What did Gibbons v. Ogden decide about interstate commerce?

• A. It ruled that only states may regulate interstate commerce.
• B. It held that Congress may regulate interstate commerce, including navigation, expanding federal authority.
• C. It allowed local governments to regulate interstate commerce.
• D. It restricted Congress to regulate only intrastate commerce.

Answer: (B)

The main idea here is how the Commerce Clause shapes federal power over trade that crosses state lines, including the channels of travel and transport. In Gibbons v. Ogden, the Supreme Court ruled that Congress has authority to regulate interstate commerce, and that this includes navigation between states. This broad interpretation meant federal law can govern ferry and steamboat operations that cross state boundaries, even when a state grants a monopoly. It also established federal supremacy in matters touching interstate commerce and broadened what counts as commerce to cover the channels and intercourse between states, not just the buying and selling of goods. So, Congress can regulate interstate commerce, including navigation, expanding federal authority beyond purely intrastate or locally controlled activities.
