Which case upheld the rights of students to express themselves in school?

The case that upheld the rights of students to express themselves in school is Tinker v. Des Moines. This landmark decision, delivered by the Supreme Court in 1969, established that students do not lose their First Amendment rights to freedom of speech when they enter a school environment. The Court ruled in favor of students who wore black armbands to protest the Vietnam War, stating that their symbolic speech was protected as long as it did not cause a material disruption to the educational process.

This ruling is pivotal as it set a precedent for how schools must balance the rights of individuals to express their opinions while maintaining an environment conducive to education. The other cases listed deal with different aspects of law: Miranda v. Arizona pertains to the rights of defendants in police custody, New Jersey v. TLO addresses search and seizure in schools, and Brown v. Board of Education focuses on the desegregation of public schools. Each of these cases is important in its own right but does not specifically address the freedom of student expression in educational settings like Tinker v. Des Moines does.
