The year 1988 is significant in the context of the First Amendment as it marks the establishment of the legal precedent in the landmark Supreme Court case 'Hazelwood School District v. Kuhlmeier'. This case addressed the extent of student free speech rights within public schools, specifically examining the balance between school authority and students' rights to expression. The ruling underscored the limitations on First Amendment protections in educational settings, influencing how schools can regulate student speech and publications.
