A consumer protection lawyer can assist consumers in many different areas of consumer law. Some lawyers who specialize in consumer protection focus their practices exclusively on cases involving pharmaceuticals, or medical products and devices. Other lawyers maintain a more broad-based consumer protection practice, concentrating on any type of case in which consumers' rights have been violated, such as those cases involving the Fair Debt Collection Practices Act, state lemon laws related to the purchase of vehicles, credit card regulations, and "Do Not Call" telemarketing laws. While consumers can file complaints about violations of consumer laws with the appropriate federal government agencies, such as the U.S. Consumer Product Safety Commission and the Federal Trade Commission's Bureau of Consumer Protection, only a consumer protection lawyer can provide assistance to an individual consumer who has been injured or harmed by a product or some other violation of federal and/or state consumer protection laws.
