Public and Private Laws - GovInfoPublic and private laws are also known as slip laws. A slip law is an official publication of the law and is competent evidence admissible in all state and Federal courts and tribunals of the United States. After the President signs a bill into law, it is delivered to the Office of the Federal Register (OFR), National Archives and Records Administration (NARA) where it is assigned a law number, legal statutory citation (public laws only), and prepared for publication as a slip law. Private laws receive their legal statutory citations when they are published in the United States Statutes at Large. Prior to publication as a slip law, OFR also prepares marginal notes and citations for each law, and a legislative history for public laws only. Until the slip law is published, through the U.S. Government Publishing Office (GPO), the text of the law can be found by accessing the enrolled version of the bill
