Morrison Waite,
Canada Southern Railway Company v…
“ If any state in this Union should assume to pass a law with reference to a railway corporation she had created, requiring the holders of its bonds, for which they had paid value, to surrender them and take in their place others of less value, and payable at a different time, our courts, federal and state, would be constrained, by their obligation to support the constitution of the United States, to declare such legislation to be in conflict with that instrument. ”
