Morse v. Frederick (2007)

In January 2002, the Olympic torch relay passed in front of Juneau-Douglas High School in Juneau, Alaska. The principal, Deborah Morse, allowed students to leave class to watch the relay as a school-approved event supervised by teachers. As the torchbearers and television cameras passed, senior Joseph Frederick and several friends, standing across the street from the school, unfurled a 14-foot banner that read "BONG HiTS 4 JESUS." Morse told the students to take down the banner. Frederick refused, and Morse took the banner and later suspended him. Frederick sued, arguing that the school had punished his speech in violation of the First Amendment.

In Morse v. Frederick (2007), the Supreme Court ruled 5-4 for the principal. The Court held that because the banner could reasonably be viewed as promoting illegal drug use and was displayed at a school-supervised event, the school could restrict it without violating the First Amendment.
