Circuit Judge.
Respondents-Appellants taxpayer, a sole proprietor, and his attorney appeal from the district court’s order,
I.
The facts are not in dispute. During 1976-78, the taxpayer, Beligratis, operated two hairdressing salons in the Chicago area as a sole proprietor. During this time, Beli-gratis employed an accounting firm to prepare his income statements, balance sheets, profit and loss statements, federal payroll tax returns, personal income tax returns, W-2 forms and federal unemployment tax returns; these reports were generated through Beligratis’ submission of carbon copies of checks written by him, records of his cash disbursements, bank account statements with cancelled checks, and a sheet recording the monthly sales of each salon. The Chicago District of the IRS began an examination of Beligratis’ federal income tax returns for 1976-78, and a revenue agent reviewed the records of the two sole proprietorships with the result that the case was referred to the IRS Criminal Investigative Division.
Special Agent Gerald Padar of that Division was assigned to the case and in early April, 1980 requested the taxpayer’s records concerning his personal finances and business transactions during the investigated period. However, shortly thereafter, Beli-gratis transferred the - requested records, which were in his accounting firm’s possession, to his lawyer, respondent Porter. In August, 1980, Special Agent Padar issued an IRS summons to Porter requiring that she produce records relating to the taxpayer’s personal cheeking and savings accounts and his business checking accounts, including bank statements, cancelled checks, deposit slips, statements of interest earned, statements of interest paid on personal and business loans, cash receipts journals, cash disbursement journals, appointment books or records of services provided, tax withholding forms, and other tax-related records. Respondent Porter appeared before Padar and refused to comply with the summons, claiming that the government already possessed some of these items and that the others were protected by the attorney-client privilege because these items would have enjoyed Fifth Amendment protection in Beligratis’ hands. In September, *1399 1980, Padar issued a second summons to Porter, again ordering production of specified business records; Porter again invoked the attorney-client privilege with respect to the records demanded. In December, 1980, Padar issued a third summons, this time against Beligratis, ordering a production of the same documents specified in the previous summonses. In January, 1981, the taxpayer and Porter met with Padar and refused to comply with the third summons, this time directly asserting Beligratis’ Fifth Amendment privilege with respect to these materials.
In February, 1983, the district court ordered respondents to surrender the summoned materials (except for the appointment books)
1
to Padar. In its previous findings, the district court assumed, and it is not disputed here, that the requested materials were turned over to Porter to facilitate legal advice rather than simply to evade the summons, and thus measured the scope of the attorney-client privilege by the Fifth Amendment privilege attaching to the documents had they been in Beligratis’ possession, the procedure mandated in
Fisher
v.
United States,
The district court expressed greater difficulty, however, in determining whether the cancelled checks, deposit slips and appointment books retained residual Fifth Amendment protection in light of the Supreme Court’s explicit reservation in
Fisher,
Respondents then moved for a stay pending appeal; the stay was granted only with respect to the checks, deposit slips and appointment books. Following this ruling, all of the summoned items except for the checks, deposit slips and appointment books were surrendered by respondents to the IRS.
II.
We must first address the scope of the present appeal. Respondents claim that, even though they have surrendered each of the summoned items except the checks and deposit slips (and the appointment books whose protection is uncontested by the government), their Fifth Amendment claims with respect to the surrendered items are not moot. This court and other circuits, however, have flatly held that a
*1400
taxpayer’s submission of material in compliance with an IRS summons renders any constitutional objections to that compelled submission moot.
United States v. Kis,
Respondents, however, argue that we should now fashion a special exception to the mootness doctrine by incorporating into it the doctrine of
Perlman v. United States,
But application of the
Perlman
exception here is without any basis, for that is a doctrine of “ripeness,” not mootness. It is designed to interpose review to prevent the kind of irrevocable disclosure which has already occurred here. Accordingly, this court has held that the
Perlman
doctrine itself may not apply where, as here, a substantial disclosure to the government of the information sought to be protected has already occurred.
United States v. Calandra,
III.
We now turn to the substance of this appeal: whether the taxpayer’s can-celled checks and bank deposit slips are entitled to Fifth Amendment protection under
Fisher
v.
United States,
In
Fisher,
the Supreme Court held that sole proprietor taxpayers were not entitled, through their attorneys, to assert a Fifth Amendment privilege to resist an IRS subpoena of their accountants’ workpapers (including analyses by the accountants of the taxpayers’ cancelled checks and deposit slips). The Supreme Court eschewed a content-based approach to Fifth Amendment protection of subpoenaed documents, noting that since the documents were not themselves
composed
under the threat of compulsion, the “taxpayer cannot avoid compliance with the subpoena merely by asserting that the item of evidence which he is required to produce contains incriminatory writing, whether his own or that of someone else.”
The district court here applied Fisher’s three-pronged test in inquiring into possible testimonial communications inherent in compliance with all of the summonses. It held that Fisher did not protect the bulk of the records which were prepared by Beli-gratis’ accountant. The court reasoned that the existence and location of the documents were not in issue, and were indeed admitted by respondents, and that the possibility of their implicit authentication was not significant in view of the fact that their authenticity was more authoritatively established by the accountant who authored them.
However, the district court took a different approach with respect to the cancelled checks and deposit slips. The court stated that it viewed the prior and controlling questions with respect to these items to be 1) whether the
Fisher
doctrine was applicable at all to a taxpayer’s “private papers,” or, stated differently, whether
Boyd v. United States,
Although we do not find the considered analysis of the district court to be unfounded, we feel compelled to express another view. Without having to reach the question of the continuing viability of the Boyd “private papers” doctrine, we believe that the application of FisheFs “implicit testimony” analysis to the case at bar yields the conclusion that the cancelled checks and deposit slips are entitled to limited Fifth Amendment protection.
We base this conclusion not on any implied verification of the existence and location of these documents which ensues from their production. As in
Fisher,
the existence and location of the disputed documents is not in issue, and the respondents concede this in their brief. But here, unlike in
Fisher,
the “implicit authentication” ensuing from the production of the documents is undeniable. The Supreme Court held in
Fisher
that the danger of implied authentication of an accountant’s analysis through the taxpayer’s production of them was nonexistent since “the taxpayer did not prepare the papers and could not vouch for their accuracy” and thus such “production would express nothing more than the taxpayer’s belief that the papers are those described in the subpoena,”
Other courts have agreed with us that
Fished s
“implied authentication” test affords protection to business records generated by a sole proprietor taxpayer.
See, e.g., United States v. Doe,
IV.
Having determined that the act of production of Beligratis’ cancelled checks and deposit slips results in compelled “testimony” protected under the Fifth Amendment, it does not follow that the contents of these documents enjoy any such protection; indeed, Fisher instructs us to the contrary. We are thus confronted with the problem of fashioning a remedy which would allow the government to use the contents of the documents without permitting a breach of Beli-gratis’ right to be protected from his implicit authentication of them in violation of his Fifth Amendment rights.
The First Circuit has taken the lead in suggesting how such a remedy might be fashioned. It has indicated that the proper course is to permit the government access to the protected records but only upon the condition that the government grant statutory use immunity with respect to the “testimonial” aspects of the documents’ production.
In Re Grand Jury Proceedings United States (Martinez),
*1404
We think that this somewhat unorthodox approach has much to recommend it, but we are concerned that the grant of use immunity alone may not be adequate to fully protect Beligratis’ Fifth Amendment privilege, for there is nothing in the statutory “use immunity” concept which would prohibit the government’s
reference
to (as opposed to evidentiary “use” of) Beligratis’ having produced the documents; indeed, permitting such reference is the very advantage that the government obtains in the normal case of witness use immunity. Under the First Circuit approach, as we understand it, then, there is no guarantee that the grand or petit jury may not ultimately be swayed by the implicit authentication stemming from Beligratis’ documentary production rather than by alternative means of authentication,
see United States v. Hinton,
We therefore would specifically require that, before the checks and deposit slips may be obtained for further investigation, not only must Beligratis be granted statutory use immunity with respect to these documents, but also the court must fashion a protective order forbidding the government from referring in any way before the grand jury or at trial to the fact that Beligratis produced the documents. Such a protective order will, if properly designed and enforced, effectively shield Beligratis from any infringement of his Fifth Amendment rights, for only the compelled documentary contents, rather than his implied “testimony” via production, will be available. We need not at this point spell out the details of such a protective order, especially as we are unfamiliar with the substance of the investigation and probable evidentiary configuration of the instant case. That task is better left to the district court upon remand.
V.
We consider briefly the government's alternative argument that any Fifth Amendment protection attaching to the checks and deposit slips under
Fisher
and its progeny is eclipsed because these documents fall under the “required records” exception to the privilege, an exception enunciated in
Shapiro v. United States,
Under the “required records” doctrine, documents may be required to be produced when the government requires the preservation of those documents pursuant to an essentially regulatory scheme, and the records have also assumed “public aspects” which render them analogous to public documents.
Shapiro,
The matter stands very differently here. While the Internal Revenue Code, 26 U.S.C. § 6001 requires the taxpayer to “keep such records ... as the [IRS] may from time to time prescribe” and the IRS has, pursuant to this authority, mandated that taxpayers “keep such permanent books of account or records, including inventories, as are sufficient to establish the amount of gross income, deductions, credits, or other matters required to be shown ... in any return ... ”, Treas.Reg. § 1.6001-1(a), T.D. 7577, 1979-
More importantly, the very nature of the limited taxpayer-government relationship is, we think, insufficient to imbue the taxpayer’s cancelled checks and deposit slips with “public aspects” as required under
Shapiro.
Unlike the transaction records which the Emergency Price Control Act provided would be routinely available to the government as a condition of the business’ operation, a sole proprietor’s checks and bank transactions are inspected by revenue authorities only in the unusual situation of an audit. This rarely attempted access hardly transforms the gamut of an individual businessman’s financial records into an extension of the public archives. As the Supreme Court noted in
Marchetti
in finding that the record-keeping provisions of a federal occupational tax scheme did not imbue those records with “public aspects” in the
Shapiro
sense, “The Government’s anxiety to obtain information known to a private individual does not without more render that information public; if it did, no room would remain for the application of [the Fifth Amendment]. Nor does it stamp information with a public character that the Government has formalized its demands in the attire of a statute; if this alone were sufficient, the constitutional principle would be entirely abrogated by any Act of Congress”
CONCLUSION
For the foregoing reasons, the district court’s order is reversed insofar as it unconditionally commands the respondents to produce Beligratis’ cancelled checks and bank deposit slips, and the case is remanded to permit the government if it chooses to grant statutory -immunity with respect to the “testimonial” aspects of their production, and to allow the district court to fashion an appropriate protective order which will permit possible future use of these documents before the grand jury and at trial without reference to the circumstances of their production. 7 Circuit Rule 18 shall *1406 not apply. Each party shall bear its or his own costs.
Reversed and Remanded.
Notes
. The government does not cross-appeal from the district court’s denial of summons enforcement with respect to the appointment books.
. Indeed, despite lengthy discussion in the government’s brief concerning the continuing viability of Boyd's wholesale “private papers” exception in light of Fisher, we do not understand the respondents even to be arguing that Boyd affords a means of absolutely avoiding Fisher, but only that Boyd -type taxpayer documents meet the Fisher “implicit authentication” test. See Respondents’ Brief at 29 and Respondents’ Reply Brief at 7-8.
. 18 U.S.C. § 6003 provides:
(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 the privilege against self-incrimination, such order to become effective as provided in section 6002 of this part.
(b) A United States attorney may, with the approval of the Attorney General, the Deputy Attorney General, or any designated 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
*1403 (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.
18 U.S.C. § 6002 provides:
Whenever a witness refuses, on the basis of his privilege against self-incrimination, to testify or provide other information in a proceeding before or ancillary to
(1) a court or grand jury of the United States,
(2) an agency of the United States ...
******
and the person presiding over the proceeding communicates to the witness an order issued under this part, 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.
. The possibility of such a hybrid solution to the Fisher problem was first acknowledged by Justice Marshall in his Fisher concurrence:
If authentication that the document produced is the document demanded were the only testimony inherent in production, immunity would be a useful tool for obtaining written evidence. So long as the document obtained under an immunity grant could be authenticated through other sources, as would often be possible, reliance on the immunized testimony — the authentication — and its fruits would not be necessary, and the document could be introduced.
Respondents argue that this kind of bifurcated immunity with respect to the production but not the contents of the documents is not permissible under 18 U.S.C. § 6002. They argue that because the language of that provision requires that “no [immunized] testimony or other information compelled under the order ... may be used against the witness ... ”, 18 U.S.C. § 6002(3) (emphasis added), and “other information” is defined broadly at 18 U.S.C. § 6001(2) as “any book, paper, document, record, recording, or other material,” it must be the case that that “other information” whose use is forbidden would also include the contents of the documents. Such a reading, however, ignores the plain intent of the statute that the grant on immunity thereunder “is intended to be as broad as, but not broader than, the privilege against self-incrimination.” H.R. 1549, 91st Cong., 2d Sess., 1970 U.S.Code Cong. & Adm.News at 4017. Since Fisher held that the contents of these documents do not come under that privilege, the statute plainly does not extend to them. In addition, we note that Congress indicated that the statute’s “scope is intended to be comprehensive, including all information given as testimony but not orally.” H.R. 1549, supra; 1970 U.S.Code Cong. & Ad.News at 4017 (emphasis added). Since the contents of the documents here are not “testimony” under Fisher, they are not within the immunity created by the statute. This reading that only “testimonial” information is immunized by the statute does not, as respondents contend, nonsensically restrict the definition of “proceedings before an agency” in 18 U.S.C. § 6001 which includes “any proceeding ... with respect to which [the agency] is authorized too [sic] issue subpoenas and to take testimony or receive other information from witnesses under oath.” (emphasis added). This non-exclusive definition would still allow application of the statute to proceedings where the agency may also review non-testimonial documentary information.
. For example, it may well be that Beligratis’ cancelled checks would be self-authenticating under the “commercial paper” exception of Fed.R.Evid. 902(9).
We reserve the question, not presented here, whether in cases where the existence and location of the summoned documents is at issue and hence their production would be arguably “testimonial” with respect to these facts, the introduction of the contents of the documents would automatically be a breach of the statutory provision against “derivative use” of the information which would have to be immunized under the approach outlined here. As Justice Marshall suggested in his Fisher concurrence, in such cases of controverted existence and location, a “different result” might be warranted:
Under the Court’s theory, if the document is to be obtained the immunity grant must extend to the testimony that the document is presently in existence. Such a grant will effectively shield the contents of the document, for the contents are a direct fruit of the immunized testimony — that the document *1404 exists — and cannot usually be authenticated without reliance on that testimony.
. Nothing in
California Banker’s Association v. Schultz,
. In the narrow circumstances of this case, where neither existence nor possession, but only authentication, of the documents is contestable, we see no need for the imposition of a restriction on internal IRS use of the documents; in any event, that question was not raised here. However, if the district court per *1406 ceives that such use may have Fifth Amendment implications, it may consider imposing some additional protections for the taxpayer in its order in connection with such use.
