The state of Aurora is determined to regulate paralegals. A group of paralegals is lobbying hard for regulation so that the paralegals can be distinguished from nonlawyer legal service providers who often use the title "paralegal." Two years earlier, the Aurora Supreme Court struck down legislation that would have allowed nonlawyers to represent clients in workers' compensation cases. The proposed legislation regulating paralegals is passed and signed into law. A group of lawyers files suit, requesting that the court declare the legislation invalid. Under what theory might the court strike down the legislation? Would the same result be likely in all jurisdictions? If the legislation is found unconstitutional and is struck down, what should the paralegals do to get the regulation they want?
