George Shiras, Jr.,
St. Joseph Company v. Steele — Opinion of the Court
“ We cannot accede to the proposition that because the acts of congress which authorized the construction of the bridge in question gave the right to build a railroad and toll bridge, the conceded power of the state to tax did not extend to the bridge in both aspects. Nor can we agree that the making of such a contention raised a federal question of a character to confer original jurisdiction in the circuit court of the United States. Not every mere allegation of the existence of a federal question in a controversy will suffice for that purpose. ”
