How did Marshall rule in the case of Gibbons vs. Ogden?

In 1819 Ogden sued Thomas Gibbons, who was operating steamboats in the same waters without the authority of Fulton and Livingston. Ogden won in 1820 in the New York Court of Chancery. Gibbons appealed to the U. S. Supreme Court, contending that he was protected by terms of a federal license to engage in coasting trade.
