The doctrine determines whether thousands of employees at religious schools, hospitals and charities can sue over discrimination based on race, sex, age or disability.
Religious groups generally can't be sued for discrimination by workers whose jobs involve spreading or teaching the faith.
It marks a line between government enforcement of civil rights laws and religious groups' autonomy to choose who carries out their mission.
Federal courts derive the exception from the First Amendment's Religion Clauses, not from a specific statute, and apply it to bar covered claims at the outset of a lawsuit.
Judges look at the employee's actual duties — such as teaching religion, leading prayer or conveying the faith — rather than relying solely on a job title like 'minister.'
Federal law bars most workplace discrimination, but carves out space for faith-based employers — and courts have been defining how much.
