The purpose of this legislation, known as the "End PG&E Lobbying Act," is to create a federal rule that imposes a two-year ban on lobbying activities for individuals who have recently served on state regulatory authorities. This aims to prevent former members from influencing decisions or gaining insider information from the regulatory bodies they once were part of. Key provisions of the law include a clear prohibition on former members of state regulatory authorities from appearing before or lobbying their former agencies for two years after leaving their position.
