Federal Criminal

Federal Government
or federalism, form of government whereby
political power is divided between a central
or national authority and smaller, locally
autonomous units such as provinces or states,
generally under the terms of a constitution.
A federal government, or federation, is usually
formed through the political union of two or
more formerly independent states under one
sovereign government that does not, in any
case, arrogate the individual powers of those
states.

In the United States, criminal law has a number
of unique features. In many particulars it varies
from state to state, for example. Underlying most
of the divergences is an identity of standpoint and
tradition derived from English common law, which
is the origin of nearly all US law. Criminal law also
classifies a crime with respect to its gravity, such
as treason, felony, and misdemeanour
