This document summarizes three landmark Supreme Court cases from the 1970s that involved challenges to the First and Fourteenth Amendments: Regents of the University of California v Bakke challenged affirmative action policies; Texas v Johnson protected flag burning as free speech; and Hazelwood v Kuhlmeier allowed censorship of a school newspaper for pedagogical reasons. Bakke ruled against racial quotas, Johnson ruled symbolic speech is protected, and Kuhlmeier gave school administrators control over school-sponsored publications. These cases helped define key constitutional rights and limitations.
