delivered the opinion of the Court.
This case arises out of the efforts of the Criminal Investigation Division of the Internal Revenue Service (IRS) to investigate the tax returns of L. Ron Hubbard, founder of the Church of Scientology (the Church), for the calendar years 1979 through 1983. We granted certiorari,
The second issue concerns the testimonial privilege for attorney-client communications and, more particularly, the generally recognized exception to that privilege for communications in furtherance of future illegal conduct — the so-called “crime-fraud” exception. The specific question presented is whether the applicability of the crime-fraud exception must be established by “independent evidence”
(i. e.,
without reference to the content of the contested communications themselves), or, alternatively, whether the applicability of that exception can be resolved by an
in camera
inspection of the allegedly privileged material.

We reject the “independent evidence” approach and hold that the district court, under

In the course of its investigation, the IRS sought access to 51 documents that had been filed with the Clerk of the Los Angeles County Superior Court in connection with a case entitled Church of Scientology of California v. Armstrong, No. C420 153. The Armstrong litigation involved, among other things, a charge by the Church that one of its former members, Gerald Armstrong, had obtained by unlawful means documentary materials relating to Church activities, including two tapes. Some of the documents sought by the IRS had been filed under seal.
The IRS, by its Special Agent Steven Petersell, served a summons upon the Clerk on October 24, 1984, pursuant to 26 U. S. C. §7603, demanding that he produce the 51 documents. 4 The tapes were among those listed. App. 33-38. On November 21, IRS agents were permitted to inspect and copy some of the summoned materials, including the tapes.
On November 27, the Church and Mary Sue Hubbard, who had intervened in
Armstrong,
secured a temporary restrain
On January 18, 1985, the IRS filed in the District Court a petition to enforce its summons. In addition to the tapes, the IRS sought 12 sealed documents the Clerk had refused to produce in response to the IRS summons. The Church and Mary Sue Hubbard intervened to oppose production of the tapes and the sealed documents. Respondents claimed that IRS was not seeking the documents in good faith, and objected on grounds of lack of relevance and attorney-client privilege.
Respondents asserted the privilege as a bar to disclosure of the tapes. The IRS argued, among other things, however, that the tapes fell within the crime-fraud exception to the attorney-client privilege, and urged the District Court to listen to the tapes in the course of making its privilege determination. In addition, the IRS submitted to the court two declarations by Agent Petersell. In the first, Petersell stated his grounds for believing that the tapes were relevant to the investigation. See Declaration in No. CV85-0440-HLH, ¶3 (March 8, 1985). In the second, Petersell offered a description of the tapes’ contents, based on information he received during several interviews. Appended to this declaration — over respondents’ objection — were partial transcripts of the tapes, which the IRS lawfully had obtained from a confidential source. See March 15, 1985, declaration
After oral argument and an evidentiary hearing, the District Court rejected respondents’ claim of bad faith. App. to Pet. for Cert. 27a. The court ordered production of 5 of the 12 documents, id., at 28a, and specified: “The documents delivered hereunder shall not be delivered to any other government agency by the IRS unless criminal tax prosecution is sought or an Order of Court is obtained.” Id., at 29a.
Turning to the tapes, the District Court ruled that respondents had demonstrated that they contain confidential attorney-client communications, that the privilege had not been waived, and that “[t]he ‘fraud-crime’ exception to the attorney-client privilege does not apply. The quoted excerpts tend to show or admit past fraud but there is no clear indication that future fraud or crime is being planned.”
Id.,
at 28a. On this basis, the court held that the Clerk “need not produce its copy of the tapes pursuant to the summons.”
Id.,
at 29a. The District Court denied the IRS’ motion for reconsideration, rejecting the IRS’ renewed request that the court listen to the tapes
in toto.
“While this was at one time discussed with counsel, thereafter Mr. Petersell’s declaration was submitted, and no one suggested that this
Respondents appealed to the Court of Appeals for the Ninth Circuit, and the IRS cross-appealed on two relevant grounds. First, the IRS claimed that the District Court abused its discretion by placing conditions on the IRS’ future use of the subpoenaed information. The Court of Appeals disagreed, holding: “A district court may, when appropriate, condition enforcement of a summons on the IRS’ agreeing to abide by disclosure restrictions.”
Second, the IRS contended that the District Court erred in rejecting the application of the crime-fraud exception to the tapes. In particular, the IRS argued that the District Court incorrectly held that the IRS had abandoned its request for
in camera
review of the tapes, and that the court should have listened to the tapes before ruling that the crime-fraud exception was inapplicable. Answering Brief for United States as Appellee in No. 85-6065, and Opening Brief for United States as Cross-Appellant in No. 85-6105 (CA9), pp. 48-49 (filed under seal). Respondents contended, in contrast, that the District Court erred in the opposite direction: they argued that it was error for the court to rely on the partial transcripts, because “[i]n this Circuit, a party cannot rely on the communications themselves — whether by listening to the tapes
or reviewing excerpts or transcripts of them
— to bear its burden to invoke the exception but must bear the burden by independent evidence. This is the clear and unambiguous holding of

This Court is evenly divided with respect to the issue of the power of a district court to place restrictions upon the dissemination by the IRS of information obtained through a § 7604 subpoena-enforcement action. We therefore affirm the judgment of the Court of Appeals insofar as it upheld the District Court’s conditional-enforcement order.
Questions of privilege that arise in the course of the adjudication of federal rights are “governed by the principles of the common law as they may be interpreted by the courts of the United States in the light of reason and experience.” Fed.

v.
United States,
The District Court and the Court of Appeals found that the tapes at issue in this case recorded attorney-client communications and that the privilege had not been waived when the tapes were inadvertently given to Armstrong.
A variety of questions may arise when a party raises the crime-fraud exception. The parties to this case have not been in complete agreement as to which of these questions are presented here. In an effort to clarify the matter, we observe, first, that we need not decide the quantum of proof necessary ultimately to establish the applicability of the crime-fraud exception. Cf.
Clark,
A
We consider first the question whether a district court may ever honor the request of the party opposing the privilege to conduct an in camera review of allegedly privileged communications to determine whether those communications fall within the crime-fraud exception. We conclude that no express provision of the Federal Rules of Evidence bars such use of in camera review, and that it would be unwise to prohibit it in all instances as a matter of federal common law. 9

At first blush, two provisions of the Federal Rules of Evidence would appear to be relevant. Rule 104(a) provides: “Preliminary questions concerning the qualification of a person to be a witness,
the existence of a privilege,
or the admissibility of evidence shall be determined by the court .... In making its determination it is not bound by the rules of evidence
except those with respect to privileges. ”
(Emphasis added.) Rule 1101(c) provides: “The rule with respect to
Even those scholars who support this reading of Rule 104(a) acknowledge that it leads to an absurd result.
“Because the judge must honor claims of privilege made during his preliminary fact determinations, many exceptions to the rules of privilege will become ‘dead letters,’ since the preliminary facts that give rise to these exceptions can never be proved. For example, an exception to the attorney-client privilege provides that there is no privilege if the communication was made to enable anyone to commit a crime or fraud. There is virtually no way in which the exception can ever be proved, save by compelling disclosure of the contents of the communication; Rule 104(a) provides that this cannot be done.” 21 C. Wright & K. Graham, Federal Practice & Procedure: Evidence §5055, p. 276 (1977) (footnote omitted).
We find this Draconian interpretation of Rule 104(a) inconsistent with the Rule’s plain language. The Rule does not provide by its terms that all materials as to which a “clai[m] of privilege” is made must be excluded from consideration. In that critical respect, the language of Rule 104(a) is markedly different from the comparable California evidence rule, which provides that “the presiding officer may not require disclosure of information
claimed, to be privileged
under this division in order to rule on the claim of privilege.” Cal. Evid. Code Ann. § 915(a) (West Supp. 1989) (emphasis
Nor does it make sense to us to assume, as respondents have throughout this litigation, that once the attorney-client nature of the contested communications is established, those communications must be treated as
presumptively
privileged for evidentiary purposes until the privilege is “defeated” or “stripped away” by proof that the communications took place in the course of planning future crime or fraud. See Brief for Respondents 15 (asserting that respondents had “established their entitlement to the privilege,” and that the communications had been “determined to be privileged,” before the crime-fraud question was resolved). Although some language in
Clark
might be read as supporting this view, see

Having determined that Rule 104(a) does not prohibit the in camera review sought by the IRS, we must address the question as a matter of the federal common law of privileges. See Rule 501. We conclude that a complete prohibition against opponents’ use of m camera review to establish the applicability of the crime-fraud exception is inconsistent with the policies underlying the privilege.
We begin our analysis by recognizing that disclosure of allegedly privileged materials to the district court for purposes of determining the merits of a claim of privilege does not have the legal effect of terminating the privilege. Indeed, this
Once it is clear that in camera review does not destroy the privileged nature of the contested communications, the question of the propriety of that review turns on whether the policies underlying the privilege and its exceptions are better fostered by permitting such review or by prohibiting it. In our view, the costs of imposing an absolute bar to consideration of the communications in camera for purpose of establishing the crime-fraud exception are intolerably high.
“No matter how light the burden of proof which confronts the party claiming the exception, there are many blatant abuses of privilege which cannot be substantiated by extrinsic evidence. This is particularly true . . . of. . . situations in which an alleged illegal proposal is made in the context of a relationship which has an apparent legitimate end.” Note, The Future Crime or Tort Exception to Communications Privileges, 77 Harv. L. Rev. 730, 737 (1964). A

rule that the communications in question may never be considered creates, we feel, too great an impediment to the proper functioning of the adversary process. See generally 2 D. Louisell & C. Mueller, Federal Evidence § 213, pp. 828-829 (1985); 2 J. Weinstein & M. Berger, Weinstein’s Evi

We turn to the question whether in camera review at the behest of the party asserting the crime-fraud exception is always permissible, or, in contrast, whether the party seeking in camera review must make some threshold showing that such review is appropriate. In addressing this question, we attend to the detrimental effect, if any, of in camera review on the policies underlying the privilege and on the orderly administration of justice in our courts. We conclude that some such showing must be made.
Our endorsement of the practice of testing proponents’ privilege claims through
in camera
review of the allegedly privileged documents has not been without reservation. This Court noted in

proceedings. See,

Caldwell
v.
District Court,
Once that showing is made, the decision whether to engage in in camera review rests in the sound discretion of the district court. The court should make that decision in light of the facts and circumstances of the particular case, including, among other things, the volume of materials the district court has been asked to review, the relative importance to the case of the alleged privileged information, and the likelihood that the evidence produced through in camera review, together with other available evidence then before the court, will establish that the crime-fraud exception does apply. The district court is also free to defer its in camera review if it concludes that additional evidence in support of the crime-fraud exception may be available that is not allegedly privileged, and that production of the additional evidence will not unduly disrupt or delay the proceedings.
The question remains as to what kind of evidence a district court may consider in determining whether it has the discretion to undertake an in camera review of an allegedly privileged communication at the behest of the party opposing the privilege. Here, the issue is whether the partial transcripts may be used by the IRS in support of its request for in camera review of the tapes.
The answer to that question, in the first instance, must be found in Rule 104(a), which establishes that materials that have been determined to be privileged may not be considered in making the preliminary determination of the existence of a privilege. Neither the District Court nor the Court of Appeals made factual findings as to the privileged nature of the partial transcripts, 11 so we cannot determine on this record whether Rule 104(a) would bar their consideration.
Assuming for the moment, however, that no rule of privilege bars the IRS’ use of the partial transcripts, we fail to see what purpose would be served by excluding the transcripts from the District Court’s consideration. There can be little doubt that partial transcripts, or other evidence directly but incompletely reflecting the content of the contested communications, generally will be strong evidence of the subject matter of the communications themselves. Permitting district courts to consider this type of evidence would aid them substantially in rapidly and reliably determining whether in camera review is appropriate.
D
In sum, we conclude that a rigid independent evidence requirement does not comport with “reason and experience,” Fed. Rule Evid. 501, and we decline to adopt it as part of the developing federal common law of evidentiary privileges. We hold that
in camera
review may be used to determine whether allegedly privileged attorney-client communications fall within the crime-fraud exception. We further hold, however, that before a district court may engage in
in camera
review at the request of the party opposing the privilege, that party must present evidence sufficient to support a reasonable belief that
in camera
review may yield evidence that
Because the Court of Appeals employed a rigid independent-evidence requirement which categorically excluded the partial transcripts and the tapes themselves from consideration, we vacate its judgment on this issue and remand the case for further proceedings consistent with this opinion. On remand, the Court of Appeals should consider whether the District Court’s refusal to listen to the tapes in toto was justified by the manner in which the IRS presented and preserved its request for in camera review. 13 In the event the Court of Appeals holds that the IRS’ demand for review was properly preserved, the Court of Appeals should then determine, or remand the case to the District Court to determine in the first instance, whether the IRS has presented a sufficient evidentiary basis for in camera review, and whether, if so, it is appropriate for the District Court, in its discretion, to grant such review.
It is so ordered.

Shewfelt,
Respondents suggest that this case is now moot, because L. Ron Hubbard died January 24,1986, thus foreclosing any further criminal investigation of him, and because the IRS civil audit of Mr. Hubbard for the relevant tax years was terminated as a “‘closed case.’” Brief in Opposition 8-10. The IRS disagrees, largely because the civil tax audit has not been terminated, and its result could affect the liability of Mr. Hubbard’s estate. We are satisfied that a live controversy remains.
The current Clerk of the Superior Court, Frank S. Zolin, is a named respondent in this case, but did not participate in briefing or argument before the Court of Appeals or before this Court. We use the term “respondents” to refer to Mary Sue Hubbard and the Church, the only active respondents in this Court.
The IRS denied that the transcripts were made using tapes obtained from the Superior Court or from any other illicit source. Agent Petersell declared: “The partial transcripts were not prepared by the United States from the tapes in the custody of the Superior Court for Los Angeles County, California, nor from copies of the tape now in the custody of the Clerk of this Court. The transcripts were obtained from a confidential source by another Special Agent prior to the issuance of this summons. The source was not a party to Church of Scientology v. Armstrong, No. 410153, nor an attorney for any party in that proceeding.” See Declaration of Agent Petersell in No. CV85-0440-HLH (Tx) (March 21, 1985). As the District Court made no finding of illegality, we assume for present purposes that the transcripts were legally obtained.
See also Hazard, An Historical Perspective on the Attorney-Client Privilege, 66 Calif. L. Rev. 1061 (1978); Developments in the Law—Privileged Communications, 98 Harv. L. Rev. 1450, 1455-1458 (1985).
We note, however, that this Court’s use in
Clark
v.
United States,
In addition, the facts of this case also suggest the question whether the partial transcripts the IRS possessed may be used by it in meeting its ultimate burden. It is by no means clear that the Government has presented that question for this Court’s review. The Government noted in its petition for certiorari that the Court of Appeals had not considered the partial transcripts in making its determination that the IRS had failed to establish the applicability of the crime-fraud exception. See Pet. for Cert. 7-8. The question presented for review, however, relates solely to in camera review, as does the relevant discussion in the petition. See id., at 20-23.
The question whether the partial transcripts may be used in meeting the IRS’ ultimate burden of demonstrating the applicability of the crime-fraud exception is fairly included within the question presented, however, and we therefore address it. See this Court's Rule 21.1(a). The answer to the question would follow inexorably from our discussion in any event.
There is some ambiguity as to whether the Court of Appeals squarely barred all use of in camera review for these purposes, although that is the fairest reading of the court’s opinion. Respondents at times appear to advocate that position, see Brief in Opposition 19-21, but at times suggest otherwise, see Brief for Respondents 13; see also Reply Brief for United States 15. The ambiguity in respondents’ position is perhaps due to the fact that they accept the premise that in camera review is permitted under Circuit precedent in different circumstances from those at issue in this case — i. e., where the proponent of the privilege seeks in camera review to demonstrate the applicability of the privilege in the first instance, see Brief for Respondents 14, or when the proponent requests in camera review to ensure that an order requiring production of some materials held not to be privileged does not inadvertently yield privileged information, see id., at 20-21.
A good example of the effect of the California rule is provided by the record in this case. While the disputed matters were being briefed in Federal District Court, the State Superior Court held a hearing on a motion by Government attorneys seeking access to materials in the Armstrong case for ongoing litigation in Washington, D. C. The transcript of the hearing was made part of the record before the District Court in this case. Regarding the tapes, the Government argued to the Superior Court that the attorney-client conversations on the tapes reflect the planning or commission of a crime or fraud. Tr. of Hearing of February 11, 1985, in No. C420 153 (Super. Ct. Cal), p. 52. That claim was supported by several declarations and other extrinsic evidence. The Government noted, however, that “the tape recordings themselves would ... be the best evidence of exactly what was going on.” Id., at 53. The intervenors stressed that, as a matter of California law, “you can’t show the tapes are not privileged by the contents.” Id., at 58; see also id., at 68. The Superior Court acknowledged the premise that “you can’t look at the conversation itself to make [the crime-fraud] determination,” id., at 74, and concluded that the extrinsic evidence was not sufficient to make out a prima facie case that the crime-fraud exception applies, id., at 75-76.
There are no findings as to whether respondents themselves would be privileged to resist a demand that
they
produce the partial transcripts. Nor has there been any legal and factual exploration of whether respondents may claim privilege as a bar to the IRS’ use of the copy of the transcripts it lawfully obtained from a third party. See,
e. g.,
Developments in the Law — Privileged Communications,
In addition, we conclude that evidence that is not “independent” of the contents of allegedly privileged communications —like the partial transcripts in this case — may be used not only in the pursuit of in camera review, but also may provide the evidentiary basis for the ultimate showing that the crime-fraud exception applies. We see little to distinguish these two uses: in both circumstances, if the evidence has not itself been determined to be privileged, its exclusion does not serve the policies which underlie the attorney-client privilege. See generally Note, The Future Crime or Tort Exception to Communications Privileges, 77 Harv. L. Rev. 730, 737 (1964).
The Court of Appeals also will have the opportunity to review the partial transcripts, and to determine whether, even without in camera review of the tapes, the IRS presented sufficient evidence to establish that the tapes are within the crime-fraud exception.
