Super PACs, officially known as "independent expenditure-only political action committees," are unlike traditional PACs in that they may engage in unlimited political spending (on, for example, ads) independently of the campaigns, and may raise funds from individuals, corporations, unions, and other groups without any legal limit on donation size. However, they are not allowed to either coordinate with or contribute directly to candidate campaigns or party coffers. Super PACs are subject to the same organizational, reporting, and public disclosure requirements of traditional PACs.
Super PACs were made possible by two judicial decisions in 2010: the aforementioned Citizens United v. Federal Election Commission and, two months later, Speechnow.org v. FEC. In Speechnow.org, the federal Court of Appeals for the D.C. Circuit held that PACs that did not make contributions to candidates, parties, or other PACs could accept unlimited contributions from individuals, unions, and corporations (both for profit and not-for-profit) for the purpose of making independent expenditures.
