Anyone is responsible to keep on top of the regs in their business area. Same as when driving laws change, or anything else. Telling police officer that you didn't know texting was illegal is no more defence then being over ratio.

Here, if caught over numbers, you have to reduce numbers immediately. Literally call parents to come and get their child. They will make other unannounced visits over the year. If you are caught again, you are close down.

Usually, it one or two over, or over-lap but being significantly over they close down first time.
