Tinker v. Des Moines and the Armbands That Protect Conservative Students Too

Picture a sophomore in an Iowa high school who arrives on a Monday wearing a plain T-shirt with a small pro-life slogan on the chest. By second period she has been pulled from class. By lunch the assistant principal has told her the shirt "makes other students uncomfortable," and that she can change, go home or be disciplined. This is a hypothetical, and I label it so. But if you want to know what her best argument would be, it starts with a case about black armbands, a war on the other side of the world, and a decision handed down in 1969 by a Court that did not have this student in mind.

That is the irony I want you to enjoy. Tinker v. Des Moines was a victory for anti-war teenagers, brought with the backing of the American Civil Liberties Union's Iowa affiliate, and written by a liberal justice. Conservatives have every reason to be suspicious of the people who brought it. And conservatives should defend it with everything they have, because it is the best protection a young person of any politics has against a principal who has decided which opinions are allowed in the hallway.

December 1965

In December 1965 the United States was escalating its war in Vietnam, and public opinion at home was divided. A group of adults and students in Des Moines, Iowa, planned to wear black armbands to school to mourn the dead and to support a Christmas truce. The students included John Tinker, fifteen, his sister Mary Beth Tinker, thirteen, and Christopher Eckhardt, sixteen.

The school principals heard about the plan, and on December 14 the Des Moines school board adopted a rule that any student wearing an armband to school would be asked to remove it and, if the student refused, would be suspended until he returned without it. The three wore their armbands on December 16 and 17, and each was sent home and suspended. The students stayed away until after New Year's, when the planned period of protest ended.

Note a few facts that the later retellings leave out. The armbands were silent. No student disrupted a class, shouted, blocked a hallway or refused to learn. The Court found no evidence of disruption of classwork, only some hostile remarks directed at the wearers outside class. Five students were suspended out of roughly 18,000 in the district. The school had not banned other political symbols. Students wore buttons for political campaigns, and some wore the Iron Cross, a German military decoration that had been adopted as a fad. Only the armbands were singled out.

The families sued in federal court, represented by the Iowa Civil Liberties Union, on the ground that the suspensions violated the First Amendment. The district court ruled for the school, finding the rule reasonable to prevent disturbance. The Eighth Circuit divided evenly and let the decision stand. The Supreme Court took the case, heard argument in November 1968, and decided it on February 24, 1969.

The holding

By a vote of seven to two, the Court ruled for the students. Justice Abe Fortas wrote the opinion. It begins with a sentence that has been quoted in nearly every student speech case since:

It can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.

Fortas held that wearing an armband to express an opinion was "pure speech," closely akin to the symbolic speech the Court had protected before. He rejected the school's justification, which was the fear of disturbance. In his words, "undifferentiated fear or apprehension of disturbance is not enough to overcome the right to freedom of expression." The school had not shown that the armbands would interfere with discipline or school operations. It had shown that some people disliked the message.

The test the Court announced is the one that governs to this day. A school may restrict student expression if it can reasonably forecast that the expression will materially and substantially disrupt the work and discipline of the school, or invade the rights of others. Fortas wrote that conduct by a student, in class or out of it, that "materially disrupts classwork or involves substantial disorder or invasion of the rights of others" is not protected. Disruption is the standard. Disagreement is not.

He added a sentence about the school's role that conservatives should memorize: state-operated schools may not be "enclaves of totalitarianism." The school officials do not possess absolute authority over their students. Students are persons under the Constitution.

The dissent

Justice Hugo Black dissented, and his opinion is among the sharpest in the history of the Court. Justice Harlan also dissented, on narrower grounds. Black's objections should be read by anyone who wants to understand the other side.

Black thought the decision was an assault on the authority of local school officials. In his view the Court was putting itself in the place of school boards, and was handing control of the public schools to the judiciary. He warned that if students could defy the orders of their principals under the cover of the Constitution, then school discipline, which depends on the authority of adults, would suffer. He wrote that "It is a myth to say that any person has a constitutional right to say what he pleases, where he pleases, and when he pleases," and he pointed to the armband episode as a distraction from the business for which the taxpayers send children to school: learning.

This is a serious argument. It is the voice of a justice who believed in the constitutional order, in the reserved powers of local governments, and in the need for order in a classroom. I would not mock it. A school full of students exercising their right to say anything at any moment would be no school at all. Black's fear of judicial micromanagement was reasonable, and one can see it in the long line of later cases in which courts were asked to referee dress codes, newspaper articles and slogans.

But I think Black was wrong about Tinker, for three reasons.

1. The speech was silent and passive. The armbands did not interrupt a class. They were a quiet expression of opinion. The test the Court adopted does not allow students to say anything they like in any classroom. It requires a school that wants to restrict speech to point to a real disruption, or a reasonable forecast of one.
2. The school's rule was not neutral. Students wore other political symbols without complaint. The rule targeted one viewpoint, and the Constitution does not permit government to pick winners among opinions, even within a school. When the state favors one side, it is the state taking sides, and the students are the audience it is trying to instruct.
3. A school that teaches self-government by suppressing it contradicts itself. A civics lesson in a building where a student cannot wear an armband is a lesson in the opposite of what it claims to teach. Fortas insisted that students are persons under the Constitution. A student who learns the First Amendment by seeing it enforced learns more than one who reads about it.

Why it protects conservatives today

I said that I would make the case for conservatives, and here it is.

Tinker is a viewpoint-neutral rule. It does not say that anti-war students may speak. It says that students may speak unless they substantially disrupt the school. That means the pro-life shirt in my hypothetical gets the same protection as the black armband. So does the American flag, or a shirt that says what the student believes about marriage, or a slogan about the Second Amendment, or a Bible verse. The principal who says "that makes other students uncomfortable" is making exactly the argument Fortas rejected: an undifferentiated fear of disturbance, presented as an objection to the message.

Over the years conservative students have invoked Tinker to defend the right to wear shirts, carry flags and distribute religious literature. Some have won and some have lost, and I do not pretend that the law is uniformly on their side. But the rule is on their side. And the principle is one the Left tends to forget when it is in charge of the school: the same First Amendment that protected a Vietnam protest protects a student's expression of unfashionable beliefs.

There is a further point about the "other students" argument, which comes up so often it deserves a sentence of its own. The Tinker test protects against disruption, and it allows schools to prevent a speaker from invading the rights of others. It does not make the discomfort of an audience a reason to silence a speaker. A student who hears an opinion he dislikes has not had his rights invaded. He has been educated. The same principle governs the hecklers on a college campus, which I discuss in The Heckler's Veto on Campus and What the First Amendment Says About It.

The limits that came later

Fairness requires me to describe how the Court narrowed Tinker, because the later cases are where many disputes are decided.

Bethel School District No. 403 v. Fraser (1986). A high school student named Matthew Fraser delivered a nominating speech at a school assembly filled with sexual innuendo. The Court upheld his suspension. It held that a school may discipline lewd, vulgar or plainly offensive speech without showing substantial disruption. The case is about the manner of speech, not its viewpoint, and it rests on the school's interest in teaching the boundaries of civil discourse.

Hazelwood School District v. Kuhlmeier (1988). Students on a school-sponsored newspaper wanted to run articles on teen pregnancy and divorce. The principal removed them. The Court held that schools may exercise editorial control over school-sponsored expression, such as a newspaper or a play, so long as their actions are reasonably related to legitimate pedagogical concerns. The distinction is that the school is the speaker, in a sense, and need not lend its name to every message.

Morse v. Frederick (2007). A student unfurled a banner reading "Bong Hits 4 Jesus" across the street from his school, at a school-sanctioned event, during the Olympic torch relay in Juneau, Alaska. The Court held that schools may restrict speech they reasonably regard as promoting illegal drug use. Chief Justice Roberts wrote that the speech was not political in the Tinker sense, and Justice Alito, in a concurrence joined by Justice Kennedy, emphasized that the holding should not extend to political or social commentary.

So the rule is a family of rules. Tinker governs a student's personal expression that is not lewd, not school-sponsored and not drug advocacy. Fraser, Hazelwood and Morse are the exceptions. And in 2021, in Mahanoy Area School District v. B.L., the Court ruled 8 to 1 for a cheerleader disciplined over an off-campus Snapchat post, holding that a school's interests in regulating off-campus speech, while real, were insufficient there, which I take up in A Snapchat Post, a Cheer Squad and the Limits of School Power.

The Founding measure

The Court's habit of carrying the Bill of Rights down to the states, one right at a time, is told in How the Bill of Rights Came to Bind the States, One Right at a Time.

You will not find the word "student" in the First Amendment. You will find "Congress shall make no law... abridging the freedom of speech," and the Fourteenth Amendment carries that command to every public school board in the nation. The Founders expected citizens to speak, and expected the government to be restrained in how it answered. Madison's idea of a free republic, laid out in his argument for the Bill of Rights, depended on a people who could say what they thought without asking permission.

There is also a lesson here about the character of a free society. A school that cannot tolerate an armband is a school that does not trust its own students to hear an opinion. A school that teaches the habit of answering speech with more speech, of arguing instead of silencing, produces citizens who can handle a free country. I would hold that standard for every school, and for every viewpoint, including mine.

It is worth noticing, with respect, that the stakes of speech and violence became painfully clear to many Americans on September 10, 2025, when Charlie Kirk was killed while speaking at Utah Valley University. A society that settles disagreement with words, and protects the right to say them, is the alternative to the one that does not.

The case in brief

1. In December 1965, three Des Moines students were suspended for wearing black armbands to protest the Vietnam War, and the school's rule singled out only that symbol.
2. In Tinker v. Des Moines (1969), the Court held seven to two that students do not shed their constitutional rights at the schoolhouse gate, and that schools may restrict speech only when it materially and substantially disrupts school operations or invades the rights of others.
3. Justice Black's dissent warned of judicial supervision of discipline, a fair concern that does not answer a silent, viewpoint-specific ban.
4. The rule is viewpoint neutral, so it protects the pro-life shirt, the flag and the Bible verse exactly as it protected the armband.
5. Fraser, Hazelwood and Morse mark the limits: lewd speech, school-sponsored speech and drug advocacy.

What you can do: read your own school district's student handbook policy on dress and expression, and ask the principal's office, in writing, what standard it applies when a student's message is challenged.
