“The ultimate arbiter is the people of the Union, assembled by their deputies in convention, at the call of Congress, or of two-thirds of the States. Let them decide to which they mean to give an authority claimed by two of their organs. And it has been the peculiar wisdom and felicity of our constitution, to have provided this peaceable appeal, where that of other nations is at once to force.” Thomas Jefferson Letter to William Johnson, June 12th, 1823
