(February 23, 2012)
Before TJOFLAT, MARTIN and HILL, Circuit Judges.

TJOFLAT, Circuit Judge:

This is an appeal of a judgment of civil contempt. On April 7, 2011, John

Doe was served with a subpoena duces tecum requiring him to appear before a

Northern District of Florida grand jury and produce the unencrypted contents

located on the hard drives of Doe’s laptop computers and five external hard

drives.1 Doe informed the United States Attorney for the Northern District of

Florida that, when he appeared before the grand jury, he would invoke his Fifth

Amendment privilege against self-incrimination and refuse to comply with the

subpoena.2 Because the Government considered Doe’s compliance with the

subpoena necessary to the public interest, the Attorney General, exercising his

1
The contents of the drives were encrypted. The subpoena required Doe to decrypt and
produce the contents.

The Fifth Amendment to the United States Constitution reads:

No person shall be held to answer for a capital, or otherwise infamous crime,
unless on a presentment or indictment of a Grand Jury, except in cases arising in
the land or naval forces, or in the Militia, when in actual service in time of War or
public danger; nor shall any person be subject for the same offence to be twice put
in jeopardy of life or limb; nor shall be compelled in any criminal case to be a
witness against himself, nor be deprived of life, liberty, or property, without due
process of law; nor shall private property be taken for public use, without just
compensation.

U.S. Const. amend. V.

authority under 18 U.S.C. § 6003,3 authorized the U.S. Attorney to apply to the

district court, pursuant to 18 U.S.C. §§ 60024 and 6003, for an order that would

grant Doe immunity and require him to respond to the subpoena.

3
18 U.S.C. § 6003 reads:

(a) In the case of any individual who has been or may be called to testify or
provide other information at any proceeding before or ancillary to a court of the
United States or a grand jury of the United States, the United States district court
for the judicial district in which the proceeding is or may be held shall issue, in
accordance with subsection (b) of this section, upon the request of the United
States attorney for such district, an order requiring such individual to give
testimony or provide other information which he refuses to give or provide on the
basis of his privilege against self-incrimination, such order to become effective as
provided in section 6002 of this title.

(b) A United States attorney may, with the approval of the Attorney General, the
Deputy Attorney General, the Associate Attorney General, or any designated
Assistant Attorney General or Deputy Assistant Attorney General, request an
order under subsection (a) of this section when in his judgment—

(1) the testimony or other information from such individual may be
necessary to the public interest; and

(2) such individual has refused or is likely to refuse to testify or provide
other information on the basis of his privilege against self-incrimination.
4
18 U.S.C. § 6002 states that when a witness refuses, on the basis of his Fifth
Amendment privilege against self-incrimination, to testify or provide other information before a
grand jury and the government grants immunity under this title, then

the witness may not refuse to comply with the order on the basis of his privilege
against self-incrimination; but no testimony or other information compelled under
the order (or any information directly or indirectly derived from such testimony or
other information) may be used against the witness in any criminal case, except a
prosecution for perjury, giving a false statement, or otherwise failing to comply
with the order.

3
On April 19, 2011, the U.S. Attorney and Doe appeared before the district

court.5 The U.S. Attorney requested that the court grant Doe immunity limited to

“the use [of Doe’s] act of production of the unencrypted contents” of the hard

drives. That is, Doe’s immunity would not extend to the Government’s derivative

use of contents of the drives as evidence against him in a criminal prosecution.

The court accepted the U.S. Attorney’s position regarding the scope of the

immunity to give Doe and granted the requested order. The order “convey[ed]

immunity for the act of production of the unencrypted drives, but [did] not convey

immunity regarding the United States’ [derivative] use” of the decrypted contents

of the drives.

After the hearing adjourned, Doe appeared before the grand jury and refused

to decrypt the hard drives. The U.S. Attorney immediately moved the district

court for an order requiring Doe to show cause why Doe should not be held in

civil contempt. The court issued the requested order, requiring Doe to show cause

for his refusal to decrypt the hard drives. Doe, responding, explained that he

invoked his Fifth Amendment privilege against self-incrimination because the

Government’s use of the decrypted contents of the hard drives would constitute

5
Doe appeared without counsel at this hearing and the show cause hearing held later that
day.

4
derivative use of his immunized testimony, use not protected by the district court’s

grant of immunity.6 An alternative reason Doe gave as to why the court should

not hold him in contempt was his inability to decrypt the drives. The court

rejected Doe’s alternative explanations, adjudged him in contempt of court, and

ordered him incarcerated. Doe now appeals the court’s judgment.

We review the district court’s findings of relevant facts for clear error, see

United States v. Doe, 465 U.S. 605, 613–14, 104 S. Ct. 1237, 1243, 79 L. Ed. 2d

552 (1984) (stating that the Court would not overturn findings of fact unless they

had no support in the record), and review the district court’s application of the

Fifth Amendment privilege de novo, United States v. Hernandez, 141 F.3d 1042,

1049 (11th Cir. 1998). Part I briefly reviews the relevant factual background and

procedural history of the case. Part II discusses the merits of Doe’s Fifth

Amendment claim. Part III upholds Doe’s invocation of his Fifth Amendment

right.7

6
As indicated supra note 5, Doe appeared before the court without counsel. Our
statement of Doe’s explanation for invoking the Fifth Amendment expresses the gist of Doe’s
position, not the precise words he used.
7
Because we hold that the district court erroneously concluded that Doe was not
protected by the Fifth Amendment in his refusal to comply with the court order, we need not
address his other points of error.

5
This case began with the lawful seizure of seven pieces of digital media

during the course of a child pornography investigation. In March 2010, law

enforcement officials began an investigation of an individual using the

YouTube.com account [redacted] whom the Government suspected of sharing

explicit materials involving underage girls. During the course of their

investigation, officers from the Santa Rosa County (Florida) Sheriff’s office

obtained several internet protocol (“IP”) addresses from which [redacted] accessed

the internet. Three of these IP addresses were then traced to hotels. Following a

review of the hotels’ guest registries, law enforcement officers found that the sole

common hotel registrant during the relevant times was Doe.

In October 2010, law enforcement officers tracked Doe to a hotel in

California and applied for a warrant to search his room. A judge granted the

application and issued a search warrant, allowing the officers to seize all digital

media, as well as any encryption devices or codes necessary to access such media.

The officers seized seven pieces of digital media: two laptops—a 320-gigabyte

(“GB”) Dell Studio laptop and a 160 GB laptop; and five external hard drives—a

1.5-terabyte (“TB”) Seagate external drive, a 1-TB Western Digital MyPassport

external drive, a 1-TB external drive, a 500-GB Western Digital external drive, a

6
500-GB SimpleTech external drive.8 Federal Bureau of Investigation forensic

examiners analyzed the digital media, but were unable to access certain portions of

the hard drives.

The grand jury subpoena issued because the forensic examiners were

unable to view the encrypted portions of the drives. The subpoena required Doe to

produce the “unencrypted contents” of the digital media, and “any and all

containers or folders thereon.” Doe informed the U.S. Attorney that compliance

with the subpoena would violate his Fifth Amendment privilege against self-

incrimination. It was in an attempt to avoid this constitutional issue that the U.S.

Attorney requested that the district court grant Doe the limited act-of-production

immunity.

Thus, the focus of the motion to show cause hearing on April 19, 2011 was,

in essence, whether the Fifth Amendment would bar the Government from

establishing before a petit jury—say, if Doe were indicted for possession of child

pornography in violation of 18 U.S.C. § 2252—that the decrypted contents (child

pornography) were Doe’s because (1) the hard drives belonged to Doe (which was

8
Testimony from a Government witness at the April 19, 2011 hearing before the district
court identified the two laptops and five external hard drives described above. This is somewhat
inconsistent with the scope of the grand jury subpoena served on Doe, which listed one laptop,
five external hard drives, and one Memorex DVD-R disc. This discrepancy is not relevant to our
decision.

7
not in dispute), and (2) contained child pornography. Doe contended that the

establishment of point (2) would constitute the derivative use of his immunized

grand jury testimony. That is, by decrypting the contents, he would be testifying

that he, as opposed to some other person, placed the contents on the hard drive,

encrypted the contents, and could retrieve and examine them whenever he

wished.9

The critical testimony during the show cause hearing came from forensic

examiner Timothy McCrohan. McCrohan testified that he cloned over 5 TB of

data from the digital media devices—an “enormous amount of data.” He also

testified that over a million pieces of data could be stored on a typical 320-GB

hard drive. McCrohan continued, “So when you’re at five terabytes you’re

looking at 20 times that size. It could be in the multi-millions.” Notably,

McCrohan testified that the forensic examination indicated that the hard drives

had been encrypted with a software program called “TrueCrypt.” Essentially,

TrueCrypt can make certain data inaccessible; in doing so, the program can create

partitions within a hard drive so that even if one part of the hard drive is accessed,

other parts of the hard drive remain secured. Because the hard drive was

9
At the show cause hearing, there was no evidence that Doe was the only person who
had access to his hard drives. Nor was there any evidence that he was capable of decrypting the
drives’ contents.

8
encrypted, the forensic examiners were unable to recover any data.10 Although

they were unable to find any files, McCrohan testified that they believed that data

existed on the still-encrypted parts of the hard drive. In support of this belief, the

Government introduced an exhibit with nonsensical characters and numbers,

which it argued revealed the encrypted form of data that it seeks.

In his testimony on cross-examination by Doe, however, McCrohan

conceded that, although encrypted, it was possible that the hard drives contain

nothing. Doe asked McCrohan, “So if a forensic examiner were to look at an

external hard drive and just see encryption, does the possibility exist that there

actually is nothing on there other than encryption? In other words, if the volume

was mounted, all you would see is blank. Does that possibility exist?” McCrohan

responded: “Well, you would see random characters, but you wouldn’t know

necessarily whether it was blank.”11

The forensic analysis was able to identify two passwords, neither of which

revealed any information when entered. When pressed by Doe to explain why

10
McCrohan stated that he accessed parts of the drive only to find “a blank area of the
hard drive, and there was no data, you know, physically, that we were able to see.”
11
McCrohan’s admission that blank space appears as random characters is supported by
TrueCrypt’s description on its website: “[F]ree space on any TrueCrypt volume is always filled
with random data when the volume is created and no part of the (dismounted) hidden volume can
be distinguished from random data.” Hidden Volume, TrueCrypt,
http://www.truecrypt.org/docs/?s=hidden-volume (last visited January 31, 2012).

9
investigators believed something may be hidden, McCrohan replied, “The scope of

my examination didn’t go that far.” In response to further prodding, “What makes

you think that there are still portions that have data[?],” McCrohan responded,

“We couldn’t get into them, so we can’t make that call.” Finally, when asked

whether “random data is just random data,” McCrohan concluded that “anything is

possible.” At the conclusion of the hearing, the district court held Doe in

contempt and committed him to the custody of the United States Marshal.12

II.

We turn now to the merits of Doe’s appeal. In compelling Doe to produce

the unencrypted contents of the hard drives and then in holding him in contempt

for failing to do so, the district court concluded that the Government’s use of the

unencrypted contents in a prosecution against Doe would not constitute the

derivative use of compelled testimony protected by the Fifth Amendment privilege

against self-incrimination. This is so, the court thought, because Doe’s decryption

and production of the hard drives would not constitute “testimony.” And although

12
The district court announced its decision from the bench and later the same day
memorialized it in a written order. The order adjudged Doe guilty of criminal contempt. A
revised order issued two days later stated that Doe had been adjudged in civil contempt. On
April 21, Doe again appeared before the grand jury. He refused to produce the unencrypted
contents of the hard drives and therefore remained incarcerated in the Marshal’s custody. On
December 15, 2011, after hearing oral argument in Doe’s appeal, we ordered Doe released from
custody.

10
that was the Government’s view as well, the Government nonetheless requested

act-of-production immunity.13 The district court granted this request.

For the reasons that follow, we hold that Doe’s decryption and production

of the hard drives’ contents would trigger Fifth Amendment protection because it

would be testimonial, and that such protection would extend to the Government’s

use of the drives’ contents. The district court therefore erred in two respects.

First, it erred in concluding that Doe’s act of decryption and production would not

constitute testimony. Second, in granting Doe immunity, it erred in limiting his

immunity, under 18 U.S.C. §§ 6002 and 6003, to the Government’s use of his act

of decryption and production, but allowing the Government derivative use of the

evidence such act disclosed.

“[I]n the context of a grand jury inquiry . . . ‘the public . . . has a right to

every man’s evidence,’ except for those persons protected by a constitutional,

common-law, or statutory privilege.” United States v. Nixon, 418 U.S. 683, 709,

94 S. Ct. 3090, 3108, 41 L. Ed. 2d 1039 (1974) (quoting United States v. Bryan,

339 U.S. 323, 331, 70 S. Ct. 724, 730, 94 L. Ed. 884 (1949)). The Fifth

13
If the decryption of the hard drives would not constitute testimony, one must ask,
“Why did the Government seek, and the district court grant, immunity for Doe’s decryption?”
The answer is obvious: Doe’s decryption would be testimonial.

11
Amendment provides, however, that no person “shall be compelled in any criminal

case to be a witness against himself.” U.S. Const. amend. V. Thus, the privilege

against self-incrimination carves out a significant exception to the government’s

ability to obtain every man’s evidence.

An individual must show three things to fall within the ambit of the Fifth

Amendment: (1) compulsion, (2) a testimonial communication or act, and (3)

incrimination. See United States v. Ghidoni, 732 F.2d 814, 816 (11th Cir. 1984)

(citing United States v. Authement, 607 F.2d 1129, 1131 (5th Cir. 1979) (per

curiam)).14 Here, the Government appears to concede, as it should, that the

decryption and production are compelled and incriminatory. We need not pause

any further, as it is obvious that the Government seeks, through the district court’s

order, to compel Doe to decrypt and hand over the contents of the drives, which,

the Government argues, likely contain incriminatory evidence of child

pornography.15

14
In Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir. 1981) (en banc), this
court adopted as binding precedent all of the decisions of the former Fifth Circuit handed down
prior to the close of business on September 30, 1981.
15
As we explain in greater detail in part II.B infra, even if the decryption and production
of the contents of the hard drives themselves are not incriminatory, they are a “link in the chain
of evidence” that is designed to lead to incriminating evidence; this is sufficient to invoke the
Fifth Amendment privilege. Hoffman v. United States, 341 U.S. 479, 486, 71 S. Ct. 814, 818, 95
L. Ed. 1118 (1951) (“The privilege afforded [by the Fifth Amendment] not only extends to
answers that would in themselves support a conviction under a federal criminal statute but
likewise embraces those which would furnish a link in the chain of evidence needed to prosecute

12
The crux of the dispute here is whether the Government sought “testimony”

within the meaning of the Fifth Amendment. The Government claims that it did

not, that all it wanted Doe to do was merely to hand over pre-existing and

voluntarily created files, not to testify. See United States v. Hubbell, 530 U.S. 27,

35–36, 120 S. Ct. 2037, 2043, 147 L. Ed. 2d 24 (2000) (noting that it is a “settled

proposition that a person may be required to produce specific documents even

though they contain incriminating assertions of fact or belief because the creation

of those documents was not ‘compelled’ within the meaning of the privilege”).

We agree—the files, if there are any at all in the hidden portions of the hard

drives, are not themselves testimonial.

Whether the drives’ contents are testimonial, however, is not the issue.

What is at issue is whether the act of production may have some testimonial

quality sufficient to trigger Fifth Amendment protection when the production

explicitly or implicitly conveys some statement of fact. See Fisher v. United

the claimant for a federal crime.”); see also United States v. Hubbell, 530 U.S. 27, 38, 120 S. Ct.
2037, 2044, 147 L. Ed. 2d 24 (2000) (“Compelled testimony that communicates information that
may ‘lead to incriminating evidence’ is privileged even if the information itself is not
inculpatory.” (quoting Doe v. United States, 487 U.S. 201, 208 n.6, 108 S. Ct. 2341, 2346 n.6,
101 L. Ed. 2d 184 (1988)); Kastigar v. United States, 406 U.S. 441, 444–45, 92 S. Ct. 1653,
1656, 32 L. Ed. 2d 212 (1972) (“[The Fifth Amendment privilege] can be asserted in any
proceeding, civil or criminal, administrative or judicial, investigatory or adjudicatory; and it
protects against any disclosures that the witness reasonably believes could be used in a criminal
prosecution or could lead to other evidence that might be so used.” (footnote omitted)).

13
States, 425 U.S. 391, 410, 96 S. Ct. 1569, 1581, 48 L. Ed. 2d 39 (1976) (“The act

of producing evidence in response to a subpoena nevertheless has communicative

aspects of its own, wholly aside from the contents of the papers produced.”).

Thus, we focus on whether Doe’s act of decryption and production would have

been testimonial.

Two seminal cases frame our analysis: Fisher v. United States and United

States v. Hubbell. We start our discussion with this background.

In Fisher, the Court considered two Internal Revenue Service (“IRS”)

investigations, one in the Third Circuit and one in the Fifth Circuit, where the IRS

sought to obtain voluntarily prepared documents the taxpayers had given to their

attorneys. Fisher, 425 U.S. at 393–94, 96 S. Ct. at 1572. In each investigation, the

IRS issued a summons requiring the taxpayer’s attorney to hand over the

documents, which included an accountant’s work papers, copies of the taxpayer’s

returns, and copies of other reports and correspondence. Id. at 394, 96 S. Ct. at

1572–73. When the attorney refused to comply with the summons on the ground

that the documents were privileged and, moreover, protected by his Fifth

Amendment’s privilege against self-incrimination, the IRS brought an

enforcement action in district court. Id. at 395, 96 S. Ct. at 1573; see also United

14
States v. Fisher, 352 F. Supp. 731 (E.D. Pa. 1972) and United States v. Kasmir,

No. CA 3-6973D (N.D. Tex. Mar. 3, 1973).16 In both cases, the district court

granted relief, ordering the attorney to comply with the summons, and its decision

was appealed.17 Id.

After granting certiorari, the Supreme Court made short shrift of the

attorneys’ argument that the Fifth Amendment protected them from producing the

documents in their possession, holding that they could not invoke the privilege.

425 U.S. at 397–402, 96 S. Ct. at 1574–1576. Turning to the taxpayers’ privilege,

the Court treated the taxpayers as retaining possession of the documents.18 Id. at

16
The taxpayer intervened as a party in Fisher, and asserted his Fifth Amendment
privilege against self-incrimination; the taxpayer did not intervene in Kasmir. 425 U.S. at 395,
96 S. Ct. at 1573.
17
In Fisher, the attorney and the intervening taxpayer appealed. In Kasmir, only the
attorney appealed. The Third Circuit affirmed, United States v. Fisher, 500 F.2d 683 (3d Cir.
1974), and the Fifth Circuit reversed, United States v. Kasmir, 499 F.2d 444 (5th Cir. 1974). 425
U.S. at 395, 96 S. Ct. at 1573. To resolve the conflict, the Supreme Court granted certiorari in
both cases. See Fisher v. United States, 420 U.S. 906, 95 S. Ct. 824, 42 L. Ed. 2d 835 (1975)
granting cert United States v. Kasmir, 499 F.2d 444 (5th Cir. 1974) and United States v. Fisher,
500 F.2d 683 (3d Cir. 1974).
18
The Court said this:

Since each taxpayer transferred possession of the documents in question from
himself to his attorney in order to obtain legal assistance in the tax investigations
in question, the papers, if unobtainable by summons from the client, are
unobtainable by summons directed to the attorney by reason of the attorney-client
privilege. We accordingly proceed to the question whether the documents could
have been obtained by summons addressed to the taxpayer while the documents
were in his possession. The only bar to enforcement of such summons asserted by
the parties or the courts below is the Fifth Amendment's privilege against

15
405, 96 S. Ct. at 1578. It then held that the taxpayers’ act of production itself

could qualify as testimonial if conceding the existence, possession and control,

and authenticity of the documents tended to incriminate them. Id. at 410, 96 S. Ct.

at 1581. In the cases before it, though, the Court concluded that the act of

producing the subpoenaed documents would not involve testimonial self-

incrimination because the Government was in “no way relying on the truth telling

of the taxpayer.” Id. at 411, 96 S. Ct. at 1581 (internal quotation marks omitted).

This explanation became known as the “foregone conclusion” doctrine. The Court

expressed it thusly:

It is doubtful that implicitly admitting the existence and possession of
the papers rises to the level of testimony within the protection of the
Fifth Amendment . . . . Surely the Government is in no way relying on
the “truth telling” of the taxpayer to prove the existence of or his
access to the documents. The existence and location of the papers are
a foregone conclusion and the taxpayer adds little or nothing to the
sum total of the Government’s information by conceding that he in
fact has the papers. Under these circumstances by enforcement of the
summons “no constitutional rights are touched. The question is not
of testimony but of surrender.”

self-incrimination.

Id. at 405, 96 S. Ct. at 1578.

16
Id. (quoting In re Harris, 221 U.S. 274, 279, 31 S. Ct. 557, 558, 55 L. Ed. 732

(1911) (citation omitted).19

The Court reasoned that, in essence, the taxpayer’s production of the

subpoenaed documents would not be testimonial because the Government knew of

the existence of the documents, knew that the taxpayer possessed the documents,

and could show their authenticity not through the use of the taxpayer’s mind, but

rather through testimony from others. Id. Where the location, existence, and

authenticity of the purported evidence is known with reasonable particularity,20 the

contents of the individual’s mind are not used against him, and therefore no Fifth

Amendment protection is available.

Twenty-four years after Fisher, the Court decided Hubbell. In Hubbell, a

grand jury investigating the activities of Whitewater Development Corporation

19
The “foregone conclusion” doctrine is a method by which the Government can show
that no testimony is at issue. This is related to, but distinct from, the Government’s task in a
criminal case brought against an individual given use and derivative-use immunity to show that
evidence protected by the Fifth Amendment privilege is admissible because the Government
could have obtained it from a “legitimate source, wholly independent of the compelled
testimony.” Kastigar, 406 U.S. at 460, 96 S. Ct. at 1665. If in the case at hand, for example, the
Government could prove that it had knowledge of the files encrypted on Doe’s hard drives, that
Doe possessed the files, and that they were authentic, it could compel Doe to produce the
contents of the files even though it had no independent source from which it could obtain the
files.
20
Both the Ninth and D.C. Circuits have adopted this “reasonable particularity” standard
with regard to the “foregone conclusion” doctrine. See United States v. Ponds, 454 F.3d 313,
320–21 (D.C. Cir. 2006); In re Grand Jury Subpoena, Dated April 18, 2003, 383 F.3d 905, 910
(9th Cir. 2004). We are persuaded by their reasoning and now follow suit.

17
issued a subpoena duces tecum requiring Hubbell to provide eleven categories of

documents. 530 U.S. at 30–31, 120 S. Ct. at 2040. Hubbell invoked the Fifth

Amendment privilege, so the Government obtained a district court order granting

Hubbell § 6002 immunity. Id. at 31, 120 S. Ct. at 2040. Hubbell complied with

the subpoena and turned over 13,120 pages of documents. Id.

The grand jury subsequently returned a ten-count indictment charging

Hubbell with several federal crimes. Id. at 31, 120 S. Ct. at 2041. Asserting that

the Government could not convict him without the immunized documents,

Hubbell moved the district court to dismiss the indictment. Id. at 31–33, 120 S.

Ct. at 2041. The court held a hearing, found that the Government could not show

that it had knowledge of the contents of the documents from a source independent

of the documents themselves, and dismissed the indictment. The Government

appealed the dismissal. Id. at 31–32, 120 S. Ct. at 2041.21

21
The court of appeals vacated the dismissal and remanded the case with the instruction
that the district court determine whether the Government could show knowledge of the existence
and authenticity of the documents and the defendant’s possession or control of them, not whether
it knew of the contents of the documents. Hubbell, 530 U.S. at 33–34, 120 S. Ct. at 2041. On
remand, the Government conceded that it could not prove the requisite level of knowledge and,
instead, entered into a plea agreement that provided for the dismissal of the charges against
Hubbell unless the Supreme Court, granting the Government’s petition for a writ of certiorari,
ruled that his act of production was not “a significant bar” to the prosecution. Id. at 33, 120 S.
Ct. at 2042.

18
The Supreme Court granted a writ of certiorari. Id. at 34, 120 S. Ct. at

2042. The Court held that Hubbell’s act of production was sufficiently testimonial

to trigger Fifth Amendment protection, as knowledge of the implicit testimonial

facts associated with his act of production was not a foregone conclusion. Id. at

44–45, 120 S. Ct. at 2047–48. In so holding, the Court distinguished Fisher:

Whatever the scope of this “foregone conclusion” rationale, the facts
of this case plainly fall outside of it. While in Fisher the Government
already knew that the documents were in the attorneys’ possession
and could independently confirm their existence and authenticity
through the accountants who created them, here the Government has
not shown that it had any prior knowledge of either the existence or
the whereabouts of the 13,120 pages of documents ultimately
produced by respondent. The Government cannot cure this
deficiency through the overbroad argument that a businessman such
as respondent will always possess general business and tax records
that fall within the broad categories described in this subpoena.

Id. at 44–45, 120 S. Ct. at 2048. In Fisher, therefore, the act of production was not

testimonial because the Government had knowledge of each fact that had the

potential of being testimonial. As a contrast, the Court in Hubbell found there was

testimony in the production of the documents since the Government had no

knowledge of the existence of documents, other than a suspicion that documents

19
likely existed and, if they did exist, that they would fall within the broad

categories requested.22 See id. at 44–45, 120 S. Ct. at 2047–48.

Drawing out the key principles from the Court’s two decisions, an act of

production can be testimonial when that act conveys some explicit or implicit

statement of fact that certain materials exist, are in the subpoenaed individual’s

possession or control, or are authentic. See id. at 36 & n.19, 120 S. Ct. at 2043 &

n.19. The touchstone of whether an act of production is testimonial is whether the

government compels the individual to use “the contents of his own mind” to

explicitly or implicitly communicate some statement of fact. Curcio v. United

States, 354 U.S. 118, 128, 77 S. Ct. 1145, 1151, 1 L. Ed. 2d 1225 (1957).

Put another way, the Court has marked out two ways in which an act of

production is not testimonial.23 First, the Fifth Amendment privilege is not

triggered where the Government merely compels some physical act, i.e. where the

22
The Court then held that, in light of the grant of immunity for the testimonial act of
production, the Government could not introduce the contents of the documents in a later
prosecution without showing “that the evidence it used in obtaining the indictment and proposed
to use at trial was derived from legitimate sources ‘wholly independent’ of the testimonial aspect
of respondent’s immunized conduct in assembling and producing the documents described in the
subpoena.” Hubbell, 530 U.S. at 45, 120 S. Ct. at 2048. Because the Government could not
make that showing, the use of the documents derived directly or indirectly from the testimonial
act of production violated the respondent’s Fifth Amendment privilege. Id. This aspect of the
holding is relevant to part II.B, discussed infra.
23
The Government puts forth, at various times, both arguments in its answer brief in this
appeal.

20
individual is not called upon to make use of the contents of his or her mind. The

most famous example is the key to the lock of a strongbox containing documents,

see Hubbell, 530 U.S. at 43, 120 S. Ct. at 2047 (citing Doe v. United States, 487

U.S. 201, 210 n.9, 108 S. Ct. 2341, 2347 n.9, 101 L. Ed. 2d 184 (1988)), but the

Court has also used this rationale in a variety of other contexts.24 Second, under

the “foregone conclusion” doctrine, an act of production is not testimonial—even

if the act conveys a fact regarding the existence or location, possession, or

authenticity of the subpoenaed materials—if the Government can show with

“reasonable particularity” that, at the time it sought to compel the act of

production, it already knew of the materials, thereby making any testimonial

aspect a “foregone conclusion.”

With this framework in hand, we turn to the facts of this case. We hold that

the act of Doe’s decryption and production of the contents of the hard drives

24
See e.g., United States v. Dionisio, 410 U.S. 1, 7, 93 S. Ct. 764, 768, 35 L. Ed. 2d 67
(1973) (holding that providing a voice exemplar is not testimonial); Gilbert v. California, 388
U.S. 263, 266, 87 S. Ct. 1951, 1953, 18 L. Ed. 2d 1178 (1967) (concluding that providing a
handwriting exemplar is not testimonial); United States v. Wade, 388 U.S. 218, 222–23, 87 S.
Ct. 1926, 1930, 18 L. Ed. 2d 1149 (1967) (holding that standing in a lineup is not testimonial);
Schmerber v. California, 384 U.S. 757, 765, 86 S. Ct. 1826, 1833, 16 L. Ed. 2d 908 (1966)
(concluding that furnishing a blood sample is not testimonial); Holt v. United States, 218 U.S.
245, 252–53, 31 S. Ct. 2, 6, 54 L. Ed. 1021 (1910) (determining that wearing particular clothing
is not testimonial).

21
would sufficiently implicate the Fifth Amendment privilege. We reach this

holding by concluding that (1) Doe’s decryption and production of the contents of

the drives would be testimonial, not merely a physical act; and (2) the explicit and

implicit factual communications associated with the decryption and production are

not foregone conclusions.

First, the decryption and production of the hard drives would require the use

of the contents of Doe’s mind and could not be fairly characterized as a physical

act that would be nontestimonial in nature. We conclude that the decryption and

production would be tantamount to testimony by Doe of his knowledge of the

existence and location of potentially incriminating files; of his possession, control,

and access to the encrypted portions of the drives; and of his capability to decrypt

the files.

We are unpersuaded by the Government’s derivation of the key/combination

analogy in arguing that Doe’s production of the unencrypted files would be

nothing more than a physical nontestimonial transfer. The Government attempts

to avoid the analogy by arguing that it does not seek the combination or the key,

but rather the contents. This argument badly misses the mark. In Fisher, where

the analogy was born, and again in Hubbell, the Government never sought the

“key” or the “combination” to the safe for its own sake; rather, the Government

22
sought the files being withheld, just as the Government does here. Hubbell, 530

U.S. at 38, 120 S. Ct. at 2044 (trying to compel production of documents); Fisher

v. United States, 425 U.S. at 394–95, 96 S. Ct. at 1572–73 (seeking to access

contents possessed by attorneys). Requiring Doe to use a decryption password is

most certainly more akin to requiring the production of a combination because

both demand the use of the contents of the mind, and the production is

accompanied by the implied factual statements noted above that could prove to be

incriminatory. See Hubbell, 530 U.S. at 43, 120 S. Ct. at 2047. Hence, we

conclude that what the Government seeks to compel in this case, the decryption

and production of the contents of the hard drives, is testimonial in character.

Moving to the second point, the question becomes whether the purported

testimony was a “foregone conclusion.” We think not. Nothing in the record

before us reveals that the Government knew whether any files exist or the location

of those files on the hard drives; what’s more, nothing in the record illustrates that

the Government knew with reasonable particularity that Doe was even capable of

accessing the encrypted portions of the drives.

To support its position, the Government points to McCrohan’s testimony. It

states in its answer brief that “[h]ere, the government knows of the ‘existence’ and

‘whereabouts’ of the decrypted records it has subpoenaed because the government

23
already physically possesses those records.” Answer Br. at 22. But McCrohan’s

testimony simply does not stretch as far as the Government wishes it would. As an

initial matter, McCrohan admitted on cross-examination that he had no idea

whether there was data on the encrypted drives. Responding to a question from

Doe as to whether the random characters definitively indicated that encrypted data

is present or instead could have indicated blank space, McCrohan conceded,

“Well, you would see random characters, but you wouldn’t know necessarily

whether it was blank.” Moreover, when pressed to answer why investigators

believed data may be hidden, McCrohan replied, “The scope of my examination

didn’t go that far,” and, “We couldn’t get into them, so we can’t make that call.”

Finally, when Doe posed the question of whether “random data is just random

data,” McCrohan concluded that “anything is possible.”

To be fair, the Government has shown that the combined storage space of

the drives could contain files that number well into the millions. And the

Government has also shown that the drives are encrypted. The Government has

not shown, however, that the drives actually contain any files, nor has it shown

which of the estimated twenty million files the drives are capable of holding may

prove useful. The Government has emphasized at every stage of the proceedings

in this case that the forensic analysis showed random characters. But random

24
characters are not files; because the TrueCrypt program displays random

characters if there are files and if there is empty space, we simply do not know

what, if anything, was hidden based on the facts before us. It is not enough for the

Government to argue that the encrypted drives are capable of storing vast amounts

of data, some of which may be incriminating. In short, the Government physically

possesses the media devices, but it does not know what, if anything, is held on the

encrypted drives.25 Along the same lines, we are not persuaded by the suggestion

that simply because the devices were encrypted necessarily means that Doe was

trying to hide something. Just as a vault is capable of storing mountains of

incriminating documents, that alone does not mean that it contains incriminating

documents, or anything at all.

In sum, we think this case is far closer to the Hubbell end of the spectrum

than it is to the Fisher end. As in Hubbell, “the Government has not shown that it

had any prior knowledge of either the existence or the whereabouts of the [files]”

that it seeks to compel Doe to produce. Hubbell, 530 U.S. at 45, 120 S. Ct. at

2048. In Fisher, the Government knew exactly what documents it sought to be

produced, knew that they were in the possession of the attorney, and knew that

25
This situation is no different than if the Government seized a locked strongbox.
Physical possession of the entire lockbox is not the issue; whether the Government has the
requisite knowledge of what is contained inside the strongbox is the critical question.

25
they were prepared by an accountant. 425 U.S. at 411–12, 96 S. Ct. at 1581.

Here, the Government has not shown that it possessed even a remotely similar

level of knowledge as to the files on the hard drives at the time it attempted to

compel production from Doe. Case law from the Supreme Court does not demand

that the Government identify exactly the documents it seeks, but it does require

some specificity in its requests—categorical requests for documents the

Government anticipates are likely to exist simply will not suffice. See Hubbell,

530 U.S. at 45, 120 S. Ct. at 2048 (“The Government cannot cure this [lack of

prior knowledge] through the over broad argument that a businessman such as

respondent will always possess general business and tax records that fall within

the broad categories described in this subpoena.”); Doe, 465 U.S. at 613–14 &

nn.11–13, 104 S. Ct. at 1242–43 & nn.11–13 (holding that the act of producing

vast categories of records was privileged under the Fifth Amendment and could

not be compelled absent a grant of immunity).

The Government tries to analogize this case to In re Boucher, No. 2:06-mj-

91, 2009 WL 424718 (D. Vt. Feb. 19, 2009). The facts of Boucher appear to be

somewhat similar to the facts of this case, but we do not find the Government’s

26
analogy persuasive.26 Like this case, in Boucher the Government sought to

compel a suspect to produce an unencrypted version of a drive on his laptop. Id. at

*1. Previously, the Government had reviewed portions of the encrypted drive with

the suspect but was unable to reopen the drive once it was closed. Id. at *1–2.

During this initial viewing, law enforcement officers examined the encrypted and

unencrypted portions of the suspect’s hard drive. Id. at *2. After observing

images of animated child pornography on the unencrypted portions of the hard

drive, a Special Agent from Immigration and Custom’s Enforcement (ICE) with

experience and special training in recognizing child pornography was called. Id.

The ICE agent examined the computer and saw a file labeled “2yo getting raped

during diaper change,” but was unable to open it. Id. After the suspect navigated

26
In Boucher, border protection officers inspected a car as it crossed the border from
Canada. In re Boucher, No. 2:06-mj-91, 2009 WL 424718, *1–2 (D. Vt. Feb. 19, 2009). After
directing the car into a “secondary inspection,” an officer found a laptop computer in the
backseat, which he was able to search access without a password. Id. at *1. The officer located
40,000 images, some of which appeared to be child pornography based on their file names. Id. at
*1–2. A special agent from ICE was called to continue the investigation. Id. at *2. The ICE
agent was unable to open certain files to view the contents, but was able to determine that they
had been opened at some point previously. Id. The ICE agent then read Boucher his Miranda
rights and began questioning him about child pornography files the agent thought might be on the
computer. Id. Boucher admitted he sometimes inadvertently downloaded images of child
pornography. At the officer’s request, Boucher navigated to the encrypted portion of the laptop’s
hard drive, i.e., the “Z” drive, which the officer searched and viewed several images of suspected
child pornography. Boucher was then arrested. Id. A forensic examination was made of the
computer’s drives. Id. The contents of all but one drive were revealed. Id. The contents of the
“Z” drive had been encrypted. Id. To gain access to the encrypted drive, the Government had a
grand jury issue a subpoena directing Boucher to provide the unencrypted contents of the drive.
Id. Boucher moved to quash, asserting his Fifth Amendment privilege. Id.

27
to the encrypted portion of the hard drive, the ICE agent located and examined

several videos or images that appeared to be child pornography. Id. The district

court concluded that the “foregone conclusion” doctrine applied under those facts

because any testimonial value derived from the act of production was already

known to the Government and therefore added nothing to its case. Id. at *3–4.

The Government correctly notes that Boucher did not turn on the fact that

the Government knew the contents of the file it sought, id. at *3; Fisher and

Hubbell, though, still require that the Government show its knowledge that the

files exist. Thus, while in Boucher it was irrelevant that the Government knew

what was contained in the file “2yo getting raped during diaper change,” it was

crucial that the Government knew that there existed a file under such a name.27 Id.

27
It is because of the Government’s lack of knowledge in this case that we can easily
distinguish another recent decision, United States v. Fricosu, No. 10-cr-00509-REB-02, 2012
WL 182121 (D. Colo. Jan. 23, 2012). In Fricosu, the Government, after seizing a laptop
computer suspected of containing incriminating information, was unable to access certain
encrypted portions of the computer. Id. at *2. The Government sought a court order requiring
Fricosu to produce the unencrypted contents of the computer, and Friscosu invoked her Fifth
Amendment privilege against self-incrimination. Id. The court then concluded that no testimony
was associated with the compelled production of the unencrypted contents of her laptop
computer. Id. at *4. In reaching this conclusion, the court heavily relied upon a tape recording of
a phone call introduced by the Government between Friscosu and another individual, where the
defendant admitted, “[The content at issue] was on my laptop.” Id. at *2. Friscosu later
confirmed in the call that the content existed when she was asked, “It was on your laptop[?],” and
Friscosu responded, “Yes.” Id. Throughout this extensive exchange, Friscosu essentially
admitted every testimonial communication that may have been implicit in the production of the
unencrypted contents. Here, in contrast, the Government does not know whether any files are
present on the encrypted drive; if any, what their location on the drive may be; whether Doe has
access and control to the encrypted drives; and whether Doe is capable of decryption.

28
That is simply not the case here. We find no support in the record for the

conclusion that the Government, at the time it sought to compel production, knew

to any degree of particularity what, if anything, was hidden behind the encrypted

wall.28

In short, we conclude that Doe would certainly use the contents of his mind

to incriminate himself or lead the Government to evidence that would incriminate

him if he complied with the district court’s order. Moreover, the Government has

failed to show any basis, let alone shown a basis with reasonable particularity, for

its belief that encrypted files exist on the drives, that Doe has access to those files,

or that he is capable of decrypting the files. The “foregone conclusion” doctrine

does not apply under these facts.

The Fifth Amendment protects Doe’s refusal to decrypt and produce the

contents of the media devices because the act of decryption and production would

28
To be clear, the Government does not have to show that it knows specific file names.
Knowledge of a file name, like the Government had in Boucher, would be an easy way for the
Government to carry its burden of showing that the existence of the files it seeks is a “foregone
conclusion.” That said, if the Government is unaware of a particular file name, it still must show
with some reasonable particularity that it seeks a certain file and is aware, based on other
information, that (1) the file exists in some specified location, (2) the file is possessed by the
target of the subpoena, and (3) the file is authentic. See United States v. Norwood, 420 F.3d 888,
895–96 (8th Cir. 2005) (applying “foregone conclusion” doctrine even though the Government
could not identify a specific bank account because the Government was able to prove the name
and location of the entity that created the records, introduced payment card numbers, and
produced the details of transactions involving the account). Thus, although the Government need
not know the name of a particular file or account, it still must be able to establish that a file or
account, whatever its label, does in fact exist. Here, the Government was unable to do that.

29
be testimonial, and because the Government cannot show that the “foregone

conclusion” doctrine applies.

The district court still could have compelled Doe to turn over the

unencrypted contents—and held him in contempt if he refused to do so—had the

Government offered and the district court granted Doe constitutionally sufficient

immunity.29 The district court erred in limiting Doe’s immunity under 18 U.S.C.

§§ 6002 and 6003 to the Government’s use of his act of decryption and production

while allowing the Government derivative use of the evidence such act disclosed.

Doe’s immunity was not coextensive with the protections the Fifth Amendment

affords; consequently, he could not have been compelled to decrypt and produce

the contents of the hard drives.

In evaluating the immunity Doe received, we must look beyond the act-of-

production label and ask this question: what conduct was actually immunized and

what use would the Government make of the evidence derived from such conduct

in a future prosecution? The Government stated in its letter served on Doe on

April 7, 2011, and before the district court on April 19, 2011, that it would not use

29
This assumes, of course, that the Government could show that Doe is capable of
decrypting the drives, which is far from clear from this record.

30
Doe’s act of production against him in a future prosecution; but it would use the

contents of the unencrypted drives against him.30 The district court incorporated

the Government’s position in its order granting immunity under 18 U.S.C. § 6002.

The act-of-production immunity, as the Government and the district court framed

it, is not synonymous with use and derivative-use immunity.31 More to the point,

it is not the type of immunity mandated by 18 U.S.C. § 6002. The question thus

30
The Government’s decision to offer only act-of-production immunity was done with an
eye for the future. The act of decrypting the hard drives would not be introduced as evidence
against Doe in a criminal prosecution. But, given the district court’s decision, the derived
evidence would be introduced unless this court reversed in this appeal the district court’s order.
If we upheld the order and Doe moved the court in a subsequent criminal prosecution to bar the
evidence as obtained in violation of the Fifth Amendment, the Government would no doubt
contend that our decision had settled the issue.
31
The immunity statute, 18 U.S.C. § 6002, clearly immunizes both the use of the
testimony itself and any information derived from the testimony. The text of the statute provides
in relevant part that

no testimony or other information compelled under [an immunity] order (or any
information directly or indirectly derived from such testimony or other
information) may be used against the witness in any criminal case, except a
prosecution for perjury, giving a false statement, or otherwise failing to comply
with the order.

(emphasis added).
Squeezed down to its core, the Government in this case tried to split 18 U.S.C. § 6002 in
half—it agreed that “no testimony or other information compelled under the order” could be used
against Doe, in light of the act-of-production immunity, but refused to immunize “any
information directly or indirectly derived from such testimony or other information.” Under our
reading of 18 U.S.C. § 6002, there does not appear to be any provision that allows the
Government to selectively pick and choose which sentences of the immunity statute to employ.
Given the plain language of the statute, read in conjunction with 18 U.S.C. § 6003, the
Government appears to have a choice: give § 6002 immunity or do not give § 6002 immunity.
Putting aside whether it is even possible for the Government to manipulate § 6002 in the manner
it did, we explain infra why this attempt was misguided in this case.

31
becomes, is the act-of-production immunity offered here sufficient to compel Doe

to testify? We hold that the answer is most certainly, no.

In the seminal case on point, Kastigar v. United States, the Court stated:

The constitutional inquiry, rooted in logic and history, as well as in
the decisions of this Court, is whether the immunity granted under
this statute is coextensive with the scope of the privilege. If so,
petitioners’ refusals to answer based on the privilege were unjustified,
and the judgments of contempt were proper, for the grant of immunity
has removed the dangers against which the privilege protects. If, on
the other hand, the immunity granted is not as comprehensive as the
protection afforded by the privilege, petitioners were justified in
refusing to answer, and the judgments of contempt must be vacated.

Kastigar v. United States, 406 U.S. 441, 449, 92 S. Ct. 1653, 1659, 32 L. Ed. 2d

212 (1972) (footnote and citation omitted) (citing McCarthy v. Arndstein, 266

U.S. 34, 42, 45 S. Ct. 16, 17, 69 L. Ed. 158 (1924). The Court then held that §

6002 “immunity from use and derivative use is coextensive with the scope of the

[Fifth Amendment] privilege against self-incrimination.” Id. at 453, 92 S. Ct. at

1661. In so holding, the Court emphasized that such immunity “prohibits the

prosecutorial authorities from using the compelled testimony in any respect.” Id.

Supreme Court precedent is clear: Use and derivative-use immunity

establishes the critical threshold to overcome an individual’s invocation of the

Fifth Amendment privilege against self-incrimination. No more protection is

32
necessary; no less protection is sufficient.32 See id. at 406 U.S. at 460, 92 S. Ct.

1664–65 (“This total prohibition on use [of both direct and derivative evidence]

provides a comprehensive safeguard, barring the use of compelled testimony as an

‘investigatory lead,’ and also barring the use of any evidence obtained by focusing

investigation on a witness as a result of his compelled disclosures.”) (footnote

omitted); see also Hoffman v. United States, 341 U.S. 479, 486, 71 S. Ct. 814, 818

95 L. Ed. 1118 (1951) (“The privilege afforded not only extends to answers that

would in themselves support a conviction under a federal criminal statute but

likewise embraces those which would furnish a link in the chain of evidence

needed to prosecute the claimant for a federal crime.”).

32
The Kastigar Court concluded that transactional immunity—a prohibition on any
future prosecution based on immunized testimony—exceeded the protections offered by the Fifth
Amendment, but that immunity limited to the prohibition on the use of the testimonial evidence
itself, not derivative evidence, offered too little protection to compel production:

We hold that such immunity from use and derivative use is coextensive with the
scope of the privilege against self-incrimination, and therefore is sufficient to
compel testimony over a claim of the privilege. While a grant of immunity must
afford protection commensurate with that afforded by the privilege, it need not be
broader. Transactional immunity, which accords full immunity from prosecution
for the offense to which the compelled testimony relates, affords the witness
considerably broader protection than does the Fifth Amendment privilege. The
privilege has never been construed to mean that one who invokes it cannot
subsequently be prosecuted. Its sole concern is to afford protection against being
“forced to give testimony leading to the infliction of ‘penalties affixed to . . .
criminal acts.’” Immunity from the use of compelled testimony, as well as
evidence derived directly and indirectly therefrom, affords this protection.

Kastigar, 406 U.S. at 453, 92 S. Ct. at 1661 (footnote omitted) (quoting Ullmann v. United
States, 350 U.S. 422, 438–39, 76 S. Ct. 497, 507, 100 L. Ed. 511 (1956)).

33
The Government gave no such immunity in this case. In essence, the

Government attempts to immunize the testimony itself, treating everything else as

fair game. But for the reasons we just noted, the Government cannot obtain

immunity only for the act of production and then seek to introduce the contents of

the production, regardless of whether those contents are characterized as

nontestimonial evidence, because doing so would allow the use of evidence

derived from the original testimonial statement.33

33
The D.C. Circuit, addressing a similar issue, reached the same conclusion. See Ponds,
454 F.3d at 328 (“[N]on-testimonial evidence derived from this testimonial act of production
may not be used under § 6002.”). That court provided a useful analogy to clarify how act-of-
production immunity can be problematic:

[I]f a murder suspect who has been granted immunity is called before a grand jury
and asked whether he committed a murder and where the murder weapon is, his
testimony may not be used against him in a criminal trial. In addition, the
government may not use his testimony to retrieve the weapon for use against the
witness at trial. Even if the government introduced the weapon without indicating
that it learned of its location from the defendant’s immunized grand jury
testimony, only using fingerprints or DNA testing to link the weapon to the
defendant, the weapon would still be barred because it was “directly or indirectly
derived from” compelled testimony. If the police simply happened upon the
weapon through an ongoing investigation, however, the weapon could be used
against the witness because it was “derived from a legitimate source wholly
independent of the compelled testimony.”

Id. at 321 (quoting Kastigar, 406 U.S. at 460, 92 S. Ct. at 1665). We think this is analogous to
the case here. Essentially the Government asks that we compel Doe to provide incriminating
testimony—producing the unencrypted documents. The Government then argues that it will not
use the compelled testimony. The problem, though, is that the contents of the drives would still
be barred because they would be “directly or indirectly derived from” compelled testimony.
Kastigar, 406 U.S. at 453, 92 S. Ct. at 1661 (internal quotation marks omitted). Thus, because
the protection offered by the act-of-production immunity is not coextensive with the Fifth
Amendment, Doe was within his right to refuse to decrypt the drives and the court cannot compel
him to do otherwise.

34
The Court in Hubbell expressly rejected the “manna from heaven” theory,

which contended that if the Government omitted any description of how the

documents were obtained, it would be as if they magically appeared on the

courthouse steps and the Government could use the documents themselves.34 530

U.S. at 33, 42, 120 S. Ct. at 2041–42, 2046–47. The Government, in essence, asks

us to revisit the “manna from heaven” theory. The Supreme Court definitively

foreclosed such an argument; hence, we must decline to consider it.

To conclude, because Doe’s act of production would have testimonial

aspects to it, an order to compel him to produce the unencrypted contents of the

drives would require immunity coextensive with the Fifth Amendment (and §

6002). Immunity coextensive with the Fifth Amendment requires both use and

derivative-use immunity. The Government’s offer of act-of-production immunity

clearly could not provide the requisite protection because it would allow the

34
The Court stated:

It is abundantly clear that the testimonial aspect of respondent’s act of producing
subpoenaed documents was the first step in a chain of evidence that led to this
prosecution. The documents did not magically appear in the prosecutor’s office
like “manna from heaven.” They arrived there only after respondent asserted his
constitutional privilege, received a grant of immunity, and—under the compulsion
of the District Court’s order—took the mental and physical steps necessary to
provide the prosecutor with an accurate inventory of the many sources of
potentially incriminating evidence sought by the subpoena.

Hubbell, 530 U.S. at 42, 120 S. Ct. at 2046–47.

35
Government to use evidence derived from the immunized testimony. Thus,

because the immunity offered here was not coextensive with the Fifth

Amendment, Doe could not be compelled to decrypt the drives.

III.

We hold that Doe properly invoked the Fifth Amendment privilege. In

response, the Government chose not give him the immunity the Fifth Amendment

and 18 U.S.C. § 6002 mandate, and the district court acquiesced. Stripped of

Fifth Amendment protection, Doe refused to produce the unencrypted contents of

the hard drives. The refusal was justified, and the district court erred in adjudging

him in civil contempt. The district court’s judgment is accordingly REVERSED.

SO ORDERED.
