In which United States Supreme Court case concerning the constitutionality of teaching creationism stated that Creationism is an inherently religious concept and that advocating it as correct or accurate in public-school curricula violates the Establishment Clause of the First Amendment
Edwards v. Aguillard Edwards v. Aguillard, 482 U.S. 578 (1987), was a United States Supreme Court case concerning the constitutionality of teaching creationism. The Court ruled that a Louisiana law requiring that where evolutionary science was taught in public schools, creation science must also be taught, violated the Establishment Clause of the First Amendment because the law was specifically intended to advance a particular religion. It also held that "teaching a variety of scientific theories about the origins of humankind to school children might be validly done with the clear secular intent of enhancing the effectiveness of science instruction".
McGowan v. Maryland McGowan v. Maryland, 366 U.S. 420 (1961), was a United States Supreme Court case in which the court held that laws with religious origins are not unconstitutional if they have secular purpose.
