A former Catholic school teacher who was fired for expressing her support of abortion rights in a newspaper ad that ran on the 30th anniversary of Roe v. Wade may not sue the school under Title VII because such a claim would force the courts to rule on the validity of a religious institution’s beliefs, the 3rd U.S. Circuit Court of Appeals has ruled.

In its 22-page opinion in Curay-Cramer v. The Ursuline Academy of Wilmington, the court rejected the plaintiff’s argument that Title VII’s “opposition clause” protects any employee who has had an abortion, who contemplates having an abortion or who supports the rights of women who do so.
