Opinion
CORRIGAN, J.
Here we hold that California courts do not have a broad inherent power to order disclosure of grand jury materials to private litigants. In Daily Journal Corp. v. Superior Court (1999) 20 Cal.4th 1117 [86 Cal.Rptr.2d 623, 979 P.2d 982] (Daily Journal), this court ruled that “the superior court’s powers to disclose grand jury testimony are only those which the Legislature has deemed appropriate.” (Id. at p. 1128.) “[I]f superior courts could disclose materials based only on their inherent powers, the statutory rules governing disclosure of grand jury testimony would be swallowed up in that large exception.” (Ibid.)
In this case, the Court of Appeal decided that courts have inherent power to order disclosure of grand jury materials to a private litigant, in the interests of justice. The court distinguished Daily Journal on the basis that it involved disclosure to the public. We reverse. The Legislature has authorized [222]*222limited disclosure of grand jury materials to private parties, and the Court of Appeal’s holding creates a broad exception that would swallow the statutory rules, just as in Daily Journal.
The Court of Appeal also held that no statute authorized the disclosure of grand jury materials to petitioner Thomas Lee Goldstein. However, Penal Code section 924.2 does permit the disclosure of grand jury testimony to determine whether it is consistent with a witness’s subsequent testimony.1 Goldstein may be able to obtain limited releases of grand jury transcripts under this provision.
BACKGROUND
In 1979 Goldstein was an engineering student and Marine Corps veteran with no criminal history. He became a murder suspect after an eyewitness to an unrelated shooting saw the gunman enter Goldstein’s apartment building. No witness or forensic evidence connected Goldstein with the murder victim, but Long Beach police detectives showed Goldstein’s photograph, among others, to Loran Campbell, an eyewitness to the homicide. Campbell did not recognize anyone in the photo lineup, and Goldstein did not match Campbell’s description of the suspect. However, a detective asked if Goldstein could have been the person Campbell saw running from the scene. Campbell said it was possible, though he was not certain.
Goldstein was arrested and placed in a jail cell with Edward Floyd Fink, a heroin addict and convicted felon. At Goldstein’s trial, Fink testified that Goldstein said he was in jail because he shot a man in a dispute over money. Fink claimed he received no benefit as a result of his testimony. Goldstein was convicted of murder in 1980. In 1988, the Los Angeles County Grand Jury began an investigation into the use of jailhouse informants. In 1990, it issued a public report concluding that misuse of jailhouse informants had been pervasive over the preceding 10 years. The grand jury found that the Los Angeles County District Attorney’s Office had demonstrated a “deliberate and informed declination to take the action necessary to curtail the misuse of jailhouse informant testimony.” Among other deficiencies, it had failed to create a centralized index of potential impeachment information about informants, including any benefit they received for their testimony and their history of cooperation with law enforcement.
The Superior Court of Los Angeles County ordered that “material accumulated and used by the 1988-89 Grand Jury and the 1989-90 Grand Jury in their investigations of the jailhouse informants is to be kept secure by the [223]*223court. HO The material is not to be viewed, inspected or copied except by order of the Presiding Judge, Assistant Presiding Judge, or the Supervising Judge of the Criminal Division.”
After the grand jury released its report, Goldstein sought a writ of habeas corpus in federal court. At an evidentiary hearing in August 2002, Loran Campbell recanted his identification of Goldstein. Campbell admitted he had been overanxious to help the police. He had identified Goldstein based on what the police told him and his desire to be a good citizen, not on his observations on the night of the murder. Goldstein also presented evidence that Fink had received benefits for cooperating with law enforcement. The magistrate found Campbell credible, and stated: “It is readily apparent to this Court that Fink fits the profile of the dishonest jailhouse informant that the Grand Jury Report found to be highly active in Los Angeles County at the time of [Goldstein’s] conviction.” Goldstein’s petition was granted. He was released from custody in April of 2003, after serving 24 years in prison.
In November 2004, Goldstein filed suit in federal court against the City of Long Beach, four Long Beach police detectives, the County of Los Angeles, and two members of the Los Angeles County District Attorney’s Office. He stated causes of action under the federal civil rights statute, 42 United States Code section 1983, including claims that the defendants wrongfully obtained his conviction based on their pattern and practice of misusing the testimony of jailhouse informants.
Goldstein first sought access to the grand jury material held by the court in a February 2006 letter to the Presiding Judge of the Los Angeles County Superior Court and the supervising judge of the court’s criminal division. Counsel for the superior court replied that the material would not be disclosed because no statutory exception to the rule of grand jury confidentiality appeared to apply. When Goldstein’s counsel said he was willing to abide by a protective order limiting use of the material to the civil rights case, the court’s counsel evidently indicated that a subpoena would be needed to release the grand jury material.
In July 2006, Goldstein served a federal court subpoena on the superior court requesting production of the grand jury materials. The court’s counsel objected, asking Goldstein to withdraw the subpoena and seek access under the 1990 order of the superior court by “appropriate motion before the Presiding Judge, the Assisting Presiding Judge, or the Supervising Judge of the Criminal Division of the Superior Court.” Goldstein complied with this request. In September 2006 he filed a motion seeking access to the grand jury materials under sections 924.2, 929, and 939.1.
[224]*224Counsel for the County of Los Angeles responded to the motion on behalf of the grand jury in January 2007. County counsel contended the controlling authority was Socialist Workers Party v. Grubisic (7th Cir. 1980) 619 F.2d 641. Grubisic requires a party seeking disclosure in a federal action to first submit a request to the state court that supervised the grand jury, to determine if there is a continuing need for secrecy. If not, the grand jury materials may be disclosed. If the state court decides the materials should remain secret, the federal court then determines whether the need for disclosure outweighs the need for secrecy, under the test provided in Douglas Oil Co. v. Petrol Stops Northwest (1979) 441 U.S. 211, 222 [60 L.Ed.2d 156, 99 S.Ct. 1667] (Douglas Oil). (Grubisic, supra, at p. 644.) County counsel suggested that the court appoint a special master to review the grand jury materials and recommend which records might be disclosed. Goldstein disputed the need for secrecy and opposed the appointment of a special master, contending it would only cause unnecessary delay.
In March 2007, the court heard argument on the motion and denied Goldstein’s request, concluding that the statutes on which he relied did not authorize disclosure of the grand jury materials.2 Goldstein challenged this ruling by seeking a writ of mandate. He contended disclosure was permitted under sections 924.2 and 929.3 The grand jury and the County responded that the statutes did not authorize disclosure to Goldstein. The grand jury, however, conceded that the federal court would be able to compel disclosure if the circumstances justified it, and faulted Goldstein for failing to pursue his remedy by way of federal subpoena.
[225]*225The Court of Appeal granted Goldstein’s petition and directed the superior court to reconsider his motion to determine whether disclosure was required in the interests of justice, under the Douglas Oil test. The court rejected Goldstein’s statutory claims. However, though no party had briefed the issue, it decided that California law permitted the superior court to exercise its inherent authority to prevent injustice in a particular case. The court relied on a quotation from a treatise in Ex Parte Sontag (1884) 64 Cal. 525, 526 [2 P. 402] (Sontag), and decided that Daily Journal did not apply because it concerned only public disclosure of grand jury proceedings. We granted review.
DISCUSSION
We briefly outline the positions taken by the parties. The grand jury and the County dispute the notion that California courts have inherent authority to order disclosure of grand jury materials, and maintain that no statute supports Goldstein’s request for disclosure.4 The grand jury continues to contend that Goldstein might have obtained disclosure by pursuing a federal court subpoena.5 In its reply brief, however, the grand jury concedes it is unclear whether the federal court could compel disclosure if the state court were to rule that the grand jury materials should remain confidential.6
Goldstein claims the Court of Appeal’s decision does not conflict with Daily Journal, and is consistent with the statutory scheme governing the release of grand jury materials. Alternatively, he argues that even if courts lack inherent power to order disclosure to private litigants, statutory authority for the discovery he seeks is found in sections 924.2 and 929.
[226]*226The law regarding disclosure of evidentiary materials gathered by a grand jury was comprehensively analyzed in two decisions by this court, Daily Journal, supra, 20 Cal.4th 1117, and McClatchy Newspapers v. Superior Court (1988) 44 Cal.3d 1162 [245 Cal.Rptr. 774, 751 P.2d 1329] (McClatchy). In McClatchy, we noted: “The California grand jury has three basic functions: to weigh criminal charges and determine whether indictments should be returned (§ 917); to weigh allegations of misconduct against public officials and determine whether to present formal accusations requesting their removal from office (§ 922; see Gov. Code, § 3060 et seq.); and to act as the public’s ‘watchdog’ by investigating and reporting upon the affairs of local government (e.g., §§ 919, 925 et seq.). Of these functions, the watchdog role is by far the one most often played by the modem grand jury in California. [Citations.]” (McClatchy; supra, 44 Cal.3d at p. 1170.)
McClatchy arose from a decision by a civil grand jury to make public the evidentiary materials it gathered during an investigation into Fresno County’s award of a computer service contract. The superior court struck the portion of the grand jury report announcing the intended disclosure, and sealed the evidentiary materials. (McClatchy, supra, 44 Cal.3d at pp. 1167-1168.) The Court of Appeal ordered release of the materials, reasoning that a court may refuse to file a grand jury report only when the grand jury has violated an explicit statutory limitation. (Id. at p. 1169.) This court disagreed, holding that the superior court acted properly to ensure the grand jury did not exceed its statutory authority. (Id. at p. 1184.)
Reviewing the statutes governing the functions of the grand jury, we concluded that the Legislature intended to incorporate the common law tradition of preserving the secrecy of grand jury proceedings. (McClatchy, supra, 44 Cal.3d at pp. 1172-1174.) The interests underlying that tradition were identified in Douglas Oil: “First, if preindictment proceedings were made public, many prospective witnesses would be hesitant to come forward voluntarily, knowing that those against whom they testify would be aware of that testimony. Moreover, witnesses who appeared before the grand jury would be less likely to testify fully and frankly, as they would be open to retribution as well as to inducements. There also would be the risk that those about to be indicted would flee, or would try to influence individual grand jurors to vote against indictment. Finally, by preserving the secrecy of the proceedings, we assure that persons who are accused but exonerated by the grand jury will not be held up to public ridicule.” (Douglas Oil, supra, 441 U.S. at p. 219, fn. omitted; see McClatchy, at pp. 1174-1175.)
The McClatchy court observed that “the encouragement of candid testimony and the protection of witnesses and their reputations are best achieved when secrecy is maintained even after the conclusion of a grand jury [227]*227investigation.” (McClatchy, supra, 44 Cal.3d at p. 1175.) It also emphasized that secrecy is essential for both the indictment and “watchdog” functions of the grand jury. “The importance of secrecy is well established in the context of the grand jury’s criminal indictment function. By the same token, when the grand jury conducts a watchdog investigation of local government operations as in the instant case, secrecy appears equally vital. Compared with indictment proceedings, the efficacy and credibility of watchdog investigations no less require that witnesses testify without fear of reproach by their peers or their superiors. Though the watchdog investigation and report serve a different social purpose than the criminal indictment, eliciting candid testimony is obviously critical to both functions of the grand jury.” (Ibid.) “Secrecy also serves to protect the reputations of those who may be unjustly accused during the course of a watchdog investigation.” (Id. at p. 1176.)
“Recognizing the important purposes served by grand jury secrecy, the Legislature has enumerated only three situations in which disclosure of raw evidentiary materials is permitted. First, by court order the testimony of a witness may be disclosed to determine whether it is consistent with testimony given before the court or when relevant to a charge of perjury. (§ 924.2; [citation].) Secondly, section 938.1, subdivision (b), provides that when an indictment is returned, transcripts of testimony taken before the grand jury are to be delivered to the defendant and thereafter filed for public access. [Citation], [f] And finally, evidentiary materials gathered by one grand jury may be disclosed to a succeeding grand jury. (§ 924.4 . . . .) Section 924.4 represents the grand jury’s only statutory authority to undertake disclosure of its evidentiary materials on its own initiative.”7 (McClatchy, supra, 44 Cal.3d at p. 1178, fns. omitted.)
In McClatchy, we rejected the idea that the grand jury has intrinsic power to disclose evidentiary material to the public. “Broad though they are, the grand jury’s powers are only those which the Legislature has deemed appropriate.” (McClatchy, supra, 44 Cal.3d at p. 1179.) We noted several statutes indicating that the Legislature intentionally withheld from grand juries the statutory authority to disclose raw evidentiary materials. Section 939.1, for instance, provides for a grand jury to hold public proceedings only upon a joint request by the foreman and the district attorney or Attorney General, and with the superior court’s approval. (McClatchy, at p. 1179.) Most significantly, section 924.4 permits evidence to be passed on to a succeeding grand jury, indicating that statutory authority is required even for this limited form of disclosure. The legislative history of section 924.4 showed that its enactment was a response to the preexisting prohibition on [228]*228the disclosure of evidence by a grand jury. That prohibition would apply with even more force to public disclosure. “[Fjurther, if before section 924.4 was enacted in 1975 the grand jury was actually empowered to disclose evidence and other materials as it pleased, the Legislature’s grant of specific authority to release such materials to succeeding grand juries would have been unnecessary and the enactment of section 924.4 meaningless.” (McClatchy, at p. 1181.)
In Daily Journal, we concluded that the superior court as well as the grand jury itself has no general inherent power to disclose evidentiary materials, for the same reasons discussed in McClatchy. “To paraphrase McClatchy: Broad though they are, the superior court’s powers to disclose grand jury testimony are only those which the Legislature has deemed appropriate.” (Daily Journal, supra, 20 Cal.4th at p. 1128.) The Daily Journal case began when the superior court responded to media requests by ordering the disclosure of all transcripts and documents from a criminal grand jury investigation into an investment banking firm’s underwriting of Orange County debt offerings. (Id. at pp. 1120-1121.) The Court of Appeal held that the superior court had acted within its “inherent power to order the release of otherwise secret grand jury materials whenever the advantages gained by secrecy are outweighed by a public interest in disclosure.” (Id. at p. 1121.)
We reversed, following the contours of the McClatchy analysis. We noted two other statutes authorizing disclosure, in addition to those mentioned in McClatchy. If a grand jury returns no indictment, section 924.6 permits the court that impaneled the grand jury to disclose relevant and admissible evidence to the parties in a pending or subsequent criminal proceeding. (Daily Journal, supra, 20 Cal.4th at pp. 1127-1128, fn. 6.) And section 929, enacted in 1998, authorizes a civil grand jury, with the court’s approval, to release unprivileged evidentiary materials to the public, so long as the names of witnesses and any facts identifying the witnesses are withheld. (Daily Journal, at p. 1124; for the text of § 929, see fn. 3, ante.) We also reviewed earlier cases adhering to the limits set by the Legislature on the disclosure of grand jury proceedings (People v. Tinder (1862) 19 Cal. 539, 545; Sontag, supra, 64 Cal. at pp. 527-528), and on the powers of the grand jury in general (Allen v. Payne (1934) 1 Cal.2d 607, 608-609 [36 P.2d 614]). (Daily Journal, at pp. 1124-1125; see also McClatchy, supra, 44 Cal.3d at p. 1179.)
In Daily Journal, as in McClatchy, we rested our holding on the need to maintain the integrity of the statutory provisions governing disclosure of grand jury materials. “[I]f superior courts could disclose materials based only on their inherent powers, the statutory rules governing disclosure of grand jury testimony would be swallowed up in that large exception.” (Daily Journal, supra, 20 Cal.4th at p. 1128; see McClatchy, supra, 44 Cal.3d at [229]*229p. 1181.) “Under the legislative scheme, once it has -impaneled and charged the grand jury, the superior court’s powers are narrowly circumscribed; it has very limited authority to review the grand jury’s work and none to dictate its functions. (See Pen. Code, §§ 915-944.) Thus, ... we conclude that whatever exercise of authority to disclose grand jury materials has not been expressly permitted by the Legislature is prohibited.” (Daily Journal, at pp. 1128-1129.)
Goldstein argues that the Court of Appeal properly distinguished McClatchy and Daily Journal on the basis that they involved disclosures to the public, rather than to a private litigant. We disagree. The statutory scheme governs disclosure to litigants (§§ 924.2, 924.6, 938.1) as well as to the public (§§ 929, 938.1, 939.1). If the courts had broad inherent authority to release grand jury materials to litigants in the interests of justice, there would be no need for the statutes permitting disclosure in limited circumstances. We have not distinguished between public and private disclosure. Indeed, we relied on the statutes governing disclosure to litigants to support our holdings restricting public disclosure in both McClatchy and Daily Journal.
Preserving the secrecy of watchdog grand jury proceedings furthers important public interests: witnesses are encouraged to provide candid testimony free from outside influence, and the reputations of those who may be unjustly accused are protected. (McClatchy; supra, 44 Cal.3d at p. 1176.) These considerations are fully applicable when disclosure is sought by a private litigant. Witnesses may very well fear the effects of disclosure to parties interested in the subject of a grand jury investigation, and the reputations of those under investigation may be damaged by revelations made in the course of litigation. Vesting the courts with wide discretion to overlook statutory restrictions on disclosure and provide private parties with access to grand jury evidentiary materials “in the interests of justice” would not only place those secrecy interests at risk, it would also pull the teeth from the statutory limitations.
The Court of Appeal relied on Douglas Oil, supra, 441 U.S. 211, and Sontag, supra, 64 Cal. 525, in ruling that state courts have inherent authority to order the disclosure of grand jury materials in the interests of justice. Neither of these cases, however, supports that conclusion. In Douglas Oil, civil litigants in an antitrust case sought transcripts from a criminal grand jury investigation. (Douglas Oil, at p. 213.) The Douglas Oil court, after noting the interests served by grand jury secrecy (see p. 226, ante), observed: “At the same time, it has been recognized that in some situations justice may demand that discrete portions of transcripts be made available for use in subsequent proceedings. [Citation.] Indeed, recognition of the occasional need for litigants to have access to grand jury transcripts led to the provision [230]*230in Fed. Rule Crim. Proc. 6 (e) (2) (C) (i) that disclosure of grand jury transcripts may be made ‘when so directed by a court preliminarily to or in connection with a judicial proceeding.’ ” (Douglas Oil, at pp. 219-220.)
The Douglas Oil test for determining when the traditional secrecy of the grand jury may be broken,8 and the cases on which the court relied in formulating that test, depend on the authority of the federal rule governing disclosure. (Fed. Rules Crim.Proc., rule 6(e), 18 U.S.C.; Douglas Oil, supra, 441 U.S. at p. 222; United States v. Procter & Gamble (1958) 356 U.S. 677, 679, fn. 1, 681, fn. 5 [2 L.Ed.2d 1077, 78 S.Ct. 983]; Dennis v. United States (1966) 384 U.S. 855, 869-870 [16 L.Ed.2d 973, 86 S.Ct. 1840].) There is no similar California provision for disclosure “ ‘when so directed by a court.’ ”9 (Douglas Oil, at p. 220; see current Fed. Rules Crim.Proc., rule 6(e)(3)(E), 18 U.S.C.; People v. Superior Court (Mouchaourab) (2000) 78 Cal.App.4th 403, 427 [92 Cal.Rptr.2d 829].) The Court of Appeal believed the broad terms of the federal rule merely reflect the judiciary’s “inherent responsibility to prevent injustice.” California, however, has taken a different approach. Our statutes give the courts discretion to order disclosure only in limited circumstances. As McClatchy and Daily Journal make clear, when the Legislature has placed specific restrictions on the release of grand jury materials, and refrained from providing the courts with general authority to go further, there is no room for the courts to fashion broadly applicable standards like those articulated in Douglas Oil.
The Sontag opinion says nothing different. There, in proceedings to set aside an indictment, a grand juror was held in contempt of court for refusing to disclose whether he had voted for the indictment. This court observed: “The form of the oath, in general use for centuries, binds the grand juror to preserve inviolate the secrets of the grand jury room. Public policy would seem to forbid vain disclosures made to gratify idle curiosity. ‘But,’ says Thompson and Merriam, ‘when, for the purposes of public justice, or for the protection of private rights, it becomes necessary, in a court of justice, to disclose the proceedings of the grand jury, the better authorities now hold that this may be done. . . .’ (Thom. & Mer. on Juries, § 703.)” (Sontag, supra, 64 Cal. at p. 526.)
[231]*231The Court of Appeal seized on the last sentence quoted above as authority for its holding. However, the Sontag court dispelled any notion that California courts have broad inherent power to order the disclosure of grand jury proceedings in the interests of justice. It noted that some cases cited by the Thompson and Merriam treatise permitted grand jurors to disclose whether there were 12 votes for indictment, but others forbade such inquiry, and no case held that grand jurors could be compelled to reveal their own votes. (Sontag, supra, 64 Cal. at pp. 526-527.) The court did not then formulate a judicial disclosure policy. To the contrary, it declared: “In this State the whole matter is regulated by statute.”10 (64 Cal. at p. 527.)
The governing statute then, as now, prohibited grand jurors from disclosing their votes. (Sontag, supra, 64 Cal. at p. 527; see § 924.2.) The Sontag court noted that the statutes recognized exceptions only to permit testing the consistency of witnesses’ grand jury testimony with their subsequent testimony. (Sontag, at p. 527.) The court rejected the argument that in the case before it, the grand juror’s testimony was required for purposes of the defendant’s motion to set aside the indictment. “The mere inconvenience or difficulty of proving the fact ought not to overrule the many grave objections to a procedure not only not directly authorized, but expressly forbidden by the Code, which may interfere with the complete freedom of exposure of alleged offenses which it is the design of the institution of grand juries to secure, and conflict with other principles of public policy which are sub-served by keeping inviolate the secrets of the grand jury room—except when their disclosure is absolutely necessary.” (Sontag, at p. 528.)
Neither the Court of Appeal nor Goldstein, in his briefing here, relied on the Sontag court’s mention of absolute necessity, and for obvious reasons. The Court of Appeal did not restrict its rule permitting disclosure of grand jury materials to instances of absolute necessity. Goldstein, as the grand jury points out, has the grand jury report and was able to secure his release on habeas corpus without the evidentiary materials he is seeking for use in his civil rights lawsuit. Thus, it is apparent that his position is not one of [232]*232necessity, but of “mere inconvenience or difficulty of proving the fact[s]” needed to make his civil case in federal court. (Sontag, supra, 64 Cal. at p. 528.)11
We turn now to Goldstein’s statutory claims, which were summarily rejected by the Court of Appeal. Goldstein relies, as he did below, on sections 924.2 and 929. While the Court of Appeal properly found no basis for disclosure under section 929, we conclude that section 924.2 does apply to Goldstein’s request, though not as broadly as he asserts.
Section 929 was enacted in 1998, years after the issuance of the grand jury report at issue here. Even if it were applicable to Goldstein’s request (see Californians for Disability Rights v. Mervyn’s, LLC (2006) 39 Cal.4th 223, 230-231 [46 Cal.Rptr.3d 57, 138 P.3d 207]), this statute allows a grand jury, with court approval, to make evidentiary materials “available to the public” after redacting the names of witnesses and any information reflecting their identity. (§ 929.) Here, the 1990 grand jury performed no such redaction, and released no information to the public. Rather, it specified that the materials “be preserved under secure conditions.” The trial court order implementing this directive strictly prohibited viewing, inspection, or copying except by permission of the court. Thus, neither the grand jury nor the court made evidentiary materials “available to the public,” and section 929 would not permit the discovery Goldstein seeks.
Goldstein has a better argument under section 924.2, which allows “[a]ny court [to] require a grand juror to disclose the testimony of a witness [233]*233examined before the grand jury, for the purpose of ascertaining whether it is consistent with that given by the witness before the court.” Goldstein overstates the scope of this statute, which permits disclosure only for impeachment of witnesses, not for general discovery. However, his claim that section 924.2 applies to transcripts of grand jury testimony has merit.
The Court of Appeal ruled that section 924.2 “has no application here,” observing that the statute was meant to limit the circumstances in which grand jurors could be called as witnesses. This reading of the statute is unduly restrictive. As Goldstein notes, the relevant provisions of section 924.2 date from a period when grand jury proceedings were not transcribed. (See Stats. 1851, ch. 29, § 218, pp. 235-236; former § 926, enacted in 1872; Sontag, supra, 64 Cal. at p. 527; People v. Superior Court (Mouchaourab), supra, 78 Cal.App.4th at p. 416.) Wien the Legislature did provide for transcription, it evidently did so to facilitate the use of grand jury testimony for impeachment purposes.12
Given this background, section 924.2 should not be construed to bar the use of transcripts of grand jury witness testimony. “ ‘[Ojur task is to select the construction that comports most closely with the Legislature’s apparent intent, with a view to promoting rather than defeating the [statute’s] general purpose, and to avoid a construction that would lead to unreasonable, impractical, or arbitrary results.’ ” (Commission on Peace Officer Standards & Training v. Superior Court (2007) 42 Cal.4th 278, 290 [64 Cal.Rptr.3d 661, 165 P.3d 462]; see also People v. Superior Court (Mouchaourab), supra, 78 Cal.App.4th at p. 428.) It would be unreasonable to require grand jurors to appear at trial to provide their recollections of witness testimony, when transcripts of that testimony are readily available.
The Court of Appeal also reasoned that Goldstein made no claim that a witness at his federal trial would give testimony inconsistent with the witness’s grand jury testimony. However, section 924.2 does not require a party to make a showing or claim of conflicting testimony without access to [234]*234the transcripts in some form. The statute contemplates disclosure “for the purpose of ascertaining whether [grand jury testimony] is consistent with that given by the witness before the court.” (§ 924.2, italics added.)
Thus, the Court of Appeal erred by holding that section 924.2 does not apply to Goldstein’s request for disclosure. But Goldstein goes too far by arguing that section 924.2 does not restrict the trial court’s discretion over the extent of the grand jury material that may be disclosed. He claims that all the grand jury transcripts and other evidentiary materials may be released to him under section 924.2. Nothing in the statutory language supports that interpretation, which would entirely “swallow[] up” the limited provisions for disclosure prescribed by the Legislature. (Daily Journal, supra, 20 Cal.4th at p. 1128.) It would transform this narrow exception, expressly confined to impeachment, into a general discovery provision.
The trial court denied Goldstein’s request under section 924.2 in part because no witness was before it. The court correctly interpreted the statute in this respect. Section 924.2 permits disclosure only for purposes of impeachment. It does not authorize a litigant to obtain unlimited disclosure in advance of a witness’s testimony. To preserve the narrow scope of the statute, the appropriate procedure is for the witness to testify first. Counsel may then request the court to examine the transcript of that witness’s grand jury testimony in camera, to determine if it provides potentially relevant impeachment material. If it does, the court may release the relevant pages to counsel, with a protective order restricting the use of the material to impeachment.
We leave it for the superior court and the federal district court, with the cooperation of the parties, to sort out additional appropriate procedures for providing Goldstein with access to the testimony of grand jury witnesses under section 924.2, should he seek that limited form of disclosure.
DISPOSITION
The judgment of the Court of Appeal is reversed.
George, C. J., Kennard, J., Baxter, J., Werdegar, J., and Chin, J., concurred.
