PHILADELPHIA — University of Pennsylvania law professor Amy Wax, who was sanctioned in September for what Penn called “years of flagrantly unprofessional conduct,” sued the school, alleging in the federal complaint that its speech policies are “racially discriminatory” and “violate core principles of the First Amendment.

Law-school professor at the University of Pennsylvania sues her Ivy League employer over her suspension in September, arguing the school’s speech policy is racially discriminatory and violated her First Amendment rights.

A White Jewish professor has sued the University of Pennsylvania for breach of contract, accusing the institution of “racist double standards” for suspending her over race-related comments while allowing other employees to smear Jews without consequence.

The university sanctioned Wax in September following a long history of controversial speech, including derogatory comments about Asian immigrants and claims Black students underperform academically.
