The University of Pennsylvania filed court papers refusing an EEOC subpoena that sought names and personal data of employees tied to Jewish faith or involvement in Jewish campus organizations, saying the request threatens constitutional and privacy rights. Penn said it has provided roughly 900 pages of materials but will not turn over lists that could identify employees without their consent, citing the history of governmental cataloging and safety concerns. The university asked a federal judge to deny the EEOC’s enforcement bid. The dispute follows broader federal probes into campus climates and anti‑Semitism; similar record demands have provoked backlash and litigation at other institutions. Penn’s filing frames the EEOC request as overbroad and not tied to specific allegations, setting up a legal test about how far investigative subpoenas may reach into personnel rosters and anonymous complaint processes. For campus leaders, the case raises tradeoffs between cooperating with civil‑rights investigations and protecting employee confidentiality and safety.
