A federal judge ordered the University of Pennsylvania to provide the U.S. Equal Employment Opportunity Commission with lists that include employees affiliated with Jewish groups, advancing the EEOC’s investigation into allegations of harassment of Jewish employees. Penn argued the subpoena was overly broad, while the court said the request could be narrowly tailored. The decision includes exceptions that would prevent Penn from disclosing employees’ ties to specific Jewish-related organizations and limits disclosure for particular campus centers. Still, the ruling requires compliance by the court’s stated deadline and would compel significant administrative and legal coordination. Higher education leaders and civil-rights groups are likely to treat the case as a precedent for how federal agencies can request religious-affiliation-adjacent employment data in campus investigations.
