by John Marshall Harlan, Smyth v. Ames (69 U.S. 466) — Opinion of the Court
“ It cannot be assumed that any railroad corporation, accepting franchises, rights, and privileges at the hands of the public, ever supposed that it acquired, or that it was intended to grant to it, the power to construct and maintain a public highway simply for its benefit, without regard to the rights of the public. But it is equally true that the corporation performing such public services, and the people financially interested in its business and affairs, have rights that may not be invaded by legislative enactment in disregard of the fundamental guaranties for the protection of property. ”
