Practice Question: Darian owns a payday and title loan agency. He makes loans to individuals secured by a lien on the borrowers paychecks or vehicle title. He recently expanded his operations to include making unsecured student and training loans in exchange for a percentage of future wages post graduation. His operations are generally regulated by the Consumer Financial Protection Bureau (CFPB). The agency investigates Darians new business practice and seeks to levy on fine on his business for failing to make the required consumer disclosures. What are Darians options for challenging the authority of the CFPB to regulate his business activity?
