There is fortunately no difficulty in solving the question. There are two provisions in the Constitution, under one of which the case must fall. The fourth article says:
"New States may be admitted by the Congress into this Union."
In my judgment this is the controlling provision in this case. Unless the law of nations is a dead letter, the late war between two acknowledged belligerents severed their original compacts, and broke all the ties that bound them together. The future condition of the conquered power depends on the will of the conqueror. They must come in as new States or remain as conquered provinces. Congress—the Senate and House of Representatives, with the concurrence of the President—is the only power that can act in the matter. But suppose, as some dreaming theorists imagine, that these States have never been out of the Union, but have only destroyed their State governments so as to be incapable of political action; then the fourth section of the fourth article applies, which says:
"The United States shall guarantee to every State in this Union a republican form of government."
Who is the United States? Not the judiciary; not the President; but the sovereign power of the people, exercised through their representatives in Congress, with the concurrence of the Executive. It means the political Government—the concurrent action of both branches of Congress and the Executive. The separate action of each amounts to nothing, either in admitting new States or guaranteeing republican governments to lapsed or outlawed States. Whence springs the preposterous idea that either the President, or the Senate, or the House of Representatives, acting separately, can determine the right of States to send members or Senators to the Congress of the Union?
To prove that they are and for four years have been out of the Union for all legal purposes, and, being now conquered, subject to the absolute disposal of Congress, I will suggest a few ideas and adduce a few authorities. If the so-called "confederate States of America" were an independent belligerent, and were so acknowledged by the United States and by Europe, or had assumed and maintained an attitude which entitled them to be considered and treated as a belligerent, then, during such time, they were precisely in the condition of a foreign nation with whom we were at war; nor need their independence as a nation be acknowledged by us to produce that effect.
After such clear and repeated decisions it is something worse than ridiculous to hear men of respectable standing attempting to nullify the law of nations, and declare the Supreme Court of the United States in error, because, as the Constitution forbids it, the States could not go out of the Union in fact. A respectable gentleman was lately reciting this argument, when he suddenly stopped and said, "Did you hear of that atrocious murder committed in our town? A rebel deliberately murdered a Government official." The person addressed said, "I think you are mistaken." "How so? I saw it myself." "You are wrong, no murder was or could be committed, for the law forbids it."
The theory that the rebel States, for four years a separate power and without representation in Congress, were all the time here in the Union, is a good deal less ingenious and respectable than the metaphysics of Berkeley, which proved that neither the world nor any human being was in existence. If this theory were simply ridiculous it could be forgiven; but its effect is deeply injurious to the stability of the nation. I cannot doubt that the late confederate States are out of the Union to all intents and purposes for which the conqueror may choose so to consider them.
But suppose these powerful but now subdued belligerents, instead of being out of the Union, are merely destroyed, and are now lying about, a dead corpse, or with animation so suspended as to be incapable of action, and wholly unable to heal themselves by any unaided movements of their own. Then they may fall under the provision of the Constitution, which says "The United States shall guarantee to every State in the Union a republican form of government." Under that power, can the judiciary, or the President, or the Commander-in-Chief of the Army, or the Senate or House of Representatives, acting separately, restore them to life and readmit them into the Union? I insist that if each acted separately, though the action of each was identical with all the others, it would amount to nothing. Nothing but the joint action of the two Houses of Congress and the concurrence of the President could do it. If the Senate admitted their Senators, and the House their members, it would have no effect on the future action of Congress. The Fortieth Congress might reject both. Such is the ragged record of Congress for the last four years.
