A statute is the law as passed by the U.S. Congress, a State Legislature, or local government. At the local level statutes are often called ordinances. In most cases, statutory laws are published in 2 forms: a chronological form — exactly as passed by the legislature and a codified form in which the laws are arranged by topic and all superseded and repealed laws are removed.
Sources of statutory laws include:
The Executive Branch, federal departments and agencies, are charged with developing regulations to enforce statutes passed by congress. These regulations are referred to as regulatory or administrative law. Like statutes administrative regulations are published in a daily chronological version (the Federal Register) and in a codified version (Code of Federal Regulations).
