Wearing a campaign shirt: political speech at school

In Tinker v. Des Moines Independent Community School District (1969), John Tinker, 15, his sister Mary Beth, 13, and Christopher Eckhardt, 16, wore black armbands to school to protest the Vietnam War. The district had adopted a rule against armbands and suspended them. The Supreme Court held that students do not shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.

The Court set the test that still applies. A school may restrict student expression only if it can show that the expression would materially and substantially interfere with the requirements of appropriate discipline in the operation of the school. An undifferentiated fear or apprehension of disturbance is not enough.

One detail in the opinion matters most for a campaign shirt. The Court pointed out that Des Moines schools allowed students to wear political campaign buttons and even the Iron Cross; only the anti-war armband was singled out. Banning one opinion while allowing others is exactly what the First Amendment forbids. A school that lets one candidate's shirt through the door and stops another's is doing the thing Tinker struck down.

Two later cases carve out space for the school. In Hazelwood School District v. Kuhlmeier (1988), the principal of a Missouri high school pulled two articles from the student newspaper, which was produced in a journalism class. The Court held that the students' rights were not violated, because educators may control school-sponsored expressive activities so long as their actions are reasonably related to legitimate pedagogical concerns, meaning real teaching reasons. So a candidate endorsement in the school paper, a campaign speech at a school assembly, or a slogan on the morning announcements can be edited or refused. That is the school's speech, not yours.

A shirt is different. Nobody thinks the school printed it. It is your own speech, in your own voice, and Tinker governs it.

There is a real limit on your side too. Tinker protects the message, not disruption. If the shirt carries a slur, a threat, or a lewd joke, the school can act, and if wearing it has already caused a fight or shut down a class, the school can point to that.

A school can have a dress code, and it can have a uniform. A rule that says no printed slogans of any kind, applied to every student, is a content-neutral rule, and courts generally treat it differently from a rule aimed at one message. The question to ask is whether the rule is being enforced the same way for everyone. If band shirts, sports logos, and one party's slogan all pass, and yours does not, the rule is not neutral in practice. Write down the date, the shirt, the teacher, and what other students were wearing that day.
