Did the Montana Supreme Court Violate the Constitution When It Struck a State Program That Offered Montanans Dollar-for-Dollar Tax Credits for Donations to Private Schools, Including Religious Schools, for the Purpose of Paying Student Tuition?

The plaintiffs argue first that the Montana Supreme Court's ruling violates the Free Exercise Clause, which prohibits the government from discriminating against religion. Finally, the plaintiffs argue that the Montana Supreme Court ruling violates the Establishment Clause, which prohibits both certain government support of religion and (as relevant here) government hostility toward religion. The Court previously held in Locke v. Davey, also mentioned above, that a state did not violate the Free Exercise Clause when it excluded from a state scholarship program students pursuing a degree in theology.
