Giving the opinion of the court in Civil Rights Cases,[19] Mr. Justice Bradley said that the Fourteenth Amendment on which this act of 1875 rested for its authority, if it had any authority at all, does not invest Congress to legislate within the domain of State legislation or in State action of the kind referred to in the Civil Rights Act. He believed that the Fourteenth Amendment does not authorize Congress to create a code of municipal law for the regulation of private rights. He conceded that positive rights and privileges are secured by the Fourteenth Amendment but only by prohibition against State laws and State proceedings affecting those rights.[20] "Until some State law has passed," he said, "or some State action through its officers or agents has been taken, adverse to the rights of citizens sought to be protected by the Fourteenth Amendment, no legislation of the United States under said amendment, nor any proceeding under such legislation, can be called into activity; for the prohibitions of the amendment are against State laws and acts under State authority." Otherwise Congress would take the place of State legislatures and supersede them and regulate all private rights between man and man. Civil rights such as are guaranteed by the Constitution against State aggression, thought Justice Bradley, cannot be impaired by the wrongful acts of individuals unsupported by State authority in the shape of laws, customs, or executive proceedings, for those are private wrongs.
