In Morse v. Frederick (2007), a student held up a banner with a message that seemed to promote illegal drug use at a school-supervised event. The school
principal took away the banner and suspended the student for 10 days. She
reasoned that her actions were justified by the school's policy against the display
of material that promotes illegal drug use. The student alleged that his First
Amendment rights were violated and sued the principal.
Which First Amendment provision does Morse v. Frederick (2007) have in
common with Tinker v. Des Moines Independent Community School District (1969)?
