The purpose of this legislation, known as the Protecting American Consumers from Robocalls Act, is to enhance protections for consumers against unwanted telemarketing calls, particularly those made by automated systems. The main objectives are to broaden the existing Do Not Call rules to cover all telephone subscribers, not just residential ones, and to strengthen the legal rights of individuals to take action against violations of these rules. Key provisions of the legislation include significant changes to the Do Not Call rules under the Telephone Consumer Protection Act.
