The law of the United States is made up of many levels of codified and uncodified forms of law. The most important these is the United States Constitution. This established the federal government of the United States. The Constitution sets out the boundaries of federal law. This consists of acts of Congress, treaties ratified by the Senate, regulations promoted by the executive branch, and case law originating from the federal judiciary. The United States Code is the official compilation and codification of general and permanent federal statutory law.
