APPLICATION TO VACATE STAY OF PRELIMINARY INJUNCTION

ISSUED BY THE UNITED STATES

COURT OF APPEALS FOR THE FIFTH CIRCUIT

_______________

Pursuant to Rule 23 of the Rules of this Court and the All

Writs Act, 28 U.S.C. 1651, the Solicitor General, on behalf of the

United States of America, respectfully applies for vacatur of the

stay issued on March 2, 2024, by the United States Court of Appeals

for the Fifth Circuit (App., infra, 1a-2a).

This suit was brought by the United States to enjoin the

enforcement of a new Texas law, Senate Bill 4 (SB4), that would

directly regulate the entry and removal of noncitizens. SB4, which

was to go into effect on March 5, 2024, would impose state criminal

penalties on noncitizens who unlawfully enter or reenter Texas

from Mexico and would require Texas courts to order the removal of

those noncitizens to Mexico without Mexico’s consent and without

observing the substantive or procedural requirements of federal

law governing removal.

SB4 is flatly inconsistent with this

2

Court’s decision in Arizona v. United States, 567 U.S. 387 (2012),

and more than a century of this Court’s precedents.

Those deci-

sions recognize that the authority to admit and remove noncitizens

is a core responsibility of the National Government, and that where

Congress has enacted a law addressing those issues, state law is

preempted.

The district court adhered to those principles and

granted a preliminary injunction preventing enforcement of SB4.

Respondents appealed and moved for a stay pending appeal and

an immediate administrative stay. Less than 24 hours later, before

the United States had filed a full response to the stay motion,

the court of appeals granted what it called an “administrative

stay,” stayed the effect of that stay for seven days “pending an

application to the Supreme Court of the United States,” expedited

the appeal, and deferred the motion for a stay pending appeal to

the merits panel.

App., infra, 2a.

Absent this Court’s intervention, SB4 will go into effect at

12:01 a.m. on March 10, 2024, profoundly altering the status quo

that has existed between the United States and the States in the

context of immigration for almost 150 years.

And despite the 114-

page district court opinion detailing multiple independent reasons

why the law is invalid, that disruptive change would occur without

any reasoned ruling by the court of appeals.

Instead, by purport-

ing to grant an “administrative” stay but deferring action on the

underlying stay motion indefinitely, the court effectively granted

a stay pending appeal without engaging in the necessary consider-

3

ation of likelihood of success on the merits, the balance of harms,

or the public interest.

Each of those factors makes clear that no

stay is warranted here.

On the merits, SB4 is both field and conflict preempted. This

Court has long recognized that the regulation of entry and removal

of noncitizens is inseparably intertwined with the conduct of foreign relations and thus vested “solely in the Federal Government.”

Truax v. Raich, 239 U.S. 33, 42 (1915).

In the Immigration and

Nationality Act (INA), 8 U.S.C. 1101 et seq., Congress has created

a comprehensive regime governing the admission and removal of

noncitizens. And because the federal government has fully occupied

the field of entry and removal, even “complementary state regulation” is preempted.

See Arizona, 567 U.S. at 401.

Just as Arizona

could not “add[] a state-law penalty” for failure to comply with

the INA’s registration requirements, Texas may not impose statelaw criminal penalties for violations of federal entry and reentry

provisions and may not implement state-law “decision[s] on removability.” Id. at 409. Those matters are committed to the National

Government because, inter alia, they “touch on foreign relations.”

Id. at 401, 409.

Indeed, because entry and removal are so central

to federal immigration authority, the preemptive force of federal

law is even plainer in this case than it was in Arizona.

SB4 also conflicts with federal law in multiple respects.

It

prevents the Nation from speaking “with one voice” in matters

involving foreign affairs.

Arizona, 567 U.S. at 409.

It exceeds

4

the carefully limited circumstances in which Congress has authorized state officers to perform the functions of federal immigration

officers or otherwise assist those officers in performing their

duties.

It disregards the INA’s reticulated procedures for making

removal determinations.

It provides for prosecution of nonciti-

zens for violating prohibitions on entry or reentry, thus intruding

upon federal immigration officers’ determinations regarding how to

address a particular noncitizen’s circumstances -- e.g., by immediately removing rather than prosecuting the noncitizen.

And it

requires state judges to order noncitizens removed to Mexico without Mexico’s consent and without adhering to the congressionally

mandated process for selecting the country of removal.

SB4 also violates the Foreign Commerce Clause.

Like the

Interstate Commerce Clause, that Clause encompasses regulation of

the movement of persons across territorial borders.

States v. Guest, 383 U.S. 745, 758-759 (1966).

See United

And it bars state

laws that prevent the federal government from speaking with one

voice in matters involving foreign affairs, as SB4 manifestly does.

See Japan Line Ltd. v. Los Angeles Cnty., 441 U.S. 434, 451 (1979).

In response to the obvious legal infirmities of its law, Texas

has taken the extraordinary and unprecedented position that at

least some applications of SB4 are valid under the State War Clause

of the Constitution, which generally prohibits States from “engag[ing] in War,” with a narrow exception when a State is “actually

invaded, or in such imminent Danger as will not admit of delay.”

5

U.S. Const. Art. I, § 10, Cl. 3.

here.

That Clause has no application

A surge of unauthorized immigration plainly is not an in-

vasion within the meaning of the State War Clause.

And even if it

were, the Clause does not permit States to contradict the federal

government’s considered response to any invasion that has occurred.

Here, Congress has taken that subject fully in hand by

enacting the INA, and the State War Clause does not exempt Texas

from the Supremacy Clause or the preemption principles it embodies.

The balance of harms and the public interest overwhelmingly

support vacating the court of appeals’ stay and preserving the

status quo while this litigation proceeds.

By allowing Texas to

remove noncitizens to Mexico without its consent, SB4 would have

significant and immediate adverse effects on the United States’

relationship with Mexico -- a relationship that is critical to the

federal government’s ability to effectively address immigration at

the southwest border.

SB4 would harm the federal government’s

relationship with other countries and prevent the United States

from conducting assessments under treaties concerning removal to

countries where the noncitizen may be persecuted or tortured.

And

beyond its disruptive foreign relations effects, SB4 would create

chaos in the United States’ efforts to administer federal immigration laws in Texas.

Texas faces no remotely comparable harms from the preliminary

injunction.

Vacating the stay will merely preserve the longstand-

ing status quo while the litigation proceeds, just as the relevant

6

provisions of the state law in Arizona were enjoined throughout

the litigation in that case.

See 567 U.S. at 394.

Both the law

and the equities overwhelmingly favor the same result here.

We respectfully request that this Court act on this application before the court of appeals’ stay of its own order expires

and SB4 is permitted to take effect at 12:01 a.m. on Sunday, March

10.

Alternatively, if the Court does not act by then, we respect-

fully request the Court extend the court of appeals’ seven-day

stay to preserve the status quo pending the Court’s consideration

of the application.

STATEMENT

A.

Background

1.

The INA establishes a comprehensive federal statutory

regime for the regulation of immigration.

Congress granted the

Attorney General and the Secretary of Homeland Security (Secretary) the authority to administer that regime.

and (g); 6 U.S.C. 251.

8 U.S.C. 1103(a)

As relevant here, the INA sets forth a

comprehensive framework with detailed rules governing the entry

and removal of noncitizens.1

It identifies who may and may not be

admitted to the United States, see, e.g., 8 U.S.C. 1181, 1182,

1188; prescribes how noncitizens may enter the country lawfully,

see, e.g., 8 U.S.C. 1223-1225; and imposes penalties on those who

unlawfully enter or reenter the country, see 8 U.S.C. 1325, 1326.

This application uses the term “noncitizen” as equivalent to the statutory term “alien.” See Barton v. Barr, 140 S.

Ct. 1442, 1446 n.2 (2020) (quoting 8 U.S.C. 1103(a)(3)).

1

7

The INA also comprehensively governs the removal of noncitizens.

Congress provided for formal removal proceedings to be

conducted before the Immigration Court, a specialized tribunal in

the Department of Justice.

With limited exceptions for other

federally initiated procedures, the formal removal proceedings are

the “sole and exclusive procedure for determining whether an alien

may be * * * removed from the United States.” 8 U.S.C. 1229a(a)(3).

Only federal officials acting on behalf of the Secretary may initiate such proceedings.

8 C.F.R. 239.1(a).

Federal law estab-

lishes the grounds on which a noncitizen may be ordered removed,

the requirements for commencing and administering proceedings, and

the procedural protections afforded to noncitizens, see, e.g., 8

U.S.C. 1182(a), 1225, 1227(a), 1228, 1229, 1229a.

Congress also

provided various grounds on which a noncitizen may apply for relief

or protection from removal, including asylum, withholding of removal, and protections under Article 3 of the Convention Against

Torture and Other Cruel, Inhuman, or Degrading Treatment or Punishment (Convention Against Torture or Convention), see, e.g., 8

U.S.C. 1158(a) and (b), 1231(b)(3), 1232; 8 C.F.R. 208.16(c)208.18, 1208.16(c)-1208.18.

The Executive Branch has discretion

to grant various other forms of relief from removal, including

cancellation of removal and adjustment to lawful-permanent-resident status.

See, e.g., 8 U.S.C. 1229b(a) and (b), 1255.

One of the exceptions to the application of formal removal

proceedings is the procedure for expedited removal of certain

8

noncitizens arriving in the United States.

See DHS v. Thuraissi-

giam, 140 S. Ct. 1959, 1964-1966 (2020).

The expedited-removal

procedure authorizes immediate removal of covered noncitizens, but

provides for an interview by a DHS asylum officer and review by an

Immigration Judge if a noncitizen expresses fear of persecution or

the intent to seek asylum.

See 8 U.S.C. 1225(b)(1).

The INA also establishes the method for determining the country to which a noncitizen may be removed.

See 8 U.S.C. 1231 (b).

DHS has the responsibility to work with foreign governments to

determine whether they will accept noncitizens who are subject to

removal orders.

See 8 U.S.C. 1231(b)(1) and (2); 8 C.F.R. 241.15;

see also 8 U.S.C. 1158(a)(2)(A).

And federal law imposes partic-

ular limits on removing a noncitizen to a “foreign territory contiguous to the United States” when the noncitizen is not a “native,

citizen, subject, or national of,” or prior resident of, that

territory.

8 U.S.C. 1231(b)(2)(B).

The INA expressly contemplates several ways in which state

and local officers may assist or cooperate with federal officials

in their enforcement of the INA.

State and local law-enforcement

officers are expressly authorized to make arrests for violations

of the INA’s prohibitions against smuggling, transporting, or harboring noncitizens.

See 8 U.S.C. 1324(c).

Similarly, state and

local officers may (if authorized by state law) arrest and detain

a noncitizen who is illegally present in the United States if the

noncitizen was previously convicted of a felony in the United

9

States and then was deported or left the United States.

1252c.

8 U.S.C.

That express authority is conditioned, however, on receiv-

ing prior confirmation from federal immigration officials of the

noncitizen’s status, and detention may extend no longer than necessary for federal officers to take the noncitizen into custody

for purposes of removal proceedings.

8 U.S.C. 1252c(a).

In ad-

dition, if the Secretary determines that an actual or imminent

mass influx of noncitizens presents urgent circumstances requiring

an immediate federal response, he may authorize any state or local

officer (with the permission of the officer’s agency) to exercise

the authority of federal immigration officers.

See 8 U.S.C.

1103(a)(10).

Congress has also authorized DHS to enter into formal cooperative agreements with States and localities.

8 U.S.C. 1357(g).

Under those agreements, appropriately trained and qualified state

and local officers may perform specified functions of a federal

immigration officer in relation to the investigation, apprehension, or detention of noncitizens.

8 U.S.C. 1357(g)(1)-(9).

The

state officers’ activities under those agreements “shall be subject

to

the

direction

8 U.S.C. 1357(g)(3).2

and

supervision

of

the

[Secretary].”

And even absent such a formal agreement,

the INA provides that state and local officers may “communicate

with the [Secretary] regarding the immigration status of any in-

Section 1357 refers to the Attorney General, but those

functions have been transferred to the Secretary. 6 U.S.C. 251(2).

2

10

dividual,” or “otherwise

* * *

cooperate with the [Secretary] in

the identification, apprehension, detention, or removal of aliens

not lawfully present in the United States.”

2.

8 U.S.C. 1357(g)(10).

Against the backdrop of that comprehensive framework,

Texas adopted its own immigration law, SB4, with an effective date

of March 5, 2024.

Three provisions of SB4 are relevant here.

First, SB4 effectively makes it a state crime for a noncitizen

to violate 8 U.S.C. 1325(a), the INA’s criminal unlawful-entry

provision, by barring noncitizens from “enter[ing] or attempt[ing]

to enter [Texas] directly from a foreign nation at any location

other than a lawful port of entry.”

Tex. Penal Code § 51.02(a).

It is an affirmative defense to violations of that provision if

“the federal government has granted the defendant

presence in the United States” or “asylum.”

* * *

lawful

Id. § 51.02(c).

Vi-

olations of Section 51.02 are Class B misdemeanors, punishable by

fines up to $2000 and 180 days of imprisonment.

51.02(b).

Id. § 12.22,

If a noncitizen has previously been convicted under

that section, a subsequent violation is a felony, punishable by

fines up to $10,000 and 180 days to two years of imprisonment.

Id. § 12.35, 51.02(b).

noncitizens from “enter[ing], attempt[ing] to enter,” or being

“found in” Texas after they have “been denied admission to” the

United States, have been removed from the United States, or have

11

departed the United States while an order of “removal is outstanding.”

Tex. Penal Code § 51.03(a).

SB4 provides no affirmative

defenses for a violation of Section 51.03.

Violations are Class

A misdemeanors, punishable by fines up to $4000 and imprisonment

for up to one year.

Id. § 12.21, 51.03(b).

Third, SB4 allows a state judge to order the removal of a

noncitizen under certain circumstances.

5B.002.

Tex. Code Crim. P. art.

In particular, when a person is charged with offenses

under Section 51.02 or 51.03 but not yet convicted, a state judge

may “discharge the person and require the person to return to the

foreign nation from which the person entered or attempted to enter”

if “the person agrees to the order” and has not “previously been”

charged with or convicted of specific crimes.

Art. 5B.002(a)-(c).

If a noncitizen is convicted under SB4, the state judge “shall

enter” an “order requiring the person to return to the foreign

nation from which the person entered or attempted to enter” after

completion of the state prison sentence.

Art. 5B.002(d).

Texas

law-enforcement personnel must monitor the noncitizen’s compliance

with the state removal order.

Art. 5B.002(e).

Failure to comply

with the order is a second-degree felony. Tex. Penal Code § 51.04.

For any of the offenses created by SB4, the law states that

a “court may not abate the prosecution of [the relevant offense]

on the basis that a federal determination regarding the immigration

status of the defendant is pending or will be initiated.”

Code Crim. P. art. 5B.003.

B.

Proceedings Below

1.

In separate suits, the United States and a set of plain-

tiffs comprising the County of El Paso and two private groups

challenged SB4 in the District Court for the Western District of

Texas.

App., infra, 5a.

The United States and the other plain-

tiffs moved for preliminary injunctions preventing the implementation of SB4, and the district court consolidated the cases.

at 4a.

Id.

In a thorough 114-page opinion, the court granted a pre-

liminary injunction and declined to stay the injunction pending

appeal.

Id. at 3a-116a.

The district court first rejected Texas’s threshold arguments.

App., infra, 12a-31a.

The court held that the private

plaintiffs have standing, id. at 12a-24a; rejected Texas’s contention that certain defendants had sovereign immunity, id. at

24a-26a; held that the United States is entitled to bring a suit

for equitable relief against the State, id. at 27a-29a; and declined to abstain from deciding the motions, id. at 29a-31a.

Turning to the merits, the district court held that the United

States and the private plaintiffs are likely to succeed on the

merits of their claims that SB4 is field preempted, conflict

preempted, and inconsistent with the Foreign Commerce Clause.

App., infra, 31a-67a.

With respect to field preemption, the court

explained that “over a century of Supreme Court cases” recognize

the federal government’s dominant interest in regulating entry and

removal of noncitizens, id. at 32a; that Congress occupied the

13

field by enacting a comprehensive framework governing entry and

removal of noncitizens, see id. at 35a-38a; and that this Court

has squarely rejected state attempts to enact “the sort of ‘concurrent’ criminalization that Texas seeks to impose,” id. at 38a

(quoting Arizona, 567 U.S. at 400).

The district court further held that SB4 conflicts with federal law in numerous respects, including that it “provides state

officials the power to enforce federal law without federal supervision,” App., infra, 56a, “divests federal immigration authorities of the discretion of the enforcement of immigration laws,

which touches on delicate considerations of foreign affairs,” id.

at 57a, “prevent[s] noncitizens from asserting affirmative defenses to removal that would have been available in the federal

system,” ibid., and does not adhere to federal law with respect to

removal destinations, id. at 60a-61a.

With respect to the Foreign Commerce Clause, the district

court held that SB4 facially discriminates against foreign commerce by criminalizing the movement only of noncitizens across an

international boundary and also undermines the federal government’s ability to “speak with one voice in regulating commercial

affairs with foreign states.” App., infra, 66a (citation omitted);

see id. at 64a-67a.

The district court next rejected Texas’s invocation of the

State War Clause.

App., infra, 67a-100a.

That Clause provides

that “[n]o State shall, without the Consent of Congress

* * *

14

engage in War, unless actually invaded, or in such imminent Danger

as will not admit of delay.”

U.S. Const. Art. 1, § 10, Cl. 3.

The court held that “Texas’s argument fails for at least three

reasons”:

“unauthorized immigration does not constitute an ‘in-

vasion’”; “Texas is not ‘engaging in war’ by enforcing SB4 4”; and

even “if Texas were engaging in a war, it would have to abide by

federal directives.”

App., infra, 67a-68a (brackets omitted).

Turning to the remaining preliminary injunction factors, the

district court found that the United States would suffer irreparable harm if SB4 goes into effect.

App., infra, 101a-106a.

And

the court further held that the balance of the equities and public

interest weigh in favor of a preliminary injunction, given the

United States’ sovereign interest in regulating immigration and

Texas’s lack of any legitimate interest in enforcing an unconstitutional law. Id. at 109a-110a. After concluding that “the nature

of SB4 does not lend itself to a partial injunction,” the court

enjoined the law in full.

2.

Id. at 111a.

Respondents appealed to the Fifth Circuit and, shortly

before midnight on March 1, 2024, filed a motion for a stay pending

appeal.

That motion included a one-sentence “request[] [for] an

administrative stay to prevent irreparable harm while the Court

considers this Motion.”

C.A. Stay Mot. 19.

Within hours, the

United States filed a short opposition to respondents’ request for

an administrative stay.

C.A. Doc. 37 (Mar. 2, 2024).

The United

States explained that “[a]n administrative stay ‘in this context

15

. . .

is only intended to preserve the status quo until the

substantive motion for a stay pending appeal can be considered on

the merits.’”

Id. at 2 (quoting Doe #1 v. Trump, 944 F.3d 1222,

1223 (9th Cir. 2019)); see ibid. (collecting similar cases from

other circuits).

Because allowing SB4 to go into effect would

dramatically alter the status quo, the United States argued that

an administrative stay was not warranted.

Id. at 3-4.

The United

States also stated that it intended to file its response to the

motion for a stay pending appeal later on March 2, and that the

court of appeals would then be able to resolve that motion with

the benefit of adversarial briefing before SB4 was set to take

effect on March 5.

Id. at 4.

Early in the evening on March 2, without waiting for that

full response, the court of appeals granted respondents’ motion

for a “temporary administrative stay,” expedited the appeal “to

the next available Oral Argument Calendar,” and deferred consideration of respondents’ motion for a stay pending appeal “to the

oral argument merits panel.”

App., infra, 2a.3 In response to a

This practice of granting what is purportedly “administrative” relief while deferring action on the merits of a stay

motion is increasingly common in the Fifth Circuit and often results in the “administrative” stay remaining in place throughout

the appeal, with the merits panel ultimately denying the underlying

stay motion as moot when it issues a merits opinion. See, e.g.,

Petteway v. Galveston Cnty., No. 23-40582 (Oct. 18, 2023) (granting

administrative stay and deferring stay motion to merits panel,

which affirmed but extended the administrative stay pending an en

banc poll through November 20, 2023); United States v. Abbott, No.

23-50632 (Sept. 11, 2023) (granting administrative stay and deferring stay motion to merits panel, which resolved the appeal on

the merits on December 1, 2023); Missouri v. Biden, No. 23-30445

3

16

request by the plaintiffs in the consolidated case, the court

“stay[ed] the temporary administrative stay for seven days following the date hereof pending an application to the Supreme

Court.”

Ibid.

Judge Ramirez noted that she “would not grant a

temporary administrative stay and would defer the question” to the

merits panel.

Ibid.

Accordingly, absent further action by this Court, the court

of appeals’ stay will take effect at 12:01 a.m. on Sunday, March

10, 2024, thereby allowing enforcement of SB4 for the first time.

The Fifth Circuit has not yet indicated when it will assign the

case to a merits panel or hold oral argument.

ARGUMENT

The United States respectfully requests that this Court vacate the Fifth Circuit’s stay of the district court’s preliminary

injunction.

“The well-established principles” that guide the de-

termination whether “to stay a judgment entered below are equally

applicable when considering an application to vacate a stay.”

Certain Named & Unnamed Non-Citizen Children & Their Parents v.

Texas, 448 U.S. 1327, 1330 (1980) (Powell, J., in chambers).

In

considering such an application, this Court has thus looked to the

traditional “four-factor test” for a stay.

Alabama Ass’n of Real-

(July 14, 2023) (granting administrative stay and deferring stay

motion to merits panel, which resolved the case on the merits on

September 8, 2023); Campaign Legal Ctr. v. Scott, No. 22-50692

(Aug. 12, 2022) (granting an administrative stay and deferring

stay motion to merits panel, which resolved the appeal on the

merits on September 29, 2022).

17

tors v. HHS, 141 S. Ct. 2485, 2488 (2021) (per curiam).

asks:

That test

“(1) whether the stay applicant has made a strong showing

that he is likely to succeed on the merits; (2) whether the applicant will be irreparably injured absent a stay; (3) whether

issuance of the stay will substantially injure the other parties

interested in the proceeding; and (4) where the public interest

lies.”

Nken v. Holder, 556 U.S. 418, 426 (2009) (citation omit-

ted).

Each of those factors strongly supports vacating the stay

in this case.

And vacatur is especially appropriate because the

court of appeals has granted what amounts to a stay pending appeal

without even purporting to consider the relevant factors.

I.

THE GOVERNMENT IS LIKELY TO SUCCEED ON THE MERITS

If the court of appeals overturned the preliminary injunction

in this case, there is a strong likelihood that this Court would

grant a writ of certiorari and reverse.

A decision upholding SB4

would conflict with decisions of other courts of appeals and flout

this Court’s binding precedent on a matter of national importance.

A.

This Court Would Likely Grant Review If The Court Of

Appeals Reversed The Preliminary Injunction

Review in this Court would clearly be in order if the court

of appeals reverses the district court’s injunction.

As the dis-

trict court held, SB4 is plainly preempted under this Court’s

decision in Arizona.

See App., infra, 32a, 38a.

And as the

district court also recognized, see id. at 36a, 49a, 57a, other

courts of appeals have repeatedly upheld injunctions barring en-

18

forcement of other state criminal statutes that purport to replicate federal immigration laws.

lina, 720 F.3d 518, 532-533 (4th Cir. 2013); Valle del Sol Inc. v.

A decision upholding

SB4 would conflict with those decisions.

In addition, the enormous practical and legal consequences of

a decision upholding SB4 would warrant this Court’s review even

absent a square conflict with this Court’s precedents and the

decisions of other courts of appeals.

See, e.g., Biden v. Texas,

597 U.S. 785 (2022) (reviewing, in the absence of any circuit

conflict, a preliminary injunction that interfered with the Executive’s discretionary judgments about whether to return noncitizens to Mexico).

The district court found that SB4 “would imme-

diately disrupt sensitive foreign relations agreements, particularly around the destination for the removal of noncitizens,” and

could “irreparably derail[]” ongoing discussions with Mexico intended “to reduce irregular migration at the southern border.”

App., infra, 102a-103a.

Moreover, Texas’s attempt (C.A. Stay Mot.

15-17) to defend some applications of SB4 as an exercise of the

power to “engage in War” in response to an “inva[sion],” U.S.

Const. Art. I, § 10, Cl. 3, could have far-reaching ramifications

19

under our constitutional structure. See John Yoo, Why Texas Cannot

Treat Illegal Immigration as an ‘Invasion’, National Review (Nov.

18, 2022), https://perma.cc/SB23-KK6Y (“[I]f the border influx

amounts to war,” Texas “could attack drug-cartel members not only

across the border but all the way back to their hideouts.

The

implications for foreign relations are obvious.”).

B.

Federal Law Preempts SB4

The district court also correctly held that the United States

is likely to prevail on the merits of its claim that SB4 is both

field and conflict preempted.

1.

SB4 impermissibly intrudes into a field reserved

to, and occupied by, the federal government

“[T]he States are precluded from regulating conduct in a field

that Congress, acting within its proper authority, has determined

must be regulated by its exclusive governance.”

States, 567 U.S. 387, 399 (2012).

Arizona v. United

Field preemption “can be in-

ferred from a framework of regulation ‘so pervasive

. . .

that

Congress left no room for the States to supplement it’ or where

there is a ‘federal interest

. . .

so dominant that the federal

system will be assumed to preclude enforcement of state laws on

the same subject.’”

Ibid. (citation omitted).

Congress’s enact-

ment of the INA’s comprehensive and detailed regime governing entry

and removal and its vesting of authority in the Executive to administer and enforce all aspects of that regime demonstrate that

federal law fully occupies this field, and the dominant federal

20

interests in this context strongly reinforce that conclusion.

a.

This Court has repeatedly held that the “authority to

control immigration -- to admit or exclude aliens -- is vested

solely in the Federal Government,” Truax v. Raich, 239 U.S. 33, 42

(1915), and that the formulation of “[p]olicies pertaining to the

entry of aliens and their right to remain here

* * *

is entrusted

exclusively to Congress,” Galvan v. Press, 347 U.S. 522, 531 (1954)

(citations omitted).

The allocation of that authority to the

federal government reflects the fundamental proposition that the

United States’ “policy toward aliens is vitally and intricately

interwoven with

* * *

the conduct of foreign relations.”

risiades v. Shaughnessy, 342 U.S. 580, 588-589 (1952).

Ha-

This Court

has long emphasized that “[i]t is fundamental that foreign countries concerned about the status, safety, and security of their

nationals in the United States must be able to confer and communicate on this subject with one national sovereign, not the 50 separate States.”

Arizona, 567 U.S. at 395; see Hines v. Davidowitz,

312 U.S. 52, 66 (1941) (“[T]he regulation of aliens is so intimately blended and intertwined with responsibilities of the national government that where it acts, and the state also acts on

the same subject * * * the law of the State * * * must yield.”).

In recognition of those dominant federal interests and the

National Government’s paramount authority in this area, Congress

enacted the INA, which today comprehensively regulates the entry

and removal of noncitizens.

See Patel v. Garland, 596 U.S. 328,

21

331 (2022) (“Congress has comprehensively detailed the rules by

which noncitizens may enter and live in the United States.

When

noncitizens violate those rules, Congress has provided procedures

for their removal.”).

Congress has determined which noncitizens

may be admitted to the United States and the procedures for their

admission.

8 U.S.C. 1181-1188, 1201-1204.

Congress has provided

“the sole and exclusive procedure for determining whether an alien

may be admitted to the United States or, if the alien has been so

admitted, removed from the United States.”

8 U.S.C. 1229a(a)(3).

Congress has included a detailed process for selecting the countries to which noncitizens may be removed and called upon federal

officials to coordinate with the relevant foreign governments in

executing removal orders.

8 U.S.C. 1231.

Congress has specified

when a noncitizen’s entry into the United States is a crime.

U.S.C. 1325(a) and (b), 1326.

8

And Congress has provided immigra-

tion officers with broad and often unreviewable discretion in exercising the authorities it has vested in them.

Arizona, 567 U.S.

at 396, 409; see Reno v. American-Arab Anti-Discrimination Comm.,

525 U.S. 471, 483-484, 485 n.9 (1999).

Because Congress, in the INA, has thus fully occupied the

field of noncitizen entry and removal, there is “no room for the

States to supplement it,” even through “complementary state regulation.”

Arizona, 567 U.S. at 399, 401.

Texas’s attempt to

supplement federal law through SB4 is therefore preempted.

As the

district court recognized (App., infra, 32a, 38a), that result is

22

compelled by this Court’s holding in Arizona that the doctrine of

field preemption prohibited the State from enacting a criminal

penalty for failure by a noncitizen to comply with the INA’s registration requirements.

See 567 U.S. at 400-403.

Like Arizona,

Texas has attempted to “add[] a state-law penalty for conduct

proscribed by federal law.”

Id. at 400.

Here, as there, “federal

statutory directives provide a full set of standards,” including

“the punishment for noncompliance.”

Id. at 401.

Here, as there,

the statutory framework “was designed as a ‘harmonious whole.’”

Ibid.

And here, as there, “[p]ermitting the State to impose its

own penalties for the federal offenses

Arizona, 567 U.S. at 409;

see Jama v. Immigration & Customs Enforcement, 543 U.S. 335, 348

(2005) (“Removal decisions, including the selection of a removed

alien’s destination, ‘may implicate [the Nation’s] relations with

foreign powers’ and require consideration of ‘changing political

and economic circumstances.’”) (citation omitted).

Allowing “a single State” to make determinations regarding

entry and removal would allow that State “at her pleasure” to

23

“embroil us in disastrous quarrels with other nations.”

Chy Lung

v. Freeman, 92 U.S. 275, 280 (1875); accord Arizona, 467 U.S. at

395.

And if multiple States followed Texas’s example and enacted

their own immigration policies and enforcement measures, the resulting patchwork would cause an even greater interference with

the Nation’s ability to speak with one voice in international

affairs.

See Arizona, 567 U.S. at 395.

It is therefore unsur-

prising that even the dissenting Justices in Arizona did not suggest that States could intrude on federal prerogatives in the way

that SB4 does.

See id. at 427 (Scalia, J., concurring in part and

dissenting in part) (noting that Arizona’s law “does not represent

commencement of the removal process unless the Federal Government

makes it so”); id. at 457 (Alito J., concurring in part and dissenting in part) (emphasizing that under Arizona law “[t]he Executive retains complete discretion over whether [the noncitizens]

are ultimately removed”).

b.

Texas’s contrary arguments are unavailing.

Texas has

attempted (C.A. Stay Mot. 12) to limit Arizona to noncitizen registration.

But while that was the particular field at issue in

Arizona, Texas has provided no reasoned basis for confining the

Court’s analysis to the particular provisions of the INA at issue

there.

And Texas has not shown how SB4’s direct regulation of the

core subjects of entry and removal could withstand field preemption

analysis when the state registration law in Arizona could not.

Texas has also asserted (C.A. Stay Mot. 11-12) that Congress

24

did not preempt the field of entry and removal because federal law

provides certain immigration-related roles for States.

See, e.g.,

18 U.S.C. 758 (creating federal crime of fleeing from federal

immigration checkpoint and from “Federal, State, or local law enforcement agents in excess of the legal speed limit”); 8 U.S.C.

1101(a)(15)(T)(i)(III)(aa) (referencing state “prosecution of acts

of trafficking”).

But none of Texas’s cited laws permits States

to regulate the entry and removal of noncitizens. And Texas simply

ignores Section 1357(g), which expressly allows States to “cooperate with the [Secretary] in the identification, apprehension,

detention, or removal of aliens,” 8 U.S.C. 1357(g)(10)(B) (emphasis added), and thus makes clear that the role of state and local

officials in this area is to assist the Secretary in enforcement

of federal law.

As the district court recognized (App., infra,

63a), that limited provision for States to work hand-in-hand with

the federal government would mean nothing if any State could

“claim[] unlimited concurrent immigration authority.”

Texas also cannot avoid the preemptive force of federal law

by contending that orders under SB4 are not “removals.”

As the

district court explained, Texas’s own declarant stated that SB4

envisions that state officials would “escort[] a noncitizen to the

border” where the noncitizen would “either depart into Mexico or

* * *

face 20 years in prison if they do not.”

App., infra, 45a.

Given that choice, “it is rather absurd to argue” that Texas is

not effectively removing the noncitizens. Ibid. And, as the court

25

recognized (id. at 46a), the fact that the removal is not “in

handcuffs” but only “under threat of handcuffs (and 20 years of

prison)” does not abate the significant foreign affairs concerns

created by a State’s forced return of noncitizens to Mexico outside

of the process Congress specified for the federal government to

identify the countries to which noncitizens may be removed and to

coordinate with foreign governments to determine if they will accept those noncitizens.

2.

See 8 U.S.C. 1231(b).

SB4 conflicts with federal immigration law

SB4 is also preempted because it “stands as an obstacle to

the accomplishment and execution of the full purposes and objectives of Congress.”

a.

Arizona, 567 U.S. at 399 (citation omitted).

It would fundamentally disrupt the federal immigration

regime to allow a single State to make unilateral determinations

regarding unlawful entry and removal.

The enforcement of federal

immigration law necessarily imposes consequences for foreign nationals based on acts committed in violation of federal law and

can involve a sensitive weighing of interests in national security,

border security, foreign affairs, and reciprocal treatment of U.S.

citizens abroad.

See Arizona, 567 U.S. at 395.

Decisions regard-

ing entry and removal thus must take account of the federal government’s foreign relations interests.

Allowing a single State to imprison foreign nationals for

immigration violations or order them removed from the United States

to a non-consenting foreign country without regard to the interests

26

of the Nation as a whole is patently inconsistent with the framework Congress enacted.

Just as there was an impermissible “con-

flict” when a State premised tort liability on fraud committed

against a federal agency due to the “somewhat delicate balance”

that would be “skewed by allowing” such state-law claims, see

Buckman Co. v. Plaintiffs’ Legal Committee, 531 U.S. 341, 348

(2001), so too would SB4 upset the balance Congress struck in

providing for federal enforcement of the immigration laws.

See

Arizona, 567 U.S. at 406 (holding that even though Arizona’s law

“attempts to achieve one of the same goals as federal law,” it

“would interfere with the careful balance struck by Congress”).

In recognition of the necessity of ensuring the Nation speaks

“with one voice” in matters with such significant implications for

foreign affairs, Congress provided for only “limited circumstances

in which state officers may perform the functions of an immigration

officer.”

Arizona, 567 U.S. at 408, 409.

In each of those cir-

cumstances, the state officers are subject to the oversight of

federal officials, who take the lead in fashioning enforcement

priorities and techniques that the state officers must respect.

For example, States may enter into an agreement with DHS to allow

qualified state officers to carry out functions of an immigration

officer “subject to the direction and supervision of the [Secretary],” and only after they have “received adequate training.”

U.S.C. 1357(g)(2)-(3); see Arizona, 567 U.S. at 408-409.

8

Outside

of such formal agreements, state officers may “cooperate with the

27

[Secretary] in the identification, apprehension, detention, or removal of aliens not lawfully present in the United States.”

U.S.C. 1357(g)(10)(B).

8

Such cooperation, for example, could in-

clude participation in a “joint task force with federal officers.”

Arizona, 567 U.S. at 410.

But “no coherent understanding of the

term [‘cooperate’] would incorporate the unilateral decision of

state officers to arrest an alien for being removable absent any

request, approval, or other instruction from the Federal Government.”

Ibid.

SB4 thus conflicts with federal law by “go[ing] far

beyond” the measures contemplated by Congress, “defeating any need

for real cooperation,” and “allow[ing] the State to achieve its

own immigration policy.”

Id. at 408, 410.

The specifics of SB4’s entry and removal provisions further

illustrate its incompatibility with the scheme Congress enacted.

SB4 denies both the federal government and individual noncitizens

access to the INA’s procedures for determining removability, 8

U.S.C. 1225(b) and 1227, and prevents noncitizens from asserting

defenses to removal that would be available in the federal system,

including asylum, see 8 U.S.C. 1158(a)(1), withholding, see 8

U.S.C. 1231(b)(3), and protections under the Convention Against

Torture, see 8 C.F.R. 1208.16(c)(2). Indeed, SB4 expressly rejects

any deference to federal removal proceedings that could result in

a grant of asylum or other relief or protection from removal by

prohibiting a state court from “abat[ing] the prosecution” on “the

basis that a federal determination regarding the immigration sta-

28

tus of the defendant is pending or will be initiated.”

Crim. P. art. 5B.003.

Tex. Code

In so doing, “SB4 plainly conflicts with

federal law by instructing state judges to disregard pending federal defenses.”

App., infra, 58a.

Similarly, SB4 fails to rep-

licate the exemption from the federal prohibition on reentry for

noncitizens who enter with the Secretary’s consent.

See 8 U.S.C.

1326. SB4 thus criminalizes conduct federal law deems permissible.

SB4 also conflicts with federal law because it permits state

judges to order a noncitizen to return to Mexico without following

the federally prescribed process for selecting the country of removal and coordinating with that country.

Under federal law, a

noncitizen who does not enter through a port of entry first must

designate a country of removal, which can be disregarded only in

certain circumstances.

8 U.S.C. 1231(b)(2)(A) and (C).

If the

noncitizen cannot be removed to that country, there is a hierarchy

of removal countries, starting with the noncitizen’s country of

citizenship.

8 U.S.C. 1231(b)(2)(D) and (E).

And the INA places

specific limits on removal to a “foreign territory contiguous to

the United States.”

8 U.S.C. 1231(b)(2)(B).

Accordingly, removal

to Mexico is not permissible in every case under federal law.

Under SB4, however, removal is always “to the foreign nation

from which the person entered” Texas, Tex. Code Crim. P. art.

5B.002(c) and (d) -- that is, Mexico.

That requirement conflicts

with federal law and would “hamper diplomatic discussions regarding immigration with Mexico.”

App., infra, 60a.

Indeed, this

29

Court already recognized that mandating the return of non-Mexican

nationals to Mexico “impose[s] a significant burden upon the Executive’s ability to conduct diplomatic relations with Mexico.”

Biden, 597 U.S. at 806.

Allowing Texas (or other States) to

require that result would impose still greater burdens.

b.

Texas has failed to confront the multiple ways in which

SB4 conflicts with the federal immigration laws. Texas has instead

asserted (C.A. Stay Mot. 14) that a noncitizen can comply with

both SB4 and federal law. But that ignores this Court’s longstanding test for conflict preemption, which is not limited to impossibility.

See, e.g., Hines, 312 U.S. at 67.

Texas has argued (C.A. Stay Mot. 12-13) that even if SB4 is

broader than federal law in some respects, it is valid under this

Court’s reasoning in Kansas v. Garcia, 140 S. Ct. 791, 806 (2020).

But Kansas dealt with state criminal statutes prohibiting “fraud,

forgeries, and identity theft” that applied to “citizens and aliens

alike.”

Id. at 798.

In that context, this Court held that the

State could apply those laws to noncitizens’ use of the identity

of other persons on employment forms, even where such an application overlapped with federal law prohibiting the provision of false

information on the particular form at issue.

Id. at 806-807.

In

so holding, Kansas did not overrule Arizona or authorize States to

enact their own criminal laws governing entry and removal. Rather,

Kansas dealt with a generally applicable law that did not “frustrate[] any federal interests.”

Id. at 806.

Here, by contrast,

30

SB4 specifically targets noncitizens and regulates their entry and

removal in a way that frustrates the INA’s comprehensive scheme

and implicates sensitive issues of foreign relations.

C.

SB4 Violates The Foreign Commerce Clause

SB4 also violates the Foreign Commerce Clause.

That Clause

recognizes that “[f]oreign commerce is preeminently a matter of

national concern.”

Japan Line, Ltd. v. Los Angeles Cnty., 441

U.S. 434, 448 (1979).

And the power to regulate commerce has long

been understood to encompass the power to regulate the movement in

commerce of both persons and commodities. See, e.g., United States

v. Guest, 383 U.S. 745, 758-759 (1966). This Court has thus struck

down state statutes regulating shipmasters bringing foreign passengers to the States under a dormant Foreign Commerce Clause

analysis that reiterated that the “whole subject has been confided

to Congress by the Constitution.”

Henderson v. Mayor of New York,

92 U.S. 259, 274 (1875); see Chy Lung, 92 U.S. at 280.

In assessing state laws implicating foreign commerce rather

than interstate commerce, “a more extensive constitutional inquiry

is required.”

Japan Line, 441 U.S. at 446.

That inquiry is

necessary because if a state law disadvantages foreign nations,

such nations may retaliate “so that the Nation as a whole would

suffer.”

Id. at 450.

Thus, in addition to considering whether

the law discriminates against or unduly burdens foreign commerce,

courts must assess whether the state laws would “prevent[] the

Federal Government from ‘speaking with one voice when regulating

31

commercial relations with foreign governments.’”

Id. at 451.

If

so, the law “is unconstitutional under the Commerce Clause.” Ibid.

SB4 plainly fails that test.

It targets only noncitizens,

criminalizes their movements and orders their removal across an

international border, disrupts the uniformity of the immigration

laws, and prevents the federal government from conveying a unified

message in an area of sensitive foreign affairs.

25-29, supra.

D.

See, pp. 21-23,

SB4 therefore violates the Foreign Commerce Clause.

The State War Clause Does Not Save SB4 From Preemption

Notwithstanding the preemptive effect of federal immigration

law and SB4’s incompatibility with the Foreign Commerce Clause,

Texas has argued that a preliminary injunction is unwarranted “because at least some applications of SB4 are constitutional” under

the State War Clause.

C.A. Stay Mot. 15.

correctly rejected that argument.

1.

The district court

See App., infra, 67a-100a.

With narrow exceptions, the Constitution provides for a

“complete delegation of authority to the Federal Government to

provide for the common defense,” while “divest[ing] the States of

like power.”

Torres v. Texas Dep’t of Pub. Safety, 597 U.S. 580,

590 (2022).

That structure reflects the Founders’ concern that

“‘bordering States

. . .

under the impulse of sudden irritation,

and a quick sense of apparent interest or injury[,]’ might take

action that would undermine foreign relations.”

Arizona, 567 U.S.

at 395 (quoting The Federalist No. 3, at 39 (John Jay) (Clinton

Rossiter ed., 2003)).

To prevent such an occurrence, the State

32

War Clause generally prohibits any State to “engage in War,” U.S.

Const. Art. I, § 10, Cl. 3, leaving decisions about whether and

how war should be waged to the federal government alone.

At a time when communications or troops could take weeks to

travel from one part of the country to another, however, the

Founders recognized the need to account for fast-arising developments to which the federal government had not yet had time to

respond.

Accordingly, the State War Clause carves out from its

general prohibition a narrow exception applicable when a State is

“actually invaded, or in such imminent Danger as will not admit of

delay,” U.S. Const. Art. I, § 10, Cl. 3.

2.

For at least three reasons, the State War Clause and its

“actually invaded” exception do not save SB4 from invalidity.

a.

The exception to the State War Clause applies only where

a State has been “actually invaded” or faces the “imminent” threat

of such “Danger.”

U.S. Const. Art. I, § 10, Cl. 3.

Because Texas

has not been (and is not in imminent danger of being) “actually

invaded,” it cannot invoke that exception.

The original public meaning of the phrase “actually invaded”

indicates that the exception was intended to apply narrowly and is

not triggered by “surges in unauthorized immigration” of the sort

targeted by SB4.

App., infra, 69a.

As the district court thor-

oughly demonstrated, “[c]ontemporary definitions of ‘invasion’ and

‘actually invaded’ as well as common usage of the term in the late

Eighteenth Century predominantly referred to an ‘invasion’ as a

33

hostile and organized military force, too powerful to be dealt

with by ordinary judicial proceedings.”

Id. at 70a; see id. at

71a-75a (surveying contemporaneous dictionaries and usage).

Even if a more expansive understanding of “actually invaded”

were linguistically possible, context confirms that the Founders

used the phrase in a constrained manner.

The State War Clause

reflects an intent generally to prohibit States from “engag[ing]

in War.”

U.S. Const. Art. I, § 10, Cl. 3.

In recognizing an

exception from that prohibition, it was natural for the Founders

to refer to circumstances in which a State’s temporary engaging in

war would be necessary because of the inadequacy of the States’

police powers.

In contrast, there would have been no need to

authorize States to engage in war -- particularly given the risks

that would pose to foreign policy, see The Federalist No. 3, at 39

-- to address circumstances that could be addressed through other

means.

Courts have thus consistently recognized that “invasion”

does not include unlawful immigration.4

b.

Even if Texas could establish that it has been “actually

invaded,” the effect would be to exempt it temporarily from the

See California v. United States, 104 F.3d 1086, 10901091 (9th Cir.) (observing that James Madison described “invasion”

as involving “situations wherein a state is exposed to armed hostility”), cert. denied, 522 U.S. 806 (1997); New Jersey v. United

States, 91 F.3d 463, 468 (3d Cir. 1996) (noting that State identified “no support whatsoever” interpreting “the term ‘invasion’

to mean anything other than a military invasion”); Padavan v.

United States, 82 F.3d 23, 28 (2d Cir. 1996) (holding that “invasion” entails “expos[ure] to armed hostility

* * *

that is

intending to overthrow the state’s government”).

4

34

State War Clause’s general prohibition on “engag[ing] in War.”

U.S. Const. Art. I, § 10, Cl. 3.

It is not that prohibition,

however, that renders SB4 invalid.

Enforcement of SB4 is uncon-

stitutional because it is preempted under the Supremacy Clause and

inconsistent with the Foreign Commerce Clause, not because it

qualifies as prohibited war-making.

Congress in the INA addressed

the circumstances that Texas would characterize as an invasion,

and the State is not free to disregard those provisions.

Texas appears to accept that SB4 is not genuinely “a ‘wartime

measure’” of the sort that would require an exception from the

State War Clause.

C.A. Stay Mot. 17 (quoting App., infra, 88a).

It has argued, however, that “‘the greater power’ to wage war”

necessarily “‘includes the lesser’ power to” enforce SB4.

(quoting Moyer v. Peabody, 212 U.S. 78, 84-85 (1909)).

Ibid.

But as the

district court observed, “Texas is not engaging in war -- through

SB 4 or otherwise -- so it cannot claim that SB 4 is a necessary

domestic component of the war effort.”

c.

App., infra, 89a.

Texas’s reliance on the exception to the State War Clause

also suffers from a third, related flaw.

As indicated by the

reference to “such imminent Danger as will not admit of delay,”

U.S. Const. Art. I, § 10, Cl. 3, “the State War Clause grants

states the power to engage in war for a very limited time before

the federal government can respond,” App., infra, 76a.

But “once

the federal government has had time to respond to the purported

invasion,” id. at 94a, States are not free to contradict the fed-

35

eral government’s considered decision about how (and whether) to

“engage in War” in response to particular circumstances.

Here, Congress has enacted a statute that comprehensively

addresses immigration, including illegal immigration.

And in this

suit, the United States is invoking that statute and seeking to

enjoin Texas’s enforcement of SB4, in part because the State’s

enforcement of SB4 would seriously harm the Nation’s foreign relations.

Under those circumstances, the State War Clause provides

no basis for allowing Texas to enforce SB4 over the United States’

explicit opposition.

See Torres, 597 U.S. at 592 (“The States

ultimately ratified the Constitution knowing that their sovereignty would give way to national military policy.”).

it has brought many similar suits against other States. See, e.g.,

United States v. California, 921 F.3d 865, 875-877 (9th Cir. 2019)

(considering preemption and intergovernmental-immunity challenges

to three California laws); South Carolina, 720 F.3d at 532-533

(affirming injunction barring application of preempted state laws

36

affecting immigration in suit brought by the United States); Alabama, 691 F.3d at 1285-1288 (same).

Those suits reflect a particularly well-settled application

of the principle that the United States may, in appropriate cases,

bring a suit in equity to vindicate the interests of the National

Government under the Constitution.

The canonical precedent rec-

ognizing that authority is In re Debs, 158 U.S. 564 (1895). There,

the United States obtained an injunction against the Pullman rail

strike, which had “forcibly obstructed” interstate commerce.

at 577.

Id.

In recognizing the United States’ authority to seek that

relief, this Court reasoned that “[e]very government, entrusted,

by the very terms of its being, with powers and duties to be

exercised and discharged for the general welfare, has a right to

apply to its own courts for any proper assistance in the exercise

of the one and the discharge of the other.”

Id. at 584.

Contrary to Texas’s argument (C.A. Stay Mot. 9), the rule

applied in Debs is not limited to suits brought “to abate a public

nuisance.”

Rather, Debs endorsed and embodied the “general rule

that the United States may sue to protect its interests.”

Wyan-

dotte Transp. Co. v. United States, 389 U.S. 191, 201 (1967).

Applying that same general rule, subsequent decisions have recognized that when the United States sues in equity to protect other

sovereign interests, such as the United States’ obligation “to

carry out treaty obligations,” “no statute is necessary to authorize the suit.”

Sanitary Dist. v. United States, 266 U.S. 405,

37

425-426 (1925); see, e.g., United States v. American Bell Tel.

Co., 128 U.S. 315, 367-368 (1888) (suit to protect the public from

fraudulent patents); Heckman v. United States, 224 U.S. 413, 438439 (1912) (suit to protect Indian tribes).

Texas identifies no

sound basis for holding that the United States’ sovereign interests

at issue here are any less deserving of protection in equity.5

In addition, the United States may proceed against the officer

defendants under the doctrine of Ex parte Young, 209 U.S. 123, 167

(1908).

A suit against state officials is proper under that doc-

trine where, as here, the plaintiff alleges an imminent or “ongoing

violation of federal law and seeks relief properly characterized

as prospective.”

Virginia Office for Prot. & Advocacy v. Stewart,

563 U.S. 247, 255 (2011) (citation omitted); see Ex parte Young,

209 U.S. at 156 (holding state officers who “threaten” to engage

in “an unconstitutional act

* * *

may be enjoined by a Federal

court of equity from such action”).

Texas has argued that suits

under Ex parte Young “may not be brought by governments” because

the doctrine is purportedly “limited to ‘private parties.’”

Stay Mot. 9 (citation omitted).

C.A.

But this Court has squarely re-

jected that view, holding that “there is no warrant in our cases

for making the validity of an Ex parte Young action turn on the

identity of the plaintiff” and thus allowing such a suit brought

by a government agency to proceed.

Stewart, 563 U.S. at 256.

Indeed, SB4 likely would interfere with the United

States’ compliance with treaty obligations under the Convention

Against Torture. See p. 27, supra; App., infra, 58a-59a.

It would also result in sub-

stantial injuries to the federal government’s interests in avoiding state intrusion into the administration of a statutory scheme

committed to the federal government’s exclusive authority.

To start, SB4 would significantly harm the United States’

relationship with Mexico, the “United States’ largest trading

partner.” App., infra, 103a.

As the district court found, “[t]he

United States engages in regular talks with Mexico to reduce irregular migration at the southern border,” but those “discussions

may become irreparably derailed if SB 4 takes effect.”

Id. at

102a-103a; see D. Ct. Doc. 14-1, at ¶¶ 11-16 (Jan. 12, 2024)

(Jacobstein Decl.) (declaration of senior State Department official regarding anticipated effects of SB4 on the United States’

relationship with Mexico).

Indeed, this Court has recognized that

mandating the return of non-Mexican nationals to Mexico “impose[s]

a significant burden upon the Executive’s ability to conduct diplomatic relations with Mexico.”

Biden, 597 U.S. at 806.

39

Enforcement of SB4 is likely to damage other international

relationships as well.

“It is fundamental that foreign countries

concerned about the status, safety, and security of their nationals

in the United States must be able to confer and communicate on

this subject with one national sovereign, not the 50 separate

States.”

Arizona, 567 U.S. at 395.

By overriding federal control

of “immigration policy,” SB4 would undermine the efficacy of those

communications and create a risk that other nations may respond to

perceived mistreatment in Texas with “harmful reciprocal treatment

of American citizens abroad.”

Ibid.

And because SB4 has no

provision to prevent refoulement (the return of a person to a

country in which she would face persecution or torture), implementation of the law could likely also cause the United States to

violate its treaty obligations. See p. 27, supra; Jacobstein Decl.

¶ 25; App., infra, 106a.

SB4 would also displace federal officers’ exercise of discretion in enforcing the immigration laws, including their choice

between criminal prosecution and removal.

And because SB4 pro-

hibits abatement of a state prosecution while the federal government conducts asylum or adjustment-of-status proceedings, see Tex.

Code Crim. P. art. 5B.003, a noncitizen facing SB4 enforcement

proceedings “would be unable to participate fully in federal immigration proceedings,” “attend scheduled interviews,” or “comply

with required identity and security check procedures.”

Doc. 14-3, at 7 (Jan. 12, 2024).

D. Ct.

Arrests under SB4 would also,

ironically, cause DHS to “lose the ability to pursue expedited

removals, which must be used to remove noncitizens within 14 days

of their arrival.”

App., infra, 105a; see id. at 106a-107a (iden-

tifying additional forms of harm to the United States).

2.

In contrast to the profound harms that enforcement of

SB4 would cause to the United States, Texas would face no cognizable harm from a preliminary injunction that merely maintains the

longstanding status quo while this litigation proceeds.

In its

motion for a stay pending appeal, Texas made a cursory invocation

of “the public’s interest in seeing that laws are enforced.”

Stay Mot. 18.

C.A.

As the district court explained, the preliminary

injunction would leave Texas free to address “‘drug smuggling,

human trafficking, and terrorism’” using the same “expansive police powers

to regulate crime within its borders” that it

has relied on “[f]or the past century.”

All the preliminary injunction does is prevent

Texas from interfering in “the federal field of unlawful entry and

Texas has no valid interest in achieving that disruptive result.
