The 'Lemon test' is a three-part standard established by the Supreme Court to determine whether a government action violates the Establishment Clause of the First Amendment, which prohibits the government from making any law 'respecting an establishment of religion.' To pass the test, a government action must satisfy three criteria: first, it must have a secular legislative purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion; and finally, it must not foster an excessive government entanglement with religion. The Lemon test aimed to provide a clear and objective framework for navigating the complex relationship between church and state. However, the test has been criticized by many judges and legal scholars for being subjective and difficult to apply consistently. Some argue that the test is too hostile to religion, while others contend that it is too permissive. As a result, the Court has increasingly moved away from the Lemon test in favor of other approaches, such as the 'endorsement test' or an emphasis on historical tradition.
