No one, we presume, supposes that any change in public opinion or feeling, in relation to this unfortunate race, in the civilized nations of Europe or in this country, should induce the court to give to the words of the Constitution a more liberal construction in their favor than they were intended to bear when the instrument was framed and adopted. Such an argument would be altogether inadmissible in any tribunal called on to interpret it. If any of its provisions are deemed unjust, there is a mode prescribed in the instrument itself by which it may be amended; but while it remains unaltered, it must be construed now as it was understood at the time of its adoption. It is not only the same in words, but the same in meaning, and delegates the same powers to the Government, and reserves and secures the same rights and privileges to the citizen; and as long as it continues to exist in its present form, it speaks not only in the same words, but with the same meaning and intent with which it spoke when it came from the hands of its framers, and was voted on and adopted by the people of the United States. Any other rule of construction would abrogate the judicial character of this court, and make it the mere reflex of the popular opinion or passion of the day. This court was not created by the Constitution for such purposes. Higher and graver trusts have been confided to it, and it must not falter in the path of duty. What the construction was at that time, we think can hardly admit of doubt. We have the language of the Declaration of Independence and of the Articles of Confederation, in addition to the plain words of the Constitution itself; we have the legislation of the different States, before, about the time, and since, the Constitution was adopted; we have the legislation of Congress, from the time of its adoption to a recent period; and we have the constant and uniform action of the Executive Department, all concurring together, and leading to the same result. And if anything in relation to the construction of the Constitution can be regarded as settled, it is that which we now give to the word "citizen" and the word "people." And upon a full and careful consideration of the subject, the court is of opinion, that, upon the facts stated in the plea in abatement, Dred Scott was not a citizen of Missouri within the meaning of the Constitution of the United States, and not entitled as such to sue in its courts; and, consequently, that the Circuit Court had no jurisdiction of the case, and that the judgment on the plea in abatement is erroneous.
