Is the school fair about the way they punish the kids who fight?

My 12 y o. daughter got into a fight with another girl who had been haring her for quite a while. Finally she got tired of it and faught the girl. Well my daughter beat her and then stood up and kicked her.As the other girl lay on the ground another girl came and kicked also since she was also tired of the girls crap. Since they both got in trouble for kicking her they both went to juvi and they had to strip and where kept for a day and now they are both on probation and have to go to court for ault causing bodily injury cl A. The girl who had been haring them and had also push my daughter and called the house talking mess didn't get into any trouble at all. All 3 girls range from 12-14 in age. Was it fair that they made them strip in Juvi without my permission?
