Raymond v. Chicago Union Traction Company‪.‬

The claim that the action of the state board of equalization in making the assessment under consideration was the action of the State, and if carried out would violate the provisions of the Fourteenth Amendment to the Constitution of the United States, by taking property of the appellee without due process of law, and by failing to give it the equal protection of the laws, constitutes a Federal question beyond all controversy. How that question should be decided is another matter which we will proceed at once to discuss.
