Federal law is the body of
law created by the
federal government of a country. A federal government is formed when a group of political units, such as
states or
provinces join together in a
federation, surrendering their individual
sovereignty and many powers to the
central government while retaining or reserving other limited powers. As a result, two or more levels of government exist within an established geographic territory. The body of law of the common central government is the federal law.
