States, but are not obliged to do so--of right no new State can demand
admission into the Union, unless such demand be founded upon some
previous engagement of the United States.

When admitted by Congress into the Union, whether by compact or
otherwise, the new State becomes entitled to the enjoyment of the same
rights, and bound to perform the like duties as the other States;
and its citizens will be entitled to all privileges and immunities of
citizens in the several States.

The citizens of each State possess rights, and owe duties that are
peculiar to, and arise out of the Constitution and laws of the several
States. These rights and duties differ from each other in the different
States, and among these differences none is so remarkable or important
as that which proceeds from the Constitution and laws of the several
States respecting slavery; the same being permitted in some States and
forbidden in others.

The question respecting slavery in the old thirteen States had been
decided and settled before the adoption of the Constitution, which
