Homegrown Wheat, Machine Guns, and the Commerce Clause Today
When the Supreme Court struck down, as unconstitutional, the Gun-Free 
School Zone Act of 1990, 18 U.S.C. § 922(q)(1)(a), and 18 U.S.C. 
§ 13981, which provided a civil remedy to victims of 
gender-motivated violence, some experts expected an `enumerated powers 
doctrine' rescue as the Court struggled with how much power Congress 
should have when legislating using the Commerce Clause. Recent cases 
suggest there will be no rescue.
 
by Thomas J. Coaty
Observers of the U.S. Supreme Court sat dumbfounded, trying to 
comprehend what they had just heard. Chief Justice William Rehnquist had 
delivered the Court's opinion in United States v. Lopez1 on the constitutionality of the Gun-Free School 
Zones Act of 19902 and declared the law 
unconstitutional, stating:
"The Act neither regulates a commercial activity nor contains a 
requirement that the possession be connected in any way to interstate 
commerce. We hold that the Act exceeds the authority of Congress `[t]o 
regulate Commerce … among the several States …' U.S. Const., 
Art. I, § 8, cl. 3."3
Lawyers immediately thought of Wickerd4 and the pain it had caused first-year law school 
students studying constitutional law. Initially taught that citizens 
enjoyed limited government because of enumerated powers, law students 
were instructed to look no further than Article I, section 8 to see the 
specific powers possessed by Congress5 or to 
read James Madison who sought, through the Constitution, to limit the 
federal government's control by giving it "few and definite"6 powers. Law students were reminded that the 
Commerce Clause was a selling point for dispensing with the Articles of 
Confederation and adopting the Constitution because of the "need for 
commercial regulation at the national level."7 Such commercial regulation was desired to stop 
self-serving state regulation and to treat each state equally.8 Finally, the students' lesson concluded with the 
topic of power sharing - or what political theorists called "separation 
of powers," which was present not just at the federal level, ensuring 
that one branch did not dominate over another,9 but also was present between the individual states 
and the federal government10 (federalism 
and comity), again guaranteeing that the federal government would not 
dominate over the citizens.

Most law students understood the enumerated powers doctrine. But with 
the Supreme Court's interpretation of the Commerce Clause, the entire 
meaning of enumerated powers had changed.11 
Instead of interpreting "commerce among the states" as referring to a 
buyer and a seller across state lines or economic activity in more than 
one state, the Court elected to define commerce, beginning in 1937, as 
the "interconnected nature of the national economy."12 Thus, anything could be regulated by Congress, 
including poor farmer Wickerd's homegrown wheat that never left the 
farm, as long as it was interconnected with the national economy.13
Lopez, however, had just trumped Wickerd. The 
Supreme Court in Lopez reasoned that because the Gun-Free 
School Zones Act of 1990 was a criminal statute by its terms, it had 
nothing to do with "commerce," and because the Act had contained "no 
jurisdictional element which could ensure, by a case-by-case basis, that 
the firearm in question affected interstate commerce," the law was 
unconstitutional.14 For only the second 
time since the New Deal, the U.S. Supreme Court had struck down a 
federal law based on a lack of enumerated power.15
This article briefly discusses 18 U.S.C. § 922(o) (possession of 
a machine gun) and its analysis with Lopez and how proponents 
of using the enumerated powers doctrine to limit Congress's power 
ultimately were disappointed. This article also reviews how the federal 
court system analyzes legislation based on the Commerce Clause and pays 
specific attention to how Justice Samuel Alito, the newest member of the 
Supreme Court, determined constitutionality while sitting on the Third 
Circuit Court of Appeals. Finally, this article touches on what the 
future may bring for federal criminal legislation based on recent cases 
interpreting the Commerce Clause.
Magistrate Crocker Instructs the Congress
In the Western District of Wisconsin a defendant, in United 
States v. Kenney,16 had been charged 
with a federal gun violation, that is, he was charged with the "unlawful 
possession of a machine gun."17 According 
to the Court's holding in the electrically charged Lopez, 
however, possession of a machine gun had nothing to do with commerce nor 
did that same gun possession substantially affect interstate commerce. 
Based on this interpretation, the law outlawing machine gun possession 
could be struck down.
Help arrived from the Southern District of Mississippi, where Chief 
Judge William H. Barbour Jr. held in United States v. 
Bownds18 that the same machine gun 
possession law about to be argued in Wisconsin was unconstitutional in 
his court.19 Judge Barbour began his 
analysis with Wickerd and the homegrown wheat; he conceded, 
"Congress can regulate an individual's activity if that activity `exerts 
a substantial economic effect on interstate commerce' regardless of 
whether that individual's effect is direct or indirect."20 Judge Barbour, however, cautioned Congress about 
its limited power to regulate through the Commerce Clause, which was not 
limitless, and stated:
"This Court is concerned with the increasing federalization of crime 
by Congress, when such federalization occurs in apparent disregard of 
the Tenth Amendment mandate that rights not delegated to the federal 
government be reserved to the States."21
On Aug. 4, 1995, Federal Magistrate Stephen L. Crocker held that 18 
U.S.C. § 922(o) (possession of a machine gun) was 
unconstitutional. The magistrate said that the federal courts were not 
"apologists" for Congress and that the "Courts cannot and should not do 
Congress's work for it."22 Magistrate 
Crocker spelled out specifically what Congress should do to correct this 
law.
"Congress easily could have: included as an element of the crime that 
the possession or transfer have some effect on interstate commerce; 
provided a paragraph or two of legislative findings or intent; or 
perhaps even just incorporated by reference the legislative histories of 
prior gun control bills such as the Gun Control Act or the Firearm 
Owners' Protection Act. But Congress did not do any of these things.
"Absent some legislative history, how does Congress justify the 
current criminalization of the intrastate use of a machine gun that 
could well have been manufactured in the same state in which it is 
possessed? Home conversion of semi automatic firearms into fully 
automatic firearms is alarmingly easy and common.
"What nexus do such machine guns have to interstate commerce?"23
Prophetically, Magistrate Crocker saw the danger in allowing 
Congress, through the Commerce Clause, to outlaw the mere possession of 
an item when there is no nexus to interstate commerce.24 That recommendation was then forwarded to 
Barbara B. Crabb, chief judge of the federal district court for the 
Western District of Wisconsin.
Judge Crabb disagreed with the magistrate's recommendation and 
declared that the machine gun possession law was constitutional. Her 
reasoning was sound: although she and Magistrate Crocker both believed 
that the federal government could regulate machine guns, Magistrate 
Crocker believed that the federal government had not provided a nexus, 
and Judge Crabb believed a nexus was not needed. She stated that machine 
guns were "things in commerce" and therefore could be regulated. 
Furthermore, citing United States v. Perez,25 Judge Crabb said that Congress did not have to 
make "particularized findings in order to legislate" and, borrowing from 
Lopez, stated "Congress normally is not required to make formal 
findings as to the substantial burdens that an activity has on 
interstate commerce."26 Because Judge Crabb 
ruled that Congress did have the authority under the Commerce Clause to 
make the possession of a machine gun illegal, the defendant in 
Kenney pleaded to the charge with the hope of attacking the 
constitutionality at the appellate level.
On Feb. 5, 1996, Kenney was appealed to the U.S. Court of 
Appeals for the Seventh Circuit. The same argument that was advanced 
before Magistrate Crocker and Chief Judge Crabb - that Congress lacked 
the authority to outlaw mere possession of a machine gun because the law 
neither regulates a commercial activity nor contains a requirement that 
the possession be connected in any way to interstate commerce 
- now was heard in Chicago.27
On July 30, 1996, virtually a year to the day after Magistrate 
Crocker found 18 U.S.C. § 922(o) to be unconstitutional, the 
Seventh Circuit appellate court handed down its decision.28 The court started its determination with the 
standard of review: "in Commerce Clause cases the review is narrow and 
deferential."29 The court also cited the 
famous Hodel standard of review, which states, "[t]his power is 
`complete in itself, may be exercised to its utmost extent, and 
acknowledges no limitations other than are prescribed in the 
constitution.'"30 The Seventh Circuit then 
cited United States v. Darby31 
when it declared 18 U.S.C. § 922(o) (possession of a machine gun) 
constitutional and reasoned:
"The motive and purpose of a regulation of interstate commerce are 
matters for the legislative judgment upon the exercise of which the 
Constitution places no restriction and over which the courts are given 
no control."32
It appeared the Seventh Circuit was not swayed by James Madison and 
the Federalist Papers, the enumerated powers doctrine, or the holding in 
Lopez. The Seventh Circuit had just suggested that whenever 
Congress used the Commerce Clause, the court should virtually acquiesce. 
Furthermore, the court instructed that Lopez was meant to stop 
the outer reaches of congressional power, not roll back what has been 
the jurisprudence in Commerce Clause cases since the late 1930s. It was 
because the Gun-Free School Zones Act had a distance requirement (1,000 
feet from a school) that it had no substantial effect on interstate 
commerce, "whether taken as a single act or in the aggregate effect of 
all acts," and this made the law unconstitutional.33 Logically, therefore, because the federal 
statute against the possession of a machine gun had no area or zone 
requirement it was constitutional. Constitutional because without an 
area or zone requirement, the possession of a machine gun substantially 
affected interstate commerce and thus could be outlawed by Congress.
As the Seventh Circuit was ruling that Congress did have the power to 
regulate possession of a machine gun through the Commerce Clause, the 
U.S. Court of Appeals for the Third Circuit was hearing the same 
constitutional argument about Congressional power and machine gun 
possession in United States v. Rybar.34 Like the Seventh Circuit in Kenney, the 
Third Circuit also declared the statute constitutional and added 
ominously that, "Lopez has `raised many false hopes,' [for 
defendants] and that challenges based on Lopez `almost 
invariably' fail."35
The Third and Seventh Circuits had used the same analysis, pioneered 
in 1971 in United States v. Perez,36 when ruling as to whether Congress had violated 
the Constitution in its use of the Commerce Clause when making 
legislation. The Perez Court instructed that Congress may 
regulate three broad categories of activity: "(1) the use of the 
channels of interstate commerce; (2) the instrumentalities of interstate 
commerce, or persons or things in interstate commerce, even though the 
threat may come only from intrastate activities; and (3) those 
activities that substantially affect interstate commerce."
The Third Circuit then analyzed the machine gun statute under the 
third prong and followed the Kenney analysis,37 stating Congress can "regulate singular 
instances of intrastate activity when the cumulative effect has a 
substantial effect on interstate commerce."38 Therefore, if Congress can regulate homegrown 
wheat because it substantially affects interstate commerce, it can 
regulate possession of a machine gun. Wickerd had returned.
Judge Alito Takes No Prisoners
Just when it seemed the issue had been settled, on Dec. 30, 1996, 
Third Circuit appellate judge Samuel Alito looked at the legal landscape 
and wrote, in essence, "nope." In the first two sentences of his dissent 
in Rybar, Judge Alito made it clear he was not happy about the 
federal appellate courts acquiescing to Congress's regulating of 
intrastate activities. Indeed, he was taking no prisoners when he 
rhetorically asked:
"Was United States v. Lopez a constitutional freak? Or did 
it signify that the Commerce Clause still imposes some meaningful limits 
on congressional power?"39
Judge Alito conceded that his "sister circuits" had ruled contrary to 
him on the constitutionality of the possession of a machine gun,40 and yet Judge Alito demonstrated that those same 
circuits could not agree on what prong of the Perez test should 
apply. Judge Alito pointed out that some circuits upheld the 
constitutionality because they claimed that machine guns fell under the 
first Perez prong: the use of the channels of interstate 
commerce. These circuits argued that because Congress could regulate 
lottery tickets,41 adulterated food,42 and the interstate transportation of women for 
immoral purposes,43 then logically, machine 
guns also could be regulated. Judge Alito agreed and conceded that 
government is "free to exclude from commerce any article the government 
deems injurious to the public health, morals or welfare, even though the 
state has not sought to regulate that use."44 Judge Alito objected to the confusion between an 
illegal transfer of a weapon and an interstate 
transfer of that same weapon.45 He believed 
that if the courts wished to find intrastate possession of a machine gun 
illegal, they must use the third prong of the Perez analysis: 
regulation of activities that substantially affect interstate 
commerce.
Judge Alito criticized other circuits for finding the machine gun 
statute constitutional by their use of the second prong of the 
Perez analysis. The Lopez court had cited two statutes 
that would be constitutional under the Perez second prong: 18 
U.S.C. § 32, which made it a crime to damage or destroy aircraft 
that was used in interstate commerce, and 18 U.S.C. § 659, which 
made it illegal to steal from interstate shipments.46 Using Lopez as his basis for reasoning, 
Judge Alito believed that the U.S. Supreme Court defined 
"instrumentalities" of interstate commerce as "the means of conveying 
people and goods across state lines, such as airplanes and 
trains."47 Additionally, Judge Alito 
believed Congressional power can be extended to protect people or goods 
traveling interstate by outlawing theft or setting rates.48 Thus, Judge Alito's dissent concerning placing 
the statute in the Perez second category centered on 
definition:
"18 U.S.C. § 922(o) (the machine gun law) would fall within this 
second Lopez category if Congress had banned the intrastate 
possession of machine guns in order to prevent them from being used to 
damage vehicles traveling interstate, to carry out robberies of goods 
moving in interstate commerce, or to threaten or harm interstate 
travelers."49 Because there is no such 
language in the statute, Judge Alito dissented on its 
constitutionality.
Judge Alito's final argument concerned what he called the "crux of 
this case:"50 "[T]he majority argues in 
effect that the private, purely intrastate possession of machine guns 
has a substantial effect on the interstate machine gun market."51
Judge Alito argued that if one accepts the majority's argument, 
anything has an effect on the national economy and, therefore, Congress 
can regulate anything. Such a theory ignores the reasoning of the 
Lopez court, which began its opinion on "first 
principles."52 Those principles give the 
federal government enumerated powers and constitutionally mandated 
divisions of authority (between the federal government and the states), 
which "was adopted by the Framers to ensure protection of our 
fundamental liberties."
Moreover, Judge Alito pointedly asked the majority, how is the 
possession of a machine gun inherently more "economic" or more 
"commercial" than possession of other firearms?53 Or, is the possession of a firearm in a school 
zone less "economical" or "commercial" than possession elsewhere - say, 
on one's own property?54 Thus, the future 
Supreme Court justice believed the Lopez decision suggested 
that the mere possession of a machine gun, without more, was not 
"economic" or "commercial" and therefore could not be regulated by 
Congress through the Commerce Clause. This is in direct contrast to 
Farmer Wickerd and his homegrown wheat, which although intrastate, is 
clearly "economic" or "commercial" and thus could be regulated by 
Congress in its use of the Commerce Clause.55
More thunder was created in Commerce Clause jurisprudence, when the 
Supreme Court in United States v. Morrison struck down 42 
U.S.C. § 13981, which provided a civil remedy to victims of 
gender-motivated violence.56 The Court 
again, when analyzing federal legislation involving the Commerce Clause, 
used the "third prong of the Perez test"57 and stated that it had rejected the government's 
argument that "costs of crime" and "national productivity" were the 
substantial effect on interstate commerce.58 The Court observed that by using this argument, 
Congress "could regulate any activity as it was related to economic 
productivity of the individual."59 The 
federal government could regulate family law, criminal law, or 
education, areas in which "States historically have been 
sovereign."60 The Court finished with a 
flurry by warning that Congress may "not regulate non economic, violent 
criminal conduct based solely on that conduct's aggregate effect on 
interstate commerce."61 Morrison 
was the heir to Lopez. It appeared that the Rehnquist Court was 
returning limited government through enumerated powers to the 
people.
Homemade Machine Guns on Interstate Commerce
Then it happened. Out of California and the 9th Circuit came the 
ultimate case regarding the possession of a machine gun. In United 
States v. Stewart the court pondered "[w]hether 
Congress can, under its Commerce Clause power, prohibit the mere 
possession of homemade machine guns?"62 In 
its analysis, the 9th Circuit appellate court quickly pushed aside 
United States v. Rambo,63 which 
had held that an illegal possession must have proceeded with an illegal 
transfer.64 The illegal transfer had a 
substantial effect on interstate commerce and was thus constitutional. 
The 9th Circuit appellate court noted that the defendant in 
Stewart made his machine gun in his basement. The appellate 
court then discussed the district court opinion, which found the machine 
gun statute constitutional because there had to be some part, even in 
this homemade machine gun, that had to have been purchased - and there 
had been. Because a part had been purchased, the lower court reasoned, 
it had to come from somewhere, and that somewhere meant it substantially 
affected interstate commerce.65 The 
appellate court sniffed: "This cannot mean that everything is 
subject to federal regulation under the Commerce Clause, else that 
constitutional limitation would be entirely meaningless."66 Indeed, using Lopez as a hammer, the 
Stewart court drove home the nail that Congressional power has 
limits and to ignore those limits "obliterates the distinction between 
what is national and what is local," the result of which would create a 
"completely centralized government."67 The 
9th Circuit appellate court finished by saying that the possession of a 
homemade machine gun was not illegal because it did not have a 
substantial effect on interstate commerce.68
Supporters of limited government anticipated that once the United 
States appealed, Chief Justice Rehnquist could ignite a Commerce Clause 
jurisprudence rescue for the enumerated powers doctrine. Armed with 
Lopez, and fortified with Morrison, Stewart 
would make American legal history.
Homemade Machine Guns and Medicinal Marijuana
In its writ of certiorari, the U.S. government in Stewart 
not only maintained that 18 U.S.C. § 922(o) had been upheld in 
every federal circuit court69 but also 
argued that pursuant to Wickerd, "even non-commercial activity 
occurring within a regulated market is subject to Congress' commerce 
power."70 In its brief, the government 
asked that the Stewart machine gun case be held until the U.S. 
Supreme Court could decide Ashcroft v. Raich. In that case, the 
issue was whether the Controlled Substances Act, 21 U.S.C. § 801, 
exceeded the Commerce Clause when dealing with intrastate cultivation 
and possession of marijuana for purported personal "medicinal" use or 
the distribution of marijuana without charge for such use. The brief 
went on to suggest that because both the Stewart and 
Ashcroft cases deal with commodities that typically are 
acquired through commercial transactions, it would "shed significant 
light" on this case when the Court decided Ashcroft.71 The Supreme Court agreed and prepared to rule on 
Ashcroft first.
Conclusion
Supporters of limited government read Ashcroft v. Raich, now 
called Gonzales v. Raich, in stunned silence. They 
learned that the U.S. Supreme Court had held that Lopez and 
Morrison had been read too broadly inside the concept of 
"modern day Commerce Clause jurisprudence" when it upheld the 
constitutionality of the Controlled Substance Act, 21 U.S.C. § 801. 
Congress could outlaw medical marijuana, even though a 
California law expressly allowed it.72 More 
to the point, the Court said that this issue of medicinal marijuana was 
analogous to homegrown wheat; the possession of marijuana for medical 
purposes was an economic intrastate activity that substantially affected 
interstate commerce, and thus it could be regulated.
The U.S. Supreme Court simply ordered the 9th Circuit to rehear 
Stewart consistent with Gonzales and determined that a 
homemade machine gun was an intrastate economic activity that 
substantially affected interstate commerce, and thus it could be 
regulated.73 If the U.S. Supreme Court could regulate 
homegrown wheat, it could regulate homegrown machine guns.
In conclusion it appears that the "enumerated powers doctrine" 
displayed in Lopez will be more aggressively argued on 
constitutional exams in law school than it will be argued in the federal 
court system. The Lopez decision was simply a shot fired across 
Congress's bow warning that legislators must be circumspect in crafting 
legislation. For Wisconsin lawyers, United States v. 
Lopez does little more than suggest that Congress will no longer 
draft criminal statutes with an area requirement (for example, within 
1,000 feet of a school) to trigger enforcement. In a larger sense, 
Lopez is a primer for the practitioner of our shared 
constitutional and national history.
