Dissent in United States v. Lopez
514 U.S. 549 (1995) (1995) · Supreme Court of the United States
United States v. Lopez was the first case in nearly sixty years in which the Supreme Court struck down a federal statute as exceeding Congress's Commerce Clause power. The decision reestablished that the Commerce Clause has judicially enforceable limits and articulated a three-category framework for analyzing commerce power that remains the governing test today.
What was the dissent in United States v. Lopez?
Justice Breyer, joined by Justices Stevens, Souter, and Ginsburg, dissented, arguing that gun-related violence near schools substantially affects interstate commerce through its impact on education, workforce productivity, and the national economy. The dissent contended that the majority's approach was inconsistent with the Court's post-New Deal Commerce Clause precedents and improperly limited Congress's rational basis for finding a commercial nexus.
Case Overview
Facts
Alfonso Lopez Jr., a twelfth-grade student at Edison High School in San Antonio, Texas, carried a concealed .38 caliber handgun and five bullets into school. He was initially charged under Texas state law, but those charges were dismissed after he was charged under the federal Gun-Free School Zones Act of 1990, which made it a federal offense to knowingly possess a firearm in a school zone. Lopez moved to dismiss, arguing the statute exceeded Congress's commerce power.
Majority Holding
The Court held 5-4 that the Gun-Free School Zones Act exceeded Congress's commerce power. Chief Justice Rehnquist's opinion identified three categories of activity Congress may regulate under the Commerce Clause and held that gun possession near schools did not fall within any of them. The statute neither regulated the channels of interstate commerce, the instrumentalities of interstate commerce, nor activities having a substantial relation to interstate commerce.
Majority Reasoning
Chief Justice Rehnquist articulated three categories of permissible Commerce Clause regulation: (1) the channels of interstate commerce, (2) the instrumentalities of or persons and things in interstate commerce, and (3) activities that substantially affect interstate commerce. Gun possession in a school zone was not an economic or commercial activity, and the Act contained no jurisdictional element tying each case to interstate commerce. The government's argument that guns in schools affect the economy through their impact on education and productivity would convert the Commerce Clause into a general police power, obliterating the distinction between what is national and what is local.
The Dissenting Opinion
Justice Breyer, joined by Justices Stevens, Souter, and Ginsburg, dissented, arguing that gun-related violence near schools substantially affects interstate commerce through its impact on education, workforce productivity, and the national economy. The dissent contended that the majority's approach was inconsistent with the Court's post-New Deal Commerce Clause precedents and improperly limited Congress's rational basis for finding a commercial nexus.
Key Quotes
“We start with first principles. The Constitution creates a Federal Government of enumerated powers.”
“Under the theories that the Government presents... 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.”
“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.”
Impact and Legacy
Lopez revived the notion of federalism-based limits on Commerce Clause power after decades of judicial deference. The three-category framework became the standard analytical tool for Commerce Clause questions. The decision emboldened further federalism challenges, leading to Morrison and NFIB v. Sebelius, and reinvigorated debate about the proper scope of federal power.
Exam Relevance
Lopez is one of the most frequently tested Commerce Clause cases. Exam questions routinely ask students to apply the three-category framework to new statutes, often requiring them to distinguish between economic and noneconomic activity. Students should be prepared to compare Lopez with Wickard and Raich to explain when aggregation applies.
Study Tips

- Understand the economic/noneconomic activity distinction and why it matters for the aggregation principle.
- Compare the majority's reasoning with the dissent's argument about cumulative effects.
- Be prepared to explain how Lopez changed the trajectory of Commerce Clause doctrine after decades of expansion.

More Constitutional Law Dissents
United States v. Morrison
529 U.S. 598 (2000) (2000)
Justice Souter, joined by Justices Stevens, Ginsburg, and Breyer, dissented, arguing that the majority's economic/noneconomic distinction was unworkable and that Congress's extensive factual findings of substantial effects on interstate commerce should have been given deference. The dissent contended that the majority was returning to the pre-New Deal era of judicial second-guessing of congressional economic judgments.
Gonzales v. Raich
545 U.S. 1 (2005) (2005)
Justice O'Connor, joined by Chief Justice Rehnquist and Justice Thomas, dissented, arguing that the majority's reasoning effectively returned to a pre-Lopez framework with no meaningful limits on Commerce Clause power. O'Connor contended that if homegrown marijuana for personal medical use is economic activity subject to aggregation, then it is difficult to imagine any activity that Congress cannot regulate.
National Federation of Independent Business v. Sebelius
567 U.S. 519 (2012) (2012)
The joint dissent of Justices Scalia, Kennedy, Thomas, and Alito would have struck down the entire ACA, arguing that the individual mandate was neither a valid exercise of the commerce power nor the taxing power, and that it was not severable from the rest of the Act. Justice Ginsburg, joined by Justices Sotomayor, Breyer, and Kagan, concurred in the judgment on the mandate but dissented on the Commerce Clause analysis, arguing the mandate was a valid exercise of the commerce power.
Lochner v. New York
198 U.S. 45 (1905) (1905)
Justice Holmes wrote a famous dissent arguing that the Fourteenth Amendment does not enact Herbert Spencer's Social Statics and that the Constitution permits states to regulate economic matters as long as a reasonable person could regard the law as a rational response to a perceived problem. Justice Harlan also dissented, arguing the evidence supported the legislature's judgment that bakery work posed genuine health risks.
West Coast Hotel Co. v. Parrish
300 U.S. 379 (1937) (1937)
Justice Sutherland, joined by Justices Van Devanter, McReynolds, and Butler, dissented, maintaining that the minimum wage law unconstitutionally impaired the freedom of contract and that the meaning of the Constitution does not change with the shifting of economic winds.
Griswold v. Connecticut
381 U.S. 479 (1965) (1965)
Justices Black and Stewart dissented separately. Both argued that while the Connecticut law was foolish, there was no general constitutional right to privacy. Justice Black argued that the Court was engaging in the same substantive due process analysis it had properly rejected in repudiating Lochner, substituting its own values for those of the legislature.
