A judge violated a juvenile's free-speech rights when he placed her on probation for posting an expletive-laden entry on MySpace criticizing a school principal, the Indiana Court of Appeals ruled.

"While we have little regard for A.B.'s use of vulgar epithets, we conclude that her overall message constitutes political speech," Judge Patricia Riley wrote in the 10-page opinion.

In February 2006, Greencastle Middle School Principal Shawn Gobert discovered a Web page on MySpace purportedly created by him. A.B., who did not create the page, made derogatory postings on it concerning the school's policy on body piercings.

The state filed a delinquency petition in March alleging that A.B.'s acts would have been harassment, identity deception and identity theft if committed by an adult. The juvenile court dropped most of the charges but in June found A.B. to be a delinquent child and placed her on nine months of probation. The judge ruled the comments were obscene.
