Aries, even if they arent allowed on the vaad (I dont think the prinipals are on the vaad) it doesnt cure the situation.
If a school doesnt want to follow the vaad what control do they have to force it?
Supposedly Lakewood has the strongest vaad but even there I doubt they can force their will.
Monsey unlike some other places isnt a town “run” by a Rebbe,yeshiva or single Rov but rather a group of neighborhoods and their Rabbonim combined into a mostly nice community.
