in lemon v kurtzman the supreme court found that
Lemon v. Kurtzman Lemon v. Kurtzman, 403 U.S. 602 (1971),[1] was a case argued before the Supreme Court of the United States. The court ruled in an 8â€“1[2] decision that Pennsylvania's Nonpublic Elementary and Secondary Education Act (represented through David Kurtzman) from 1968 was unconstitutional, violating the Establishment Clause of the First Amendment. The act allowed the Superintendent of Public Schools to reimburse private schools (mostly Catholic) for the salaries of teachers who taught in these private schools, from public textbooks and with public instructional materials. The decision also upheld a decision of the First Circuit, which had struck down the Rhode Island Salary Supplement Act providing state funds to supplement salaries at private elementary schools by 15%. As in Pennsylvania, most of these funds were spent on Catholic schools.
