Opinion
ROGERS, C. J.
The central issue in this case is whether a prosecutor’s intrusion into communications between a defendant and his attorney that are subject to the attorney-client privilege requires the dismissal of the criminal charges against the defendant. The defendant, Patrick J. Lenarz, was charged in three infor-mations, each of which charged the defendant with risk of injury to a child in violation of General Statutes § 53-21 (a) (1) and (2), and sexual assault in the fourth degree in violation of General Statutes § 53a-73a (a) (1) (A). Before trial, the prosecutor came into possession of and read certain written materials belonging to the defendant that were subject to the attorney-client privilege. Upon learning this fact, the defendant filed a motion to dismiss the charges against him, which the trial court denied. After a trial, the jury returned a verdict of guilty on one count of risk of injury to a child in violation of § 53-21 (a) (1). The jury found the defendant not guilty of all of the remaining charges, and the trial court rendered judgments in accordance with the verdict. The defendant then appealed,1 claiming that the trial court improperly denied his motion to dismiss.2 We conclude that, because the case is irreversibly tainted by the prosecutor’s intrusion into the privileged communications, the only available appropriate remedy is dismissal of the charge of which he was convicted. Accordingly, we reverse the judgment of conviction.
[420]*420The record reveals the following relevant facts and procedural history.3 The defendant was charged in two informations, each alleging two counts of risk of injury to a child and one count of sexual assault in the fourth degree, in connection with the defendant’s alleged conduct toward two children at a karate school in the town of Granby, where the defendant was an instructor (respectively, Docket Nos. H12M-CR-03-128673-S and H12M-CR-03-129740-S; collectively, Granby cases). Thereafter, the defendant was charged in a third information with two counts of risk of injury to a child and one count of sexual assault in the fourth degree in connection with an incident involving a child at the defendant’s residence in Simsbury (Simsbury case). Ultimately, all three cases were consolidated for trial.
As part of its investigation into the incident that formed the basis for the charges in the Simsbury case, the Simsbury police department obtained a search warrant for the defendant’s residence. During the search, which took place on November 17, 2004, the police seized a computer, which they sent to the Connecticut Forensic Science Laboratory (state laboratory) to be forensically searched. The next day, at the defendant’s arraignment, defense counsel advised the trial court, Scheinblum, J., that certain materials in the computer were subject to the attorney-client privilege and asked the court to fashion orders to protect the defendant’s rights. The court ordered that “any communications from [defense counsel] to [the defendant] or from [the defendant] to [defense counsel] remain unpublished [and] unread.” The court entered a similar order with [421]*421respect to communications to and from the defendant’s private investigator.
During its examination of the defendant’s computer, the state laboratory discovered voluminous written materials containing detailed discussions of the defendant’s trial strategy in the Granby cases. The state laboratory read and copied much of this material and transmitted it to the Simsbury police department along with its report. In turn, the Simsbury police department forwarded the materials and the report to the prosecutor. At a meeting between the prosecutor and defense counsel some time in September, 2005, the prosecutor provided defense counsel with a. copy of the materials that he had received from the Simsbury police department. Defense counsel immediately requested a meeting with Judge Scheinblum in chambers, at which he advised the judge that the prosecutor had read materials that were subject to the attorney-client privilege. The trial court then ordered the police departments in Sims-bury and Granby and the prosecutor to turn over any “questionable material” in their possession to the court and ordered that the material be placed under seal. Although it is unclear from the record how long the prosecutor had been in possession of the privileged communications before the September, 2005 meeting, defense counsel represented at a hearing on a motion to suppress the materials seized under the search warrant that the prosecutor had had the materials for six weeks, and the prosecutor did not dispute this claim.4
[422]*422The defendant then filed a motion to dismiss the informations in the Granby cases5 on the ground that the state had intentionally invaded the attorney-client privilege, thereby depriving the defendant of his right to counsel under the sixth amendment to the United States constitution.6 The defendant argued that the intrusion had resulted in substantial prejudice to him because the privileged communications contained detailed trial strategy. The state admitted that the prosecutor had read all of the materials and did not dispute that the documents contained trial strategy, but claimed that, because the prosecutor had not conducted any additional investigation and had not interviewed any additional witnesses as a result of reading the materials, the defendant had suffered no prejudice. In addition, the state claimed that the prosecutor had not wilfully violated the attorney-client privilege, but had obtained the privileged materials in good faith. Accordingly, the state argued that the appropriate remedy for its allegedly unintentional invasion of the attorney-client privilege was the suppression of the privileged communications.
The trial court, Olear, J., issued a memorandum of decision on the defendant’s motion to dismiss in which it concluded that, because the privileged communications had not been in the form of letters or e-mails between the defendant and his attorney, the state laboratory and the prosecutor had not intentionally violated Judge Scheinblum’s order prohibiting the state from publishing or reading any privileged communications. [423]*423Nevertheless, because the defendant had testified at an ex parte hearing before the trial court that he had in fact delivered the materials to his attorney and had submitted an affidavit to that effect under seal, the trial court concluded that the materials were subject to the attorney-client privilege. Accordingly, the trial court ordered a hearing to determine whether the defendant had been prejudiced by the state’s unintentional invasion of the attorney-client privilege and, if so, what was the appropriate remedy.
After an evidentiary hearing, the trial court denied the defendant’s motion to dismiss. The court concluded that, because the Simsbury police department had not shared the privileged information with the Granby police department, the defendant had suffered no prejudice in the Granby cases. To ensure a fair trial, however, the trial court ordered that the Simsbury case be tried separately from the Granby cases. The defendant responded that he continued to believe that dismissal was the only appropriate remedy, and that, to avoid further delay in the proceedings, he wanted all of the cases to be tried together. The trial court granted the request to try the cases together.
After a trial, the jury returned a verdict of not guilty on all charges except risk of injury to a child in violation of § 53-21 (a) (1) in Docket No. H12M-CR-03-128673-S, and the trial court rendered judgments in accordance with the verdict. The defendant appealed to the Appellate Court from the judgment of conviction. He then filed a motion for articulation of the trial court’s reasons for denying his motion to dismiss, which the trial court granted. In its articulation, the court reiterated that, because none of the privileged documents was “in the form of a ‘communication’ from the defendant to counsel, but rather [contained] the narrative thoughts, musings and opinions of a layman,” on their face, they did not appear to be privileged. Nevertheless, because the [424]*424defendant had testified that he had communicated the documents to his attorney, the court concluded that the documents were covered by the attorney-client privilege. The court also reiterated that, because the privileged documents had not been given to the Granby police department, the defendant had not been prejudiced in the Granby cases and dismissal of the charges in those cases would have been inappropriate.
Thereafter, the trial court denied the defendant’s motion for further articulation. The Appellate Court then granted the defendant’s motion for review of the denial of his motion and ordered the trial court to render a further articulation on the following two questions: (1) “Whether, in denying the defendant’s motion to dismiss, the court considered his argument that the [prosecutor] received and reviewed the documents covered by the attorney-client privilege”; and (2) “What prejudice, if any, it found that the defendant suffered as a result of the [prosecutor’s] access to those documents.” In its further articulation, the trial court stated that “[t]he defendant failed to introduce sufficient credible evidence for the court to make factual findings as to the timing, nature and extent of the receipt, review and possible dissemination by the [prosecutor] of the documents covered by the attorney-client privilege.” The trial court further stated that it had denied the defendant’s motion to dismiss because he had not presented any evidence to support a showing of prejudice.
The defendant claims on appeal that the trial court improperly denied his motion to dismiss. Specifically, he claims that the trial court’s finding that the state had not intentionally invaded the attorney-client privilege when it read the materials taken from his computer was clearly erroneous and that the intentional invasion constituted a per se violation of the sixth amendment right to counsel for which dismissal is the sole appropriate remedy. In addition, the defendant claims that [425]*425he was irreparably prejudiced by the prosecutor’s invasion of the privileged material because it contained trial strategy.7 The state counters that, because the trial court properly found that the invasion of the privileged documents was unintentional, and because the defendant failed to establish that he was prejudiced by the disclosure, the trial court properly denied the motion to dismiss. The state further contends that, even if the defendant was prejudiced, the appropriate remedy would have been for the trial court to order a prosecutor who had not read the privileged documents to try the case, and the defendant had waived this remedy.
For the reasons that follow, we conclude generally that prejudice may be presumed when the prosecutor has invaded the attorney-client privilege by reading privileged materials containing trial strategy, regardless of whether the invasion of the attorney-client privilege was intentional. We further conclude that the state may rebut that presumption by clear and convincing evidence. Finally, we conclude that, when a prosecutor [426]*426has intruded into privileged communications containing a defendant’s trial strategy and the state has failed to rebut the presumption of prejudice, the court, sua sponte, must immediately provide appropriate relief to prevent prejudice to the defendant.
In the present case we conclude that, because the privileged materials at issue contained the defendant’s trial strategy and were disclosed to the prosecutor, the defendant was presumptively prejudiced by the prosecutor’s intrusion into the privileged documents. We further conclude that, because, after reviewing the privileged materials, the prosecutor tried the case to conclusion, the taint caused by the state’s intrusion into the privileged communications would be irremediable on retrial and the charge of which the defendant was convicted must be dismissed.
We begin our analysis with a review of the law governing governmental interference with the attorney-client privilege. “Connecticut has a long-standing, strong public policy of protecting attorney-client communications. . . . This privilege was designed, in large part, to encourage full disclosure by a client to his or her attorney so as to facilitate effective legal representation.” (Citation omitted; internal quotation marks omitted.) Gould, Larson, Bennet, Wells & McDonnell, P. C. v. Panico, 273 Conn. 316, 321-22, 869 A.2d 653 (2005); see also Hutchinson v. Farm Family Casualty Ins. Co., 273 Conn. 33, 38, 867 A.2d 1 (2005) (“the attorney-client privilege was created to encourage full and frank communication between attorneys and their clients and thereby promote broader public interests in the observation of law and administration of justice” [internal quotation marks omitted]).
Several courts have held that the government’s intrusion into privileged attorney-client communications constitutes an interference with the defendant’s right [427]*427to assistance of counsel in violation of the sixth amendment only when the intrusion has prejudiced the defendant. See United States v. Costanzo, 740 F.2d 251, 257 (3d Cir. 1984) (sixth amendment violation follows from finding of prejudice), cert. denied, 472 U.S. 1017, 105 S. Ct. 3477, 87 L. Ed. 2d 613 (1985); United States v. Steele, 727 F.2d 580, 585-86 (6th Cir.) (when government has intruded into attorney-client relationship, prejudice must be shown before constitutional violation can be found), cert. denied sub nom. Scarborough v. United States, 467 U.S. 1209, 104 S. Ct. 2396, 81 L. Ed. 2d 353 (1984); Briggs v. Goodwin, 698 F.2d 486, 495 (government intrusion into privileged information violates sixth amendment when “record suggests a realistic possibility that appellants suffered injury”), vacated on other grounds, 712 F.2d 1444 (D.C. Cir. 1983); see also Weatherford v. Bursey, 429 U.S. 545, 558, 97 S. Ct. 837, 51 L. Ed. 2d 30 (1977) (when government intrusion into privileged communications was not purposeful and did not result in tainted evidence or communication of defense strategy to prosecution, sixth amendment was not violated); cf. United States v. Morrison, 449 U.S. 361, 364, 367, 101 S. Ct. 665, 66 L. Ed. 2d 564 (assuming without deciding that government investigators violated sixth amendment when they met with defendant without knowledge or permission of her attorney, even without showing of prejudice, but concluding that remedy of dismissal was improper when assumed violation had no adverse impact on criminal proceedings), reh. denied, 450 U.S. 960, 101 S. Ct. 1420, 67 L. Ed. 2d 385 (1981).
A number of courts have held that, when the privileged communication contains details of the defendant’s trial strategy, the defendant is not required to prove he was prejudiced by the governmental intrusion, but prejudice may be presumed.8 In Briggs v. Goodwin, [428]*428supra, 698 F.2d 494-95, for example, the court stated that “[t]he prosecution makes a host of discretionary and judgmental decisions in preparing its case. It would be virtually impossible for an appellant or court to sort out how any particular piece of information in the possession of the prosecution was consciously or subconsciously factored into each of those decisions. Mere possession by the prosecution of otherwise confidential knowledge about the defense’s strategy or position is sufficient in itself to establish detriment to the criminal defendant. Such information is inherently detrimental . . . unfairly advantage [s] the prosecution, and threaten^] to subvert the adversary system of criminal justice. Further, once the investigatory arm of the government has obtained information, that information may reasonably be assumed to have been passed on to other governmental organs responsible for prosecution. Such a presumption merely reflects the normal high level of formal and informal cooperation which exists between the two arms of the executive.”9 (Internal quotation marks omitted.)
[429]*429Similarly, in United States v. Levy, 577 F.2d 200, 208 (3d Cir. 1978), the court held that, when the defendant’s trial strategy has been disclosed to the government, “there are overwhelming considerations militating against a standard which tests the sixth amendment violation by weighing how prejudicial to the defense the disclosure is.” In support of this conclusion, the court reasoned that “it is highly unlikely that a court can . . . arrive at a certain conclusion as to how the government’s knowledge of any part of the defense strategy might benefit the government in its further investigation of the case, in the subtle process of pretrial discussion with potential witnesses, in the selection of jurors, or in the dynamics of trial itself.”10 Id.
[430]*430Although the dissent disagrees with our reading of Levy, it has not cited a single case in which the government unintentionally obtained privileged information [431]*431relating to trial strategy, the prosecutor had knowledge of the privileged information, and the court held that, under Levy, prejudice could not be presumed because the intrusion was not intentional.11 Indeed, if, as the [433]*433dissent claims, the intent of the government is the dis-[434]*434positive issue in determining whether prejudice may be presumed when the government has intruded into privileged information relating to trial strategy, we are at a loss to understand why the court in Levy discussed the nature of the privileged information that had been intruded upon in that case at such length. See id., 209 (“The fundamental justification for the sixth amendment right to counsel is the presumed inability of a defendant to make informed choices about the preparation and conduct of his defense. Free two-way communication between client and attorney is essential if the professional assistance guaranteed by the sixth amendment is to be meaningful. The purpose of the attorney-client privilege is inextricably linked to the very integrity and accuracy of the fact finding process itself. Even guilty individuals are entitled to be advised of strategies for their defense. In order for the adversary system to function properly, any advice received as a result of a defendant’s disclosure to counsel must be insulated from the government. No severe definition of prejudice, such as the fruit-of-the-poisonous-tree evidentiary test in the fourth amendment area, could accommodate the broader sixth amendment policies. We think that the inquiry into prejudice must stop at the point where attorney-client confidences are actually disclosed to the government enforcement agencies responsible for investigating and prosecuting the case. Any other rule would disturb the balance implicit in the adversary system and thus would jeopardize the very process by which guilt and innocence are determined in our society. In the instant case confidential information was disclosed to the government authorities.”). If prejudice [435]*435may be presumed when the government has intentionally intruded into privileged information containing trial strategy because “advice received as a result of a defendant’s disclosure to counsel must be insulated from the government”; id.; and “it is highly unlikely that a court can . . . arrive at a certain conclusion as to how the government’s knowledge of any part of the defense strategy might benefit the government”; id., 208; prejudice may be presumed for the same reason when the intrusion was unintentional. Nowhere does the court in Levy suggest that the intent of the government somehow has a bearing on the prejudicial effect of such disclosures, and we cannot imagine how it might.12
Finally, a number of courts have held that the defendant is not required to prove that he was prejudiced by the government’s intrusion into attorney-client communications when the intrusion was deliberate and was unjustified by any legitimate governmental interest in effective law enforcement. See Shillinger v. Haworth, 70 F.3d 1132, 1141-42 (10th Cir. 1995); Morrow v. Superior Court, 30 Cal. App. 4th 1252, 1258, 36 Cal. Rptr. 2d 210 (1994) (when prosecutor intentionally orchestrated eavesdropping on conversation between defendant and attorney, burden fell on state to prove that punitive dismissal was not warranted because defendant had [436]*436not been prejudiced). The court in Shillinger reasoned that “no other standard can adequately deter this sort of misconduct.” Shillinger v. Haworth, supra, 1142.
We agree with the courts that have held that the burden is not on the defendant to establish that he was prejudiced when the prosecutor has intruded on attorney-client communications that contain information concerning the defendant’s trial strategy.13 Rather, [437]*437because the disclosure of such information is inherently prejudicial, prejudice should be presumed, regardless of whether the invasion into the attorney-client privilege was intentional. The subjective intent of the government and the identity of the party responsible for the disclosure simply have no bearing on that question.14
[438]*438We further conclude that the presumption of prejudice when trial strategy has been disclosed to the prosecutor may be rebuttable. For example, the state may be able to show that no person with knowledge of the privileged communications had any involvement in the investigation or prosecution of the case, the privileged communications contained only minimal information or that the state had access to all of the privileged information from other sources. In light of the important constitutional right at issue, however, we conclude that the state must rebut the presumption of prejudice by clear and convincing evidence. Cf. In re Jeisean M., 270 Conn. 382, 394, 852 A.2d 643 (2004) (“protected fundamental right of a parent to make child rearing decisions mandates that where a third party seeks visitation, that third party must allege and prove, by clear and convincing evidence, a relationship with the child that is similar in nature to a parent-child relationship, and that denial of the visitation would cause real and significant harm” [internal quotation marks omitted]); Miller v. Commissioner of Correction, 242 Conn. 745, 796, 700 A.2d 1108 (1997) (“[consistent with the heavy burden that [the clear and convincing] standard of proof imposes, courts and legislatures have employed it in constitutional . . . contexts involving extremely significant questions of fact”); State v. Jarzbek, 204 Conn. 683, 704-705, 529 A.2d 1245 (1987) (in light of defendant’s constitutional right to confrontation [439]*439of witnesses, state must prove compelling need to exclude defendant from witness room during videotaping of child’s testimony by clear and convincing evidence), cert. denied, 484 U.S. 1061, 108 S. Ct. 1017, 98 L. Ed. 2d 982 (1988); cf. Morrow v. Superior Court, supra, 30 Cal. App. 4th 1258 (when state has eavesdropped on privileged communications, burden falls on state to prove that sanctions are not warranted because there was no substantial threat of demonstrable prejudice).
In the present case, even a cursory review of the materials reveals that the defendant was presumptively prejudiced by the prosecutor’s intrusion into the privileged communications taken from the defendant’s computer because the privileged materials contained a highly specific and detailed trial strategy. Moreover, because the state’s case in Docket No. H12M-CR-03-128673-S was based entirely on the complainant’s account of the defendant’s conduct,15 and because the privileged communications contained highly specific facts relating to the credibility of the complainant and the adequacy of the police investigation in that case, the communications went to the heart of the defense.16 [440]*440Finally, the communications contained statements by the defendant of how best to defend the case, as opposed to general trial strategy being conveyed by an attorney to the client. Accordingly, we conclude that, contrary to the trial court’s finding, it may be presumed that the prosecutor’s intrusion into the communications was highly prejudicial.17
In light of this conclusion, we need not address the defendant’s claims that the trial court’s finding that the prosecutor’s intrusion into the privileged materials had not been intentional was clearly erroneous, and that a showing of prejudice is not required when the intrusion was intentional. We must state, however, that we are extremely troubled by the prosecutor’s conduct in this case. Although the privileged documents were not in the form of letters or e-mails, it could not have been more obvious on the face of a number of the documents that they were intended to be communications to the [441]*441defendant’s attorney.18 For example, one of the documents stated near the top of the first page that “[t]he [442]*442following material is confidential and I would ask that you review it. If this is a case you believe you would have success in defending, I would like to schedule [an] appointment to discuss it.” Another document was entitled “Strategy Issues” and stated in the first sentence: “I think that in the short term, especially for the court appearance on June 8, 2004, that our objective should be threefold . . . .” The first two sentences of another document provided: “We were asked by our original attorney ... to keep a log of any events that we thought might pertain to this case. This document is the result . . . .” Moreover, the prosecutor expressly had been put on notice that there were materials in the defendant’s computer that were subject to the attorney-client privilege and had been ordered not to read them. It is clear to us, therefore, that the prosecutor either knew or should have known immediately upon beginning to read these statements that the documents were privileged and that he should have stopped reading at once and notified the defendant and the court immediately that they were in his possession.
Having concluded that the defendant was prejudiced by the prosecutor’s intrusion into the privileged communications, we turn to the defendant’s claim that the trial court abused its discretion when it denied his motion to dismiss. The United States Supreme Court has held that “[c]ases involving [s]ixth [a]mendment deprivations are subject to the general rule that remedies should be tailored to the injury suffered from the constitutional violation and should not unnecessarily infringe [443]*443on competing interests.” United States v. Morrison, supra, 449 U.S. 364. “Our approach has . . . been to identity and then neutralize the taint by tailoring relief appropriate in the circumstances to assure the defendant the effective assistance of counsel and a fair trial. The premise of our prior cases is that the constitutional infringement identified has had or threatens some adverse effect upon the effectiveness of counsel’s representation or has produced some other prejudice to the defense. Absent such impact on the criminal proceeding, however, there is no basis for imposing a remedy in that proceeding, which can go forward with full recognition of the defendant’s right to counsel and to a fair trial.” Id., 366. “More particularly, absent demonstrable prejudice, or substantial threat thereof, dismissal of the indictment is plainly inappropriate, even though the violation may have been deliberate.” (Emphasis added.) Id.
Thus, when a defendant has been prejudiced by governmental intrusions into privileged communications, the remedy must be tailored to cure the prejudice. It follows that, although dismissal of criminal charges is a drastic remedy; State v. Bergin, 214 Conn. 657, 672, 574 A.2d 164 (1990); and although the decision to grant or deny a motion to dismiss a criminal charge “rests within the sound discretion of the trial court, and is one that we will not disturb on appeal absent a clear abuse of that discretion”; State v. Kelly, 256 Conn. 23, 77, 770 A.2d 908 (2001); the remedy of dismissal is required when there is no other way to cure substantial prejudice to the defendant.
Moreover, having concluded that, as a matter of law, the burden is on the state to rebut the presumption of prejudice by clear and convincing evidence, we similarly conclude that, if the state has not met its burden of showing the absence of prejudice, the burden is on the state to prove by clear and convincing evidence [444]*444that any prejudice to the defendant can be cured by a less drastic remedy than dismissal, such as the appointment of a new prosecutor who has not been exposed to the privileged materials. In addition, when the trial court learns that a government official has obtained knowledge of the defendant’s trial strategy, it is incumbent on the court, sua sponte, to require the state to prove by clear and convincing evidence that prejudice to the defendant could be prevented by the proposed remedy and, if the state meets its burden, to order that relief, even in the absence of a request by the defendant. Cf. State v. Gaines, 257 Conn. 695, 708, 778 A.2d 919 (2001) (when evidence of conflict of interest is sufficient to alert reasonable trial court that defendant’s sixth amendment right to effective assistance of counsel is in jeopardy, trial court has duty to inquire into conflict sua sponte).
In the present case, the trial court improperly found that the defendant had not been prejudiced by the prosecutor’s intrusion into the privileged communications. Accordingly, it placed no burden on either party to devise an appropriate remedy.19 Thus, if the trial court and the state had been on notice of the standards for addressing claims involving governmental intrusions into privileged communications that we adopt in this opinion, we would conclude that the trial court abused its discretion in denying the defendant’s motion to dismiss. Because we are applying this standard for the first time, however, we recognize that it ordinarily would be appropriate to remand the case to the trial court for a new hearing on the motion to dismiss under the proper standard.
Under the circumstances of the present case, however, we conclude that a remand is not appropriate. [445]*445Even if we were to assume that the state could have proved before trial that a less drastic remedy than dismissal would have been an adequate remedy,20 now that the case has been tried by the prosecutor who read the privileged communications, it clearly would be impossible to eliminate the potential for prejudice to the defendant with any other sanction. The prosecutor had had knowledge of the defendant’s trial strategy during the one and one-half years preceding trial and, therefore, could use the information in preparing for trial. Indeed, the record strongly suggests that the prosecutor may have revealed the defendant’s trial strategy to witnesses and investigators.21 In addition, consciously or uncon[446]*446sciously, the prosecutor’s knowledge of the defendant’s trial strategy may have affected his selection and examination of witnesses during trial, which is now a matter of public record. Again, the record strongly suggests that the prosecutor drew on his knowledge of the privileged communications when examining the accusing witness in Docket No. H12M-CR-03-128673-S to anticipate and thereby neutralize what otherwise might have been a devastating cross-examination of that witness.22 [447]*447Even if he did not draw on this knowledge, however, we agree with the court in Briggs v. Goodwin, supra, 698 F.2d 494-95, that “[m]ere possession by the prosecution of otherwise confidential knowledge about the defense’s strategy or position is sufficient in itself to establish detriment to the criminal defendant.” Moreover, the testimony of tainted witnesses at the first trial [448]*448could be admissible in a second trial as prior inconsistent statements. See State v. Winot, 294 Conn. 753, 778, 988 A.2d 188 (2010). Finally, as we have indicated, the information in the privileged communications went to the heart of the defense in that case. Accordingly, even if the case were to be retried by a prosecutor who has not read the privileged communications, it would be impossible for the courts or the defendant to have any confidence that a second trial with a new prosecutor would be untainted by the constitutional violation in the first trial, particularly because the new prosecutor would necessarily have access to the transcript of the original trial. See United States v. Levy, supra, 577 F.2d 208 (after case has been tried to completion, “a trial court applying an actual prejudice test would face the virtually impossible task of reexamining the entire proceeding to determine whether the disclosed information influenced the government’s investigation or presentation of its case or harmed the defense in any other way”); id., 210 (“As a result of the district court’s decision that no sixth amendment violation occurred, the same strike force group which originally handled the case was allowed to proceed with the trial. The disclosed information is now in the public domain. Any effort to cure the violation by some elaborate scheme, such as by bringing in new case agents and attorneys from distant places, would involve the court in the same sort of speculative enterprise which we have already rejected. Even if new case agents and attorneys were substituted, we would still have to speculate about the effects of the old case agents’ discussions with key government witnesses. More important, public confidence in the integrity of the attorney-client relationship would be ill-served by devices to isolate new government agents from information which is now in the public domain. At least in this case, where the trial has [449]*449already taken place, we conclude that dismissal of the indictment is the only appropriate remedy.”).23
Finally, we address the state’s claim that the appointment of a new prosecutor would have been an adequate remedy before trial and, because the defendant insisted that dismissal was the only remedy that would prevent prejudice to him, the defendant is now precluded from claiming that he was harmed by the court’s failure to impose that remedy. We disagree. The following undisputed facts and procedural history are relevant to our resolution of this claim. The defendant argued to the trial court in his memorandum in support of his motion to dismiss that the appointment of a new prosecutor would not prevent prejudice to him because the privileged communications contained his trial strategy and had been in the possession of the prosecutor for a lengthy period of time.24 He expressly disavowed any claim that the privileged communications contained anything of inculpatory, as opposed to strategic, value to the state. Accordingly, he argued, suppression of the [450]*450documents also would not be an appropriate remedy. The state argued in its opposing memorandum that the appointment of a new prosecutor was not necessary because the prosecutor had not wilfully intruded into the privileged communications. At the conclusion of the hearing on the motion to dismiss, the trial court found that the defendant had not been prejudiced, but offered to sever the Granby cases in the apparent belief that any potential prejudice to the defendant arose exclusively from the possibility that the communications contained inculpatory evidence in the Granby cases, or information that could lead to the discovery of inculpatory evidence, and that the Simsbury police department had shared the information in the privileged communications with the Granby police department. The defendant emphatically rejected this proposal, presumably in the belief that the remedy would do nothing to prevent the prejudice to him resulting from the prosecutor’s knowledge of his trial strategy in the Granby cases — an assessment with which we agree. Neither the state nor the trial court suggested at that time that the appointment of a new prosecutor would be an appropriate remedy.
We have concluded that, when the trial court becomes aware of a potential sixth amendment violation resulting from an intrusion into privileged communications, it is incumbent on the court, sua sponte, to devise a remedy adequate to cure any prejudice to the defendant. We also have concluded that it was apparent on the face of the privileged communications at issue in the present case that the defendant would be prejudiced by the prosecutor’s knowledge of their contents. Accordingly, we conclude that it was incumbent on the trial court to devise an adequate remedy for the sixth amendment violation, even in the absence of any request by the defendant. The fact that the defendant believed that no remedy short of dismissal would be [451]*451adequate and, accordingly, did not affirmatively seek a lesser remedy did not relieve the trial court of this obligation.25 In any event, as we have indicated, it is unlikely that the appointment of a new prosecutor would have been an adequate remedy even before trial. See footnote 20 of this opinion. We therefore conclude that the defendant’s failure to request that remedy from the trial court does not preclude him from seeking dismissal of the criminal charge of which he was convicted on appeal.
This is a case in which the prosecutor clearly invaded privileged communications that contained a detailed, explicit road map of the defendant’s trial strategy. Compounding the problem, the prosecutor not only failed to inform the defendant and the trial court of the invasion immediately, but also continued to handle the case, to meet repeatedly with witnesses and investigators and ultimately to try the case to conclusion more than one year after the invasion occurred. Under these circumstances, any remedy other than the dismissal of the criminal charge of which the defendant was convicted would constitute a miscarriage of justice. Accordingly, we conclude that the charge of risk of injury to a child in violation of § 53-21 (a) (1) in Docket No. H12M-CR-03-128673-S must be dismissed.26
[452]*452The judgment is reversed only with respect to the defendant’s conviction of risk of injury to a child and the case is remanded to the trial court with direction to grant the defendant’s motion to dismiss that charge and to render judgment thereon; the judgments are affirmed in all other respects.
In this opinion NORCOTT, EVELEIGH and VERTE-FEUILLE, Js., concurred.
