The ministerial exception, sometimes known as the "ecclesiastical exception," is a legal doctrine in the United States barring the application of anti-discrimination laws to religious institutions' employment relationships with its "ministers." As explained by the Supreme Court in the landmark case Hosanna-Tabor Evangelical Lutheran Church and School v. E.E.O.C., the exception is drawn from the First Amendment to the United States Constitution, and seeks to both (1) safeguard religious groups' "freedom. .. to select their own ministers," a principle rooted in the Free Exercise Clause, and (2) prevent "government involvement in [] ecclesiastical decisions," a prohibition stemming from the Establishment Clause. When applied, the exception operates to give religious institutions an affirmative defense when sued for discrimination by employees who qualify as "ministers;" for example, female priests cannot sue the Catholic church to force their hiring. However, exactly which types of employees should qualify as a "ministers," and thus how broadly the exception should apply, was the subject of recent litigation before the Supreme Court.
