Opinion
In this case we must determine the validity of an order, entered prior to trial in a criminal action, that authorizes the prosecution to refuse to disclose to the defendants or their counsel, both prior to and at trial, the identities of the crucial witnesses whom the prosecution proposes to call at trial, on the ground that disclosure of the identities of the witnesses is likely to pose a significant danger to their safety.
Protecting the safety of witnesses unquestionably is of the utmost importance, and a trial court has broad discretion to deny, restrict, or defer disclosure of a witness’s identity prior to trial in order to provide such protection (Pen. Code, § 1054.7). As we shall explain, however, we conclude in light of controlling constitutional authorities that the trial court and the Court of Appeal erred in determining that, when the risk to a witness is sufficiently grave, the identity of the witness may be permanently withheld from a defendant and the witness may testify anonymously at trial—even when the witness is a crucial prosecution witness and withholding the witness’s identity will impair significantly the defendant’s ability to investigate and cross-examine the witness.
As discussed hereafter, numerous decisions of both the United States Supreme Court and the California courts establish that whenever nondisclosure of a witness’s identity will prevent the effective investigation and cross-examination of a crucial witness, the confrontation clause precludes the prosecution from relying upon the witness’s testimony at trial while refusing to disclose the witness’s identity. As the United States Supreme Court has explained: “[W]hen the credibility of a witness is in issue, the very
*1126
starting point in ‘exposing falsehood and bringing out the truth’ through cross-examination must necessarily be to ask the witness who he is and where he lives. The witnesses] name and address open countless avenues of in-court examination and out-of-court investigation.
To forbid this most rudimentary inquiry at the threshold is effectively to emasculate the right of cross-examination
itself.”
{Smith v. Illinois
(1968)
Accordingly, we conclude that the challenged order must be vacated insofar as it authorizes, in advance of trial and without regard to the evidence and circumstances as they then may appear, the prosecution permanently to withhold the identity of these prosecution witnesses from the defense. At the same time, however, we emphasize that the trial court remains free to fashion a more limited order denying, restricting, or deferring disclosure of the identity of each witness before trial (including limiting disclosure to defendants’ counsel), as long as that order does not impermissibly impair defendants’ right to confront and cross-examine the witnesses effectively at trial.
I.
On February 6, 1993, during the noon hour, Jose Uribe, an inmate at the Los Angeles County jail, was killed in his cell, having been stabbed 37 times with a contraband knife described as a shank. Three other inmates allegedly witnessed the incident.
Following an investigation by law enforcement officials, a complaint was filed charging defendants Joaquin Alvarado and Jorge Lopez with the first degree murder of Uribe. A third defendant, Frank Marquez, also was charged but is not a party to this proceeding. The prosecution provided discovery to the defense indicating that three inmates witnessed the killing. A magistrate ordered the prosecution to рrovide the defense with the identities of the witnesses prior to the commencement of the preliminary hearing, pursuant to Penal Code sections 1054.1, subdivision (a), and 1054.5. 1
Instead of complying with the magistrate’s order, the prosecution presented its case to a grand jury, which returned an indictment charging defendant Alvarado with murder (and alleging a prior-murder special circumstance) and conspiracy to commit murder, and charging defendant Lopez with murder, conspiracy to commit murder, and possession of a shank while in custody (on three occasions unrelated to the present incident). (§§ 187, 190.2, subd. (a)(2), 182, subd. (a)(1), 4574, subd. (a).) The prosecution is seeking the death penalty against Alvarado but not against Lopez.
*1127 The prosecution provided defendants with transcripts of the grand jury proceedings, in which the three inmate eyewitnesses are identified only as witnesses 1, 2, and 3. We summarize the testimony of the three witnesses before the grand jury.
Witness 1 testified that on the day of the murder, he was housed in cell No. 12. Witness 1 heard Marquez, a jail trusty, ask one of witness l’s two cellmates in Spanish for some extra jail clothing, mentioning something about a snitch. Witness 1 gave Marquez his shirt, hoping to curry favor with Hispanic inmates. Witness 1 remained in his cell during the noon hour because he was tired. He saw a group of five inmates, including defendants, near his cell. He then heard an altercation and observed the same group of five inmates leave the area.
Two days after the murder, during the course of the sheriff’s department’s investigation, witness 1 identified a photograph of Marquez as depicting the pеrson to whom he gave his shirt, but six months later he selected another photograph identifying a different individual. Witness 1 told the grand jury that he had been confused regarding his earlier photographic identification. Witness 1 further testified that defendants were in the group of inmates he saw near his cell and that on the day immediately preceding his testimony before the grand jury, he was placed in the same jail cell as defendant Alvarado, who threatened to harm him if he testified.
Witness 2 testified that, on the morning of Uribe’s death, Marquez came to cell No. 11, where witness 2 was housed. Marquez spoke to witness 2’s cellmates in Spanish. Witness 2 believed that Marquez said a snitch was going to be dealt with in cell No. 10, and said witness 2 should stay away from cell No. 10. Approximately 10 minutes later, witness 2 heard a Black trusty inform certain Black inmates to stay away from the end of the row where cell No. 10 was located. Witness 2 remained in his cell around noon instead of going to lunch, because he wanted to eat the food he had purchased that morning at the commissary.
Around noon, witness 2 saw defendants Alvarado and Lopez, who were not assigned to cell No. 10, enter that cell with another inmate who was housed there. Witness 2 then heard an altercation inside cell No. 10 and something being said about being a snitch. Shortly thereafter, witness 2 saw Lopez give a bloody shirt to Marquez outside cell No. 10. Witness 2 also saw a bloody body lying under a bed inside cell No. 10. Marquez told witness 2 to return to his cell because the matter did not involve him.
As part of the investigation into Uribe’s murder, witness 2 was shown photographs of inmates who had been in the area. Witness 2 identified *1128 Marquez, Lopez, and Alvarado. (Witness 2 initially identified a different individual as having accompanied Lopez into cell No. 10. When thereafter shown Alvarado’s photograph, witness 2 stated that his earlier identification had been mistaken.)
Witness 3 was a jail trusty assigned to sweep the module that contained cell Nos. 10, 11, and 12. On the morning of the murder, he saw Marquez wrap a shank inside a shirt and give it to another Hispanic inmate. After lunch, witness 3 saw Marquez take a shirt from someone on the same row.
The prosecution provided the defense with the grand jury transcripts and information regarding the witnesses’ criminal histories, but did not provide the names or photographs of witnesses 1, 2, or 3. 2 The defense continued to seek the witnesses’ true names and addresses. The prosecution then sought a protective order, authorizing it permanently to withhold disclosure of the witnesses’ identities and photographs from defendants or their counsel on the ground that disclosure would place the witnesses’ lives in danger.
Over defendants’ objections, the trial court held a series of in camera hearings, from which the defense was excluded, to permit the prosecution to demonstrate good cause why disclosure of the witnesses’ names and photographs should be denied. (§ 1054.7.) Based upon the evidence adduced at these hearings, the trial court found as follows:
“The evidence presented clearly established that witnesses 1 through 3 are in serious danger as a result of their participation in this case and that the disclosure of their names would likely increase the danger to them. Several facts support this conclusion, including the following:
“(1) The homicide is believed to have been ordered by the Mexican Mafia, a notorious prison gang, and that the defendants, who are not members of the gang, committed the homicide to gain favor with the Mexican Mafia.
“(2) The Mexican Mafia is well-known for retaliatory acts against . . . informants and government witnesses, including murder. ftO Information disclosed in camera documented 12 incidents of murder or attempted murder at the county jail of inmates between 1988 through 1991 which were committed by or at the direction of the Mexican Mafia. The additional five murders linked to the Mexican Mafia during this period of time were committed on persons who were not incarcerated. [^Q The Mexican Mafia is *1129 believed to have ordered the murders of witnesses in protective custody and incarcerated in other states ....
“(3) The Mexican Mafia has an excellent intelligence network which includes sources in several public agencies and is able to obtain confidential information. HD ... HD Penetration [by] the Mexican Mafia of penal institutions is so extensive that one in camera witness described the organization as having ‘de facto control’ over all penal institutions in California.
“(4) . . . [T]he danger the Mexican Mafia poses to government witnesses is extreme. In camera, a witness stated that the Mexican Mafia has ordered so many hits and there are so many witnesses in protective custody that we cannot adequately protect them all.
“(5) The Mexican Mafia requires documеntation which identifies an individual as a government witness before a contract to kill the witness is approved. The procedure for issuing contracts was described as follows: HD For contracts to be issued, one Mexican Mafia member alone cannot give the contract. He has to have that contract approved. HO The contract is approved in a manner where they meet, two or three members meet. They are presented with evidence. They have . . . what you would call a trial. It is informal. This evidence includes transcripts or paperwork . . . that would indict this person who has been a witness and that is why the name is so important.
“(6) A witness in the instant case was attacked and cut in jail after the killing in this case. The attacker was a member of the prison gang aligned with the Mexican Mafia and warned the witness not to testify. HD One of the defendants in this case threatened a witness while the witness was in protective custody and told the witness somebody would get him. HO Someone wrote on a wall while a witness was in a court holding cell that the witness was dead. And that the witness was a snitch at the time when the witness was in protective custody.
“(7) In the instant case, the homicide was committed in a manner which suggests highly organized criminal activity involving several persons. HQ The victim arrived at the institution a single day or at most two days before the killing. This fact suggests that the group responsible for his killing had intelligence and organization. It was known that the [victim] was coming, where he would be and how to get to him. HO This sophisticated criminal activity involving the obtaining of shanks which, of course, [are] illegal to possess in the jail, getting the shanks to the floor [where] they could be used, obtaining the extra clothing so the killer could rid themselves [sic] of the blood-stained clothes, getting rid of the blood-stained clothes. HQ The sophistication of the killing indicates no one is safe inside the county jail system and I think that also obtains to persons who are in prison within California and in prisons outside of California.
*1130 “Based on the foregoing and the other facts disclosed to the court in camera, it is clear that the witnesses 1 through 3 are in danger and that disclosure of their names would increase the risk of possible danger to them with a resulting possible los[s] of evidence; that is, their testimony, which has not been preserved in any usable way. HO So I find good cause has been shown to support that there is a danger to these witnesses.
“But I must say I continue to be troubled by the People’s request to not turn over the names. It is a difficult issue for me. And even though I think good cause exists, I certainly am persuaded by [counsel for defendant Alvarado] Mr. Crain’s argument and the arguments of counsel that for them to investigate the case in this situation, it makes it almost impossible to investigate without the names. . . .”
Based upon the foregoing findings, the trial court concluded that good cause for nondisclosure of the witnesses’ true names had been established. The court therefore issued the following minute order: “[The] People’s request to withhold the names of witnesses from the defense is granted. The witnesses will be made available for interview by defense counsel 30 (thirty) days before trial. The witnesses are not required to state their names, but, may do so at their own volition.”
Defendants thereafter sought writ review of the trial court’s order. The Court of Appeal denied defendants’ petitions for writ of mandate. Defendants thereafter sought review from this court. We granted review and transferred the matters to the Court of Appeal, with directions to that court to vacate its order denying mandate and to issue an alternative writ to be heard before that court. The Court of Appeal, upon discovering a discrepancy between the trial court’s minute order and the reporter’s transcript, remanded the case to the trial court, which issued a new minute order clarifying its ruling and providing as follows: (1) the prosecution is authorized permanently to withhold from the defense the identities of the three witnesses; (2) the prosecution is to produce the witnesses for interview by defense counsel 30 days prior to trial, although the witnesses are not required to speak to defense counsel, and if they do, they may—but are not required to— disclose their names; (3) if defense counsel learn the witnesses’ names, they may not disclose the names to defendants; and (4) at trial, the witnesses may —but are not required to—disclose their names, but their appearance will not be disguised.
Both defendants thereafter sought further writ review from the Court of Appeal, which consolidated the two petitions, issued an order to show cause, and ultimately resolved the matter in a written opinion rendered by a divided court.
*1131
In its opinion, the majority of the Court of Appeal determined that the trial court properly had exercised its discretion in authorizing the prosecution permanently to withhold the witnesses’ identities from the defense, based upon the trial court’s finding that disclosure of the witnesses’ names “would place them in mortal danger. . . .” In so holding, the majority acknowledged that under the trial court’s order “[defendants will have difficulty obtaining complete information about the witnesses’ location and ability to observe and testify about the crime. Moreover, defendants will be unable to obtain complete impeaching information, such as the witnesses’ reputation for truthfulness or dishonesty, previous history and accuracy of providing information to law enforcement, and other motives to fabricate, such as revenge or reduction or dismissal of their own charges.” In sum, the majority conceded that the trial court’s nondisclosure order would seriously limit defendants’ effective investigation and cross-examination of the witnesses, “significantly impairing]” defendants’ constitutional rights to confrontation and to due process of law. Nonetheless, the majority concluded that in light of the potentially grave danger to the witnesses, the impairment of defendants’ ability to cross-examine and impeach the witnesses was not unconstitutional. In reaching this conclusion, the Court of Appeal majority expressly disagreed with the conclusion reached in
People
v.
Brandow
(1970)
The dissenting justice in the Court of Appeal challenged the majority’s analysis of the relevant case law and criticized the majority for according undue weight to the threat of retaliation against the prosecution’s witnesses at the expense of defendants’ constitutional rights. Questioning the ultimate effectiveness of the trial court’s nondisclosure order, the dissent observed that “in addition to trying to dissuade adverse witnesses from *1132 testifying, it is also part of the Mexican Mafia’s arsenal to retaliate against such witnesses once their testimony has been given. Here, although the likelihood that the People will be able to bring this case to trial may be enhanced by the order of nondisclosure, once the witnesses have appeared in open court and thereby been subjected to the scrutiny of the Mexican Mafia’s extensive intelligence network, what protection the nondisclosure order previously afforded could well be rendered meaningless.”
We again granted defendants’ petitions for review, on this occasion in order for us to determine whether the trial court’s order, by permitting the prosecution’s crucial witnesses to testify anonymously at trial, violates defendants’ constitutional rights to due process of law and to confront the witnesses against them.
II.
Proposition 115, approved by the voters in June 1990, included provisions amending the California Constitution and the Penal Code in numerous respects, one of which explicitly authorizes reciprocal discovery in criminal cases. (Cal. Const., art. I, § 30, subd. (c); Pen. Code § 1054 et seq.;
People
v.
Tillis
(1998)
As noted, on the basis of the evidence presented by the prosecution at the in camera hearing in this case, the trial court found that good cause existed to permit the prosecution to withhold the identities of the witnesses because disclosure was likely to pose a serious danger to their safety. The court ruled that the prosecution was required only to make the witnesses available for interviews by the defense 30 days prior to trial, and that the witnesses need *1134 not disclose their names or even submit to the interviews. On remand from the Court of Appeal, the trial court subsequently clarified its order, reiterating that the prosecution must make the witnesses available for interviews by the defense, but further specifying that the witnesses’ identities need not be disclosed to the defense unless the witnesses themselves choose to reveal their identities (in which case the attorneys would be precluded from disclosing the witnesses’ identities to their clients). The trial court further clarified that its intent was to authorize the prosecution to withhold the witnesses’ identities (and their photographs) from defendants and their counsel both at the pretrial discovery stage and at trial. The trial court further ordered that the witnesses need not submit to interviews by the defense.
Defendants do not contend that the trial court’s finding that disclosure of the witnesses’ names and photographs would pose a potential danger to the safety of the witnesses does not constitute “good cause” within the meaning of section 1054.7, but they maintain that, under the circumstances of the present case, the trial court’s order—upholding the prosecution’s authority to withhold disclosure of the witnesses’ identities at trial—violates their rights, as guaranteed by the United States Constitution, to due process of law and to confront the witnesses against them. The resolution of this case turns upon these federal constitutional issues. 6
III.
In analyzing defendants’ federal constitutional claims, it is helpful to discuss separately two aspects of the trial court order before us: (1) the validity of that order insofar as it permits the prosecution to decline to disclose the witnesses’ identities to the defense before trial, and (2) the validity of the trial court’s order insofar as it permits the prosecution to continue to withhold the witnesses’ identities at trial.
With regard to the first issue—i.e., disclosure of the witnesses’ identities before trial—section 1054.7 establishes that a trial court has discretion to deny, restrict, or defer disclosure for good cause. Good cause, as defined in the statute, expressly includes “threats or possible danger to the safety of a victim or witness.”
(Ibid.)
Petitioners have cited no authority that suggests that the statute, in this respect, is unconstitutional under either the confrontation clause or the due process clause. (See generally
Pennsylvania v. Ritchie
(1987)
Even before Proposition 115 added section 1054.7 to the Penal Code, this court had recognized that a trial court retains considerаble discretion to protect a witness’s identity before trial. In
People v. Lopez
(1963)
On appeal of their subsequent convictions, the defendants contended that the trial court committed prejudicial error in denying their motion for immediate disclosure of the identities of the prospective witnesses prior to trial. In Lopez, this court rejected the contention, explaining that “zn special circumstances [the state may] have cogent reasons for keeping confidential *1136 —in order to give some assurance that the truth can be presented—the names of prospective witnesses. There must be a balancing of the right of a defendant to discover potentially material witnesses with the probability that such discovery might lead to the elimination of an adverse witness or the influencing of his testimony. In balancing these competing factors the trial court must be allowed great discretion. [Citation.] . . . ftO The court’s order delaying disclosure was, undoubtedly, a conscientious effort on the part of the court to balance the claimed right of defendants to immediate disclosure with realistic danger inherent in such disclosure. It is the timeliness rather than the. immediacy of disclosure which should control. In view of the facts before the court, we cannot say that the court abused its discretion by ordering disclosure delayed until shortly before the subject witnesses were to be called.” {People v. Lopez, supra, 60 Cal.2d at pp. 246-247, italics in the original.)
In the case before us, the evidence presented to the trial court clearly justified its order protecting the witnesses’ identities before trial. In view of the circumstances of the offense—a jailhouse murder with likely prison gang involvement and crucial prosecution witnesses who themselves were jailhouse inmates and thus particularly vulnerable to threats, coercion, or violent acts of other inmates, the trial court clearly had discretion to permit the prosecution to withhold pretrial disclosure of the witnesses’ names and photographs. Particularly in a capital case, where pretrial preparation and investigation often extend over a considerable period of time, early disclosure of the identity of a vulnerable and threatened witness greatly may increase the danger of “the elimination of an adverse witness or the influencing of his testimony.”
{People
v.
Lopez, supra,
Accordingly, we conclude the challenged order clearly is valid insofar as it authorizes the prosecution to refrain from immediately disclosing the inmate witnesses’ identities to the defense.
IV.
As noted, however, the trial court’s order in this case—particularly as clarified after remand—did not simply authorize the prosecution to deny the disclosure of the witnesses’ identities befоre trial, but rather went further and ruled that the prosecution permanently could withhold the witnesses’ identities from the defense, even during (and after) their testimony at trial. Although the Court of Appeal recognized that this aspect of the order would, as a practical matter, seriously impair defendants’ ability to investigate the witnesses’ backgrounds and credibility (as the trial court also recognized) and would affect adversely their constitutional right of cross-examination, *1137 the Court of Appeal majority ultimately concluded that, because of the seriousness of the danger faced by the witnesses, even the complete withholding of this information from the defense at trial does not violate defendants’ constitutional rights.
As the Court of Appeal also recognized, the aspect of the trial court’s order authorizing the prosecution to withhold permanently from the defense the names of witnesses who are to testify at trial directly implicates defendants’ rights under the confrontation clause of the federal Constitution. Thus, in analyzing the validity of the Court of Appeal’s decision nonetheless to uphold the trial court’s order permitting nondisclosure at trial, we examine the governing authorities under the federal confrontation clause. 7
A.
The Sixth Amendment guarantees the right of an accused in a criminal prosecution “ ‘to be confronted with the witnesses against him.’ ”
CDelaware v. Van Arsdall
(1986)
“[T]he right of an accused to be confronted with the witnesses against him must be determined by the same standards whether the right is denied in a
*1138
federal or state proceeding. . . .”

In
Alford
v.
United States
(1931)
In reversing the judgment on the ground that the trial court’s curtailment of the cross-examination of the prosecution witness was an аbuse of discretion and constituted prejudicial error, the United States Supreme Court held that “[c]ross-examination of a witness is a matter of right. [Citation.] Its permissible purposes, among others, are that the witness may be identified with his community so that independent testimony may be sought and offered of his reputation for veracity in his own neighborhood . ... HQ ... It is the essence of a fair trial that reasonable latitude be given the cross-examiner, even though he is unable to state to the court what facts a reasonable cross-examination might develop. Prejudice ensues from a denial of the opportunity to place the witness in his proper setting and put the
*1140
weight of his testimony and his credibility to a test, without which the jury cannot fairly appraise them. [Citations.] . . . HQ . . . The question ‘Where do you live?’ was not only an appropriate preliminary to the cross-examination of the witness, but on its face, without any such declaration of purpose as was made by counsel here, was an essential step in identifying the witness with his environment, to which cross-examination may always be directed. [Citations.]”
(Alford, supra,
In
Smith
v.
Illinois, supra,
In reversing the judgment because of federal constitutional error, the United States Supreme Court observed that there had
not been a complete denial
of the defendant’s right of cross-examination. “But the [defendant] was denied the right to ask the principal prosecution witness either his name or where lived, although the witness admitted that the name he had first given was false.
Yet when the credibility of a witness is in issue, the very starting point in ‘exposing falsehood and bringing out the truth’ through cross-examination must necessarily be to ask the witness who he is and where he lives. The witnesses]
name and address open countless avenues of in-court examination and out-of-court investigation.
To forbid this most rudimentary inquiry at the threshold is effectively to emasculate the right of cross-examination itself.” (Smith, supra,
*1141 B.
In 1970, two years after the United States Supreme Court handed down its decision in
Smith, supra,
On appeal from his conviction, the defendant in
Brandow
contended that the trial court erred in sustaining the prosecutor’s objection, thereby depriving the defendant of his right of confrontation. Citing
Smith, supra,
C.
The People urge us to consider several state and federal judicial decisions that assertedly embrace the proposition that a defendant’s right of confrontation properly may be balanced against the need to protect a witness’s safety. The People contend that under such a balancing process, when the risk posed to a witness’s safety is grave enough, a defendant’s right to be informed of the identity of the witness properly may give way even if the witness’s testimony is crucial to the prosecution’s case. The Court of Appeal majority endorsed this position.
In observing that
Alford, supra,
*1144
In other cases relied upon by the People, the identity or address of the witness
actually was made available
to defense counsel privately, or was discovered by the defense prior to trial. Thus, nondisclosure was limited to events occurring in open court and did not preclude defense efforts to investigate the witness for the purpose of obtaining material that might be useful in cross-examination. Therefore, these cases, too, are distinguishable from the case presently before us. (See, e.g.,
People v. Ramirez
(1997)
Significantly, in all those decisions in which a witness’s name or address was deemed crucial, or the prosecution failed to allege a basis for nondisclosure of identifying information, the courts uniformly have concluded that disclosure at trial is required. (See, e.g.,
Miller v. Superior Court
(1979) 99
*1146
Cal.App.3d 381, 386 [
In short, although the People correctly assert that the confrontation clause does not establish an
absolute
rule that a witness’s true identity always must be disclosed,
in every case in which the testimony of a witness has been found crucial to the prosecution’s case the courts have determined that it is improper at trial to withhold information (for example, the name or address of the
witness)
essential to the defendant’s ability to conduct an effective cross-examination.
(Accord,
Roviaro v. United States, supra,
In the present case, the defense argues that the witnesses whose identities are at issue clearly are crucial witnesses whose veracity and credibility are *1147 likely to be central to the prosecution’s case. As noted, the witnesses’ grand jury testimony suggests they were in close proximity to the murder and witnessed events related to the charged offenses. Thus, under the cases discussed above, should the witnesses provide such crucial testimony at trial, the confrontation clause would prohibit the prosecution from relying upon this testimony while refusing to disclose the identities of the witnesses under circumstances in which such nondisclosure would significantly impair the defense’s ability to investigate or effectively cross-examine them.
D.
The People contend that, although they have not identified the witnesses in question by their true names, the impact of such nondisclosure has been mitigated by the prosecution’s submission of other relevant information to the defense, including the module, row, and cell number occupied by each of the witnesses at the time of the crime as well as the witnesses’ criminal histories. (See
People
v.
Marshall
(1996)
In response, defendants contend that the limited information provided to them is inadequate to permit effective cross-examination. Defense counsel *1148 insist that without access to the witnesses’ identities, they will be unable to determine whether the witnesses (1) were present at the time and place of the killing, (2) harbored grudges against either or both defendants, (3) had a motive to kill the victim themselves and accuse defendants in order to dispel suspicion from themselves, (4) made inconsistent statements to others regarding relevant aspects of the case, and (5) had reputations for dishonesty.
We already have explained that the order presently on review, insofar as it relates to
pretrial
discovery, represents a reasonable exercise of discretion under section 1054.7 and a “conscientious effort”
{People
v. Lopez,
supra,
The People further contend that once the crucial witnesses appear in court at trial, defendants “can advise their attorneys of any prior contacts with these witnesses and any other information they might have concerning these witnesses,” and that at that point defendants may be able to obtain a continuance in order to investigate the witnesses. The trial court’s order in this case, however, is based upon the premise that the witnesses’, identities need not be disclosed at trial under any circumstances. We do not believe such an order can be defended, without full consideration—in light of the relevant evidence and circumstances—of the defense’s need for *1149 affirmative disclosure, solely on the assumption that the witnesses’ appearance at trial in any event will reveal their identities. 13
Accordingly, we conclude that the trial court erred in ruling, on the record before it, that the witnesses in question may testify anonymously at trial. 14
As emphasized at the outset of this opinion, we are keenly aware of the serious nature and magnitude of the problem of witness intimidation. 15 Further, we agree that the state’s ability to afford protection to witnesses *1150 whose testimony is crucial to the conduct of criminal proceedings is an absolutely essential element of the criminal justice system. As we have explained, a trial court has broad discretion to postpone disclosure of a prospective witness’s identity in order to protect his or her safety, and may restrict such pretrial disclosure to defense counsel (and ancillary personnel) alone.
A trial court also retains broad discretion to control courtroom proceedings in a manner directed toward promoting the safety of witnesses. (See, e.g., § 868.7, subd. (a)(2) [upon motion of the prosecutor, a magistrate may close the examination of a witness “[w]hose life would be subject to a substantial risk in appearing before the general public”]; see also § 686.2 [authorizing the trial court to remove any spectator who is intimidating a witness]; § 867 [authorizing the magistrate to exclude potential and actual witnesses upon motion of either party]; § 868 [authorizing the magistrate to exclude the public upon the request of the defendant and a finding by the magistrate “that exclusion of the public is necessary in order to protect the defendant’s right to a fair and imрartial trial”];
People
v.
Woodward
(1992)
The state retains numerous other means of affording protection to a potential witness, including the provision of protective surveillance and
*1151
housing, relocation, documents to establish a new identity, and the transfer of an incarcerated witness to another prison, either within or outside of California. (See, e.g., §§ 14020 et seq. [establishing state Witness Protection Program and authorizing reimbursement to local entities for witness protection expenses], 11189 et seq. [adopting Interstate Corrections Compact authorizing confinement of inmates in other states].)
16
Although none of the measures specifically authorized by these legislative enactments can guarantee the safety of a witness, they do provide mechanisms by which the state can help reduce the risks that he or she faces. Furthermore, the state vigorously may enforce the numerous stringent criminal sanctions that are available against witness harassment and intimidation. (See, e.g., §§ 136 et seq. [establishing a variety of witness intimidation offenses], 190.2, subd. (a)(10) [authorizing the death penalty for the murder of a witness to a crime “who was intentionally killed for the purpose of preventing his or her testimony in a criminal or juvenile proceeding”];
People v. Jones
(1996)
As has been established by the judicial decisions that we have discussed above, however, the state’s legitimate interest in protecting individuals who, by chance or otherwise, happen to become witnesses to a criminal offense cannot justify depriving the defendant of a fair trial. Thus, when nondisclosure of the identity of a crucial witness will preclude effective investigation and cross-examination of that witness, the confrontation clause does not permit the prosecution to rely upon the testimony of that witness at trial while refusing to disclose his or her identity. As this court observed more than 40 years ago, “however praiseworthy was the prosecution’s motive in protecting the [witness] from the threat of reprisal^] [s]uch motives and purposes cannot prevail when, as here, they inevitably result, intentionally or unintentionally, in depriving the defendant of a fair trial.”
(People v. Kiihoa
(1960)
V.
As we have explained, the serious threat to the witnesses’ safety disclosed by the evidence presented by the prosecution in this case clearly justified *1152 delaying disclosure of the witnesses’ identities to the defense, but the trial court’s order went beyond constitutional bounds in determining that, notwithstanding the significant impairment of defendants’ ability to investigate or cross-examine the witnesses or the apparently crucial nature оf the witnesses’ proposed testimony, the prosecution could withhold the identities of “witnesses 1, 2, and 3” from the defense for the duration of the proceedings and have them testify anonymously at trial. Accordingly, we reverse the judgment of the Court of Appeal insofar as it upholds this aspect of the trial court’s order.
We conclude that the trial court should be directed to vacate the challenged order and, because that order was entered some time ago and a variety of circumstances—including the location and situation of the witnesses—may have changed materially in the interim, the trial court should be permitted to fashion a revised order in light of the conclusions expressed in this opinion.
VI.
For the reasons set forth above, we reverse the judgment of the Court of Appeal and remand the matter to that court with instructions to issue a writ directing the trial court to vacate the challenged order, and to conduct further proceedings and issue a new order consistent with the reasoning set forth in this opinion.
Mosk, J., Kennard, J., Baxter, J., Werdegar, J., Chin, J., and Brown, J., concurred.
The petition of real party in interest for a rehearing was denied November 15, 2000, and the opinion was modified to read as printed above.
Notes
Unless otherwise specified, all further statutory references are to the Penal Code.
The prosecution also provided the defense with information describing the witnesses’ custodial status and with the police reports of their prior crimes. Copies of reports of interviews of other inmates were madе available to the defense. Additionally, the prosecution provided the names and photographs of 33 other inmates who, on the date of the murder, resided in the county jail module where the killing occurred. Defendants also were provided with the names of every other inmate who resided in a nearby county jail module.
In discussing the danger posed to the prosecution witnesses, the Court of Appeal majority emphasized the threats by the Mexican Mafia found by the trial court, observing: “One of the witnesses was attacked and warned against testifying by an inmate aligned with the Mexican Mafia. [Defendant] Alvarado threatened a witness while he was in protective custody. While one of the witnesses was in court, someone wrote on his cell wall that he was dead.” In addition to noting that the trial court found that defendant Alvarado had threatened one of the witnesses, the Court of Appeal also observed that “both of the other witnesses received specific threats designed to dissuade them from testifying.” The majority concluded that disclosure of the witnesses’ names to the defense would further endanger the witnesses, because the Mexican Mafia then could determine who they are.
In the briefs filed in this court, defendants note that the hearings conducted by the trial court (prompted by the prosecution’s concerns for the safety of its witnesses) were held outside the presence of defendants and defense counsel, and that the transcript of that hearing was sealed. Defendants explain that under these circumstances, they are in no position to challenge the trial court’s findings regarding the alleged danger to the witnesses.
We upheld the constitutionality of the reciprocal discovery provisions of Proposition 115 in
Izazaga v. Superior Court
(1991)
Section 1054.1 provides in pertinent part: “The prosecuting attorney shall disclose to the defendant or his or her attorney all of the following . . . information, if it is in the possession of the prosecuting attorney or if the prosecuting attorney knows it to be in the possession of the investigating agencies: [10 (a) The names and addresses of persons the prosecutor intends to call at trial. . . .”
Section 1054.2 provides: “(a)(1) Except as provided in paragraph (2), no attorney may disclose or permit to be disclosed to a defendant, members of the defendant’s family, or anyone else, the address or telephone number of a victim or witness whose name is disclosed to the attorney pursuant to subdivision (a) of Section 1054.1, unless specifically permitted to do so by the court after a hearing and a showing of good cause.
“(2) Notwithstanding paragraph (1), an attorney may disclose or permit to be disclosed the address or telephone number of a victim or witness to persons emplоyed by the attorney or to persons appointed by the court to assist in the preparation of a defendant’s case if that disclosure is required for that preparation. Persons provided this information by an attorney shall be informed by the attorney that further dissemination of the information, except as provided by this section, is prohibited.
“(3) Willful violation of this subdivision by an attorney, persons employed by the attorney, or persons appointed by the court is a misdemeanor.” Section 1054.5 provides in pertinent part: “(a) No order requiring discovery shall be made in criminal cases except as provided in this chapter. . . . [1D (b) Before a party may seek court enforcement of any of the disclosures required by this chapter, the party shall make an informal request of opposing counsel for the desired material and information. If within 15 days the opposing counsel fails to provide the materials and information requested, the party may seek a court order. Upon a showing that a party has not complied with ... the informal discovery procedure provided in this subdivision, a court may make any order necessary to enforce the provisions of this chapter, including, but not limited to, immediate disclosure, contempt proceedings, delaying or prohibiting the testimony of a witness or the presentation of real evidence, continuance of the matter, or any other lawful order. . . .”
Section 1054.7 provides in pertinent part: “The disclosures required under this chapter shall be made at least 30 days prior to the trial, unless good cause is shown why a disclosure should be denied, restricted, or deferred. . . . ‘Good cause’ is limited to threats or possible danger to the safety of a victim or witness, possible loss or destruction of evidence, or possible compromise of other investigations by law enforcement. [ID Upon the request of any party, the court may permit a showing of good cause for the denial or regulation of disclosures, or any portion of that showing, to be made in camera.”
Defendants have not raised any claim under the California Constitution, and therefore we need not and do not address any state constitutional issue.

Hammon, supra,
Confrontation and cross-examination “have ancient roots”
{Greene
v.
McElroy
(1959)
This ancient right of сonfrontation took an intriguing evolutionary turn in medieval England. Beginning around the year 1290, a group of officials appointed by the King of England “began regularly to advise the king on the resolution of legal disputes which were of interest to the Crown. The Privy Council, as the group came to be called, also performed several other executive functions. By the mid-fourteenth century, when the Privy Council acted as a court, it sat in a room at Westminster ornamented with the king’s star-shaped seal. The Council-as-tribunal came to be known as the Star Chamber.”
(U.S. v. Gecas
(11th Cir. 1997)
The Star Chamber helped to maintain the Crown’s control over its enemies by adopting an inquisitorial system of criminal procedure—forgoing the use of juries, dispensing with established criminal procedure, and relying upon unidentified accusers. (Berger,
supra,
76 Minn.L.Rev. 557; see also
In re Oliver
(1948)
The colonists who emigrated from England to North America in the 17th and 18th centuries brought with them a belief in the right of confrontation. Thus, guarantees of confrontation were included within the colonial constitutions of Massachusetts, New Hampshire, North Carolina, Maryland, and Virginia, and “it appears to have been assumed that a confrontation provision would be included in the Bill of Rights that was to be added to the Constitution after ratification.”
(California v. Green
(1970)
Although the historical
underpinnings
of the confrontation clause are reasonably clear, the intended
reach
of the clause has been viewed as enigmatic. (See Berger,
supra,
76 Minn.L.Rev. at p. 562 [“Little information exists about precisely what the concept of confrontation signified in the seventeenth and eighteenth centuries in England and the colonies.”].) “[T]he Confrontation Clause comes to us on faded parchment. History seems to give us very little insight into the intended scope of the Sixth Amendment Confrontation Clause. . . .”
(California v. Green, supra,
Neither
Alford, supra,
Numerous decisions handed down in the federal courts similarly have held that where the identifying information, such as a witness’s true name and address, was deemed to be inconsequential to material issues to be contested at trial, nondisclosure was permissible on the basis that the lack of such information did not prejudice the defense. (See, e.g.,
United States
v.
Cavallaro
(2d Cir. 1977)
Judicial decisions rendered by our sister state courts and cited by the People similarly are unpersuasive. (See
State
v.
Novosel
(1980)
Our own survey of the relevant decisions rendered by our sister state courts has failed to locate a single case upholding nondisclosure at trial of the identity of a crucial prosecution witness. (See
State
v.
Baumann
(1980)
The People also urge us to find persuasive the concurring opinion of Justice White in
Smith, supra,
Although they did not raise the issue in the trial court, the People now contend that even if the trial court’s order authorizing permanent nondisclosure otherwise would be impermissible, defendants, by threatening certain witnesses, waived any constitutional right to obtain disclosure of the witnesses’ identities. For a variety of reasons, we believe this claim lacks merit.
First, there is no evidence in the record that links defendant Lopez to any threats, and thus even under the People’s theory there is no basis for finding a waiver on his behalf. Second, although evidence was introduced at the in camera hearing, from which the defense was excluded, indicating that defendant Alvarado personally had threatened a witness, Alvarado had no opportunity to contest the evidence or litigate the issue, because the People did not otherwise raise the waiver theory in the trial court. All of the cases upon which the People rely in support of their waiver theory hold that a valid waiver cannot be found absent a full hearing on the point in question. (See, e.g.,
United States
v.
Thai
(2d Cir. 1994)
Third, and finally, the trial court’s finding that the safety of the witnesses would be endangered by disclosure of their identities was based upon the premise that the danger to the witnesses was posed by the Mexican Mafia, not by the individual defendants in this case. Under this circumstance, we do not believe that the denial of disclosure can be sustained on a waiver theory.
In so concluding, we should not be understood as precluding the trial court, as this case proceeds, from reassessing any question with regard to disclosure of the identities of these witnesses. Much may have happened in the considerable time that has elapsed since the trial court’s order, or may happen between now and the time of trial, that may affect the necessity for a disclosure order. For example, the prosecution may choose not to present one or more of the witnesses, the witnesses may be unavailable, or the witnesses may choose voluntarily to disclose their names to defense counsel at a pretrial interview.
At oral argument, the People pointed out that during the past five years in Los Angeles County alone, the prosecution has filed special circumstance allegations stemming from the murder of witnesses in 25 cases, is investigating 1,600 cases of witness intimidation, and “can’t get witnesses to come forward in over 1,000 gang murders. Why? Because we cannot protect them [the witnesses].”
The use of violence and intimidation by criminal gangs to immunize themselves from the criminal justice system is by no means a recent phenomenon. (See, e.g., Invasions of Privacy: Hearings Before the Subcommittee on Administrative Practice and Procedure of the Senate Committee on the Judiciary, 89th Cong. 1st Sess., pt. 3, at p. 1157 (1965) [testimony of former United States Attorney General Nicholas Katzenbach regarding acts perpetrated by organized crime].) For example, thе Mexican Mafia, referenced throughout the findings made by the trial court in support of its nondisclosure order (ante, at pp. 1128-1129), has been described as one of the oldest prison gangs in the United States, dating back to 1957. (Lyman, *1150 Gangland: Drug Trafficking by Organized Criminals (1989) p. 53.) It is believed to exist in several states, with its membership estimated to be about 600 members. (Id., at p. 54.) In California, the Mexican Mafia has been characterized as “a highly organized, well structured, and rather sophisticated organization . . . .” (U.S. Dept. of Justice, Off. of Legal Policy, Prison Gangs, Their Extent, Nature and Impact on Prisons (1985) p. 97.) It relies upon “violent tactics to conduct business” (ibid.)', “one requirement for membership is for prospects to murder without question.” (Lyman, supra, at p. 54; see also Rohrlich & Tulsky, Gang Killings Exceed 40% of L.A. Slayings: Intimidation of Witnesses Allows Hundreds of Suspects to Walk Free. Prosecutors Try to Break the Cycle, L.A. Times (Dec. 5, 1996) p. Al, col. 4 [“More than a thousand gang killers are walking the streets of Los Angeles, Witness intimidation helps keep them there. . . . HD More and more gang killers—responsible for about 40% of Los Angeles County’s murders—remain free.”]; Corwin, Grief Galvanizes Mothers to Seek Crime Witness Aid, L.A. Times (Oct. 19, 1997) pp. Bl, col. 2, B8, cols. 1-4 [observing that gang-related murders often remain unsolved because the witnesses are afraid to come forward].)
The court’s decision in the present case is limited to addressing defendants’ legal claims regarding the propriety of the trial court’s nondisclosure order. We recognize that our decision cannot and will not alleviate the serious problem of witness intimidation.
Defendant Lopez requests that this court take judicial notice of the November 1999 California State Audit of the California Witness Protection Program. That document is subject to judicial notice under Evidence Code section 452, subdivision (c), and we grant his request. (Evid. Code, § 459.)
