It will hardly be contended, that all these acts are consistent with the laws and Constitution of the United States. If there is no power in the general government to control this extreme belligerent legislation of the States, the powers of the government are essentially deficient in a most important and interesting particular. The present controversy respects the earliest of these State laws, those of New York. On these, this court is now to pronounce; and if they should be declared to be valid and operative, I hope somebody will point out where the State right stops, and on what grounds the acts of other States are to be held inoperative and void. It will be necessary to advert more particularly to the laws of New York, as they are stated in the record. The first was passed March 19th, 1787. By this act, a sole and exclusive right was granted to John Fitch, of making and using every kind of boat or vessel impelled by steam, in all creeks, rivers, bays, and waters within the territory and jurisdiction of New York for fourteen years. On the 27th of March, 1798, an act was passed, on the suggestion that Fitch was dead, or had withdrawn from the State without having made any attempt to use his privilege, repealing the grant to him, and conferring similar privileges on Robert R. Livingston, for the term of twenty years, on a suggestion, made by him, that he was possessor of a mode of applying the steam-engine to propel a boat, on new and advantageous principles. On the 5th of April, 1803, another act was passed, by which it was declared, that the rights and privileges granted to Robert R. Livingston by the last act should be extended to him and Robert Fulton, for twenty years from the passing of the act. Then there is the act of April 11, 1808, purporting to extend the monopoly, in point of time, five years for every additional boat, the whole duration, however, not to exceed thirty years; and forbidding any and all persons to navigate the waters of the State with any steam boat or vessel, without the license of Livingston and Fulton, under penalty of forfeiture of the boat or vessel. And lastly comes the act of April 9, 1811, for enforcing the provisions of the last-mentioned act, and declaring, that the forfeiture of the boat or vessel found navigating against the provisions of the previous acts shall be deemed to accrue on the day on which such boat or vessel should navigate the waters of the State; and that Livingston and Fulton might immediately have an action for such boat or vessel, in like manner as if they themselves had been dispossessed thereof by force; and that, on bringing any such suit, the defendant therein should be prohibited, by injunction, from removing the boat or vessel out of the State, or using it within the State. There are one or two other acts mentioned in the pleadings, which principally respect the time allowed for complying with the condition of the grant, and are not material to the discussion of the case.
