Which amendment is primarily associated with the case Tinker v. Des Moines?

The case of Tinker v. Des Moines School District, decided in 1969, is primarily associated with the First Amendment. This landmark decision established that students do not lose their constitutional rights to freedom of speech when they enter school grounds. In this case, the Tinker siblings wore black armbands to school to protest the Vietnam War, and the school attempted to prohibit this form of expression.

The Supreme Court ruled that the school's actions violated the students’ First Amendment rights, concluding that the wearing of armbands was a form of symbolic speech protected under the First Amendment. The decision underscored the importance of free expression in educational settings, affirming that such expression can be curtailed only if it causes a significant disruption to the educational process. This case has since become a fundamental reference point in discussions about student rights and free speech in schools.
