In what year was the Lemon test established?

The Lemon test was established in the year 1971 as a result of the Supreme Court case Lemon v. Kurtzman. This case addressed the issue of whether state funding for private religious schools violated the Establishment Clause of the First Amendment. The Supreme Court ruled that government action concerning religion should be evaluated using a three-part test, which became known as the Lemon test. This test evaluates whether a law has a secular purpose, whether it advances or inhibits religion, and whether it fosters an excessive government entanglement with religion. Thus, the correct choice reflects the significant legal framework established at that time, which has since been used to assess many cases related to the separation of church and state.
