How did the Tinker v Des Moines case expand rights of minors?

The landmark case of Tinker v. Des Moines Independent Community School District (1969) expanded the rights of minors by establishing the First Amendment rights of students in public schools. The case centered around a group of students who were suspended for wearing black armbands to protest the Vietnam War. The Supreme Court ruled in favor of the students, recognizing their right to express their opinions and participate in peaceful protests while at school. This ruling set an important precedent for protecting the freedom of speech and expression of students, ensuring that their rights are not limited solely because they are minors.
