Opinion

On June 19, 1987 the Supreme Court, in a seven to two majority opinion written by Justice William J. Brennan, ruled that the Act constituted an unconstitutional infringement on the Establishment Clause of the First Amendment, based on the three-pronged Lemon test, which is:

1. The government's action must have a legitimate secular purpose;
2. The government's action must not have the primary effect of either advancing or inhibiting religion; and
3. The government's action must not result in an "excessive entanglement" of the government and religion.

However it did note that alternative scientific theories could be taught:

We do not imply that a legislature could never require that scientific critiques of prevailing scientific theories be taught. . . . Teaching a variety of scientific theories about the origins of humankind to schoolchildren might be validly done with the clear secular intent of enhancing the effectiveness of science instruction.

The Court found that, although the Louisiana legislature had stated that its purpose was to "protect academic freedom," that purpose was dubious because the Act gave Louisiana teachers no freedom they did not already possess and instead limited their ability to determine what scientific principles should be taught. Because it was unconvinced by the state's proffered secular purpose, the Court went on to find that the legislature had a "preeminent religious purpose in enacting this statute."
