In what the court referred to as a “case of first impression,” a district court in Pennsylvania held a state agency’s investigation of a discrimination complaint filed with HUD based on a federal saving bank’s rejection of a loan application was not preempted by Office of Thrift Supervision regulations or an impermissible exercise of visitorial powers. USAA Fed. Savings Bank v. Pennsylvania Human Relations Commission, 2011 U.S. Dist. LEXIS 94982 (E.D. Pa. Aug. 23, 2011). The court reasoned that the Fair Housing Act expressly authorizes HUD to delegate investigative authority in state agencies, so the investigation was an exercise of federal authority and not preempted by federal law.
