Let it be further supposed that Congress, believing that they do possess the power, have passed an act for those purposes, under which commissioners have been appointed, who have begun the work. They are met at the first farm on which they enter by the owner, who forbids them to trespass on his land. They offer to buy it at a fair price or at twice or thrice its value. He persists in his refusal. Can they, on the principle recognized and acted on by all the State governments that in cases of this kind the obstinacy and perverseness of an individual must yield to the public welfare, summon a jury of upright and discreet men to condemn the land, value it, and compel the owner to receive the amount and to deliver it up to them? I believe that very few would concur in the opinion that such a power exists.
The next object is to preserve these improvements from injury. The locks of the canal are broken, the walls which sustained the road are pulled down, the bridges are broken, the road itself is plowed up, toll is refused to be paid, the gates of the canal or turnpike are forced. The offenders are pursued, caught, and brought to trial. Can they be punished? The question of right must be decided on principle. The culprits will avail themselves of every barrier that may serve to screen them from punishment. They will plead that the law under which they stand arraigned is unconstitutional, and that question must be decided by the court, whether Federal or State, on a fair investigation of the powers vested in the General Government by the Constitution. If the judges find that these powers have not been granted to Congress, the prisoners must be acquitted, and by their acquittal all claim to the right to establish such a system is at an end.
