<P> The court's 7--2 decision held that the First Amendment applied to public schools, and that administrators would have to demonstrate constitutionally valid reasons for any specific regulation of speech in the classroom . The court observed, "It can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate ." Justice Abe Fortas wrote the majority opinion, holding that the speech regulation at issue in Tinker was "based upon an urgent wish to avoid the controversy which might result from the expression, even by the silent symbol of armbands, of opposition to this Nation's part in the conflagration in Vietnam ." The Court held that for school officials to justify censoring speech, they "must be able to show that (their) action was caused by something more than a mere desire to avoid the discomfort and unpleasantness that always accompany an unpopular viewpoint," that the conduct that would "materially and substantially interfere with the requirements of appropriate discipline in the operation of the school ." The Court found that the actions of the Tinkers in wearing armbands did not cause disruption and held that their activity represented constitutionally protected symbolic speech . </P> <P> Justices Hugo Black and John M. Harlan II dissented . Black, who had long believed that disruptive "symbolic speech" was not constitutionally protected, wrote, "While I have always believed that under the First and Fourteenth Amendments neither the State nor the Federal Government has any authority to regulate or censor the content of speech, I have never believed that any person has a right to give speeches or engage in demonstrations where he pleases and when he pleases ." Black argued that the Tinkers' behavior was indeed disruptive and declared, "I repeat that if the time has come when pupils of state - supported schools, kindergartens, grammar schools, or high schools, can defy and flout orders of school officials to keep their minds on their own schoolwork, it is the beginning of a new revolutionary era of permissiveness in this country fostered by the judiciary ." </P> <P> Harlan dissented on the grounds that he "(found) nothing in this record which impugns the good faith of respondents in promulgating the armband regulation ." </P> <P> Tinker remains a viable and frequently cited Court precedent, though subsequent Court decisions have determined limitations on the scope of student free speech rights . In Bethel School District v. Fraser, a 1986 case, the Supreme Court held that a high school student's sexual innuendo--laden speech during a student assembly was not constitutionally protected . Though Fraser applies the Tinker test of disruption to school decorum, if not undermining of educational mission, the effect is to make an exception to Tinker for "indecent" speech . Hazelwood v. Kuhlmeier, where the court ruled that schools have the right to regulate, for legitimate educational reasons, the content of non-forum, school - sponsored newspapers, also limits Tinker's application . The Court in Hazelwood clarified that both Fraser and Hazelwood were decided under the doctrine of Perry Education Association v. Perry Local Educators Association . Such a distinction keeps undisturbed the Material Disruption doctrine of Tinker, while deciding certain student free speech cases under the Nonpublic Forum doctrine of Perry . In Morse v. Frederick, the so - called "Bong Hits For Jesus" case of 2007, the Court held that schools may, consistent with the First Amendment, restrict student speech at a school - sponsored event, even those events occurring off school grounds, when that speech is reasonably viewed as promoting illegal drug use . In 2013, the full U.S. Court of Appeals for the Third Circuit re-heard a case en banc that had been argued before a panel of three of its judges, considering whether middle school students involved in a charitable effort--a breast cancer awareness drive--could be prohibited from wearing bracelets imprinted with "I ♥ Boobies! (Keep a Breast)". The Third Circuit cited Tinker when ruling that the school's ban on the bracelets violated the students' right to free speech because the bracelets were not plainly offensive or disruptive and were speech conducted to raise awareness of a social issue . The Supreme Court later declined to take up the case . </P>
