UNITED STATES, PETITIONER v. ALFONSO LOPEZ, Jr.

on writ of certiorari to the united states court of appeals for the fifth circuit

[April 26, 1995]

Chief Justice Rehnquist delivered the opinion of the Court.

On March 10, 1992, respondent, who was then a 12th grade student, arrived at Edison High School in San Antonio, Texas, carrying a concealed .38 caliber handgun and five bullets. Acting upon an anonymous tip, school authorities confronted respondent, who admitted that he was carrying the weapon. He was arrested and charged under Texas law with firearm possession on school premises. The next day, the state charges were dismissed after federal agents charged respondent by complaint with violating the Gun Free School Zones Act of 1990.

A federal grand jury indicted respondent on one count of knowing possession of a firearm at a school zone, in violation of §922(q). Respondent moved to dismiss his federal indictment on the ground that §922(q) "is unconstitutional as it is beyond the power of Congress to legislate control over our public schools." The District Court denied the motion, concluding that §922(q) "is a constitutional exercise of Congress' well defined power to regulate activities in and affecting commerce, and the `business' of elementary, middle and high schools . . . affects interstate commerce."

On appeal, respondent challenged his conviction based on his claim that §922(q) exceeded Congress' power to legislate under the Commerce Clause. The Court of Appeals for the Fifth Circuit agreed and reversed respondent's conviction.

We start with first principles. The Constitution creates a Federal Government of enumerated powers. As James Madison wrote, "[t]he powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite." The Federalist No. 45, pp. 292-293  This constitutionally mandated division of authority "was adopted by the Framers to ensure protection of our fundamental liberties."

The Constitution delegates to Congress the power "[t]o regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes."

"Commerce, undoubtedly, is traffic, but it is something more: it is intercourse. It describes the commercial intercourse between nations, and parts of nations, in all its branches, and is regulated by prescribing rules for carrying on that intercourse."

Consistent with this structure, we have identified three broad categories of activity that Congress may regulate under its commerce power. First, Congress may regulate the use of the channels of interstate commerce. Second, Congress is empowered to regulate and protect the instrumentalities of interstate commerce, or persons or things in interstate commerce, even though the threat may come only from intrastate activities. ("[F]or example, the destruction of an aircraft (18 U.S.C. § 32), or . . . thefts from interstate shipments (18 U.S.C. § 659)"). Finally, Congress' commerce authority includes the power to regulate those activities having a substantial relation to interstate commerce,

Within this final category, admittedly, our case law has not been clear whether an activity must "affect" or "substantially affect" interstate commerce in order to be within Congress' power to regulate it under the Commerce Clause. (the Court has never declared that "Congress may use a relatively trivial impact on commerce as an excuse for broad general regulation of state or private activities"). We conclude, consistent with the great weight of our case law, that the proper test requires an analysis of whether the regulated activity "substantially affects" interstate commerce.

We now turn to consider the power of Congress, in the light of this framework, to enact §922(q). The first two categories of authority may be quickly disposed of: §922(q) is not a regulation of the use of the channels of interstate commerce, nor is it an attempt to prohibit the interstate transportation of a commodity through the channels of commerce; nor can §922(q) be justified as a regulation by which Congress has sought to protect an instrumentality of interstate commerce or a thing in interstate commerce. Thus, if §922(q) is to be sustained, it must be under the third category as a regulation of an activity that substantially affects interstate commerce.

Section 922(q) is a criminal statute that by its terms has nothing to do with "commerce" or any sort of economic enterprise, however broadly one might define those terms. [n.3] Section 922(q) is not an essential part of a larger regulation of economic activity, in which the regulatory scheme could be undercut unless the intrastate activity were regulated. It cannot, therefore, be sustained under our cases upholding regulations of activities that arise out of or are connected with a commercial transaction, which viewed in the aggregate, substantially affects interstate commerce.

The Government's essential contention is that we may determine here that §922(q) is valid because possession of a firearm in a local school zone does indeed substantially affect interstate commerce. The Government argues that possession of a firearm in a school zone may result in violent crime and that violent crime can be expected to affect the functioning of the national economy in two ways. First, the costs of violent crime are substantial, and, through the mechanism of insurance, those costs are spread throughout the population. Second, violent crime reduces the willingness of individuals to travel to areas within the country that are perceived to be unsafe. The Government also argues that the presence of guns in schools poses a substantial threat to the educational process by threatening the learning environment. A handicapped educational process, in turn, will result in a less productive citizenry. That, in turn, would have an adverse effect on the Nation's economic well being. As a result, the Government argues that Congress could rationally have concluded that §922(q) substantially affects interstate commerce.

We pause to consider the implications of the Government's arguments. The Government admits, under its "costs of crime" reasoning, that Congress could regulate not only all violent crime, but all activities that might lead to violent crime, regardless of how tenuously they relate to interstate commerce. Similarly, under the Government's "national productivity" reasoning, Congress could regulate any activity that it found was related to the economic productivity of individual citizens: family law (including marriage, divorce, and child custody), for example. Under the theories that the Government presents in support of §922(q), it is difficult to perceive any limitation on federal power, even in areas such as criminal law enforcement or education where States historically have been sovereign. Thus, if we were to accept the Government's arguments, we are hard pressed to posit any activity by an individual that Congress is without power to regulate.

For instance, if Congress can, pursuant to its Commerce Clause power, regulate activities that adversely affect the learning environment, then, a fortiori, it also can regulate the educational process directly. Congress could determine that a school's curriculum has a-significant" effect on the extent of classroom learning. As a result, Congress could mandate a federal curriculum for local elementary and secondary schools because what is taught in local schools has a significant "effect on classroom learning," cf. post, at 9, and that, in turn, has a substantial effect on interstate commerce.

The possession of a gun in a local school zone is in no sense an economic activity that might, through repetition elsewhere, substantially affect any sort of interstate commerce. Respondent was a local student at a local school; there is no indication that he had recently moved in interstate commerce, and there is no requirement that his possession of the firearm have any concrete tie to interstate commerce.

To uphold the Government's contentions here, we would have to pile inference upon inference in a manner that would bid fair to convert congressional authority under the Commerce Clause to a general police power of the sort retained by the States.

Questions:  1.  Do you think that it is a good idea to have a federal law banning firearms near schools or is this a matter better handled by the states?  Why do you think Congress passed such a law in the first place?
