INTRODUCTION AND

SUMMARY OF ARGUMENT

This amicus brief addresses the obligation of U.S.

courts to construe federal statutes, including the

Immigration and Nationality Act (“INA”), in a manner

consistent with the nation’s obligations under binding

international treaties. This has been an established

canon of statutory construction since Murray v. The

Schooner Charming Betsy, 6 U.S. (2 Cranch) 64

(1804). Applying that canon here, this Court should

avoid an interpretation of the INA that allows for

detention

without

a

prompt

individualized

determination by a court, independent of the

detaining authorities and capable of ordering release,

that detention is reasonable, necessary and

proportionate under the facts of the particular case.

Pursuant to treaties, such as the International

Covenant on Civil and Political Rights (“ICCPR”), the

United States must protect individuals’ right to

liberty. It may not arbitrarily detain any person and

must provide certain safeguards against arbitrary

detention.

These protections, as well as those

contained in the United Nations Convention Relating

to the Status of Refugees (“Refugee Convention”) and

its Protocol, apply to individuals seeking refugee

protection held in U.S. immigration detention. In

5

particular, the United States must provide for prompt

review by a court of each individual’s detention, and

continuing detention must be subject to periodic

review. The Government must show the reviewing

court that the particular individual’s detention is, and

remains, reasonable, necessary and proportionate in

the circumstances of the individual’s case.

The Government’s interpretation of the INA

cannot be squared with U.S. treaty obligations under

international law. According to the Government, the

INA authorizes the detention of those seeking refugee

protection while denying them access to an

individualized immigration court custody hearing.

The Government’s interpretation, in short, would

deny to many individuals seeking refugee protection,

including families with children, the rights and

safeguards the United States is obligated to provide

under the ICCPR and other international treaties.

Further, detention impedes access to refugee

protection and increases the risk that individuals with

bona fide claims will abandon their cases, thus

undermining the United States’ compliance with the

principle of non-refoulement, which prohibits states

from returning refugees to countries where they may

be at risk of torture or persecution.

These considerations provide further reason why

this Court should reject the Government’s

construction of the INA and affirm the Court of

Appeals’ decision.2

Respondents’ brief invokes the canon of statutory

interpretation that a statute be interpreted, where possible, to

avoid potential constitutional concerns, and explains how the

INA should be construed to satisfy this principle.

I.

The INA Should Be Interpreted Consistently

with U.S. Treaty Obligations

Since the earliest days of the republic, this Court

has recognized that domestic statutes must be read in

light of this nation’s binding international treaty

obligations. See, e.g., Talbot v. Seeman, 5 U.S. (1

Cranch) 1, 43 (1801). “It has been a maxim of

statutory construction since the decision in

[Charming Betsy] that an act of congress ought never

to be construed to violate the law of nations, if any

other possible construction remains.” Weinberger v.

Rossi, 456 U.S. 25, 32 (1982) (internal quotation

marks omitted); accord F. Hoffmann-La Roche Ltd v.

Empagran S.A., 542 U.S. 155, 164 (2004); Sale v.

Haitian Ctrs. Council, 509 U.S. 155, 178 n.35 (1993);

Restatement (Third) of the Foreign Relations Law of

the United States § 114 (1987) [hereinafter

Restatement (Third)].

The United States is bound by the international

treaties to which it is a party. Restatement (Third)

§ 102. Under Charming Betsy and its progeny, this

Court must consider these sources of authority when

interpreting statutes that implicate the Government’s

obligations under international law. See Chew Heong

v. United States, 112 U.S. 536, 539-40 (1884)

(interpreting a statute so as not to violate terms of

treaty); Charming Betsy, 2 Cranch at 118

(interpreting a statute so as not to violate “the law of

nations”).

This Court has applied the Charming Betsy

doctrine for over two hundred years in a wide variety

of contexts. See, e.g., Weinberger, 456 U.S. at 32 (“We

think that some affirmative expression of

7

congressional intent to abrogate the United States’

international obligations is required in order to

construe” a statute as undermining international

agreements); Trans World Airlines, Inc. v. Franklin

Mint Corp., 466 U.S. 243, 251-53 (1984) (holding that

Warsaw Convention provisions were enforceable

despite a later conflicting statutory enactment, in part

because of considerations of international law);

United States v. Forty-Three Gallons of Whisky, 108

U.S. 491, 496 (1883) (“The laws of Congress are

always to be construed so as to conform to the

provisions of a treaty, if it be possible to do so.”); Clark

Sociedad Nacional de Marineros de Honduras, 372

U.S. 10, 21 (1963);Chew Heong, 112 U.S. at 549.

This Court should thus avoid an interpretation of

the INA that would violate the Government’s treaty

obligations under international law.

II.

U.S. Treaty Obligations Prohibit Mandatory

Detention Without Case-by-Case Assessment

The Government’s practice of detaining noncitizens under 8 U.S.C. § 1231 without access to

immigration court review of their detention is at odds

with the ICCPR, a multilateral treaty that the United

States ratified without relevant reservation. See

International Covenant on Civil and Political Rights,

Dec. 16, 1966, 999 U.N.T.S. 171 [hereinafter ICCPR];

138 Cong. Rec. 8070-71 (1992). As discussed below,

Article 9(1) of the ICCPR prohibits “arbitrary arrest

or detention.” In addition, Article 9(4) of the ICCPR

provides that anyone deprived of liberty by arrest or

detention “shall be entitled to take proceedings before

a court.” Pursuant to executive order, it is the

8

Government’s “policy and practice . . . fully to respect

and implement its obligations under the international

human rights treaties to which it is a party, including

the ICCPR.” Implementation of Human Rights

Treaties, Executive Order No. 13107, 63 Fed. Reg.

68,991 (Dec. 10, 1998).3 The U.N. Human Rights

Committee has specifically expressed concern that the

United States’ use of mandatory detention that

results in non-citizens being detained “without regard

to the individual case” raises concerns under Article 9

of the ICCPR.

(“Refugee Protocol”). See United Nations Protocol

Relating to the Status of Refugees art. 1 ¶ 1, Jan. 31,

1967, 606 U.N.T.S. 267 [hereinafter Refugee

provides in Article XXV that “[e]very individual who

infra, international treaties—including the ICCPR

and Torture Convention—afford migrant children

special protections and restrict their immigrationbased detention.

Consistent with U.S. treaty obligations, the United

States may detain a person only after establishing, on

a case-by-case basis, that detention is reasonable,

necessary and proportionate under the particular

individual’s circumstances. Detention is only

permitted as a measure of last resort.

The

Government’s position runs counter to these

obligations.

A.

The Government Must Provide for an

Individualized Determination That a

Non-Citizen’s Detention Is Reasonable,

Necessary and Proportionate

The Government’s interpretation of the INA is at

odds with the United States’ obligation to assess on a

case-by-case basis whether an individual’s detention

is reasonable, necessary and proportionate.

Article 9(1) of the ICCPR provides that every

person “has the right to liberty” and “[n]o one shall be

subjected to arbitrary arrest or detention.” ICCPR

art. 9(1) (emphasis added). The American Declaration

similarly provides that all persons have the right to

liberty and that unlawful or arbitrary detention is

prohibited. American Declaration arts. I, XXV. The

i. Mandatory Detention Is an Impermissible

Penalty and Restriction on Movement of

Refugees

The Government’s interpretation of the INA also

conflicts with the United States’ obligation under the

Refugee Convention to avoid unnecessary restrictions

on the movement of individuals seeking refugee

protection and to avoid punishing such persons for

their unlawful entry or presence.

Mandatory detention—applied without regard to

reasonableness, necessity or proportionality—serves

no governmental purpose other than to punish those

seeking refuge in the United States. Such arbitrary,

punitive detention amounts to an unlawful penalty

under international law. See, e.g., UNHCR Detention

Guidelines, ¶ 32 (explaining that “detention for the

sole reason that the person is seeking asylum”

constitutes a “penalty . . . in violation of international

law”); see also Refugee Convention art. 31(2)

(prohibiting contracting states from imposing

restrictions on the movements of refugees “other than

those which are necessary”); UNHCR Detention

The Refugee Convention specifically prohibits the

use of detention as a penalty or sanction for illegal

entry or presence in a country where refuge is sought.

See UNHCR Detention Guidelines, ¶¶ 11, 14, 32,

48(iii) (“Detention of asylum-seekers for immigrationrelated reasons should not be punitive in nature.”);

(2001) [hereinafter Goodwin-Gill] (penalizing those

viewed as illegal entrants without regard to the

circumstances of flight in each individual case

amounts to a breach of state’s obligation).

In this case, the Government seeks to detain those

who seek refugee protection for the duration of their

immigration proceedings due to the manner of their

entry and without allowing an immigration court to

review their detention. The U.N. Working Group on

Arbitrary Detention has specifically expressed

concern regarding the United States’ detention of

immigrants subject to mandatory detention. Upon

17

visiting the United States, the Working Group

observed that immigrants in U.S. “holding facilities .

. . were subject to mandatory detention under punitive

conditions that were often indistinguishable from

those applicable to persons who had been sentenced to

punishment in the criminal justice system.” U.N.

many cases, . . . unreasonably long, unnecessary,

[and] . . . carried out in degrading conditions.” Id.

¶ 87. Mandatory detention substantially increases

the likelihood that individuals seeking refugee

protection will be subjected to such unlawful

treatment.

ii. Detention as a Method of Deterrence Is

Impermissible

International law likewise prohibits the use of

detention as a method of deterring unlawful entry or

presence of persons seeking international protection.

A.C. Helton, Detention of Refugees and Asylum

Seekers, in Loescher, G. & Monahan, L., “Refugee

Issues in International Relations,” Oxford (1989)

punishment, in that it deprives a person of their

liberty for no other reason than their having been

forced into exile . . . .”); U.N. Working Grp. on

deprivation of liberty of migrants, ¶¶ 21-22, U.N. Doc.

A/HRC/39/45 (Feb. 7, 2018) (“The element of

reasonableness requires that the detention be

18

imposed in pursuance of a legitimate aim in each

individual case.”).

Detention “as part of a policy to deter future

asylum seekers, or to dissuade those who have

commenced their claims from pursuing them, is

contrary to the norms of refugee law.” Goodwin-Gill

at 54; see also UNHCR Detention Guidelines, ¶ 32;

Michael Kagan, Limiting Deterrence: Judicial

Resistance to Detention of Asylum-Seekers in Israel

and the United States, 51 Texas Int’l L. J. 191, 195

(2016) (detention for the purpose of general deterrence

“focus[es] on deterring people who are not even parties

to the proceedings”). The Working Group on Arbitrary

Detention has further observed that the “degrading

conditions” to which many detained immigrants are

subjected in the United States are an unlawful

“deterrent to legitimate asylum claims.”

2017

Working Group Report, ¶ 87. Mandatory detention,

which often functions solely as a punitive deterrent to

legitimate claims for refugee protection, is thus

contrary to international law.

B.

International Law Imposes Special

Restrictions on the Detention of

Migrant Children

The Government’s unsupportable interpretation of

the INA further ignores the special protections

afforded to children under binding international

treaties. These safeguards prohibit the detention of

children for reasons related to their immigration

status in almost all cases. In those rare circumstances

where detention of a child for immigration purposes

19

may be necessary, it should be used only as a last

resort and for the shortest possible measure of time.

Article 24 of the ICCPR mandates that every child

has “the right to such measures of protection as are

required by [his or her] status as a minor.” See also

Juvenile Reeducation Institute v. Paraguay,

Preliminary Objections, Merits, Reparations, and

Costs, Judgment, Inter-Am. Ct. H.R. (ser. C) No. 112,

¶¶ 147, 225-28 (Sept. 2, 2004) (explaining that “it is

the child’s vulnerability that necessitates special

measures of protection”); see also Roper v. Simmons,

543 U.S. 551, 553 (2005) (recognizing children’s

special vulnerability due to their age).

These protections are rooted in the principle that,

“[i]n all actions concerning children, whether

undertaken by public or private social welfare

institutions, courts of law, administrative authorities

or legislative bodies, the best interests of the child

shall be a primary consideration.” United Nations

Convention on the Rights of the Child (“CRC”) art. 3,

Nov. 20, 1989, 1577 U.N.T.S. 3 (emphasis added).7

International bodies and courts have consistently

recognized that immigration-based detention is never

in a child’s best interest. See, e.g., Rights and

Guarantees of Children in the Context of Migration

and/or in Need of International Protection, ¶ 154,

measure that responds to the child’s best interest”);

Rapporteur’s 2009 Report, ¶ 62; United Nations

Comm. on the Rights of the Child, Rep. of the 2012

in the Context of International Migration, ¶ 78 (“The

detention of a child because of their or their parent’s

migration status constitutes a child rights violation

and always contravenes the principle of the best

interests of the child.”).

For these reasons, international bodies have

concluded that the immigration-based detention of

children is generally prohibited under international

law. See, e.g., U.N. Comm. on the Protection of the

Rights of All Migrant Workers and Members of Their

Families, Joint General Comment No. 4 (2017), U.N.

Regarding the Detention of Refugee and Migrant

Children in the Migration Context (Jan. 2017)

9344/unhcr-stresses-urgent-need-states-endunlawful-detention-refugees-asylum.html (“Children

should never be held in immigration detention.”).

21

Due to the exceptional vulnerability of child

detainees, the detention of children can even amount

to torture, thereby violating the Torture Convention,

to which the United States is a party. See, e.g., Juan

Méndez (Special Rapporteur on Torture and Other

Cruel, Inhuman or Degrading Treatment or

Punishment), Rep. to the Human Rights Council,

¶ 80, U.N. Doc. A/HRC/28/68 (Mar. 5, 2015) (“[T]he

deprivation of liberty of children based on their or

their parents’ migration status is never in the best

interests of the child, exceeds the requirement of

necessity, becomes grossly disproportionate and may

constitute cruel, inhuman or degrading treatment of

migrant children.”); U.N. Gen. Assembly, Report of

the Independent Expert Leading the United Nations

Global Study on Children Deprived of Liberty, ¶ 6,

U.N. Doc. A/74/136 (July 11, 2019) (“[T]he available

evidence shows that immigration detention is harmful

to a child’s physical and mental health and exposes

the child to the risk of sexual abuse and

exploitation.”); Julie M. Linton et al., “Detention of

Immigrant Children,” 139 Pediatrics 4, 6 (Mar. 13,

2017) (“[E]ven brief detention can cause psychological

trauma and induce long-term mental health risks for

children”).8

Additionally, mandatory detention of asylum seekers with

reinstated removal orders may result in family separation,

where, for instance, a parent is subjected to mandatory detention

because of a prior removal order, but the child is entitled to a

custody hearing. Family separation is also prohibited under

international law. See ICCPR Article 17; Convention on the

Rights of the Child Articles 7 and 9; American Convention on

Human Rights Article 11. Family separation also violates the

Torture Convention and the ICCPR because it amounts to

8

22

In those rare circumstances where brief detention

of a child may be necessary, the detention must be

carried out “only as a measure of last resort and for

the shortest appropriate period of time.” UNHCR

Detention Guidelines, ¶ 51. Some experts, however,

have concluded that detention of children for

migration purposes cannot be justified as a measure

of last resort given the availability of non-custodial

alternatives. Manfred Nowak, The United Nations

Global Study on Children Deprived of Liberty 448-51

(2019). The Working Group on Arbitrary Detention—

after observing children in the United States, “some

only a few days old,” in detention “despite the

availability of less restrictive measures”—has

likewise noted that children should never be detained

“except as a measure of last resort and for the shortest

appropriate period of time, taking into account their

best interests as a primary consideration.” 2017

Working Group Report, ¶¶ 42, 44.

The Government’s interpretation of the INA would

deprive a child subject to reinstatement of removal

with his or her parent(s) of the individualized hearing

necessary to make certain that the child’s best

interests, in light of his or her unique circumstances,

are taken into account. At a minimum, a case-by-case

inquiry is essential to ensure that the child is detained

only as a last resort and for the shortest possible

period of time. The Government’s interpretation

would make this assessment impossible and, as such,

torture. See Physicians for Human Rights, You Will Never See

Your Child Again: The Persistent Psychological Effects of

Family Separation 5 (Feb. 2020), https://phr.org/wpcontent/uploads/2020/02/PHR-Report-2020-Family-SeparationFull-Report.pdf.

it cannot be squared with the United States’

obligations under international law.

III.

The United States Has an Obligation Under

International Law to Provide Prompt and

Periodic Court Review of All Detentions

The United States’ international treaty obligations

further require the Government to provide all those

who seek refugee protection with prompt and periodic

court review of their detention. ICCPR Article 9(4)

Anyone who is deprived of his liberty by

arrest or detention shall be entitled to

The right of detainees to prompt court review of

their detention is binding on the United States

through the ICCPR. See also U.N. Working Grp. on

Arbitrary Det., Rep. of the Working Group on

Arbitrary

Detention,

¶ 19,

U.N.

Doc.

WGAD/CRP.1/2015 (May 4, 2015) [hereinafter May

2015 Arbitrary Detention Report]; id. ¶ 19 n.35 (“The

right to bring such proceedings before a court is well

enshrined in treaty law[.]”). This is a “self-standing

human right, the absence of which constitutes a

human rights violation.” Id. ¶ 2.

The review proceedings guaranteed by the ICCPR

must also be conducted by a court that is independent

of the detaining authority. See id. ¶ 69 (the reviewing

court “must be a different body from the one that

ordered the detention”); UNHCR Detention

Guidelines, ¶ 47(iii) (“[T]he reviewing body must be

independent of the initial detention authority, and

possess the power to order release or to vary any

conditions of release.”).

The U.N. Human Rights

Committee has explained that the ICCPR “envisages

that the legality of detention will be determined by a

court so as to ensure a higher degree of objectivity and

independence in such control.” Torres v. Finland,

for the Protection of All Persons Under Any Form of

Detention or Imprisonment (Dec. 9, 1988).

25

Moreover, the reviewing court must have the

authority to order release. See A v. Australia, ¶ 9.5

(stating that court review under ICCPR art. 9(4)

“must include the possibility of ordering release”);

May 2015 Arbitrary Detention Report, ¶ 27.

Court review of detention must also be provided

periodically or regularly. See HRC General Comment

No. 35, ¶ 18 (detention “must be subject to periodic reevaluation and judicial review”). Periodic review is

necessary to prevent arbitrary detention because

“detention should not continue beyond the period for

which the State can provide appropriate justification.”

A v. Australia, ¶ 9.4; accord HRC General Comment

No. 35, ¶ 12 (“[D]etention is arbitrary if it is not

subject to periodic re-evaluation of the justification for

continuing the detention.”); Rapporteur’s 2012

Report, ¶ 21; May 2015 Arbitrary Detention Report,

¶ 61 (non-nationals should have access to “regular

periodic reviews of their detention to ensure it

remains necessary, proportional, lawful and nonarbitrary”); id. ¶ 82; id. ¶ 104(b) (court is empowered

to “consider whether the detention remains justified,

or whether release is warranted in light of all the

changing circumstances of the detained individual’s

case”).

The system the Government advocates—in which

those who seek refugee protection would be subject to

mandatory detention on the decision of U.S. Customs

and Border Protection or Immigration and Customs

Enforcement (“ICE”) to reinstate a removal order

depriving them of an immigration court custody

hearing—is at odds with these requirements. Even if

ICE did fairly exercise its discretion to release some

asylum seekers, the United States’ international law

26

obligations require that review of detention be

conducted by a different body from the one that orders

detention.

Accordingly, the Government must

“ensure that the decision to detain a non-citizen is

promptly assessed by an independent court” and

guarantee that “immigration detainees are given the

chance to have their custody reviewed in a hearing

before an immigration judge.” Jorge Bustamante

(Special Rapporteur on the Human Rights of

Migrants), Rep. to the Human Rights Council ¶¶ 122,

123, U.N. Doc. A/HRC/7/12/Add.2 (Mar. 5, 2008). The

Inter-American Commission on Human Rights

recommends that U.S. detention determinations be

conducted on a case-by-case basis, subject to judicial

review, and that immigrants be permitted to appeal

detention decisions to an immigration court. InterAm. Comm’n H.R., Rep. on Immigration in the United

States: Detention and Due Process, ¶¶ 429, 431,

OEA/Ser.L/V/II Doc. 78/10 (Dec. 30, 2010). The U.N.

Working Group on Arbitrary Detention has similarly

stated that “[i]ndividualised review should comply

with procedural requirements of international law,

including: the requirement that the State bear the

burden of proof to demonstrate that it has a legitimate

interest in detention, the provision of automatic and

periodic bond hearings, and the requirement that

immigration judges consider the accrued length of

detention in deciding whether to release an

individual.” U.N. Working Grp. on Arbitrary Det.,

The Government argues that “aliens detained

under Section 1231(a) retain substantial protection

from unwarranted detention.” Pet’rs Br. 34-36. But

in reality, the Government has, as a general matter,

chosen not to exercise discretion to release those

seeking refugee protection from detention. A 2015

analysis of data obtained through the Freedom of

Information Act revealed that “in over 85% of

withholding-only cases, respondents remained

detained throughout the adjudication of their claims.”

Lindsay M. Harris, Withholding Protection, 50.3

Columbia Human Rights L. Rev., 12 n.27 (2019)

(citing David Hausman, Am. Civil Liberties Union

Found., Fact Sheet: Withholding-Only Cases and

Detention 2 (2015)). In addition, various reports

indicate that ICE’s detention decisions have in many

cases been inconsistent, arbitrary, and/or not actually

based on assessments of the particular individual’s

circumstances: for example, ICE parole decisions for

“arriving asylum seekers” often fail to actually involve

assessments of the necessity of detention in each

particular individual’s case; ICE officers often fail to

parole asylum seekers who meet the criteria detailed

in ICE’s own parole directive applicable to “arriving

asylum seekers”; and these problems have worsened

in recent years. See, e.g., Damus v. Nielsen, 313 F.

Supp. 3d 317, 339-42 (D.D.C. 2018) (finding that

“individualized parole determinations are likely no

longer par for the course” based in part on an observed

“drastic decline in parole-grant rates”); Mons v.

IV.

Arbitrary Detention Impedes Access to

Refugee Protection and Can Lead to

Refoulement

Under binding international treaties, the United

States must not return those seeking refugee

protection to countries where they face persecution or

torture. This prohibition, known as the principle of

non-refoulement, is codified in treaties to which the

United States is bound as a party. See, e.g., Refugee

10 As these reports indicate, in many cases parole decisions

are not actually based on an individualized assessment, but

instead on factors such as the availability of bed space in

detention facilities, local ICE detention policies, and/or a desire

to deter other asylum seekers from seeking refugee protection in

the United States. See California Report at 5-6; HRF Report at

2-3, 14-17, 22-24, 30-31; see also U.S. Comm’n on Int’l Religious

Freedom, Barriers to Protection 47-48 (2016) (parole bond rates

reported based on availability of detention beds).

29

Convention art. 33.1 (incorporated by the Refugee

Protocol, to which the United States is a party) (“No

Contracting State shall expel or return [] a refugee in

any manner whatsoever to the frontiers of territories

where his life or freedom would be threatened on

account of his race, religion, nationality, membership

of a particular social group or political opinion.”);

Torture Convention art. 3 (“No State Party shall

expel, return [] or extradite a person to another State

where there are substantial grounds for believing that

he would be in danger of being subjected to torture.”).

Arbitrary detention of people seeking refugee

protection frustrates the Government’s ability to

comply with this principle and, in many cases, leads

to “refoulement in disguise.” Nils Melzer (Special

Rapporteur on Torture and Other Cruel, Inhuman or

Degrading Treatment or Punishment), Rep. to the

Human Rights Council, ¶ 45, U.N. Doc. A/HRC/37/50

(Feb. 26, 2018). Even where legal safeguards are

available in theory to prevent unlawful detention,

many detained non-citizens simply do not have a

means “to access [] such substantive, procedural, and

institutional guarantees.” U.N. Working Grp. on

Arbitrary Det., Rep. of the Working Group on

Arbitrary Detention, ¶¶ 42, 43, U.N. Doc.

A/HRC/10/21 (Feb. 16, 2009).

Detention impedes access to legal assistance,

which is among the most important factors in

determining the outcome of an immigrant’s case.

“Having a lawyer is associated with better outcomes

at every stage in the immigration court process,” and

it “is particularly vital to ensuring a fair court process

for parents and children who have endured violence in

their countries and during their journeys.” Eagly et.

30

al., 106 Cal. L. Rev. at 815-16. In one recent study of

U.S. immigrants who challenged their removal, “49%

of released family members with counsel were

successful, as were 37% of represented detained

family members. In comparison, for those without

counsel, only 7% of released family members and 8%

of detained family members had success” in avoiding

removal.” Id. at 846. Unrepresented detainees are

not only less likely to succeed in court but are also far

less likely to apply for relief in the first place. Another

recent study found that “[d]etained immigrants with

counsel were nearly 11 times more likely to seek relief

such as asylum than those without representation (32

percent with counsel versus 3 percent without).”

American Immigration Council, “Access to Counsel in

Immigration

Court”

(Sept.

2016),

https://www.americanimmigrationcouncil.org/sites/de

fault/files/research/access_to_counsel_in_immigratio

n_court.pdf.

Despite the critical impact of representation on the

likelihood of success in immigration proceedings,

detained immigrants are “the least likely [of all

immigrants] to obtain representation.” Id. The same

study, for example, found that “[o]nly 14 percent of

detained immigrants acquired legal counsel,

compared

with

two-thirds

of

non-detained

immigrants.” Id.; see also Eagly et. al., 106 Cal. L.

Rev. at 790–91.

Non-citizens without legal

representation are thus at much greater risk of

refoulement.

In addition to hindering access to representation,

immigration-based

detention

“increases

the

vulnerability of” immigrants, causing many to “face

increased risks to their health and wellbeing and to

31

their psychological or mental state.” U.N. High

Comm’r for Refugees, UNHCR Emergency Handbook,

“Detention (and freedom of movement) of persons of

concern,”

https://emergency.unhcr.org/entry/44484/detentionand-freedom-of-movement-of-persons-of-concern.

Numerous medical associations have recognized the

severe physical and psychological toll that detention

takes on immigrant populations.11

Some non-citizens give up on their claims for

refugee protection and return to the countries from

which they fled, rather than subject themselves to

continued physical and psychological suffering in

detention. See, e.g., 2017 Working Group Report, ¶ 87

(“[T]he current system of detaining immigrants and

asylum seekers is, in many cases . . . a deterrent to

legitimate asylum claims.”); Riddhi Mukhopadhyay,

Death in Detention: Medical and Mental Health

in United States, 7 Seattle J. for Social Justice 693,

https://www.acponline.org/acp_policy/policies/family_detention_

position_statement_2018.pdf (finding detention of children and

families “can be expected to result in considerable adverse harm

. . ., including physical and mental health, that may follow them

standards in these detention centers . . . detainees’ mental health

is negatively impacted by disempowerment and lack of control.”).

32

their claims for release . . . despite the fear of

persecution or no knowledge of the place to which they

are being deported.”); Eagly et. al., 106 Cal. L. Rev. at

714–15 (“[A]fter being separated from their young

children during mandatory detention, many parents

have abandoned their asylum claim and returned to

countries they had escaped, despite fearing for their

own safety.”).

A recent story offers a vivid example of the

impediments that detainees encounter in pursuing

legitimate claims for refugee protection. A teacher

from Somalia, Yuusuf (a pseudonym used to ensure

his safety), fled to the United States after extremist

groups murdered his daughter, sister, and fellow

teachers. Southern Poverty Law Center Report,

“Detention system forces people to give up claims to

stay

in

U.S.”

(Oct.

4,

2018),

https://www.splcenter.org/news/2018/10/04/splcreport-detention-system-forces-people-give-claimsstay-us. Yuusuf sought asylum upon entry and

endured “more than two years in inhumane

conditions” in immigration detention, on top of “a

long, grueling legal process.” Id. Having lost his

ability to cope with the conditions of his confinement,

Yuusuf ultimately stopped fighting his unlawful

detention and was deported. Reflecting on the time

he spent seeking refuge in the United States, Yuusuf

observed: “This is more than jail . . . . In jail, you get

your sentence and you know when you are free, but

detention is endless.” Id.

Combined, the institutional constraints, physical

confinement and emotional trauma caused by

immigration-based detention greatly reduce the

likelihood that non-citizens will successfully obtain

33

refugee protection in the United States—regardless of

whether they have a legitimate fear of persecution if

returned to their home countries. The Government’s

interpretation of the INA, which would result in

arbitrary and indefinite detention of those who seek

refuge in this country, therefore violates the United

States’ obligation to respect the principle of nonrefoulement.

CONCLUSION

For the reasons set forth above, this Court should

affirm the Court of Appeals’ decision in this case.
