A recent graduate of Pembroke Pines Charter High filed a lawsuit against the school's principal for allegedly violating her First Amendment rights, after she was suspended for posting negative comments on the Internet about a teacher.

The American Civil Liberties Union filed the lawsuit Monday in federal court, on behalf of Katherine Evans, 18, of Pembroke Pines.

The drama began in November 2007 when Evans, a senior at the school, created a Facebook page that criticized her Advanced Placement English teacher, Sarah Phelps, as "he worst teacher I've ever met.''

Evans, who also posted a yearbook photo of Phelps, sought comments from other students to express their ''feelings of hatred'' toward the teacher.

Three of her classmates posted comments -- praising Phelps and chiding Evans.

''Mrs. Phelps is one of the most amazing teachers I've ever had and there's plenty of people who agree with me,'' one student wrote. "Whatever your reasons for hating her are, they're probably very immature.''

Two days after posting the information, Evans took it down on her own free will.
