The law of the United States comprises many levels of codified and uncodified forms of law, of which the most important is the nation’s Constitution, which prescribes the foundation of the federal government of the United States, as well as various civil liberties.
The Constitution sets out the boundaries of federal law, which consists of Acts of Congress, treaties ratified by the Senate, regulations promulgated by the executive branch, and case law originating from the federal judiciary.
