Mahlon Pitney, Detroit United Railway v. Michigan…
“ But were we in error about the construction of these ordinances, we still think that the acquisition of the city lines by plaintiff in error, and its subsequent acquisition of the suburban lines, did not bind it to put the reduced fare provisions in effect upon the suburban lines if and when the city limits should thereafter be extended to include any parts of the latter. If the city lines had been extended into the annexed territory by either of the city railway companies under any authority conferred by or assumed under the ordinances of 1889, a very different question would be presented. ”
