What describes the lemon test?

The Lemon Test is a legal precedent established by the Supreme Court of the United States in Lemon v. Kurtzman (1971). It provides a three-pronged test to determine the constitutionality of government actions that potentially infringe upon the Establishment Clause of the First Amendment of the United States Constitution, which prohibits the government from establishing a religion.

The three prongs of the Lemon Test are as follows:

1. The government action must have a secular (non-religious) purpose.
2. The primary effect of the government action should neither advance nor inhibit religion.
3. The government action should not result in excessive entanglement between government and religion.

If any of these prongs of the test are violated, the government action would be deemed unconstitutional. This test helps to evaluate whether a government policy or action violates the principle of separation of church and state.
