PA HB403

Prohibits Pennsylvania municipalities from adopting "sanctuary" policies that limit cooperation between local law enforcement, corrections officers, parole officers, or judicial staff and federal immigration authorities including ICE and USCIS.

Requires law enforcement agencies and municipalities to comply with federal immigration detainer requests, hold individuals subject to detainers, and share information about inmates' release dates, immigration status, names, and birthdates with federal agencies.

Allows individuals adversely affected by prohibited sanctuary policies—including municipal residents and police officers—to file lawsuits seeking declaratory or injunctive relief in Commonwealth Court.

Imposes liquidated damages of $100,000 per day a prohibited policy remains in effect, or $1,000,000 minimum, with funds deposited into a newly established Immigration Cooperation Fund administered by the Pennsylvania Commission on Crime and Delinquency to provide grants for immigration enforcement cooperation.

Requires the Attorney General to defend law enforcement agencies and municipalities sued for good faith compliance with the cooperation requirements, with the Commonwealth covering all legal costs, judgments, and settlements; effective date January 1, 2026.
