Statutory law is comprised of statutes, laws established by the legislature and signed by the executive. A "statute" is interchangeable with a "law" or an "act." All laws start as bills, a proposal for new legislation, that must be discussed by the legislature. For federal statutory law, bills must be approved by both houses of Congress (the House of Representatives and the Senate) before being signed by the President of the United States to become a law. State statutory law operates in the same way with laws being passed by the state legislature and approved by the state governor. If a law is rejected by the executive, known as being vetoed, the bill returns to the legislature where it must reach a certain majority threshold vote to override the veto.
Statutes are officially published numerous times and in different organizational schemes. For the federal system, an individual statute will first be published on its own, known as a slip law (often published as individual sheets or slips of paper). For each session of Congress, all slip laws passed in that time will be published together as session laws. Those session laws are contained in the publication Statutes at Large and are organized in chronological order. Eventually, those session laws, if of a "general and permanent nature," will be compiled in the United States Code (U.S.C), where the laws are organized by topic. Each topic is represented by a "title" (Title 17 is Copyright, Title 49 is Transportation, etc.). State statutory schemes typically follow the same progression of slip law, statutes at large, and code integration.
