May states be required to grant exemptions for business owners whose Sabbath requires them to close their business on another day?
No. In Braunfeld v. Brown (1961) the Supreme Court held that observance of a Sabbath was an individual’s choice, and that a person was not discriminated against or disadvantaged by the state for its decision to require the closing of businesses on a day other than that individual’s Sabbath. States may choose to allow exemptions for certain individuals, but they may not be required to do so.
