In the _Louisville Railway Company_ v. _Mississippi_,[31] however, in 1899, the court, evidently yielding to southern public opinion, reversed itself by the decision that an interstate carrier could not run a train through Mississippi without attaching thereto a separate car for Negroes and had the audacity to argue that this is not an interference with interstate commerce.[32] To show how inconsistent this interpretation was one should bear in mind that in _Hall_ v. _DeCuir_ the court had held that this was exactly what a State could not do in that the statute acted not upon business through local instruments to be employed after coming into the State, but directly upon business as it comes into the State from without or goes out from within, although it purported only to control the carrier when engaged within the State. It necessarily influenced the conduct of the carrier to some extent in the management of his business throughout his entire voyage. "No carrier of passengers," said the court in _Hall_ v. _DeCuir_, "can conduct his business with satisfaction to himself, or comfort to those employing him, if on one side of a State line his passengers, both white and colored, must be permitted to occupy the same cabin, and on the other to be kept separate. Uniformity in the regulation by which he is to be governed from one end to the other of his route is a necessity in his business, and to secure it, Congress, which is untrammelled by State lines, has been invested with exclusive legislative power of determining what such regulation should be." Giving the opinion in the Mississippi case, however, Justice Brewer said: "It has been often held by this court that there is a commerce wholly within the State which is not subject to the constitutional provision and the distinctions between commerce among the States and the other class of commerce between citizens of a single State and conducted within its limits exclusively is one which has been fully recognized in this court, although it may not be always easy, where the lines of these classes approach each other, to distinguish between the one and the other."[33] He might have added some other comment to the effect that this court will not definitely draw the line of distinction between such classes of commerce since it desires to leave adequate room for evasion, because it had been unusually easy to find such a line in cases in which the rights of Negroes were concerned and such definite interpretation might interfere with the rights of white men. Justices Harlan and Bradley dissented on the grounds that the law imposed a burden upon an interstate carrier in that he would be fined if he did not attach an additional car for race discrimination, and that the opinion was repugnant to the principles set forth in that of _Hall_ v. _DeCuir_.
