INTEREST OF THE AMICI CURIAE1

Amici curiae are professors of administrative law,

constitutional law, and related public law subjects at

institutions around the United States. They have

extensive experience studying and teaching the text,

history, and structure of the Constitution, as well

Supreme Court decisions relating to Congress’s legislative powers and the supremacy of federal law. Their

legal expertise thus bears directly on the constitutional issues in this case. Amici share an interest in

the proper application of constitutional limits on

Congress’s authority to enact supreme federal law and

state courts’ obligations to decide properly presented

federal questions.

A full list of amici, who submit this brief in their

individual capacities and not on behalf of their

institutions, appears in the Appendix.

1 Counsel of record for all parties received timely advance notice

INTRODUCTION AND

SUMMARY OF ARGUMENT

The Indian Child Welfare Act (ICWA or the Act)

is a valid exercise of Congress’s authority to enact

supreme federal law that applies in state court proceedings by virtue of the Supremacy Clause. Four

structural principles—each longstanding, and each

relied upon by the political branches—should be

uncontroversial in this case.

First, Congress has the constitutional authority

to enact a statute that implements treaties with Native

Nations and fulfills the U.S.’s unique responsibility to

them. ICWA is just such a statute. In enacting

ICWA, Congress found that its provisions would implement the “Federal responsibility to Indian people,”

including responsibilities arising under treaties between Indian Tribes and the United States. 25 U.S.C.

§ 1901. Thus, Congress exercised what this Court has

called its “broad” constitutional authority over Indian

affairs, which stems from multiple sources and includes

the power to implement Indian treaties. See United

States v. Lara, 541 U.S. 193 (2004).

Since the Founding, Congress has enacted statutes

to implement Indian treaties. This Court has confirmed

Congress’s authority to do so. See, e.g., Worcester v.

Georgia, 31 U.S. (6 Pet.) 515, 561-62 (1832). Nothing

in this Court’s jurisprudence concerning treaties with

foreign nations calls this constitutional authority to

implement Indian treaties into question. To the contrary, this Court has held that Congress may imple-

3

ment a treaty by enacting legislation “as is appropriate to give efficacy to any stipulations which it is competent for the President by and with the advice and

consent of the Senate to insert in a treaty with a

foreign power.” Neely v. Henkel, 180 U.S. 109, 121

(1901); accord Missouri v. Holland, 252 U.S. 416 (1920).

Amici State of Ohio and State of Oklahoma call for this

Court to overrule its precedents concerning foreign

treaties and hold that the Necessary and Proper

Clause does not afford Congress the authority to enact

legislation implementing treaties. Ohio & Okla. Amici

Br. 29. Because, however, Congress relied upon the full

scope of its authority in Indian affairs when enacting

ICWA, this case does not present that question.

Even if it did, this Court has never adopted their

crabbed reading of the Necessary and Proper Clause,

and for good reason: It would radically restrict Congress’s exercise of all of its enumerated powers and

hobble the President’s ability to negotiate treaties with

foreign nations.

Second, Congress has the authority to enact

supreme federal law that state judges must apply

when adjudicating state law causes of action. To hold

otherwise would threaten not only federal statutory

protections for Indian children, but also well-settled

principles of our federal system that stem from the

Supremacy Clause. That Clause provides that federal

law “shall be the supreme Law of the Land; and the

Judges in every State shall be bound thereby, any

Thing in the Constitution or Laws of any State to the

Contrary notwithstanding.” U.S. Const. art.VI, cl. 2.

Congress’s constitutional authority over Indian affairs

authorizes it to enact federal law regulating Indians

that preempts state laws. See Oklahoma v. Castro-

4

Huerta, 142 S.Ct. 2486, 2503 (2022). Yet ICWA’s

challengers and their amici argue that Congress’s

decision to do so through ICWA violates the anticommandeering doctrine.

The anticommandeering doctrine does not exempt

state judges from the Supremacy Clause. In Murphy

v. NCAA, this Court reaffirmed that “federal law is

supreme in case of a conflict with state law.” 138 S.Ct.

1461, 1479 (2018); see New York v. United States, 505

U.S. 144, 178 (1992) (anticommandeering doctrine does

not prohibit Congress from enacting federal “laws

enforceable in state courts”). Where ICWA’s federal

standards concerning the adoption or placement of

Indian children apply, they are binding on state

court judges in child custody proceedings and preempt

conflicting state laws. Contrary to arguments of the

individual plaintiffs and their amici, the anticommandeering doctrine does not extend so far as to permit state judges to ignore binding federal law when

they adjudicate state law causes of action.

Third, Congress has the authority to regulate

state actors through evenhanded laws that confer

rights and impose the same responsibilities on state

actors and private parties alike. In Murphy, this

Court reaffirmed first that a statute does not violate

the anticommandeering doctrine when it “imposes

restrictions or confers rights on private actors,” and,

second, that the anticommandeering doctrine does not

prohibit Congress from regulating state actors

through “evenhanded” regulations that apply to states

and private parties. 138 S.Ct. at 1461, 1480. Under

those principles, ICWA’s rights-conferring, generally

applicable provisions may apply to state child welfare

agencies and private organizations alike.

5

Fourth, the nondelegation doctrine does not prohibit Congress from incorporating another sovereign’s

policy judgments into a federal regulatory scheme.

United States v. Sharpnack, 355 U.S. 286 (1958).

Under this principle, Section 1915(c) of ICWA, which

incorporates Native Nations’ sovereign policy judgments

concerning Indian child welfare, is constitutional. And

even if Section 1915(c) were understood to delegate federal authority, the Supreme Court has unanimously

held that Congress may delegate such authority to

Tribes when, as here, it involves a Tribe’s “internal

and social relations.” United States v. Mazurie, 419 U.S.

544, 557 (1975).

ARGUMENT

I.

C ONGRESS H AS THE P OWER TO E NACT

STATUTES THAT IMPLEMENT TREATIES WITH

NATIVE NATIONS AND FULFILL ITS UNIQUE

RESPONSIBILITY TO THEM

The United States and federally recognized Native

Nations have a unique “government-to-government”

relationship under federal law. See Lara, 541 U.S. at

202. This unique relationship is reflected in the

sources and limits on federal authority in Indian

affairs. Federal authority, while broad, “is subject to

limitations,” including “pertinent constitutional

restrictions” as well as the trust responsibility that

the federal government owes to Native Nations.

United States v. Creek Nation, 295 U.S. 103, 109-110

(1935); see Nell Jessup Newton et al., COHEN ’ S

HANDBOOK OF FEDERAL INDIAN LAW § 5.04[2][a] (2012)

6

(“although congressional power is broad, it is subject

to constitutional limitations”). Congress’s constitutional

authority in Indian affairs arises from a constellation

of explicit constitutional provisions and structural

principles implicit in the Constitution. See Lara, 541

U.S. at 200, 204; Morton v. Mancari, 417 U.S. 535, 552

(1974). Congress may exercise its legislative authority

in order to fulfill its “unique obligation toward the

Indians.” Mancari, 417 U.S. at 541-42, 555; cf. Delaware

Tribal Bus. Comm. v. Weeks, 430 U.S. 73, 83–84 (1977)

(explaining that “the legislative judgment should not

be disturbed ‘[a]s long as the special treatment can be

tied rationally to the fulfillment of Congress’ unique

obligation toward the Indians’” (quoting Mancari, 417

U.S. at 555)).

Just as it had done in countless laws stretching

back to the first Trade and Intercourse Act of 1790,

Congress enacted ICWA based upon its constitutional

authority in Indian affairs and acted to fulfill the

unique “Federal responsibility to Indian people,” which,

it found, is based upon federal “statutes, treaties, and

the general course of dealing with Indian tribes.” See

25 U.S.C. § 1901 (emphasis added). The States of Ohio

and Oklahoma, appearing as amici, suggest that ICWA’s

reference to Indian treaties presents an opportunity

for this Court to overrule its precedent concerning

Congress’s authority to enact statutes that implement

treaties with foreign nations. Ohio & Okla. Amici Br.

29. But this case does not present that question.

7

A. Congress Enacted ICWA Against the

Backdrop of Its Longstanding Practice of

Implementing Indian Treaties and

Fulfilling Its Unique Responsibility to

Indians as Well as This Court’s Repeated

Reaffirmations of Its Authority to Do So

As a matter of history and tradition, there

should be no doubt that Congress has the power to

enact a statute that implements treaties with Native

Nations, fulfills the U.S.’s unique responsibilities to

them, and preempts conflicting state law. Indeed, “for

much of the Nation’s history, treaties, and legislation

made pursuant to those treaties, governed relations

between the Federal Government and the Indian

Tribes.” Lara, 541 U.S. at 201 (emphasis added).

The established practice, beginning with the first

Trade and Intercourse Act of 1790, was for Congress

to enact laws “to effectuate treaty promises of protection” made by the United States to Indian Tribes.

Nell Jessup Newton, Federal Power Over Indians:

Its Sources, Scope, and Limitations, 132 U. PA. L.

REV. 195, 201 (1984). Congress did not confine itself

to implementing specific treaty promises when implementing its duty of protection to Tribes. Instead, the

Trade and Intercourse Acts implemented the unique

federal responsibility owed to all Native Nations, just

as ICWA did two centuries later. As implementing

legislation, the Trade and Intercourse Acts “were not

controversial exercises of congressional power.” Id.

Rather, the Treaty and Necessary Proper Clauses,

together with the Indian Commerce Clause, provided

congressional authority to enact the Trade and Intercourse Acts. See id.; see also United States v. 43

Gallons of Whiskey, 93 U.S. 188, 196–197 (1876) (holding

8

that Congress had authority to implement treaty by

enacting statute criminalizing introduction of liquor

into Indian Country and referring to the treaty power

and the commerce power).

In Worcester v. Georgia, this Court confirmed

that Indian treaties and implementing legislation are

supreme federal law. See 31 U.S. (6 Pet.) at 562.

Worcester held that laws of the State of Georgia were

“void” because they conflicted with federal constitutional law, treaties between the Cherokee Nation and

the U.S., and federal statutes. Id. In particular, the

State’s laws were “in direct hostility with treaties”

between the Cherokee Nation and the U.S., and “in

equal hostility with the acts of congress for regulating

this intercourse, and giving effect to the treaties.” Id.

at 562; see also Castro-Huerta, 142 S.Ct. at 2503 (“a

State’s jurisdiction in Indian country may be

preempted . . . by federal law”).

This Court has repeatedly held that Congress has

authority to enact supreme federal law that implements agreements between Native Nations and the

United States. Even though the U.S. ended the practice

of entering into formal treaties with Native Nations in

1871, Congress has continued to ratify agreements with

them. And this Court has held that such agreementimplementing legislation is supreme federal law under

the Supremacy Clause. See Antoine v. Washington,

420 U.S. 194, 204-05 (1975) (holding that Congress

may “legislate . . . federally protected rights into law”

by “enacting . . . implementing statutes that ratified

an Agreement” between Native Nations and the U.S.).

Against this backdrop, ICWA’s references to

Indian treaties and the unique “Federal responsibility

to Indian people” are unexceptional. 25 U.S.C. § 1901.

9

ICWA protects the rights of children and parents by

allocating jurisdiction over child custody proceedings

among Indian Tribes and the states, providing procedures for custody proceedings in state courts, and

providing for a system of preferences for the placement of Indian children. See, e.g., 25 U.S.C. §§ 1911,

1912, 1915. These federal rights and procedures were

necessary, Congress found, to address widespread bias

in state and private welfare agencies and violations of

the due process rights of Indian children and parents

in state courts, which had led to the “‘wholesale removal

of Indian children from their homes.’” Mississippi

Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 3233 (1989); see 25 U.S.C. §§ 1901-1902; H.R. Rep. No.

95-1386, at 10-12 (1978) (explaining that prior to ICWA,

Indian child welfare decisions in “most cases, [were]

carried out without due process of law”). Redressing

these systemic rights violations, Congress concluded,

would fulfill the federal “responsibility for the protection and preservation of Indian tribes and their

resources[,]” which Congress had “assumed” “through

statutes, treaties, and the general course of dealing

with Indian tribes.” 25 U.S.C. § 1901(2).

B. ICWA Does Not Present an Opportunity

for This Court to Revisit Its Precedent

Concerning Congress’s Authority to

Implement Treaties with Foreign Nations

Seizing upon ICWA’s reference to treaties, amici

Ohio and Oklahoma suggest that this Court should

overrule its precedent concerning Congress’s authority

under the Necessary and Proper Clause to implement

treaties with foreign nations. In particular, the amici

argue that this Court should overrule Missouri v.

Holland to the extent it held that “[i]f the treaty [with

10

a foreign nation] is valid there can be no dispute about

the validity of the [implementing] statute under Article

I, Section 8, as a necessary and proper means to

execute the powers of the Government.” 252 U.S. 416,

432 (1920); see Ohio & Okla. Amici Br. 29. But this is

not a case in which the validity of a federal statute

rests solely upon a treaty and Congress’s authority

to implement it under the Necessary and Proper

Clause. And, therefore, this case does not present the

question that amici Ohio and Oklahoma raise.

The Treaty and Necessary and Proper Clauses

together are a source—but not the only source—of

congressional authority to enact statutes addressing

Indian affairs. The Treaty Clause affords the President

the “Power, by and with the Advice and Consent of the

Senate, to make Treaties,” including treaties with

Indian Tribes. U.S. Const. art. II, § 2, cl. 2. And the

Necessary and Proper Clause, in turn, is one source of

Congress’s power to implement treaties with Native

Nations and fulfill its trust responsibility to them. See

U.S. Const., art. I, § 8, cl. 18; Lara, 541 U.S. at 204.

But so too is the Indian Commerce Clause, to name but

another source of Congress’s authority in Indian

affairs. See 43 Gallons of Whiskey, 93 U.S. at 196-97.

Congress’s constitutional authority in Indian

affairs arises from both constitutional text and

structure. In Mancari, this Court explained, Congress’s

power to legislate with respect to Indian affairs “is

drawn both explicitly and implicitly from the Constitution,” including the Indian Commerce Clause, the

treaty power, and the war power, and may be exercised

to “fulfill[] . . . Congress’ unique obligation toward the

Indians.” 417 U.S. at 551, 555. And in Lara, this Court

reaffirmed that “[t]he Constitution grants Congress

11

broad general powers to legislate in respect to Indian

Tribes” through the Indian Commerce Clause, the

Treaty Clause, and the Necessary and Proper Clause,

not to mention the Property Clause. 541 U.S. at 200,

204.

In enacting ICWA to fulfill the “Federal responsibility to Indian people,” Congress did not rely solely

upon Indian treaties as the source of its constitutional

authority. 25 U.S.C. § 1901. To the contrary, Congress

was explicit in its reliance upon the full scope of its

constitutional authority. It cited the Indian Commerce

Clause as well as “other constitutional authority” to

legislate with respect to Indian affairs. Id. § 1901(1).

And Congress pointed to Indian treaties as well as

statutes and the longstanding “course of dealing”

between Tribes and the U.S. as sources of “the responsibility for the protection and preservation of Indian

tribes and their resources” that it aimed to fulfill with

ICWA. Id. § 1901(2). The U.S. government made treaty

promises to multiple Native Nations to protect the

welfare of Indian children. Matthew L.M. Fletcher &

Wenona T. Singel, Indian Children and Federal-Trust

Trust Relationship, 95 NEBRASKA L. REV. 885, 890

(2017) (discussing the “numerous ratified treaties” in

which the U.S. promised “to guarantee the safety,

education, welfare, and land rights of Indian children”).

Unsurprisingly, therefore, Congress cited Indian

treaties as one—but not the only—basis for ICWA. 25

U.S.C. § 1901(2).

ICWA thus does not present an opportunity for

this Court to revisit Holland. To reach the question

that Ohio and Oklahoma raise, this Court would have

to ignore (or reject) all the other “constitutional

authority” that Congress cited when enacting ICWA.

12

See 25 U.S.C. § 1901(1). And not just that: this Court

would also have to assume that Congress’s authority

to implement Indian treaties has precisely the same

scope (and limits) as its authority to implement foreign

treaties under the Necessary and Proper Clause, notwithstanding the government-to-government relationship and unique “Federal responsibility” that Congress

owes “Indian people.” Id. § 1901.

In any event, “it has long been assumed”—and

was explicitly stated by this Court prior to Holland—

“that Congress can use [its] Necessary and Proper

Clause authority to implement treaties.” Curtis A.

Bradley, Federalism, Treaty Implementation, and

Political Process: Bond v. United States, 108 AM. J.

INT’L L. 486, 488 & n.16 (2014) (citing Neely, 180 U.S.

at 121). In amici’s view, however, the Necessary and

Proper Clause does not furnish Congress with the

authority to implement the U.S.’s commitments under

valid treaties, but only to support the making of

treaties. Ohio & Okla. Amici Br. 30. If adopted, this

rule would hobble the President’s ability to make credible

promises and negotiate treaties with foreign nations.

Amici’s reading of the Necessary and Proper

Clause also would radically restrict Congress’s exercise

of its enumerated powers. As this Court put it in Nat’l

Fed’n of Indep. Bus. v. Sebelius, Congress’s “power to

‘make all Laws which shall be necessary and proper

for carrying into Execution’ the powers enumerated

in the Constitution, Art. I, § 8, cl. 18, vests Congress

with authority to enact provisions ‘incidental to the

[enumerated] power, and conducive to its beneficial

exercise.’” 567 U.S. 519, 559 (2012) (quoting McCulloch

v. Maryland, 17 U.S. (4 Wheat.) 316, 418 (1819)).

McCulloch provided a pertinent example to illustrate

13

what it means for Congress to enact laws “incidental”

to an enumerated power and “conducive to its beneficial

exercise”: Congress has the enumerated power “to

Establish Post Offices and post Roads.” U.S. Const.

art. I, § 8, cl. 7. As Chief Justice Marshall pointed

out in McCulloch, strictly speaking, “[t]his power is

executed, by the single act of making the establishment.” 17 U.S. (4 Wheat.) at 417. But, Chief Justice

Marshall continued, “from [the power of establishing

post offices and post roads] has been inferred the

power and duty of carrying the mail along the postroad, from one post-office to another. And from this

implied power, has again been inferred the right

to punish those who steal letters from the post-office,

or rob the mail.” Id. Those powers might not be

“indispensably necessary to the establishment of a

post-office and post-road.” Id. But, this Court concluded,

they were “indeed essential to the beneficial exercise

of the power.” Id.; see also United States v. Comstock,

560 U.S. 126, 144-45 (2010) (citing this example); id.

at 169 & n.8 (Thomas, J., dissenting) (same). Congress’s

authority to enact statutes implementing valid foreign

treaties is similarly “essential to the beneficial exercise of the power” of the President, with the advice and

consent of the Senate, to make treaties. Thus, amici

have provided no good reason to revisit this Court’s

precedent confirming Congress’s authority to implement treaties.

14

II. THE ANTICOMMANDEERING DOCTRINE DOES NOT

E XEMPT S TATE C OURT J UDGES OR S TATE

AGENCIES FROM APPLYING FEDERAL LAW THAT

CONFERS RIGHTS AND IMPOSES EVENHANDED

REGULATIONS

With ICWA, Congress enacted preemptive federal

law that state court judges must apply and imposed

the same responsibilities upon both state and private

actors when they seek to remove Indian children from

their families. That is not unconstitutional commandeering.

A. Congress Has the Authority to Enact

Supreme Federal Law That State Judges

Must Apply When Adjudicating State Law

Causes of Action

ICWA is a federal law enforceable in state court

child welfare proceedings involving Indian children.

To the extent that it affects the adjudication of a state

law cause of action, ICWA is indistinguishable from

countless federal statutes that this Court and the

lower federal courts have applied in cases involving

state causes of action. On this point, the Supremacy

Clause’s text is clear and admits of no “state law cause

of action” exception to the obligation it imposes on

state judges to apply “the supreme Law of the Land,”

U.S. Const. art. VI, cl. 2. There is no merit to the individual plaintiffs’ argument (Br. 62-68) that the anticommandeering doctrine shields state court judges

from their clear duty under the Supremacy Clause to

apply federal law whenever it applies, including in

cases arising under state law causes of action.

This Court has held that the prohibition on commandeering is implicit in the Tenth Amendment and

15

the federal structure of the Constitution. In New York

v. United States, 505 U.S. at 144, this Court held that

Congress may not command state legislatures to enact

specific legislation. In Murphy, this Court held that

Congress may not command state legislatures to refrain

from enacting legislation either. 138 S.Ct. at 1479.

And in Printz v. United States, 521 U.S. 898, 935

(1997), this Court held that state executives are not

bound by federal commands that they administer federal regulatory programs.

This Court has never held that the anticommandeering doctrine exempts state court judges from

their obligation under the Supremacy Clause to

apply federal laws that may be relevant to the adjudication of state law causes of action. In the area of

family law, for example, this Court has held that federal law may modify the relief available under state

law causes of action. See McCarty v. McCarty, 453

U.S. 210, 235-36 (1981) (holding that federal law preempted state courts from allocating military retirement

pay pursuant to state community property laws upon

divorce); Hisquierdo v. Hisquierdo, 439 U.S. 572, 590

(1979) (holding that federal law preempted state law’s

definition of community property subject to division

with respect to federal pension benefits). In myriad

other areas of law, moreover, federal law may affect

state law causes of action, including by preempting

claims altogether and by requiring specific procedures

before a court may award a particular form of relief.

See, e.g., PLIVA, Inc. v. Mensing, 564 U.S. 604 (2011);

Philip Morris USA v. Williams, 549 U.S. 346, 353

(2007).

The Supremacy Clause leaves no doubt that state

judges have the obligation to apply federal law when

16

such application affects adjudication of a state law

cause of action. Writing for the Court in Printz,

Justice Scalia explained that “the Constitution was

originally understood to permit the imposition of an

obligation on state judges to enforce federal prescriptions, insofar as those prescriptions related to matters

appropriate for the judicial power.” Printz, 521 U.S. at

907 (emphasis in original). This obligation of state

judges was implicit in the Madisonian Compromise,

which “made the creation of lower federal courts optional

with Congress—even though it was obvious that the

Supreme Court alone could not hear all federal cases

throughout the United States.” Id. As the Printz Court

explained, Testa v. Katt, 330 U.S. 386 (1947), spelled

out the implication of this Compromise: “state courts

cannot refuse to apply federal law.” Id. (citing Testa,

330 U.S. at 393). This scheme, which preserves federal

supremacy while permitting Congress to defer matters

of federal law to state courts of competent jurisdiction,

has been a feature of federalism since the Founding.

ICWA contains various federal-law provisions

that the Supremacy Clause requires state court judges

to apply when adjudicating child custody proceedings.

These preemptive federal rules include rights to

petition state courts for relief, see 25 U.S.C. §§ 1914,

1916, 1917; jurisdictional and procedural rules for

adjudicating child custody questions, see id. § 1911,

1912, 1920, 1923; and substantive standards concerning

the best interests of Indian children in placement

proceedings, see id. § 1913, 1915, 1921, 1922. The

anticommandeering doctrine does not exempt state

court judges from their constitutional obligation to

apply these federal rules in cases where they apply.

17

This principle—that the Supremacy Clause

requires state court judges to apply federal law—should

go without saying. Nevertheless, the individual plaintiffs argue that state court judges are free to ignore

the placement preferences in Section 1915 of ICWA.

See Ind. Pls.’ Br. 62-68; see also Goldwater Inst. et al.

Amici Br. 29-30.

The implications of their proposed rule—that the

Supremacy Clause does not require state court judges

to apply federal law when considering a state law

cause of action—are mind-boggling. What would this

rule mean for the Fourteenth Amendment Due Process

Clause’s procedural requirements and limits on punitive

damages awards in state law cases? See Philip Morris,

549 U.S. at 353. That is federal law, and by the logic

of the individual plaintiffs’ reading of the Constitution, a state court judge is free to ignore federal law

when adjudicating a state cause of action. What about

federal statutes that preempt state tort causes of action?

See PLIVA, 564 U.S. at 604. Again, as individual plaintiffs put it, the Supremacy Clause “does not suggest

that a state court considering a state cause of action

must apply federal law.” Ind. Pls.’ Br. 66 (emphasis

omitted).2

2 The individual plaintiffs and their amici identify no principled

distinction between these examples and ICWA, which amici insist

“dictates” to state judges how to enforce state law. Goldwater

Inst. Et al. Amici Br. 29. Yet when federal constitutional law limits

punitive damages—which aim to ensure adequate enforcement

of state law when compensatory damages might be inadequate

to deter future violations—that too “dictates” a decision about

enforcement. So too, federal statutory law “dictates” a decision

about enforcement when it preempts a state law cause of action.

18

Indeed, the individual plaintiffs doubt that Congress can enact federal law that would affect the adjudication of state law medical malpractice cases by

imposing a particular standard of proof. Ind. Pls.’ Br.

66-67. Yet, in fact, Congress has legislated extensively

with respect to state tort law. To pick but one pertinent

example, in the Biomaterials Access Assurance Act of

1998, Congress enacted a set of procedural rules enforceable in state court designed to allow the suppliers of

biomaterials and medical implant component parts to

be dismissed from state law products liability actions.

See 21 U.S.C. § 1603 (1998). Or consider the Y2K

Act, an even more pertinent example, which required

a “clear and convincing evidence” standard of proof

for punitive damages claims in actions stemming from

the anticipated year 2000 computer crashes. 15 U.S.C.

§§ 6601-17 (1999); see Perry H. Apelbaum & Samara

T. Ryder, Third Wave of Federal Tort Reform: Protecting

the Public or Pushing the Constitutional Envelope, 8

C ORNELL J.L. & PUB . P OL ’ Y. 592, 620-627 (1999).

Thankfully, the Y2K disaster did not come to pass,

leaving to another day, or perhaps another millennium,

the question of whether Congress may enact federal

law for tort cases involving systemic computer glitches.

This much is clear, however: the anticommandeering

doctrine does not exempt state judges from their constitutional obligation to apply valid federal law when it

As Judge Dennis discussed below, and the Tribes argue in their

briefing to this Court, the individual plaintiffs’ reading of the

Constitution would eviscerate the enforcement of “a host of federal statutes,” including the Servicemembers Civil Relief Act, 50

U.S.C. § 3911 et seq. See Brackeen v. Haaland, 994 F.3d 249, 318

(5th Cir. 2021). Here, too, the individual plaintiffs have

identified no principled distinction that would limit their sweeping,

proposed exception to the clear dictates of the Supremacy Clause.

19

applies in a case arising under a state law cause of

action.3

B. Congress Has Authority to Regulate State

Actors Through Evenhanded Regulations

That Confer Rights and Impose Corresponding Responsibilities on State and

Private Actors Alike

A statute does not violate the anticommandeering

doctrine when it “imposes restrictions or confers rights

on private actors.” Murphy, 138 S.Ct. at 1480. Moreover,

“[t]he anticommandeering doctrine does not apply

when Congress evenhandedly regulates an activity in

which both States and private actors engage.” Id. Thus,

the anticommandeering doctrine does not shield state

agencies from rights-conferring, generally-applicable

provisions that impose the same responsibilities on

state actors and private parties when they engage in

the same activity.

Several of ICWA’s provisions—including Sections

1912(d), (e), and (f), which the court of appeals majority

struck down on anticommandeering grounds—meet

this criterion. That is, they are generally applicable

provisions that confer rights on Indian children and

parents and impose corresponding responsibilities

upon state agencies and private actors alike. Texas

3 The individual plaintiffs cite Professor Evan Caminker’s work

in support of their proposed rule, see Ind. Pls.’ Br. 64-65, but omit

his most relevant conclusion: “a state court may not entertain

and adjudicate causes of action arising under state law in a

manner that would conflict with applicable federal law.” Evan H.

Caminker, State Sovereignty and Subordinancy: May Congress

Commander State Officers to Implement Federal Law?, 95

COLUM. L. REV. 1001, 1023 (1995).

20

concedes (Br. 68) that “several of ICWA’s provisions

apply to any party initiating a child-custody proceeding, see, e.g., 25 U.S.C. §§ 1912, 1915“—that is, these

provisions are generally applicable regulations of an

activity that both state and private actors engage in,

namely, petitioning for the removal of Indian children

from their families. Nevertheless, Texas argues, these

statutory provisions are unconstitutional commandeering because the state has a sovereign interest at

stake in that activity and because the activity does not

involve marketplace competition. Texas Br. 65-69; see

also Academy & NCFA Amici Br. 9. This proposed

“marketplace-competition-only” rule supposedly stems

from this Court’s opinions in Murphy and Reno v.

Condon. See Texas Br. 68-69; Academy & NCFA Amici

Br. 11-12.

Under those precedents, however, Congress may

enact rights-conferring provisions that preempt state

law and impose evenhanded regulations on state and

private actors alike. ICWA is both a rights-conferring

provision and an evenhanded regulation. As to the

evenhanded-regulation rule, Murphy said that it

“formed the basis for the Court’s decision” in Reno v.

Condon, “which concerned a federal law restricting

the disclosure and dissemination of personal information provided in applications for driver’s licenses.”

Murphy, 138 S.Ct. at 1478-79. As this Court explained,

“[t]he law applied equally to state and private actors.

It did not regulate the States’ sovereign authority to

‘regulate their own citizens.’” 138 S.Ct. at 79 (quoting

Reno, 528 U.S. at 151). The Court did not say that

marketplace competition is the only type of activity in

which both States and private actors may engage.

Nor did it say that Congress commandeers the States

21

whenever it regulates an activity in which the states

have a sovereign interest. Instead, this Court implied

that a law “regulated[ing] the States’ sovereign

authority to ‘regulate their own citizens’” would not

be an evenhanded regulation. Id.

ICWA does not commandeer the States by regulating their sovereign authority to regulate their own

citizens. Sections 1912 and 1915 of ICWA contain

rights-conferring provisions that validly preempt

conflicting state law. Moreover, these rights-conferring

provisions impose corresponding and evenhanded responsibilities upon state and private actors. Sections 1912

and 1915 do not “commandeer[] the state legislative

process.” Murphy, 138 S.Ct. at 1479. They do not

“direct[] the States either to enact or to refrain from

enacting a regulation of activities occurring within

their borders.” Id. Nor do they “command” a state

actor “to administer or enforce a federal regulatory

program.” Printz, 521 U.S. at 935. Thus, these provisions do not “regulate the States’ sovereign authority

to ‘regulate their own citizens.’” Murphy, 138 S.Ct. at

1479.

1. Sections 1912 and 1915 of ICWA contain

rights-conferring provisions that do not

commandeer the States

In Murphy, this Court held that the Professional

and Amateur Sports Protection Act (PASPA) unconstitutionally commandeered the states by making it unlawful for a state to “authorize” sports gambling. See 138

S.Ct. at 1468 (quoting PASPA, 28 U.S.C. § 3702(1));

id. at 1478 (holding that PASPA’s prohibition violated

the anticommandeering rule). Prohibiting a state from

enacting new legislation authorizing sports gambling

22

was indistinguishable from requiring a state to enact

legislation, which New York held was unconstitutional commandeering. See id. at 1478; New York, 505

U.S. at 176-177. Thus, Murphy was concerned with

limiting Congress’s power to compel state governments to maintain existing laws on the books, not

with upsetting the longstanding principle that state

governments may not enforce state policies that

conflict with (and thus are preempted by) federal law.

Murphy distinguished PASPA’s bare command to

state governments from federal statutes that regulate

and confer rights upon private parties. This Court

explained that “every form of preemption is based

upon a federal law that regulates the conduct of private

actors, not the States.” 138 S.Ct. at 1481. The challenged provision of PASPA was “not a preemption

provision because there [was] no way in which this

provision [could] be understood as a regulation of

private actors.” Id. It did not “confer any federal rights

on private actors,” nor did “it impose any federal

restrictions on private actors.” Id. A private actor

could open a gambling business without violating the

PASPA provision because that provision was directed

only at the states. See id. As a result, “there [was]

simply no way to understand the provision prohibiting

state authorization as anything other than a direct

command to the States.” Id.

Unlike PASPA, ICWA is not a direct command to

a state legislature to refrain from legislating or to

maintain existing laws. Nor is it a command to state

agencies. Rather, Sections 1912 and 1915, which the

court of appeals majority struck down in part on

anticommandeering grounds, contain various provisions

conferring rights on Indian children and parents and

23

imposing corresponding responsibilities on state and

private actors. Section 1912(a), for example, requires

“the party seeking the foster care placement of, or

termination of parental rights to, an Indian child [to]

notify the parent or Indian custodian and the Indian

child’s Tribe,” thus guaranteeing a federal right to

notice. 25 U.S.C. § 1912(a). Section 1912(d) similarly

confers rights by specifying that any party—whether

a state agency or private organization—must “satisfy

the court that active efforts have been made . . . to

prevent the breakup of the Indian family” before the

court may order a foster care placement or terminate

parental rights at that party’s request. Id. § 1912(d).

Section 1912(e) and (f) confer rights to “continued

custody” of an Indian child unless the opposing party

produces evidence, “including testimony of qualified

expert witnesses,” sufficient to show it is “likely” that

“continued custody” would “result in serious emotional

or physical damage to the child.” Id. § 1912(e)-(f). And

Section 1915(a)-(b) confers rights by establishing a

default set of placement preferences, which, when they

apply, must be followed in the absence of a showing of

“good cause to the contrary.” Id. § 1915(a)-(b). These

provisions are not direct commands “to administer or

enforce a federal program.” Printz, 521 U.S. at 935.

There is simply no way to understand these provisions

as anything other than rights-creating, which, presumably, is why Section 1921 of ICWA refers to “the rights

provided under this subchapter.” 25 U.S.C. § 1921.

2. Sections 1912 and 1915 of ICWA contain

evenhanded regulations that do not

commandeer the States

Congress imposed responsibilities upon both state

and private actors in Section 1912 and Section 1915

24

because both may engage in the same activity: seeking

to initiate child-custody proceedings involving Indian

children. See generally Matter of Adoption of B.B., 417

P.3d 1, 28 (Utah 2017) (concluding that Indian parent

had rights under ICWA in case involving private

agency). To the extent that it creates rights and imposes

corresponding responsibilities upon state agencies

and private organizations alike, ICWA is analogous to

the Driver’s Privacy Protection Act (DPPA), which this

Court unanimously upheld in Reno v. Condon, see 528

U.S. 141 (2000), a decision reaffirmed by this Court in

Murphy, 138 U.S. at 1478. The DPPA prohibited state

departments of motor vehicles from releasing a driver’s

personal information without the driver’s consent.

This prohibition also applied to private entities. This

Court concluded that the DPPA’s “generally applicable”

regulations did not commandeer state activities. Id. at

1478 (citing South Carolina v. Baker, 485 U.S. 505,

514-15 (1988)).

Like the DPPA, subchapter I of ICWA includes

provisions that regulate both state agencies and

private entities. For example, Section 1912(a) requires

“the party seeking the foster care placement of, or

termination of parental rights to, an Indian child [to]

notify the parent or Indian custodian and the Indian

child’s Tribe.” 25 U.S.C. § 1912(a). Section 1912(d)

similarly regulates any party—whether a state agency

or private organization—by requiring them to “satisfy

the court that active efforts have been made . . . to

prevent the breakup of the Indian family” before the

court may order a foster care placement or terminate

parental rights at that party’s request. Id. § 1912(d).

Subsections (e) & (f) of Section 1912 similarly apply

evenhandedly, as do the placement preferences of

25

Section 1915(a)-(b). These are valid preconditions to a

state court’s issuing an order concerning the placement

of an Indian child. And they are valid, generally

applicable regulations of a state’s activities. Just as

Congress could constitutionally regulate state departments of motor vehicles through the DPPA, so too may

it regulate state child welfare agencies through the

generally applicable provisions of ICWA. ICWA, in

other words, is not commandeering but rather an

evenhanded regulation of “an activity in which both

States and private actors engage.” Murphy, 138 S.Ct.

at 1478.

III. CONGRESS HAS THE AUTHORITY TO INCORPORATE

ANOTHER SOVEREIGN’S POLICY JUDGMENTS INTO

THE IMPLEMENTATION OF A FEDERAL REGULATORY

SCHEME

One of Congress’s goals in enacting ICWA was

the “placement of such children in foster or adoptive

homes which will reflect the unique values of Indian

culture.” 25 U.S.C. § 1902. To accomplish this goal,

Congress prospectively incorporated Native Nation’s

policy judgments into implementation of ICWA’s placement preferences. Sections 1915(a)-(b) contain default

placement preferences. Id. § 1915(a)-(b). Section 1915(c)

provides that if “the Indian child’s tribe” establishes

placement preferences, “the agency or court effecting

the placement shall follow such order so long as the

placement is the least restrictive setting appropriate

to the particular needs of the child.” Id. § 1915(c). It

also provides that “[w]here appropriate, the preference of the Indian child or parent shall be considered.”

Id.

The Fifth Circuit correctly held that Section 1915(c)

“validly integrates tribal sovereigns’ decision-making

26

into federal law” and thus “does not violate the nondelegation doctrine.” Brackeen v. Haaland, 994 F.3d

249, 352 (5th Cir. 2021).

A. Congress’s Incorporation of Another

Sovereign’s Laws into Federal Law Is Not

an Unconstitutional Delegation of Congress’s

Legislative Authority

ICWA’s prospective incorporation of Tribal

policymaking into federal law is not unusual. Congress

has enacted various federal statutes that adopt state

law not only as it is at the time of enactment, but also

as it may be in the future at the time of the statute’s

application in a particular case. See Joshua M. Divine,

Statutory Federalism and Criminal Law, 106 VA. L.

REV. 127, 138-143 (2020) (providing examples); Michael

C. Dorf, Dynamic Incorporation of Foreign Law, 157

U. PA. L. REV. 103, 125-26 (2008) (same).

This Court has held Congress does not unconstitutionally delegate legislative power simply by incorporating state law into federal law. In Gibbons v. Ogden,

22 U.S. (9 Wheat.) 1, 207 (1824), this Court stated

that “Congress may adopt the provisions of a State

on any subject.” And in United States v. Sharpnack,

this Court held that Congress has the authority prospectively to incorporate state law. 355 U.S. 286

(1958). In Sharpnack, the Supreme Court upheld the

Assimilative Crimes Act (ACA), a federal statute that

incorporated states’ criminal laws “in force at the

time” of the alleged crime and made them applicable

in federal enclaves within each state. Id. The Court

held that the law was a “deliberate continuing adoption

by Congress” of state law as binding federal law, with

Congress retaining the legislative authority “to exclude

27

a particular state law from the assimilative effect of

the Act.” Id. at 294; see also Gibbons, 9 U.S. (Wheat.)

at 207. Rather than an impermissible delegation of

Congress’s legislative power, the prospective adoption

of state law as federal law was viewed as a “practical

accommodation of the mechanics of the legislative

functions of State and Nation.” Sharpnack, 355 U.S.

at 294.

In this respect, Section 1915(c) of ICWA is

indistinguishable from the ACA. Just as the ACA

incorporates state criminal laws, so too does Section

1915(c) incorporate Tribal laws concerning Indian

children, a matter in which Tribes have sovereign

authority. See Holyfield, 490 U.S. at 42 (tribal authority

“over Indian child custody proceedings is not a novelty

of the ICWA,” but a component of tribal sovereignty);

cf. Denezpi v. United States, 142 S.Ct. 1838, 1850

(2022) (Gorsuch, J., dissenting) (recognizing that federal law might “assimilate tribal crimes”). And like

the ACA, ICWA does not purport to preclude Congress

from withdrawing its adoption of another sovereign’s

law if it decides to do so. As such, Section 1915(c) is a

“deliberate continuing adoption by Congress” of tribal

law into federal law. See Sharpnack, 355 U.S. at 293-94.

B. ICWA Contains Intelligible Principles to

Guide the Implementation of Placement

Preferences by States and Tribes

Even if Section 1915(c) constituted a delegation

of federal authority to Tribes, Congress can make (and

repeatedly has made) such delegations, limited only

by the requirement that the statute in question set

forth an “intelligible principle” governing the delegee’s

discretion. See Whitman v. Am. Trucking Ass’ns, 531

28

U.S. 457, 474 (2001). So long as Congress provides an

“intelligible principle” to govern its delegation of

authority, the recipient of the delegated power is not

exercising “legislative power.” J.W. Hampton, Jr. &

Co., 276 U.S. 394, 409 (1928).

Section 1915 plainly specifies intelligible principles

to govern the placement of an Indian child. Section

1915(c) merely recognizes tribal authority to change

the order of a congressionally established list of child

placement preferences already outlined in Sections

1915(a)-(b). And though Section 1915(c) provides that

an Indian Tribe’s decision may reorder the placement

preferences, a state agency or court must also consider

additional statutory factors bearing upon the placement

decision. If a Tribe “establish[es] a different order” of

placement preferences, then Section 1915(c) directs a

court in a child custody proceeding to follow that

reordered list, but only if the placement would be “the

least restrictive setting appropriate to the particular

needs of the child.” 25 U.S.C. § 1915(c). The statute

further specifies that, “[w]here appropriate, the preference of the Indian child or parent shall be considered.”

Id. The guidance to Tribes and States in Section 1915

is more than enough to satisfy the nondelegation

doctrine’s intelligible principle requirement. See Whitman, 531 U.S. at 474 (direction to regulate in the

“public interest” suffices).

C. The Private Nondelegation Doctrine Does

Not Apply in This Case

Texas and amicus New Civil Liberties Alliance

(“NCLA”) contend that Section 1915’s incorporation of

Indian Tribal placement preferences violates the

private nondelegation doctrine because Indian Tribes

29

are not part of the federal government. See Texas Br.

72-73; NCLA Br. 20-23 (both citing Carter v. Carter

Coal Co., 298 U.S. 238 (1936)). This argument is

squarely foreclosed by this Court’s precedent and

would radically undermine a variety of cooperative

regulatory schemes that include both Tribes and States

in their implementation. See, e.g., Arizona Pub. Serv.

Co. v. EPA, 211 F.3d 1280, 1288 (D.C. Cir. 2000) (noting

that the Clean Air Act expressly delegates regulation

of air quality to Tribes); City of Albuquerque v.

Browner, 97 F.3d 415, 424 (10th Cir. 1996) (holding

that EPA had authority to require upstream dischargers

to comply with Pueblo of Isleta’s limitations even if

those limitations were more stringent than federal

standards); Wisconsin v. EPA, 266 F.3d 741, 748 (7th

Cir. 2001) (concluding that under the Clean Water Act,

EPA may authorize Tribes to regulate off-reservation

discharges).

Native Nations are sovereign governments with

authority to “make their own laws and be ruled by

them.” Williams v. Lee, 358 U.S. 217, 220 (1959). One

of the fundamental attributes of a Native Nation’s

sovereignty is the authority to preside over internal

relations and matters involving tribal members,

especially in the areas of family law and the welfare

of Indian children. See, e.g., Holyfield, 480 U.S. at 42.

Tribes’ exercise of these core self-governance functions

“has never been taken away from them, either explicitly

or implicitly, and is attributable in no way to any

delegation to them of federal authority.” United States

v. Wheeler, 435 U.S. 313, 328 (1978). To hold that

Indian Tribes are subject to the private nondelegation

doctrine would be to ignore two centuries of federal

practice and this Court’s precedent. See, e.g., Worcester

30

31 U.S. (6 Pet.) at 542-43; Williams, 358 U.S. at 220;

Holyfield, 480 U.S at 42.

In Mazurie, this Court expressly rejected the

argument that an Indian Tribe is indistinguishable

from a private entity and therefore cannot exercise

governmental power in implementing a federal

regulatory scheme. Writing for a unanimous Court,

Justice Rehnquist rejected a constitutional challenge

to 18 U.S.C. § 1161, which authorized Indian Tribes

to regulate the introduction of liquor into Indian

country. Mazurie, 419 U.S. at 547; Rice v. Rehner, 463

U.S. 713, 728-29 (1983) (reaffirming Mazurie). In

particular, this Court rejected the court of appeals’

conclusion that the private nondelegation doctrine

applied to delegations to Native Nations. See Mazurie,

419 U.S. at 556 (internal quotation marks omitted).

As the Court reasoned, “it is an important aspect of

this case that Indian Tribes are unique aggregations

possessing attributes of sovereignty over both their

members and their territory” and thus “possess[]

independent authority over the subject matter.” Id. at

556-57.

Like 18 U.S.C. § 1161, Section 1915(c) of ICWA is

constitutional. ICWA concerns the “internal and

social relations of tribal life,” namely the rights of

Indian children and parents. See Mazurie, 419 U.S. at

557; Fisher v. District Court, 424 U.S. 382, 388 (1976).

Section 1915(c) recognizes that Native Nations have

“independent authority over” child custody matters

and the rights of Indian children and includes them to

in a federal scheme addressing matters of Tribal concern. See Mazurie, 419 U.S. at 556-57. It does not violate

the nondelegation doctrine.

CONCLUSION

ICWA is supreme federal law that applies in state

court proceedings under longstanding and uncontroversial principles of structural constitutional law.
