Has Congress constitutional power to make such a law? Of course, no one will contend that the power to pass it was contained in the Constitution before the adoption of the last three amendments. The power is sought, first, in the Fourteenth Amendment, and the views and arguments of distinguished Senators, advanced whilst the law was under consideration, claiming authority to pass it by virtue of that amendment, are the principal arguments adduced in favor of the power. We have carefully considered those arguments, as was due to the eminent ability of those who put them forward, and have felt, in all its force, the weight of authority which always invests a law that Congress deems itself competent to pass. But the responsibility of an independent judgment is now thrown upon this court; and we are bound to exercise it according to the best lights we have. The first section of the Fourteenth Amendment (which is the one relied on), after declaring who shall be citizens of the United States, and of the several States, is prohibitory in its character, and prohibitory upon the States. It declares that: “No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty or property without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.” It is State action of a particular character that is prohibited. Individual invasion of individual rights is not the subject-matter of the amendment. It has a deeper and broader scope. It nullifies and makes void all State legislation and State action of every kind which impairs the privileges and immunities of citizens of the United States, or which injures them in life, liberty or property without due process of law, or which denies to any of them the equal protection of the laws. It not only does this, but in order that the national will thus declared may not be a mere _brutum fulmen_, the last section of the amendment invests Congress with power to enforce it by appropriate legislation. To enforce what? To enforce the prohibition. To adopt appropriate legislation for correcting the effects of such prohibited State laws and State acts, and thus to render them effectually null, void and innocuous. This is the legislative power conferred upon Congress, and this is the whole of it. It does not invest Congress with power to legislate upon subjects which are within the domain of State legislation; but to provide modes of relief against State legislation or State action of the kind referred to. It does not authorize Congress to create a code of municipal law for the regulation of private rights; but to provide modes of redress against the operation of State laws, and the action of State officers, executive or judicial, when these are subversive of the fundamental rights specified in the amendment.
