This case involves discovery of the findings and conclusions of a defense-retained psychiatrist who examined the defendant, where the defendant asserts an insanity defense but does not intend to call that psychiatrist as a witness. The trial court ordered disclosure. We affirm the trial court's discovery order, with one modification. '
We are asked to reconsider our holdings in State v. Bonds, 98 Wn.2d 1, 653 P.2d 1024 (1982), cert. denied, 464 U.S. 831 (1983), that, when the issue of insanity is raised by the defense, the attorney-client privilege does not extend to the testimony of a psychiatrist, and the defendant waives his Fifth Amendment right against self-incrimination. We adhere to those holdings. In addition, we conclude that, regardless of whether the defense intends to call a defense-retained psychiatrist as an expert witness, neither this state's criminal discovery rules nor the work product doctrine preclude the State's discovery of that psychiatrist's written reports, or his testimony relating thereto, which are based on the psychiatrist's examination of a defendant who intends to rely upon an insanity defense. We further hold that the State may call that psychiatrist as a witness. We reject defendant's right to counsel and due process claims.1
On July 31, 1989, Larry Sturholm and Debra Sweiger were stabbed to death. The King County prosecutor charged William J. Pawlyk with two counts of aggravated first degree murder, but did not file notice of intent to seek the death penalty. At defense counsel's request, defendant was interviewed by psychiatrists Dr. G. Christian Harris and Dr. Emanuel Tanay. Pursuant to RCW 10.77.030 and CrR 4.2(c), the defense gave notice that defendant would *461rely on an insanity defense, and indicated that Dr. Tanay would be called to testify in support of that defense. The defense states that it will not call Dr. Harris.
When the State was informed of the insanity defense, it contacted Dr. Harris as a prospective witness and learned that he had interviewed defendant. The State moved to discover Dr. Harris' written reports of his interview of defendant and to interview Dr. Harris concerning his findings and the basis for his conclusions. The State also moved to discover the results of "any and all psychological testing that may have been performed on the defendant by anyone” and for copies of all court orders appointing experts to examine defendant at public expense. Clerk's Papers, at 4. Further, the State moved for copies of reports by any other psychiatrist, psychologist, or expert in the field of forensic medicine who examined defendant either before or after Dr. Tanay examined him. The State served Dr. Harris with a subpoena to testify and a subpoena duces tecum for his reports. The State maintained that it wants Dr. Harris as its expert witness, perhaps its only expert witness. The defense moved to quash the subpoenas.
On January 24, 1990, the trial court granted the discovery requests set out above, but did not allow discovery as to "any written letters between defense counsel and Dr. Harris, and Dr. Harris shall not be interviewed concerning any communications between Dr. Harris and defense counsel." Clerk's Papers, at 66. The order directs that the "State shall have access to the discovery materials . . . [Dr. Harris] used in order to form the basis for his opinion." Clerk's Papers, at 66. The trial court ordered that "all information provided to the State pursuant to this order be utilized at trial only in the event that expert testimony of a psychiatrist is admitted before the jury in support of the insanity defense at trial." Clerk's Papers, at 66. The court denied the defense motion to quash the subpoenas of Dr. Harris.
The State's request for discovery as to Dr. Tanay's examination of defendant was granted and is not at issue.
*462Defendant's motion for interlocutory discretionary review of the discovery order was granted by the Court of Appeals, and the matter was transferred here by this court. Proceedings at the trial court are stayed pending this decision.
Defendant raises a number of issues concerning the trial court's order, involving the attorney-client privilege, the privilege against self-incrimination, the right to counsel, the criminal court discovery rules and RCW 10.77, the work product doctrine, and due process. Each is addressed below.
Attorney-Client Privilege
Defendant argues that the trial court's order violates the attorney-client privilege both as to the ordered disclosures, and as to the State's use of Dr. Harris as a witness. Defendant maintains that language to the contrary in State v. Bonds, 98 Wn.2d 1, 653 P.2d 1024 (1982), cert. denied, 464 U.S. 831 (1983), is dicta. The State contends that Bonds controls.
In Bonds, a psychiatrist was appointed to assist the defendant in a juvenile decline hearing and was called by the defense to testify at the decline hearing. The juvenile court declined jurisdiction. Defendant pleaded not guilty and not guilty by reason of insanity. Defendant moved in limine that the State not be allowed to use the psychiatrist as a rebuttal witness at trial. His motion was denied, and the doctor was called to testify for the State. On appeal, defendant claimed that the psychiatrist's testimony was protected under the attorney-client privilege, since the doctor had been part of the defense team at the juvenile proceedings. This court rejected this contention on the basis that the public interest in full disclosure outweighs the privilege. A majority of this court found persuasive the reasoning in Saltzburg, Privileges and Professionals: Lawyers and Psychiatrists, 66 Va. L. Rev. 597, 635-42 (1980), where the author
argues that the defense psychiatrist's examination of defendant is likely to be more accurate on the issue of insanity than that of the prosecution's. The defense psychiatrist will generally *463examine defendant earlier than the prosecution. The examination will thus be closer to the time of the offense, when defendant's recollections are clearer and there is less likelihood that defendant's mental condition has changed. Moreover, a defendant might benefit by undergoing several psychiatric examinations, examining reports of psychiatrists unfavorable to his insanity defense, and tailoring his responses in subsequent examinations more favorably to his defense. Defendant is also likely to be more cooperative with his own psychiatrist and give a more accurate impression of his mental condition. Saltzburg argues, and we agree, that for these reasons all available evidence of defendant's mental condition should be put before the jury.
Bonds, at 21. This argument is consistent with previous decisions founded on the principle that when a defendant pleads mental irresponsibility, every act of his life is admissible. Bonds, at 22; State v. Music, 79 Wn.2d 699, 711-12, 489 P.2d 159 (1971), vacated on other grounds, 408 U.S. 940 (1972); State v. Huson, 73 Wn.2d 660, 666-67, 440 P.2d 192 (1968), cert. denied, 393 U.S. 1096 (1969). The court held that "the attorney-client privilege should not extend to the testimony of a psychiatrist when the issue of insanity is raised by the defense." Bonds, at 22.
Defendant argues that our conclusion in Bonds is dicta, and that the attorney-client privilege set out in RCW 5.60-.060(2) should extend to communications between a defendant and a psychiatric expert retained by defense counsel for the purpose of assisting counsel in preparing for trial. He reasons that unlike a treating psychiatrist, a psychiatrist retained by counsel to assist in the preparation of the defense is an agent of counsel for purposes of the attorney-client privilege. Defendant contends that he has not waived the privilege by offering testimony which opens the door or by using otherwise privileged information as the basis of opinion testimony.
Defendant mistakenly characterizes our holding in Bonds as dicta. He reasons that the holding is limited to cases where defense waives the attorney-client privilege by presenting testimony of the psychiatrist because in Bonds the defense presented the psychiatrist's testimony at the *464decline hearing. Defendant fails to recognize that a majority of the court refused to limit its holding in that fashion, as demonstrated by the fact that a dissent in Bonds expressly argued for such a limited holding. See Bonds, at 29 (Utter, J., dissenting). Instead, the majority's reasoning and its holding demonstrate that the attorney-client privilege does not extend to the testimony of the psychiatrist regardless of whether the defendant first calls the psychiatrist to the stand or otherwise uses the psychiatrist's written reports or the findings and conclusions resulting from the psychiatrist's examination of defendant as to the insanity question.
We are aware that other courts have split on this question. Some courts hold that when a defendant asserts an insanity defense, the attorney-client privilege is waived or otherwise does not apply as to a nontestifying defense-retained examining psychiatrist. E.g., Haynes v. State, 103 Nev. 309, 739 P.2d 497 (1987); State v. Craney, 347 N.W.2d 668 (Iowa), cert. denied, 469 U.S. 884 (1984); People v. Edney, 39 N.Y.2d 620, 350 N.E.2d 400, 385 N.Y.S.2d 23 (1976);2 State v. Carter, 641 S.W.2d 54 (Mo. 1982), cert. denied, 461 U.S. 932 (1983). Others hold that the attorney-client privilege applies. E.g., United States v. Alvarez, 519 F.2d 1036 (3d Cir. 1975); Houston v. State, 602 P.2d 784 (Alaska 1979); People v. Lines, 13 Cal. 3d 500, 531 P.2d 793, 119 Cal. Rptr. 225 (1975); Miller v. District Court, 737 P.2d 834 (Colo. 1987); State v. Pratt, 284 Md. 516, 398 A.2d 421 (1979).
*465We considered the question carefully in Bonds, and we decline to overrule our holding there. We adhere to our holding that the attorney-client privilege does not extend to the testimony of a psychiatrist when a defendant raises insanity as a defense. Bonds, at 22; State v. Jones, 99 Wn.2d 735, 750, 664 P.2d 1216 (1983); State v. Hutchinson, 111 Wn.2d 872, 882, 766 P.2d 447 (1989); accord, State v. Brewton, 49 Wn. App. 589, 591, 744 P.2d 646 (1987).
Self-Incrimination
Defendant contends that the ordered disclosure and use by the State of Dr. Harris as an expert witness violates his right against self-incrimination.
In Bonds, at 20, we held that statements uttered in the context of a psychiatric examination are removed from the reach of the Fifth Amendment when the defendant raises an insanity defense. Accord, State v. Jones, 111 Wn.2d 239, 246, 759 P.2d 1183 (1988); State v. Jones, 99 Wn.2d 735, 749, 664 P.2d 1216 (1983). We derived this conclusion from language in Estelle v. Smith, 451 U.S. 454, 465, 68 L. Ed. 2d 359, 101 S. Ct. 1866 (1981). In Smith, a capital murder case, the Court held that defendant's Fifth Amendment right against self-incrimination was violated by the State's presentation, during the penalty phase of the trial, of testimony by a psychiatrist on the issue of future dangerousness. The psychiatrist was appointed by the trial court, on the court's own motion, to exainine defendant on the question of his competency. Defendant neither asserted an insanity defense nor offered psychiatric testimony at trial. Defendant was not given Miranda warnings nor was counsel informed of the possible use of the examination on the issue of future dangerousness (and may not even have been informed about the psychiatric examination).
The Court emphasized the "distinct circumstances" of the case, Smith, at 466, and recognized that in other circumstances the State might have an interest in introducing psychiatric testimony to rebut an insanity defense:
*466When a defendant asserts the insanity defense and introduces supporting psychiatric testimony, his silence may deprive the State of the only effective means it has of controverting his proof on an issue that he interjected into the case. Accordingly, several Courts of Appeals have held that, under such circumstances, a defendant can be required to submit to a sanity examination conducted by the prosecution's psychiatrist.
Smith, at 465. This was the language we relied upon in State v. Bonds, 98 Wn.2d 1, 653 P.2d 1024 (1982), cert. denied, 464 U.S. 831 (1983), when we held that the Fifth Amendment does not extend to a psychiatric examination of defendant upon assertion of an insanity defense.
Subsequent to our decision in Bonds, the United States Supreme Court expressly held that "if a defendant requests a psychiatric examination in order to prove a mental-status defense, he waives the right to raise a Fifth Amendment challenge to the prosecution's use of evidence obtained through that examination to rebut the defense." Powell v. Texas, _ U.S. __, 106 L. Ed. 2d 551, 556, 109 S. Ct. 3146 (1989); Buchanan v. Kentucky, 483 U.S. 402, 422-23, 97 L. Ed. 2d 336, 107 S. Ct. 2906, reh'g denied, 483 U.S. 1044, 97 L. Ed. 2d 807, 108 S. Ct. 19 (1987). See Granviel v. Lynaugh, 881 F.2d 185, 190 (5th Cir. 1989), cert. denied, 110 S. Ct. 2577 (1990).
Defendant's Fifth Amendment right against self-incrimination is not violated by the trial court's ordered disclosures or the State's use of Dr. Harris as an expert witness to rebut defendant's insanity defense.
Defendant also relies upon RCW 10.77.020(4) as affording protection against self-incrimination. RCW 10.77 governs procedures concerning the defense of insanity and the competence of the defendant to stand trial. CrR 4.2(c). RCW 10.77.020(4) provides that
[a]ny time the defendant is being examined by court appointed experts or professional persons pursuant to the provisions of this chapter . . . [he] may refuse to answer any question if he believes his answers may tend to incriminate him or form links leading to evidence of an incriminating nature.
By its terms, the statute does not apply to Dr. Harris' examination of defendant because Dr. Harris' examination *467was not an examination pursuant to RCW 10.77 by a court appointed expert or professional person.
The trial court also ordered disclosure of copies of all court orders appointing experts to examine defendant at public expense, and the results of all psychiatric and psychological testing of defendant by anyone, and for any reports of any other psychiatrists or psychologists or other forensic experts examining defendant. The record before us contains no clue as to whether any further examinations of defendant have occurred (other than Dr. Tanay's), and, if so, by whom and under what circumstances they were conducted.
Thus, we do not know whether the trial court's order might encompass an examination conducted under RCW 10.77.060(1) (the examination referenced in RCW 10.77-.020(4)), and therefore make no comment as to the applicability of RCW 10.77.020(4) to possible additional examinations. Any further discussion would be purely speculative. We do note, however, that our recent reference to RCW 10.77.020(4) in State v. Hutchinson, 111 Wn.2d 872, 884, 766 P.2d 447 (1989) should not be read as implying that the statutory privilege against self-incrimination applies to any and all psychiatric evaluations of a defendant regardless of the circumstances; any such reading plainly would not comport with the express terms of RCW 10.77.
We note that defendant's argument set out in his brief is, in any event, concerned solely with the ordered disclosures relating to Dr. Harris' examination. The statutory privilege of RCW 10.77.020(4) does not apply to that examination.
Right to Counsel
Defendant maintains that ordering disclosure of statements he made to a defense-retained psychiatric expert and disclosure of that expert's opinion as to sanity, where the expert is not endorsed as a defense witness, violates his *468right to counsel. Defendant reasons that counsel's paramount duty of loyalty to the client, including maintaining confidentiality, the effectiveness of counsel's assistance, and the government's obligation not to interfere with defendant's exercise of the right to counsel are all implicated by the ordered disclosures and the State's use as a witness of the defense-retained psychiatrist.
Initially we note that while defendant suggests that some courts hold that the right to counsel is not violated because it is waived by assertion of an insanity defense, most courts finding no violation do not do so on the basis of waiver. Further, the United States Supreme Court has indicated that a defendant does not automatically waive his right to counsel merely by asserting an insanity defense. Powell v. Texas, 106 L. Ed. 2d at 556-57; accord, Granviel v. Lynaugh, supra.
Quite aside from any waiver question, however, we conclude that defendant's right to counsel is not violated by the trial court's ordered disclosures. In Buchanan v. Kentucky, supra, the defense joined in a request for a psychiatric examination for purposes of enabling petitioner (defendant) to receive psychiatric treatment while awaiting trial, and petitioner asserted a mental status defense— extreme emotional disturbance. The prosecution used a report prepared as a result of the requested examination to rebut petitioner's mental status defense. The Court rejected petitioner's right to counsel claim, first distinguishing the case from Estelle v. Smith, supra, by noting that petitioner had the opportunity to discuss the examination and its scope with counsel, unlike the situation in Smith. The petitioner in Buchanan argued, however, that although he agreed to the examination, he had no idea, because counsel could not anticipate, that results of the examination he requested might be used to undermine his mental status defense. The Court responded to this argument:
Petitioner, however, misconceives the nature of the Sixth Amendment right at issue here by focusing on the use of . . . *469[the] report rather than on the proper concern of this Amendment, the consultation with counsel, which petitioner undoubtedly had. Such consultation, to be effective, must be based on counsel's being informed about the scope and nature of the proceeding. There is no question that petitioner's counsel had this information. To be sure, the effectiveness of the consultation also would depend on counsel's awareness of the possible uses to which petitioner's statements in the proceeding could be put. Given our decision in Smith, however, counsel was certainly on notice that if, as appears to be the case, he intended to put on a "mental status" defense for petitioner, he would have to anticipate the use of psychological evidence by the prosecution in rebuttal. In these circumstances, then, there was no Sixth Amendment violation.
(Footnote omitted.) Buchanan, at 424-25.
The Court's reasoning applies here. Counsel clearly knew about the nature and scope of the proceeding, and was on notice not only as a result of Estelle v. Smith, 451 U.S. 454, 68 L. Ed. 2d 359, 101 S. Ct. 1866 (1981), but also as a result of Bonds, of the possible use of the psychological evidence by the prosecution in rebuttal. Despite defendant's wish to have us rewrite Bonds we decline to do so, and, because we there held that neither the Fifth Amendment nor the attorney-client privilege offered protection from psychiatric testimony upon defendant's assertion of an insanity defense, defense counsel was on notice that evidence resulting from Dr. Harris' examination might be used by the prosecution to rebut defendant's insanity defense. Further, the examination here was clearly intended to concern a possible insanity defense and, needless to say, defense counsel was aware of this.
We are not persuaded by defendant's specific arguments relating to counsel's obligation to maintain confidentiality, counsel's effectiveness, and defendant's right to be free of improper governmental interference with his right to counsel. First, we perceive defendant's arguments in part as a recasting of defendant's attorney-client privilege claim as a constitutional right to counsel claim. We do not agree that the attorney-client privilege is of constitutional dimension. See United States ex rel. Edney v. Smith, 425 F. Supp. 1038, 1054 (E.D.N.Y. 1976) (court declined to *470freeze attorney-client-psychiatrist privilege into constitutional form), aff'd, 556 F.2d 556 (2d Cir.), cert. denied, 431 U.S. 955 (1977).
Moreover, in addition to the reasoning of the United States Supreme Court in Buchanan v. Kentucky, 483 U.S. 402, 97 L. Ed. 2d 336, 107 S. Ct. 2906, reh'g denied, 483 U.S. 1044, 97 L. Ed. 2d 807, 108 S. Ct. 19 (1987), we are inclined to agree with the court in State v. Craney, 347 N.W.2d 668, 677 (Iowa), cert. denied, 469 U.S. 884 (1984), that defendant's asserted right to the effective assistance of counsel under the facts of this case reflects the "bygone philosophy that for an attorney's investigations to be effective they must be shrouded in secrecy." If defendant asserts an insanity defense, evidence pertaining to that defense must be available to both sides at trial. There is thus no need for the confidentiality defendant maintains is required.
We find no violation of defendant's right to counsel resulting from the trial court's ordered disclosures or the State's use of Dr. Harris as a witness. Other courts have reached the same conclusion under similar circumstances. See, e.g., United States ex rel. Edney v. Smith, 425 F. Supp. 1038, 1053-54 (E.D.N.Y. 1976), aff'[d, 556 F.2d 556 (2d Cir.), cert. denied, 431 U.S. 958 (1977); Lange v. Young, 869 F.2d 1008 (7th Cir.), cert. denied, 490 U.S. 1094 (1989); Noggle v. Marshall, 706 F.2d 1408 (6th Cir.), cert. denied, 464 U.S. 1010 (1983); State v. Craney, 347 N.W.2d 668 (Iowa), cert. denied, 469 U.S. 884 (1984); State v. Dodis, 314 N.W.2d 233 (Minn. 1982).
Discovery Rules; RCW 10.77
Defendant argues that the trial court's authority to order discovery where the defendant intends to assert an insanity defense is governed exclusively by CrR 4.7 and RCW 10.77. Defendant contends that the discovery order here is not authorized under either the court rule or the statute.
The scope of discovery is within the sound discretion of the trial court and its decisions will not be disturbed *471absent manifest abuse of that discretion. State v. Yates, 111 Wn.2d 793, 797, 765 P.2d 291 (1988); State v. Boehme, 71 Wn.2d 621, 633, 430 P.2d 527 (1967), cert. denied, 390 U.S. 1013 (1968). CrR 4.7 governs criminal discovery. State v. Hutchinson, 111 Wn.2d 872, 876, 766 P.2d 447 (1989). The rule guides the trial court in the exercise of its discretion over criminal discovery. Yates, at 797. CrR 4.7 is a reciprocal discovery rule which contains the prosecutor's and defendant's obligations in engaging in discovery. Yates, at 797; Hutchinson, at 878-79. The rule also allows for additional and discretionary disclosures and delineates matters not subject to disclosure. Yates, at 797.
As this court has stated, and repeated, sound policy underscores the reciprocal nature of the discovery rules:
[W]e . . . observe that the rules of discovery are designed to enhance the search for truth in both civil and criminad litigation. And, except where the exchange of information is not otherwise clearly impeded by constitutional limitations or statutory inhibitions, the route of discovery should ordinarily be considered somewhat in the nature of a 2-way street, with the trial court regulating traffic over the rough areas in a manner which will insure a fair trial to all concerned, neither according to one party an unfair advantage nor placing the other at a disadvantage.
Boehme, at 632-33; Yates, at 799.
This policy must be kept in mind when examining the scope of CrR 4.7, as well as the principle of liberalized discovery to serve the purposes underlying CrR 4.7 "to provide adequate information for informed pleas, expedite trials, minimize surprise, afford opportunity for effective cross-examination, and meet the requirements of due process" while keeping discovery "consistent with protections of persons, effective law enforcement, the adversary system, and national security." Yates, at 797 (quoting Criminal Rules Task Force, Washington Proposed Rules of Criminal Procedure 77 (West Pub'g Co. ed. 1971) (quoting ABA Standards Relating to Discovery and Procedure Before Trial, Std. 1.2, at 34 (Approved Draft, 1970))). CrR 1.2 directs that the Superior Court Criminal Rules are to be *472"construed to secure simplicity in procedure, fairness in administration, effective justice, and the elimination of unjustifiable expense and delay."
We address, in turn, the possible application of CrR 4.7-(b)(1), (g), and (b)(2)(x).
CrR 4.7(b)(1) provides that a defendant is obliged to disclose "the names and addresses of persons whom the defendant intends to call as witnesses at the hearing or trial, together with any written or recorded statements and the substance of any oral statements of such witness." Because the defense does not intend to call Dr. Harris, we agree with defendant that this provision does not authorize discovery of Dr. Harris' records or observations.
CrR 4.7(g) states:
Subject to constitutional limitations, the court may require the defendant to disclose any reports or results, or testimony relative thereto, of physical or mental examinations or of scientific tests, experiments or comparisons, or any other reports or statements of experts which the defendant intends to use at a hearing or trial.
This provision applies to reports and results of mental examinations, and other reports and statements of experts, including medical and scientific reports and results. However, this provision provides for disclosure of those reports, results, or statements which will be used at trial. Defendant states that Dr. Harris will not testify at trial and that his evaluation and reports will not form the basis for other expert testimony at trial. Under these circumstances, CrR 4.7(g) does not authorize the disclosure ordered by the trial court.
CrR 4.7 (b) (2) (x) authorizes the trial court to require the defendant to "allow inspection of physical or documentary evidence in defendant's possession." In Yates, this provision was held to give the trial court discretionary authority to order that recorded or written statements of potential prosecution witnesses which were taken by defense counsel or the defense investigator be provided to the State. Defendant argues that the holding in Yates is limited to statements of persons who will be testifying at trial, and *473that Yates teaches that this discretionary portion of the discovery rule does not contemplate a defense obligation to disclose all documents in its files, because if that were the rule, this court in Yates would also have upheld ordered disclosure of defense interview notes.
Contrary to defendant's arguments, we did not restrict production of documentary evidence under CrR 4.7(b) (2) (x) to that pertaining to witnesses who will be called to testify at trial. Under the facts in Yates, the recorded statements were of witnesses who were to be called at trial, and we simply recounted this fact in the context of our holding. Moreover, we agree that not all defense documentary material is discoverable under this section. Such information may be protected under the work product doctrine, the attorney-client privilege, or defendant's right not to incriminate himself, for example. However, the fact that CrR 4.7 (b) (2) (x) does not authorize discovery of all documents in defendant's file does not resolve the question whether a particular document may be discovered under the section.
We conclude that where the defendant asserts an insanity defense, CrR 4.7(b)(2)(x) authorizes the court, in its discretion, to order disclosure of written reports in the possession of the defendant or defense counsel which have been prepared by defense psychiatrists who examine defendant on the issue of sanity. Such reports are documentary evidence within the scope of CrR 4.7(b)(2)(x). As to testimony relating thereto, we perceive no bar in CrR 4.7 or RCW 10.773 to discovery from the psychiatrist of his findings and the basis for his conclusions.
In concluding that CrR 4.7(b)(2)(x) authorizes the ordered discovery, we are aware of defendant's various arguments relating to principles of statutory construction *474which we apply in construing court rules. See State v. Hutchinson, at 877 (citing State v. Baxter, 45 Wn. App. 533, 540, 726 P.2d 1247 (1986), overruled on other grounds in State v. Hanson, 52 Wn. App. 368, 760 P.2d 941, review denied, 111 Wn.2d 1030 (1988)). In key part, defendant argues that because CrR 4.7(g) specifically relates to scientific and medical evidence, it controls discovery of such material. Because CrR 4.7(g) grants discretionary authority to compel disclosure when the materials will be used by defendant at trial, defendant reasons, the ordered discovery is not authorized where defendant does not use the materials at trial.
We do not read CrR 4.7(b) (2) (x) and (g) so narrowly. If materials will be used at trial, CrR 4.7(g) grants the court discretionary authority to order disclosure. Documentary evidence in defendant's possession which defendant does not intend to use at trial is within the scope of CrR 4.7(b) (2) (x), and the trial court has authority to order disclosure in the exercise of its sound discretion. Discovery under both provisions is subject to constitutional limitations.
Moreover, if we accepted defendant's parsing of the rule we would have to place form over substance. The principles and policies of criminal discovery would be ill served by ignoring the compelling reasons for permitting discovery of a defense-retained psychiatrist's report on defendant's sanity, solely on the ground that under one possible construction of the criminal court discovery rule the rule does not expressly authorize discovery.
Our conclusion that the rule allows the ordered discovery is consistent with the general principles relating to criminal discovery which we have recounted above. More particularly, it would be manifestly unjust to permit defendant to assert an insanity defense, place his mental state directly in issue, and then allow him protection from discovery of what may be the best evidence, and perhaps the only truly accurate evidence, relating to his mental state. Also, as the court in Lange v. Young, 869 F.2d 1008, 1013 (7th Cir.), cert. *475denied, 490 U.S. 1094 (1989) observed, unlike other issues in a criminal trial, the insanity defense is distinctive because the defendant is the sole source of evidence on his sanity and therefore has the opportunity to manipulate the information which the State receives. Allowing the State access to a defense-retained psychiatrist's reports, findings, and conclusions serves to equalize the relative positions of the parties on this issue, and avoids according the defendant an unfair advantage. Thus, discovery here serves the policy and purposes underscoring the criminal discovery rule.
Moreover, there is no question but that if a State selected psychiatrist examined defendant and found him insane, the defendant would be entitled to this information as a matter of due process. See Brady v. Maryland, 373 U.S. 83, 10 L. Ed. 2d 215, 83 S. Ct. 1194 (1963). Given the reciprocal nature of the criminal discovery process and the unique nature of the evidence at issue, the State should be entitled in the discretion of the trial court to discovery of a defense-retained psychiatrist's reports and the findings and the basis for his conclusions.
Work Product
Defendant claims that absent a showing of exceptional circumstances, the findings and conclusions of defense consulting experts are protected by the work product doctrine.
Our discussion of this issue which follows is limited to the context in which the issue arises in this case. Our analysis is to have no effect in civil cases, where different policies, interests and circumstances may dictate a different analysis or result.
The work product doctrine protects from discovery an attorney's work product, so that attorneys can "work with a certain degree of privacy and plan strategy without undue interference." Coburn v. Seda, 101 Wn.2d 270, 274, 677 P.2d 173 (1984) (citing Hickman v. Taylor, 329 U.S. 495, 510-11, 91 L. Ed. 2d 451, 67 S. Ct. 385 (1947)). The *476immunity is not absolute; whether the work product doctrine will afford protection depends on both the type of material sought to be discovered and the adversary's need for it. E. Epstein & M. Martin, The Attorney-Client Privilege and the Work-Product Doctrine 99 (2d ed. 1989).
The work product doctrine is most often asserted in civil litigation, but the doctrine applies as well in criminal proceedings. United States v. Nobles, 422 U.S. 225, 238, 45 L. Ed. 2d 141, 95 S. Ct. 2160 (1975).
At its core, the work-product doctrine shelters the mental processes of the attorney, providing a privileged area within which he can analyze and prepare his client's case. But the doctrine is an intensely practical one, grounded in the realities of litigation in our adversary system. One of those realities is that attorneys often must rely on the assistance of investigators and other agents in the compilation of materials in preparation for trial. It is therefore necessary that the doctrine protect material prepared by agents for the attorney as well as those prepared by the attorney himself.
(Footnote omitted.) Nobles, at 238-39. See also Heidebrink v. Moriwaki, 104 Wn.2d 392, 396, 706 P.2d 212 (1985).
Defendant argues that Dr. Harris is an agent of defense counsel whose work is therefore protected by the work product doctrine. Defendant then reasons that under CR 26(b)(4)(B) the State must demonstrate exceptional circumstances before disclosure of the psychiatrist's work product may be had. Amici on behalf of Washington Association of Criminal Defense Lawyers and Washington State Trial Lawyers Association also urge us to follow the rule in CR 26(b)(4)(B).
As we have previously said, "the civil rules by their very terms apply only to civil cases." State v. Gonzalez, 110 Wn.2d 738, 744, 757 P.2d 925 (1988) (citing CR 1; State v. Christensen, 40 Wn.2d 329, 242 P.2d 755 (1952) (CR 26 does not apply in criminal cases)). In Gonzalez, at 744, we reasoned that "CrR 4.7 sets out the exact obligations of the prosecutor and defendant in engaging in discovery, the detail of which suggests to us that no further supplementation should be sought from the civil rules.''
*477We decline to apply CR 26 in this criminal case.4 CrR 4.7 specifically addresses the work product doctrine.
Pursuant to CrR 4.7(f)(1):
Disclosure shall not be required of legal research or of records, correspondence, reports or memoranda to the extent that they contain the opinions, theories or conclusions of investigating or prosecuting agencies except as to material discoverable under subsection (a)(1) (iv).
This section is a codification of the attorney's work product privilege in the criminal context, and applies to both the prosecution and the defense. 12 R. Ferguson, Wash. Prac., Criminal Practice and Procedure § 1304, at 250 (1984). While the section specifically addresses the prosecution's work product and does not mention the word "defense" or "defendant," we conclude that the rule necessarily applies to defense work product as well as to prosecution work product. The language of the rule lends itself to this construction, as the reference to "investigating . . . agencies" is broad enough to include defense work product.
The work product protection described in CrR 4.7(f)(1) does not extend to certain reports and testimony *478of experts: The exception noted in the rule, CrR 4.7(a)(1)(iv), directs disclosure by the prosecution of "any reports or statements of experts made in connection with the particular case, including results of physical or mental examinations and scientific tests, experiments, or comparisons." CrR 4.7(g) similarly allows discovery of such information from the defense, although, as noted above, this section pertains to such materials to be relied upon by defendant at trial. The point to be made is, however, that CrR 4.7 plainly contemplates that such information is not protected by the work product doctrine. Accord, 12 R. Ferguson, Wash. Prac., Criminal Practice and Procedure § 1304, at 250 (1984).
The reason CrR 4.7 does not provide protection for such information which the defense obtains is that " [disclosure by the accused is required in an area where the prosecution has a particular need to have time for extensive preparation, and where the defense material is least likely to present conflicts with privileges accorded to the accused." Criminal Rules Task Force, Washington Proposed Rules of Criminal Procedure 83 (West Pub'g Co. ed. 1971). This same reasoning applies whether the defense intends to call its examining psychiatrist or not. Once the defendant puts the question of insanity at issue, the State has exceptional need for evidence to rebut the insanity defense. As explained in this opinion, none of the constitutional principles invoked by defendant preclude the ordered disclosures, nor does the attorney-client privilege. Thus, the information at issue is as described in the Criminal Rules Task Force report: the State has an overwhelming need for the information, and the relevant privileges generally accorded an accused do not provide protection from disclosure. Under these circumstances, neither should the work product doctrine (if otherwise implicated) provide protection from disclosure of a psychiatrist's report on defendant's insanity and the psychiatrist's testimony relating to *479his findings and the basis for his conclusions. See Tomlinson, Constitutional Limitations on Prosecutorial Discovery, 23 San Diego L. Rev. 993, 1050 (1986).5
We recognize, nonetheless, that the work product doctrine does apply to some extent in this case. While it does not preclude disclosure of the psychiatrist's factual findings and opinions on the issue of defendant's insanity, it does operate to preclude disclosure of defense counsel's "opinions, theories or conclusions." See State v. Yates, 111 Wn.2d 793, 801, 765 P.2d 291 (1988). The trial court excluded from disclosure any letters or communications between Dr. Harris and defense counsel. It appears that this exclusion was intended to protect this type of information from disclosure, and we agree that this limitation is appropriate. See People v. Edney, 39 N.Y.2d 620, 350 N.E.2d 400, 403, 385 N.Y.S.2d 23 (1976). While it seems doubtful that Dr. Harris' psychiatric reports would contain any such information, if defendant believes they do he may request the trial court to examine the materials in camera and to protect any such work product from disclosure.
*480Due Process
Defendant maintains that his constitutional rights to due process and fundamental fairness would be violated if the State were allowed to use against him statements made to a defense consulting psychiatrist in justifiable reliance on the attorney-client privilege and his right to counsel. In that we have rejected defendant's claims that the statements are protected by either the attorney-client privilege or the right to counsel, it follows that we also reject defendant's due process claim.
In conclusion, we uphold the order compelling discovery and permitting the State to call Dr. Harris as a witness. The defendant may, however, request in camera examination of Dr. Harris' reports if he believes they describe the type of work product which we have explained should be protected, and the trial court should protect such work product from discovery should it be found in the reports. We emphasize that, as the trial court further ordered, the information provided to the State pursuant to the order is to be utilized at trial only if expert testimony of a psychiatrist in support of an insanity defense is presented before the jury, for the purpose of rebutting the insanity defense.
Callow, C.J., and Dolliver, Dore, Andersen, and Durham, JJ., concur.
We note that although defendant relies upon relevant provisions of the Washington State Constitution, he does not argue that any different analysis applies as to any issue than applies under the federal constitution.
On defendant's petition for a writ of habeas corpus in Edney, the United States District Court for the Eastern District of New York addressed his argument that the State should not be able to call a defense-retained psychiatrist who examined defendant on the issue of a mental status defense. The court commented that
defendant suggests that he be permitted to suppress any unfavorable psychiatric witness whom he had retained in the first instance, under the guise of attorney-client privilege, while he endeavors to shop around for a "friendly" expert, and take unfriendly experts off the market.
United States ex rel. Edney v. Smith, 425 F. Supp. 1038, 1052 (E.D.N.Y. 1976), aff'd, 556 F.2d 556 (2d Cir.), cert. denied, 431 U.S. 958 (1977).
We note that RCW 10.77.100 provides:
"Subject to the rules of evidence, experts or professional persons who have reported pursuant to this chapter may be called as witnesses at any proceeding held pursuant to this chapter. Both the prosecution and the defendant may summon any other qualified expert or professional persons to testify." (Italics ours.)
In relevant part, CR 26(b)(4)(B), which applies to facts and opinions acquired or developed in anticipation of litigation, provides that a party may obtain facts known or opinions held by an expert who is not expected to be called as a witness only "upon a showing of exceptional circumstances under which it is impracticable for the party seeking discovery to obtain facts or opinions on the same subject by other means."
Even if we agreed with defendant that this rule applies we would have no trouble upholding the trial court's ordered disclosures. While it is true that the State may have defendant examined by its own psychiatrist, RCW 10.77.060, such an examination cannot be deemed an adequate substitute for evidence of a defense examination. Defense examinations generally occur closer to the time of the alleged crime, and before the defendant's condition changes or he "tailors” responses, and the defendant is more likely to give an accurate impression of his mental condition to his own psychiatrist. See State v. Bonds, 98 Wn.2d 1, 21, 653 P.2d 1024 (1982) (citing Saltzburg, Privileges and Professionals: Lawyers and Psychiatrists, 66 Va. L. Rev. 597, 635-42 (1980)), cert. denied, 464 U.S. 831 (1983). Thus, even if CR 26(b)(4)(B) were applied, the State could readily meet its burden of establishing "exceptional circumstances"—it is not merely impracticable for the State to obtain the facts and opinions on defendant's sanity or insanity which the defense obtains through such an examination, it is virtually impossible.
In reaching this conclusion we note that there appears to be a question whether facts and opinions obtained by a defense-retained expert actually constitutes "work product." The language in CrR 4.7(f)(1) referring to "legal research" and "opinions, theories or conclusions" arguably does not encompass the objective observations and reports of a retained psychiatrist. See, e.g., Morris v. State, 59 Md. App. 659, 669, 477 A.2d 1206 (1984) (work product doctrine intended to protect and act as limitation on pretrial discovery of attorney's strategies, legal theories, and mental impressions, and was never intended as an evidentiary privilege, as evidenced by Maryland rule granting the State pretrial discovery of written reports of defense experts who will be called as witnesses at trial).
The parties have not addressed the question under CrR 4.7.
In the civil context, facts known and opinions held by a party's expert who is not expected to be called at trial as a witness are sometimes referred to as work product. However, CR 26(b)(4) is modeled after Fed. R. Civ. P. 26(b)(4), and the comments to the federal rule disclose that the rule rejects as
ill-considered the decisions which have sought to bring expert information within the work-product doctrine. . . . The provision adopts a form of the more recently developed doctrine of "unfairness."
