Gibbons v. Ogden established which interpretation of federal power over commerce?

• A. Congress has the power to regulate commerce and federal law takes precedence over state laws.
• B. States retain exclusive control over intrastate commerce.
• C. The judiciary is the sole interpreter of commerce power.
• D. Federal law cannot override conflicting state commerce regulations.

Answer: (A)

The main idea here is that Congress has the power to regulate interstate commerce, and when federal regulation conflicts with state laws, the federal rule wins. Gibbons v. Ogden dealt with competing steamboat licenses and held that federal regulation of interstate navigation falls under Congress’s commerce power. The Court said the federal license governed interstate travel and commerce, not a state-granted monopoly, because the federal regulation is intended to regulate commerce that crosses state lines.

This decision also ties into the Supremacy Clause: when federal law and state law clash, federal law preempts the state law. So the case establishes a broad view of commerce power—covering more than mere goods traded across borders and extending to navigation and other activities that affect interstate commerce. It rejects the notion that states hold exclusive control over all commerce within their borders and reinforces that federal authority can override state regulations when they interfere with interstate commerce.
