The U.S. Class Action Fairness Act of 2005, 28 U.S.C. §§ 1332(d), 1453, 1711–15, expanded federal subject-matter jurisdiction over many large class action lawsuits and mass actions in the United States. The bill was the first major piece of legislation of the second term of the Bush Administration. Business groups and tort reform supporters had lobbied for the legislation, arguing that it was needed to prevent class action abuse. President George W. Bush had vowed to support this legislation.
