Students are now suing schools for sexual harassment. The cases raise important issues about the limits of discovery. In a case in Petaluma, California, a girl claimed that she was harassed for years and that the school knew about it and failed to act. According to press reports, she alleges that a boy stood up in class and asked, “I have a question. I want to know if [Jane Doe] has sex with hot dogs.” In discovery, the school district sought the parents’ therapy records, the girl’s diary, and a psychological evaluation of the girl. Should they get those things?
