I presume he would sue the school board, or attempt to.
I don't know how things pan out in the UK but school board would most likely hang her out to dry. Besides if this kid went r to her house that's off school property.
Then again Britain is getting rather feminazi so I wouldn't be surprised to have them paint her as the victim or get community service. Maybe he should convert to Islam. That way he'll have a trump card over her. Muslims beat the female card in the UK..so far.
Either way this kid is now a google article. Wonder how future employers view male rape victims who may have issues working with women. By going public this kid got fucked more than one way.
