What is the significance of the Commerce Clause in expanding federal power, exemplified by Gibbons v. Ogden?

• A. It affirmed federal authority over interstate commerce, enabling broad regulatory power for the national government.
• B. It limited federal power and expanded states' rights.
• C. It created the judiciary as the sole arbiter of commerce.
• D. It restricted the federal government's ability to regulate trade with foreign nations.

Answer: (A)

The core idea is that the Commerce Clause gives Congress power to regulate activity that crosses state lines, and Gibbons v. Ogden shows how far that power can go. In this 1824 decision, the Supreme Court interpreted interstate commerce very broadly, ruling that federal authority includes navigation and other forms of commercial activity between states, not just purely transactional trade approved by state laws. Because one party held a state-granted monopoly over steamboat navigation, the case pitted state control against a federal licensing regime, and the Court decided that federal regulation predominates in interstate commerce. That means Congress can regulate not only the movement of goods but also the channels and practices that shape a national market, strengthening federal power relative to the states.

So the best choice captures that expansion of federal authority to regulate interstate commerce, enabling the national government to pursue broad regulatory power. The other options describe limits or roles that don’t fit what Gibbons v. Ogden established.
