I want to know the answer to the following question:
What did the state's policy violate?
All the background I'm provided with is that "In Lemon v. Kurtzman, 403 U.S. 602 (1971), the court determined that a Pennsylvania state policy of reimbursing the salaries and related costs of teachers of secular subjects in private religious schools violated the Establishment Clause.". Is that enough to answer the question?
