As part of its efforts to hold Wells Fargo civilly liable for alleged discriminatory lending practices, Philadelphia is demanding that the lending giant turn over its internal and compliance audits.

The city on Thursday filed a motion with the U.S. District Court for the Eastern District of Pennsylvania asking to have the court compel all audits and audit-related documents related to the company’s compliance with the federal Fair Housing Act when it comes to underwriting, purchasing, pricing or selling loans to minority residents of Philadelphia.
