Creates the Civil Liberties Defense Act, which provides that certain rulings shall be unenforceable if based on certain foreign laws

SB 1456 would prevent courts from enforcing legal decisions that rely on specific foreign laws. This directly affects state courts and legal cases where foreign legal standards are applied in rulings. The bill creates a mechanism to block enforcement of such decisions, though it does not specify which foreign laws or types of rulings are covered. As a procedural bill, it focuses on establishing this restriction rather than changing substantive law.
