Substantial Effect on Interstate Commerce
This is the workhorse of the commerce power, and it has a clean structure once you see it.
7. Substantial Effect on Interstate Commerce
The Commerce Clause authorizes regulation of economic and noneconomic activity with a “substantial effect” on interstate commerce, including activity that meets that threshold when aggregated with others doing the same thing.
- To be within Congress’s power under the Commerce Clause, a federal law must:
- Regulate the channels of interstate commerce;
- Regulate the instrumentalities of interstate commerce and persons and things in interstate commerce; or
- Regulate activities that have a substantial effect on interstate commerce. United States v. Lopez, 514 U.S. 549 (1995).
- When Congress attempts to regulate intrastate activity under the third prong above, the Court will uphold the regulation if it is of economic or commercial activity and the court can conceive of a rational basis on which Congress could conclude that the activity in aggregate substantially affects interstate commerce. Gonzales v. Raich, 545 U.S. 1 (2005).
- When Congress attempts to regulate intrastate activity under the third prong, and the regulated intrastate activity is not commercial or economic, the Court generally will not aggregate the effects and the regulation will be upheld only if Congress can show a direct substantial economic effect on interstate commerce, which it generally will not be able to do. E.g.:
- United States v. Lopez, 514 U.S. 549 (1995) (federal statute barring possession of a gun in a school zone is invalid);
- United States v. Morrison, 529 U.S. 598 (2000) (federal civil remedy for victims of gender-motivated violence is invalid).
- The classic aggregation case is the Court’s holding that Congress can control a farmer’s production of wheat for home consumption because the cumulative effect of many instances of such production could be felt on the supply and demand of the interstate commodity market. Wickard v. Filburn, 317 U.S. 111 (1942).
A federal law is within the Commerce Clause if it regulates the channels, the instrumentalities (and persons and things in commerce), or activities with a substantial effect on interstate commerce. On that third prong, everything turns on one switch: is the intrastate activity economic or noneconomic?
This is the workhorse of the commerce power, and it has a clean structure once you see it. A federal law is within the Commerce Clause if it does any of three things.
- 1It regulates the channels of interstate commerce, the highways, waterways, and pathways goods and people move through.
- 2It regulates the instrumentalities of interstate commerce, and the persons and things in interstate commerce, the trucks, trains, and the goods and people moving across state lines.
- 3It regulates activities that have a substantial effect on interstate commerce.
The first two prongs are rarely the fight. The third prong is where almost every hard question lives, and it splits in a way you have to get right. When Congress reaches a purely intrastate activity under the third prong, ask one question first: is the regulated activity economic or commercial, or is it not? If the activity is economic or commercial, the Court will uphold the regulation so long as it can conceive of a rational basis on which Congress could conclude that the activity, in the aggregate, substantially affects interstate commerce. That is a generous standard, and aggregation is allowed: you add up all the instances of the activity across the country. The classic case is a farmer growing wheat for his own consumption, which Congress can reach because the cumulative effect of many farmers doing the same thing moves the national wheat market.
But flip the activity. When the regulated intrastate activity is not commercial or economic, the Court generally will not aggregate the effects. The regulation will be upheld only if Congress can show a direct substantial economic effect on interstate commerce, which it generally will not be able to do. That is why a federal ban on possessing a gun in a school zone, and a federal civil remedy for victims of gender-motivated violence, were both invalid: the underlying activity was noneconomic, so the aggregation trick was off the table, and there was no direct substantial economic effect. So the whole game on the third prong is the economic/noneconomic switch: economic activity gets the rational-basis-plus-aggregation treatment and almost always survives; noneconomic activity does not get aggregated and almost always fails.
Three prongs: channels, instrumentalities (plus persons/things in commerce), and substantial effect. The fight is almost always the third prong, and the third prong turns on one switch: is the intrastate activity economic or noneconomic? Economic: aggregate it, and a rational basis that the aggregate substantially affects commerce is enough, so it survives (the home-grown wheat case). Noneconomic: no aggregation, and Congress must show a direct substantial economic effect, which it generally cannot, so it fails (gun in a school zone; gender-motivated-violence remedy). The killer move: before you decide, label the activity economic or not. If an answer aggregates a noneconomic activity to uphold the law, eliminate it. If an answer demands a direct effect for an economic activity, eliminate it too.
Suppose a national legislature, to support the price of a farm commodity, limits how much of that commodity each farmer may grow, and applies the limit even to a farmer who grows a small amount purely for his own household use and never sells any of it. The farmer says his backyard crop is local and never enters interstate commerce, so Congress cannot reach it.
Now flip the activity. Suppose the legislature instead made it a federal crime simply to possess an object in a particular local place, conduct with nothing economic about it. Now there is no aggregation, and Congress would have to show a direct substantial economic effect on interstate commerce, which it generally cannot. That regulation falls.
An option that adds up the nationwide effects of a noneconomic intrastate activity to find a substantial effect on interstate commerce.
Aggregation is for economic or commercial activity. When the activity is noneconomic, the Court generally will not aggregate, and Congress must show a direct substantial economic effect it generally cannot.An option that misstates the standard for economic activity, demanding a direct substantial effect, or requiring Congress to prove rather than have a rational basis for the aggregate effect.
For economic activity, a rational basis that the aggregate substantially affects interstate commerce is enough; the direct-effect test is for noneconomic activity.An option keyed on the activity being local, small, or never itself crossing a state line.
Intrastate economic activity may be reached through its aggregate effect even though the single instance is local; locality alone does not defeat the third prong.A 'valid' option for an economic-activity regulation that points to the wrong prong (channels or instrumentalities) instead of the substantial-effect/aggregation rationale.
Name the prong and rationale that actually fit the facts; an economic intrastate activity is upheld under the substantial-effect prong by aggregation, not by a prong that does not apply.the stem has Congress reaching some local, intrastate activity and asks whether the commerce power supports it.
place the prong: channels, instrumentalities/persons-and-things, or substantial effect.
If it is the substantial-effect prong, immediately label the activity economic or noneconomic, because that label decides the case.
Economic or commercial: the Court aggregates and upholds on a rational basis that the aggregate substantially affects interstate commerce, so the law almost always stands under existing precedent.
Noneconomic: no aggregation, and the law stands only on a direct substantial economic effect, which Congress generally cannot show, so the law almost always falls.
Watch for an answer that quietly aggregates a noneconomic activity, or that demands a direct effect for an economic one; both invert the switch.
To stabilize the national market for a farm commodity, a national legislature capped the quantity of that commodity each grower could produce. The cap applied to a grower who raised a small amount of the commodity solely for his own household and sold none of it. The grower challenged the cap, arguing that his production was local, was never sold, and never itself entered interstate commerce.
Is the cap most likely a valid exercise of the commerce power as applied to the grower under existing precedent?
A national legislature made it a federal crime to possess a certain object while standing within a defined local area near a school. Possessing the object in that area was not a commercial or economic activity. Defending the law, the legislature argued that if every such possession across the country were added together, the total would substantially affect interstate commerce. A person charged under the law challenged Congress's authority to enact it.
Is the challenge to Congress's authority most likely to succeed under existing precedent?
A national legislature created a federal civil remedy allowing victims of a particular kind of violent assault to sue their attackers. The assault that the remedy addressed was not a commercial or economic activity. The legislature defended the remedy by adding up, across the whole country, the medical costs and lost productivity caused by such assaults and arguing that the total substantially affected interstate commerce. A defendant sued under the remedy challenged Congress's authority to create it.
Is the federal civil remedy most likely beyond Congress's commerce power under existing precedent?
A national legislature enacted a statute regulating the trucks, rail cars, and shipping containers used to carry goods from one state to another, setting safety standards for those vehicles and containers while they are in use moving goods across state lines. A carrier challenged the statute, arguing that Congress could not regulate equipment unless it could also prove a substantial effect on the national economy in the aggregate.
Is the statute most likely within Congress's commerce power under existing precedent?
A national legislature enacted a statute reaching a purely intrastate commercial activity, and the legislature relied on the theory that the activity, when combined with the same activity by many others, substantially affects interstate commerce. A business subject to the statute argued that because its own operations were modest and confined to a single state, the activity could not be aggregated and the statute had to be judged solely by its individual, direct effect on interstate commerce.
Is the business's argument that the activity may not be aggregated most likely to succeed under existing precedent?
