John Archibald Campbell, Marshall v. Baltimore and Ohio Railroad Company…
“ Resistance and retaliation would lead to conflict and confusion, and the weaker States must either submit to have their policy controlled, their business monopolized, their domestic institutions reduced to insignificance, or the peace and harmony of the States broken up and destroyed.' To this consummation this judgment of the court is deemed to be a progress. The word 'citizen,' in American constitutions, state and federal, had a clear, distinct, and recognized meaning, understood by the common sense, and interpreted accordingly by this court through a series of adjudications. ”
