Detention of U.S. Persons as Enemy Belligerents

Summary

The detainee provisions passed as part of the National Defense Authorization Act for FY2012,

P.L. 112-81, affirm that the Authorization for Use of Military Force (AUMF), P.L. 107-40, in

response to the terrorist attacks of September 11, 2001, authorizes the detention of persons

captured in connection with hostilities. The act provides for the first time a statutory definition of

covered persons whose detention is authorized pursuant to the AUMF. During debate of the

provision, significant attention focused on the applicability of this detention authority to U.S.

citizens and other persons within the United States. The Senate adopted an amendment to clarify

that the provision was not intended to affect any existing law or authorities relating to the

detention of U.S. citizens or lawful resident aliens, or any other persons captured or arrested in

the United States. This report analyzes the existing law and authority to detain U.S. persons,

including American citizens and resident aliens, as well as other persons within the United States

who are suspected of being members, agents, or associates of Al Qaeda or possibly other terrorist

organizations as “enemy combatants.”

The Supreme Court in 2004 affirmed the President’s power to detain “enemy combatants,”

including those who are U.S. citizens, as part of the necessary force authorized by Congress after

the terrorist attacks of September 11, 2001. In Hamdi v. Rumsfeld, a plurality held that a U.S.

citizen allegedly captured during combat in Afghanistan and incarcerated at a Navy brig in South

Carolina is entitled to notice and an opportunity to be heard by a neutral decision maker regarding

the government’s reasons for detaining him. On the same day, the Court in Rumsfeld v. Padilla

overturned a lower court’s grant of habeas corpus to another U.S. citizen in military custody in

South Carolina on jurisdictional grounds, leaving undecided whether the authority to detain also

applies to U.S. citizens arrested in the United States by civilian authorities. Lower courts that

have addressed the issue of wartime detention within the United States have reached conflicting

conclusions. While the U.S. Court of Appeals for the Fourth Circuit ultimately confirmed the

detention authority in principle in two separate cases (one of which was subsequently vacated),

the government avoided taking the argument to the Supreme Court by indicting the accused

detainees for federal crimes, making their habeas appeals moot and leaving the law generally

unsettled. A federal judge enjoined the detention of persons on the basis of providing support to

or associating with belligerent parties under one prong of the definition enacted as Section 1021

of the National Defense Authorization Act for FY2012, P.L. 112-81 (Hedges v. Obama), but the

decision has been reversed on appeal on the basis of standing.

This report provides a background to the legal issues presented, followed by a brief introduction

to the law of war pertinent to the detention of different categories of individuals. An overview of

U.S. practice during wartime to detain persons deemed dangerous to the national security is

presented. The report concludes by discussing Congress’s role in prescribing rules for wartime

detention, subsequent legislation in the 112th Congress that addresses the detention of U.S.

persons, and legislative proposals in the 113th Congress to further address the issue (H.R. 1960, S.

1147, H.R. 2325, and H.R. 3304.

Detention of U.S. Persons as Enemy Belligerents

T

he detainee provisions passed as part of the National Defense Authorization Act for

FY2012 (2012 NDAA; P.L. 112-81), affirm that the Authorization for Use of Military

Force (AUMF)1 in response to the terrorist attacks of September 11, 2001, authorize the

detention of persons captured in connection with hostilities. The act provides for the first time a

statutory definition of covered persons whose detention is authorized pursuant to the AUMF.2

During consideration of the detention provision, much of the debate focused on the applicability

of this detention authority to U.S. citizens and other persons within the United States.3 Congress

ultimately adopted a Senate amendment to clarify that the provision is not intended to affect any

existing law or authorities relating to the detention of U.S. citizens or lawful resident aliens, or

any other persons captured or arrested in the United States.4 This report analyzes the existing law

and authority to detain, as “enemy combatants,”5 U.S. persons, which, for the purpose of this

1

Authorization for Use of Military Force (“the AUMF”), P.L. 107-40, 115 Stat. 224 (2001).

The National Defense Authorization Act for FY2012 (“FY2012 NDAA”) defines “covered persons” in Section

1021(b):

(1) A person who planned, authorized, committed, or aided the terrorist attacks that occurred on

September 11, 2001, or harbored those responsible for those attacks.

(2) A person who was a part of or substantially supported al-Qaeda, the Taliban, or associated

forces that are engaged in hostilities against the United States or its coalition partners, including

any person who has committed a belligerent act or has directly supported such hostilities in aid of

such enemy forces.

National Defense Authorization Act for FY2012 and Beyond: Detainee Matters, by (name redacted) and (name redacte

d).

S.Amdt. 1456. The amendment added a new paragraph (e) to Section 1021 with the subhead “Authorities”:

Nothing in this section shall be construed to affect existing law or authority relating to the detention

of United States citizens, lawful resident aliens of the United States, or any other persons who are

captured or arrested in the United States.

The language was amended slightly in conference by replacing “or” between “citizens” and “lawful resident aliens”

with a comma and adding a comma before “or any other persons.” It is unclear whether the language “captured or

arrested in the United States” is meant to apply to all three groups or whether the place of arrest is important only with

respect to “other persons.” It seems more likely that the latter meaning was intended, given that there would have been

no need to mention citizens or residents at all if all persons captured within the United States (but none captured

abroad) were sufficient to describe the intended class.

5

The term “enemy combatants” was used by the Bush Administration to define persons subject to detention under the

law of war and by the Supreme Court to describe persons subject to detention under the AUMF. Under the law of war,

enemy combatants are generally members of the military of the opposing party who are authorized to participate

directly in battle (as opposed to noncombatants, such as military surgeons and medics). Enemy combatants may be

targeted by the military or captured and detained as a wartime preventive measure. See generally CRS Report

RL31367, Treatment of “Battlefield Detainees” in the War on Terrorism. In 2004, the Department of Defense

established Combatant Status Review Tribunals at the Guantanamo Bay Naval Station to permit detainees to contest

their detention, defining the term “enemy combatant” to mean:

an individual who was part of or supporting Taliban or al Qaeda forces, or associated forces that are

engaged in hostilities against the United States or its coalition partners. This includes any person

who has committed a belligerent act or has directly supported hostilities in aid of enemy armed

forces.

Department of Defense Order of July 9, 2004, available at http://www.defenselink.mil/news/Jul2004/

d20040707review.pdf . The D.C. Circuit has endorsed this definition in subsequent cases. The Obama Administration

has retired the term “enemy combatant,” referring instead simply to persons who may be detained pursuant the AUMF,

defined with reference to the law of war as follows:

The President has the authority to detain persons that the President determines planned, authorized,

committed, or aided the terrorist attacks that occurred on September 11, 2001, and persons who

harbored those responsible for those attacks. The President also has the authority to detain persons

who were part of, or substantially supported, Taliban or al-Qaida forces or associated forces that

Detention of U.S. Persons as Enemy Belligerents

report means persons who are generally understood to be subject to U.S. territorial jurisdiction or

otherwise entitled to constitutional protections; that is, American citizens, resident aliens, and

other persons within the United States.

Background

In June, 2004, the Supreme Court handed down a series of opinions related to wartime detention

authority.6 In Hamdi v. Rumsfeld,7 a plurality of the Court held that a U.S. citizen allegedly

captured during combat in Afghanistan and incarcerated at a Navy brig in South Carolina could

be held as an enemy combatant as part of the necessary force authorized by Congress after the

terrorist attacks of September 11, 2001, but that he was entitled to notice and an opportunity to be

heard by a neutral decision maker regarding the government’s reasons for detaining him. The

government instead reached an agreement with the petitioner that allowed him to return to Saudi

Arabia, where he also holds citizenship, subject to certain conditions. On the same day, the Court

in Rumsfeld v. Padilla8 overturned a lower court’s grant of habeas corpus to another U.S. citizen

in military custody in South Carolina on jurisdictional grounds, sending the case to a district court

in the Fourth Circuit for a new trial. The vacated decision of the U.S. Court of Appeals for the

Second Circuit had held that the circumstance of a U.S. citizen arrested in the United States on

suspicion of planning to carry out a terrorist attack there was fundamentally different from the

case of a citizen captured on the battlefield overseas,9 and that the detention of such a citizen

without trial was therefore precluded by the Non-Detention Act, 18 U.S.C. Section 4001(a),10

which provides that no U.S. citizen may be detained except pursuant to an act of Congress. A

plurality of the Court found in Hamdi that the President’s detention of a U.S. citizen captured on

the battlefield is not foreclosed by the Non-Detention Act because an act of Congress, the AUMF,

explicitly authorized such detention, but emphasized the narrow limits of the authority it was

approving:11

(...continued)

are engaged in hostilities against the United States or its coalition partners, including any person

who has committed a belligerent act, or has directly supported hostilities, in aid of such enemy

armed forces.

In addition to the Hamdi and Padilla cases discussed more fully below, the Court decided in Rasul v. Bush, 542 U.S.

466 (2004), that aliens detained as “enemy combatants” at the detention facility at the Guantanamo Bay Naval Station

had the right to challenge their detention under the habeas corpus statute, 28 U.S.C. §2241. The government had argued

that U.S. courts lacked jurisdiction to hear habeas petitions filed on behalf of aliens detained abroad. For a description

of these cases, see CRS Report RS21884, The Supreme Court 2003 Term: Summary and Analysis of Opinions Related

Detention of U.S. Persons as Enemy Belligerents

The AUMF authorizes the President to use “all necessary and appropriate force” against

“nations, organizations, or persons” associated with the September 11, 2001, terrorist attacks.

115 Stat. 224. There can be no doubt that individuals who fought against the United States in

Afghanistan as part of the Taliban, an organization known to have supported the al Qaeda

terrorist network responsible for those attacks, are individuals Congress sought to target in

passing the AUMF. We conclude that detention of individuals falling into the limited

category we are considering, for the duration of the particular conflict in which they were

captured, is so fundamental and accepted an incident to war as to be an exercise of the

“necessary and appropriate force” Congress has authorized the President to use.12

The plurality went on to describe the kind of detention it had in mind was the traditional practice

of detaining prisoners of war13 under long-standing law of war principles:

Further, we understand Congress’ grant of authority for the use of “necessary and

appropriate force” to include the authority to detain for the duration of the relevant conflict,

and our understanding is based on longstanding law-of-war principles. If the practical

circumstances of a given conflict are entirely unlike those of the conflicts that informed the

development of the law of war, that understanding may unravel. But that is not the situation

we face as of this date. Active combat operations against Taliban fighters apparently are

ongoing in Afghanistan. The United States may detain, for the duration of these hostilities,

individuals legitimately determined to be Taliban combatants who “engaged in an armed

conflict against the United States.” If the record establishes that United States troops are still

involved in active combat in Afghanistan, those detentions are part of the exercise of

“necessary and appropriate force,” and therefore are authorized by the AUMF.14

Justice Souter, joined by Justice Ginsburg joined the plurality opinion to provide sufficient votes

to vacate the decision below and remand the case to give Hamdi an opportunity to contest his

detention. However, finding no explicit authority in the AUMF (or other statutes) to detain

persons as enemy combatants, they would have determined that 18 U.S.C. Section 4001(a)

precludes the detention of American citizens as enemy combatants altogether. They rejected the

theory that the detention was authorized as a necessary incident to the use of military force

because “the Government’s stated legal position in its campaign against the Taliban ... is

apparently at odds with its claim here to be acting in accordance with customary law of war and

hence to be within the terms of the Force Resolution in its detention of Hamdi.”15 In other words,

the two Justices appeared to agree in principle that the AUMF could authorize the detention of

prisoners of war, but took the view that the government’s failure to accord the Taliban detainees

rights under the Geneva Convention vitiated that authority.

Justice Scalia, joined by Justice Stevens, dissented, arguing that “our constitutional tradition has

been to prosecute [U.S. citizens accused of waging war against the government] in federal court

Id. at 518 (citing various authorities related to prisoner of war custody); id. at 522 (distinguishing ex parte Milligan,

4 Wall. (71 U.S.) 2 (1866), in which “the Court made repeated reference to the fact that its inquiry into whether the

military tribunal had jurisdiction to try and punish Milligan turned in large part on the fact that Milligan was not a

prisoner of war, but a resident of Indiana arrested while at home there. ...That fact was central to its conclusion.”).

Id. at 521. “Under the definition of enemy combatant that we accept today as falling within the scope of Congress’

of the relevant conflict.” Id. at 526.

Detention of U.S. Persons as Enemy Belligerents

for treason or some other crime”16 unless Congress has suspended the Writ of Habeas Corpus

pursuant to the Constitution’s Suspension Clause, Art. I, Section 9, cl. 2. They viewed as

“unthinkable that the Executive could render otherwise criminal grounds for detention

noncriminal merely by disclaiming an intent to prosecute, or by asserting that it was

incapacitating dangerous offenders rather than punishing wrongdoing.” Under their view, even if

the AUMF did authorize detention in sufficiently clear language to overcome the prohibition in

18 U.S.C. Section 4001(a) (which, in their view, clearly it did not), Hamdi’s detention would have

been unconstitutional without a proper suspension of the Writ. Justice Scalia described his

position as pertaining only to U.S. citizens detained within the United States (regardless of where

captured),17 suggesting that only citizens who were concededly members of enemy forces may be

detained as prisoners of war within the United States.18

Justice Thomas also dissented, essentially agreeing with the government’s position that the

detention of enemy combatants is an unreviewable aspect of the war powers constitutionally

allocated to the political branches.19 He agreed that the AUMF provides sufficient authority to

detain enemy combatants, meaning that a majority of the Court approved that position, but he

would have given utmost deference to the Executive branch and accorded little in the way of due

process. Finally, he questioned whether other acts of war, such as bombings and missile strikes,

would also be subject to due process inquiry.20

Although a bare majority of the Court, led by Chief Justice Rehnquist, declined to decide in

Padilla whether the detention authority approved in Hamdi would apply to a U.S. citizen arrested

in the United States, four Justices who dissented on the question of jurisdiction also indicated

they would have upheld the Second Circuit’s grant of the petition on the merits.21 Apparently

rejecting the Bush Administration’s contention that it had the authority to detain a U.S. citizen

who was alleged to be “closely associated with Al Qaeda” and to have “engaged in ... hostile and

war-like acts, including ... preparation for acts of international terrorism” against the United

States22 in order to extract intelligence and prevent him from aiding Al Qaeda,23 Justice Stevens,

joined by Justices Souter, Ginsburg, and Breyer, wrote:

Executive detention of subversive citizens, like detention of enemy soldiers to keep them off

the battlefield, may sometimes be justified to prevent persons from launching or becoming

missiles of destruction. It may not, however, be justified by the naked interest in using

unlawful procedures to extract information. Incommunicado detention for months on end is

States” and the risk he posed to U.S. national security, which was determined to make his military detention “necessary

Detention of U.S. Persons as Enemy Belligerents

such a procedure. Whether the information so procured is more or less reliable than that

acquired by more extreme forms of torture is of no consequence. For if this Nation is to

remain true to the ideals symbolized by its flag, it must not wield the tools of tyrants even to

resist an assault by the forces of tyranny.24

Given Justice Scalia’s dissent in Hamdi, it appeared in 2004 that a majority of the Supreme Court

as it was then constituted would have determined that the Non-Detention Act precludes the

detention of a U.S. citizen without trial based on an alleged association with Al Qaeda and

participation in a terrorist plot far from any conventional battlefield, at least within the United

States. A separate majority of the same Court took the view that the Non-Detention Act does not

preclude the detention of a U.S. citizen picked up on the battlefield in Afghanistan, albeit

apparently for different reasons.25 There also appears to have been a majority on the Court who

believed that indefinite detention solely for the purpose of interrogation would be impermissible

even where they agreed the law of war supports detention.26 Finally, a majority took the position

that a U.S. citizen detained under the authority of the AUMF would have the right to a

meaningful opportunity to be heard before a neutral decision maker in order to contest the factual

basis for the detention, although there was disagreement as to the precise level of due process

such a hearing would be constitutionally required to provide.27

A majority of the Hamdi Court appears to have accepted the view that, in principle, U.S. citizens

who join an enemy armed force and engage in hostilities against the United States may be treated

as enemy belligerents on the same basis that alien enemy belligerents may be so treated under the

laws and usages of war.28 It seems to follow that the same criteria and definition used to

determine the status of aliens who are believed to be enemy belligerents would apply equally to

U.S. citizens. Thus, there is little reason to suppose that the contours of the legal category of

24

Id. at 465 (Stevens, J., dissenting).

Justice O’Connor and the three others who joined the controlling plurality opinion did not decide whether the NonDetention Act was applicable at all to military detentions. Id. at 517. Justice Thomas, in dissent, did not expressly

address the application of the Non-Detention, but agreed that detention was permissible.

26

Padilla, 542 U.S. at 464 (Stevens, J. dissenting); Hamdi, 542 U.S. at 521(O’Connor, J., plurality opinion)

(“Certainly, we agree that indefinite detention for the purpose of interrogation is not authorized.”).

27

Justice O’Connor wrote in Hamdi that the exigencies of the circumstances may allow for a tailoring of enemy

combatant proceedings “to alleviate their uncommon potential to burden the Executive at a time of ongoing military

conflict,” possibly allowing hearsay evidence and “a presumption in favor of the Government’s evidence,” as long as a

fair opportunity to rebut such evidence is provided. Hamdi, 542 U.S. at 543. Justice Souter, joined by Justice Ginsburg,

agreed that Hamdi was entitled to due process, including the right to counsel, but did not agree with the suggestion that

“the Government could claim an evidentiary presumption casting the burden of rebuttal on Hamdi, or that an

opportunity to litigate before a military tribunal might obviate or truncate enquiry by a court on habeas....” Id. at 553-54

(Souter, J., concurring in part). Justices Scalia and Stevens would have found the full trappings of a criminal trial

necessary in the absence of a suspension of the Writ of Habeas Corpus, and in any event, did not believe the Court

should engage in legislating alternative procedures. Id. at 554, 576 (Scalia, J., dissenting). Justice Thomas alone would

have accepted the government’s view that it need only show “some evidence” in order to establish that detention is

warranted, arguing that the Federal Government’s war powers can not be “balanced away by this Court” and that only

Congress should be able to “provide for additional procedural protections....” Id. at 579 (Scalia, J., dissenting).

28

See id. at 519 (O’Connor, J. plurality opinion) (citing ex parte Quirin, 317 U.S. 1, 20 (1943) for proposition that

“[t]here is no bar to this Nation’s holding one of its own citizens as an enemy combatant.”); id. at 548-49 (Souter, J.,

concurring in part) (suggesting that ex parte Quirin may support the “proposition that the American citizenship of [a

wartime captive] does not as such limit the Government’s power to deal with him under the usages of war.”); id. at 587

(Thomas, J., dissenting) (stating that the war power “quite obviously includes the ability to detain those (even United

States citizens) who fight against our troops or those of our allies”) (citations omitted). Justices Scalia, on the other

hand, would have found ex parte Milligan controlling, suggesting that Quirin mischaracterized rather than

distinguished Milligan. Id. at 579 (Scalia, J., dissenting). The interplay between these two cases is discussed infra.

Detention of U.S. Persons as Enemy Belligerents

persons subject to detention, as it has been developed by the lower courts interpreting Hamdi,29

by the executive branch, and most recently, by Congress, will differ according to citizenship. It

may be the case that U.S. citizenship will entitle citizen-detainees to more procedural rights in

contesting the factual basis for their detention than alien detainees have enjoyed. Moreover, there

is no dispute that citizens detained in U.S. custody abroad may seek habeas review, and Congress

has not stripped the courts of jurisdiction over non-habeas cases by U.S. citizens detained as

enemy belligerents, as it has done with respect to aliens,30 nor has it established jurisdiction in

military commissions to try citizens for war crimes.31 On the other hand, lower courts have

applied the plurality opinion in Hamdi, which decision expressly deals with the rights of a U.S.

citizen-detainee, as a baseline for determining the procedural rights due to aliens detained at

Guantanamo in habeas proceedings, apparently without requiring proof of the existence of

“exigent circumstance.”32 Assuming that the Supreme Court jurisprudence establishes that

citizens accused of participating in hostilities against the United States may be treated the same as

similarly situated aliens, the seemingly relaxed procedural rights and evidentiary burden

applicable in the Guantanamo cases may also apply to any habeas cases involving citizendetainees.33

29

The Hamdi Court stressed the narrow nature of the category of persons whose detention it found authorized, but

suggested that courts might apply a broader definition:

Here the basis asserted for detention by the military is that Hamdi was carrying a weapon against

American troops on a foreign battlefield; that is, that he was an enemy combatant. The legal

category of enemy combatant has not been elaborated upon in great detail. The permissible bounds

of the category will be defined by the lower courts as subsequent cases are presented to them.

Hamdi, 542 U.S. at 522 n.1 (O’Connor, J., plurality opinion).

Section 7 of the Military Commission Act of 2006 (“MCA”), P.L. 109-366, 120 Stat. 2600, 2635 (codified at 28

U.S.C. §2241(e)), stripped courts of habeas jurisdiction over aliens detained as enemy combatants as well as any other

type of claim by such persons (except for two now defunct appellate provisions passed as part of the Detainee

Treatment Act, P.L. 109-148, div. A, title X, §1005, December 30, 2005, codified as amended at 10 U.S.C. §801 note).

28 U.S.C. §2241(e)(2) provides:

[N]o court, justice, or judge shall have jurisdiction to hear or consider any ... action against the

United States or its agents relating to any aspect of the detention, transfer, treatment, trial, or

conditions of confinement of an alien who is or was detained by the United States and has been

determined by the United States to have been properly detained as an enemy combatant or is

awaiting such determination.

While the Supreme Court in Boumediene v. Bush, 553 U.S. 723 (2008), struck Section 7 of the MCA as

unconstitutional insofar as it stripped courts of habeas jurisdiction over the same class of aliens (28 U.S.C.

§2241(e)(1)), the Court did not address the constitutionality of §2241(e)(2), and lower courts have continued to apply it

to dismiss various claims by alien detainees. See, e.g., Al-Janko v. Gates, Civil Case No. 10-1702 (RJL), slip op. at 14

& n.12 (D.D.C. 2011) (citing cases). While the Boumediene decision affirms that aliens held at Guantanamo have a

constitutional right to seek habeas relief, aliens held elsewhere abroad are not necessarily guaranteed that privilege.

Maqaleh v. Gates, 605 F.3d 84 (D.C. Cir. 2010).

31

10 U.S.C. §948C provides that “[a]ny alien unprivileged enemy belligerent is subject to trial by military commission

as set forth in [chapter 47a of title 10, U.S. Code].” 10 U.S.C. §948A(1) defines “alien” to mean “an individual who is

not a citizen of the United States.”

It also seems that the plurality was envisioning a process to be implemented by military officials in the field rather

than procedures to apply in federal court, yet the plurality opinion also mentioned the Justices’ view that the process

suggested by the government for district court purposes and that affirmed by the appellate court was too little, while the

process insisted upon by Judge Doumar at the district court level was too much. Hamdi, 542 U.S. at 532-33 (O’Connor,

Detention of U.S. Persons as Enemy Belligerents

The Supreme Court has not yet addressed on the merits whether an alien lawfully present in the

United States can be detained under the authority of the AUMF based on activity conducted there.

A noncitizen could not invoke the Non-Detention Act, but might nevertheless be able to contest

whether the government’s facts support an enemy combatant designation. After all, the Hamdi

plurality suggested there may be a distinction based on the fact that that case involved a capture

on a foreign battlefield.34 At about the same time that it issued Hamdi and Padilla, the Court

denied certiorari to review the case of Ali Saleh Kahlah al-Marri, a Qatari student who had been

arrested in Peoria, IL in late 2001 but declared an “enemy combatant” prior to trial and

transferred to military custody in South Carolina. His petition for habeas corpus was dismissed

for lack of jurisdiction by the U.S. Court of Appeals for the Seventh Circuit.35

Both al-Marri and Padilla filed new petitions for habeas corpus in the Fourth Circuit, meaning

that the issue of detention authority with respect to citizens and aliens within the United States

would have to be relitigated there before the Supreme Court would have another opportunity to

address it. As we explain more fully below, the Fourth Circuit ultimately confirmed both

detentions, but without establishing a conclusive test for determining which persons arrested

within the United States are subject to detention under AUMF authority. Supreme Court review

was avoided in both cases after the government filed charges against the petitioners and moved

them into the civilian court system. The only opinion left standing, that which affirmed the

detention of Jose Padilla on grounds very different from the original allegations that had been

addressed by the Second Circuit, does little to expand the understanding of detention authority

beyond that which Hamdi already established, that is, that detention is justified in the case of a

person who fought alongside enemy forces against the United States on a foreign battlefield.

Assuming, per Hamdi,36 that Congress intended in 2001 to authorize the use of force in

compliance with the law of war,37 and considering that Congress expressly incorporated the law

of war into the detention authority in the 2012 NDAA,38 a survey of international law regarding

such detentions may be pertinent to a determination of the detention authority preserved under the

2012 NDAA. Accordingly, this report summarizes wartime detention under international law and

surveys relevant U.S. practice before returning to the Fourth Circuit’s treatment of the Padilla and

There is some disagreement among judges on the U.S. Court of Appeals for the D.C. Circuit regarding whether the

AUMF should be interpreted in accordance with the law of war. In Al-Bihani v. Obama, 590 F.3d 866 (D.C. Cir. 2010),

Judge Brown denied that the law of war has any relevance to the courts’ interpretation of the scope of the detention

power conferred by the AUMF:

[W]hile the international laws of war are helpful to courts when identifying the general set of war

powers to which the AUMF speaks, their lack of controlling legal force and firm definition render

their use both inapposite and inadvisable when courts seek to determine the limits of the President’s

war powers.

opinion suggesting that this portion of the panel opinion was essentially nonbinding dicta, Al-Bihani v. Obama, 619

Status and Detention of Persons in War

The law of war divides persons in the midst of an armed conflict into two broad categories:

combatants and civilians.39 This fundamental distinction determines the international legal status

of persons participating in or affected by combat, and determines the legal protections afforded to

such persons as well as the legal consequences of their conduct.40 Combatants are those persons

who are authorized by international law to fight in accordance with the law of war on behalf of a

party to the conflict.41 Civilians are not authorized to fight, but are protected from deliberate

targeting by combatants as long as they do not take up arms. In order to protect civilians, the law

of war requires combatants to conduct military operations in a manner designed to minimize

civilian casualties and to limit the amount of damage and suffering to that which can be justified

by military necessity. To limit exposure of civilians to military attacks, combatants are required,

as a general rule, to distinguish themselves from civilians. Combatants who fail to distinguish

themselves from civilians run the risk of being denied the privilege to be treated as prisoners of

war if captured by the enemy.

The treatment of all persons who fall into the hands of the enemy during an international armed

conflict depends upon the status of the person as determined under the four Geneva Conventions

of 1949. Under these conventions, parties to an international armed conflict have the right to

capture and intern enemy soldiers42 as well as civilians who pose a danger to the security of the

state,43 at least for the duration of hostilities.44 The right to detain enemy combatants is not based

on the supposition that the prisoner is “guilty” as an enemy for any crimes against the Detaining

most frequently in the context of military rules of engagement, which stress that only enemy combatants may lawfully

be attacked during military operations.

See The Geneva Convention Relative to the Treatment of Prisoners of War, August 12, 1949, 6 U.S.T. 3317 (hereinafter

obligation of not leaving, beyond certain limits, the camp where they are interned, or if the said

camp is fenced in, of not going outside its perimeter. Subject to the provisions of the present

Convention relative to penal and disciplinary sanctions, prisoners of war may not be held in close

confinement except where necessary to safeguard their health and then only during the continuation

of the circumstances which make such confinement necessary.

Detention of U.S. Persons as Enemy Belligerents

Power, either as an individual or as an agent of the opposing state. POWs are detained for security

purposes, to remove those soldiers as a threat from the battlefield. The law of war encourages

capture and detention of enemy combatants as a more humane alternative to accomplish the same

purpose than by wounding or killing them.

Enemy civilians may be interned for similar reasons, when found on the territory belonging to or

occupied by a belligerent, although the law of war does not permit them to be treated as lawful

military targets. As citizens of an enemy country, they may be presumed to owe allegiance to the

enemy. The law of war traditionally allowed for their internment and the confiscation of their

property, not because they are suspected of having committed a crime or even of harboring ill will

toward the host or occupying power but, rather, they are held in order to prevent their acting on

behalf of the enemy and to deprive the enemy of resources it might use in its war efforts.

Congress has delegated to the President the authority, during a declared war or by proclamation,

to provide for the restriction, internment or removal of enemy aliens deemed dangerous.45 The

Supreme Court has upheld internment programs promulgated under the Alien Enemy Act.46 This

form of detention, like the detention of POWs, is administrative rather than punitive, and thus no

criminal trial is required.47 The Detaining Power may punish enemy soldiers and civilians for

crimes committed prior to their capture as well as during captivity, but only after a fair trial in

accordance with the relevant convention and other applicable international law.

The foregoing describes the law that applies in the case of international armed conflict, that is,

armed conflict between two states, as defined by the Geneva Conventions.48 Non-international

armed conflict is governed by Common Article 3 of the Geneva Conventions49 and Additional

45

50 U.S.C. §21 (defining “enemy” as “all natives, citizens, denizens, or subjects of the hostile nation or government,

being of the age of fourteen years and upward, who shall be within the United States and not actually naturalized”).

46

See Ludecke v. Watkins, 335 U.S. 160 (1948) (upholding President’s authority to order the removal of all alien

enemies “who shall be deemed by the Attorney General to be dangerous to the public peace and safety of the United

States”). The Supreme Court declined to review the determination by the Alien Enemy Hearing Board that the

petitioner was dangerous, and noted that no question as to the validity of the administrative hearings had been raised.

Id. at 163, n.4. However, the Court also noted that an enemy alien restrained pursuant to the act did have access to the

courts to challenge whether the statutory criteria were met, in other words, whether a “declared war” existed and

whether the person restrained is in fact an enemy alien fourteen years or older. Id. at 170-72, n.17.

Internees may challenge their detention in court by means of habeas corpus. See id.

The 1949 Geneva Conventions share several types of common provisions. The first three articles of each Convention

are identical. Common Article 3 has been described as “a convention within a convention” to provide a general formula

covering respect for intrinsic human values that would always be in force, without regard to the characterization the

parties to a conflict might give it. Article 3 provides, in part, that

1. Persons taking no active part in the hostilities, including members of armed forces who have laid

down their arms and those placed hors de combat by sickness, wounds, detention, or any other

cause, shall in all circumstances be treated humanely, without any adverse distinction founded on

race, colour, religion or faith, sex, birth or wealth, or any other similar criteria.

To this end, the following acts are and shall remain prohibited at any time and in any place

whatsoever with respect to the above-mentioned persons:

(a) Violence to life and person, in particular murder of all kinds, mutilation, cruel treatment

and torture;

(b) Taking of hostages;

(c) Outrages upon personal dignity, in particular humiliating and degrading treatment;

(d) The passing of sentences and the carrying out of executions without previous judgment

pronounced by a regularly constituted court, affording all the judicial guarantees which are

recognized as indispensable by civilized peoples.

Detention of U.S. Persons as Enemy Belligerents

Protocol II (“AP II”),50 or at least those parts of AP II that reflect customary international law (the

United States has not ratified AP II). Common Article 3 does not recognize a distinction between

combatant and civilian status, and neither expressly permits nor prohibits detention. Rather, it

provides minimal protections for those who fall into the hands of one of the parties to the armed

conflict. Some international legal scholars believe that detention is permitted in non-international

conflicts to at least the same extent that it is practiced in international armed conflicts,51 while

others argue that specific authority under domestic law is necessary to authorize and define the

scope of permissible detention during a non-international armed conflict.52 Another view might be

that the rules applicable to international armed conflict, as customary international law, apply to

non-international armed conflicts that meet the threshold for a belligerency under the

international law of war,53 while any sort of contention that does not rise to such a level falls

outside the law of war and is governed by domestic law only (in compliance with the state’s

obligations under international human rights law). In any event, the survey of U.S. practice

presented below appears to establish that statutory authority in addition to a declaration of war

has been seen as necessary to permit wartime detention within the United States, at least insofar

as the preventive detention of civilians or unprivileged belligerents are concerned.

U.S. Practice—Detention of Enemies on

U.S. Territory

The following sections give a brief treatment of the history of the internment of individuals who

are deemed “enemies” or determined to be too dangerous to remain at liberty during a war or

national emergency. A survey of the history reveals that persons who are considered likely to act

as an enemy agent on U.S. territory traditionally have been treated as alien enemies rather than

prisoners of war or “enemy combatants” by the military, even when the individuals were

members of the armed forces of enemy nations, although in the latter case they might also be tried

by military commission or court-martial, if accused of a crime. Persons acting within the territory

detention during a non-international armed conflict). Under this view, the failure of the relevant conventions to

authority to regulate the conduct of persons within their territory than an indication that fewer rules are meant to apply.

Detention of U.S. Persons as Enemy Belligerents

of the United States on behalf of an enemy government who were not part of its armed forces,

including American citizens accused of spying or sabotage, have been tried in federal court.

Individuals captured on the battlefield abroad have been handled in accordance with government

regulations interpreting the law of war.54

For the most part, it appears that U.S. practice has followed a traditional understanding of

international law, in which the formal relationship between states, or perhaps between a state and

a breakaway portion of its territory controlled by a government that no longer recognizes its

authority, plays a seemingly crucial role. During war, a person’s formal association with the

opposing government or armed forces was seen to have bearing on how the law applied. While

alien enemies and invading armies were seen to enjoy no (or at least very little) protection under

domestic law, those with merely personal sympathy toward the enemy or animosity toward the

government continued to enjoy such protection. For that reason, persons falling into the first

category could be interned as a wartime measure without any demonstration of personal hostility

on their part, while the validity of restrictive measures taken against other persons were assessed

in terms of necessity and adequacy of due process. At the same time, the first category of persons

enjoyed some protection under international law, including, for example, privileged belligerents

could not be tried as criminals for belligerent acts that did not violate the law of war.

The “Quasi War” with France and the War of 1812

During the summer of 1798, spurred by tensions involving the French Republic, Congress

enacted a series of national security measures known collectively as the Alien and Sedition Acts,55

which included the Alien Act56 and the Sedition Act,57 as well as the Alien Enemy Act.58 Of these

laws, only the Alien Enemy Act has survived into modern times.

The Alien Act empowered the President to order out of the country any noncitizen whom he

judged to be “dangerous to the peace and safety of the United States” or suspected to be

concerned in any “treasonable or secret machinations” against the government. Expelled aliens

convicted of having returned to the United States without obtaining a license to do so were

subject to imprisonment for such time as the President deemed necessary for the public safety.59

Outside of such a conviction, the act did not permit summary detention, but the law was

nonetheless controversial.

Part of the debate surrounding the Alien Act questioned the extent to which the Bill of Rights

covers “alien friends” on U.S. territory. Opponents argued that such aliens within the United

States are entitled to due process of law and the same protection from the government as citizens,

and that therefore, aliens suspected of being disposed to engage in Jacobin plots to overthrow the

social order or take part in other insurrectionist activities60 should be tried in court rather than

summarily deported.61 Proponents argued that aliens within the United States owe merely

temporary allegiance to the United States and are therefore not entitled to the same rights as

citizens, and that all governments have the right to deport aliens who pose a danger.62 The bill

passed along regional lines,63 but was never enforced, although some aliens left the country under

their own volition.64 Virginia and Kentucky passed resolutions declaring the Alien Act and the

Sedition Act to be unconstitutional,65 and it is widely believed that Thomas Jefferson’s opposition

to these Acts helped him win the presidency.66

The Alien Enemy Act was the last of the laws enacted to confront the crisis. It began:

Whenever there shall be a declared war between the United States and any foreign nation or

government, or any invasion or predatory incursion shall be perpetrated, attempted or

threatened against the territory of the United States by any foreign nation or government, and

the President of the United States shall make public proclamation of the event, all natives,

citizens, denizens, or subjects of the hostile nation or government, being males of the age of

fourteen years and upward, who shall be within the United States and not actually

naturalized, shall be liable to be apprehended, restrained, secured, and removed as alien

enemies.67

Unlike the Alien Act or the Sedition Act, the Alien Enemy Act was written to apply only during

declared wars or invasions by the armies of foreign governments. There was never a requirement

that an alien be suspected of engaging in any sort of hostile activities in order to be liable to

treatment under the act, although aliens “not chargeable with actual hostility ... or other crime

against the public safety” are afforded a grace period during which to arrange for “the recovery,

disposal, and removal of [their] goods and effects, and for [their] departure.” Also unlike its sister

Acts, the Alien Enemy Act engendered practically no controversy. Neither James Madison nor

Thomas Jefferson, who drafted the Virginia and Kentucky Resolutions, raised any objections;68

The bill did not address preventive detention except on conviction of returning without permission. Some opponents

ought to be withdrawn whenever they become ‘dangerous to the public safety’”).

Detention of U.S. Persons as Enemy Belligerents

and even the most vociferous opponents of the Alien Act in Congress were careful to clarify that

they had no qualms with respect to the Alien Enemy Act.69 The absence of objection to the Alien

Enemy Act by the same generation that drafted the Constitution has been held to provide

evidence both of the act’s constitutionality and the prevailing understanding of the legal principle

underlying it, that is, the fundamentally different position held by aliens on the basis of their

formal allegiance to a government with which the United States is at war.70

Of the enactments, only the Sedition Act addressed the activities of U.S. citizens in possible aid

of insurrection or foreign invaders. The act, which was also the only one of the three that was

ever enforced,71 was criticized as destructive of the newly established freedom of speech and of

the press, but it did not authorize detention without trial for citizens or aliens.

The first presidential proclamation under the Enemy Alien Act did not occur until the War of

1812, when President Madison ordered that alien enemies who resided within forty miles of tide

water must report to local marshals for assigned residency or other measures.72 Aliens subject to

the measures were entitled to seek habeas corpus relief to challenge the measures,73 and at least

one British subject prevailed,74 despite the familiar canon that enemy aliens have no access to the

courts.75 One American citizen who was detained militarily on suspicion of having aided the

British in preparation for their attack on Sackett’s Harbor was held to be entitled to habeas corpus

because there was no authority for the military to try such persons for treason.76 It does not appear

resident or sojourning noncitizens from friendly countries were considered to owe allegiance to the United States in

return for the protection of the Constitution and laws of the United States, citizens and invading soldiers from enemy

countries were not covered by this reciprocal arrangement because their allegiance was with an enemy government.

Even so, alien enemies were not categorically barred from asserting rights in court. See Clarke v. Morey, 10 Johns. 69

to have been asserted that U.S. citizens who aided the enemy could be detained without trial as

by the military without express statutory authority, even though the law of war permits it, based

on the fact that Congress had legislated with respect to enemy aliens and prisoners of war:

War gives an equal right over persons and property: and if its declaration is not considered as

prescribing a law respecting the person of an enemy found in our country, neither does it

prescribe a law for his property. The act concerning alien enemies, which confers on the

president very great discretionary powers respecting their persons, affords a strong

implication that he did not possess those powers by virtue of the declaration of war.78

The Civil War

The Civil War raised a host of novel issues regarding the application of the laws and usages of

war to enemies who were also U.S. citizens. Some who found themselves subject to wartime

measures argued that one could be either a citizen, entitled to all the constitutional protections

that applied in peacetime, or an enemy, entitled to no constitutional protections but under no

obligation to obey domestic laws; but not both.79 The courts rejected this contention, establishing

that the United States could, under the circumstances of de facto war, assert both belligerent

rights against the seceded states and sovereign rights to hold citizens of those states accountable

for treason and other crimes.80 Key to this determination was the fact that the civil war amounted

to a war within the meaning of international law (a “belligerency”) rather than a mere insurrection

to be dealt with using only the law enforcement capacity of the government.81 Once it was

established that the rebellion amounted to a belligerency, all citizens of seceded states were

technically public enemies and their property deemed hostile, even if they were not traitors in

thought or deed.82

department of the Government to which this power was entrusted. “He must determine what degree

of force the crisis demands.” The proclamation of blockade is itself official and conclusive

evidence to the Court that a state of war existed which demanded and authorized a recourse to such

a measure under the circumstances peculiar to the case.

At the same time, it appears that citizens of states that did not secede were not to be considered

public enemies unless they actually took up residence in the South or joined the Confederate

army, even if they favored the Confederacy or advocated dissolution of the Union. In the border

states where anti-Union sentiments were especially high and violence was prevalent enough to

make ordinary law enforcement measures insufficient or impossible, military forces governed by

martial law, but only for such time as strictly necessary.83 Although President Lincoln authorized

the suspension of habeas corpus in the North, initially in order to protect troop transport lines but

later more broadly84 to enable the Secretary of State (later the War Department) to order the

arrests of civilians as “prisoners of state,”85 it is not clear that any such persons were considered

enemies or combatants under a law of war rubric.86 On the other hand, it was asserted by

authorities in military law that certain acts in aid of the enemy violated the law of war.87

To address the war and the growing internal security problem, the Lincoln Administration in

September of 1862 proclaimed habeas corpus suspended as to all persons in military custody, and

further proclaimed that all “rebels and insurgents, their aiders and abettors within the United

States, and all persons discouraging volunteer enlistments ... or guilty of any disloyal practice,

affording aid and comfort to rebels against the authority of the United States, shall be subject to

martial law and liable to trial and punishment by courts-martial or military commission.”88 After

Congress authorized the suspension of habeas corpus wherever the President judged it necessary

to public safety,89 President Lincoln reiterated that habeas corpus was suspended as to “prisoners

of war, spies, or aiders or abettors of the enemy” in military custody throughout the United

The district of country declared by the constituted authorities, during the late civil war, to be in

insurrection against the government of the United States, was enemy territory, and all the people

residing within such district were, according to public law, and for all purposes connected with the

prosecution of the war, liable to be treated by the United States, pending the war and while they

remained within the lines of the insurrection, as enemies, without reference to their personal

sentiments and dispositions.

Department did not have the personnel or apparatus to investigate disloyalty charges or conduct arrests on any scale,

and there was no equivalent of today’s Justice Department or FBI. See DANIEL FARBER, LINCOLN’S CONSTITUTION 145

(2003) (noting scarcity of federal law enforcement officers ).

It appears that a number of those arrested were citizens of seceded states, and might have been considered to be in

the position of enemy aliens. For statistics on the residency of persons subject to military arrest in the early days of the

war (when the State Department was charged with internal security), see NEELY, supra footnote 84, at 26-27. Some

States.90 The Lincoln Administration’s approach to internal security, however, was cast in

considerable doubt by the Supreme Court’s decision in Ex parte Milligan.91

Ex Parte Milligan

In 1866, the Supreme Court addressed the question whether a citizen of Indiana who was

allegedly a senior commanding general of the Sons of Liberty,92 an allegedly armed and

organized group of conspirators with links to the Confederate States that planned to commit acts

of sabotage against the North in order to foment rebellion in northwestern states (today’s MidWest),93 could constitutionally be tried by military commission. The Court recognized military

commission jurisdiction over violations of the “laws and usages of war,” but stated those laws

and usages “... can never be applied to citizens in states which have upheld the authority of the

government, and where the courts are open and their process unobstructed.”94 The Supreme Court

explained its reasoning:

It will be borne in mind that this is not a question of the power to proclaim martial law, when

war exists in a community and the courts and civil authorities are overthrown. Nor is it a

question what rule a military commander, at the head of his army, can impose on states in

rebellion to cripple their resources and quell the insurrection .... Martial law cannot arise

from a threatened invasion. The necessity must be actual and present; the invasion real, such

as effectively closes the courts and deposes the civil administration.95

The government had argued in the alternative that Milligan could be held as a prisoner of war “as

if he had been taken in action with arms in his hands,”96 and thus excluded from the privileges of

a proviso to the act authorizing the suspension of habeas corpus, which required courts to free

other persons detained without charge.97 The government argued:

Finally, if the military tribunal has no jurisdiction, the petitioner may be held as a prisoner of

war, aiding with arms the enemies of the United States, and held, under the authority of the

United States, until the war terminates, then to be handed over by the military to the civil

authorities, to be tried for his crimes under the acts of Congress, and before the courts which

he has selected.98

Detention of U.S. Persons as Enemy Belligerents

Milligan, however, argued “that it had been ‘wholly out of his power to have acquired belligerent

rights, or to have placed himself in such relation to the government as to have enabled him to

violate the laws of war,’”99 as he was charged. The Court appears to have agreed with Milligan,

replying:

It is not easy to see how he can be treated as a prisoner of war, when he lived in Indiana for

the past twenty years, was arrested there, and had not been, during the late troubles, a

resident of any of the states in rebellion. If in Indiana he conspired with bad men to assist the

enemy, he is punishable for it in the courts of Indiana; but, when tried for the offence, he

cannot plead the rights of war; for he was not engaged in legal acts of hostility against the

government, and only such persons, when captured, are prisoners of war. If he cannot enjoy

the immunities attaching to the character of a prisoner of war, how can he be subject to their

pains and penalties?100

Milligan was interpreted by some state courts to preclude the trial by military commission of

persons accused of participating in guerrilla activities in Union territory,101 and despite Congress’s

efforts to immunize executive officials for actions done under military authority during the Civil

War,102 the Supreme Court of Illinois upheld damages awarded to Madison Y. Johnson, who,

accused of being “a belligerent” but never charged with any offense, had been confined under

orders issued by the Secretary of War.103 Milligan himself was awarded nominal damages for his

treatment.104

Other “Insurrections”—Moyer v. Peabody

The Supreme Court addressed executive detention of a temporary nature to address less serious

insurrections in 1909 in Moyer v. Peabody.105 The Supreme Court in that case declined to grant

relief to the plaintiff in a civil suit against the governor of Colorado based on the former’s

detention without charge during a miners’ strike (deemed by the governor to be an insurrection),

stating: So long as such arrests are made in good faith and in the honest belief that they are

needed in order to head the insurrection off, the governor is the final judge and cannot be

subjected to an action after he is out of office, on the ground that he had not reasonable ground

for his belief.”106

The Court based its views in part on the laws and constitution of the State of Colorado, which

empowered the governor to repel or suppress insurrections by calling out the militia, which the

that the governor, without sufficient reason, but in good faith, in the course of putting the insurrection down, held the

plaintiff until he thought that he safely could release him.”

Court noted, envisioned the “ordinary use of soldiers to that end; that he may kill persons who

resist, and, of course, that he may use the milder measure of seizing the bodies of those whom he

considers to stand in the way of restoring peace. Such arrests are not necessarily for punishment,

but are by way of precaution, to prevent the exercise of hostile power.”107

The Court further clarified:

If we suppose a governor with a very long term of office, it may be that a case could be

imagined in which the length of the imprisonment would raise a different question. But there

is nothing in the duration of the plaintiff’s detention or in the allegations of the complaint

that would warrant submitting the judgment of the governor to revision by a jury. It is not

alleged that his judgment was not honest, if that be material, or that the plaintiff was detained

after fears of the insurrection were at an end.

Based on the context of the case, the holding may be limited to actual battles and situations of

martial law where troops are authorized to use deadly force as necessary.108 While the Court notes

that “[p]ublic danger warrants the substitution of executive process for judicial process,”109 it also

noted that

[t]his was admitted with regard to killing men in the actual clash of arms; and we think it

obvious, although it was disputed, that the same is true of temporary detention to prevent

apprehended harm. As no one would deny that there was immunity for ordering a company

to fire upon a mob in insurrection, and that a state law authorizing the governor to deprive

citizens of life under such circumstances was consistent with the 14th Amendment, we are of

opinion that the same is true of a law authorizing by implication what was done in this

case.110

It may also be argued that, as a claim for civil damages rather than a direct challenge in the form

of a petition for habeas corpus, the Moyer case does not stand for a general executive authority to

detain indefinitely individuals deemed to be dangerous, but may support temporary detention

during a public emergency. It may be pertinent that the decision interpreted Colorado’s

constitution rather than that of the United States. While some courts have concluded that those

wrongfully detained by order of the President may recover damages from their captors,111 the

modern trend seems to be that damages are not available.112

Detention of U.S. Persons as Enemy Belligerents

World War I

The Alien Enemy Act saw greater use during World War I than in previous wars.113 The statute

grants the President broad authority, during a declared war or presidentially proclaimed

“predatory invasion,” to institute restrictions affecting alien enemies, including possible detention

and deportation. On April 6, 1917, the date Congress declared war against Germany, President

Wilson issued a Proclamation under the Alien Enemy Act warning alien enemies against

violations of the law or hostilities against the United States.114 Offenders would be subject not

only to the applicable penalties prescribed by the domestic laws they violated, but would also be

subject to restraint, required to give security, or subject to removal from the United States under

regulations promulgated by the President.115

The government urged the courts to uphold the constitutionality of the act as a proper exercise of

Congress’s power over the persons and property of alien enemies found on U.S. territory during

war, a power it argued derives from the power of Congress to declare war and make rules

concerning captures on land and water,116 and which was also consistent with the powers residing

in sovereign nations under international law. The law was vital to national security because “[a]n

army of spies, incendiaries, and propagandists may be more dangerous than an army of

soldiers.”117 The President reported to Congress a list of 21 instances of “improper activities of

German officials, agents, and sympathizers in the United States” prior to the declaration of war.118

The government further argued that the statute did not require a hearing prior to internment,

because the power and duty of the President was to act to prevent harm in the context of war,

which required the ability to act based on suspicion rather than only on proven facts.119

While the act would permit regulations affecting all persons within the statutory definition of

alien enemy,120 it was the practice of the United States to apply restrictions only to alien enemies

“Alien Enemy Brief”) (observing that the cases arising under the Alien Enemy Act “contain no expression of doubt by

the courts as to its constitutionality”). In Gilroy, the government argued that the Executive’s determination that an

individual is an enemy alien is final, even though it can be shown that the individual is a citizen. 257 F. at 112. The

court rejected that contention, finding the petitioner was an American citizen and not subject to the Alien Enemy Act.

who were found to constitute an active danger to the state.121 Aliens affected by orders

promulgated under the act did not have recourse to the courts to object to the orders on the

grounds that the determination was not made in accordance with due process of law, but could

bring habeas corpus petitions to challenge their status as enemy aliens.122

In at least two instances, enemy spies or saboteurs entered the territory of the United States and

were subsequently arrested. Pablo Waberski admitted to U.S. secret agents to being a spy sent by

the Germans to “blow things up in the United States.” Waberski, who was posing as a Russian

national, was arrested upon crossing the border from Mexico into the United States and charged

with “lurking as a spy” under article 82 of the Articles of War.123 Attorney General T. W. Gregory

opined in a letter to the President that the jurisdiction of the military to try Waberski by military

tribunal was improper, noting that the prisoner had not entered any camp or fortification, did not

appear to have been in Europe during the war, and thus could not have come through the fighting

lines or field of military operations.124 An ensuing disagreement between the Departments of War

and Justice over the respective jurisdictions of the FBI and military counterintelligence to conduct

domestic surveillance was resolved by compromise.125

Waberski, an officer of the German armed forces whose real name turned out to be Lothar

Witzke, was sentenced to death by a military commission. Subsequently, the new Attorney

General, A. Mitchell Palmer, reversed the earlier AG opinion based on a new understanding of the

facts of the case, including proof that the prisoner was a German citizen and that there were

military encampments close to the area where he was arrested.126 President Wilson commuted

Witzke’s sentence to life imprisonment at hard labor in Fort Leavenworth and later pardoned him,

possibly due to lingering doubts about the propriety of the military tribunal’s jurisdiction to try

the accused spy,127 even though Congress had defined the crime of spying and provided by statute

that it was an offense triable by military commission.128

Detention of U.S. Persons as Enemy Belligerents

challenge his detention by military authorities while he was awaiting court-martial for spying.

The accused was an officer in the German Imperial Navy who used a forged Swiss passport to

enter the United States and operated as an enemy agent in New York City. He was initially

detained as an alien enemy pursuant to a warrant issued in accordance with statute. He contested

his detention on the basis that the port of New York was not in the theater of battle and courts in

New York were open and functioning, arguing Milligan required that he be tried by an Article III

court.130 The court found that its inquiry was confined to determining whether jurisdiction by

court martial was valid, which it answered affirmatively after examining relevant statutes and

finding that, under international law, the act of spying was not technically a crime.131 The court

concluded that the constitutional safeguards available to criminal defendants did not apply, noting

that whoever “joins the forces of an enemy alien surrenders th[e] right to constitutional

protections.” The Supreme Court did not have the opportunity to address the merits of the case,

having dismissed the appeal per stipulation of the parties.132 However, two American citizens who

were alleged to have conspired to commit espionage with Wessels were tried and acquitted of

treason in federal court,133 and subsequently released.

In 1918, a bill was introduced in the Senate to provide for trial by court-martial of persons not in

the military who were accused of espionage, sabotage, or other conduct that could hurt the war

effort.134 The bill had been drafted by Assistant Attorney General Charles Warren, but was

apparently submitted without the approval of the Justice Department.135 The bill asserted that

changes in modern warfare, including use of “civilian and other agents and supporters behind the

lines spreading false statements and propaganda, injuring and destroying the things and utilities”

needed by the Armed Forces, meant that “the United States [now constitutes] a part of the zone of

operations ...”136

In a letter to Representative John E. Raker explaining his opposition to the idea, Attorney General

T.W. Gregory provided statistics about war-related arrests and prosecutions.137 According to the

letter, of 508 espionage cases that had reached a disposition, 335 had resulted in convictions, 31

persons were acquitted, and 125 cases were dismissed.138 Sedition and disloyalty charges had

yielded 110 convictions and 90 dismissals or acquittals.139 Acknowledging that the statistics were

incomplete, the Attorney General concluded that the statistics did not show a cause for concern.140

He also reiterated his position that trial of civilians for offenses committed outside of military

territory by court-martial would be unconstitutional, and attributed the complaints about the

inadequacies of the laws or their enforcement to “the fact that people, under the emotional stress

of the war, easily magnify rumor into fact, or treat an accusation of disloyalty as though it were

Treatment of Enemies During World War II

Ex Parte Quirin

After eight Nazi saboteurs were caught by the Federal Bureau of Investigation (FBI), the

President issued a proclamation declaring that “the safety of the United States demands that all

enemies who have entered upon the territory of the United States as part of an invasion or

predatory incursion, or who have entered in order to commit sabotage, espionage or other hostile

or warlike acts, should be promptly tried in accordance with the law of war.”142 The eight German

saboteurs (one of whom claimed U.S. citizenship) were tried by military commission for entering

the United States by submarine, shedding their military uniforms, and conspiring to use

explosives on certain war industries and war utilities. In the case of Ex parte Quirin, the Supreme

Court denied their writs of habeas corpus (although upholding their right to petition for the writ,

despite language in the Presidential proclamation purporting to bar judicial review), holding that

trial by such a commission did not offend the Constitution and was authorized by statute.143 It

also found the citizenship of the saboteurs irrelevant to the determination of whether the saboteurs

were “enemy belligerents” within the meaning of the Hague Convention and the law of war.144

To reach its decision, the Court applied the international common law of war, as Congress had

incorporated it by reference through Article 15 of the Articles of War,145 and the President’s

proclamation that

[A]ll persons who are subjects, citizens or residents of any nation at war with the United

States or who give obedience to or act under the direction of any such nation, and who

during time of war enter or attempt to enter the United States ... through coastal or boundary

defenses, and are charged with committing or attempting or preparing to commit sabotage,

espionage, hostile or warlike acts, or violations of the law of war, shall be subject to the law

of war and to the jurisdiction of military tribunals.146

Detention of U.S. Persons as Enemy Belligerents

Whether the accused could have been detained as “enemy combatants” without any intent to try

them before a military tribunal was not a question before the Court,147 but the Court suggested the

possibility. It stated:

By universal agreement and practice, the law of war draws a distinction between the armed

forces and the peaceful populations of belligerent nations and also between those who are

lawful and unlawful combatants. Lawful combatants are subject to capture and detention as

prisoners of war by opposing military forces. Unlawful combatants are likewise subject to

capture and detention, but in addition they are subject to trial and punishment by military

tribunals for acts which render their belligerency unlawful.148

In its discussion of the status of “unlawful combatant,” the Court did not distinguish between

enemy soldiers who forfeit the right to be treated as prisoners of war by failing to distinguish

themselves as belligerents, as the petitioners had done, and civilians who commit hostile acts

during war without having the right to participate in combat. Both types of individuals have been

called “unlawful combatants,” yet the circumstances that give rise to their status differ in ways

that may be legally significant.149 However, the Court did recognize that the petitioners fit into the

first category,150 and expressly limited its opinion to the facts of the case:

We have no occasion now to define with meticulous care the ultimate boundaries of the

jurisdiction of military tribunals to try persons according to the law of war. It is enough that

petitioners here, upon the conceded facts, were plainly within those boundaries, and were

held in good faith for trial by military commission, charged with being enemies who, with

the purpose of destroying war materials and utilities, entered or after entry remained in our

territory without uniform—an offense against the law of war. We hold only that those

particular acts constitute an offense against the law of war which the Constitution authorizes

to be tried by military commission.151

The Supreme Court distinguished its holding from Milligan, finding that the Quirin petitioners

were enemy belligerents and that the charge made out a valid allegation of an offense against the

law of war for which the President was authorized to order trial by a military commission.152

It seems clear that the Quirin Court did not intend to overrule Milligan, but the distinction

between the two cases may seem puzzling to those familiar with Civil War history.153 The Quirin

Court characterized Milligan in a way that seemed to minimize the nature of the allegations

involved, calling Milligan a civilian who “was not engaged in legal acts of hostility against the

At oral argument before the Supreme Court, Attorney General Biddle suggested that had the prisoners been captured

by the military rather than arrested by the FBI, the military could have detained them “in any way they wanted,”

without any arraignment or any sort of legal proceeding. See 39 LANDMARK BRIEFS AND ARGUMENTS OF THE SUPREME

COURT OF THE UNITED STATES 597 (Philip B. Kurland and Gerhard Casper, eds. 1975).

government.”154 Yet Milligan was in fact alleged to have engaged in hostile and warlike acts. The

Quirin Court also noted the distinction that Milligan, “not being a part of or associated with

armed forces of the enemy,” was a civilian rather than an enemy combatant, without mentioning

that the government had argued that Milligan was allegedly part of a group that was associated

with the Confederate Army.155

Reconciling the facts of Milligan with the Quirin Court’s description of them is possible by

applying a formal understanding of the concept of war as distinguished from a lesser insurrection.

Under this view, the key distinction appears to be that Milligan’s activity could not be

characterized as legal acts of hostility because Milligan was not a lawful combatant belonging to

Confederate forces.156 Any contention between the Sons of Liberty and the Union apparently did

not amount to “hostilities” in the legal sense. The Quirin opinion, read together with Milligan,

appears to regard the “legal” nature of the acts to be based on the petitioner’s association with a

legitimate belligerent party rather than the nature of the acts. Milligan’s membership in the Sons

of Liberty did not secure his legitimacy as a belligerent, but neither did it give the government the

right to detain him as a prisoner of war.157 The Sons of Liberty, it seems, did not qualify as a

belligerent for the purposes of the law of war, even though it was alleged to be plotting hostile

acts on behalf of the Confederacy and it communicated with Confederate agents.158 The Quirin

Court noted with apparent approval several Civil War cases in which enemy belligerents were

tried by military commission for hostile acts conducted in the North, but the Court was careful to

mention in each case that the defendant held a Confederate commission or was otherwise enrolled

in or employed by Confederate forces.159 Omitted from the Court’s survey of cases were those

suggested by the government in its brief that involved nonmembers of Confederate forces,

154

See 4 Wall. (71 U.S.) at 131.

155

According to the record, evidence showed that Milligan was a member of

a powerful secret association, composed of citizens and others, [that] existed within the state, under

military organization, conspiring against the draft, and plotting insurrection, the liberation of the

prisoners of war at various depots, the seizure of the state and national arsenals, armed cooperation

with the enemy, and war against the national government.

4 Wall. (71 U.S.) at 141 (Chase, C.J., concurring). Four Justices concurred in the decision but took the position that

under the circumstances, Congress could have constitutionally authorized military tribunals to try civilians, but had “by

the strongest implication” prohibited them.

156

For a discussion that may shed light on the understanding of the term “legal hostilities,” see HENRY W. HALLECK,

INTERNATIONAL LAW, OR, RULES REGULATING THE INTERCOURSE OF STATES IN PEACE AND WAR 411-12 (1878):

[A] war ... is not confined to the governments or authorities of the belligerent state, but that it

makes all the subjects of the one state the legal enemies of each and every subject of the other. This

hostile character results from political ties, and not from personal feelings or personal antipathies;

their status is that of legal hostility, and not of personal enmity. So long as these political ties

continue, or so long as the individual continues to be the citizen or subject of one of the belligerent

states, just so long does he continue in legal hostility toward all the citizens and subjects of the

opposing belligerent.

belligerents”).

Detention of U.S. Persons as Enemy Belligerents

including Milligan and his co-defendants as well as the persons tried for Lincoln’s assassination

in 1865.160

Although the opinion is cryptic on this point, the important distinction in Quirin seems to be the

nature and status of the enemy forces of which Milligan was allegedly a member, rather than

whether he was associated with any hostile force at all. The petitioners in Quirin were all

conceded to be engaging in hostilities under the direction of the armed forces of an enemy State

in a declared war (although perhaps not formally enrolled in its military). What association with

the enemy short of this might have brought the saboteurs under military jurisdiction is unclear.

The fact that Milligan’s membership in an organization with ties to the Confederate government

(although not claimed to be operating under Confederate direction) was ruled insufficient to make

him a belligerent within the meaning of the law of war might have some bearing on the

interpretation of the term “associated forces” in the NDAA definition of persons susceptible to

detention without trial under the law of war.

Another point of distinction was that Milligan had not traveled from enemy territory into friendly

territory, while the Quirin petitioners were described as having crossed military lines of defense

to enter the country surreptitiously.161 This apparently stems from the long-standing concept

under the law of war that permits the armed forces of a belligerent to punish those who cross

defensive lines and act as spies,162 whereas the same activity conducted in contested territory

would not deprive the accused of prisoner of war status.

The continuing validity of Milligan has been questioned by some scholars, even though the

Quirin Court declined to overrule it, while others assert that the essential meaning of the case has

only to do with situations of martial law or, perhaps, civil wars. Furthermore, it has been noted

that the portion of the plurality in Milligan asserting that Congress could not constitutionally

authorize the President to use the military to detain and try civilians may be considered dicta with

correspondingly less precedential value, inasmuch as Congress had implicitly denied such

authority. However, the Hamdi Court, in distinguishing Milligan from Hamdi, placed emphasis

on the fact that Milligan was not considered a prisoner of war, suggesting that it may recognize

the distinction between Milligan and Quirin as a function of combatant status.

associates, the trial of Clement Vallandigham for expressing sympathies with the Confederacy, and the case of George

St. Leger Grenfel and other civilians who were convicted of conspiring to free rebel prisoners of war from a prison in

Chicago and then burn the city as a part of an alleged plot with the Sons of Liberty). St. Leger Grenfel was a Britishborn former colonel in the Confederate army, but was apparently retired and therefore considered a civilian. He made a

jurisdictional argument similar to the one that ultimately prevailed in Milligan, but did not challenge the authority of

entitled to the status of prisoners of war, but to be offenders against the law of war subject to trial

and punishment by military tribunals.

Detention of U.S. Persons as Enemy Belligerents

The Hamdi Court found that Milligan did not apply to a U.S. citizen captured in Afghanistan.

Justice O’Connor wrote that Milligan:

does not undermine our holding about the Government’s authority to seize enemy

combatants, as we define that term today. In that case, the Court made repeated reference to

the fact that its inquiry into whether the military tribunal had jurisdiction to try and punish

Milligan turned in large part on the fact that Milligan was not a prisoner of war, but a

resident of Indiana arrested while at home there. That fact was central to its conclusion. Had

Milligan been captured while he was assisting Confederate soldiers by carrying a rifle

against Union troops on a Confederate battlefield, the holding of the Court might well have

been different. The Court’s repeated explanations that Milligan was not a prisoner of war

suggest that had these different circumstances been present he could have been detained

under military authority for the duration of the conflict, whether or not he was a citizen.163

In Re Territo

In the case In re Territo,164 an American citizen who had been inducted into the Italian army was

captured during battle in Italy and transferred to a detention center for prisoners of war in the

United States. He petitioned for a writ of habeas corpus, arguing that his U.S. citizenship

foreclosed his being held as a POW. The court disagreed, finding that citizenship does not

necessarily “affect[] the status of one captured on the field of battle.”165 The court stated: “Those

who have written texts upon the subject of prisoners of war agree that all persons who are active

in opposing an army in war may be captured and except for spies and other non-uniformed

plotters and actors for the enemy are prisoners of war.”166

The petitioner argued that the Geneva Convention did not apply in cases such as his. The court

found no authority in support of that contention, noting that “[i]n war, all residents of the enemy

country are enemies.”167 The court also cited approvingly the following passage: “A neutral, or a

citizen of the United States, domiciled in the enemy country, not only in respect to his property

but also as to his capacity to sue, is deemed as much an alien enemy as a person actually born

under the allegiance and residing within the dominions of the hostile nation.”168

While recognizing that Quirin was not directly in point, it found the discussion of U.S. citizenship

to be “indicative of the proper conclusion”: “Citizens who associate themselves with the military

arm of the enemy government, and with its aid, guidance and direction enter this country bent on

hostile acts are enemy belligerents within the meaning of the Hague Convention and the law of

war.”169

because it was necessary to determine whether Milligan came within the statutory provision requiring all those not held

as prisoners of war to be released unless charged. He would have found that there is no exception to the right to trial by

jury even for citizens who could be called “belligerents” or “prisoners of war.” Id.

Detention of U.S. Persons as Enemy Belligerents

The court had no occasion to consider whether a citizen who becomes associated with an armed

group not affiliated with an enemy government and not otherwise covered under the terms of the

Hague Convention could be detained without charge pursuant to the law of war,170 particularly

those not captured by the military during battle.

Confining the Territo and Quirin opinions to their facts, they may not provide a solid foundation

for the detention of U.S. citizens captured within the United States as enemy combatants. It may

be argued that the language referring to the capture and detention of unlawful combatants—

seemingly without indictment on criminal charges—is dicta; the petitioners in those cases did not

challenge the contention that they served in the armed forces of an enemy state with which the

United States was engaged in a declared war. We are unaware of any U.S. precedent confirming

the constitutional power of the President to detain indefinitely a person accused of being an

unlawful combatant due to mere membership in or association with a group that does not qualify

as a legitimate belligerent, with or without the authorization of Congress.171 The Supreme Court

rejected a similar contention in Milligan, where Congress had limited the authority to detain

persons in military custody.

At most, arguably, the two cases above may be read to demonstrate that, at least in the context of

a declared war against a recognized state, U.S. citizenship is not constitutionally relevant to the

treatment of members of enemy forces under the law of war.172 Given that the Hague convention

applies only to conflicts where belligerents meet the same qualifications that were later

incorporated into Article 4 of the Third Geneva Convention for prisoner of war status, it seems

clear that the Hague Convention would not apply to the conflict with Al Qaeda or perhaps the

Taliban for the same reasons that were given to preclude their treatment as prisoners of war.173

Because the status of the relevant armed conflict under international law appears to have been

To conduct their operations in accordance with the laws and customs of war.

as nations).

172

A majority of the Supreme Court in Hamdi appears to have agreed that Quirin establishes that U.S. citizenship is

irrelevant in the treatment of captured enemies, at least those captured overseas in a conflict to which the Geneva

Conventions apply. Hamdi v. Rumsfeld, 542 U.S. 507, 519 (2004) (O’Connor, J., plurality opinion) (“Citizens who

Detention of U.S. Persons as Enemy Belligerents

important to the resolution of the Civil War and World War II detainee cases, it is perhaps

unwarranted to presume that Territo and Quirin are apposite to a conflict that does not amount to

an international armed conflict.174

Internment of Enemy Civilians

During the Second World War, President Roosevelt made numerous proclamations under the

Alien Enemy Act for the purpose of interning aliens from enemy countries deemed dangerous or

likely to engage in espionage or sabotage.175 At the outset of the war, the internments were

effected under civil authority of the Attorney General, who established “prohibited areas” in

which no aliens of Japanese, Italian, or German descent were permitted to enter or remain, as well

as a host of other restraints on affected aliens. The President, acting under statutory authority,

delegated to the Attorney General the authority to prescribe regulations for the execution of the

program. Attorney General Francis Biddle created the Alien Enemy Control Unit to review the

recommendations of hearing boards handling the cases of the more than 2,500 enemy aliens in the

temporary custody of the Immigration and Naturalization Service (INS).176

In February of 1942, the President extended the program to cover certain citizens177 as well as

enemy aliens, and turned over the authority to prescribe “military areas” to the Secretary of War,

who further delegated the responsibilities under the order with respect to the west coast to the

Commanding General of the Western Defense Command. The new order, Executive Order

9066,178 clearly amended the policy established under the earlier proclamations regarding aliens

and restricted areas, but did not rely on the authority of Alien Enemy Act, as the previous

proclamations had done.179 Although the Department of Justice denied that the transfer of

authority to the Department of War was motivated by a desire to avoid constitutional issues with

regard to the restriction or detention of citizens, the House Select Committee Investigating

National Defense Migration found the shift in authority significant, as it appeared to rely on the

nation’s war powers directly, and could find no support in the Alien Enemy Act with respect to

citizens.180 The summary exercise of authority under that act to restrain aliens was thought by the

Detention of U.S. Persons as Enemy Belligerents

Committee to be untenable in the case of U.S. citizens, and the War Department felt

congressional authorization was necessary to provide authority for its enforcement.181

Congress granted the War Department’s request, enacting with only minor changes the proposed

legislation providing for punishment for the knowing violation of any exclusion order issued

pursuant to Executive Order 9066 or similar executive order.182 A policy of mass evacuation from

the West Coast of persons of Japanese descent—citizens as well as aliens—followed, which soon

transformed into a system of compulsive internment at “relocation centers.”183 Persons of German

and Italian descent (and others) were treated more selectively, receiving prompt (though probably

not full and fair) loyalty hearings184 to determine whether they should be interned, paroled, or

released. The disparity of treatment was explained by the theory that it would be impossible or

too time-consuming to attempt to distinguish the loyal from the disloyal among persons of

Japanese descent.185

In a series of cases, the Supreme Court limited, but did not explicitly strike down the internment

program. In the Hirabayashi case, the Supreme Court found the curfew imposed upon persons of

Japanese ancestry to be constitutional as a valid war-time security measure, even as implemented

against U.S. citizens, emphasizing the importance of congressional ratification of the Executive

Order.186 Hirabayashi was also indicted for violating an order excluding him from virtually the

entire west coast, but the Court did not review the constitutionality of the exclusion measure

because the sentences for the two charges were to run concurrently.187 Because the restrictions

affected citizens solely because of their Japanese descent, the Court framed the relevant inquiry as

a question of equal protection, asking

whether in the light of all the facts and circumstances there was any substantial basis for the

conclusion, in which Congress and the military commander united, that the curfew as

applied was a protective measure necessary to meet the threat of sabotage and espionage

which would substantially affect the war effort and which might reasonably be expected to

aid a threatened enemy invasion.188

In a concurring opinion, Justice Douglas added that in effect, due process considerations did not

apply to ensure that only individuals who were actually disloyal were affected by the restrictions,

even if it were to turn out that only a small percentage of Japanese-Americans were actually

disloyal.189 However, he noted that a more serious question would arise if a citizen did not have

Detention of U.S. Persons as Enemy Belligerents

an opportunity at some point to demonstrate his loyalty in order to be reclassified and no longer

subject to the restrictions.190

In Korematsu,191 the Supreme Court upheld the conviction of an American citizen for remaining

in his home despite the fact that it was located on a newly declared “Military Area” and was thus

off-limits to persons of Japanese descent. Fred Korematsu also challenged the detention of

Japanese-Americans in internment camps, but the Court declined to consider the constitutionality

of the detention itself, as Korematsu’s conviction was for violating the exclusion order only. The

Court, in effect, validated the treatment of citizens in a manner similar to that of enemy aliens by

reading Executive Order 9066 together with the act of Congress ratifying it as sufficient authority

under the combined war powers of the President and Congress, thus avoiding having to address

the statutory scope of the Alien Enemy Act.

In Ex parte Endo,192 however, decided the same day as Korematsu, the Supreme Court did not

find adequate statutory underpinnings to support the internment of loyal citizens. The Court ruled

that the authority to exclude persons of Japanese ancestry from declared military areas did not

encompass the authority to detain concededly loyal Americans. Such authority, it found, could not

be implied from the power to protect against espionage and sabotage during wartime.193 The

Court declined to decide the constitutional issue presented by the evacuation and internment

program, instead interpreting the executive order, along with the Act of March 27, 1942

(congressional ratification of the order),194 narrowly to give it the greatest chance of surviving

constitutional review.195 Accordingly, the Court noted that detention in Relocation Centers was

not mentioned in the statute or executive order, but was developed during the implementation of

the program. As such, the authority to detain citizens could only be found by implication in the

act, and must therefore be found to serve the ends Congress and the President had intended to

reach. The Court declared its obligation to interpret the wartime measure to allow for the

“greatest possible accommodation between ... liberties and the exigencies of war,” which in turn

required an assumption that Congress “intended to place no greater restraint on the citizen than

was clearly and unmistakably indicated by the language they used.”196

The Court avoided the question of whether internment of citizens would be constitutionally

permissible where loyalty was at issue or where Congress explicitly authorized it, but the Court’s

use of the term “concededly loyal” to limit the scope of the finding may be read to suggest that

there is a Fifth Amendment guarantee of due process applicable to a determination of loyalty or

dangerousness. While the Fifth Amendment would not require the same process that is due in a

criminal case, it would likely require at least reasonable notice of the allegations and an

opportunity for the detainee to be heard.

At least one American with no ethnic ties to or association with an enemy country was subjected

to an exclusion order issued pursuant to Executive Order 9066. Homer Wilcox, a native of Ohio,

was excluded from his home in San Diego and removed by military force to Nevada, although the

exclusion board had determined that he had no association with any enemy and was more aptly

described as a “harmless crackpot.”197 He was the manager of a religious publication that

preached pacifism, and was indicted along with several others for fraud in connection with the

publication.198 The district court awarded damages in favor of Wilcox, but the circuit court

reversed, finding the exclusion within the authority of the military command under Executive

Order 9066 and 18 U.S.C. Section 1383, and holding that

the evidence concerning plaintiff’s activities and associations provided a reasonable ground

for the belief by defendant ... that plaintiff had committed acts of disloyalty and was engaged

in a type of subversive activity and leadership which might instigate others to carry out

activities which would facilitate the commission of espionage and sabotage and encourage

them to oppose measures taken for the military security of Military Areas Nos. 1 and 2, and

that plaintiff’s presence in the said areas from which he had been excluded would increase

the likelihood of espionage and sabotage and would constitute a danger to military security

of those areas.199

The court also found that the act of Congress penalizing violations of military orders under

Executive Order 9066 did not preclude General De Witt from using military personnel to forcibly

eject Wilcox from his home.200

The Japanese internment program has since been widely discredited,201 the convictions of some

persons for violating the orders have been vacated,202 and the victims have received

compensation,203 but the constitutionality of detention of citizens during war who are deemed

dangerous has never expressly been ruled per se unconstitutional.204 In the cases of citizens of

other ethnic backgrounds who were interned or otherwise subject to restrictions under Executive

Order 9066, courts played a role in determining whether the restrictions were justified, sometimes

resulting in the removal of restrictions.205 Because these persons were afforded a limited hearing

to determine their dangerousness, a court later ruled that the Equal Protection Clause of the

Constitution did not require that they receive compensation equal to that which Congress granted

in 1988 to Japanese-American internees.206

Detention of U.S. Persons as Enemy Belligerents

It may be argued that Hirabayashi and the other cases validating Executive Order 9066 (up to a

point) support the constitutionality of preventive detention of citizens during war, at least insofar

as the determination of dangerousness of the individual interned is supported by some evidence

and some semblance of due process is accorded the internee. However, it may bear emphasis that

a congressional declaration of war alone was not enough to support the President’s actions.

Instead, it was emphasized in these cases that Congress had specifically ratified Executive Order

9066 by enacting 18 U.S.C. Section 1383, providing a penalty for violation of military orders

issued under the Executive Order. Thus, even though the restrictions and internments occurred in

the midst of a declared war, a presidential order coupled with specific legislation appears to have

been required to validate the measures. The internment of Japanese-American citizens without

individualized determination of dangerousness was found not to be authorized by the Executive

Order and ratifying legislation (the Court thereby avoiding the constitutional issue), although the

President had issued a separate Executive Order to set up the War Relocation Authority207 and

Congress had given its tacit support for the internments by appropriating funds for the effort.208

The only persons who were treated as enemy combatants pursuant to Proclamation No. 2561209

were members of the German military who had been captured after landing on U.S. beaches from

German submarines.210 Collaborators and persons who harbored such saboteurs were tried in

federal courts for treason or violations of other statutes.211 Hans Haupt, the father of one of the

saboteurs, was sentenced to death for treason, but this sentence was overturned on the ground that

procedures used during the trial violated the defendant’s rights.212 On retrial, Haupt was sentenced

to life imprisonment, but his sentence was later commuted on the condition that he leave the

country. Another person charged with treason for his part in the saboteurs’ conspiracy, Helmut

Leiner, was acquitted of treason but then interned as an enemy alien.213 Anthony Cramer, an

American citizen convicted of treason for assisting one of the saboteurs to carry out financial

transactions, had his conviction overturned by the Supreme Court on the grounds that the overt

acts on which the charge was based were insufficient to prove treason.214 Emil Krepper, a pastor

living in New Jersey, came under suspicion because his name was found printed in secret ink on

the saboteur’s handkerchief, although he never met with any of the saboteurs. He was indicted for

Proclamation No. 2561, of July 2, 1942, 7 Federal Register 5101, 56 Stat. 1964. Like Exec. Order No. 9066 issued

earlier that same year, Proc. 2561 retained terminology from the Alien Enemy Act but did not explicitly rely on it for

authority. However, during oral argument before the Supreme Court, the Attorney General placed some emphasis on

the fact that the Proclamation was consistent with the Alien Enemy Act as well as the Articles of War, and was thus

authorized by Congress. See LANDMARK BRIEFS, supra note 39, at 594-95.

activity as a foreign agent.215

These cases involving collaborators with the Quirin eight, as well as other unrelated cases of

sabotage or collaboration with the enemy during World War II, did not result in any military

determinations that those accused were enemy combatants or could be subjected to military

detention until the end of hostilities.216 It is thus not clear what kind of association with Germany

or with other enemy saboteurs, short of actually belonging to the German armed forces, might

have enabled the military to detain any of them as enemy combatants under the law of war.217 It

appears that Quirin was not interpreted at the time as having established executive authority to

detain persons based solely on their alleged hostile intent, particularly without any kind of a trial.

After the Quirin decision, the Attorney General asked Congress to pass legislation to strengthen

criminal law relating to internal security during wartime.218 Attorney General Biddle wrote that

new law was necessary to cover serious gaps and inadequacies in criminal law, which he argued

did not provide sufficient punishment for hostile enemy acts perpetrated on the territory of the

215

See Krepper Guilty as Spy, NY TIMES, March 15, 1945, at 25.

Other Americans who were employed by enemy governments overseas were also tried for treason in federal court;

there is nothing in the cases to indicate that the courts or the prosecutors believed that the defendants could be treated

as enemy combatants under the law of war. See Kawakita v. United States, 343 U. S. 717 (1952) (civilian interpreter

with private munitions company in Japan who mistreated prisoners of war employed in munitions production);

Chandler v. United States, 171 F.2d 921 (1st Cir. 1948), cert. denied, 336 U. S. 918 (1949) (American engaged by

States, 192 F.2d 338 (9th Cir. 1951), cert. denied, 343 U. S. 935 (1952) (radio broadcasting for Japanese government

under the name “Tokyo Rose”). Those who were arrested and detained by the military overseas were apparently

considered to have the status of civilians who pose a danger to the occupying armed forces rather than combatants or

prisoners of war. See D’Aquino, 192 F.2d at 355:

While open warfare had ceased, the security of the occupation forces was a continuing problem

confronting the military commanders. Appellant was a suspected traitor. That she might be capable

of fomenting disorder among the Japanese population then being subjected to the yoke of military

occupation, and of inciting discontent among the troops of the occupying powers was a sufficient

basis for the military to take the precautionary measure of interning appellant. The paramount

interest of the occupation force is its own security. We see no abuse of military discretion in the

protection of that interest. We hold that the confinement was within the constitutional sanction of

the war power; the restraint was legal.

Although the war power was invoked to validate detention by military forces overseas, the cases do not appear to

establish that military detention outside of a situation of military occupation is an authority implicit in a declaration of

war.

H.Rept. 78-219 (1943) (describing Justice Department proposal introduced in previous Congress as H.R. 7737, then

“hostile acts against the United States” if committed with the intent to aid a country with which the United States was

at war, to include sabotage, espionage, harboring or concealing an agent or member of the armed forces of an enemy

state, or entering or leaving the United States with the intent of providing aid to the enemy. It also would have made it a

criminal offense to fail to report information giving rise to probable cause to believe that another has committed, is

committing or plans to commit a hostile act against the United States. Id. at 11. Title II of the act would have modified

court procedure in cases involving these “hostile acts” as well as certain other statutes, that would have allowed the

Attorney General to certify the importance of a case to the war effort, resulting in expedited proceedings, enhanced

secrecy for such proceedings, and a requirement for the approval of a federal judge to release the accused on bail. The

act was not intended to affect the jurisdiction of military tribunals and did not cover uniformed members of the enemy

acting in accordance with the law of war. Id. at 12.

Detention of U.S. Persons as Enemy Belligerents

United States.219 The House Committee on the Judiciary endorsed the proposed War Security Act,

pointing to the fact that it had been necessary to try the eight Nazi saboteurs by military

commission due to the inadequacy of the penal code to punish the accused for acts that had not

yet been carried out.220 It also suggested that military jurisdiction might be unavailable to try

enemy saboteurs who had not “landed as part of a small invasion bent upon acts of illegal

hostilities.”221 The bill passed in the House of Representatives, but was not subsequently taken up

in the Senate.

The Cold War

After the close of World War II, Congress turned its attention to the threat of communism.

Recognizing that the Communist Party presented a different kind of threat from that of a strictly

military attack, Members of Congress sought to address the internal threat with innovative

legislation.222

The Emergency Detention Act

Introduced in the wake of the North Korean attack on South Korea, the Internal Security Act

(ISA) of 1950223 was the culmination of many legislative efforts to provide means to fight what

was viewed as a foreign conspiracy to infiltrate the United States and overthrow the government

by means of a combination of propaganda, espionage, sabotage, and terrorist acts.224 The Attorney

General presented to the Congress a draft bill that would strengthen the espionage statutes, amend

the Foreign Agents Registration Act, and provide authority for U.S. intelligence agencies to

intercept communications.225 According to the Attorney General, the legislation was necessary

because “[t]he swift and more devastating weapons of modern warfare coupled with the

treacherous operations of those who would weaken our country internally, preliminary to and in

conjunction with external attack, have made it imperative that we strengthen and maintain an alert

and effective peacetime vigilance.”226

219

See id. at 1-2 (letter from Attorney General to the House of Representatives dated October 17, 1942).

See id. at 5 (stating that the maximum criminal punishment for a conspiracy to commit sabotage would have been

only two years).

221

See id; see also 1942 ATT’Y GEN. ANN. REP. 13. This view was echoed during floor debate of the proposed act in the

House of Representatives. Supporters and detractors of the bill alike seemed to agree that the military tribunal upheld in

Ex parte Quirin was an extraordinary measure that was constitutionally permissible only because the saboteurs had

come “wearing German uniforms” and thus were “subject to be prosecuted under military law.” See 89 CONG. REC.

2780 - 82 (1943) (remarks by Reps. Michener, Rankin, and Kefauver). There does not appear to be any suggestion that

Quirin could be interpreted to authorize the detention without trial of individuals suspected of hostile intent by

designating them to be unlawful enemy combatants.

Detention of U.S. Persons as Enemy Belligerents

S. 4037 combined the proposed legislation with other bills related to national security, including

measures to exclude and expel subversive aliens, detain or supervise aliens awaiting deportation,

and deny members of communist organizations the right to travel on a U.S. passport. The bill also

contained a requirement for Communist-controlled organizations and Communist-front

organizations to register as such.227 President Truman and opponents of the so-called McCarran

Act thought the registration requirements and other provisions likely to be either unconstitutional

or ineffective, and expressed concern about possible far-reaching civil liberties implications.228

Opponents of the McCarran Act sought to substitute a new bill designed to address the security

concerns in what they viewed as a more tailored manner. Senator Kilgore introduced the

Emergency Detention Act229 (Kilgore bill) to authorize the President to declare a national

emergency under certain conditions, during which the Attorney General could adopt regulations

for the preventive incarceration of persons suspected of subversive ties. At the time of the debate,

18 U.S.C. Section 1383 was still on the books and would have ostensibly supported the

declaration of military areas and the enforcement of certain restrictions against aliens or citizens

deemed dangerous. Proponents of the Kilgore bill argued that the proposed legislation would

create a program for internment of enemies that would contain sufficient procedural safeguards to

render it invulnerable to court invalidation based on Ex parte Endo.230

The final version of the ISA contained both the McCarran Act and the Emergency Detention Act.

President Truman vetoed the bill, voicing his continued opposition to the McCarran Act. The

President did not take a firm position with regard to the Emergency Detention Act, stating that

it may be that legislation of this type should be on the statute books. But the provisions in

[the ISA] would very probably prove ineffective to achieve the objective sought, since they

would not suspend the writ of habeas corpus, and under our legal system to detain a man not

charged with a crime would raise serious constitutional questions unless the writ of habeas

corpus were suspended.231

The President recommended further study on the matter of preventive detention for national

security purposes. Congress passed the ISA over the President’s veto.232

same time, it appears that the FBI had compiled a list of dangerous persons whom it planned to detain in the event of a

national security, in which case the Administration hoped to obtain congressional ratification and a suspension of the

Writ of Habeas Corpus. See Final Report of the Select Committee to Study Governmental Operations with Respect to

Intelligence Activities 436-38, S.Rept. 94-755, 94th Cong., 2d Sess. (1976). President Truman’s staff advised him that

Detention of U.S. Persons as Enemy Belligerents

The Emergency Detention Act, Title II of the ISA, authorized the President to declare an “Internal

Security Emergency” in the event of an invasion of the territory of the United States or its

possessions, a declaration of war by Congress, or insurrection within the United States in aid of a

foreign enemy, where the President deemed implementation of the measures “essential to the

preservation, protection and defense of the Constitution.”233 The act authorized the maintenance

of the internment and prisoner-of-war camps used during World War II for use during subsequent

crises, and authorized the Attorney General, during national emergencies under the act, to issue

warrants for the apprehension of “those persons as to whom there is a reasonable ground to

believe that such persons probably will engage in, or conspire to engage in acts of sabotage or

espionage.” Detainees were to be taken before a preliminary hearing officer within 48 hours of

their arrest, where each detainee would be informed of the grounds for his detention and of his

rights, which included the right to counsel, the privilege against self-incrimination, the right to

introduce evidence and cross-examine witnesses.234 The Attorney General was required to present

evidence to the detainee and to the hearing officer or board “to the fullest extent possible

consistent with national security.”235 Evidence that could be used to determine whether a person

could be detained as dangerous included evidence that a person received training from or had

ever committed or conspired to commit espionage or sabotage on behalf of an entity of a foreign

Communist party or the Communist Party of the United States, or any other group that seeks the

overthrow of the government of the United States by force.236

The Non-Detention Act

No internal emergencies were declared pursuant to the Emergency Detention Act, despite the

United States’ involvement in active hostilities against Communist forces in Korea and Vietnam

and the continued suspicion regarding the existence of revolutionary and subversive elements

within the United States.237 Nevertheless, the continued existence of the act aroused concern

among many citizens, who believed the act could be used as an “instrumentality for apprehending

and detaining citizens who hold unpopular beliefs and views.”238 Several bills were introduced to

amend or repeal the act.239 The Justice Department supported the repeal of the act, opining that

the potential advantage offered by the statute in times of emergency was outweighed by the

Communist and black nationalist elements which are planning and organizing guerrilla-type operations against the

United States.” The Committee concluded that “[a]cts of overt violence by the guerrillas would mean that they had

declared a ‘state of war’ within the country and, therefore, would forfeit their rights as in wartime. The McCarran Act

provides for various detention centers to be operated throughout the country and these might be utilized for the

temporary imprisonment of warring guerrillas.” Id. at 59.

race). According to the Justice Department, the rumors that a system of concentration camps existed was likely

found to be a Communist-front organization that aimed to nullify the ISA. Id. at 9. H.R. 19163 would have amended
