Opinion for the Court filed by Circuit Judge ROGERS.
This аppeal challenges the government’s use of documents produced by Navron Ponds pursuant to a grant of immunity under 18 U.S.C. § 6002. Ponds’ appeal of his convictions for tax evasion and fraud requires the court to address the breadth of that immunity for an act of production that, in its testimonial character, falls somewhere between the response to a fishing expedition addressed in
United States v. Hubbell,
I.
In 1996, Navron Ponds, a criminal defense lawyer, agreed to represent a drug dealer named Jerome Harris.
See, e.g., United States v. Harris,
Maryland Assistant United States Attorney (“MD-AUSA”) Sandra Wilkinson executed a search warrant for Harris’s jail cell to obtain the retainer agreement discussing the Mercedes. Federal Drug Enforcement Administration agents went to Ponds’ apartment complex, Albemarle House, looking for the car. Parked outside were the Mercedes, and in another parking space rented by Ponds, a Porsche with the vanity license plate “I OBJECT.” According to apartment personnel, Ponds drove the Mercedes and his sister, Laura Ponds Pelzer, drove the Porsche. MD-AUSA Wilkinson issued a subpoena duces tecum ordering Ponds to produce seven categories of documents and the Mercedes. When Ponds exрressed his intent to invoke his Fifth Amendment privilege against self-incrimination, Wilkinson revised the subpoena to omit requests that Ponds actually produce the car and that he produce financial and tax records, and filed a motion pursuant to 18 U.S.C. § 6003 for a judicial order authorizing act-of-production immunity under 18 U.S.C. § 6002. The subpoena made six demands of Ponds to produce “any and all documents” from 1996 forward:
1. Referencing use, ownership, possession, custody and/or control of a white Mercedes Benz ...;
2. That refer or relate to payment of legal fees by or on behalf of Jerome Harris whether by cash, currency, or some other form of payment;
3. That refer or relate to any vehicles in the custody or control of Jerome Harris if access to that vehicle was provided to you by any means, direct or indirect; and,
4. That refer or relate to Sloan Solomon, Christinе Privott [Harris’s mother] or Laura P. Pelzer [Ponds’ sister];
5. Any and all correspondence between the Law Offices of Navron Ponds [and courts and prosecutors] in the matter of U.S. v. Jerome Harris, PJM 96-0269;
6. Records of employees of the law Office of Navron Ponds in the time frame of 1996 to the present.
The district court granted the immunity request and ordered Ponds to produce the subpoenaed documents.
Armed with act-of-production immunity, Ponds appeared before the grand jury and produced approximately 300 pages of documents. The documents included records showing that: (1) the Mercedes and Porsche were registered in the name of Ponds’ sister; (2) Ponds had financial accounts with his sister; (3) Ponds and his sister sold a Georgia property they had jointly owned; (4) Ponds possessed money order receipts used to pay for various services, mostly involving the Mercedes; and (5) Ponds had a health insurance document indicating he had purchased insurance for himself and Magdalene Alexander. Ponds also testified before the grand jury, responding to the prosecutors’ questions about the document production, including affirming that the health insurance document was responsive to the subpoena request for documents regarding his employees. Magdalene “Maggie” Alexander, Ponds’ employee, was then called before the grand jury, where she testified about many of the produced documents and in detail about the process by which she helped Ponds produce them.
Soon after Ponds responded to the subpoena
duces tecum,
the Maryland United States Attorney’s Office filed an
ex parte
application it had prepared before the subpoena response with the Maryland federal district court to authorize the Internal
The investigation continued, and in 2001, DC-AUSA Dubester applied for search warrants on the basis of an affidavit provided by Agent Becker that included information first learned in the Maryland grand jury. Based on those applications, the D.C. United States Attorney’s Office secured warrants to search Ponds’ home and office, where Agent Becker seized six boxes of documents. The documents revealed that Ponds had used a tax preparer, and the preparer’s records were subpoenaed, uncovering further details about Ponds’ financial affairs. With these materials and others subpoenaed from financial institutions, Ponds was indicted in the District of Columbia on five counts of tax evasion under 26 U.S.C. § 7201, one count of wire fraud under 18 U.S.C. § 1343, and one count of fraud in the first degree under 22 D.C.Code §§ 3821(a), 3822(a)(1).
Ponds filed a pretrial motion for a hearing pursuant to
Kastigar v. United States,
II.
18 U.S.C. § 6002 provides 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.
This federal witness immunity statute has a constitutional dimension, as the Supreme Court in
Kastigar,
The Fifth Amendment declares that “[n]o person ... shall be compelled in any criminal case to be a witness against himself.” U.S. CONST, amend. V. At one point in our history, this declaration was taken to mean that the government could not compel the production of private papers.
See Boyd v. United States,
Two Supreme Court cases provide the framework for our analysis of the facts and circumstances of this case. In
Fisher,
Hubbell
provides the counterpoint to
Fisher.
In
Hubbell,
the Supreme Court held that Hubbell’s act of producing over 13,000 documents in response to a broad subpoena was sufficiently testimonial to implicate the Fifth Amendment because “the prosecutor needed [Hubbell]’s assistance both to identify potential sources of informatiоn and to produce those sources.”
The Supreme Court distinguished the circumstances in
Hubbell
from those in
Fisher:
“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 produced documents.
Id.
at 44-45,
[T]he government must establish its knowledge of the existence, possession, and authenticity of the subpoenaed documents with ‘reasonable particularity’ before the communication inherent in the act of production can be considered a foregone conclusion. In making this assessment, though, the focus must remain upon the degree to which a subpoena “invades the dignity of the human mind,” and on the quantum of information as to the existence, possession, or authenticity of the documents conveyed via the act of production.
United States v. Hubbell,
Once it is clear that an act of production is sufficiently testimonial to be protected by the Fifth Amendment’s privilege against self-incrimination, the question remains how the government may use the compelled testimony and information derived therefrom in a later prosecution of the witness. In
Kastigar,
With oral testimony, the bar on derivative use is easy to imagine. For example, if 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” compеlled 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.”
Kastigar,
With act-of-production immunity, the key question is whether, despite the compelled testimony implicit in the production, the government remains free to use the contents of the (non-testimonial) produced documents. In
Hubbell,
the Supreme Court rejected the “manna from heaven” theory
2
by holding the use of the contents of produced documents to be a barred derivative use of the compelled testimonial act of production. The Court did so by stating that it “cannot accept the Government’s submission that [Hubbell’s] immunity did not preclude its derivative use of the
produced documents
” as it “was only through [Hubbellj’s truthful reply to the subpoena that the Government received the incriminating documents of which it made ‘substantial use ... in the investigation that led to the indictment.’ ”
Hubbell,
After determining
what
may not be used against the witness-defendant, the further question remains
how
that information may not be used. The direct introduction of immunized information as evidence at trial would be a prohibited “use.”
See Hubbell,
Taken together, the bar on the use of information derived from a testimonial act of production by a witness with § 6002 immunity and the breadth of that bar create real risks for prosecutors planning on prosecuting those whom they subpoena. “The decision to seek use immunity necessarily involves a balancing of the Government’s interest in obtaining information against the risk that immunity will frustrate the Government’s attempts to prosecute the subject of the investigation.”
Doe,
III.
The central question on appeal is whether the district court’s reliance on “a sharp distinction” between the testimonial aspect of producing documents and the contents of the documents,
see Ponds,
A.
It is true that in
Hubbell
the Supreme Court drew a distinction between protected testimony as to the existence, location, and authenticity of documents inherent in the act of production and the unprotected contents of the documents themselves.
See Hubbell,
The “sharp distinction” upon which the district court relied becomes less relevant, however, when a court proceeds to “the cоnceptually separate and temporally subsequent
Kastigar
inquiry.”
Hubbell,
The government concedes that the contents of subpoenaed documents can sometimes be off-limits, describing the subpoеna response in Hubbell as “sufficiently testimonial (as to the documents’ existence and location) to be privileged, and to taint the contents of the documents themselves.” Appellee’s Br. at 25. The government attempts to minimize the distinction that the district court drew between contents and act of production. It contends that the district court understood that the act of production could taint the contents of produced documents, but found that Ponds’ act of production did not taint the contents of the produced materials because his act of production did not make the extensive testimonial representations that Hubbell did. The government reads the district court as understanding that act-of-production immunity could reach the contents of documents, but that in this case, immunity did not reach the documents’ contents.
The district court distinguished Ponds’ case from
Hubbell
in finding “the degree of interpretation, locating, cataloging and аssembling of documents so important in
Hubbell
... simply not demanded by the narrow subpoena at issue here.”
Ponds,
B.
Applying the lessons of
Fisher
and
Hubbell
to determine whether Ponds’ act of production is better characterized as “testimony” or “surrender,” we begin by addressing the threshold question of whether the government has “establish[ed] its [pre-subpoеna] knowledge of the existence, possession, and authenticity of the subpoenaed documents with ‘reasonable particularity’ ” such that “the communication inherent in the act of production can be considered a foregone conclusion.”
Hubbell,
As the critical inquiry is whether the government can show it had such “prior knowledge of either the existence or the whereabouts,”
Hubbell,
The existence and location of some subpoenaed documents were a foregone conclusion: For instance, the government must have known of the existence of the documents in Subpoena Demand No. 5, “[a]ny and all correspondence between the Law Offices of Navron Ponds [and courts and prosecutors] in the matter of U.S. v. Jerome Harris,” because it was a party to that correspondence. And the government knew of the existence of documents referring to “payment of legal fees by or on behalf of Jerome Harris” (Subpoena Demand No. 2) because it had alreаdy seized a copy of Harris’s retainer agreement from his prison cell. The failure of the government to identify each produced document specifically is of no moment. To be consistent with Fisher, in which there is no indication that the government knew of each document within the set of documents of which it was aware, the “reasonable particularity” standard cannot demand that the subpoena name every scrap of paper that is produced. Because the government already had sufficient knowledge about the Harris documents, Ponds was simply surrendering them, not testifying, by complying with those demands in the subpoena.
The government’s prior knowledge of the existence or location of other subpoenaed documents has not been established. First, the government has not shown any prior knowledge that documents regarding the “use, ownership, possessiоn, custody and/or control of a white Mercedes Benz” (Subpoena Demand No. 1) were in existence or in Ponds’ possession. Before the subpoena, the government knew that the Mercedes was normally parked at Ponds’ apartment and was registered to his sister.
See Ponds,
Similarly, the government has not shown prior knowledge of the existence or location of documents relating to Ponds’ sister,
In addition, the government has not shown that it had any prior knowledge of the existence or location of “[r]ecords of employees of the law Office of Navron Ponds in the time frame of 1996 to the present” (Subpoena Demand No. 6). The district court’s determination that the existence and location of these documents was a foregone conclusion was based on pure inference: “[T]he Court concludes that it was a foregone conclusion in this day and age in the Washington area that a sole practitioner would have some staff, even if part-time or temporary, to assist him in his legal practice. Moreover, it was also a foregone conclusion that certain administrative documents, including health care forms, would exist with respect to such staff, and would be in defendant’s possession.”
Ponds,
The request for documents relating to any employees — when the government did not know whether Ponds had employees, much less whether he had specific documents relating to them — “was tantamount to answering a series of interrogatories,”
id.
at 41,
The face of the subpoena also displays the government’s lack of knowledge when it asks for documents that “refer or relate
In sum, the government has failed to show with reasonable particularity that it had prior knowledge of the existence and location of many of the subpoenaed documents necessary to render their existence and location a “foregone conclusion.” The Supreme Court has not defined the precise amount of cognition on the part of an immunized party necessary to render a subpoena response “testimonial,” but it is clear here that, as in
Hubbell,
the government “nеeded [Ponds’] assistance both to identify potential sources of information and to produce those sources,”
Hubbell,
C.
Having determined that portions of Ponds’ act of production were testimonial, the next question is whether the government violated its immunity agreement with Ponds by using that “testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information).” 18 U.S.C. § 6002. “When the government proceeds to prosecute a previously immunized witness, it has ‘the heavy burden of proving that all of the evidence it proposes to use [or has used] was derived from legitimate independent sources.’ ”
North,
Ponds contends that the government violated his Fifth Amendment privilege by using the produced documents at two points: in establishing its evasion theory of the case and in crafting the search warrant application. Of course, § 6002 is “a comprehensive safeguard, barring the use of compelled testimony as an ‘investigatory lead,’ and also bаrring the use of any evidence obtained by focusing investigation on a witness as a result of his compelled disclosures.”
Kastigar,
The district court noted the “government concession] that, to a limited extent, the IRS made use of some documents the defendant had produced to the grand jury to support the search warrant affidavits.”
Ponds,
Nevertheless, although the district court’s findings regarding the use of immunized documents make clear that some impermissible derivative use occurred, the degree of the
Kastigar
violation is less apparent. The government is free to use a piece of information that appears in an immunized document if it can accomplish its “affirmative duty” of proving that the information was “derived from a legitimate source wholly independent of the cоmpelled testimony.”
Kastigar,
Determining the precise manner in which Ponds’ rights were violated is essential because the finding of a
Kastigar
violation does not resolve Ponds’ challenge to his convictions. “Dismissal of the indictment or vacation of the conviction is not necessary where the use is found to be harmless beyond a reasonable doubt,”
North,
The government has not shown that it had reasonably particular knowledge of the existence and location of some of the documents it subpoenaed from Ponds. It has conceded that, to some extent, it used those documents to prepare its prosecution of Ponds. Accordingly, we reverse the judgment of conviction and we remand the case to the district court to consider the degree of the government’s impermissible use and to determine whether that use was harmless beyond a reasonable doubt. 3
Notes
. In addition to the counts on which Ponds was indicted, Ponds was convicted of five "failure-to-file” counts which were charged by information. See 26 U.S.C. § 7203. The district court vacated those convictions without prejudice to a government motion to reinstate them if the convictions at issue here are vacated on appeal.
. This theory states that “the act of production shields the witness from the use of any information (resulting from his subpoena response) beyond what the prosecution would receive if the documents appeared in the grand jury room or in his office unsolicited and unmarked, like manna from heaven.”
Hubbell,
. If the district court determines upon remand that the convictions of tax evasion and fraud should stand, then as Ponds contends and the government agrees, the district court must determine, in light of its treatment of the sentencing guidelines as mandatory,
