The War Crimes Act: Current Issues
Summary
The War Crimes Act of 1996, as amended, makes it a criminal offense to
commit certain violations of the laws of war when such offenses are committed by
or against U.S. nationals or Armed Service members. Among other things, the act
prohibits certain violations of Common Article 3 of the 1949 Geneva Conventions,
which sets out minimum standards for the treatment of detainees in armed conflicts
of a non-international character. Common Article 3 prohibits protected persons from
being subjected to violence, outrages upon personal dignity, torture, and cruel,
humiliating, or degrading treatment. In the 2006 case of Hamdan v. Rumsfeld, the
Supreme Court rejected the Bush Administration’s long-standing position that
Common Article 3 was inapplicable to the present armed conflict with Al Qaeda. As
a result, questions have arisen regarding the scope of the War Crimes Act as it relates
to violations of Common Article 3 and the possibility that U.S. personnel may be
prosecuted for the pre-Hamdan treatment of Al Qaeda detainees.
As amended by the Military Commissions Act of 2006 (MCA, P.L. 109-366),
the War Crimes Act now criminalizes only specified Common Article 3 violations
labeled as “grave breaches.” Previously, any violation of Common Article 3
constituted a criminal offense. This report discusses current issues related to the War
Crimes Act.

The War Crimes Act:
Current Issues
The 1949 Geneva Conventions proscribe certain conduct by High Contracting
Parties toward specified categories of vulnerable persons during armed conflict.1
High Contracting Parties are also required to provide effective penal sanctions
against any person who commits (or orders the commission of) a “grave breach” of
one of the Conventions, which is defined to include the wilful killing, torture or
inhuman treatment, and the causing of great suffering or serious injury to body or
health of protected persons.2 Congress approved the War Crimes Act of 1996 (P.L.
104-192) specifically to implement the Conventions’ penal requirements.3
The War Crimes Act (18 U.S.C. § 2441)
The War Crimes Act imposes criminal penalties against persons who commit
certain offenses under the laws of war, when those offenses are either committed by
or against a U.S. national or member of the U.S. Armed Forces. The act applies
regardless of whether the offense occurs inside or outside the United States.
Offenders are subject to imprisonment for life or any term of years and may receive
the death penalty if their offense results in death to the victim.
At the time of enactment, the War Crimes Act only covered grave breaches of
the 1949 Geneva Conventions. During congressional deliberations, the Departments
of State and Defense suggested the act be crafted to cover additional war crimes, but

Armed Forces in the Field, 6 U.S.T. 3114; Geneva Convention for the Amelioration of the
Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea, 6 U.S.T.
3217; Geneva Convention Relative to the Treatment of Prisoners of War, 6 U.S.T. 3316
[hereinafter “Third Geneva Convention”]; Geneva Convention Relative to the Protection
of Civilian Persons in Time of War, 6 U.S.T. 3516. All four Conventions entered into force
for the United States on February 2, 1956.

3 When the Conventions were ratified in 1955, the Senate Foreign Relations Committee
believed that the obligations imposed by the Conventions’ “grave breach” provisions were
met by existing federal law and no further legislation was required. H.Rept. 104-698, at 3-4
(1996) (quoting Sen. Exec. Rep. No. 9, at 27 (1955)). However, in 1996 the House
Committee on the Judiciary found that in some cases the United States was legally unable
to prosecute persons for the commission of grave breaches of the Conventions, including
when members of the armed forces were found to have committed war crimes only after
their military discharge. Id. at 5.

these recommendations were not immediately followed.4 However, Congress
amended the War Crimes Act the following year to cover additional war crimes that
had been suggested by the State and Defense Departments, including violations under
Article 3 of any of the 1949 Geneva Conventions (Common Article 3). Common
Article 3 is applicable to armed conflicts “not of an international character” and
covers persons taking no active part in hostilities, including those who have laid
down their arms or been incapacitated by capture or injury. Such persons are to be
treated humanely and protected from certain treatment, including “violence to life
and person,” “cruel treatment and torture,” and “outrages upon personal dignity, in
particular, humiliating and degrading treatment.”
Implications of Hamdan v. Rumsfeld
There has been controversy concerning whether activities by military and
intelligence personnel relating to captured Al Qaeda suspects might give rise to
prosecution under the War Crimes Act, particularly in light of the Supreme Court’s
ruling in the 2006 case of Hamdan v. Rumsfeld.5 The following sections provide
relevant background and briefly discuss possible implications that the Court’s ruling
may have on issues relating to the War Crimes Act.
Application of Common Article 3 to Al Qaeda. At least since early 2002,
the Bush Administration had taken the position that the Geneva Conventions did not
apply to members of Al Qaeda. Specifically, the Administration argued that the
Conventions were applicable to international armed conflicts between High
Contracting Parties and States that abide by Convention provisions, and therefore do
not cover non-State actors such as Al Qaeda. The Administration further alleged that
the conflict with Al Qaeda is international in scope, and Common Article 3
accordingly was inapplicable to the conflict because it only covers armed conflicts
“not of an international nature.”6
The issue in Hamdan primarily concerned military tribunals convened by
Presidential order to try detainees for violations of the laws of war. The Court held
that such tribunals did not comply with the Uniform Code of Military Justice or the
laws of war, including the Geneva Conventions. However, the Court’s interpretation
of Common Article 3 had broader implications for U.S. policy towards captured Al
Qaeda suspects. The Court rejected the Administration’s interpretation of Common
Article 3 as not covering Al Qaeda members, concluding that the provision affords
“some minimal protection, falling short of full protection under the Conventions, to
[any] individuals ... who are involved in a conflict in the territory of a signatory.”7

In the aftermath of the Court’s ruling, the Department of Defense issued new
treatment guidelines concerning military detainees (including Al Qaeda members)
that required, at minimum, application of the standards articulated by Common
Article 3.8 Subsequently, fourteen high-level Al Qaeda operatives who had been held
abroad by the CIA and subjected to aggressive interrogation techniques were
transferred to DOD custody in Guantanamo Bay, Cuba.9
Scope of Prohibited Conduct under the War Crimes Act Relating to
Common Article 3 Violations. The United States has apparently never
prosecuted a person under the War Crimes Act.10 Perhaps as a result, there is some
question concerning the act’s scope. In the aftermath of the Court’s ruling in
Hamdan, some suggested that the War Crimes Act be amended to specify that certain
forms of treatment or interrogation violate the act. They argued that the scope of the
War Crimes Act was ambiguous, particularly as it related to offenses concerning
violations of Common Article 3. In a September 2006 address, President Bush
suggested that some provisions of Common Article 3 provided U.S. personnel with
inadequate notice as to what interrogation methods could permissibly be used against
detained Al Qaeda suspects, and requested legislation listing “specific, recognizable
offenses that would be considered crimes under the War Crimes Act.”11 On the other
hand, some argued that amending the War Crimes Act to cover specific acts would
overly restrict the act’s scope, making certain unspecified conduct legally permissible
even though it was as severe as conduct expressly prohibited by the act.
Although some types of conduct prohibited by Common Article 3 are easily
recognizable (e.g., murder, mutilation, the taking of hostages), it might not always
be obvious whether conduct constitutes impermissible “torture,” “cruel treatment,”

in Afghanistan, the Court noted that the official commentaries accompanying Common
Article 3 made clear that “the scope of the Article must be as wide as possible.” Id. (quoting
Commentary: Geneva Convention Relative to the Treatment of Prisoners of War 36 (1960)).
In dissent, Justice Thomas (joined by Justice Scalia) disputed this reading, arguing that the
relevant commentary indicated that the purpose of Common Article 3 was principally to
furnish protections to persons involved in a civil war, rather than entities of international
scope such as Al Qaeda. Id. at 2846 (Thomas, J., dissenting). However, the Court appeared
to leave unresolved whether the Geneva Conventions apply with respect to Al Qaeda
suspects captured in places where no armed conflict is occurring. For background on the

Liability under the War Crimes Act for U.S. Personnel on Account
of Pre-Hamdan Activities. Prior to the Court’s ruling in Hamdan, the Bush
Administration did not apply Common Article 3 protections to captured Al Qaeda
agents. In some cases, such persons were allegedly subject to harsh treatment,
especially in the context of interrogation, that might not have complied with
Common Article 3 requirements. As a result, some have raised questions as to
whether U.S. personnel might be criminally liable under the War Crimes Act for the
pre-Hamdan treatment of some Al Qaeda detainees.
Although not immune from prosecution, U.S. personnel who could be charged
with violating the War Crimes Act would have several possible defenses to criminal
liability, so long as their activities were conducted with the authorization of the
Administration and under the reasonable (though mistaken) belief that their actions
were lawful. Section 1004(a) of the Detainee Treatment Act of 2005 (DTA, P.L.
109-148), enacted several months prior to the Hamdan decision, provides that
In any civil action or criminal prosecution against an officer, employee, member
of the Armed Forces, or other agent of the United States Government who is a
United States person, arising out of the officer, employee, member of the Armed
Forces, or other agent’s engaging in specific operational practices, that involve
detention and interrogation of aliens who the President or his designees have
determined are believed to be engaged in or associated with international terrorist
activity that poses a serious, continuing threat to the United States ... and that
were officially authorized and determined to be lawful at the time that they were
conducted, it shall be a defense that ... [the] agent did not know that the practices
were unlawful and a person of ordinary sense and understanding would not know
the practices were unlawful. Good faith reliance on advice of counsel should be
an important factor, among others, to consider in assessing whether a person of
ordinary sense and understanding would have known the practices to be
unlawful. Nothing in this section shall be construed to limit or extinguish any
defense or protection otherwise available ... or to provide immunity from
prosecution for any criminal offense by the proper authorities.12
In addition to this statutory defense, a number of other legal defenses could be raised
by U.S. personnel charged with War Crimes Act offenses based on conduct that had
12 Prior to the enactment of the Military Commissions Act of 2006 (P.L. 109-366), it was
arguably unclear whether a reviewing court would have interpreted this defense to apply
retroactively to conduct occurring before the DTA’s enactment in December 2005. The
Military Commissions Act specified that this defense was available to U.S. persons charged
with an offense under the War Crimes Act on account of conduct committed between
September 11, 2001 and the enactment of the DTA. P.L. 109-366, § 8(b) (2006).

been authorized, assuming the defendants acted with government sanction and/or had
been erroneously informed by responsible authorities that their conduct was legal.13
Similar defenses may exist for military personnel in courts martial proceedings.14
Amendments made by the Military Commissions Act
In response to the Court’s ruling in Hamdan, Congress passed the Military
Commissions Act of 2006 (P.L. 109-366), which was enacted into law on October
17, 2006. Among other things, the Military Commissions Act (MCA) made several
amendments to the War Crimes Act.15
13 Although “mistake of law” defenses are generally rejected, such defenses have been
recognized by courts in certain cases where defendants have acted with government sanction
or after being erroneously informed by responsible authorities that their conduct was legal.
These defenses can be divided into three overlapping categories: (1) defense of entrapment
by estoppel
, available when a defendant is informed by a government official that certain
conduct is legal, and thereafter commits what would otherwise constitute a criminal offense
in reasonable reliance of this representation; (2) defense of public authority, available when
a defendant reasonably relies on the authority of a government official to authorize
otherwise illegal conduct, and the official has actual authority to sanction the defendant to
perform such conduct; and (3) defense of apparent public authority, which is recognized by
some (but not all) federal circuits, and is similar to the defense of public authority, except
that the official only needs to have apparent authority to sanction the defendant’s conduct.
United States v. Baptista-Rodriguez, 17 F.3d 1354, 1368 n. 18 (11th Cir. 1994). Unlike the
other defenses, the defense of entrapment by estoppel stems from the due process notions
of fairness, rather than from common law concerning contract, equity, or agency. United
States v. Austin, 915 F.2d 363, 366 (8th Cir. 1990).
14 While ignorance or mistake of law, including general orders or regulations, is not
generally available as a defense, “mistake of law may be a defense when the mistake results
from reliance on the decision or pronouncement of an authorized public official or agency.”
Manual for Courts Martial, Rules for Courts-Martial rule 916(l) (discussion). In the case
of war crimes, a defense based on superior orders is available only with respect to direct and
specific orders to commit an act constituting a war crime, and the defendant must
demonstrate both the existence of the order and his sincere and reasonable belief that the
order was lawful. See DAVID A. SCHLEUTER, MILITARY CRIMINAL JUSTICE § 2-4(F) (5th ed.
1999)(citing United States v. Huet-Vaughn, 43 M.J. 105 (1995)).
15 A number of bills were introduced in the 109th Congress in response to the Hamdan
decision, particularly as the decision related to the establishment of military tribunals to try
detainees for violations of the laws of war. Some of these bills contained provisions
amending the War Crimes Act to more fully protect U.S. personnel from criminal liability.
On September 6, 2006, the Bush Administration submitted draft legislation to Congress
authorizing military commissions to try detainees, amending the War Crimes Act, and
specifying conduct complying with Common Article 3. White House Press Release, Fact

The MCA amended the War Crimes Act provisions concerning Common
Article 3 so that only specified violations would be punishable (as opposed to any
Common Article 3 violation, as was previously the case), including committing, or
attempting or conspiring to commit
! torture (defined in a manner similar to that used by the Federal
Torture Statute, 18 U.S.C. §§ 2340-2340A, in criminalizing torture);
! cruel treatment;
! the performing of biological experiments;
! murder;
! mutilation or maiming;
! intentionally causing serious bodily injury;
! rape;
! sexual assault or abuse; and
! the taking of hostages.
Prior to the enactment of the MCA, there was some debate concerning the scope
of cruel treatment that should be subject to criminal penalty under the War Crimes
Act.16 The MCA defined “cruel treatment” prohibited by the War Crimes Act in a
similar manner to the definition of “torture” contained in the Federal Torture Statute.
However, whereas a person is criminally liable for torture only if he specifically
intends
to cause severe mental or physical pain and suffering, pursuant to the
amendments made the MCA, a person is criminally liable for inflictions of cruel

Tracking, Identification, and Prosecution Act of 2006, both introduced by Senator Bill Frist;
and H.R. 6054, the Military Commissions Act of 2006, introduced by Representative
Duncan Hunter. S. 3861, S. 3886, and H.R. 6054 were largely identical to the draft
legislation proposed by the Bush Administration, while S. 3901 somewhat differed. Soon
thereafter, three other bills were introduced: S. 3929 and S. 3930, which were both entitled
the Military Commissions Act of 2006 and were introduced by Senator Mitch McConnell;
and H.R. 6166, also entitled the Military Commissions Act of 2006, which was introduced
by Representative Duncan Hunter. Reportedly, S. 3929/S. 3930 and H.R. 6166 reflected an
agreement reached by the Bush Administration and certain lawmakers to resolve differences
in the approach taken by S. 3901 and that taken by S. 3861, S. 3886, and H.R. 6054. Kate
Zernike & Sheryl Gay Stolberg, Differences Settled in Deal Over Detainee Treatment, NY
TIMES, September 23, 2006, at A9. H.R. 6166 was passed by the House on September 27,
2006; S. 3930 was passed by the Senate on September 28, 2006 and by the House on
September 29, 2006. Although the provisions of S. 3929/S. 3930 and H.R. 6166 were
largely similar, there were initially some differences between the bills. However, the
version of S. 3930 that was passed by the Senate (S.Amdt. 5085) and House was amended
so that it contained the same provisions as House-passed H.R. 6166.
16 Several of the bills considered by the 109th Congress would have amended the War Crimes
Act to criminalize only some types of cruel treatment. For example, S. 3861, S. 3886, and
H.R. 6054 would only have criminalized cruel treatment rising to the level of torture, while
S. 3901 would have more broadly criminalized cruel treatment that violated the standards
of the McCain Amendment
(i.e., cruel, inhuman, or degrading treatment of the kind
prohibited under the Fifth, Eighth, and Fourteenth Amendments). The scope of conduct
criminalized by the MCA appears to fall somewhere between these two standards.

CRS-7
treatment if he generally intended17 to cause serious mental or physical pain and
suffering to a person protected under Common Article 3.
The MCA further defined “serious mental pain and suffering” and “serious
physical pain and suffering” rising to the level of cruel treatment punishable under
the War Crimes Act. “Serious mental pain and suffering” is defined by reference to
the Federal Torture Statute’s definition of “severe mental pain and suffering” rising
to the level of torture. Serious mental pain and suffering constituting cruel treatment
refers to pain and suffering arising from
! the intentional infliction or threatened infliction of severe physical
pain or suffering;
! the administration, application, or threatened administration or
application of mind-altering substances or other procedures
calculated to disrupt profoundly the senses or the personality;
! the threat of imminent death; or
! the threat that another person will imminently be subjected to death,
severe physical pain or suffering, or the administration or application
of mind-altering substances or other procedures calculated to disrupt
profoundly the senses or personality.
The type of mental pain and suffering constituting cruel treatment generally differs
from the type rising to the level of torture, in that it only needs to be of a serious and
non-transitory nature which need not be prolonged, as opposed to being of a severe
and prolonged nature. However, the War Crimes Act, as amended, provides that
with respect to conduct occurring before enactment of the MCA, such pain and
suffering must be of a prolonged nature.
As amended by the MCA, the War Crimes Act defines “serious physical pain
or suffering” constituting cruel treatment as actual bodily injury involving
! a substantial risk of death;
! extreme physical pain;
! a burn or physical disfigurement of a serious nature (other than cuts,
abrasions, or bruises); or
! significant loss or impairment of the function of a bodily member,
organ, or mental faculty.
Under U.S. jurisprudence, most or all of these activities are likely considered to be
of such severity as to constitute torture,18 at least in certain contexts, and could give
17 Specific intent is “the intent to accomplish the precise criminal act that one is later
charged with.” General intent usually “takes the form of recklessness (involving actual
awareness of a risk and the culpable taking of that risk) or negligence (involving
blameworthy inadvertence).” BLACK’S LAW DICTIONARY 813-814 (7th ed. 1999)

rise to criminal prosecution if the offender specifically intended to cause such injury.
However, such persons may now also be prosecuted under the War Crimes Act for
such conduct (presuming it was directed against persons protected under Common
Article 3), when they caused such injury through reckless or criminally negligent
action.19
The amendments made by the MCA to the War Crimes Act applied
retroactively, possibly precluding prosecution of personnel for some (but not all)
conduct falling under the more general scope of the earlier version of the War Crimes
Act.20 The MCA also provided that the statutory defense contained in DTA § 1004
covers any criminal prosecution under the War Crimes Act against U.S. personnel
relating to the sanctioned treatment of detainees, if such conduct occurred between
September 11, 2001, and December 30, 2005 (i.e., the date the DTA was enacted).21
It also amended the DTA to require the federal government to provide or employ
counsel and pay fees related to any prosecution or civil action against U.S. personnel
for authorized detention or interrogation activities.22 The MCA also specified that
certain provisions of the War Crimes Act, as amended, are inapplicable with respect
to collateral damage or a lawful attack.23 In addition, the provision of the War
Crimes Act, as amended, relating to hostage taking does not apply to prisoner
exchange during wartime. The MCA also prohibited U.S. courts from using foreign

In a 2002 memorandum interpreting the Federal Torture Statute, the Department of Justice
suggested that physical pain amounting to torture must be “equivalent in intensity to the pain
accompanying serious physical injury, such as organ failure, impairment of bodily function,
or even death.” Memorandum from the Office of Legal Counsel, Department of Justice, to

memorandum was superseded by another DOJ memo in 2004. The 2004 DOJ memorandum
rejected the earlier memo’s findings to the extent that it treated severe physical suffering as
identical to severe physical pain, and concluded that “severe physical suffering” may
constitute torture under the federal torture statute even if such suffering does not involve

Additionally, the MCA prevents persons from invoking the Geneva Conventions
as a source of rights in certain judicial proceedings. The Conventions are prohibited
from being invoked in habeas or civil proceedings to which the United States or a
current or former agent of the United States is a party.25
Post-MCA Developments Regarding
the Treatment of Detainees

The MCA authorizes the President, acting pursuant to an Executive Order
published in the Federal Register, to more restrictively interpret the meaning and
application of Common Article 3 of the Geneva Convention, and promulgate
administrative regulations implementing this interpretation,26 so long as these rules
do not authorize conduct subject to criminal penalty under the War Crimes Act.
On July 20, 2007, President Bush signed an Executive Order interpreting
Common Article 3, as applied to the detention and interrogation of certain alien
detainees by the CIA, when those aliens (1) are determined to be members or
supporters of Al Qaeda, the Taliban, or associated organizations; and (2) likely
possess information that could assist in detecting or deterring a terrorist attack
against the United States and its allies, or could provide help in locating senior
leadership within Al Qaeda or the Taliban.27 The Executive Order does not
specifically authorize the use of any particular interrogation techniques with respect
to detainees, but instead bars any CIA detention and interrogation program from
employing certain practices. Specifically, the Order prohibits the use of
! torture, as defined under the Federal Torture Statute (18 U.S.C. §
2340);
! cruel, inhuman, and degrading treatment, as defined under the
McCain Amendment and the MCA;
! any activities subject to criminal penalties under the War Crimes Act
(e.g., murder, rape, mutilation);
! other acts of violence serious enough to be considered comparable
to the kind expressly prohibited under the War Crimes Act;
24 Id., § 6(a)(2).
25 Id., § 5(a). The Military Commission Act also revoked U.S. courts’ jurisdiction to hear
habeas corpus petitions by aliens in U.S. custody as enemy combatants. Id., § 7. The
constitutionality of the MCA’s provisions limiting habeas jurisdiction and prohibiting the
Geneva Conventions from being invoked as a source of rights in judicial proceedings has
been subject to legal challenge. For background and development of recent litigation, see

! acts intended to denigrate the religion, religious practices, or
religious objects of the individual.
The scope of activity prohibited by the Order is not immediately apparent.
Although some types of conduct barred by the Order are easily recognizable (e.g.,
murder, rape, the performance of sexual acts), it is not readily apparent as to what
interrogation techniques would fall under the Order’s prohibition against acts deemed
to be “cruel, inhuman, and degrading” or “beyond the bounds of human decency.”
Certain interrogation techniques that have been the subject of controversy —
waterboarding, hooding, sleep deprivation, or forced standing for prolonged periods,
for example — are not specifically addressed by the Order. Whether or not such
conduct is deemed by the Executive to be barred under the more general restrictions
of the Order, such as the restriction on treatment comparable to the kind expressly
prohibited by the War Crimes Act, remains unclear.
