I will examine each which can have any possible bearing on this question.
The first clause of the second section of the third article of the Constitution is, "The judicial power shall extend to controversies between a State and citizens of another State; between citizens of different States; between citizens of the same State, claiming lands under grants of different States; and between States, or the citizens thereof, and foreign States, citizens, or subjects." I do not think this clause has any considerable bearing upon the particular inquiry now under consideration. Its purpose was, to extend the judicial power to those controversies into which local feelings or interests might so enter as to disturb the course of justice, or give rise to suspicions that they had done so, and thus possibly give occasion to jealousy or ill will between different States, or a particular State and a foreign nation. At the same time, I would remark, in passing, that it has never been held, I do not know that it has ever been supposed, that any citizen of a State could bring himself under this clause and the eleventh and twelfth sections of the judiciary act of 1789, passed in pursuance of it, who was not a citizen of the United States. But I have referred to the clause, only because it is one of the places where citizenship is mentioned by the Constitution. Whether it is entitled to any weight in this inquiry or not, it refers only to citizenship of the several States; it recognises that; but it does not recognise citizenship of the United States as something distinct therefrom.
As has been said, the purpose of this clause did not necessarily connect it with citizenship of the United States, even if that were something distinct from citizenship of the several States, in the contemplation of the Constitution. This cannot be said of other clauses of the Constitution, which I now proceed to refer to.
"The citizens of each State shall be entitled to all the privileges and immunities of citizens of the several States." Nowhere else in the Constitution is there anything concerning a general citizenship; but here, privileges and immunities to be enjoyed throughout the United States, under and by force of the national compact, are granted and secured. In selecting those who are to enjoy these national rights of citizenship, how are they described? As citizens of each State. It is to them these national rights are secured. The qualification for them is not to be looked for in any provision of the Constitution or laws of the United States. They are to be citizens of the several States, and, as such, the privileges and immunities of general citizenship, derived from and guarantied by the Constitution, are to be enjoyed by them. It would seem that if it had been intended to constitute a class of native-born persons within the States, who should derive their citizenship of the United States from the action of the Federal Government, this was an occasion for referring to them. It cannot be supposed that it was the purpose of this article to confer the privileges and immunities of citizens in all the States upon persons not citizens of the United States.
And if it was intended to secure these rights only to citizens of the United States, how has the Constitution here described such persons? Simply as citizens of each State.
But, further: though, as I shall presently more fully state, I do not think the enjoyment of the elective franchise essential to citizenship, there can be no doubt it is one of the chiefest attributes of citizenship under the American Constitutions; and the just and constitutional possession of this right is decisive evidence of citizenship. The provisions made by a Constitution on this subject must therefore be looked to as bearing directly on the question what persons are citizens under that Constitution; and as being decisive, to this extent, that all such persons as are allowed by the Constitution to exercise the elective franchise, and thus to participate in the Government of the United States, must be deemed citizens of the United States.
Here, again, the consideration presses itself upon us, that if there was designed to be a particular class of native-born persons within the States, deriving their citizenship from the Constitution and laws of the United States, they should at least have been referred to as those by whom the President and House of Representatives were to be elected, and to whom they should be responsible.
Instead of that, we again find this subject referred to the laws of the several States. The electors of President are to be appointed in such manner as the Legislature of each State may direct, and the qualifications of electors of members of the House of Representatives shall be the same as for electors of the most numerous branch of the State Legislature.
Laying aside, then, the case of aliens, concerning which the Constitution of the United States has provided, and confining our view to free persons born within the several States, we find that the Constitution has recognised the general principle of public law, that allegiance and citizenship depend on the place of birth; that it has not attempted practically to apply this principle by designating the particular classes of persons who should or should not come under it; that when we turn to the Constitution for an answer to the question, what free persons, born within the several States, are citizens of the United States, the only answer we can receive from any of its express provisions is, the citizens of the several States are to enjoy the privileges and immunities of citizens in every State, and their franchise as electors under the Constitution depends on their citizenship in the several States. Add to this, that the Constitution was ordained by the citizens of the several States; that they were "the people of the United States," for whom and whose posterity the Government was declared in the preamble of the Constitution to be made; that each of them was "a citizen of the United States at the time of the adoption of the Constitution," within the meaning of those words in that instrument; that by them the Government was to be and was in fact organized; and that no power is conferred on the Government of the Union to discriminate between them, or to disfranchise any of them—the necessary conclusion is, that those persons born within the several States, who, by force of their respective Constitutions and laws, are citizens of the State, are thereby citizens of the United States.
It may be proper here to notice some supposed objections to this view of the subject.
