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?
Answer: yes
