Whether students' wearing of black armbands to express opposition to the Vietnam War was protected expression under the First Amendment.
Holding
Yes. The armbands were protected symbolic expression closely akin to pure speech.
Reasoning
Wearing a black armband to communicate opposition to the Vietnam War was a symbolic act intended to convey a particular political message. The Court treated it as closely akin to pure speech because the students' expression was silent, passive, and unaccompanied by disruptive conduct.
Students and teachers retain First Amendment rights in public schools, although those rights must be applied with attention to the special characteristics of the school environment. A public school is a state institution, and school officials must exercise their substantial authority within the limits imposed by the Bill of Rights.
The protected sphere of student expression is not confined to formal classroom discussion. Students may express opinions in school settings such as cafeterias, playing fields, and campus areas during school hours, so long as their expression does not materially disrupt school operations or invade the rights of others.
