Working Through a Problem

A commerce-power problem on an exam seldom announces which doctrine it is testing. It presents a federal statute, a challenger who says Congress lacked the power to enact it, and facts about conduct that may or may not touch a national market. The earlier sections of this chapter supplied the separate tools, and the work here is to run them in an order that reaches the answer efficiently. The order matters because each question either ends the analysis or narrows what is left. A statute that regulates the use of a channel of interstate commerce needs no argument about aggregate effects, and the considerations that govern the third category come into play only after the first two categories have been ruled out.¹ A statute that compels entry into a market fails before any category is consulted, because Congress may not justify federal regulation by pointing to the effect of inaction on commerce.²

The sequence also tracks the two concerns that the doctrine balances. Congress has to be able to regulate a genuinely national market effectively, which is why a local rule that a market regulation depends on stays within federal reach. The States keep the general police power, which is why a subject connected to commerce only through a chain of downstream costs stays with them, since a reading of the clause with no such limit would hand Congress the police power the Constitution withholds.³ Each question in the sequence is a marker that lets a court enforce that boundary without second-guessing ordinary economic regulation. A channel, a thing in commerce, an economic activity, and a place within a comprehensive scheme all point toward federal power, while noneconomic conduct that stands alone and reaches commerce only through an attenuated chain points toward the States.

Exam Analysis Steps

Because each question either ends the analysis or narrows the next one, the problem is best run in a fixed order, with the easy and decisive questions first. The steps are these:

Identify what the statute actually regulates, meaning the conduct or thing its operative text reaches, and set aside the harm Congress hoped to prevent by regulating it.
Ask whether the statute regulates something the person is already doing in a market or compels people to enter a market by buying a product, and conclude that the commerce power does not reach a statute that compels entry.
Ask whether the statute regulates the use of a channel of interstate commerce, or protects an instrumentality of commerce or a person or thing in commerce, and if it does, stop, because no showing about aggregate effects is needed.
If neither of those categories fits, treat the statute as resting on substantial effects, and ask whether the regulated activity is itself economic or is an essential part of a comprehensive scheme regulating an interstate market in the same commodity.
If the activity is economic or sits inside such a scheme, aggregate the class of similar activity and ask only whether Congress had a rational basis for finding a substantial effect on interstate commerce.
If the activity is noneconomic and the statute stands alone, run the remaining considerations by asking whether the statute has a jurisdictional element, whether findings explain an effect that is not obvious, and whether the chain from the activity to commerce is short or attenuated.
State the conclusion together with the weakest link in it, because results in the substantial-effects category are contestable.

Steps two and four carry the most weight, and each is easy to skip. The activity question comes before the categories because the power to regulate commerce presupposes commercial activity to regulate, so a statute that compels a purchase fails however the aggregate effect of declining to buy is counted.⁴ The fourth step offers two routes to the same destination. An activity that is itself economic can be aggregated with all similar activity, and a local activity that is not itself commercial can still be reached when leaving it unregulated would undercut a regulation of the interstate market in the same commodity.⁵ Review at step five is deferential, because the Court asks only whether a rational basis exists for concluding that the class, in the aggregate, substantially affects interstate commerce.⁶ Review at step six is less so, since the boundary between national and local power remains a question for the courts, and findings by themselves do not settle it.⁷

Three decided patterns anchor the method, and recognizing which one a problem resembles is often faster than building the analysis from the ground up. Each pattern ends at a different step of the checklist, which is the reason to learn them as a set:

A single-subject criminal ban on noneconomic local conduct, with no jurisdictional element and a link to commerce that runs only through downstream costs, follows United States v. Lopez, and it fails under the substantial-effects category.⁸
A comprehensive scheme regulating an interstate market in a fungible commodity follows Gonzales v. Raich, and it reaches even noncommercial local activity in that commodity when exempting the activity would undercut the scheme.⁹
A statute that compels people to buy a product or otherwise enter a market follows National Federation of Independent Business v. Sebelius, and it falls outside the commerce power because the failure to buy or sell is not commercial activity.¹⁰

The three differ in the fact on which each turns. In Lopez the decisive fact was that nothing economic stood between the regulated conduct and the market, so aggregation had nothing to count.¹¹ In Raich the regulated commodity had an established interstate market and the local ban protected a regulation of it, so conduct of the same kind, growing or possessing something at home, came out the other way because it belonged to a comprehensive scheme and not to a stand-alone ban.¹² NFIB stops earlier than either, at the activity question, and never reaches the categories or the considerations. The other two cases ask how much a person's existing activity matters to a market, while NFIB asks whether there is any activity to measure.

Hypothetical Illustration

A federal statute regulates the interstate market in a fungible grain additive through three provisions. The first bans shipping unlicensed additive across state lines. The second bans possessing unlicensed additive anywhere, including in a home workshop. The third requires every adult to buy a small quantity of licensed additive each year to keep licensed producers' prices stable. A challenger attacks all three, and the checklist sends each to a different stopping point. The shipping ban regulates the use of an interstate route, so it is supported at step three, even though the plant that makes the additive sits in one State. A person who keeps a jar of additive in a workshop uses no route, so the possession ban reaches step four. The activity is not itself commercial, but the additive is fungible, an established interstate market exists, and the ban is part of a scheme regulating that market, so Congress could rationally conclude that exempting home stock would undercut the scheme, and the ban stands. The purchase requirement stops at step two, because it reaches adults who do nothing in the additive market and compels them to enter it.

One statute therefore yields two provisions that stand and one that falls, and the step at which each provision stopped explains why. The third provision never reached the categories at all, which is why asking the activity question first saves the most effort on a problem that contains a mandate.

Federal criminal statutes are the most common place the method is applied outside the headline cases. Congress has used the commerce power as the hook for many federal crimes, and it usually writes the connection to commerce into the offense itself.¹³ The words of that connection tell you which step does the work. The wire fraud statute requires the government to show that the wires used were in interstate commerce, which ties each prosecution to a use of an interstate route for communication, so the channels step supports it and no aggregation argument is needed.¹⁴ Statutes that require only that the conduct affect commerce rest on the third category instead, as with the Hobbs Act requirement that the robbery or extortion affect commerce, or the racketeering statute's alternative of an enterprise whose activities affect commerce, and the economic-character question returns with them.¹⁵ Courts have accepted a minimal connection to commerce under the racketeering element when the enterprise itself engages in economic activity, but a minimal connection does not suffice where all that remains is "violence qua violence."¹⁶ Local conduct can also be a federal crime when it belongs to a class of economic activity that Congress finds affects commerce, as in the sustained federal prosecution of local loan sharking.¹⁷

Environmental statutes show the method operating across a range of footing. In passing them Congress has relied primarily on the commerce power.¹⁸ The statutes that regulate products bought and sold in interstate commerce, such as pesticides, asbestos, and automobiles, stand on firm ground, because the regulated subject is a commodity or a commercial activity and the early steps of the method answer in the government's favor.¹⁹ The reasoning of Raich adds support even for localized or noncommercial applications of the major pollution statutes, since local activity inside a scheme regulating an interstate market can be reached when excluding it might undermine the regulation.²⁰ The Court's later decision on the insurance mandate shows that it continues to take limits on the commerce power seriously.²¹

Federal rules that regulate local land use, such as the Endangered Species Act and the wetlands protections of the Clean Water Act, stand on less certain footing.²² Land use has historically been the province of local government, which makes federal involvement look like an intrusion, and the link between commerce and a small seasonal wetland or the confined habitat of an endangered species is much less obvious than the link between pesticides and commerce.²³ In terms of the method, such a statute usually finds no support at step three, because it regulates no route, vehicle, or cargo, and it arrives at step four with a subject that is neither a commodity nor obviously economic. The reasoning in Raich rested on a fungible commodity that could be diverted into an interstate market, and a parcel of land cannot be diverted, so the government's argument tends to run through aggregating a class of economic land uses, while the challenger answers that the subject is traditionally local and the chain to commerce is remote.²⁴

Hypothetical Illustration

A federal statute bars filling any wetland without a permit. A developer fills a large wetland to build a shopping center that will draw customers and tenants from several States, and a homeowner fills a small seasonal pool on a residential lot to extend a lawn. The developer's activity is itself commercial, and the government can aggregate commercial development of wetlands as a class, so the economic-character question favors the statute. The homeowner's activity is noneconomic, the link from a lawn to a national market runs through a chain of ecological and economic consequences, and the statute is a land-use rule in an area long left to local government, so the challenger's attenuation argument has real force. The statute reads the same in both applications, and the facts the checklist asks about are what differ.

Whether the homeowner's application can be carved out depends on whether the wetland rule counts as an essential part of a larger regulation of economic activity, the same level-of-generality dispute that divided the Justices in Raich, together with the rule that a court may not excise individual applications of a valid scheme as trivial.²⁵ Because the footing is uncertain, results in this area are contestable. A strong answer states the best argument on each side and identifies the fact that would move the outcome, such as whether the regulated land use is itself commercial development.

The last application tests the method against a tempting shortcut. When a fact pattern describes a broad federal crime accompanied by detailed congressional findings, the findings invite the conclusion that the statute must stand. The method treats findings as one input at step six, and the next illustration shows what happens to a statute that has nothing else behind it.

Hypothetical Illustration

Congress makes it a federal crime to commit any assault causing serious bodily injury anywhere in the country. The statute has no jurisdictional element, but committee reports find that assaults lower productivity, raise medical costs, and deter travel to areas perceived as unsafe. A defendant charged with assaulting a neighbor in a backyard moves to dismiss. The statute regulates assault as such, so step one identifies noneconomic criminal conduct. Step two finds no compelled purchase, and step three finds no channel, vehicle, person, or thing in commerce, because the statute attaches to assault wherever it occurs. Step four finds no comprehensive scheme regulating an interstate market, and at step six the statute has no element and its findings reach commerce only through a chain of costs, so the motion should succeed. Change one fact: the statute punishes only a person who crosses a state line intending to commit the assault and then does so. The statute now picks out the use of a route, step three supports it, and the findings are unnecessary.

The broad version fails for the reasons given in United States v. Morrison. There the Court found that the regulated violence was not economic activity, that the remedy had no jurisdictional element, and that the link to commerce was attenuated, and it treated the findings as weakened because they relied on reasoning that would let Congress regulate virtually any activity.²⁶ The existence of findings is not sufficient, by itself, to sustain Commerce Clause legislation, because whether an activity affects commerce enough to come under the power is ultimately a judicial question.²⁷ The twin statute survives because it operates on a different object. The regulation and punishment of intrastate violence that is not directed at the instrumentalities, channels, or goods involved in interstate commerce has long been the province of the States, so Congress reaches violence by aiming a statute at one of those routes.²⁸

On an exam, the usual error is to apply the four considerations from Lopez to every statute. Those considerations belong to the substantial-effects category, so a channels statute or a statute protecting a thing in commerce is resolved at step three without them.²⁹ The opposite error is to stop at step three, find no channel and no thing in commerce, and declare a local activity beyond federal reach, since economic activity and local activity inside a comprehensive scheme remain reachable at step four.³⁰ A complete answer also names the point at which reasonable judges disagree, whether that is the line between economic and noneconomic activity, the level of generality at which the class is defined, or the length of a causal chain.
