The lawsuit, filed Monday in a Florida federal court, concerns Katherine Evans, now 19, who was suspended as a senior last year after creating a Facebook group devoted to her English teacher. The group was called "Ms. Sarah Phelps is the worst teacher I’ve ever met!," and featured a photograph of the teacher, and an invitation for other students to "express your feelings of hatred."
After people’s comments derided Evans for the online stunt, and expressed support for the teacher, she deleted the group. But Pembroke Pines Charter High School, which did not respond for comment, suspended Evans for three days for "disruptive behavior" and for "Bullying / Cyber Bullying Harassment towards a staff member," according to the lawsuit, which is backed by the American Civil Liberties Union.
