CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE FIFTH CIRCUIT
No. 24–813. Argued January 12, 2026—Decided April 17, 2026
The federal officer removal statute, 28 U. S. C. §1442(a)(1), authorizes
removal of state-court suits against federal officers or persons “acting
under” them “for or relating to any act under color of such office.” This
case concerns whether, for purposes of the statute, a state-court envi-
ronmental suit challenging Chevron’s crude-oil production during the
Second World War is “for or relating to” Chevron’s wartime refining of
crude oil into aviation gasoline for the U. S. military.
In 1978, Louisiana enacted the State and Local Coastal Resources
Management Act, which prohibited certain uses of Louisiana’s coastal
zone, including oil production, without a permit. The Act exempted
uses legally commenced before 1980. In 2013, Plaquemines Parish and
other parishes filed 42 state-court suits against oil and gas companies
under the Act. They alleged that the companies lacked permits and
that some uses, although initiated before 1980, were illegally com-
menced and therefore not covered by the exemption. An expert report
filed by the parish made clear that it intended to challenge certain de-
fendants’ crude-oil production during the Second World War. The re-
port alleged that Chevron failed to use steel tanks instead of earthen
pits, should not have used vertical-drilling methods, and failed to equip
fields with sufficient roads, using canals instead.
Chevron removed the suit to federal court under the federal officer
removal statute, arguing that the suit “relat[ed] to” its contractual du-
ties to refine crude oil into avgas for the military during the war. The
District Court rejected this argument and granted the parish’s motion
to remand to state court. The Fifth Circuit affirmed, agreeing that
Chevron had “acted under” a federal officer as a military contractor

Syllabus
but concluding that the suit was not “for or relating to” those acts be-
cause Chevron’s refining contract did not specify how to acquire crude
oil. Judge Oldham dissented, reasoning that crude oil was “indispen-
sable” to avgas, such that its production necessarily related to Chev-
ron’s performance of its federal avgas refining duties.
Held: Chevron has plausibly alleged a close relationship between its
challenged crude-oil production and the performance of its federal
avgas refining duties—not a tenuous, remote, or peripheral one—and
has therefore satisfied the “relating to” requirement of the federal of-
ficer removal statute. Pp. 7–12.
(a) The phrase “relating to” sweeps broadly, meaning “ ‘to stand in
some relation; to have bearing or concern; to pertain; refer; to bring
into association with or connection with.’ ” Morales v. Trans World
Airlines, Inc., 504 U. S. 374, 383. One thing can relate to another even
if the connection is “indirect,” Ingersoll-Rand Co. v. McClendon, 498
U. S. 133, 139; even if it was “not specifically designed to affect” it,
ibid.; and even without a “strict causal relationship,” Ford Motor Co.
v. Montana Eighth Judicial Dist. Court, 592 U. S. 351, 362. Accord-
ingly, a removing defendant need not show that his federal duties spe-
cifically required or strictly caused the challenged conduct.
The ordinary meaning of “relating to,” however, is not “so broad that
it is meaningless.” Rutledge v. Pharmaceutical Care Management
Assn., 592 U. S. 80, 93 (THOMAS , J., concurring). The ordinary mean-
ing requires a connection that is not “ ‘tenuous, remote, or peripheral.’ ”
Id., at 94. Ordinary readers would not understand the federal officer
removal statute to reach all suits with any attenuated connection to
federal duties. Pp. 7–9.
(b) Chevron’s suit “relat[es] to” the performance of federal duties be-
cause Chevron has plausibly alleged a close relationship between its
challenged conduct and the performance of its federal duties. This suit
implicates Chevron’s wartime efforts to produce and supply avgas’ es-
sential feedstock, so it is closely connected to Chevron’s wartime avgas
refining for the military. Much of the crude oil that Chevron produced
in Plaquemines Parish was ultimately used for its own avgas refining,
and the suit challenges Chevron’s actions that allowed it to increase
its production of crude oil during wartime. The parish’s report alleged
that Chevron’s use of the coastal zone had been illegally commenced
because of its reliance on vertical-drilling methods, canals, and
earthen pits—but using vertical-drilling methods maximized crude-oil
production; using canals saved time and materials resulting in more
timely oil production; and using earthen pits complied with the Gov-
ernment’s directive to preserve steel. The Government emphasized
the importance of increasing Chevron’s crude-oil production to support
avgas refining as part of the war effort, and it identified the oil field at

-- 2 of 22 --

Syllabus
issue as critical to the war program because it produced a preferential
kind of crude oil for refining avgas. In this all-hands-on-deck, wartime
context, Chevron needed to produce more crude oil as quickly as possi-
ble to facilitate more avgas refining, including its own. Pp. 9–10.
(c) The Court disagrees with the Fifth Circuit’s two main reasons for
ruling to the contrary. First, the Fifth Circuit reasoned that Chevron’s
refining contract did not specify how to obtain or produce crude oil, so
Chevron’s crude-oil production was unrelated to the performance of its
federal refining duties. But the ordinary meaning of “relating to” does
not require the defendant to show that his federal duties specifically
invited his challenged conduct; Chevron’s contract did not have to ex-
pressly direct or invite Chevron’s crude-oil production for that conduct
to “relate to” its avgas refining. Second, the Fifth Circuit reasoned that
the Government’s allocation of crude oil to refineries severed any rela-
tion between producing and refining. But an act can relate to its con-
sequences even when the causal chain includes actions by intermedi-
aries, see Morales, 504 U. S. 374; producing crude oil relates to refining
it into avgas, even if the Government acted as an intermediary allocat-
ing the crude oil to refineries. Pp. 10–11.
(d) The Court also disagrees with Louisiana’s argument that the re-
moval statute requires that the defendant was “acting under” a federal
officer in taking the specific actions challenged in the suit. This theory
is not consistent with the statutory text, which permits removal of
suits against officers or their agents for acts that were not done under
color of their offices, so long as the suits “relat[e] to” such acts. Louisi-
ana’s interpretation would leave the “relating to” requirement with lit-
tle, if any, independent function, impermissibly conflating the “acting
under” and “for or relating to” elements of the federal officer removal
test. Pp. 11–12.

CHEVRON USA INCORPORATED, ET AL.,
PETITIONERS v. PLAQUEMINES
PARISH, LOUISIANA, ET AL.
ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE FIFTH CIRCUIT
[April 17, 2026]
J USTICE THOMAS delivered the opinion of the Court.
Congress has long authorized federal officers and their
agents to remove suits brought against them in state court
to federal court. The federal officer removal statute author-
izes an officer or “person acting under that officer” to re-
move state suits “for or relating to any act under color of
such office.” 28 U. S. C. §1442(a)(1). In this case, Chevron
USA Inc. invoked the statute to remove to federal court an
environmental suit brought against it in Louisiana state
court. Chevron argued that the suit was removable because
it implicates Chevron’s crude-oil production during the Sec-
ond World War, when Chevron also refined crude oil into
aviation gasoline for the U. S. military. No party disputes
that Chevron “act[ed] under” federal officers when it per-
formed its refining duties. We thus decide only whether
this suit, which implicates Chevron’s wartime production of
crude oil, “relat[es] to” Chevron’s wartime aviation-gasoline
refining for the military. We hold that it does.

2 CHEVRON USA INC. v. PLAQUEMINES PARISH
Opinion of the Court
I
A
To protect the Federal Government from state-court “in-
terference with its operations,” Congress has given federal
courts jurisdiction over some suits against federal officers
or those acting under them. Watson v. Philip Morris Cos.,
551 U. S. 142, 150 (2007) (internal quotation marks omit-
ted). The current federal officer removal statute traces its
lineage to the Force Bill of 1833, which Congress passed to
enable federal customs officials to remove suits to federal
court after South Carolina began prosecuting them for en-
forcing federal law. See Tennessee v. Davis, 100 U. S. 257,
268–269 (1880); Brief for U. S. Sen. Mike Lee et al. as Amici
Curiae 4. Over the next 200 years, Congress expanded the
scope of federal officer removal beyond suits against cus-
toms officials. Id., at 4–6. Today, defendants may remove
to federal court any
“civil action or criminal prosecution that is commenced
in a State court and that is against or directed to . . .
[t]he United States or any agency thereof or any officer
(or any person acting under that officer) of the United
States or of any agency thereof . . . for or relating to any
act under color of such office.” 28 U. S. C. §1442(a)(1).
Under the federal officer removal statute, a removing de-
fendant must satisfy three requirements. First, the remov-
ing defendant must be the United States, a federal agency,
a federal officer, or a person “acting under” a federal officer,
such as certain private parties hired to assist federal offic-
ers. See Watson, 551 U. S., at 148–153. Second, the suit
must be “for or relating to any act under color of such office.”
§1442(a)(1). Third, the removing defendant must assert “a
colorable federal defense.” Mesa v. California, 489 U. S.
121, 129 (1989); see id., at 136–137 (grounding this require-
ment in Article III of the Constitution). This case concerns
the second requirement.

When the United States entered the Second World War,
aviation gasoline—or “avgas”—became critical for the mili-
tary. The war spurred “a race to gain mastery of the skies.”
A. Baime, The Arsenal of Democracy 133 (2014). Success
in the air required high-octane avgas, a “superfuel” for com-
bat aircraft that helped to produce “more speed, more
power, [and] quicker take-off.” J. Frey & H. Ide, A History
of the Petroleum Administration for War, 1941–1945,
p. 193 (1946) (P. A. W. History). Avgas refining therefore
had to keep pace with the “astonishing expansion of aerial
activity” during the war. Ibid. In June 1940, the U. S. mil-
itary used about 4,000 barrels of avgas per day, while Amer-
ican industry could refine 30,000 to 40,000 barrels per day.
Id., at 194. By 1944, at the height of U. S. involvement in
the war, the U. S. military needed 636,000 barrels per day.
Ibid.
President Franklin D. Roosevelt created the Petroleum
Administration for War (P. A. W.) to ensure that the United
States would have enough fuel to win the war. See id., at
14–15, 44–45. The P. A. W. oversaw the entire oil industry,
from production to transportation to refinement. Within
two weeks after the attack on Pearl Harbor, the P.A.W. is-
sued a directive for “the production of 100 octane aviation
gasoline [to] be greatly increased.” 7 Fed. Reg. 41 (1942).
The message was clear: “ ‘[F]orget economic considera-
tions—forget everything except getting out more and more
100-octane [avgas] as quickly as you can.’ ” P. A. W. History
199. With the P. A. W.’s assistance, the Federal Govern-
ment, through the Defense Supplies Corporation, con-
tracted with dozens of avgas refineries to secure avgas for
the military.

4 CHEVRON USA INC. v. PLAQUEMINES PARISH
Opinion of the Court
The Government entered an avgas refining contract with
a predecessor of Chevron, the Texas Company.1 In its con-
tract with the Government, Chevron agreed to work “day
and night” to quadruple its avgas refining capacity at its
Texas refinery. App. to Pet. for Cert. 150–151. It agreed
that the Government could request that it buy avgas com-
ponents, including crude oil, from other firms. And, it
agreed that the Government could “at any time” purchase
all of Chevron’s excess avgas. Id., at 156.
The Government knew that to refine crude oil into avgas,
Chevron needed crude oil. The Government’s contract with
Chevron adjusted the price of avgas based on the cost of ob-
taining crude oil. The P. A. W. allocated crude oil to specific
refiners to maximize output. And, the P. A. W. required
production methods that increased crude-oil production,
such as vertical drilling. 8 Fed. Reg. 3955, 3957 (1943).
At the same time, Chevron produced crude oil in
Plaquemines Parish, Louisiana, including in two fields rel-
evant to this case—the Delacroix Island and Delta Duck
Club fields. Some of the crude oil produced in both fields
went to the Texas refinery at which Chevron refined crude
oil into avgas for the military during the war. In 1942,
Chevron was refining 4,000 barrels of crude oil per day from
fields in Plaquemines Parish.

In 1978, Louisiana enacted the State and Local Coastal
Resources Management Act. La. Rev. Stat. Ann. §49:214.21
et seq. (West 2023). The Act established a new permitting
program that took effect in 1980. It prohibits any “[u]ses of
state concern” of Louisiana’s coastal zone, including oil pro-
duction, unless the user first obtains a permit.
§§49:214.25(A)(1)(f ), 49:214.30(A)(1). But, it exempts from

pany’s acts were Chevron’s acts for the purposes of this case. We thus

Opinion of the Court
its permitting requirement “[i]ndividual specific uses le-
gally commenced or established prior to the effective date
of the coastal use permit program.” §49:214.34(C)(2).
In 2013, Plaquemines Parish, along with other parishes,
filed 42 state-court suits against oil and gas companies un-
der the Act. The parishes alleged that the companies lacked
permits for their uses of the coastal zone, and that some of
these uses, although initiated before 1980, were illegally
commenced and not covered by the Act’s exemption for uses
that commenced before 1980. The State of Louisiana and
its Department of Energy and Natural Resources inter-
vened in support of the parishes.
Plaquemines Parish filed an expert report in one of these
suits that made clear that it intended to challenge certain
defendants’ crude-oil production during the Second World
War. The report alleged that several uses had been illegally
commenced during the war, making them “violations which
provide the basis for defendant liability.” Preliminary Ex-
pert Report on Violations, No. 2:18–cv–5256 (ED La.), ECF
Doc. 1–3, p. 4. As to Chevron, the report identified produc-
tion activities in the Delacroix Island field, where Chevron
began drilling in 1941. Specifically, the report alleged that
Chevron failed to use steel tanks instead of earthen pits. It
alleged that Chevron should not have used vertical-drilling
methods, which allegedly harmed the environment more
than alternative methods. And, it alleged that Chevron
failed to equip Delacroix Island with sufficient roads for
transportation and instead primarily used canals. The re-
port alleged that these production activities showed “bad
faith” and failed to protect the “marshland from contamina-
tion and excessive land losses,” making Chevron subject to
liability under the Act. ECF Doc. 1–5, p. 35. All agree at
this stage that this report reflects the parishes’ general the-
ories of liability across the 42 suits.
Several defendants removed the suits against them un-
der the federal officer removal statute. 28 U. S. C.

6 CHEVRON USA INC. v. PLAQUEMINES PARISH
Opinion of the Court
§1442(a)(1). The removal effort focused on the connection
between these 1940s allegations and the defendants’ 1940s
federal contracts. Because the allegations concerned their
1940s crude-oil production, the defendants argued that the
suits “relat[ed] to” their contractual duties to refine crude
oil into avgas for the military at the same time.
In this case, the parish’s suit challenged Chevron’s con-
duct at the Delta Duck Club field, where Chevron drilled
during the war. Chevron removed on the theory that the
suit alleged that Chevron illegally produced crude oil in the
Delta Duck Club field, while it simultaneously served as an
avgas refiner for the military. The parish’s state-court com-
plaint, like its expert report in the parallel case, alleged
that Chevron’s use of the coastal zone had been illegally
commenced prior to the effective date of the Act, citing its
crude-oil production processes, use of earthen pits, and
dredging of canals. Chevron’s notice of removal thus ar-
gued that the complaint, alongside the parishes’ report,
showed that the parish would target acts related to its per-
formance of federal duties during the war. The District
Court rejected this argument and granted the parish’s mo-
tion to remand to state court.
The Fifth Circuit affirmed. The court agreed with Chev-
ron that it had “acted under” a federal officer because it re-
fined crude oil into avgas as a military contractor.
Plaquemines Parish v. BP America Production Co., 103
F. 4th 324, 334–335 (2024). But, the Fifth Circuit con-
cluded that the suit was not “for or relating to” those acts.
It agreed that the complaint, when “read in conjunction
with the [expert] report,” targeted crude-oil production ac-
tivities during the war. Id., at 337. Nonetheless, it con-
cluded that this suit, despite challenging Chevron’s crude-
oil production, did not relate to the performance of Chev-
ron’s avgas refining contract because the contract did not
specify how to acquire crude oil. Id., at 340–341.

Opinion of the Court
Judge Oldham dissented. He reasoned that crude oil was
“indispensable” to avgas, such that its production neces-
sarily related to Chevron’s performance of its federal avgas
refining duties. Id., at 348.
We granted Chevron’s petition for a writ of certiorari.
605 U. S. 1009 (2025).
II
We address whether this suit, which implicates Chev-
ron’s wartime production of crude oil, is “for or relating to”
Chevron’s wartime refining of crude oil into avgas for the
military.2 28 U. S. C. §1442(a)(1). Chevron’s wartime
crude-oil production was closely connected to its wartime
avgas refining, so the parish’s suit challenging that crude-
oil production relates to that refining.
A
The phrase “relating to” sweeps broadly. It means “ ‘to
stand in some relation; to have bearing or concern; to per-
tain; refer; to bring into association with or connection
with.’ ” Morales v. Trans World Airlines, Inc., 504 U. S. 374,
383 (1992) (quoting Black’s Law Dictionary 1158 (5th ed.
1979)). One thing can relate to another even if the connec-
tion is “indirect.” Ingersoll-Rand Co. v. McClendon, 498
U. S. 133, 139 (1990). One thing can relate to another even
if it was “not specifically designed to affect” it. Ibid. And,
one thing can relate to another even without a “strict causal
relationship.” Ford Motor Co. v. Montana Eighth Judicial
Dist. Court, 592 U. S. 351, 362 (2021); see also Altria Group,
Inc. v. Good, 555 U. S. 70, 85–86 (2008). Accordingly, a re-
moving defendant need not show that his federal duties

2 The Fifth Circuit held that Chevron satisfied the first requirement of
the removal statute because it “act[ed] under” a federal officer when it
refined crude oil into avgas for the military pursuant to a federal con-
tract. No party disputes that Chevron acted under a federal officer in
that capacity. We assume, without deciding, that it did.

specifically required or strictly caused the challenged con-
duct.3 See District of Columbia v. Exxon Mobil Corp., 89
F. 4th 144, 155 (CADC 2023) (collecting cases).
The ordinary meaning of “relating to,” however, is not “so
broad that it is meaningless.” Rutledge v. Pharmaceutical
Care Management Assn., 592 U. S. 80, 93 (2020) (T HOMAS ,
J., concurring). To be sure, in a literalist sense, “everything
is related to everything else.” California Div. of Labor
Standards Enforcement v. Dillingham Constr., N. A., Inc.,
519 U. S. 316, 335 (1997) (Scalia, J., concurring). But, gen-
erally in statutory interpretation, “it is the ordinary, not lit-
eralist, meaning that is the better one.” Rutledge, 592 U. S.,
at 93 (THOMAS , J., concurring); see A. Scalia, A Matter of
Interpretation 24 (1997) (“the good textualist is not a liter-
alist”).
The ordinary understanding of “relating to” requires a
connection that is not “tenuous, remote, or peripheral.”
Rutledge, 592 U. S., at 94 (THOMAS , J., concurring) (internal
quotation marks omitted). Ordinary readers would not un-
derstand the statement that someone is “ ‘related to Joe’ ” to
refer to “a mutual tie to Adam and Eve.” Ibid. Nor would

3 Congress only recently adopted the “relating to” statutory language.
Before 2011, the statute required that the suit be “for” an act under color
of office. 28 U. S. C. §1442(a)(1) (2006 ed.). This Court had interpreted
that language to require the removing defendant to “show a nexus, a
‘ “causal connection” between the charged conduct and asserted official
authority.’ ” Jefferson County v. Acker, 527 U. S. 423, 431 (1999). In
2011, Congress broadened the statute by authorizing removal of suits
“for or relating to” an act under color of office. §2(b), 125 Stat. 545.

Brazil Set Off a Tornado in Texas?, at the American Association for the

duties. For instance, the D. C. Circuit has held that a false-
advertising suit targeting an oil company’s statements to
consumers about the future effects of fossil fuels on climate
change did not relate to its decades-earlier production for
the Government. See Exxon Mobil Corp., 89 F. 4th, at 156;
see also Minnesota v. American Petroleum Inst., 63 F. 4th
703, 715 (CA8 2023).
B
Chevron’s case fits comfortably within the ordinary
meaning of a suit “relating to” the performance of federal
duties. Chevron has plausibly alleged a close relationship
between its challenged conduct and the performance of its
federal duties—not a tenuous, remote, or peripheral one.
Cf. Dart Cherokee Basin Operating Co. v. Owens, 574 U. S.
81, 89 (2014) (explaining that, when reviewing a remand to
state court, we credit plausible factual allegations by the
removing party).
This suit implicates Chevron’s wartime efforts to produce
and supply avgas’ essential feedstock, so it is closely con-
nected to Chevron’s wartime avgas refining for the military.
Much of the crude oil that Chevron produced in the Delta
Duck Club field was ultimately used for its own avgas re-
fining. And, as the Fifth Circuit assumed and no party dis-
putes, this suit will challenge Chevron’s actions that al-
lowed it to increase its production of crude oil in the Delta
Duck Club field during wartime. See 103 F. 4th, at 337.
The parish’s report alleged that Chevron’s use of the coastal
zone had been illegally commenced because of its reliance
on vertical-drilling methods, canals, and earthen pits. See
ibid. But, using vertical-drilling methods “maximize[d]
production” of crude oil. App. 19. Using canals instead of
building roads saved “time, materials, and manpower,” re-
sulting in more “timely oil production.” Id., at 18. And,
using earthen pits complied with the P. A. W.’s directive to
preserve steel. See id., at 22; 6 Fed. Reg. 5880 (1941). If

-- 12 of 22 --

10 CHEVRON USA INC. v. PLAQUEMINES PARISH
Opinion of the Court
Chevron had refrained from these actions and produced less
crude oil as a result, its avgas refining for the military may
have suffered.
Moreover, the Government emphasized the importance of
increasing Chevron’s crude-oil production to support avgas
refining as part of the war effort. The P. A. W. identified
Delta Duck Club as a “ ‘Critical Fiel[d ] Essential to the War
Program’ ” because it produced a “ ‘preferential’ ” kind of
crude oil for refining avgas. App. 112–113. Under Chev-
ron’s refining contract, the Government paid more for avgas
when the price of obtaining crude oil increased. Meanwhile,
the P. A. W. required the development of plans “to increase
to a maximum the production of all grades of aviation gas-
oline . . . in the shortest possible time,” including by ad-
dressing the need for components such as crude oil. 6 Fed.
Reg. 6433–6434. And, the P. A. W.’s regulations required
the vertical-drilling methods challenged by the parish as
part of its effort to “provide adequate supplies of petroleum
for military and other essential purposes.” 8 Fed. Reg.
3955; see id., at 3957. In this all-hands-on-deck, wartime
context, Chevron needed to produce more crude oil as
quickly as possible to facilitate more avgas refining, includ-
ing its own.
Chevron has therefore satisfied the “relating to” require-
ment. This suit implicates acts by Chevron that are closely
connected to the performance of its federal duties.5
C
We disagree with the Fifth Circuit’s two main reasons for
ruling to the contrary.
First, the Fifth Circuit reasoned that Chevron’s refining
contract did not specify how to obtain or produce crude oil,
so Chevron’s crude-oil production was unrelated to the

cifically invited his challenged conduct. See, supra, at 7–8.
For example, we have held in the preemption context that
a state law can “relate to” benefit plans even when the
law was “not specifically designed to affect such plans.”
Ingersoll-Rand, 498 U. S., at 139. Likewise, Chevron’s con-
tract did not have to expressly direct or invite Chevron’s
crude-oil production for that conduct to “relate to” its avgas
refining.
Second, the Fifth Circuit reasoned that the P. A. W.’s al-
location of crude oil to refineries severed any relation be-
tween producing and refining. 103 F. 4th, at 344. But, as
this Court’s decision in Morales illustrates, an act can re-
late to its consequences even when the causal chain in-
cludes actions by intermediaries. Morales concerned
whether state rules for advertising “ ‘relat[ed]’ ” to airline
“ ‘rates’ ” and were therefore preempted by a federal statute.
504 U. S., at 378–379. This Court explained that if States
restrict advertising, the market puts less pressure on air-
lines to “price competitively.” Id., at 388 (internal quotation
marks omitted). Thus, advertising rules related to rates,
even though advertising affects rates only through the acts
of an intermediary, the consumer. Id., at 389. Likewise,
producing crude oil relates to refining it into avgas, even if
the P. A. W. acted as an intermediary allocating the crude
oil to refineries.
D
Finally, we disagree with Louisiana’s argument that it
should prevail on an alternative theory. On Louisiana’s
view, this case should not turn on the meaning of “relating
to” at all. Instead, Louisiana argues, the removal statute
requires that the defendant was “acting under” a federal of-
ficer in taking the specific actions challenged in the suit.

12 CHEVRON USA INC. v. PLAQUEMINES PARISH
Opinion of the Court
Brief for Respondent State of Louisiana et al. 18, 21. Loui-
siana does not dispute that Chevron acted under a federal
officer while engaged in avgas refining. But, because Chev-
ron did not produce crude oil pursuant to a federal contract,
Louisiana reasons that the suit is not against a defendant
“acting under” an officer.
Louisiana’s theory is not consistent with the statutory
text. The statute permits the removal of state-court suits
against “any officer (or any person acting under that of-
ficer)” that are “for or relating to any act under color of such
office.” 28 U. S. C. §1442(a)(1). It contemplates removal of
suits against officers or their agents for acts that were not
done under color of their offices, so long as the suits “relat[e]
to” such acts. Louisiana’s interpretation would leave the
“relating to” requirement with little, if any, independent
function. As the Fifth Circuit explained, Louisiana’s inter-
pretation “impermissibly conflates the ‘distinct’ ‘acting un-
der’ and ‘connected or associated with’ elements of the fed-
eral officer removal test.” 103 F. 4th, at 335. We generally
do not read a statute “in a way that makes part of it redun-
dant.” National Assn. of Home Builders v. Defenders of
Wildlife, 551 U. S. 644, 669 (2007).
III
The Fifth Circuit erred in concluding at this stage that
the suit against Chevron was not “for or relating to” its per-
formance of federal duties. Accordingly, we vacate the judg-
ment of the Fifth Circuit and remand the case for further
proceedings consistent with this opinion.
It is so ordered.
JUSTICE ALITO took no part in the decision of this case.

SUPREME COURT OF THE UNITED STATES
No. 24–813
CHEVRON USA INCORPORATED, ET AL.,
PETITIONERS v. PLAQUEMINES
PARISH, LOUISIANA, ET AL.
ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE FIFTH CIRCUIT
[April 17, 2026]
J USTICE J ACKSON, concurring in the judgment.
The Court correctly holds that the underlying lawsuit is
“for or relating to” Chevron’s acts done “under color of [fed-
eral] office.” 28 U. S. C. §1442(a)(1); see ante, at 12. But I
disagree with the majority’s conclusion that the federal
officer removal statute’s “for or relating to” language re-
quires only an indirect relationship between the conduct
targeted by the lawsuit and the asserted federal duties. See
ante, at 7–8. In my view, the statute demands more.
Understood in the context of its statutory and legislative
history, §1442(a)(1) requires a causal nexus between the
targeted conduct and the federal duties, as I explain below.
Chevron satisfies the causal-nexus requirement on the
facts presented here, so I agree that the Fifth Circuit’s rul-
ing must be vacated. I therefore respectfully concur only in
the majority’s judgment.
I
A
Since 1948, Congress has authorized federal officers, and
people acting under federal officers, to remove lawsuits
brought “for any act under color of [federal] office.” Act of
June 25, 1948, §1442(a)(1), 62 Stat. 938. We interpreted
this statutory language to require “a causal connection

JACKSON, J., concurring in judgment
between the charged conduct and asserted official author-
ity.” Willingham v. Morgan, 395 U. S. 402, 409 (1969) (in-
ternal quotation marks omitted). In other words, we held
that the federal directive giving rise to the authority to act
must be a but-for cause of the conduct challenged by the
lawsuit. See Maryland v. Soper, 270 U. S. 9, 33 (1926) (ex-
plaining that, under a similar statute, a federal official
could remove a prosecution to federal court if the case was
“based on or arises out of the acts he did under authority of
federal law in the discharge of his duty and only by reason
thereof ”); accord, Willingham, 395 U. S., at 409.
Congress amended the federal officer removal statute in
2011, adding the “or relating to” language. See Removal
Clarification Act of 2011, §2(b), 125 Stat. 545. The question
the Court answers today is what this addition means.
B
In responding to this inquiry, the majority considers in
isolation the “ordinary meaning” of the phrase “relating to.”
Ante, at 8 (internal quotation marks omitted). Based on our
case law interpreting that phrase in other contexts, the ma-
jority concludes that this language requires only an indirect
relationship between the conduct alleged in the lawsuit and
the asserted federal duties. Ante, at 7–9. Accordingly, in
the majority’s view, Congress’s addition of “or relating to”
jettisoned the causal-nexus test in favor of a looser stand-
ard. Ante, at 8, and n. 3.
I think the Court should interpret the “relating to” addi-
tion primarily by determining what Congress intended to
accomplish with this amendment. Learning Resources, Inc.
v. Trump, 607 U. S. ___, ___–___ (2026) (J ACKSON, J., con-
curring in part and concurring in judgment) (slip op., at 1–
2). Indeed, the Court’s “fundamental task” in interpreting
federal statutes is to give effect to Congress’s intent. R.
Katzmann, Judging Statutes 31 (2014) (Katzmann); see
Pennington v. Coxe, 2 Cranch 33, 59 (1804) (opinion for the

JACKSON, J., concurring in judgment
Court by Marshall, C. J.) (“It is the duty of the court to dis-
cover the intention of the legislature, and to respect that
intention”). And the Court faithfully discharges this duty
when it considers all reliable evidence of Congress’s in-
tent—including statutory and legislative history. See
United States v. Hansen, 599 U. S. 762, 775 (2023) (“Statu-
tory history is an important part of [the] context” in which
we interpret text); Katzmann 38 (“Legislative history . . .
can help [judges] understand what the law means”).
Here, the statutory and legislative history is clear: Con-
gress did not set out to change the causal-nexus require-
ment with its 2011 amendment. Rather, the “relating to”
addition was motivated by a problem entirely separate from
the causal-nexus requirement.
At the time of the amendment, 40 States had laws au-
thorizing private parties to compel document production or
depositions before they commenced a lawsuit. See Removal
Clarification Act of 2010: Hearing on H. R. 5281 before the
Subcommittee on Courts and Competition Policy of the
House Committee on the Judiciary, 111th Cong., 2d Sess.,
1 (2010) (House Hearings).* Federal officers were some-
times the target of such presuit discovery proceedings.
H. R. Rep. No. 112–17, pt. 1, pp. 3–4 (2011) (H. R. Rep.).
Courts were split, however, on whether federal officers
could remove presuit discovery proceedings to federal court
under §1442(a)(1). House Hearings, at 1–2; compare Price
v. Johnson, 600 F. 3d 460, 462 (CA5 2010) (reviewing Dis-
trict Court order determining such a proceeding was not re-
movable), with In re Subpoena In Collins, 524 F. 3d 249,
251 (CADC 2008) (determining such a proceeding was re-
movable).
——————
*The House Hearings were for a predecessor bill proposed the year be-
fore the Removal Clarification Act was passed. That predecessor bill in-
cluded the “or relating to” language that was ultimately enacted. See
H. R. 5281, 111th Cong., 2d Sess., §2(b)(2) (2010).

4 CHEVRON USA INC. v. PLAQUEMINES PARISH
JACKSON, J., concurring in judgment
Congress amended the federal officer removal statute to
clarify that presuit discovery proceedings targeting federal
officers were removable. H. R. Rep., at 4. Congress made
substantive changes to that end; for example, it specifically
stated that “any proceeding” in which “a judicial order, in-
cluding a subpoena for testimony or documents, is sought
or issued” was removable. §2(a)(1), 125 Stat. 545 (codified
at 28 U. S. C. §1442(d)(1)); see H. R. Rep., at 4.
Congress also made several “conforming amendments.”
§2(b), 125 Stat. 545. The addition of the “or relating to” lan-
guage to §1442(a)(1) was one of them. 125 Stat. 545 (refer-
ring to this change as a “conforming amendment”); accord,
House Hearings, at 44 (describing this as a “minor chang[e]
to existing §1442(a) [to] make it consistent” with the sub-
stantive changes). The addition of “or relating to” was not
a substantive change.
C
That the addition of “or relating to” was a “conforming
amendment” is meaningful. Congress rarely changes the
substance of a statute through “mere conforming amend-
ment[s].” INS v. Stevic, 467 U. S. 407, 428 (1984). Such
amendments are typically “minor tweak[s],” intended to
harmonize or clarify amended statutory provisions. Cyan,
Inc. v. Beaver County Employees Retirement Fund, 583
U. S. 416, 430 (2018); accord, Stevic, 467 U. S., at 428.
Thus, it would be passing strange to conclude that “Con-
gress made a radical—but entirely implicit—change” to the
standard for federal officer removal through a conforming
amendment. Director of Revenue of Mo. v. CoBank ACB,
531 U. S. 316, 324 (2001).
And indeed, the legislative history here confirms that
Congress did no such thing. It makes crystal clear that the
Removal Clarification Act was “not changing the underly-
ing removal law,” but was instead simply clarifying that
§1442 would apply “anytime a legal demand is made on a

JACKSON, J., concurring in judgment
Federal officer for any act done under their official capac-
ity.” House Hearings, at 2; see id., at 13 (testimony of the
House General Counsel that the bill “does not alter the
standard for general removal for Federal officer removal
under [§]1442”); id., at 17 (“[U]nder the terms of the
bill . . . , each of the currently existing requirements of the
federal officer removal statute still must be met for removal
to be permitted”); 157 Cong. Rec. 2792 (2011) (statement of
Rep. Jackson Lee that the bill “does not make any changes
to the underlying removal law”). Moreover, the history es-
tablishes that Congress knew the removal law it was
amending required a causal nexus. See H. R. Rep., at 3
(“Federal officers . . . must demonstrate a causal connection
between the charged conduct and asserted official author-
ity”). So, with full knowledge of the causal-nexus test, Con-
gress made only a “conforming” change—it did not alter the
substantive requirements for removal.
This is not to say that the “or relating to” language served
no purpose. By adding it, Congress confirmed that sub-
poena enforcement and presuit discovery proceedings “fall
within the scope of Section 1442.” House Hearings, at 20
(testimony of the House General Counsel).
The nature of presuit discovery proceedings necessitated
such confirmation. Presuit discovery proceedings seek to
get information, not to accuse the target of engaging in un-
lawful conduct. Thus, to describe a subpoena or a deposi-
tion as being “for” unlawful conduct is factually inaccurate.
If the statute permitted removal of only those proceedings
that are “for” federally directed conduct, then arguably that
statutory provision would not authorize removal of presuit
discovery proceedings. But presuit discovery proceedings
are “related to” a defendant’s federally directed conduct.
See Brief for Former Governor John Bel Edwards as Ami-
cus Curiae 12–13. So, “[b]ecause the amended §1442 would
now include proceedings that do not seek to impose civil li-
ability or a criminal penalty on the federal officer, [the

-- 20 of 22 --

statute] allows removal not only in proceedings ‘for’ acts un-
der color of the federal office but also in proceedings ‘relat-
ing to’ such acts.” House Hearings, at 68 (statement of Ar-
thur D. Hellman, University of Pittsburgh School of Law).
In short, by adding “or relating to,” Congress confirmed
that the substantive changes “broaden[ed] the universe of
acts that enable Federal officers to remove to Federal
court.” H. R. Rep., at 6. The amendment clarified that pre-
suit discovery proceedings were squarely within “the uni-
verse of acts” that a federal officer could remove. But Con-
gress did not intend to change any of the underlying
removal requirements—including the causal-nexus test.
II
Although the majority and I interpret the “for or relating
to” requirement differently, we agree that the state lawsuit
here satisfies this requirement. The lawsuit targets Chev-
ron’s crude-oil production activities. And as the majority
explains, Chevron’s predecessor contracted with the Fed-
eral Government during the Second World War to produce
aviation gasoline (“avgas”), a product refined from crude oil.
Ante, at 3–4.
Chevron used much of the crude oil it pumped from its
Louisiana oil fields to refine into avgas during the war.
This was no accident. The crude oil from Chevron’s Louisi-
ana fields was particularly well-suited for refining into
avgas, and the Federal Government pushed its refiners, in-
cluding Chevron, to produce more and more avgas. Ante, at
10. This in turn demanded an ever-increasing supply of
crude oil. Ibid. Chevron therefore produced crude oil, at
least in part, to meet the demands of its federal contracts—
satisfying the causal-nexus requirement.
The Fifth Circuit erred in concluding that the removal
statute’s “for or relating to” requirement was not met under
the circumstances presented here. It faulted Chevron for
failing to identify a specific contractual directive

JACKSON, J., concurring in judgment
“pertaining to oil production.” Plaquemines Parish v. BP
America Production Co., 103 F. 4th 324, 341 (2024). But
Chevron’s federal contracts can be a but-for cause of
the challenged crude-oil production without specifically di-
recting that production. Because the Fifth Circuit’s
contractual-directive demand goes a step further than even
the causal-nexus test, I agree with the majority that the
Fifth Circuit’s judgment must be vacated.
