This unanimous decision the New York Court for the Correction of Errors upheld the thirty-year monopoly on steamboat navigation on the Hudson River granted by the state legislature to Fulton and Livingston. This pamphlet contains the opinions of the court’s three judges: Joseph C. Yates [1768-1837], Smith Thompson [1768-1843] and James Kent [1763-1847]. The longest of these is by Kent, the chief justice. A few years later another steamboat entrepreneur, Thomas Gibbons, defied the law and established a ferry line between New York and New Jersey. This led to the 1824 U.S. Supreme Court ruling Gibbons v. Ogden. Declaring that states cannot regulate interstate commerce, the court struck down Fulton's monopoly.
