Introduction
Few issues in recent memory have caused as much controversy as the banning of books. All over the country, school boards have taken up the task of reconsidering hundreds of books that deal with race, class, American history, sex, gender, politics, and religion. Advocates argue that parents and elected boards should decide what is suitable for children, while opponents argue that banning books based on their message violates a fundamental First Amendment right.
While both supporters and opponents of the bans focus on the local school board level, the issue has national constitutional implications. Does the First Amendment protect a student’s right to read? And if so, is a school board’s decision to remove books from libraries a First Amendment issue? As courts weigh in on these questions, book bans have become one of the most important issues in First Amendment law.
The Constitution and Book Bans
The First Amendment prohibits the government from restricting speech, but the Constitution says less about the right to receive information and ideas. Public schools present a unique constitutional challenge. Students do not have the same First Amendment rights as adults, but the Supreme Court has consistently ruled that the freedoms still apply inside the classroom. Moreover, school boards are government entities, so their decisions regarding library books are subject to constitutional oversight. At the same time, school boards have a great deal of autonomy when it comes to setting curriculums and managing school finances. The difficulty lies in distinguishing between permissible and impermissible reasons for banning books.
The Supreme Court first had to rule on the constitutionality of book bans in Board of Education v. Pico (1982). The case concerned a New York school board that wanted to remove several books from school libraries. The board argued that the books contained “vulgar” language and dealt with “socially offensive” topics. A plurality opinion from Justice Brennan held that while school boards have the right to make decisions about the curriculum, they cannot ban books simply because they disagree with the ideas they express. “Libraries are not places where school officials should feel most confident in suppressing dissent,” wrote Justice Brennan.
Justice Brennan further ruled that the First Amendment gives students a right to seek out books in libraries “in order to discover and explore diverse ideas and opinions,” so books dealing with controversial topics must be allowed to stay in schools. In practice, that means schools can ban books for being inappropriate or inaccurate, but removing books based on disagreements with their message violates the First Amendment. While Pico was a plurality opinion, later courts have struggled to interpret it and apply it to modern book bans.
Two Sides of the Same Coin
The book ban debates are not simply about books. They concern the proper role of a federal vs. a state government and the limits of free speech in public education. Proponents of school board-led book bans argue that elected officials have a responsibility to choose materials that are age-appropriate and not potentially offensive. They point to the Constitution and argue that the First Amendment allows them to ban books if they want to reduce classroom disruptions. School boards also believe that they know better than federal judges when it comes to deciding what materials to use in schools. They argue that budgetary and administrative decisions are always made with the best interests of students in mind and that book bans are no different.
Meanwhile, opponents maintain that schools should not ban books that express potentially controversial viewpoints. They argue that libraries exist to help students expand their knowledge and expose themselves to new ideas, so books in libraries should be allowed to occupy a space between classroom instruction and unrestricted free speech. The opponents of book bans believe that the First Amendment gives school students the right to read what they want. Thus, banning books based on potentially controversial themes is a First Amendment violation. Both sides raise valid arguments. In effect, the controversy centers on the following question: Does the First Amendment allow government officials to suppress any speech they find objectionable?
Why It Matters
While the book bans themselves are often local, the issues they raise cut across the entire Constitution. The book ban controversy is yet another reminder that while the government can place reasonable restrictions on when, where, and how people can express their ideas, it cannot suppress speech based on content. In effect, the bans have created a circuit court-level disagreement about the extent to which schools can regulate students’ speech in the classroom. In addition to exploring the limits of free speech, courts have to consider the balance between the federal and state governments and the rights of students.
The book ban controversy also shows just how far the long-standing First Amendment principles can be extended. Past court rulings on the First Amendment dealt primarily with traditional media like newspapers. In recent years, however, the Court has had to rule on multiple cases concerning the internet and the limits of free speech in the digital age.
Conclusion
Book bans may seem like just another school controversy, but they raise complex constitutional issues.The issue of book bans in public schools is complicated by the fact that school officials have both broad autonomy and notable restrictions when it comes to regulating students’ free speech. When book bans lead to First Amendment violations, it is often unclear where the responsibility lies. Nevertheless, as long as schools continue to ban books, courts will have to continue to rule on whether such bans violate the First Amendment. One of the most interesting questions in this debate is whether the First Amendment protects not only the right to speak but also the right to receive information.
