Lemon test. A legal standard for judging the state’s violation of the Establishment Clause of the First Amendment. • The Lemon test has most often been used in school-related cases. It employs a three-pronged test to determine the state’s action: (1) Does the state’s action have a religious purpose? (2) Does the state’s action have the primary effect of either promoting or inhibiting religion? (3) Does the state’s action create an “excessive entanglement” between church and state? Lemon v. Kurtzman, 403 U.S. 602, 91 S.Ct. 2105 (1971). In recent years, the Court has not overturned Lemon but has declined to apply it when deciding Establishment Clause cases.
