I concur in the opinion which has just been read by Mr. Justice Field; but desire to add a few observations for the purpose of more fully illustrating my views on the important question decided in these cases, and the special grounds on which they rest.
The fourteenth amendment to the Constitution of the United States, section 1, declares that no State shall make or enforce any law which shall abridge the privileges and immunities of citizens of the United States.
The legislature of Louisiana, under pretence of making a police regulation for the promotion of the public health, passed an act conferring upon a corporation, created by the act, the exclusive right, for twenty-five years, to have and maintain slaughter-houses, landings for cattle, and yards for confining cattle intended for slaughter, within the parishes of Orleans, Jefferson, and St. Bernard, a territory containing nearly twelve hundred square miles, including the city of New Orleans; and prohibiting all other persons from building, keeping, or having slaughter-houses, landings for cattle, and yards for confining cattle intended for slaughter within the said limits; and requiring that all cattle and other animals to be slaughtered for food in that district should be brought to the slaughter-houses and works of the favored company to be slaughtered, and a payment of a fee to the company for such act.
It is contended that this prohibition abridges the privileges and immunities of citizens of the United States, especially of the plaintiffs in error, who were particularly affected thereby; and whether it does so or not is the simple question in this case. And the solution of this question depends upon the solution of two other questions, to wit:
First. Is it one of the rights and privileges of a citizen of the United States to pursue such civil employment as he may choose to adopt, subject to such reasonable regulations as may be prescribed by law?
Secondly. Is a monopoly, or exclusive right, given to one person to the exclusion of all others, to keep slaughter-houses, in a district of nearly twelve hundred square miles, for the supply of meat for a large city, a reasonable regulation of that employment which the legislature has a right to impose?
The first of these questions is one of vast importance, and lies at the very foundations of our government. The question is now settled by the fourteenth amendment itself, that citizenship of the United States is the primary citizenship in this country; and that State citizenship is secondary and derivative, depending upon citizenship of the United States and the citizen's place of residence. The States have not now, if they ever had, any power to restrict their citizenship to any classes or persons. A citizen of the United States has a perfect constitutional right to go to and reside in any State he chooses, and to claim citizenship therein, and an equality of rights with every other citizen; and the whole power of the nation is pledged to sustain him in that right. He is not bound to cringe to any superior, or to pray for any act of grace, as a means of enjoying all the rights and privileges enjoyed by other citizens. And when the spirit of lawlessness, mob violence, and sectional hate can be so completely repressed as to give full practical effect to this right, we shall be a happier nation, and a more prosperous one than we now are. Citizenship of the United States ought to be, and, according to the Constitution, is, a surt and undoubted title to equal rights in any and every States in this Union, subject to such regulations as the legislature may rightfully prescribe. If a man be denied full equality before the law, he is denied one of the essential rights of citizenship as a citizen of the United States.
Every citizen, then, being primarily a citizen of the United States, and, secondarily, a citizen of the State where he resides, what, in general, are the privileges and immunites of a citizen of the United States? Is the right, liberty, or privilege of choosing any lawful employment one of them?
