OPINION OF THE COURT
In this аppeal, we are faced with an issue of first impression for this court, whether the target of a grand jury investigation whose attorney has been subpoenaed to give testimony and provide documents to the grand jury that would ordinarily be protected by attorney-client privilege is entitled to review the government’s ex parte affidavit upon which the District Court relied in deciding that the crime-fraud exceptiоn was applicable.
In order to preserve the confidentiality of the proceedings, we will refer to the dramatis personae as the client or the target (the target of the investigation) and the attorney (who is the witness under subpoena). We will also not identify the documents that were subpoenaed, as the legal issue before us is not dependent on the particular documents. We will assume *215 arguendo that those documents ordinarily would be privileged.
I.
There is an ongoing extensive federal grand jury investigation into the client’s activities in connection with potential violations of the Internal Revenue Code and 18 U.S.C. §§ 371, 1341 and 1951. We were advised at the oral argument that the grand jury investigation has been underway for two years and that numerous witnesses have testified and numerous documеnts have been produced.
The attorney who was subpoenaed has represented the target for more than a year in connection with the criminal investigation. The government subpoenaed the attorney “as a witness in the investigation” of his client. The attorney moved to quash the grand jury subpoena, asserting that testimony and production of documents concerning the subject mattеr specified in the subpoena would result in disclosure of privileged attorney-client communications and work product material and would violate his client’s Sixth Amendment right to counsel because the attorney’s testimony would disqualify him from representing the client-target. The client was given permission to intervene and asserted the same arguments. In response, the government, which had earlier рrovided the attorney with a Schofield affidavit minimally disclosing the purpose of the grand jury investigation, submitted a second Schofield affidavit, this one ex 'parte, to establish the applicability here of the crime-fraud exception to the attorney-client privilege. The affidavit details the grand jury investigation, and includes excerpts of testimony and documents obtained during the course of the investigation.
On May 4, 2000, the District Court held a closed hearing on the motion to quash. Counsel for the subpoenaed attorney and his client argued that without recourse to the ex parte affidavit, they could not effectively rebut the government’s assertion of the crime-fraud exception, consequently depriving the client of his due process right to be heard. On May 17, 2000, the District Court issued a Memorandum and Order denying the motion to quash and directing the attorney to testify. The сourt found that “the government’s Scho-field affidavit adequately sets forth the purpose of the grand jury’s investigation and that [the attorney’s] testimony would be relevant to the investigation.” The court further stated “there is no indication that [the attorney’s] testimony is sought for an improper purpose. The Court is also convinced that disclosure of the Scho-field affidavit at this time would compromise the secrecy of the grаnd jury.” Finally, and most pertinent here, the court held that “the Schofield affidavit adequately sets forth the basis for invocation of the crime-fraud exception .... ”
The client appeals. He argues that the District Court’s procedure of relying on an
ex parte
affidavit to determine that the crime-fraud exception applied was inconsistent with this court’s decision in
Haines v. Liggett Group Inc.,
II.
A.
Central to our review of the District Court’s decision is an understanding of the *216 role of the grand jury in the administration of our criminal justice system. The Supreme Court has commented:
The institution of the grand jury is deeply rooted in Anglo-American history. In England, the grand jury served for centuries both as a body of accusers sworn to discover and present for trial persons suspected of criminal wrongdoing and as a protector of citizens against arbitrary and oppressive governmental action. In this country the Founders thought the grand jury so essential to basic liberties that they provided in the Fifth Amendment that federal prosecution for serious crimes can only be instituted by a presentment or indictment of a Grand Jury. The grand jury’s historic functions survive to this day. Its responsibilities continue to include both the determination whether there is probable cause to believe a crime has been committed and the protection of citizens against unfounded criminal prosecutions.
United States v. Calandra,
A grand jury proceeding is not an adversary hearing where guilt or innocence is adjudicated but an
ex parte
investigation to determine if there is probable cause to believe a crime has been committed. The grand jury deliberates in secret and acts “independently of either prosecuting attorney or judge-”
United States v. Dionisio,
To prevent abuse of this process, this court has required the government to justify a grand jury subpoena by making “some preliminary showing by affidavit that each item [being subpoenaed] is at least relevant to an investigation being conducted by the grand jury and properly within its jurisdiction, and is not sought primarily for another purpose.”
In re Grand Jury Proceedings (Schofield),
The issue came before us recently in
In re the Grand Jury Empaneling of the Special Grand Jury,
The proceedings in this case followed a similar pattern. The government provided the subpoenaed attorney with a Schofield affidavit containing the limited disclosure required. The attorney filed an affidavit invoking the attorney-client privilege and a motion to quash the subpoena. The client intervened. The government then filed a *217 supplemental ex parte affidavit, i.e., a second Schofield affidavit in which it asserted the crime-fraud exception to that privilege. Based on that ex parte affidavit, the District Court ruled the crime-fraud exception was applicable.
The Appellant recognizes and does not challenge the general use of ex parte Scho-field affidavits. Instead, he argues that this case differs from our earlier decisions because the information being subpoenaed is protected by attorney-client privilege. He contends that it is unfair and inequitable for the District Court to have relied solely on an ex parte affidavit to decide that the crime-fraud exception applied when he was unable to rebut the government’s allegations. This court has not previously considered the use of an ex parte affidavit when the subpoenaed witness asserts the attorney-client privilege.
B.
The Supreme Court has described the attorney-client privilege as “thе oldest of the privileges for confidential communications known to the common law.”
Upjohn Co. v. United States,
Although the underlying rationale for the privilege has changed over time, courts long have viewed its central concern as one “to encourage full and frank communicatiоn between attorneys and their clients and thereby promote broader public interests in the observance of law and administration of justice.” That purpose, of course, requires that clients be free to “make full disclosure to their attorneys” of past wrongdoings, in order that the client may obtain “the aid of persons having knowledge of the law and skilled in its practice.”
The attorney-client privilege is not without its costs. “Since the privilege has the effect of withholding relevant information from the factfinder, it applies only where necessary to achieve its purpose.” The attorney-client privilege must necessarily protect the confidences of wrongdoers, but the reason for that protection — the centrality of open client and attorney communication to the proper functioning of our adversary system of justice — “ceases to operate at a certain point, namely, where the desired advice refers not to prior wrongdoing, but to future wrongdoing.” It is the purpose of the crime-fraud exception to the attorney-client privilege to assure that the “seal of secrecy” between lawyer and client does not extend to communicаtions “made for the purpose of getting advice for the commission of a fraud” or crime.
Id.
at 562-63,
This court has recognized the importance of the attorney-client privilege and has emphasized that the crime-fraud exception applies only when the legal advice “gives direction for the commission of future fraud or crime.”
Haines v. Liggett Group Inc.,
The District Court agreed that communications between the attorney-witness and his client-target would “normally be protected by the attorney-client privi *218 lege,” but held that the crime-fraud exception applied to the communications in this case. In appealing the District Court’s order, Appellant argues that the court erred in failing to apply the reasoning of Haines when it denied him the right to examine the ex parte affidavit. We believe Haines does not compel a different result here.
In Haines, the plaintiff, who was suing the tobacco industry for wrongful death, sought discovery of certain documents under the crime-fraud exception to the attorney-client privilege. The district court held the exception applied and directed discovery. The tobacco companies petitioned for a writ of mandamus, which this court granted. We held that the appropriate procedure for determining the applicability of the crime-fraud exception in the context of civil litigation requires that, after the party seeking the documents makes a prima facie showing that the exception applies, the party invoking the attorney-client privilege be given an opportunity to rebut. See id. at 97. We stated that when a district court weighs the evidence to determine the applicability of the crime-fraud exception to privilege, the party invoking the privilege has the “absolute right to be heard by testimony and argument.” Id. at 97.
Appellant acknowledges that we made explicit in the Haines opinion that the discussion was confined to the civil context and that we intimated “no view as to whether the same procedures should be used in the grand jury context.” Id. at 97 n. 8. Nevertheless, Appellant argues that if we do not extend the Haines holding to the grand jury investigation in this case, “the Haines rationale would be rendered meaningless.”
This case differs from
Haines
not only because
Haines
was a civil case and this is a criminal one but, even more important, because
Haines
involved adversarial proceedings whereas grand jury proceedings are investigative, and the rules of the game are different.
See, e.g., Calandra,
One of the most significant, if not the most significant, differences stemming from the investigative role of the grand jury is the importance of secrecy, particularly when an investigation is on-going.
See generally
Fed.R.Crim.P. 6(e)(2) (prohibiting disclosure оf matters occurring before the grand jury);
see also In re the Grand Jury Empaneling,
(1) To prevent the escape of those whose indictment may be contemplated; (2) to insure the utmost freedom to the grand jury in its deliberations, and to prevent persons subject to indictment or their friends from importuning the grand jurors; (3) to prevent subornation of perjury or tampering with the witnesses who may testify before [the] grand jury and later appear at the trial of those indicted by it; (4) to encourage free and untrammeled disclosures by persons who have information with respect to the commission of crimes; (5) to protect [an] innocent accused who is exonerated from disclosure of the fact that he has been under investigation, and from the exрense of standing trial where there was no probability of guilt.
United States v. John Doe, Inc. I,
*219 Given the acknowledged need fоr secrecy in grand jury proceedings, we reject Appellant’s argument that the “unique facts and circumstances in this case,” including the length of time the investigation has been pending and the fact that the nature of the investigation has already been made public in several contexts, required the District Court to order disclosure of the government’s ex parte affidavit. As we have stated, the ex parte affidavit includes excerpts of witness testimony and documents obtained during the investigation, which is ongoing. We conclude that the District Court did not abuse its discretion in denying Appellant and/or his attorney access to this information to protect grand jury secrecy.
Our decision is in accord with those of the other federal courts of appeal that have already addressed this precise issue and rejected due process clаims made under virtually identical facts. For example, in
In re Grand Jury Subpoenas,
Similarly, when faced with the argument by grand jury targets that their due process rights were violated by their inability to inspect and rebut the
ex parte
affidavit submitted by the government in support of its invocation of the crime-fraud exception to the attorney-client privilege, the Second Circuit held that they were properly denied access.
In re John Doe, Inc.,
We today join the ranks of our sister circuits in holding thаt it is within the district courts’ discretion, and not vio-lative of due process, to rely on an ex parte government affidavit to determine that the crime-fraud exception applies and thus compel a target-client’s subpoenaed attorney to testify before the grand jury.
We do so confident that the district courts will vigorously test the factual and legal bases for any subpoena, and a court which questions the sufficiency of the affidavits has available various avenues of inquiry, among them discovery,
in camera
inspection, additional affidavits and a hearing.
See In re Grand Jury Proceedings (Schofield II),
Finally, although Apрellant has alluded to a denial of his Sixth Amendment right to counsel in his statement of the issues for review, he does not specifically address this claim, cite any authority, or
*220
develop an argument in its support. Nonetheless, we note that
In
re
Special September 1978 Grand Jury (II),
the court, after rejecting a due process argument and sustaining a grand jury subpoena issued upon an attorney on the basis of the crime-fraud exception, stated that appellants “cannot claim that their rights to the effective assistance of counsel were infringed because that right does not attach until criminal proceedings with a known defendant have been instituted.”
Also, the Court of Appeals for the Second Circuit addressed this preсise issue in a factually similar case, rejecting the Sixth Amendment violation claim. In
In re Grand Jury Subpoena Served Upon Doe,
Before disqualification can even be contemplated, the attorney’s testimony must incriminate his client; the grand jury must indict; the government must go forward with the prosecution of the indictment; and ultimately, the attorney must be advised that he will be called as a trial witness against his client. As a court, we decline to speculаte that all those events will occur. Apparently [appellant] ignores the possibility that his attorney’s grand jury testimony may be exculpatory or neutral, or that the government may decide not to use such information at trial, or that the information may be presented at trial in such a way that the attorney can avoid testifying, or that the trial judge may rule in limine that the information is not admissible, perhаps because its probative force does not justify a resulting disqualification of counsel. Disqualification of counsel is not inevitable.
Id. at 245.
The District Court here considered and rejected the Appellant’s argument that requiring his attorney to testify before the grand jury concerning their attorney-client communication will disqualify the attorney as counsel in connection with the investigation and possible future charges, effectively denying the client his right to choose counsel.
As the District Court held in its opinion, “it is only speculation that [the attorney] may be disqualified from representing [the client] if he testifies before the grand jury ....” We agree and reject the claim of a Sixth Amendment violation.
III.
For the reasons set forth, we will affirm the District Court’s order denying Appellant’s motion as an intervenor to quash the grand jury subpoena issued upon his attorney.
