Does the salazar v buono case use the lemon test?

Yes, the Salazar v. Buono case involved the Lemon test, which is used to determine whether a government action violates the Establishment Clause of the First Amendment. The Supreme Court's decision addressed whether a cross on federal land constituted an endorsement of religion. The case ultimately focused on issues of standing and the interpretation of governmental endorsement rather than a straightforward application of the Lemon test, but the test's principles were relevant to the arguments presented.
