v.
DONALDO MORALES
KANSAS, PETITIONER
v.
GUADALUPE OCHOA-LARA
on writ of certiorari to the supreme court of
kansas
[March 3, 2020]
Justice Alito delivered the opinion of the
Court.
Kansas law makes it a crime to commit “identity
theft” or engage in fraud to obtain a benefit. Respondents—three
aliens who are not authorized to work in this country—were
convicted under these provisions for fraudulently using another
person’s Social Security number on state and federal
tax-withholding forms that they submitted when they obtained
employment. The Supreme Court of Kansas held that a provision of
the Immigration Reform and Control Act of 1986 (IRCA), 100Stat.
3359, expressly preempts the Kansas statutes at issue insofar as
they provide a basis for these prosecutions. We reject this reading
of the provision in question, as well as respondents’ alternative
arguments based on implied preemption. We therefore reverse.
I
A
The foundation of our laws on immigration and
naturalization is the Immigration and Nationality Act (INA),
66Stat. 163, as amended, 8 U. S. C. §1101
et seq., which sets out the “ ‘terms and
conditions of admission to the country and the subsequent treatment
of aliens lawfully in the country.’ ”
Chamber of
Commerce of United States of America v.
Whiting,
563 U.S.
582, 587 (2011). As initially enacted, the INA did not prohibit
the employment of illegal aliens, and this Court held that federal
law left room for the States to regulate in this field. See
De
Canas v.
Bica,
424 U.S.
351, 353 (1976).
With the enactment of IRCA, Congress took a
different approach. IRCA made it unlawful to hire an alien knowing
that he or she is unauthorized to work in the United States.
8 U. S. C. §§1324a(a)(1)(A), (h)(3). To enforce this
prohibition, IRCA requires employers to comply with a federal
employment verification system. §1324a(b). Using a federal
work-authorization form (I–9), employers “must attest” that they
have “verified” that an employee “is not an unauthorized alien” by
examining approved documents such as a United States passport or
alien registration card. §1324a(b)(1)(A); see also
§§1324a(b)(1)(B)–(D); 8 CFR §274a.2(a)(2) (2019) (establishing Form
I–9). This requirement applies to the hiring of any individual
regardless of citizenship or nationality. 8 U. S. C.
§1324a(b)(1). Employers who fail to comply may face civil and
criminal sanctions. See §§1324a(e)(4), (f ); 8 CFR §274 A. 10.
IRCA instructs employers to retain copies of their I–9 forms and
allows employers to make copies of the documents submitted by
employees to show their authorization to work. 8 U. S. C.
§§1324a(b)(3)–(4).
IRCA concomitantly imposes duties on all
employees, regardless of citizenship. No later than their first day
of employment, all employees must complete an I–9 and attest that
they fall into a category of persons who are authorized to work in
the United States. §1324a(b)(2); 8 CFR §274a.2(b)(1)(i)(A). In
addition, under penalty of perjury, every employee must provide
certain personal information—specifically: name, residence address,
birth date, Social Security number, e-mail address, and telephone
number. It is a federal crime for an employee to provide false
information on an I–9 or to use fraudulent documents to show
authorization to work. See 18 U. S. C. §§1028, 1546.
Federal law does not make it a crime for an alien to work without
authorization, and this Court has held that state laws
criminalizing such conduct are preempted.
Arizona v.
United States,
567 U.S.
387, 403–407 (2012). But if an alien works illegally, the
alien’s immigration status may be adversely affected. See 8
U. S. C. §§1255(c)(2), (8), 1227(a)(1)(C)(i).
While IRCA imposes these requirements on
employers and employees, it also limits the use of I–9 forms. A
provision entitled “Limitation on use of attestation form,”
§1324a(b)(5), provides that I–9 forms and “any information
contained in or appended to such form[s] may not be used for
purposes other than for enforcement of ” the INA or other
specified provisions of federal law, including those prohibiting
the making of a false statement in a federal mat- ter ( 18
U. S. C. §1001), identity theft (§1028),
immigration-document fraud (§1546), and perjury (§1621). In
addition, 8 U. S. C. §1324a(d)(2)(F) prohibits use of
“the employ- ment verification system” “for law enforcement
purposes,” apart from the enforcement of the aforementioned federal
statutes.
Although IRCA expressly regulates the use of
I–9’s and documents appended to that form, no provision of IRCA
directly addresses the use of other documents, such as federal and
state tax-withholding forms, that an employee may complete upon
beginning a new job. A federal regulation provides that all
employees must furnish their employers with a signed withholding
exemption certificate when they start a new job, but federal law
apparently does not require the discharge of an employee who fails
to do so. See 26 CFR §§31.3402(f )(2)–1, (5)–1 (2019).
Instead, the regulation provides that if an employee fails to
provide a signed W–4, the employer must treat the employee “as a
single person claiming no exemptions.” §31.3402(f )(2)–1(a).
The submission of a fraudulent W–4, however, is a federal crime. 26
U. S. C. §7205.
Kansas uses a tax-withholding form (K–4) that is
similar to the federal form. Kan. Stat. Ann. §79–3298 (2018 Cum.
Supp.); Kansas Dept. of Revenue, Notice 07–07: New K–4 Form for
State Withholding (Sept. 5, 2007), www.ortho
don.com/home/document/KS-WithholdingForm.pdf; Kansas Dept. of
Revenue, Kansas Withholding Form K–4, www.ks
revenue.org/k4info.html. Employees must attest to the veracity of
the information under penalty of perjury. Form K–4, Kansas
Employee’s Withholding Allowance Certificate (rev. Nov. 2018),
www.ksrevenue.org/pdf/k-4.pdf; Kan. Stat. Ann. §21–5903; see also
Kansas Dept. of Revenue, Tax Fraud Enforcement,
www.ksrevenue.org/taxfraud.html.
Finally, IRCA contains a provision that
expressly “preempt[s] any State or local law imposing civil or
criminal sanctions (other than through licensing and similar laws)
upon those who employ,
or recruit or refer for a fee for
employment, unauthorized aliens.” 8 U. S. C.
§1324a(h)(2) (emphasis added). This provision makes no mention of
state or local laws that impose criminal or civil sanctions on
employees or applicants for employment. See
ibid.
B
Like other States, Kansas has laws against
fraud, forgeries, and identity theft. These statutes apply to
citizens and aliens alike and are not limited to conduct that
occurs in connection with employment. The Kansas identity-theft
statute criminalizes the “using” of any “personal identifying
information” belonging to another person with the intent to
“[d]efraud that person, or anyone else, in order to receive any
benefit.” Kan. Stat. Ann. §21–6107(a)(1). “[P]ersonal identifying
information” includes, among other things, a person’s name, birth
date, driver’s license number, and Social Security number.
§21–6107(e)(2). Kansas courts have interpreted the statute to cover
the use of another person’s Social Security number to receive the
benefits of employment. See
State v.
Meza, 38 Kan.
App. 2d 245, 247–250, 165 P.3d 298, 301–302 (2007).
Kansas’s false-information statute criminalizes,
among other things, “making, generating, distributing or drawing” a
“written instrument” with knowledge that it “falsely states or
represents some material matter” and “with intent to defraud,
obstruct the detection of a theft or felony offense or induce
official action.” §21–5824.
The respondents in the three cases now before us
are aliens who are not authorized to work in this country but
nevertheless secured employment by using the identity of other
persons on the I–9 forms that they completed when they applied for
work. They also used these same false identities when they
completed their W–4’s and K–4’s. All three respondents were
convicted under one or both of the Kansas laws just mentioned for
fraudulently using another person’s Social Security number on
tax-withholding forms. We summarize the pertinent facts related to
these three prosecutions.
C
Ramiro Garcia. In August 2012, a local
patrol officer stopped Garcia for speeding and learned that Garcia
had been previously contacted by a financial crimes detective about
possible identity theft. App. 39–44, 89–91; 306 Kan. 1113, 1114,
401 P.3d 588, 590 (2017). Local authorities obtained the documents
that Garcia had completed when he began work at a restaurant, and a
joint state-federal investigation discovered that Garcia had used
another person’s Social Security number on his I–9, W–4, and K–4
forms. The State then charged Garcia with identity theft. The
complaint alleged that, when he began work at the restaurant, he
used another person’s Social Security number with the intent to
defraud and in order to receive a benefit. App. 9–10.
Donaldo Morales. A joint state-federal
investigation of Morales began after the Kansas Department of Labor
notified a Social Security agent that an employee at a local
restaurant was using a Social Security number that did not match
the identifying information in the department’s files. 306 Kan.
1100, 1101, 401 P.3d 155, 156 (2017); App. to Pet. for Cert. 73;
App. 124–125, 168–170. A federal agent contacted the restaurant and
learned that Morales had used another person’s Social Security
number on his I–9, W–4, and K–4 forms. The federal agent arrested
Morales, who then admitted that he had bought the Social Security
number from someone he met in a park. App. 171–172; 306 Kan., at
1101–1102, 401 P. 3d, at 156; App. to Pet. for Cert.73. This
information was turned over to state prosecutors, who charged
Morales with identity theft and making false information. App.
124–125; 306 Kan., at 1101, 401 P. 3d, at 156.
Guadalupe Ochoa-Lara. Ochoa-Lara came to
the attention of a joint state-federal task force after officers
learned that he had used a Social Security number issued to someone
else when he leased an apartment. 306 Kan. 1107, 1108–1109, 401
P.3d 159, 160–161 (2017). The individual to whom this number was
lawfully assigned advised the investigating officers that she had
no knowledge that another person was using her number, and she
later told authorities that income that she had not earned had been
reported under her number.
Id., at 1109, 401 P. 3d, at
160. After contacting the restaurant where Ochoa-Lara worked,
investigators determined that he had also used the same Social
Security number to complete his I–9 and W–4 forms.
Ibid. The
State charged Ochoa-Lara with identity theft and making false
information for using another’s Social Security number on those
documents.
D
In all three cases, respondents argued before
trial that IRCA preempted their prosecutions. They relied on 8
U. S. C. §1324a(b)(5), which, as noted, provides that I–9
forms and “any information contained in or appended to such form[s]
may not be used for purposes other than for enforcement of ”
the INA or other listed federal statutes. In response, the State
dismissed the charges that were based on I–9’s and agreed not to
rely on the I–9’s at trial. The State maintained, however, that
§1324a(b)(5) did not apply to the respondents’ use of false Social
Security numbers on the tax-withholding forms.
The trial courts allowed the State to proceed
with the charges based on those forms. The State entered the K–4’s
and W–4’s into evidence against Garcia and Morales, and Ochoa-Lara
stipulated to using a stolen Social Security number on a W–4. App.
109–110; 306 Kan., at 1108–1109, 401 P. 3d, at
160–161.[
1] Respondents were
convicted, and three separate panels of the Kansas Court of Appeals
affirmed their convictions.
A divided Kansas Supreme Court reversed,
concluding that “the plain and unambiguous language of 8
U. S. C. §1324a(b)(5)” expressly prohibits a State from
using “any information contained within [an] I–9 as the bas[i]s for
a state law identity theft prosecution of an alien who uses
another’s Social Security information in an I–9.” 306 Kan., at
1130–1131, 401 P.3d at 599 (emphasis deleted). The court added that
“[t]he fact that this information was included in the W–4 and K–4
did not alter the fact that it was also part of the I–9.”
Id., at 1131, 401 P. 3d, at 599. In deciding the appeal
on these grounds, the court appears to have embraced the
proposition that any fact to which an employee attests in an I–9 is
information that is “contained in” the I–9 and is thus subject to
the restrictions imposed by §1324a(b)(5), namely, that this fact
cannot be used by anyone for any purpose other than the few listed
in that provision. Nevertheless, the court suggested that its
holding did not sweep this broadly but was instead limited to the
prosecution of aliens for using a false identity to establish
“employment eligibility.”
Id., at 1126, 1131, 401
P. 3d, at 596, 600.
Justice Luckert concurred based on implied, not
express, preemption. In her view, IRCA occupies “the field” within
which the prosecutions at issue fell, namely, “the use of false
documents, including those using the identity of others, when an
unauthorized alien seeks employment.”
Id. at 1136, 401
P. 3d, at 602. Justice Luckert also opined that the Kansas
statutes, as applied in these cases, conflict with IRCA because
they “usur[p] federal enforcement discretion” regarding the
treatment of aliens who obtain employment even though they are
barred from doing so under federal law.
Ibid., 401
P. 3d, at 603.
Two members of the court, Justices Biles and
Stegall, dissented, and we granted review. 586 U. S. ___
(2019).
II
The Supremacy Clause provides that the
Constitution, federal statutes, and treaties constitute “the
supreme Law of the Land.” Art. VI, cl. 2. The Clause provides “a
rule of decision” for determining whether federal or state law
applies in a particular situation.
Armstrong v.
Exceptional Child Center, Inc., 575 U.S. 320, 324 (2015). If
federal law “imposes restrictions or confers rights on private
actors” and “a state law confers rights or imposes restrictions
that conflict with the federal law,” “the federal law takes
precedence and the state law is preempted.”
Murphy v.
National Collegiate Athletic Assn., 584 U. S. ___, ___
(2018) (slip op., at 22).
In all cases, the federal restrictions or rights
that are said to conflict with state law must stem from either the
Constitution itself or a valid statute enacted by Congress. “There
is no federal preemption
in vacuo,” without a constitutional
text, federal statute, or treaty made under the authority of the
United States.
Puerto Rico Dept. of Consumer Affairs v.
ISLA Petroleum Corp.,
485 U.S.
495, 503 (1988); see also
Whiting, 563 U. S., at
599 (preemption cannot be based on “a ‘freewheeling judicial
inquiry into whether a state statute is in tension with federal
objectives.’ ”) (citation omitted);
Virginia Uranium,
Inc. v.
Warren, 587 U. S. ___, ___ (2019) (lead
opinion of Gorsuch, J.) (slip op., at 3) (“Invoking some brooding
federal interest or appealing to a judicial policy preference” does
not show preemption).
In some cases, a federal statute may expressly
preempt state law. See
Pacific Gas & Elec. Co. v.
State Energy Resources Conservation and Development Comm’n,
461 U.S.
190, 203 (1983) (“It is well established that within
constitutional limits Congress may preempt state authority by so
stating in express terms.”). But it has long been established that
preemption may also occur by virtue of restrictions or rights that
are inferred from statutory law. See,
e.g.,
Osborn v.
Bank of United States, 9 Wheat. 738, 865 (1824) (rejecting
argument that a federal exemption from state regulation “not being
expressed, ought not to be implied by the Court”). And recent cases
have often held state laws to be impliedly preempted. See,
e.g.,
Arizona 567 U. S., at 400–408;
Kurns v.
Railroad Friction Products Corp.,
565 U.S.
625, 630–631 (2012);
PLIVA, Inc. v.
Mensing,
564 U.S.
604, 617–618 (2011).
In these cases, respondents do not contend that
the Kansas statutes under which they were convicted are preempted
in their entirety. Instead, they argue that these laws must yield
only insofar as they apply to an unauthorized alien’s use of false
documents on forms submitted for the purpose of securing
employment. In making this argument, respondents invoke all three
categories of preemption identified in our cases. They defend the
Kansas Supreme Court’s holding that provisions of IRCA expressly
bar their prosecutions. And they also argue that the decision below
is supported by “field” or “conflict” preemption or some
combination of the two. We consider these arguments in turn.
III
We begin with the argument that the state
criminal statutes under which respondents were convicted are
expressly preempted.
As noted, IRCA contains a provision that
expressly preempts state law, but it is plainly inapplicable here.
That provision applies only to the imposition of criminal or civil
liability on
employers and those who receive a fee for
recruiting or referring prospective employees. 8 U. S. C.
§1324a(h)(2). It does not mention state or local laws that impose
criminal or civil sanctions on employees or applicants for
employment.
The Kansas Supreme Court did not base its
holding on this provision but instead turned to §1324a(b)(5), which
is far more than a preemption provision. This provision broadly
restricts
any use of an I–9, information contained in an
I–9, and any documents appended to an I–9. Thus, unlike a typical
preemption provision, it applies not just to the States but also to
the Federal Government and all private actors.
The Kansas Supreme Court thought that the
prosecutions in these cases ran afoul of this provision because the
charges were based on respondents’ use in their W–4’s and K–4’s of
the same false Social Security numbers that they also inserted on
their I–9’s. Taken at face value, this theory would mean that no
information placed on an I–9— including an employee’s name,
residence address, date of birth, telephone number, and e-mail
address—could ever be used by any entity or person for any
reason.
This interpretation is flatly contrary to
standard English usage. A tangible object can be “contained in”
only one place at any point in time, but an item of information is
different. It may be “contained in” many different places, and it
is not customary to say that a person uses information that is
contained in a particular source unless the person makes use of
that source.
Consider a person’s e-mail address, one of the
bits of information that is called for on an I–9. A person’s e-mail
address may be “contained in” a great many places. Individuals
often provide their e-mail addresses to a wide circle of friends,
acquaintances, online vendors, work-related contacts, and others.
In addition, the records of every recipient of an e-mail from a
particular person will contain that address.[
2] In ordinary speech, no one would say that a
person who uses an e-mail address has used information that is
contained in all these places.
Suppose that John used his e-mail address five
years ago to purchase a pair of shoes and that the vendor has that
address in its files. Suppose that John now sends an e-mail to Mary
and that Mary sends an e-mail reply. No one would say that Mary has
used information contained in the files of the shoe vendor.
Or consider this bit of information: that the
first man set foot on the moon on July 20, 1969.[
3] That fact was reported in newspapers
around the world, from Neil Armstrong’s hometown newspaper, the
Wapakoneta (Ohio) Daily News[
4]
to the Soviet newspaper Izvestia
.[
5] Suppose that an elementary school student writes a
report in which she states that the first man walked on the moon in
1969. No one would say that the student used information contained
in the Wapakoneta Daily News or Izvestia if she never saw those
publications
. But it would be natural to say that the
student used information contained in a book in the school library
if that is where she got the information for her report.
Accordingly, the mere fact that an I–9 contains
an item of information, such as a name or address, does not mean
that information “contained in” the I–9 is used whenever that name
or address is later employed.
If this were not so, strange consequences would
ensue. Recall that 8 U. S. C. §1324a(b)(5) applies to the
Federal
Government. Under 26 U. S. C. §7205,
it is a crime to willfully supply false information on a W–4, and
this provision is not among those listed in 8 U. S. C.
§1324a(b)(5). Thus, if an individual provided the same false
information on an I–9 and a W–4, the Federal Government could not
prosecute this individual under 26 U. S. C. §7205 even if
the Government made no use whatsoever of the I–9. And that is just
the beginning.
Suppose that an employee truthfully states on
his I–9 that his name is Jim Smith. Under the interpretation of 8
U. S. C. §1324a(b)(5) that the Kansas Supreme Court
seemingly adopted, no one could use Jim’s name for any purpose. If
he robbed a bank, prosecutors could not use his name in an
indictment. His employer could not cut a paycheck using that name.
His sister could not use his name to mail him a birthday card.
The Kansas Supreme Court tried to fend off these
consequences by suggesting that its interpretation applied only to
the prosecution of aliens for using a false identity to establish
“employment eligibility.” 306 Kan., at 1126, 401 P. 3d, at
596. But there is no trace of these limitations in the text of
§1324a(b)(5). The point need not be belabored any further: The
argument that §1324a(b)(5) expressly bars respondents’ prosecutions
cannot be defended.
Apparently recognizing this, respondents turn to
§1324a(d)(2)(F), which prohibits use of the federal employment
verification system[
6] “for law
enforcement purposes other than” enforcement of IRCA and the same
handful of federal statutes mentioned in §1324a(b)(5): 18
U. S. C. §1001 (false statements), §1028 (identity
theft), §1546 (immigration-document fraud), and §1621
(perjury).
This argument fails because it rests on a
misunderstanding of the meaning of the federal “employment
verification system.” The sole function of that system is to
establish that an employee is not barred from working in this
country due to alienage. As described in §1324a(b), the system
includes the steps that an employee must take to establish that he
or she is not prohibited from working, the steps that an employer
must take to verify the employee’s status, and certain related
matters—such as the preservation and copy- ing of records that are
used to show authorization to work.
The federal employment verification system does
not include things that an employee must or may do to satisfy
requirements unrelated to work authorization. And completing
tax-withholding documents plays no part in the process of
determining whether a person is authorized to work.[
7] Instead, those documents are part of the
apparatus used to enforce federal and state income tax
laws.[
8]
For all these reasons, there is no express
preemption in these cases.
IV
We therefore proceed to consider respondents’
alternative argument that the Kansas laws, as applied, are
preempted by implication. This argument, like all preemption
arguments, must be grounded “in the text and structure of the
statute at issue.”
CSX Transp., Inc. v.
Easterwood,
507 U.S.
658, 664 (1993).
A
Respondents contend, first, that the Kansas
statutes, as applied, fall into a field that is implicitly reserved
exclusively for federal regulation. In rare cases, the Court has
found that Congress “legislated so comprehensively” in a particular
field that it “left no room for supplementary state legislation,”
R. J. Reynolds Tobacco Co. v.
Durham County,
479 U.S.
130, 140 (1986), but that is certainly not the situation
here.
In order to determine whether Congress has
implicitly ousted the States from regulating in a particular field,
we must first identify the field in which this is said to have
occurred. In their merits brief in this Court, respondents’ primary
submission is that IRCA preempts “the field of fraud on the federal
employment verification system,” Brief for Respondents 41
(quotation altered), but this argument fails because, as already
explained, the submission of tax- withholding forms is not part of
that system.
At some points in their brief, respondents
define the supposedly preempted field more broadly as the “field
relating to the federal employment verification system,”
id., at 42 (emphasis added); see also
id., at 40, but
this formulation does not rescue the argument. The submission of
tax- withholding forms is
fundamentally unrelated to the
federal employment verification system because, as explained, those
forms serve entirely different functions. The employment
verification system is designed to prevent the employment of
unauthorized aliens, whereas tax-withholding forms help to enforce
income tax laws. And using another person’s Social Security number
on tax forms threatens harm that has no connection with immigration
law.
For instance, using another person’s Social
Security number on tax-withholding forms affects the wages reported
to federal and state tax authorities. In addition, many
benefits—such as those for disability, unemployment, and
retirement—are tied to an individual’s work status and income.
Inaccurate data also affect the accuracy of a State’s tax
information.[
9]
It is true that employees generally complete
their W–4’s and K–4’s at roughly the same time as their I–9’s, but
IRCA plainly does not foreclose all state regulation of information
that must be supplied as a precondition of employment. New
employees may be required by law to provide all sorts of
information that has nothing to do with authorization to work in
the United States, such as information about age (for jobs with a
minimum age requirement), educational degrees, licensing, criminal
records, drug use, and personal information needed for a background
check. IRCA surely does not preclude States from requiring and
regulating the submission of all such information.
Respondents suggest that federal law precludes
their prosecutions because both the Kansas identity-theft statute
and the Kansas false-information statute require proof that the
accused engaged in the prohibited conduct for the purpose of
getting a “benefit.” Their argument is as follows. Since the
benefit alleged by the prosecution in these cases was getting a
job, and since the employment verification system concerns
authorization to work, the theory of respondents’ prosecutions is
related to that system.
This argument conflates the benefit that results
from complying with the federal employment verification system
(verifying authorization to work in the United States) with the
benefit of actually getting a job. Submitting W–4’s and K–4’s
helped respondents get jobs, but this did not in any way assist
them in showing that they were authorized to work in this country.
Thus, respondents’ “relating to” argument must be rejected, as must
the even broader definitions of the putatively preempted field
advanced by respondents at earlier points in this litigation.
Contrary to respondents’ suggestion, IRCA
certainly does not bar all state regulation regarding the “use of
false documents . . . when an unauthorized alien seeks
employment.” Brief in Opposition 21. Nor does IRCA exclude a State
from the entire “field of employment verification.”
Id., at
22. For example, IRCA certainly does not prohibit a public school
system from requiring applicants for teaching positions to furnish
legitimate teaching certificates. And it does not prevent a police
department from verifying that a prospective officer does not have
a record of abusive behavior.
Respondents argue that field preemption in these
cases “follows directly” from our decision in
Arizona,
567 U.S.
387, Brief for Respondents 45–46, but that is not so. In
Arizona, relying on our prior decision in
Hines v.
Davidowitz,
312 U.S.
52 (1941), we held that federal immigration law occupied the
field of alien registration. 567 U. S., at 400–402. “Federal
law,” we observed, “makes a single sovereign responsible for
maintaining a comprehensive and unified system to keep track of
aliens within the Nation’s borders.”
Id., at 401–402. But
federal law does not create a comprehensive and unified system
regarding the information that a State may require employees to
provide.
In sum, there is no basis for finding field
preemption in these cases.
B
We likewise see no ground for holding that the
Kansas statutes at issue conflict with federal law. It is certainly
possible to comply with both IRCA and the Kansas statutes, and
respondents do not suggest otherwise. They instead maintain that
the Kansas statutes, as applied in their prosecutions, stand as “an
obstacle to the accomplishment and execution of the full purposes”
of IRCA—one of which is purportedly that the initiation of any
legal action against an unauthorized alien for using a false
identity in applying for employment should rest exclusively within
the prosecutorial discretion of federal authorities. Brief for
Respondents 49–55. Allowing Kansas to bring prosecutions like
these, according to respondents, would risk upsetting federal
enforcement priorities and frustrating federal objectives, such as
obtaining the cooperation of unauthorized aliens in making bigger
cases.

Respondents analogize these cases to our holding
in
Arizona, 567 U. S., at 404–407—that a state law
making it a crime for an unauthorized alien to obtain employment
conflicted with IRCA, which does not criminalize that conduct—but
respondents’ analogy is unsound. In
Arizona, the Court
inferred that Congress had made a considered decision that it was
inadvisable to criminalize the conduct in question. In effect, the
Court concluded that IRCA implicitly conferred a right to be free
of criminal (as opposed to civil) penalties for working illegally,
and thus a state law making it a crime to engage in that conduct
conflicted with this federal right.
Nothing similar is involved here. In enacting
IRCA, Congress did not decide that an unauthorized alien who uses a
false identity on tax-withholding forms should not face criminal
prosecution. On the contrary, federal law makes it a crime to use
fraudulent information on a W–4. 26 U. S. C. §7205.
The mere fact that state laws like the Kansas
provisions at issue overlap to some degree with federal criminal
provisions does not even begin to make a case for conflict
preemption. From the beginning of our country, criminal law
enforcement has been primarily a responsibility of the States, and
that remains true today. In recent times, the reach of federal
criminal law has expanded, and there are now many instances in
which a prosecution for a particular course of conduct could be
brought by either federal or state prosecutors. Our federal system
would be turned upside down if we were to hold that federal
criminal law preempts state law whenever they overlap, and there is
no basis for inferring that federal criminal statutes preempt state
laws whenever they overlap. Indeed, in the vast majority of cases
where federal and state laws overlap, allowing the States to
prosecute is entirely consistent with federal interests.
In the present cases, there is certainly no
suggestion that the Kansas prosecutions frustrated any federal
interests. Federal authorities played a role in all three cases,
and the Federal Government fully supports Kansas’s position in this
Court. In the end, however, the possibility that federal
enforcement priorities might be upset is not enough to provide a
basis for preemption. The Supremacy Clause gives priority to “the
Laws of the United States,” not the criminal law enforcement
priorities or preferences of federal officers. Art. VI, cl. 2.
Finally, contrary to respondents’ suggestion,
these cases are very different from
Buckman Co. v.
Plaintiffs’ Legal Comm.,
531 U.S.
341 (2001), and
Wisconsin Dept. of Industry v.
Gould
Inc.,
475 U.S.
282 (1986). In
Buckman Co., the preempted state tort
claim for fraud on the Food and Drug Administration threatened
serious disruption of the sensitive and highly technical process of
approving medical devices. 531 U. S., at 347–353. In these
cases, the state prosecutions posed no comparable risk.
In
Gould, the decision rested on a
special preemption rule governing state laws regulating matters
that the National Labor Relations Act “protects, prohibits, or
arguably protects.” 475 U. S., at 286–289;
San Diego
Building Trades Council v.
Garmon,
359 U.S.
236, 246 (1959). No similar rule is operative or appropriate
here.

For these reasons, the judgments of the
Supreme Court of Kansas are reversed, and these cases are remanded
for further proceedings not inconsistent with this opinion.
It is so ordered.
