This document summarizes three important Supreme Court cases related to students' rights. In New Jersey v. T.L.O. (1985), the Court ruled 6-3 that a school principal's search of a student who was smoking in the bathroom was justified under the Fourth Amendment even without a warrant. In Regents of the U. of CA v. Bakke (1978), the Court ruled 5-4 that a university's affirmative action policy that rejected a white applicant in favor of minority students with lower GPAs violated civil rights law. Finally, in Tinker v. Des Moines (1969), the Court ruled 7-2 in favor of students who wore black armbands to school in protest of the Vietnam War
