Edwards v. Aguillard,
482 U.S. 578 (1987)
Louisiana's "Creationism Act" forbids the teaching of the theory of evolution in public elementary and secondary schools unless accompanied by instruction in the theory of "creation science." The Act does not require the teaching of either theory unless the other is taught. It defines the theories as "the scientific evidences for [creation or evolution] and inferences from those scientific evidences." Appellees, who include Louisiana parents, teachers, and religious leaders, challenged the Act's constitutionality in Federal District Court, seeking an injunction and declaratory relief. The District Court granted summary judgment to appellees, holding that the Act violated the Establishment Clause of the First Amendment. The Court of Appeals affirmed.
Held: The Act is facially invalid as violative of the Establishment Clause of the First Amendment, because it lacks a clear secular purpose.

POWELL, J., filed a concurring opinion, in which O'CONNOR, J., joined. WHITE, J., filed an opinion concurring in the judgment. SCALIA, J., filed a dissenting opinion, in which REHNQUIST, C. J., joined.
