Penn Carey Law School professor Amy Wax sued the University of Pennsylvania and its Board of Trustees in Pennsylvania federal court Thursday over the school’s speech policy and the sanctions passed against her regarding her comments on Black students’ performance at the law school, Asian immigrants, and her invitations to white nationalist Jared Taylor to speak at her classes.

This lawsuit, filed in the U.S. District Court for the Eastern District of Pennsylvania by attorneys from Holtzman Vogel, claims that the rationale behind the sanctions, namely Wax’s comments regarding Black students’ academic performance, “is demonstrably pretextual and served as a thin veneer for the University’s true rationale: under its speech policies … some races may not be criticized while other racial or ethnic groups can be—and routinely are—subjected to virulently racist speech without consequence.”
