Case
United States v. Lopez
United States v. Lopez (1995) held that Congress exceeded its Commerce Clause power by criminalizing mere possession of a gun in a local school zone. The Court articulated three commerce categories, emphasized the non‑economic nature of the conduct, noted the absence of a jurisdictional hook, and rejected attenuated economic effects. The final clue pins the 1995 case.
Rule to remember
United States v. Lopez, 514 U.S. 549 (1995), is the Supreme Court decision limiting Congress’s Commerce Clause power by striking down the Gun‑Free School Zones Act’s ban on mere possession near schools.
Key elements and checks
- Commerce Clause categories: channels; instrumentalities/persons/things; activities that substantially affect interstate commerce.
- The regulated conduct—mere gun possession near a school—was non‑economic.
- No jurisdictional element in § 922(q) to require a case‑by‑case interstate nexus.
- Insufficient congressional findings; economic effects were too attenuated to aggregate.
- Rule: Non‑economic criminal activity generally cannot be aggregated to show substantial effects.
- Contrast: comprehensive regulation of an economic market may be sustained; non‑economic civil remedies are not.
In the source’s words
“Consistent with this structure, we have identified three broad categories of activity that Congress may regulate under its commerce power.”

“The possession of a gun in a local school zone is in no sense an economic activity”

This is federal constitutional doctrine; state variation is limited. States, exercising general police powers, may enact their own gun‑free school‑zone laws. After this decision, Congress amended § 922(q) to add an interstate‑commerce jurisdictional element; many courts have since upheld the amended provision.
