Which case limited Congress's power under the Commerce Clause by striking down the Gun-Free School Zones Act?

• A. Morrison
• B. Gregg
• C. McCulloch
• D. United States v. Lopez (1995)

Answer: (D)

The main concept here is the limits of Congress’s power under the Commerce Clause and how a federal law must fit within those limits to regulate a criminal activity. In United States v. Lopez, the Supreme Court struck down the Gun-Free School Zones Act because criminalizing possession of a firearm in a school zone does not fall into the categories Congress can regulate under the Commerce Clause. The Court said Congress may regulate (1) channels of interstate commerce, (2) instrumentalities of interstate commerce, or (3) activities with a substantial effect on interstate commerce. A local act that criminalizes gun possession near a school, without a clear and direct connection to interstate commerce, isn’t enough to fall within those categories. The decision emphasizes that Congress cannot use the commerce power as a general police power over non-economic activities based on a speculative link to interstate commerce. While Morrison later addressed a related, but separate, limitation involving a different statute, the question’s focus is specifically on the Gun-Free School Zones Act, making United States v. Lopez the correct example of the Commerce Clause limit in this context. The other cases involve different issues—McCulloch v. Maryland deals with federal supremacy and implied powers, and Gregg v. Georgia concerns the death penalty—so they don’t address this particular limit on Congress’s commerce power.
