In Committee for Public Education v. Nyquist, the U.S. Supreme Court invalidates a New York law that gives facility-maintenance grants to non-public schools with a high concentration of low-income students, as well as tuition reimbursement and tax credits to low-income students at such schools. The Court finds that the law has the “primary effect” of promoting religion, and that it entangles government and religion by helping religious schools stay in business and encouraging parents to send their children to them.
