Arrest and Detention of Material Witnesses: Federal
Law In Brief and Section 12 of the USA PATRIOT and
Terrorism Prevention Reauthorization Act (H.R. 3199)
Summary
Witnesses at Congressional oversight hearings alleged that the authority to arrest
and hold material witnesses until their appearance at federal criminal proceedings
(including grand jury proceedings) had been abused following September 11, 2001.
Section 12 of the USA PATRIOT Act and Terrorism Prevention Reauthorization Act
(H.R. 3199) as reported by the House Judiciary Committee called for a periodic
review and reports on the use of the material witness statute. In the face of
Administration opposition, however, the provision was dropped from the bill prior
to House consideration. No similar proposal can be found in the version of H.R.
3199 (S. 1389) approved in the Senate. The episode illustrates the level of
controversy easily generated by material witness statutes.
This is an overview of the law under the federal material witness statute which
authorizes the arrest of material witnesses, permits their release under essentially the
same bail laws that apply to federal criminal defendants, but favors their release after
their depositions have taken.
A list of citations to comparable state statutes and a bibliography of law review
articles and notes are appended.

Arrest and Detention of Material Witnesses:
Federal Law in Brief and Section 12 of the
USA PATRIOT and Terrorism Prevention
Reauthorization Act (H.R. 3199)
Introduction
When reported by the House Committee on the Judiciary, section 12 of the USA
PATRIOT and Terrorism Prevention Reauthorization Act (H.R. 3199) directed the
Department of Justice to review the detention of individuals under the federal
material witness statute, “including their length [of detention], conditions of access
to counsel, frequency of access to counsel, offense at issue, and frequency of
appearance before a grand jury.” The Office of Management and Budget announced
that the Administration strongly opposed section 12 on the grounds that the review
by the Department of Justice’s Inspector General and reports to the House and Senate
Judiciary Committees called for by that section would “entail wholesale violation”of
the grand jury secrecy provisions.1 Perhaps as a consequence, the section was
dropped from the bill prior to House consideration and no comparable provision
appears in the version of H.R. 3199 which the Senate approved.
The episode illustrates the level of controversy easily generated by material
witness statutes. Under the federal statute, 18 U.S.C. 3144, witnesses in a federal
criminal case may find themselves arrested, held for bail, and in some cases
imprisoned until they are called upon to testify. The same is true in most if not all
of the states.2 Although subject to intermittent criticism,3 it has been so at least from

denied that the federal material witness statute can be used as a substitute for a
criminal arrest warrant.8 Particularly in the early stages of an investigation, however,
an individual’s proximity to a crime may make him both a legitimate witness and a
legitimate suspect.9
The case law and statistical information suggest that the federal statute is used
with surprising regularity10 and most often in the prosecution of immigration offenses
involving material witnesses who are foreign nationals.11 Critics, however, contend

arrested and detained in abuse of the statute’s authority.12
Arrest
The federal material witness statute provides that:
If it appears from an affidavit filed by a party that the testimony of a person is
material in a criminal proceeding, and if it is shown that it may become
impracticable to secure the presence of the person by subpoena, a judicial officer
may order the arrest of the person and treat the person in accordance with the
provisions of section 3142 of this title [relating to bail]. No material witness may
be detained because of inability to comply with any condition of release if the
testimony of such witness can adequately be secured by deposition, and if further
detention is not necessary to prevent a failure of justice. Release of a material
witness may be delayed for a reasonable period of time until the deposition of the
witness can be taken pursuant to the Federal Rules of Criminal Procedure. 18
U.S.C. 3144.
An arrest warrant for a witness with evidence material to a federal criminal
proceeding may be issued by federal or state judges or magistrates.13 The statute

13 18 U.S.C. 3156(a)(1)(“As used in sections 3141-3150 of this chapter– (1) the term
‘judicial officer’ means, unless otherwise indicated, any person or court authorized pursuant
to section 3041 of this title, or the Federal Rules of Criminal Procedure, to detain or release

applies to potential grand jury witnesses as well as to potential trial witnesses.14
Section 3144 on its face authorizes arrest at the behest of any party to a criminal
proceeding. In the case of criminal trial, both the government and the defendants
may call upon the benefits of section 3144.15 Availability is a bit less clear in the
case of grand jury proceedings. In a literal sense, there are no parties to a grand jury
investigation other than the grand jury.16 Moreover, it seems unlikely that a suspect,
even the target of a grand jury investigation, would be considered a “party” to a grand
jury proceeding. The purpose of section 3144 is the preservation of evidence for
criminal proceedings. Potential defendants, even if they are the targets of a grand
jury investigation, have no right to present evidence to the grand jury.17 On the other
hand, a federal prosecutor ordinarily arranges for the presentation of witnesses to the
grand jury.18 It is therefore not surprising that the courts seem to assume without
deciding that the government may claim the benefits of section 3144 in the case of
grand jury witnesses.19
Issuance of a section 3144 arrest warrant requires affidavits establishing
probable cause to believe (1) that the witness can provide material evidence, and (2)
that it will be “impracticable” to secure the witness’ attendance at the proceeding
simply by subpoenaing him.20 Neither the statute nor the case law directly address
a person before trial or sentencing or pending appeal in a court of the United States, and any
judge of the Superior Court of the District of Columbia”). Section 3041 authorizes federal
and state judges and magistrates to issue arrest warrants and conduct bail proceedings in
federal criminal cases.

function is that it belongs to no branch of the institutional government”).

not have a right to testify or have exculpatory evidence presented”).
18 Rule 17(a) of the Federal Rules of Criminal Procedure states that federal criminal
subpoenas are issued in blank by the clerk of the court and filled in by “the party” requesting
them. Nevertheless, federal prosecutors complete and see to the service of most grand jury
subpoenas, Lopez v. United States, 393 F.3d 1345, 1349 (D.C.Cir. 2005)(“the term ‘grand
jury subpoena’ is in some respects a misnomer, because the grand jury itself does not decide
whether to issue the subpoena; the prosecuting attorney does”).
19 See e.g., United States v. Awadallah, 349 F.3d 42, 66 (2d Cir. 2003)(“in the case of a
grand jury proceeding, we think that a statement by a responsible official, such as the United

the question of what constitutes “material” evidence for purposes of section 3144, but
in other contexts the term is understood to mean that which has a “natural tendency
to influence, or is capable of influencing, the decision of the decisionmaking body
to which it was addressed.”21 At the grand jury level, the government may establish
probable cause to believe a witness can provide material evidence through the
affidavit of a federal prosecutor or a federal investigator gathering evidence with an
eye to its presentation to the grand jury.22 This may not prove a particularly
demanding standard in some instances given the sweeping nature of the grand jury’s
power of inquiry.23
As to the second required probable cause showing, a party seeking a material
witness arrest warrant must establish probable cause to believe that it will be
impractical to rely upon a subpoena to securing the witness’ appearance. The case
law on point is sketchy, but it seems to indicate that impracticality may be shown by
evidence of possible flight,24 or of an expressed refusal to cooperate,25 or of difficulty

506, 509 (1995)(materiality as an element of various federal fraud statutes). In the context
of the prosecution’s failure to disclose material exculpatory evidence, “the material standard
Brady claims is met when the favorable evidence could reasonably be taken to put the whole
case in such a different light as to undermine confidence in the verdict,” Banks v. Dretke,
540 U.S. 668, 698 (2004), quoting, Kyles v. Whitley, 514 U.S. 419, 435 (1995).

23 Branzburg v. Hayes, 408 U.S. 665, 688 (1972)(“Because [the grand jury’s] task is to
inquire into the existence of possible criminal conduct and to return only well-founded
indictments, its investigative powers are necessarily broad. It is a grand inquest, a body with
powers of investigation and inquisition, the scope of whose inquiries is not to be limited
narrowly by questions of propriety or forecasts of the probable result of the investigation,
or by doubts whether any particular individual will be found properly subject to an
accusation of crime”); United States v. R. Enterprises, Inc., 498 U.S. 292, 297 (1991)(“The
function of the grand jury is to inquire into all information that might possibly bear on its
investigation until it has identified an offense or has satisfied itself that none has occurred.
As a necessary consequence of its investigatory function, the grand jury paints with a broad
brush. A grand jury investigation is not fully carried out until every available clue has been
run down and all witnesses examined in every proper way to find if a crime has been
committed”).
24 The government’s affidavit merely asserted “with respect to the probability of Nichol’s
flight: Terry Nichols’ renunciation of his U.S. citizenship and his association with Tim
McVeigh, a person involved in such a heinous crime, indicates that his testimony cannot be
secured through the issuance of a subpoena,” In re Material Witness Warrant, 77 F.3d 1277,
1278 (10th Cir. 1996), dismissing as moot an appeal from, United States v. McVeigh, 940
F.Supp. 1541, 1562 (D.Colo. 1996)(denial of a motion to quash a material witness arrest
warrant on grounds of impracticality).
25 United States v. Coldwell, 496 F.Supp. 305, 307 (E.D. Okla. 1979)(As to impracticality,
“the Dempewolf affidavit shows that (a) Alston has refused to cooperate with law
enforcement officials. . . (b) Alston has indicated that he will not testify in this case unless
the Oklahoma Bureau . . . satisfies certain conditions that . . . are impossible to meet; (c) two
unsuccessful attempts have been made to serve Alston with a subpoena through his attorney;

experienced in serving a subpoena upon a trial witness,26 or presumably by evidence
that the witness is a foreign national who will have returned or been returned home
by the time his testimony is required.27 Evidence that investigators have experienced
difficulties serving a particular grand jury witness may not be enough to justify the
issuance of an arrest warrant in all cases.28
Bail
With limited variations, federal bail laws apply to material witnesses arrested
under section 3144.29 Arrested material witnesses are entitled to the assistance of
counsel during bail proceedings and to the appointment of an attorney when they are
unable to detain private counsel.30 The bail laws operate under an escalating system
in which release is generally favored, then release with conditions or limitations is
and (d) Alston’s attorney has indicated that Alston has expressed a definite unwillingness
to cooperate with the government”).
26 United States v. Feingold, 416 F.Supp. 627, 628 (E.D.N.Y. 1976)(“We are not here
dealing with a witness before a grand jury where disregard of a subpoena would simply
mean a continuation of the grand jury’s deliberations until an appropriate warrant might be
served and executed. Here, Feingold’s testimony is needed at Nashi’s trial. Once
commenced, the trial would continue on consecutive days, and Feingold’s testimony would
be needed before the Government rested its case. Since Feingold is presumably in
California, for the Government to have to defer its arrest warrant until he ignored a
subpoena to attend the trial will preclude his testifying altogether. The . . . affidavit showed
unsuccessful attempts to serve Feingold with a subpoena either through his California
attorney or on seven different days at Feingold’s home”).
27 Perhaps because the point seems too obvious for dispute or discussion, none of the
reported federal cases appear to have held the impracticality of future appear requirement
can be satisfied by evidence that a material witness, who is a foreign national illegally
present in this country, may be overseas and thus beyond the reach of the court’s subpoena
when his testimony is required. The number of foreign material witnesses arrested and held
for the trial of immigration prosecutions indicate the government has experienced little
difficulty satisfying the impracticality requirement in such cases, see e.g., Torres-Ruiz v.

preferred, and finally as a last option detention is permitted.31 A defendant is released
on his word (personal recognizance) or bond unless the court finds such assurances
insufficient to guarantee his subsequent appearance or to ensure public or individual
safety.32 A material witness need only satisfy the appearance standard.33 A material
witness who is unable to do so is released under such conditions or limitations as the
court finds adequate to ensure his later appearance to testify.34 If neither word nor
bond nor conditions will suffice, the witness may be detained.35 The factors a court
may consider in determining whether a material witness is likely to remain available
include his deposition, character, health, and community ties.36
Depositions
Section 3144 declares that “[n]o material witness may be detained because of
inability to comply with any condition of release if the testimony of such witness can
adequately be secured by deposition, and if further detention is not necessary to
prevent a failure of justice.” The corresponding federal deposition rule permits the
witness,37 the government, or the defendant to request that a detained material
witness’ deposition be taken.38 A court enjoys only limited discretion to deny a

with an offense, the judicial officer shall issue an order that, pending trial, the person be –

under subsection (b) of this section; (2) released on a condition or combination of conditions
under subsection (c) of this section; (3) temporarily detained to permit revocation of
conditional release, deportation, or exclusion under subsection (d) of this section; or (4)
detained under subsection (e) of this section.”).

personal recognizance, or upon execution of an unsecured appearance bond in an amount
specified by the court, subject to the condition that the person not commit a Federal, State,

release will not reasonably assure the appearance of the person as required or will endanger
the safety of any other person or the community”).

detained witness’ request. The Fifth Circuit has observed that, “Read together, Rule
15(a) and section 3144 provide a detained witness with a mechanism for securing his
own release. He must file a written motion requesting that he be deposed. The
motion must demonstrate that his testimony can adequately be secured by deposition,
and that further detention is not necessary to prevent a failure of justice. Upon such
showing, the district court must order his deposition and prompt release,” Aguilar-
Ayala v. Ruiz
, 973 F.2d 411, 413 (5th Cir. 1992). Other courts seem to agree.39 The
“failure of justice” limitation comes into play when release of the witness following
the taking of his deposition would ultimately deny a defendant the benefit of
favorable material testimony in derogation of his right to compulsory process.40 It
does not include the fact that a judicial officer will not be present at the taking of the
deposition or that the witness is an illegal alien subject to prosecution.41
Unlike the request of a detained witness, a government or defendant’s request
that a witness’ deposition be taken must show “exceptional circumstances” and that
granting the request is “in the interest of justice,” F.R.Crim.P. 15(a)(1).42
Nevertheless, the fact that a witness is being detained will often be weighed heavily
regardless of who requests that depositions be taken.43 The Circuits appear to be
divided over whether in compliance with a local standing order the court may
authorize depositions to be taken sua sponte in order to release a detained material
not privileged, including any book, paper, document, record, recording, or data.”).

The government must periodically report to the court on the continuing
justification for holding an incarcerated material witness.46 While a material witness
is being held in custody he is entitled to the daily witness fees authorized for
attendance at judicial proceedings.47 Upon his release, the court may also order that
he be provided with transportation and subsistence to enable him to return to his

Section 12
Witnesses at Congressional oversight hearings charged that the authority under
18 U.S.C. 3144 had been misused following September 11, 2001:
[The authority has been used] to secure the indefinite incarceration of those
[prosecutors] wanted to investigate as possible terrorist suspects. This allowed
the government to . . . avoid the constitutional protections guaranteed to suspects,
including probable cause to believe the individual committed a crime and time-
limited detention. . .
Witnesses were typically held round the clock in solitary confinement, subjected
to the harsh and degrading high security conditions typically reserved for the
most dangerous inmates accused or convicted of the most serious crimes. . . they
were interrogated without counsel about their own alleged wrongdoing.
. . . [A] large number of witnesses were never brought before a grand jury or
court to testify. More tellingly, in repeated cases the government has now
apologized for arresting and incarcerating the “wrong guy.” The material
witnesses were victims of the federal investigators and attorneys who were to[o]
quick to jump to the wrong conclusions, relying on false, unreliable and
irrelevant information. By evading the probable cause requirement for arrests of
suspects, the government made numerous mistakes.51
At the same hearings the Justice Department pointed out that the material
witness statute is a long-standing and generally applicable law and not a creation of
the USA PATRIOT Act; that it operates under the supervision of the courts; that
witnesses are afforded the assistance of counsel (appointed where necessary); and
that witnesses are ordinarily released following their testimony.52

Section 12 of H.R. 3199 as reported by the House Committee on the Judiciary
amended section 1001 of the USA PATRIOT Act by directing periodic review of the
exercise of the authority under section 3144. In its original form section 1001
instructs the Justice Department Inspector General to designate an official who is (1)
to receive and review complaints of alleged Justice Department civil rights and civil
liberties violations, (2) to widely advertise his availability to receive such complaints,
and (3) to report to the House and Senate Judiciary Committees twice a year on
implementation of that requirement, P.L. 107-56, 115 Stat. 381 (2001). Section 12
amended section 1001 to impose additional responsibilities upon the Inspector
General’s designee , i.e., (1) to “review detentions of persons under section 3144 of
title 18, United States Code, including their length, conditions of access to counsel,
frequency of access to counsel, offense at issue, and frequency of appearances before
a grand jury,” (2) to advertise his availability to receive information concerning such
activity, and (3) to report twice a year on implementation to the Judiciary Committees
on implementation of this requirement.
OMB announced that the Administration generally supports H.R. 3199 as
passed by the House, but that “[t]he Administration strongly oppose[d] section 12 of
H.R. 3199, which would authorize the Department of Justice’s Inspector General to
investigate the use of material witnesses. As it is written, this provision would entail
wholesale violation of Rule 6(e) of the Federal Rules of Criminal Procedure, which
protects the secrecy and sanctity of grand jury proceedings.”53
The exact nature of OMB’s objection is somewhat unclear. Rule 6(e) prohibits
disclosure of matters occurring before the grand jury, F.R.Crim.P. 6(e). Its purpose
is to: (1) prevent the flight of suspects, (2) avoid defaming suspects ultimately found
blameless, (3) shield the grand jury from the corrupt influences of the targets of its
investigations, and (4) encourage witnesses to be forthcoming.54 The rule does not
prohibit disclosure by grand jury witnesses of matters occurring during their
appearance before the panel.55 There is some authority for the proposition that the
rule does not bar disclosure to Congress.56 And there is reason to believe that the rule

does not apply to executive branch officials with supervisory authority over Justice
Department attorneys who assist the grand jury.57 In addition, from time to time,
Congress has created several other exceptions to the rule’s general prohibitions either
by amendment of the Rule,58 or by a provision elsewhere in the Code.59
The OMB statement that “[a]s it is written, this provision would entail
wholesale violation of Rule 6(e) of the Federal Rules of Criminal Procedure” may be
an objection to the fact that the proposal does not take the form of an amendment to
Rule 6(e).60 Yet it seems unlikely that OMB would base a statement of “strong”
opposition solely on a question of legislative drafting style.
The statement could be read as a claim that Congress lacks the legislative
authority to enact a provision at odds with Rule 6(e). But this cannot be. The rules
were and are promulgated as an exercise of legislative authority.61 Even when
amendments to the Federal Rules of Criminal Procedure come from the courts they
are subject to Congressional rejection or modification before they become effective.62
The statement might be understood to declare that compliance with section 12
would involve “wholesale” disclosures which would be contrary to the purpose and
demands of Rule 6(e) were it not superseded by the instructions of section 12. This
might be seen as a contention that without the intervention of section 12, Rule 6(e)
would prohibit disclosure of the information identified in section 12 to the designee
of the Justice Department’s Inspector General, or to the House and Senate Judiciary
Committees, or to either of them.
This may be something of an overstatement. First, Rule 6(e) is implicated only
with regard to matters occurring before the grand jury. Thus, Rule 6(e) is not
implicated with respect to information concerning the detention of material trial
witnesses under section 3144 of title 18. Nor is it clear that Rule 6(e) would be
implicated by disclosure of information concerning the length of confinement or

58 E.g., section 203(a) of USA PATRIOT Act, 115 Stat. 279 (2001)(amending Rule 6(e)
to permit foreign intelligence information sharing with various federal officials, see
F.R.Crim.P. 6(e)(3)(D)).

access to counsel of material grand jury witnesses as long as individual witnesses
were not identified; nor of information in the aggregate of the offenses at issue and
frequency of grand jury appearances of incarcerated material witnesses.63 But for
section 12, Rule 6(e) would seem to apply to the identities of incarcerated grand jury
witnesses, the offenses under consideration by specific grand jury panels, and the
frequency of appearance by specific incarcerated witnesses. Even here, however, it
is far from clear that absent section 12 the Rule would preclude disclosure to
Congress or to Justice Department officials whose duties include investigation of
misconduct by Department attorneys.64
Nevertheless, perhaps because of Administration opposition, the provision was
dropped from H.R. 3199 prior to House passage and no similar provision can be
found in H.R. 3199 (S. 1389) as approved in the Senate.
