In City of Boerne v. Flores,'the United States Supreme Court held that through the enactment of the Religious Freedom Restoration Act ("RFRA) Congress exceeded its Fourteenth Amendment Enforcement Clause Power. The Court invalidated the statute because of its incongruence and its contradiction of vital principles necessary to maintain the Separation of Powers doctrine.
