee on a $50 charge!  That's quite a late fee!  Where has this steep late fee been authorized by the Board of Education or the Maryland legislature?  Oh, it hasn't.  
It's just a made up fee by a local principal.  There are no rules when the fees are illegal!
