Question

Why does Tinker v. Des Moines remain an important precedent-setting case?

It solely protected speech rights in war protests.
It applied prior restraint in schools.
It established speech rights for students.
It stopped students from stating unpopular opinions

Answer 1

"It established speech rights for students."

Tinker held that students do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate," protecting student political speech so long as it does not materially and substantially disrupt school operations. The other choices are incorrect: it was not limited to war protests, it did not impose prior restraint, and it did not forbid unpopular opinions (it protected them).
