A high school student with “oppositional defiant disorder” who was banned from the prom, senior trip and commencement for tweeting a vulgar comment about the principal claims disability discrimination as well as a First Amendment violation in a federal suit.

The Sterling High School student claims her calling the principal a “pussy ass bitch” was a consequence of her psychological disorder, which causes her to have “dramatic mood swings” and “difficulty with authority,” and that punishing her violated the New Jersey Law Against Discrimination.
