Mueller v. Allen,
463 U.S. 388 (1983)
A Minnesota statute (§ 290.09, subd. 22) allows state taxpayers, in computing their state income tax, to deduct expenses incurred in providing "tuition, textbooks and transportation" for their children attending an elementary or secondary school. Petitioner Minnesota taxpayers brought suit in Federal District Court against respondent Minnesota Commissioner of Revenue and respondent parents who had taken the tax deduction for expenses incurred in sending their children to parochial schools, claiming that § 290.09, subd. 22, violates the Establishment Clause of the First Amendment by providing financial assistance to sectarian institutions. The District Court granted summary judgment for respondents, holding that the statute is neutral on its face and in its application and does not have a primary effect of either advancing or inhibiting religion. The Court of Appeals affirmed.
Held: Section 290.09, subd. 22, does not violate the Establishment Clause, but satisfies all elements of the "three-part" test laid down in Lemon v. Kurtzman, 403 U.S. 602, that must be met for such a statute to be upheld under the Clause.
