This "paddling" nonsense wasn't permitted in my GRANDPARENTS' day up here. Of course back then educators had a sense of proportion, and a menacing "don't EVER do that again" probably would suffice. Any school principal who can't verbally intimidate a 6 year old into not repeating bad behavior is in the wrong profession.
I'd make it clear that you consider physical discipline assault and battery and will react accordingly. The law may be on their side, but the national media won't be, and things could get reeeeeeally ugly. (For both of you, so decide if you want to endure it before you call it down on yourself)
This is the kind of outrageous law that only gets changed when conscientious people expose it to public ridicule.
