The Free Lemon Test refers to a legal standard developed by the Supreme Court of the United States in the case of Lemon v. Kurtzman (1971) to determine the constitutionality of laws that potentially violate the First Amendment's Establishment Clause. The test has three prongs and requires that a law must have a secular purpose, its primary effect should neither advance nor inhibit religion, and it should not result in excessive entanglement between government and religion.
