Tinker v. Des Moines Independent Community School District, 393 U.S. 503 (1969)
(Students do not leave their rights at the schoolhouse door)
To protest the Vietnam War, Mary Beth Tinker and her brother wore black armbands to school. Fearing a disruption, the administration prohibited wearing such armbands. The Tinkers were removed from school when they failed to comply, but the Supreme Court ruled that their actions were protected by the First Amendment.
Goss v. Lopez, 419 U.S. 565 (1975)
(Students are entitled to certain due process rights)
Nine students at an Ohio public school received 10-day suspensions for disruptive behavior without due process protections. The Supreme Court ruled for the students, saying that once the state provides an education for all of its citizens, it cannot deprive them of it without ensuring due process protections.
