In Fratello v. Roman Catholic Archdiocese of New York, (SD NY, March 29, 2016), a New York federal district court held that the “ministerial exception” to Title VII of the 1964 Civil Rights Act precludes the former lay principal of a Catholic elementary school from suing for employment discrimination. Plaintiff alleged that her employment was terminated as a result of gender discrimination and retaliation. In relying on the ministerial exception doctrine as set out in the U.S. Supreme Court’s 2012 Hosanna-Tabor decision, the district court said in part:
There is no dispute that Plaintiff is not a member of the clergy and that she would not be considered a minister for purposes of Church governance. But the issue here is one of U.S., not canon, law, and “minister” for purposes of the ministerial exception has a far broader meaning than it does for internal Church purposes.
