by John Marshall Harlan, Madisonville Traction Company v…
“ There ought not to be any dispute, at this day, in reference to the principles which must control in all cases of the condemnation of private property for public purposes. It is fundamental in American jurisprudence that private property cannot be taken by the government, national or state, except for purposes which are of a public character, although such taking be accompanied by compensation to the owner. That principle, this court has said, grows out of the essential nature of all free governments. ”
