If a number of political societies enter into a larger political society, the laws which the latter may enact, pursuant to the powers intrusted to it by its constitution, must necessarily be supreme over those societies and the individuals of whom they are composed.... But it will not follow from this doctrine that acts of the larger society which are not pursuant to its constitutional powers, but which are invasions of the residuary authorities of the smaller societies, will become the supreme law of the land. These will be merely acts of usurpation, and will deserve to be treated as such.
