Opinion
BIRD, C. J.
— This court must decide what is the proper remedy for an accused when his constitutional right to counsel has been denied by the actions of an undercover police officer who poses as a codefendant and attends the confidential attorney-client conferences of the accused.
I
On August 7, 1977, approximately 50 people, including all of the petitioners, participated in a “sit-in” near the site of the Pacific Gas and Electric Company’s (hereafter, P.G. & E.) Diablo Canyon nuclear facility to demonstrate their opposition to the use of nuclear power to generate energy. The petitioners were arrested and each was charged with two counts of trespassing. (Pen. Code, §§ 602, subd. (k) and 602, subd. (n).) All of the petitioners, except U’ren and Rosenburg, were also charged with one count of unlawful assembly. (Pen. Code, § 409.)
On October 4, 1977, before the date set for trial of these cases, petitioners learned that one of the codefendants was an undercover police officer. They moved to dismiss on the grounds that presence of the agent at confidential attorney-client meetings had deprived them of their rights to the effective assistance of counsel and due process of law.
At the hearing on the motion the following testimony was received:
*746Several weeks prior to the, demonstration, advertisements were placed in local newspapers inviting the public to attend meetings at which opposition to the Diablo Canyon nuclear facility and plans for the demonstration were to be discussed. The meetings were sponsored by a national organization, the Abalone Alliance, and a local group, People Generating Energy, both opposed to the use of nuclear power to generate energy.1
Two officers, Detective C. D. Smith of the Santa Barbara County Sheriff’s Department and reserve Deputy Sheriff James Lee of the San Luis Obispo County Sheriff’s Department, were assigned by their respective employers to attend the meetings in an undercover capacity in order to learn more about the group, the plans for the demonstration, and to ascertain whether there would be any violence at the demonstration.2
Both officers became intimately involved with the group and attended numerous meetings at which plans for the demonstration were discussed. At all of these meetings it was strongly emphasized that the group was committed to nonviolence and at none of these meetings was there any indication that the demonstration would be anything other than peaceful and nonviolent. The two officers also attended an all-day “nonviolent training” session, attendance at which was required for those who would actually participate in the sit-in. At this meeting the participants engaged in various role-playing sessions designed to teach the participants how to react nonviolently to stress situations which might be encountered with police officers.3
Prior to the demonstration, representatives of the group asked to meet with members of the San Luis Obispo County Sheriff’s Department and representatives of P.G. & E. Two meetings were held at which the representatives of the group told the sheriff’s department and P.G. & E. officials of the plans for the demonstration, including the time it was to be *747held, the route to be taken and the number of people to be involved.4 They also stressed the group’s commitment to nonviolent demonstration.
On August 3, 1977, at the request of the county district attorney’s office, Judge Conklin, Presiding Judge of the Municipal Court for the San Luis Obispo Judicial District, met in the district attorney’s office with several deputy district attorneys and sheriff’s officers. At this meeting the planned demonstration was discussed. Judge Conklin was informed that there would be violations of certain provisions of the Penal Code. Decisions were made to arraign the arrestees on the same day of the arrests in the county jail auditorium and to release all of them without bail whether or not they signed O.R. release forms.
On August 7th, the demonstration occurred as planned. About 50 people, including petitioners and Officers Lee and Smith, accompanied by approximately 75 to 100 news media people, crossed over two fences and entered an access road maintained by P. G. & E.5 The group proceeded on the access road to a point about one-half mile from the main entrance and six and one-half miles from the power plant. After warnings to disperse were given, the demonstrators were arrested.6 The arrestees were transported to the county jail, where petitioners and Officer Lee were booked and charged.7
Attorneys Haynes and Stone, having been asked to represent the group, arrived at the jail to consult with the arrestees, including Officer Lee. Officer Lee was present at this confidential attorney-client conference and testified that he was sure defense strategy was discussed but was not paying close attention.
*748Judge Conklin arrived at the jail at 6 p.m. for the arraignments. However, the proceeding did not begin until 8:30 p.m. While he was waiting to begin, he had numerous discussions about the cases with members of the sheriff’s department and the district attorney’s office.8 During some of the discussions, defense attorneys were present; during others, they were not. Judge Conklin learned that evening that some of those arrested were undercover police officers. Defense counsel were not present when he was told this information and he did not inform them that some of their clients might be undercover officers.
Detective Doug Mansfield, Officer Lee’s immediate supervisor, testified that he informed Deputy District Attorney Shea the day after the demonstration that defendant Lee was a police officer. Shea did not inform defense counsel.
Officer Lee continued to pose as a codefendant with petitioners and as a client of the firm of Haynes and Olpin. As such, he attended numerous confidential attorney-client conferences, all of which “went into detail” about various aspects of the cases, including defense strategy. Lee testified he participated in discussions “about the defense in general” but did not recall discussing his “personal defense.”
On one occasion Attorney Stone asked for volunteers to accompany her to inspect the site of the demonstration. Lee was one of two defendants who volunteered and thereby became involved in the strategy discussion occurring at the scene. On another occasion, defense counsel asked that one of the group draw a map of that area. Lee again volunteered to do so. He prepared a detailed map of the fences and gates on the site, but failed to show the presence of an opened gate at a key location. Officer Lee testified that he had not intentionally omitted the gate and did not intend to mislead the petitioners.9 Lee admitted, however, that prior to drawing the map, he had inspected the site with his superiors.
Attorney Stone testified that she inspected the site after Lee had given her the map but failed to notice the presence of the gate. She testified that *749the inspection had consisted of being driven though the site of the demonstration by P.G. & E. officials. She testified that although P.G. & E. had later furnished defense attorneys with maps of the area, these were geographical maps and did not show any fences or gates. She gave Lee’s map to the present attorney in the case when he substituted as defense counsel.
From the time of the arrest on August 7th to October 4th, Lee reported to Detective Doug Mansfield or Captain Wood. Most of the information that Lee communicated to his superiors was communicated orally, either by telephone or in person. Lee filed only one written report during that period. Lee’s superiors testified that, although they could not remember what information Lee gave them, they were sure he gave them no information about defense strategy. Lee stated that he informed his superiors that the defense was to become more “political.” All three officers testified that they did not discuss Lee’s reports with any members of the district attorney’s office.
The sheriff’s department justification for maintaining Lee in his undercover assignment after the arrests was to gain information about possible infiltration of the group by terrorists or to learn of plans for future violent demonstrations by the group. The officers testified that, although the group had informed them that they planned another demonstration sometime in January 1978, there was no indication of any ■ terrorist infiltration or advocacy of violence by any member of the group.
At one point Officer Lee decided he would enter a plea of nolo contendere on October 4th and remove himself from the court proceedings. He mentioned these plans on October 1st to some of the defendants but did not discuss them with any of the attorneys. Shortly before October 4th, however, the group decided to substitute new counsel and pursue a more “political” defense. Lee then decided not to enter the plea because, he claimed, he was not sure of the “legal ramifications” of entering a plea while represented by the new attorneys. He admitted that he had no intention of discussing these “legal ramifications” with new counsel; he intended instead to talk to Detective Mansfield.
Sometime during October 4th, Judge Conklin informed new counsel that one of his clients was an undercover police officer. The next day an article appeared in the local paper revealing Lee’s true identity.
*750The new attorney, Frishman, found that after the undercover status of Officer Lee was revealed, petitioners’ actions were “characterized, if you can use the word, by paranoia concerning the use of informants by the state.” Whereas prior to the revelation petitioners very actively participated in meetings with their former counsel, since that time they “have been most reluctant to speak out at defense meetings.” The petitioners have become veiy distrustful of one another and have even questioned the identity of Frishman’s law student assistant, fearing that there may be other undisclosed, undercover agents still amongst them. Attorney Frishman concluded that he had “found that the defendants’ ability to proceed with their defense and to assist [him] in preparing their defense has been substantially impaired [and that] the impairment has been caused by the use of informants [¿7c] in this case.”
The trial court denied the motion to dismiss on the grounds that there had been no evidence to show that information gained by Officer Lee had been transmitted to the prosecution. However, the court ordered “that the people may not use any evidence obtained by Mr. Lee or that was derived from his presence at any meetings between counsel, either previous counsel, present counsel or future counsel, if such be the case, nor the fruits thereof may not be used in evidence, and that they may not in rebuttal to any evidence put forth by the defendants, use any evidence whatsoever unless the prosecution can first prove beyond a reasonable doubt that such evidence was obtained independently of the activities of Mr. Lee.”
This writ petition followed.
II
The right to counsel is guaranteed to a defendant in a criminal case by both the Sixth Amendment to the United States Constitution and article I, section 15 of the California Constitution. This right' is a “fundamental constitutional right, which has been carefully guarded by the courts of this state.” (In re James (1952) 38 Cal.2d 302, 310 [240 P.2d 596]; People v. Douglas (1964) 61 Cal.2d 430, 434 [38 Cal.Rptr. 884, 392 P.2d 964]; People v. Carter (1967) 66 Cal.2d 666, 669 [58 Cal.Rptr. 614, 427 P.2d 214].) “Meaningfully applied, the right to counsel includes the opportunity to receive ‘effective aid [of counsel] in the preparation and trial of the case.’ [Citations omitted.]” (People v. Douglas, supra, 61 Cal.2d at p. 434; People v. Carter, supra, 66 Cal.2d at p. 669.)
*751In order to insure that a criminal accused receives the effective assistance of counsel, the constitutional guarantee imposes a duty on defense attorneys “to investigate carefully all defenses of fact and of law that may be available to the defendant. . . .” (People v. Ibarra (1963) 60 Cal.2d 460, 464 [34 Cal.Rptr. 863, 386 P.2d 487].) This duty to investigate requires that counsel gather as much information as possible about the case, including facts concerning the acts charged, possible defenses, and the accused’s background and prior record. A primary source of such information is the accused himself. Often, whether guilty or innocent of the offense charged, the accused knows facts pertinent to his defense which may tend to incriminate or embarass him. However, “[a]s a practical matter, if the client knows that damaging-information could more readily be obtained from the attorney following disclosure than from himself in the absence of disclosure, the client would be reluctant to confide in his lawyer and it would be difficult to obtain fully informed legal advice.” (Fisher v. United States (1976) 425 U.S. 391, 403 [48 L.Ed.2d 39, 51, 96 S.Ct. 1569].)  Thus, if an accused is to derive the full benefits of his right to counsel, he must have the assurance of confidentiality and privacy of communication with his attorney.
It is for this reason that the courts have recognized that the right to counsel guaranteed by the California Constitution embodies the right to communicate in absolute privacy with one’s attorney. Former article I, section 13 (now art. I, § 15) of the California Constitution “unquestionably was adopted to secure to the accused person all the benefits which may flow from the employment of counsel to conduct his defense. To afford him those benefits it is essential that he should be allowed to consult with his counsel, not only during the actual trial, but prior thereto, in order to prepare for his defense. ... It is equally essential to the enjoyment of this constitutional guarantee that the accused should have the right to a private consultation with his counsel. ... ‘If the right " of defense exists, it includes and carries with it the right of such freedom of action as is essential and necessaiy to make such defense complete. In fact, there can be no such thing as a legal trial, unless both parties are allowed a reasonable opportunity to prepare to vindicate their rights. . . . It therefore necessarily follows that it is the absolute right of parties charged with crime to confer privately with their attorneys. . . .’ ” (In re Rider (1920) 50 Cal.App. 797, 799-800 [195 P. 965]; accord In re Jordan (1972) 7 Cal.3d 930, 941 [103 Cal.Rptr. 849, 500 P.2d 873]; Cornell v. Superior Court (1959) 52 Cal.2d 99, 102-103 [338 P.2d 447, 72 A.L.R.2d 1116]; In re Qualls (1943) 58 Cal.App.2d 330, 331 [136 P.2d 341]; In re Snyder (1923) 62 Cal.App. 697, 699-700 [217 P. 777].)
*752The right to counsel, which embodies the right to private consultation with counsel, is violated when a state agent is present at confidential attorney-client conferences. (In re Rider, supra, 50 Cal.App. 797 [the constitutional right to counsel is denied when a juvenile court ward, in custody at juvenile hall, was not permitted to consult with her attorney except in the presence of the superintendent or his agent]; In re Snyder, supra, 62 Cal.App. 697 and In re Qualls, supra, 58 Cal.App.2d 330 [the right to counsel is violated by prison regulations requiring attorney-client conversations to take place through a wire mesh screen and in the presence of other attorneys and their clients, who could overhear nearby conversations]; see also In re Jordan, supra, 1 Cal.3d 930 [striking down prison regulations permitting prison officials to read attorney-client correspondence].)
In addition to the constitutional right to consult privately with counsel, there are numerous legislative enactments designed to protect the confidentiality of attorney-client communications. For example, Business and Professions Code' section 6068, subdivision (e) states: “It is the duty of an attorney: ...(e) To maintain inviolate the confidence, and at every peril to himself to preserve the secrets, of his client.” Evidence Code section 954 grants a client “a privilege to refuse to disclose, and to prevent another from disclosing, a confidential communication between client and lawyer. ...” Penal Code section 636 makes it a felony for anyone to eavesdrop or record “a conversation” between “a person who is in the physical custody of a law enforcement officer . . . and such person’s attorney. ...” As this court has noted, “the protection of [client] confidences and secrets is not a rule of mere professional conduct, but instead involves public policies of paramount importance which are reflected in numerous statutes.” (In re Jordan, supra, 7 Cal.3d at pp. 940-941.)
Respondent contends that these principles do not apply to the present case for several reasons. First, it argues, the intrusion of a state agent into confidential attorney-client communications does, not violate the right to counsel if the purpose for the intrusion is to detect future crimes rather than to discover defense strategy. This argument has been previously rejected by our courts. In In re Snyder, supra, and In re Jordan, supra, the state asserted that the intrusions in those cases10 were justifiable to detect *753present crime, prevent future crime, and protect jail or prison security. In each case the court held that notwithstanding the duty of state officials to protect prison security, they must do so by means that do not interfere with the right of the accused to privacy' of communication with counsel. “[W]e all realize that official duty, grave and important as it is, must be performed in subordination to the constitutional rights of others.” (In re Snyder, supra, 62 Cal.App. at pp. 701-702; see also In re Jordan, supra, 7 Cal.3d at p. 939.)11
It is irrelevant to the reasons underlying the guarantee of privacy of communication between client and attorney that the state is intruding for one purpose rather than for another. “[T]he purpose and necessities of the relation between a client and his attorney require, in many cases, on the part of the client, the fullest and freest disclosure to the attorney of the client’s objects, motives, and actions.” (In re Jordan, supra, 7 Cal.3d at p. 940.) The chilling effect on full and free disclosure by a client would be the same, whatever the state’s asserted purpose for intruding. The intruding state agent by his presence will be privy to confidential communications. Aware of this possibility, a client will be constrained in discussing his case freely with his attorney.
Respondent next contends that petitioners’ discussions with their attorneys were not confidential because they openly discussed their cases in the presence of other defendants.  However, Evidence Code section 952 and the accompanying comment by the Law Revision Commission indicate that a client’s communications with his attorney do not lose their confidential nature simply because they are made in the presence of joint clients. Section 952 provides that a “confidential communication between client and lawyer” includes information disclosed by a client to his attorney in the presence of third persons “who are present to further the interest of the client in the consultation or ... to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted. . . .” The Law Revision Commission comments to this section state that “a communication to a lawyer is nonetheless confidential even *754though it is made in the presence of another person — such as a spouse, parent, business associate, or joint client — who is present to further the interest of the client. . .  Thus, the fact that the petitioners discussed their defenses with joint counsel in a conference-type setting rather than in a one-on-one session does not diminish their right of confidentiality.12
Finally, respondent relies on a recent decision by the United States Supreme Court, Weatherford v. Bursey (1977) 429 U.S. 545 [51 L.Ed.2d 30, 97 S.Ct. 837]. In that case, both a defendant (Bursey) and an undercover agent (Weatherford) were arrested and prosecuted for vandalizing the offices of a local draft board. Each man was released on bond and retained a separate attorney. On two occasions the defendant Bursey and his attorney asked Weatherford to confer with them “in an effort to obtain [from Weatherford] information, ideas or suggestions as to [Bursey’s] defense.” Weatherford did accept these invitations but did not discuss with or pass on to his superiors or to the prosecution any details or information regarding Bursey’s trial plans, strategy, or anything having to do with the criminal action pending against Bursey. (Id., at p. 548 [51 L.Ed.2d at p. 35].) Weatherford remained in his undercover role until he “lost some of his effectiveness as an agent in the weeks preceding trial because he had been seen in the company of police officers. . . .” (Id., at p. 549 [51 L.Ed.2d at p. 36].) Weatherford was called as a witness at Bursey’s trial and he testified only to events occurring prior to their arrests. Following his conviction, Bursey filed suit against Weatherford and his superiors under 42 United States Code, section 1983, alleging he had been deprived by them of his right to counsel under the Sixth and Fourteenth Amendments to the United States Constitution. A divided Supreme Court upheld the trial court’s judgment in favor of Weather-ford.
It is by no means clear that Weatherford would support respondent’s position. Throughout the Weatherford opinion, the Supreme Court relied on factors which are significantly different from those in the present case:
*755(1) Weatherford retained separate counsel from Bursey, while Officer Lee retained the same attorney as petitioners.
(2) Weatherford attended the attorney-client conferences at the specific request of Bursey and for Bursey’s sole benefit. Weatherford was not “instructed to intrude on the lawyer-client relationship” and had not “assumed for himself that task.” (Id., at p. 557 [51 L.Ed.2d at p. 41].) In this case, Officer Lee was instructed by his superiors to attend the attorney-client meetings. He was not specifically requested to attend by the defendants. His attendance was, ostensibly, as much for his personal benefit as for the benefit of the others.
(3) Weatherford communicated no information about the defense to his superiors. However, in the present case Officer Lee told his superiors that there was to be a “political” defense and that the defendants would attempt to postpone the trial.13
(4) In Weatherford, no “specific prejudice to the defendant’s preparation for or conduct of trial [was] demonstrated or otherwise threatened.” (Id., at p. 550 [51 L.Ed.2d at p. 37].) In this case, there was evidence that since the disclosure of Lee’s undercover role, petitioners had become reluctant to cooperate fully with their attorney.
Not only is Weatherford inapposite, it cannot be used as authority to justify the police action here since the right to privacy of communication between an accused and his attorney has consistently been grounded on California law. (Cf. ante, at pp. 752-753.) The first California case to expressly recognize that right was decided more than a decade before Powell v. Alabama (1932) 287 U.S. 45 [77 L.Ed. 158, 53 S.Ct. 55, 84 A.L.R. 527] made the Sixth Amendment’s right to counsel applicable to the states in capital cases. (Compare In re Rider (1920) 50 Cal.App. 797 [195 P. 965]; In re Snyder (1923) 62 Cal.App. 697 [217 P. 777].) Moreover, the decisions in this area since Powell have relied on California law and have not referred to the federal Constitution.14 (In re Jordan, supra, 1 Cal.3d 930; In re Qualls, supra, 58 Cal.App.2d 330.)
*756The right under California law to communicate privately with counsel was violated when a government agent in an undercover capacity was present at confidential attorney-client meetings.15
Ill
Next, this court must determine what relief should be given. Petitioners contend that an exclusionary remedy, such as the trial court applied in this case (cf. ante, at p. 750), is inadequate to protect their rights and will not deter the state from such unlawful intrusions in the future. This court agrees.
Whether or not the prosecution has directly gained any confidential information which may be subject to suppression, the prosecution in this case has been aided by its agent’s conduct. Petitioners have been prejudiced in their ability to prepare their defense. They no longer feel they can freely, candidly, and with complete confidence discuss their case with their attorney. Petitioners’ attorney testified that the discovery of the undercover agent’s true identity resulted in a refusal by his clients to offer suggestions or criticize any aspect of the conduct of the cases. Distrustful of each other and fearing that any one of them might also be an undercover police officer, the petitioners have even questioned the true identity of defense counsel’s law student assistant. This lack of cooperation, which resulted solely from the intrusion by law enforcement officers in the attorney-client relationship, has resulted in counsel’s inability to prepare adequately for trial. To allow these cases to proceed to trial under these circumstances would be contrary to basic notions of fair play and simple justice.
*757Furthermore, the enforcement of an exclusionary rule would involve exceedingly difficult problems of proof for the aggrieved client. Subtle forms of prejudice are nearly impossible to isolate. Consider the prosecution witnesses who learn of some of the illegally obtained information. Even if the witnesses do not divulge the information to the prosecutor, the witnesses will be “in a position to formulate in advance answers to anticipated questions, and even to shade their testimony to meet expected defenses.” (Weatherford v. Bursey, supra, 429 U.S. at pp. 561, 564 [51 L.Ed.2d at pp. 43, 45] (dis. opn. of Marshall, J.).) If, to use Justice Marshall’s example, the undercover officer learned that the accused would use an entrapment defense, he could plan his testimony so as to minimize his own role and emphasize the accused’s predisposition. (Ibid., fn. 1 [51 L.Ed.2d at p. 45].) The accused, on the other hand, “would have . . . little time to reconstruct in his mind [the officer’s] role in the decision to commit the crime once [the officer] testified he was the state agent.” (Ibid.)
Even the blatant use of illegally obtained information will be difficult to prove. As Justice Marshall points out, “[p]roving that an informer reported to the prosecution on defense strategy will [seldom be possible], not only because such proof requires an informer or prosecutor to admit his own wrongdoing (and open the door to damage suits and attacks on convictions), but also because an informer’s failure to make a report after overhearing a lawyer-client session oftentimes can be an effective means of communicating to the prosecutor that nothing surprising was uncovered.” (Id., at p. 565 [51 L.Ed.2d at p. 46].)16
*758Finally, enforcement of an exclusionary remedy would place an accused in a Catch-22 situation, because in order to protect his confidences, the client would have to permit them to be re-violated. For a trial court to intelligently pass upon the question whether the prosecution his met its burden of showing that certain preferred evidence is not a fruit of or tainted by the illegally obtained information, the court would have to be advised — by competent evidence on the record — as to the illegally obtained information. It would be unreasonable for a judge to rule on whether the tendered evidence is a fruit of illegally obtained information without knowing the substance of the illegal information, i.e., what agent Lee observed or overheard. Yet, advising the court on the record of the nature of the conversation or the illegally obtained information requires a re-disclosure of the confidential communication.17 That re-disclosure must be made not only to the trial court, but also to the prosecutor who would thereby learn the defense strategy, if he had not learned it earlier.18 Clearly, an exclusionary remedy would be illusoiy, since the client could not be assured that he has been insulated from harm without requiring him to reopen the wound his adversary inflicted upon him in the first place.19
*759The exclusionary remedy is also inadequate since there would be no incentive for state agents to refrain from such violations. Even when the illegality is discovered, the state would merely prove its case by the use of other, untainted evidence. The prosecution would proceed as if the unlawful conduct had not occurred.
Respondents rely for their exclusionary remedy on Wilson v. Superior Court (1977) 70 Cal.App.3d 751 [139 Cal.Rptr. 61]. In that case, police officers surreptitiously tape-récorded á conversation in jail between an inmate awaiting trial and his attorney. The Court of Appeal found this to be “an outrageous violation of [the accused’s] most fundamental constitutional rights . . . [that] poses a potential threat to the rights of each of us.” (Id., at p. 758.) However, it held that the prosecution could continue if there remained “sufficient evidence to maintain a prosecution which is neither derived from nor tainted by the illegal intrusion into the attorney-client relationship. . . . The burden of such proof lies with the People. . . .” (Id., at p. 759.) The prosecutor would not be allowed to rebut any defense evidence nor cross-examine any defense witness “except to impeach them with appropriate prior felony convictions, knowledge of which the People would gain from their own files, unless the People, outside the presence of the jury, first demonstrate to the satisfaction of the trial court, beyond a reasonable doubt [citation], that the evidence they seek to adduce derives in no way from the tape.” (Id., at p. 760.)
The court in Wilson did not further explain its rationale for adopting an exclusionary rule, nor did it address any of the problems inherent in such a remedy. (Ante, at pp. 756-759.) Wilson is therefore unpersuasive on this issue.
An exclusionary remedy is not only ineffective as a deterrent, but the problems of proof inherent in the remedy when applied to violations of the right to counsel would be inadequate to assure that the prosecution does not benefit from the illegality.
IV
The intrusion, through trickery, of the law enforcement agent in the confidential attorney-client conferences of petitioners cannot be con*760doned. The right to confer privately with one’s attorney is “one of the fundamental rights guaranteed by the American criminal law — a right that no legislature or court can ignore or violate.” (In re Rider, supra, 50 Cal.App. at p. 799.) The only effective remedy is the dismissal of the underlying charges. Therefore, it is ordered that a writ of prohibition be issued as prayed.
Tobriner, J., Mosk, J., and Newman, J., concurred.

 Petitioners are members of either the national or the local organizations.

 Although Lee knew Smith was an undercover officer, Smith was not aware that Lee was a peace officer.

 The only indication of the possibility of violence was'attributed to Officer Lee. At the all-day training session he stated that he was not sure he would react nonviolently to police officers. Also, immediately prior to the demonstration, members of the group discovered that Officer Lee was .carrying a large knife. He was persuaded to disarm himself.

 The group had originally intended to march directly to the front gate of the RG. & E. property. Officer Lee was strongly opposed to such a direct route and encouraged the group to plan “circumventing” routes. He also adamantly opposed the group’s decision to inform the sheriff’s department of the plans for the demonstration. He stated that the group was giving the sheriff’s department too much information.

 An additional 12 to 15 group members accompanied the demonstrators. According to Officer Smith’s testimony, these members were acting as monitors for the demonstrators and their purpose was “to be like buffers, to keep outside agitators from provoking or causing violence or creating a disturbance.”

 The officers involved in the arrests testified that the demonstration had been very peacefúl and nonviolent and that no problems had been encountered in effectuating the arrests.

 Officer Smith was released shortly after arriving at the jail and was not involved in any of the events which occurred thereafter.

 Judge Conklin testified that at no time did he discuss the merits of the cases with the prosecutors.

 The presence or absence of the opened gate could have been crucial at the trial of petitioners in the case of In re Johnson, (Post, at p. 769[157 Cal.Rptr. 674, 598 P.2d 834].) Had they known of the gate, they would have been able to argue that the area on which the demonstration took place was not fully enclosed or posted, as required by Penal Code section 602, subdivision (k).

 In Snyder, the intrusion was a wire mesh screen between attorney and client, which prevented papers from being passed back and forth and made reading of documents through the screen difficult. In Jordan, the intrusion consisted of state agents reading mail from attorneys to prisoners or prisoners to attorneys.

 See also cases collected in Annotation, Scope and Extent, and Remedy or Sanctions for Infringement, of Accused’s Right to Communicate With His Attorney (1966) 5 A.L.R.3d 1360-1399, where, at page 1365, it is said: “One class of cases in which courts have had little difficulty in trying to strike a balance between liberty and authority involves ‘eavesdropping’ on counsel-client conversations, either by electronic devices installed in conference rooms or by means of paid informers who gain access to the privileged communications cf the defense. In such instances, courts have not hesitated to rule as unconstitutional and in violation of the attorney-client privilege such underhanded methods of the prosecution.”

 Respondent attempts to equate the actions of Undercover Agent Lee with a codefendant who has attended and participated in attorney-client meetings but who subsequently decides to cooperate with the prosecution. It is argued that petitioners must suffer the consequences of their misplaced confidences. However, it is one thing for an individual to be “betrayed” by an acquaintance or a private person with whom he has associated. It is another for the government deliberately to send out agents to do to its citizens by trickery what it may not do to them directly. “The difference between the risk of faithlessness that we all run when we choose our friends and the risk of faithlessness that we run when government foists a multiplying army of bribed informers on us may well be a matter of degree; but of such degrees is liberty or its destruction engineered.” (Amsterdam, Perspectives on the Fourth Amendment (1974) 58 Minn. L.Rev. 349, 407.)

 Moreover, Officer Lee, unlike Agent Weatherford, actively participated in defense planning, including the preparation of a (faulty) map of the arrest site.

 The dissent by my colleague, Justice Clark, inaccurately asserts that this court “ultimately shift[s] ground” from the federal to the state Constitution in reaching its decision. Quite the contrary, this decision flows directly and exclusively from principles of California law — constitutional, decisional, and statutory — all of which predated Weather-ford. (In re Jordan, supra, 7 Cal.3d 930; Cornell v. Superior Court, supra, 52 Cal.2d 99; In *756re Qualls, supra, 58 Cal.App.2d 330; In re Snyder, supra, 62 Cal.App. 697; In re Rider, supra, 50 Cal.App. 797; Bus. & Prof. Code, § 6068, subd. (e); Evid. Code, §§ 915, 952, 954; Pen. Code, § 636.) The dissent somehow manages to reach its conclusions without dealing with, or even mentioning, any of this dispositive California law.
Even if this case were to be decided under federal law, the dissent’s conclusion that there was no violation of the right to counsel would not be sustained. There is a significant legal distinction between an undercover agent who retains his own separate counsel (Weatherford) and one who retains the same attorney as his unsuspecting codefendants (Barber et al.); between an agent who attends an attorney-client conference at the specific invitation of his codefendant (Weatherford) and one who attends under the instruction of his government (Barber)-, between an agent who seeks a separate trial from his codefendants (Weatherford) and one who seeks a joint trial (Barber)-, and between an undercover agent who merely gives information, ideas, and suggestions to defense counsel (Weatherford) and one who volunteers to draw (inaccurately) maps for counsel and who reports the nature of the defense to his superiors.

 In view of this conclusion, it is not necessary to decide whether petitioners’ rights to due process of law and against self-incrimination have also been violated.

 My colleague, Justice Manuel, asserts an aggrieved client will have no problems of proof because under an exclusionary rule it would be the prosecution that must prove an independent source beyond a reasonable doubt for its evidence. However, this contention overlooks the difficulties and dilemmas facing a client and his lawyer. If the accused has to put forward evidence of his own in order to attack or impeach the prosecution’s claim of lack of taint, then the accused is forced to give up his Fifth Amendment rights. Moreover, this argument ignores the real fact that many forms of prejudice do not logically lend themselves to an exclusionary remedy.
The concurring and dissenting opinion further suggests that “[ajbsent jeopardy, violations of constitutional rights do not gain an accused immunity from punishment.” That is not quite the law. Dismissal of a pending prosecution is the well-established remedy for a number of constitutional violations, including a violation of the right to a speedy trial. (See, esp., Strunk v. United States (1973) 412 U.S. 434 [37 L.Ed.2d 56, 93 S.Ct. 2260].) This is true even if there has been no affirmative showing of prejudice to the accused. (See Moore v. Arizona (1973) 414 U.S. 25 [38 L.Ed.2d 183, 94 S.Ct. 188].) Similarly, a dismissal is required upon the failure of the prosecution to disclose or remain in contact with an informant who merely might give exculpatory evidence on the issue of guilt or innocence. (See, e.g., Eleazer v. Superior Court (1970) 1 Cal.3d 847 [83 Cal.Rptr. 586, 464 P.2d 42].) Moreover, one Court of Appeal specifically held that dismissal, rather than the exclusion of evidence, was the appropriate remedy where the prosecution *758interferred in the attorney-client relationship. (People v. Moore (1976) 57 Cal.App.3d 437 [129 Cal.Rptr. 279].)

 Requiring such a re-disclosure would also be in direct violation of Evidence Code, section 915, which provides in pertinent part: “(a) Subject to subdivision (b), the presiding officer may not require disclosure of information claimed to be privileged under this division in order to rule on the claim of privilege.” The Law Revision Commission comments to this section state: “Subdivision (a) states the general rule that revelation of the information asserted to be privileged may not be compelled in order to determine whether or not it is privileged. This codifies existing law. [Citations.]”

 Indeed, it seems a patent violation of an accused’s right against self-incrimination to require him to elicit evidence of defense strategy in this manner in order to protect his right to a trial free from taint.
Moreover, consider the dilemma of a client who hears an undercover agent testify falsely on what defense strategy was discussed. Would the client take the witness stand to impeach the agent by recounting the true defense strategy?

 Neither of the dissenting opinions squarely meets this central issue. How may a meaningful exclusionary remedy be adequately enforced without violating Evidence Code section 915 or the privilege against self-incrimination and without reviolating the attorney-client privilege? This problem is carefully avoided by the dissenters.
Instead, the dissent by Justice Clark erroneously suggests that in Weatherford the Supreme Court rejected a “reversal per se” sanction for this type of violation of the right to counsel. That suggestion is fallacious, since the issue of remedy for a violation of the right to counsel in a criminal case was not before the court in Weatherford. Rather, the court found there had been no violation of the federal Constitution at all. It never reached the question whether, had there been a violation, an exclusionary remedy was preferable to a dismissal. Indeed, since the Weatherford case was a civil suit brought after the defendant’s conviction was final, the question of the appropriate remedy in criminal cases would not have come before the court even if it had found a violation of the Sixth Amendment. Thus, Weatherford simply is not informative on the question of what remedy is appropriate when a violation of the Constitution has in fact occurred.
