Federal law

Federal law is the body of law created by the federal government of a
nation. Examples of federal governments include the United States of
America, Canada, the former Union of Soviet Socialist Republics, India, and
the European Union.

The United States Constitution provides for a federal government that is
superior to state governments with regard to its enumerated powers. These
powers include the authority to govern international affairs, the currency,
and national defense. After the Civil War, the Fourteenth Amendment applied
the Bill of Rights to state governments. Issues that arise under any
legislation passed by Congress, an Executive Order of the President or a
decision of federal courts persuant to the United States Constitution are
governed by federal law.

The Supreme Court of the United States has the sole authority to interpret
the Constitution and makes final decisions regarding all federal laws.
Congress has created inferior courts.
