Tinker v. Des Moines Independent Community School District case was influenced by the dissent of the Supreme Court decision that the students had the right to wear the armbands to school likely because (B) Students at the school were allowed to wear other controversial symbols by First Amendment.
An important Supreme Court decision from 1969 called Tinker v. Des Moines established students' freedom of speech rights in public schools. According to the court, the First Amendment applied to public schools, and administrators could not suppress student expression unless it interfered with the learning environment. The court determined that students' right to wear black armbands was protected by the First Amendment because doing so was not disruptive.
