“ If the state may not thus legislate as to its domestic corporations, they, by merely arbitrary action, may so exercise their ratefixing power as to build up one community and destroy another, and prevent that equality of treatment which it has been the object of many statutes of this kind, passed under state and Federal authority, to secure. The statute does not define unjust discrimination, but leaves it to the commission, upon hearing, to determine what rates are unjust and discriminatory, and to make orders for other fares, which, in its judgment, are not open to such objection. ”

“ The statute expressly provides for a judicial review by the courts of the orders of the commission to test the lawfulness of the fares fixed and the reasonableness of regulations prescribed by the commission. We find nothing in the 14th Amendment which prevents a state from making provision for such relief to communities unjustly discriminated against by companies subject to the laws of the state in which they operate, and from which they derive their powers as common carriers and public-service corporations. ”

“ This construction of the statute is binding upon this court, and it is to be considered as thus construed by the supreme court of Oregon.
The authority of the states to control by appropriate legislation the rates of fare to be charged by street railway companies and other common carriers wholly within their borders and subject to their laws is unquestionable. In the legitimate exercise of such authority we see no reason why a state may not, consistently with due process of law, prohibit any unjust discrimination by a domestic railroad company against certain localities upon its lines. ”
