Introduction
Kitzmiller v. Dover Area School District is a landmark case in American constitutional and educational law. Decided on December 20, 2005, by the United States District Court for the Middle District of Pennsylvania, the case was the first to directly address whether teaching intelligent design in public school science classes violates the Establishment Clause of the First Amendment. The ruling, delivered by Judge John E. Jones III, has had a profound and lasting impact on the intersection of science, religion, and education in the United States.
This guide provides an in-depth analysis of the case, its background, legal arguments, the court’s findings, and its broader implications. Attorneys, educators, and anyone interested in constitutional law or educational policy will benefit from understanding the nuances of this pivotal decision.
Background of the Case
The Dover Policy
In October 2004, the Dover Area School District in Pennsylvania adopted a policy requiring that students in ninth-grade biology classes be read a statement suggesting that there are gaps in Darwin’s theory of evolution and introducing intelligent design as an alternative explanation for the origin of life. The policy also directed students to a textbook, "Of Pandas and People," which advocates for intelligent design.
This policy marked the first time a public school district in the United States formally required the teaching of intelligent design alongside evolution. The school board’s stated intention was to encourage critical thinking and present alternative scientific theories. However, many community members and teachers saw the policy as a covert attempt to introduce religious doctrine into the science curriculum.
The Lawsuit
On December 14, 2004, eleven parents, represented by the American Civil Liberties Union of Pennsylvania (ACLU-PA), Americans United for Separation of Church and State, and the law firm Pepper Hamilton LLP, filed suit against the Dover Area School District. The plaintiffs argued that the policy violated the Establishment Clause of the First Amendment, which prohibits government endorsement or promotion of religion in public schools. ACLU Pennsylvania
The case was assigned to Judge John E. Jones III of the United States District Court for the Middle District of Pennsylvania. The trial began on September 26, 2005, and lasted for six weeks, featuring testimony from scientists, educators, theologians, and school board members.
Legal Issues and Arguments
The Establishment Clause
The central legal issue in Kitzmiller v. Dover was whether the school district’s policy violated the Establishment Clause of the First Amendment to the United States Constitution. The Establishment Clause prohibits any law "respecting an establishment of religion." In the context of public education, the Supreme Court has consistently held that public schools may not endorse or promote religious views. First Amendment Encyclopedia
Plaintiffs’ Arguments
The plaintiffs contended that intelligent design is not a scientific theory but a religious view, specifically a form of creationism. They argued that the Dover policy was a thinly veiled attempt to introduce religious doctrine into the science curriculum, in direct contravention of Supreme Court precedents such as Edwards v. Aguillard (1987), which struck down a Louisiana law requiring the teaching of creationism alongside evolution.
The plaintiffs presented evidence that:
- Intelligent design lacks empirical support and is not accepted by the scientific community as a valid scientific theory.
- The origins of intelligent design trace directly to creationist movements, particularly following the Supreme Court’s rejection of creationism in Edwards v. Aguillard.
- The school board’s motivations were religious, as evidenced by statements and actions of board members advocating for the teaching of creationism.
Defendants’ Arguments
The Dover Area School District defended the policy by asserting that intelligent design is a legitimate scientific theory and that mentioning it in the classroom promotes critical thinking. The defense denied any religious motivation, arguing that the policy was about academic freedom and exposing students to different scientific perspectives.
The defense also claimed that the policy did not require the teaching of intelligent design, but merely informed students of its existence, and therefore did not amount to government endorsement of religion.
The Trial
Testimony and Evidence
The trial featured extensive testimony from expert witnesses on both sides. The plaintiffs called scientists, philosophers of science, and educators who explained the nature of science, the scientific status of evolution, and the religious roots of intelligent design. The defense called proponents of intelligent design, including Michael Behe, a biochemist and prominent advocate for the concept.
Key points of testimony included:
- Scientific Status of Intelligent Design: Plaintiffs’ experts testified that intelligent design is not science because it invokes supernatural causation, lacks testable hypotheses, and is not supported by peer-reviewed research.
- Origins of Intelligent Design: Documentary evidence, including drafts of "Of Pandas and People," showed that the term "creationism" was replaced with "intelligent design" following the Edwards v. Aguillard decision, suggesting an attempt to rebrand creationism to circumvent legal restrictions.
- School Board Motives: Testimony revealed that some school board members made overtly religious statements, such as advocating for the teaching of "creationism" or referencing the Bible.
The Lemon Test
Judge Jones applied the Lemon test, established in Lemon v. Kurtzman (1971), to determine whether the policy had a secular purpose, whether its primary effect advanced or inhibited religion, and whether it fostered excessive government entanglement with religion. Justia
The Court’s Decision
Findings of Fact
In a comprehensive 139-page opinion, Judge Jones found in favor of the plaintiffs on every major point. The court concluded that intelligent design is not science, but a religious view that cannot be separated from its creationist roots. Key findings included:
- Intelligent Design is Not Science: The court found that intelligent design is not supported by peer-reviewed research, has not been accepted by the scientific community, and cannot be tested or falsified.
- Religious Motivation: The court determined that the Dover policy was motivated by religious beliefs, not by a genuine effort to improve science education.
- Violation of the Establishment Clause: The policy failed all three prongs of the Lemon test: it lacked a secular purpose, its primary effect was to advance religion, and it entangled the government with religious doctrine.
Legal Conclusions
Judge Jones ruled that the Dover Area School District’s policy was unconstitutional and permanently enjoined the district from requiring or permitting the teaching of intelligent design as an alternative to evolution in public school science classes. DocumentCloud
The decision was widely praised for its thoroughness and clarity. Judge Jones anticipated criticism by noting that the Founding Fathers themselves recognized the importance of separating church and state, and that protecting this principle was not an act of judicial activism but a fulfillment of constitutional duty.
Impact and Significance
National and Legal Impact
Kitzmiller v. Dover has had a profound impact on science education and the law. Although the decision is not binding precedent outside the Middle District of Pennsylvania, it has been highly influential in discouraging other school districts from adopting similar policies. No subsequent federal court has ruled in favor of teaching intelligent design in public schools.
The case reinforced the Supreme Court’s earlier decisions in Epperson v. Arkansas (1968) and Edwards v. Aguillard (1987), which struck down bans on teaching evolution and requirements to teach creationism, respectively. Kitzmiller extended these principles to intelligent design, making clear that any attempt to introduce religious concepts into science curricula would face constitutional challenges.
Educational Policy
The decision had immediate practical effects: the Dover Area School District was ordered to remove references to intelligent design from its curriculum, and the board members who supported the policy were voted out of office in the next election.
Nationally, the case served as a warning to other districts considering similar policies. Textbooks and curricula were revised to ensure compliance with constitutional requirements. Professional organizations, such as the National Center for Science Education, cited the case as a critical victory for science education. National Center for Science Education
Public Discourse and Media
Kitzmiller v. Dover received extensive media coverage, including features on PBS’s "NOVA" program, which produced a documentary titled "Judgment Day: Intelligent Design on Trial." The case became a touchstone in debates over the role of religion in public life and the boundaries of church and state. PBS
Legal scholars and commentators have lauded the decision for its detailed analysis and its defense of both scientific integrity and constitutional principles. The ruling continues to be cited in discussions about educational policy and the First Amendment.
Broader Legal and Societal Implications
The Nature of Science and Religion in Public Schools
Kitzmiller v. Dover clarified the legal boundaries between science and religion in the classroom. The decision affirmed that public school science curricula must be based on scientific evidence and methodologies, not religious doctrine. This distinction is crucial for maintaining both academic integrity and constitutional protections.
The court’s analysis of what constitutes science—emphasizing testability, peer review, and acceptance by the scientific community—provides a framework for evaluating future attempts to introduce non-scientific ideas into the curriculum.
The Establishment Clause in Practice
The case is a significant example of how the Establishment Clause operates in practice. It demonstrates that courts will look beyond the stated intentions of policymakers to examine the actual purpose and effect of government actions. The decision also underscores the importance of maintaining a secular public education system, free from religious endorsement or coercion.
Deterrence Effect
Since the Kitzmiller decision, there have been no successful efforts to introduce intelligent design or similar religious concepts into public school science classes. The case serves as a powerful deterrent, signaling that such policies will not withstand constitutional scrutiny. Science | AAAS
Frequently Asked Questions
Was Kitzmiller v. Dover appealed?
No, the Dover Area School District chose not to appeal the decision. The newly elected school board, which replaced the members who had supported the intelligent design policy, decided to accept the ruling and comply with the court’s order.
Does the decision apply outside Pennsylvania?
While the ruling is only directly binding within the Middle District of Pennsylvania, it has been highly persuasive elsewhere. Courts and policymakers across the United States have cited Kitzmiller as a guide for interpreting the Establishment Clause in the context of education.
What is the difference between intelligent design and creationism?
The court found that intelligent design is essentially a rebranded form of creationism. Both posit a supernatural designer, but intelligent design avoids explicit references to the Bible or specific religious doctrines. However, the court concluded that the underlying motivations and content are religious, not scientific.
