MR. JUSTICE FORTAS delivered the opinion of the Court.
This appeal challenges the constitutionality of the "anti-evolution" statute which the State of Arkansas adopted in 1928 to prohibit the teaching in its public schools and universities of the theory that man evolved from other species of life. The statute was a product of the upsurge of "fundamentalist" religious fervor of the twenties. The Arkansas statute was an adaptation of the famous Tennessee "monkey law" which that State adopted in 1925. The constitutionality of the Tennessee law was upheld by the Tennessee Supreme Court in the celebrated Scopes case in 1927.
The Arkansas law makes it unlawful for a teacher in any state-supported school or university "to teach the theory or doctrine that mankind ascended or descended from a lower order of animals," or "to adopt or use in any such institution a textbook that teaches" this theory. Violation is a misdemeanor and subjects the violator to dismissal from his position.
The present case concerns the teaching of biology in a high school in Little Rock. According to the testimony, until the events here in litigation, the official textbook furnished for the high school biology course did not have a section on the Darwinian Theory. Then, for the academic year 1965-1966, the school administration, on recommendation of the teachers of biology in the school system, adopted and prescribed a textbook which contained a chapter setting forth "the theory about the origin . . . of man from a lower form of animal."
Susan Epperson, a young woman who graduated from Arkansas' school system and then obtained her master's degree in zoology at the University of Illinois, was employed by the Little Rock school system in the fall of 1964 to teach 10th grade biology at Central High School. At the start of the next academic year, 1965, she was confronted by the new textbook (which one surmises from the record was not unwelcome to her). She faced at least a literal dilemma because she was supposed to use the new textbook for classroom instruction and presumably to teach the statutorily condemned chapter; but to do so would be a criminal offense and subject her to dismissal.
She instituted the present action in the Chancery Court of the State, seeking a declaration that the Arkansas statute is void and enjoining the State and the defendant officials of the Little Rock school system from dismissing her for violation of the statute's provisions....
Arkansas' law cannot be defended as an act of religious neutrality. Arkansas did not seek to excise from the curricula of its schools and universities all discussion of the origin of man. The law's effort was confined to an attempt to blot out a particular theory because of its supposed conflict with the Biblical account, literally read. Plainly, the law is contrary to the mandate of the First, and in violation of the Fourteenth, Amendment to the Constitution....
MR. JUSTICE BLACK, concurring.
I am by no means sure that this case presents a genuinely justiciable case or controversy. Although Arkansas Initiated Act No. 1, the statute alleged to be unconstitutional, was passed by the voters of Arkansas in 1928, we are informed that there has never been even a single attempt by the State to enforce it. And the pallid, unenthusiastic, even apologetic defense of the Act presented by the State in this Court indicates that the State would make no attempt to enforce the law should it remain on the books for the next century. Now, nearly 40 years after the law has slumbered on the books as though dead, a teacher alleging fear that the State might arouse from its lethargy and try to punish her has asked for a declaratory judgment holding the law unconstitutional. She was subsequently joined by a parent who alleged his interest in seeing that his two then school-age sons "be informed of all scientific theories and hypotheses . . . ." But whether this Arkansas teacher is still a teacher, fearful of punishment under the Act, we do not know. It may be, as has been published in the daily press, that she has long since given up her job as a teacher and moved to a distant city, thereby escaping the dangers she had imagined might befall her under this lifeless Arkansas Act. And there is not one iota of concrete evidence to show that the parent-intervenor's sons have not been or will not be taught about evolution. The textbook adopted for use in biology classes in Little Rock includes an entire chapter dealing with evolution. There is no evidence that this chapter is not being freely taught in the schools that use the text-book and no evidence that the intervenor's sons, who were 15 and 17 years old when this suit was brought three years ago, are still in high school or yet to take biology. Unfortunately, however, the State's languid interest in the case has not prompted it to keep this Court informed concerning facts that might easily justify dismissal of this alleged lawsuit as moot or as lacking the qualities of a genuine case or controversy.
Notwithstanding my own doubts as to whether the case presents a justiciable controversy, the Court brushes aside these doubts and leaps headlong into the middle of the very broad problems involved in federal intrusion into state powers to decide what subjects and school-books it may wish to use in teaching state pupils....
