Comparison of Military Commission Trials and Trials in Federal Criminal Court

Summary
Attorney General Holder’s decision to try certain detainees in federal criminal court, including
those accused of conspiring to commit the 9/11 terrorist attacks, and to try other detainees by
military commission, has focused attention on the procedural differences between trials in federal
court and those conducted under the Military Commissions Act, as recently amended. Some who
are opposed to the decision argue that bringing detainees to the United States for trial poses a
security threat and risks disclosing classified information, or could result in the acquittal of
persons who are guilty. Others have praised the decision as recognizing the efficacy and fairness
of the federal court system and have voiced confidence in the courts’ ability to protect national
security while achieving justice that will be perceived as such among U.S. allies abroad. Some
continue to object to the planned trials of detainees by military commission, despite the
amendments Congress enacted as Title XVIII of the National Defense Authorization Act for
Fiscal Year 2010, P.L. 111-84, because they say it demonstrates a less than full commitment to
justice or that it casts doubt on the strength of the government’s case against those detainees.
This report provides a brief summary of legal issues raised by the choice of forum for trying
accused terrorists and a table comparing selected military commissions rules under the Military
Commissions Act, as amended, to the corresponding rules that apply in federal court. The table

Comparison of Military Commission Trials and Trials in Federal Criminal Court

Introduction
Attorney General Holder’s decision to try certain detainees in federal criminal court, including
those accused of conspiring to commit the 9/11 terrorist attacks, and to try other detainees by
military commission, has focused attention on the procedural differences between trials in federal
court and those conducted under the Military Commissions Act, as amended. Some who are
opposed to the decision argue that bringing detainees to the United States for trial poses a security
threat and risks disclosing classified information, or could result in the acquittal of persons who
are guilty. Others have praised the decision as recognizing the efficacy and fairness of the federal
court system and have voiced confidence in the courts’ ability to protect national security while
achieving justice that will be perceived as such, particularly among U.S. allies abroad. Some
continue to object to the planned trials of detainees by military commission, despite the
amendments Congress enacted as Title XVIII of the National Defense Authorization Act for
Fiscal Year 2010 (Military Commissions Act of 2009), P.L. 111-84, because they say it
demonstrates a less than full commitment to justice or that it casts doubt on the strength of the
government’s case against those detainees.
This report provides a brief summary of legal issues raised by the choice of forum for trying
accused terrorists and a table comparing authorities and composition of the federal courts to those
of military commissions. A second table compares selected military commissions rules under the
Military Commissions Act, as amended by the Military Commissions Act of 2009, to the

Background
On January 22, 2009, President Barack Obama issued an Executive Order requiring that the
Guantanamo detention facility, which continues to house more than 200 aliens detained in
connection with post-9/11 military operations, be closed no later than a year from the date of the
Order.1 The Order establishes a task force to review all Guantanamo detentions to assess whether
each detainee should continue to be held by the United States, be transferred or released to
another country, or be prosecuted by the United States for criminal offenses. Ongoing military
commissions have been essentially halted during this review period, although some pretrial

Closure of Detention Facilities,” 74 Federal Register 4897, January 22, 2009 [hereinafter “Executive Order”].

proceedings have continued to take place. One detainee, Ahmed Ghailani, was transferred in June
to the Southern District of New York for trial in federal court on charges related to his alleged
role in the 1998 East Africa Embassy bombings.
President Obama’s Detention Policy Task Force2 issued a preliminary report July 20, 2009,
reaffirming that the White House considers military commissions to be an appropriate forum for
trying some cases involving suspected violations of the laws of the war, although federal criminal
court would be the preferred forum for any trials of detainees.3 The disposition of each case
referred for criminal prosecution is to be assigned to a team comprised of DOJ and DOD
personnel, including prosecutors from the Office of Military Commissions. The report also
provided a set of criteria to govern the disposition of cases involving Guantanamo detainees. In
addition to “traditional principles of federal prosecution,” the protocol identifies three broad
categories of factors to be taken into consideration:
• Strength of interest, namely, the nature and gravity of offenses or underlying
conduct; identity of victims; location of offense; location and context in which
individual was apprehended; and the conduct of the investigation.
• Efficiency, namely, protection of intelligence source and methods; venue; number
of defendants; foreign policy concerns; legal or evidentiary problems; efficiency
and resource concerns.
• Other prosecution considerations, namely, the extent to which the forum and
offenses that can be tried there permit a full presentation of the wrongful conduct,
and the available sentence upon conviction.
On November 13, 2009, Attorney General Holder announced his decision to transfer the five
“9/11 conspirators,” who include Khalid Sheikh Mohammed, Walid Muhammed Salih Mubarak
Bin Attash, Ramzi Bin Al Shibh, Ali Abdul-Aziz Ali, and Mustafa Ahmed Al Hawsawi, to the
Southern District of New York to stand trial.4 Five other detainees are to be tried by military
commission. These include Omar Khadr, a Canadian citizen captured as a teenager and charged
before a military commission for allegedly throwing a hand grenade that killed a U.S. medic in
Afghanistan; Abd al-Rahim al-Nashiri, whose military commission charges related to the October
2000 attack on the USS Cole were previously withdrawn in February; Ahmed Mohammed
Ahmed Haza al Darbi, who is accused of participating in an al-Qaeda plot to blow up oil tankers
in the Straits of Hormuz, and two other detainees about whom no further information was given.
Forum Choice for Terror Suspects
U.S. law provides for the trial of suspected terrorists, including those captured abroad, in several
ways. Those who are accused of violating specific federal laws are triable in federal criminal
court. Provisions in the U.S. Criminal Code relating to war crimes and terrorist activity apply

extraterritorially and may be applicable to some detainees.5 Those accused of violating the law of
war or committing the offenses enumerated in the Military Commissions Act (MCA), as amended
by the Military Commissions Act of 2009,6 may be tried by military commissions under the
MCA, or by general court-martial under the UCMJ.7
The procedural protections afforded to the accused in each of these forums may differ. The MCA
authorizes the establishment of military commissions with jurisdiction to try alien “unprivileged
enemy belligerents”8 for offenses made punishable by the MCA or the law of war.
Notwithstanding the recent amendments to the MCA, which generally enhance due process
guarantees for the accused, critics continue to question their constitutionality.
One issue that has been raised by proponents of the use of military commissions is the concern
that federal criminal courts would endow accused terrorists with constitutional rights they would
not otherwise enjoy. The MCA does not restrict military commissions from exercising jurisdiction
within the United States, and the Supreme Court has previously upheld the use of military
commissions against “enemy belligerents” tried in the United States under procedural rules that
differed from the federal rules.9 The Supreme Court has not settled the question regarding the
extent to which constitutional guarantees apply to aliens detained at Guantanamo, making any
difference in rights due to location of the trials difficult to predict. Some view the unpredictability
of the Supreme Court’s acceptance of the military commission procedures as a factor in favor of
using civilian trial courts.
Sources of Rights
The Fifth Amendment to the Constitution provides that “no person shall be ... deprived of life,
liberty, or property, without due process of law.” Due process includes the opportunity to be heard
whenever the government places any of these fundamental liberties at stake. The Constitution
contains other explicit rights applicable to various stages of a criminal prosecution. Criminal
proceedings provide both the opportunity to contest guilt and to challenge the government’s
conduct that may have violated the rights of the accused. The system of procedural rules used to
conduct a criminal hearing, therefore, serves as a safeguard against violations of constitutional
rights that take place outside the courtroom, for example, during arrests and interrogations.
The Bill of Rights applies to all citizens of the United States and all aliens within the United
States.10 However, the methods of application of constitutional rights, in particular the remedies

6 Title XVIII of the National Defense Authorization Act for Fiscal Year 2010, P.L. 111-84.
7 See 10 U.S.C. § 818 (jurisdiction of general court-martial over any person triable under the law of war). The
jurisdiction of common law military commissions under the UCMJ is also preserved to try “offenders or offenses that
by statute or by the law of war may be tried by military commissions, provost courts, or other military tribunals.” 10
U.S.C. § 821. No proposals have been floated to use general courts-martial or military commissions under the UCMJ to
try Guantanamo detainees. This report will discuss federal court trials and trials under the Military Commissions Act of
2009.

available to those whose rights might have been violated, may differ depending on the severity of
the punitive measure the government seeks to take and the entity deciding the case. The
jurisdiction of various entities to try a person accused of a crime could have a profound effect on
the procedural rights of the accused. The type of judicial review available also varies and may be
crucial to the outcome.
International law also contains some basic guarantees of human rights, including rights of
criminal defendants and prisoners. Treaties to which the United States is a party are expressly
made a part of the law of the land by the Supremacy Clause of the Constitution11 and may be
codified through implementing legislation,12 or in some instances, may be directly enforceable by
the judiciary.13 International law is incorporated into U.S. law,14 but does not take precedence
over statute. The law of war, a subset of international law, applies to cases arising from armed
conflicts (i.e., war crimes).15 It remains unclear how the law of war applies to the current
hostilities involving non-state terrorists, and the nature of the rights due to accused terrorist/war
criminals may depend in part on their status under the Geneva Conventions. The Supreme Court
has ruled that Al Qaeda fighters are entitled at least to the baseline protections applicable under
Common Article 3 of the Geneva Conventions,16 which includes protection from 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.”17
Federal Court
The federal judiciary is established by Article III of the Constitution and consists of the Supreme
Court and “inferior tribunals” established by Congress.18 It is a separate and co-equal branch of
the federal government, independent of the executive and legislative branches, designed to be
insulated from the public passions. Its function is not to make law, but rather to interpret law and
decide disputes arising under it. Federal criminal law and procedures are enacted by Congress and
codified primarily in title 18 of the U.S. Code. The Supreme Court promulgates procedural rules

inapplicable to the conflict with Al Qaeda and interpreted the phrase “in contradistinction to a conflict between
nations,” which the Geneva Conventions designate a “conflict of international character.”

for criminal trials at the federal district courts, subject to Congress’s approval. These rules,
namely the Federal Rules of Criminal Procedure (Fed. R. Crim. P.) and the Federal Rules of
Evidence (Fed. R. Evid.), incorporate procedural rights that the Constitution and various statutes
demand. The tables provided at the end of this report cite relevant rules or court decisions, but
make no effort to provide an exhaustive list of authorities.
Military Commissions
The Constitution empowers Congress to declare war and “make rules concerning captures on land
and water,”19 to define and punish violations of the “Law of Nations,”20 and to make regulations
to govern the armed forces.21 The power of the President to convene military commissions flows
from his authority as Commander in Chief of the Armed Forces22 and his responsibility to execute
the laws of the nation.23 Under the Articles of War and subsequent statute,24 the President has at
least implicit authority to convene military commissions to try offenses against the law of war.25
The authority and objectives underlying military courts-martial and military commissions are not
coextensive.26 Rather than serving the internally directed purpose of maintaining discipline and
order of the troops, the military commission is externally directed at the enemy as a means of
waging successful war by punishing and deterring offenses against the law of war. Military
commissions have historically been used in connection with military government in cases of
occupation or martial law where ordinary civil government was impaired.
Jurisdiction of military commissions is limited to time of war and to trying offenses recognized
under the law of war or as designated by statute.27 While case law suggests that military
commissions could try U.S. citizens as enemy belligerents,28 the Military Commissions Act
permits only aliens to be tried. The United States first used military commissions to try enemy
belligerents accused of war crimes during the occupation in Mexico in 1847, and made heavy use
of them in the Civil War and in the Philippine Insurrection.29 However, prior to President Bush’s
Military Order of 2001 establishing military commissions for certain alien terrorism suspects, no
military commissions had been convened since the aftermath of World War II. As non-Article III

24 The Articles of War were re-enacted at 10 U.S.C. § 801 et seq. as part of the UCMJ. Although there is no case law
interpreting the UCMJ as authorizing military commissions, the relevant sections of the UCMJ, which recognize the
concurrent jurisdiction of military commissions to deal with “offenders or offenses designated by statute or the law of
war,” are essentially identical to the corresponding language in the Articles of War. See 10 U.S.C. § 821.

Defense to establish regulations for military commissions in accordance with its provisions.
