Smith Thompson,
Groves v. Slaughter — Opinion of the Court
“ That prohibits only the introduction of slaves into the state, by the citizens of other states, as merchandize; but the constitution of Ohio not only does this, but it declares that slavery shall not exist in the state. Does not the greater power include the lesser? If Ohio may prohibit the introduction of slaves into it altogether, may not the state of Mississippi regulate their admission? The constitution of the United States operates alike on all the states; and one state has the same power over the subject of slavery as every other state. ”
