514 U.S. 549 (1995)
In March 1992, Alfonso Lopez, Jr., a twelfth-grade student at Edison High School in San Antonio, Texas, arrived at school carrying a concealed .38-caliber handgun and five bullets.1 Acting on an anonymous tip, school authorities confronted Lopez, who admitted possessing the weapon.2 Local police arrested him and charged him under Texas law with firearm possession on school premises.3
The following day, state charges were dismissed after federal agents charged Lopez with violating the Gun-Free School Zones Act of 1990.4 A federal grand jury indicted him on one count of knowing possession of a firearm at a school zone.5 Lopez moved to dismiss the indictment, arguing that the statute exceeded Congress's power to legislate control over public schools.6
The district court denied the motion, concluding that the statute was a constitutional exercise of Congress's power to regulate activities affecting commerce because the business of schools affects interstate commerce.7 After a bench trial, the court found Lopez guilty and sentenced him to six months' imprisonment and two years of supervised release.8
Lopez appealed to the Court of Appeals for the Fifth Circuit, which reversed the conviction, holding that the statute was beyond Congress's power under the Commerce Clause.9 The Supreme Court granted certiorari to review the case.10
Whether the Gun-Free School Zones Act of 1990 exceeds Congress's authority under the Commerce Clause?11
The Constitution delegates to Congress the power to regulate commerce among the several States.12 U.S. Const. Art. I, § 8, cl. 3.13 Congress may regulate the use of the channels of interstate commerce.14 Congress may protect the instrumentalities of interstate commerce or persons or things in interstate commerce.15 Congress may regulate activities that substantially affect interstate commerce.16 Regulation under the third category requires that the activity be economic in nature or have a jurisdictional element ensuring a connection to interstate commerce.17 The link to commerce must not be so attenuated as to obliterate the distinction between national and local authority.18
Yes. The Gun-Free School Zones Act of 1990 is a criminal statute that by its terms has nothing to do with commerce or any sort of economic enterprise.19 It neither regulates a commercial activity nor contains a requirement that the possession be connected in any way to interstate commerce.20 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.21
Respondent was a local student at a local school.22 There is no indication that he had recently moved in interstate commerce.23 There is no requirement that his possession of the firearm have any concrete tie to interstate commerce.24 The government's essential contention that possession of a firearm in a school zone may result in violent crime and that violence affects interstate commerce through insurance costs and reduced travel, or that guns in schools threaten the educational process and thereby the nation's economic well-being, is too attenuated.25
To uphold the government's contention, the Court would have to pile inference upon inference.26
This approach would convert congressional authority under the Commerce Clause to a general police power of the sort retained by the States.27
The Gun-Free School Zones Act of 1990 exceeds Congress's authority under the Commerce Clause.28

Justice Kennedy concurs in the judgment.29 He emphasizes the history of the judicial struggle to interpret the Commerce Clause during the transition from the economic system the Founders knew to the single national market.30 That history counsels great restraint before the Court determines that the Clause is insufficient to support an exercise of national power.31
The statute operates in areas traditionally subject to state legislation, namely education and criminal law enforcement.32 The federal balance is upset when Congress regulates an activity beyond the realm of commerce without a stronger connection to commercial concerns.33 The States may perform their role as laboratories for experimentation in addressing gun possession in schools.34
Justice Thomas concurs.35 He observes that the Commerce Clause does not grant Congress authority to prohibit gun possession within 1,000 feet of a school.36 The substantial effects test has drifted far from the original understanding of the Commerce Clause.37
That test would give Congress a police power over all aspects of American life if taken to its logical extreme.38 Thomas calls for reexamination of the substantial effects test in a future case.39 The goal is to construct a standard more faithful to the text and history of the Clause while preserving the distinction between national and local matters.40
Justice Stevens dissents.41 The welfare of the future depends on the education of youth.42 The Gun-Free School Zones Act represents a considered response by Congress to a pressing national problem that has been before the Nation for some time.43
Guns are both articles of commerce and articles that can be used to restrain commerce.44 Their possession is the consequence, either directly or indirectly, of commercial activity.45 Congress's power to regulate commerce in firearms includes the power to prohibit possession of guns at any location because of their potentially harmful use.46
It necessarily follows that Congress may also prohibit their possession in particular markets.47
Justice Souter dissents.48 In reviewing congressional legislation under the Commerce Clause, courts should defer to implicit congressional judgments if there is any rational basis for finding that the regulation addresses a subject substantially affecting interstate commerce.49 The practice of deferring to rationally based legislative judgments is a paradigm of judicial restraint reflecting respect for Congress's institutional competence and political accountability.50
The majority's decision is a misstep that tugs the Court off course.51 It treats deference under the rationality rule as subject to gradation according to the commercial or noncommercial nature of the activity.52
This approach risks returning to the untenable jurisprudence of the early twentieth century by calibrating deference based on the commercial or noncommercial nature of the activity.53

Justice Breyer dissents.54 The statute falls well within the scope of the commerce power as understood over the last half century.55 The power to regulate commerce encompasses local activities that significantly affect interstate commerce.56
Courts must consider the cumulative effect of all similar instances.57 Congress is entitled to leeway in determining the existence of a significant factual connection.58 Gun-related violence in schools undermines education.59
Education is inextricably intertwined with the nation's economy through effects on worker productivity, business location decisions, and global competitiveness.60 Congress could rationally have found a substantial connection.61
