Common questions
Frequently Asked
4
When does a law trigger strict scrutiny under the Free Exercise Clause?+
A law triggers strict scrutiny when it targets religious conduct or is not neutral and generally applicable. Discretionary exemption mechanisms that allow officials to grant individualized waivers also render a policy non-neutral. Strict scrutiny then requires the government to show a compelling interest pursued by the least restrictive means.

Does the Free Exercise Clause require exemptions from neutral generally applicable laws?+
Neutral generally applicable laws that incidentally burden religion do not require exemptions under the Free Exercise Clause. States may enforce such laws even when they conflict with religious practices absent evidence of targeting. Unemployment benefits may be denied when a dismissal stems from violation of a criminal prohibition applied evenly.
Supporting sources
May a state exclude religious schools from generally available funding programs?+
A state may not exclude religious schools from generally available funding programs solely because of their religious character. The Free Exercise Clause requires equal treatment of religious and nonreligious options in neutral aid programs. Exclusion violates neutrality even if the school integrates faith throughout its curriculum.
Supporting sources
How does compulsory school attendance interact with Free Exercise rights?+
Compulsory attendance laws must yield when they substantially burden parents whose religion forbids secondary education. An exemption is available where the community is law-abiding and self-sufficient and its alternative practices satisfy state interests. The clause combined with parental rights supports the exemption under these conditions.
