It is due to myself to say, that it is asking much of a judge, who has for nearly twenty years been exercising jurisdiction, from the western Missouri line to the Rocky Mountains, and, on this understanding of the Constitution, inflicting the extreme penalty of death for crimes committed where the direct legislation of Congress was the only rule, to agree that he had been all the while acting in mistake, and as an usurper.
More than sixty years have passed away since Congress has exercised power to govern the Territories, by its legislation directly, or by Territorial charters, subject to repeal at all times, and it is now too late to call that power into question, if this court could disregard its own decisions; which it cannot do, as I think. It was held in the case of Cross v. Harrison, (16 How., 193-'4,) that the sovereignty of California was in the United States, in virtue of the Constitution, by which power had been given to Congress to dispose of and make all needful rules and regulations respecting the territory or other property belonging to the United States, with the power to admit new States into the Union. That decision followed preceding ones, there cited. The question was then presented, how it was possible for the judicial mind to conceive that the United States Government, created solely by the Constitution, could, by a lawful treaty, acquire territory over which the acquiring power had no jurisdiction to hold and govern it, by force of the instrument under whose authority the country was acquired; and the foregoing was the conclusion of this court on the proposition. What was there announced, was most deliberately done, and with a purpose. The only question here is, as I think, how far the power of Congress is limited.
As to the Northwest Territory, Virginia had the right to abolish slavery there; and she did so agree in 1787, with the other States in the Congress of the Confederation, by assenting to and adopting the ordinance of 1787, for the government of the Northwest Territory. She did this also by an act of her Legislature, passed afterwards, which was a treaty in fact.
Before the new Constitution was adopted, she had as much right to treat and agree as any European Government had. And, having excluded slavery, the new Government was bound by that engagement by article six of the new Constitution. This only meant that slavery should not exist whilst the United States exercised the power of government, in the Territorial form; for, when a new State came in, it might do so, with or without slavery.
My opinion is, that Congress had no power, in face of the compact between Virginia and the twelve other States, to force slavery into the Northwest Territory, because there, it was bound to that "engagement," and could not break it.
In 1790, North Carolina ceded her western territory, now the State of Tennessee, and stipulated that the inhabitants thereof should enjoy all the privileges and advantages of the ordinance for governing the territory north of the Ohio river, and that Congress should assume the government, and accept the cession, under the express conditions contained in the ordinance: Provided, "That no regulation made, or to be made, by Congress, shall tend to emancipate slaves."
In 1802, Georgia ceded her western territory to the United States, with the provision that the ordinance of 1787 should in all its parts extend to the territory ceded, "that article only excepted which forbids slavery." Congress had no more power to legislate slavery out from the North Carolina and Georgia cessions, than it had power to legislate slavery in, north of the Ohio. No power existed in Congress to legislate at all, affecting slavery, in either case. The inhabitants, as respected this description of property, stood protected whilst they were governed by Congress, in like manner that they were protected before the cession was made, and when they were, respectively, parts of North Carolina and Georgia.
And how does the power of Congress stand west of the Mississippi river? The country there was acquired from France, by treaty, in 1803. It declares, that the First Consul, in the name of the French Republic, doth hereby cede to the United States, in full sovereignty, the colony or province of Louisiana, with all the rights and appurtenances of the said territory. And, by article third, that "the inhabitants of the ceded territory shall be incorporated in the Union of the United States, and admitted as soon as possible, according to the principles of the Federal Constitution, to the enjoyment of all the rights, advantages, and immunities, of citizens of the United States; and, in the mean time, they shall be maintained and protected in the free enjoyment of their liberty, property, and the religion which they profess."
Louisiana was a province where slavery was not only lawful, but where property in slaves was the most valuable of all personal property. The province was ceded as a unit, with an equal right pertaining to all its inhabitants, in every part thereof, to own slaves. It was, to a great extent, a vacant country, having in it few civilized inhabitants. No one portion of the colony, of a proper size for a State of the Union had a sufficient number of inhabitants to claim admission into the Union. To enable the United States to fulfil the treaty, additional population was indispensable, and obviously desired with anxiety by both sides, so that the whole country should, as soon as possible, become States of the Union. And for this contemplated future population, the treaty as expressly provided as it did for the inhabitants residing in the province when the treaty was made. All these were to be protected "in the mean time;" that is to say, at all times, between the date of the treaty and the time when the portion of the Territory where the inhabitants resided was admitted into the Union as a State.
At the date of the treaty, each inhabitant had the right to the free enjoyment of his property, alike with his liberty and his religion, in every part of Louisiana; the province then being one country, he might go everywhere in it, and carry his liberty, property, and religion, with him, and in which he was to be maintained and protected, until he became a citizen of a State of the Union of the United States. This cannot be denied to the original inhabitants and their descendants. And, if it be true that immigrants were equally protected, it must follow that they can also stand on the treaty.
