Gibbons v. Ogden
The Supreme Court struck down New York's steamboat monopoly, ruling that the federal government's power to regulate interstate commerce — which includes navigation — overrides state laws that conflict with it.
The decision broadly defined 'commerce' to encompass navigation and all forms of commercial intercourse, establishing that a valid federal coasting-trade license protects operators from state-imposed restrictions on the same activity and that federal law is supreme when the two conflict.
“Commerce, undoubtedly, is traffic, but it is something more: it is intercourse. It describes the commercial intercourse between nations, and parts of nations, in all its branches, and is regulated by prescribing rules for carrying on that intercourse.”
Chief Justice Marshall defines 'commerce' broadly to include navigation and all forms of intercourse, not merely buying and selling.
Why this is a landmark case
Gibbons v. Ogden gave the first broad interpretation of the Commerce Clause and established federal supremacy over the national economy. New York had granted a monopoly over steamboat navigation in its waters; Marshall's Court held that this conflicted with a federal coasting-license law and was therefore invalid under the Supremacy Clause.
Marshall defined 'commerce' expansively to include not just buying and selling but navigation and the broader channels of trade among the states, and he held that the federal power over interstate commerce is plenary. The ruling broke the power of state-granted monopolies and helped knit the country into a single national market.
Its significance is structural and lasting: Gibbons supplied the constitutional foundation for the vast expansion of federal economic regulation in the twentieth century, from antitrust and labor law to civil-rights statutes upheld on commerce grounds. Together with McCulloch, it cemented Marshall's vision of a powerful national government and remains the starting point for any analysis of Congress's commerce power.
The Case in Depth
What happened
New York State granted Robert Livingston and Robert Fulton an exclusive thirty-year monopoly to operate steam-powered boats on all New York waters. Aaron Ogden obtained a sublicense under this monopoly to run steamboats between New Jersey and New York City. Thomas Gibbons also operated steamboats on the same route, but under a federal enrollment and license issued pursuant to the Coasting Trade Act of 1793. Ogden sued Gibbons in New York courts to enforce the state monopoly and stop Gibbons's boats.
The question before the Court
Could New York State grant a handful of steamboat operators the exclusive right to navigate New York waters by steam, even against someone holding a federal license to conduct the coasting trade?
The Court's answer
No — New York could not use its steamboat monopoly to block a federally licensed operator from navigating New York waters. The Court held that Congress's power to regulate commerce among the states is broad enough to include navigation, not just buying and selling of goods. Because Congress had exercised that power by passing the Coasting Trade Act — which granted Thomas Gibbons's steamboats a license to engage in the coasting trade — New York's monopoly law directly collided with a valid federal statute.
Under the Constitution's Supremacy Clause, federal law prevails in any such collision. The state monopoly was void to the extent it prevented Gibbons from operating his federally licensed vessels, and the permanent injunction the New York courts had issued against him was reversed and the lawsuit against him dismissed.

How the Court got there
The legal reasoning, step by step
- The Court first settled what 'commerce' means in the Constitution. It rejected the narrow view that commerce means only buying and selling. Commerce is 'something more: it is intercourse' — describing commercial intercourse between nations and parts of nations in all its branches, including navigation. The Court found this understanding universal: all Americans had always read 'commerce' to include navigation, and the Constitution's own references to vessels and embargoes confirmed it.
- The power to regulate commerce 'among the several States' extends into the interior of each state wherever interstate commerce takes place — it cannot stop at a state's external boundary line, or it would be almost useless. Congress's commerce power, once exercised on a subject, is complete in itself and acknowledges no limitations other than those spelled out in the Constitution. It includes the power to regulate navigation of all waters connected with foreign or interstate commerce.
- The Court distinguished the commerce power from the taxing power to explain why states may levy taxes alongside Congress but cannot simultaneously regulate the same interstate commerce. Taxation by two governments on different subjects does not inherently conflict. But when a state regulates the very commerce Congress is already regulating, it is doing the same thing the Constitution assigned exclusively to Congress — a direct conflict, not a mere parallel exercise.
- State laws like quarantine rules, inspection laws, and ferry regulations that incidentally touch commercial activity are not actually exercises of the commerce power — they flow from the states' reserved powers over health, safety, and internal police. The Court upheld these as valid precisely because they originate from a different source of authority, not from the power to regulate interstate commerce that the Constitution transferred to Congress.
- Congress exercised its commerce power by passing the Coasting Trade Act, which enrolled and licensed specific vessels to carry on the coasting trade. The Court read the license not as a mere certificate of national identity but as a genuine legislative permission to operate: the Act's text declares enrolled and licensed vessels 'entitled to the privileges of ships or vessels employed in the coasting trade,' and those privileges are empty unless they include the right to actually conduct that trade.
- New York's monopoly law prohibited Gibbons's steam-powered, federally licensed vessels from navigating New York waters, directly conflicting with the federal license that authorized precisely that navigation. Under the Supremacy Clause, the state law yielded to the federal statute wherever the two clashed — regardless of whether the state law was otherwise a valid exercise of acknowledged state powers.
