OPINION

CROSKEY, J. —

The petitioners, Fireman's Fund Insurance Company and National Surety Corporation (hereinafter, collectively Fireman's Fund), seek a writ of mandate vacating the trial court's order of November 18, 2010, which required an attorney, who was a member of a law firm that had formerly represented Fireman's Fund in this litigation, to answer at her deposition five questions to which objections of attorney-client privilege and/or work product privilege had been asserted. In overruling these objections, the trial court generally held that (1) the attorney-client privilege applies only to communications directly between an attorney and his or her client, but does not extend to communications among and between multiple counsel (or other reasonably necessary parties) who are representing the client and (2) the absolute work product privilege applies only to an attorney's work product that has been reduced to written form.

As we explain, the trial court's ruling improperly restricted the scope of these two privileges. We will therefore grant the petition and remand with directions.

FACTUAL AND PROCEDURAL BACKGROUND

Front Gate Plaza, LLC (hereinafter Front Gate), owns and operates a shopping mall in Lancaster, California. Primero Management, Inc. (Primero), provides management and accounting services for Front Gate. Raymond Arjmand, either individually or as trustee for the Arjmand Family Trust (Arjmand), is a managing member of Front Gate and the principal of Primero. Primero apparently provides management and accounting services not just for Front Gate, but for other Arjmand-owned entities as well.

In April of 2008,1 Front Gate filed this action against Fireman's Fund alleging, among other things, bad faith in the handling of certain property damage claims that had allegedly been sustained by Front Gate on July 20, 2006, as the result of wind- and rainstorms. Front Gate claimed that Fireman's Fund had conducted an improper investigation and evaluation of the claims and, as a result, monetary benefits due under Fireman's Fund's policy were unreasonably delayed or denied.

In May of 2009, Fireman's Fund's counsel, Carlson, Calladine & Peterson LLP (CCP), was contacted by Sunil Chand (Chand), the acting director of accounting for Primero, who claimed to be a whistleblower in possession of evidence demonstrating that Front Gate's insurance claims were fraudulent. Chand spoke with Attorney Melissa Dubbs, an associate at CCP. Chand initially made several calls to Dubbs without disclosing his name. Dubbs referred Chand to Pamela Pierce (Pierce), an investigator retained by CCP, who traced Chand's calls and discovered his identity.

According to Chand, he had discovered, while working at Primero, that his employer was engaging in financial and accounting irregularities with respect to Front Gate and another Arjmand entity, not a party to these proceedings. According to Chand, Front Gate sought insurance compensation for expenses which did not arise from covered events, submitted inflated repair bids from vendors who were part of Arjmand's scheme, and split insurance proceeds with the vendors who had submitted the inflated bids. Chand was fired by Arjmand on June 2, 2009, shortly after he informed Arjmand that he had filed amended 1099 forms for certain vendors and asserted that he no longer wished to be a party to Arjmand's fraud.2 According to Front Gate, Chand was a vindictive former employee who had lied on his resume, saw conspiracies where none existed, and had a history of making baseless accusations against prior employers.

On or about June 7, 2009, Chand met with Dubbs and investigator Pierce in CCP's office in San Francisco. He brought with him and delivered documents that he had copied from Primero's records. At the request of Dubbs, CCP partner Donald Carlson wrote a check to Chand for $1,000 to reimburse him for his time and travel expense in coming from Los Angeles to San Francisco.3

In August 2009, CCP attorney Robert Peterson advised Front Gate's counsel that CCP had received 5,450 pages of documents "which, in our opinion, constitute evidence of a criminal conspiracy and crimes on the part of your clients." Peterson demanded that Front Gate produce the documents described by Chand because they were responsive to Fireman's Fund's discovery requests.

In September 2009, Fireman's Fund filed a cross-complaint against Front Gate, Primero, Arjmand and others,4 alleging that Front Gate had submitted fraudulent claims to Fireman's Fund and had conspired with others to commit insurance fraud. Fireman's Fund's motion for leave to file the cross-complaint was supported, in part, by a declaration from Chand, which had been drafted by Attorney Peterson.

The parties became embroiled in protracted discovery disputes over the so-called "Chand documents/incident" because real parties in interest refused to produce copies of the documents that Chand had provided to CCP and sought to preclude Fireman's Fund from using these documents in this litigation. On November 6, 2009, at Fireman's Fund's request, the trial court designated retired Los Angeles Superior Court Judge Arnold Gold (hereinafter, the Referee) to assist the court with "issues raised by the Chand documents incident." Specifically, the court authorized the Referee to "hear, determine and make recommendations" as to: "(1) All discovery and evidentiary issues and the use of the Chand documents in the litigation, (2) whether defendants had violated their ethical and legal duties, and (3) whether plaintiffs or any other party or attorney had violated their legal or ethical duties by suppressing or withholding documents or evidence in previous responses to defendant's discovery request."

The dispute at issue in this writ proceeding surrounds certain questions propounded at the deposition of Attorney Dubbs.5 We note that, at the first session of her deposition, in response to Fireman's Fund's assertion of the attorney-client and work product privileges,6 it was argued that the crime-fraud exception applied, based on Chand's alleged theft of the documents. A hearing was held, and the Referee determined that the crime-fraud exception did not apply. That ruling is not at issue in this proceeding.

Thereafter, real parties in interest requested, in September of 2010, that the Referee compel Attorney Dubbs to answer 10 specific questions to which Fireman's Fund had previously objected on privilege grounds. On October 3, 2010, the Referee issued his fourth report and recommendation (Fourth Report) recommending that Dubbs be compelled to answer all 10 questions. Fireman's Fund then agreed to let her answer five of those questions. (Questions 1, 2, 3, 4 and 8.) With respect to the remaining five questions (questions 5, 6, 7, 9 and 10), however, Fireman's Fund argued that the attorney client and/or the absolute work product privileges (Code Civ. Proc., § 2018.030, subd. (a))7 applied and she could not be compelled to answer them. Over Fireman's Fund's objections, the trial court approved the Referee's recommendation and, on November 18, 2010, ordered that Dubbs answer the following five questions (and "reasonable follow-up questions seeking non-privileged information"):

(5) Q: "Do you know how Mr. Peterson drafted the declaration of Mr. Chand without meeting with Mr. Chand?"8

A: "I think I know."

Q: "And what is it?"9

(6) Q: "What did you tell Mr. Carlson in order for him to write a personal check to Mr. Chand?"

(7) Q: "Was Pamela Pierce aware that Sunil Chand was paid $1,000 on your initial meeting with Mr. Chand?"

A: "Yes. . . . She was aware of it because she and I had a discussion about how to—how to pay Mr. Chand—how to pay Mr. Chand $1,000."

Q: "What were those discussions?"

(9) Q: "Did you prepare any subpoenas based on any documents that Chand gave you[?]"

A: "Yes."

Q: "Which ones?"

(10) "Did you explain who Mr. Chand was to Mr. Carlson before he wrote the check?"

The Referee (and the trial court) took a very narrow and restricted view of the attorney-client privilege and the absolute work product privilege. The Referee expressed the view that the attorney-client privilege protects only communications between an attorney and a client, but not an attorney's communications with members or agents of her law firm about client matters. In addition, because he was of the view that the communications at issue were not reduced to writing and did not seek an attorney's legal opinions, the Referee concluded that only the qualified work product privilege applied and therefore those communications should be divulged to avoid "unfair[] prejudice" to real parties in interest. As indicated, the trial court issued the recommended order on November 18, 2010.

Fireman's Fund responded with the petition for writ relief that is now before us.10

ISSUES PRESENTED

The pending petition for writ relief raises two very narrow and specific questions. First, is the attorney-client privilege limited to communications between an attorney and his or her client or is it broad enough to cover communications related to a client's matter or interests among and between multiple counsel (or other reasonably necessary parties) who are representing the client? Second, is the absolute work product privilege limited to matters reduced to writing or does it extend to an attorney's impressions, conclusions, opinions, legal research or theories whether or not reduced to writing?

The trial court adopted the narrower view with respect to both privileges. As we explain, this was error.

DISCUSSION

"The appellate court may entertain a petition for extraordinary relief when compulsion to answer a discovery order would violate a privilege." (BP Alaska Exploration, Inc. v. Superior Court (1988) 199 Cal.App.3d 1240, 1249 [245 Cal.Rptr. 682].) Discovery orders are reviewed for an abuse of discretion. (Costco Wholesale Corp. v. Superior Court (2009) 47 Cal.4th 725, 733 [101 Cal.Rptr.3d 758, 219 P.3d 736].) A trial court's application of the wrong legal standard is an abuse of discretion. (Ibid.) In this case, the principal issue raised is whether the trial court applied the proper legal standard with respect to both the attorney-client privilege and the work product privilege. Based on this record, it is clear that it did not.

1. The Attorney-client Privilege Is Not Limited to Communications Directly Between a Client and His or Her Attorney

(1) "[T]he fundamental purpose of the attorney-client privilege is the preservation of the confidential relationship between attorney and client [citation], and the primary harm in the discovery of privileged material is the disruption of that relationship . . . ." (Costco Wholesale Corp. v. Superior Court, supra, 47 Cal.4th at pp. 740-741.)

To effectuate this purpose, the attorney-client privilege, codified at Evidence Code section 954,11 gives a client the right "to refuse to disclose, and to prevent another from disclosing, a confidential communication between client and lawyer." Evidence Code section 952 broadly defines "`confidential communication between client and lawyer'" as "information transmitted between a client and his or her lawyer in the course of that relationship and in confidence by a means which, so far as the client is aware, discloses the information to no third persons other than those who are present to further the interest of the client in the consultation or those to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted, and includes a legal opinion formed and the advice given by the lawyer in the course of that relationship." (Italics added.)

(2) While most instances in which an assertion of the privilege is upheld involve communications between an attorney and client, the statutory language is not so narrow. As noted above, the definition of a protected "confidential communication" includes "a legal opinion formed." "In 1967, Evidence Code section 952 was amended to include within the definition of a confidential communication `a legal opinion formed and the advice given by the lawyer in the course of that relationship.' The comment of the Law Revision Commission to the 1967 amendment makes clear the scope of the amendment. `The express inclusion of "a legal opinion" in the last clause will preclude a possible construction of this section that would leave the attorney's uncommunicated legal opinion—which includes his impressions and conclusions—unprotected by the privilege. Such a construction would virtually destroy the privilege.'" (Lohman v. Superior Court (1978) 81 Cal.App.3d 90, 99 [146 Cal.Rptr. 171].) Thus, legal opinions formed by counsel during representation of the client are protected "confidential communication[s]," even if the opinions have not been transmitted to the client.

(3) Moreover, Evidence Code section 952 provides that a "confidential communication" remains such when it is disclosed "to no third persons other than those who are present to further the interest of the client in the consultation or those to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted." Surely, third persons to whom the information (in this case, an attorney's legal opinions) may be conveyed without destroying confidentiality include other attorneys in the law firm representing the client. Indeed, Evidence Code section 954 emphasizes that the relationship between attorney and client exists between the client and all attorneys employed by the retained law corporation. The Supreme Court has recognized that it is an "everyday reality that attorneys, working together and practicing law in a professional association, share each other's, and their clients', confidential information." (People ex rel. Dept. of Corporations v. SpeeDee Oil Change Systems, Inc. (1999) 20 Cal.4th 1135, 1153-1154 [86 Cal.Rptr.2d 816, 980 P.2d 371].) Such sharing cannot abrogate the privilege protecting an attorney's legal opinions.

(4) The issue also arises as to whether the legal opinions may be shared with a nonattorney agent retained by the attorney to assist with the representation without losing their confidential status. It appears that they can, as such an agent would fall into the category of "those to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted."

Against this framework, we now consider several of the questions asked Attorney Dubbs which are at issue in this proceeding. Questions 6 and 10 asked, "What did you tell Mr. Carlson in order for him to write a personal check to Mr. Chand?" and "Did you explain who Mr. Chand was to Mr. Carlson before he wrote the check?" Both of these questions seek information regarding Dubbs's evaluation of Chand and his possible usefulness to Fireman's Fund's case, as expressed to another attorney at CCP. In other words, they seek from Dubbs her legal opinions, which, as far as the record indicates, were expressed only to another CCP attorney. These opinions are confidential communications, which are protected by the attorney-client privilege.

Question 5 asked Dubbs how Attorney Peterson drafted Chand's declaration without speaking to Chand. This question clearly seeks privileged information, that is, Peterson's legal opinions involved in the drafting of the Chand declaration. The information does not lose its confidential characterization by being shared with Dubbs (or others at the CCP firm) and there is no indication that the information has been shared with anyone else. As such, this question sought information subject to the attorney-client privilege, and an answer should not have been compelled.

Question 7 asked Dubbs to disclose her "discussions" with investigator Pierce regarding "how to pay" Chand $1,000. There is an ambiguity in the question, which makes it impossible to determine whether the question calls for the disclosure of confidential communications. If the question implicates Dubbs's legal opinions regarding Chand, the answer would be privileged, as the fact that Dubbs communicated her opinions to an investigator retained by CCP would not render the opinions unprivileged. However, if the answer to the question simply involves Pierce's communications to Dubbs conveying Chand's desire to be paid and/or the means by which he would prefer to be paid, the privilege would not apply. Chand was not a client of CCP. His communications to CCP's investigator, even if subsequently conveyed to CCP, would not be privileged attorney-client communications.

In sum, questions 5, 6, 10, and possibly 7, sought "confidential communications," including attorney legal opinions, protected by the attorney-client privilege. Attorney Dubbs should not have been compelled to answer these questions. We now turn to a consideration of the work product privilege.

2. The Absolute Work Product Privilege Depends Not on the Existence of a Writing but Rather on the Nature of the Claimed Privileged Matter

(5) As noted above, the work product privilege is currently codified in section 2018.030 (see fn. 7, ante). Subdivision (a) of that section provides an absolute privilege for "[a] writing that reflects an attorney's impressions, conclusions, opinions, or legal research or theories," and subdivision (b) provides a qualified privilege for all attorney work product "other than a writing described in subdivision (a)."12 We will refer to an attorney's "impressions, conclusions, opinions, or legal research and theories" by the shorthand phrase "opinion work product." Based on the statutory language, the trial court concluded that writings encompassing opinion work product are protected by the absolute privilege, but the opinion work product itself, if not reduced to writing, is protected by only a qualified privilege.

While the plain language of this statute is perhaps amenable to the interpretation adopted by the trial court, further investigation of the issue suggests that a different interpretation is also possible. It may be that the Legislature believed that statutory protection was necessary only for written work product, and simply limited the entire statute's scope to writings, as writings were all that needed statutory protection. That is, the absolute privilege was expressly provided for written opinion work product, and the qualified privilege's application to all "other" "work product" was intended to apply to written nonopinion work product. The statutory language is amenable to this interpretation as well.

Moreover, a comparison of section 2018.030 to the federal work product privilege, found at rule 26(b)(3) of the Federal Rules of Civil Procedure (28 U.S.C.), demonstrates the reasonableness of this interpretation. The federal rule provides, in pertinent part, that "documents and tangible things that are prepared in anticipation of litigation or for trial" by a party's attorney are discoverable only when the party seeking discovery shows that it has substantial need for the materials to prepare its case and cannot, without undue hardship, obtain their substantial equivalent by other means. (Ibid.) However, the rule further provides that if discovery of such materials is ordered, the court "must protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of a party's attorney."13 (Fed. Rules Civ. Proc., rule 26(b)(3)(B), 28 U.S.C.) In other words, the Federal Rules of Civil Procedure define work product as "documents and tangible things that are prepared in anticipation of litigation or for trial." The federal rules then provide absolute protection for opinion work product and a qualified protection for all other work product. While the California statute does not expressly define work product at all, the statute's language can be read, as already noted, to suggest a legislative intent that it have application only to written work product.

If this interpretation is correct, it raises a second question: Did the Legislature's restriction of the statutory protection to written work product intend to leave unwritten work product unprotected, or was there reason to believe the Legislature assumed unwritten work product was already protected? To best understand this issue, it is helpful to turn to the case in which the United States Supreme Court first adopted the work product doctrine, Hickman v. Taylor (1947) 329 U.S. 495 [91 L.Ed. 451, 67 S.Ct. 385] (Hickman).

The Hickman case arose out of a lawsuit filed by the family of a man who drowned when a tugboat on which he was working sank. Counsel for the tugboat (and its insurers) took statements from the survivors and other potential witnesses, "with an eye toward the anticipated litigation." (Hickman, supra, 329 U.S. at p. 498.) Counsel for the plaintiff sought discovery of the witness statements and other materials collected by defense counsel in preparation for the lawsuit. (Id. at pp. 498-499.) No showing was made that the witnesses were unavailable to the plaintiff's counsel, and the plaintiff had already obtained discovery from the defendant, so the plaintiff knew the facts on which the defendant planned to rely. (Id. at pp. 508-509.) The Supreme Court stated, "We are thus dealing with an attempt to secure the production of written statements and mental impressions contained in the files and the mind of the attorney . . . without any showing of necessity or any indication or claim that denial of such production would unduly prejudice the preparation of petitioner's case or cause him any hardship or injustice." (Id. at p. 509.) The court concluded that the discovery request contravened the public policy underlying the orderly prosecution and defense of legal claims. "Not even the most liberal of discovery theories can justify unwarranted inquiries into the files and the mental impressions of an attorney." (Id. at p. 510.) The court ultimately concluded that work product may be discoverable in certain circumstances, none of which were present in the case before it. (Id. at pp. 511-513.)

However, although the Supreme Court concluded that written work product may sometimes be discoverable, the court's analysis began from the premise that an attorney's thoughts are inviolate, and the Hickman opinion never suggested that the law should be otherwise. The court stated that an attorney's work "is reflected . . . in interviews, statements, memoranda, correspondence, briefs, mental impressions, personal beliefs, and countless other tangible and intangible ways—aptly though roughly termed . . . the `work product of the lawyer.' Were such materials open to opposing counsel on mere demand, much of what is now put down in writing would remain unwritten. An attorney's thoughts, heretofore inviolate, would not be his own. Inefficiency, unfairness and sharp practices would inevitably develop in the giving of legal advice and in the preparation of cases for trial. The effect on the legal profession would be demoralizing. And the interests of the clients and the cause of justice would be poorly served." (Hickman, supra, 329 U.S. at p. 511, italics added.) In other words, the United States Supreme Court extended protection to written opinion work product because unwritten opinion work product was already inviolate.

(6) We return to section 2018.030. There are three possible interpretations of its language. First, the statute may provide absolute protection to written opinion work product and qualified protection to all other work product, written and unwritten. Second, the statute may provide absolute protection to written opinion work product, qualified protection to written nonopinion work product, and leave unwritten work product unprotected. Third, the statute may provide absolute protection to written opinion work product and qualified protection to written nonopinion work product, with the implicit understanding that unwritten opinion work product is already entitled to absolute protection. We conclude that the third interpretation is the proper one, based on considerations of (a) legislative history; (b) interpretation of the similar federal work product privilege; and (c) avoiding absurdity.

a. Legislative History

The history of the work product privilege in California has been set forth at length in Dowden v. Superior Court (1999) 73 Cal.App.4th 126, 130-133 [86 Cal.Rptr.2d 180]. Key for our purposes are the facts that (1) in the federal system, the work product privilege was adopted by the United States Supreme Court in Hickman and (2) thereafter, the California Supreme Court concluded that, despite the persuasiveness of the Hickman opinion, adoption of a work product privilege in California was a matter for the Legislature, not the courts. (Greyhound Corp. v. Superior Court (1961) 56 Cal.2d 355, 401 [15 Cal.Rptr. 90, 364 P.2d 266].) The result was the enactment, in 1963, of an amendment to then section 2016, which adopted a work product privilege in California.14 (Stats. 1963, ch. 1744, § 1, pp. 3477-3478.) The added language provided, in language very similar to that now found in section 2018.030, as follows: "The work product of an attorney shall not be discoverable unless the court determines that denial of discovery will unfairly prejudice the party seeking discovery in preparing his claim or defense or will result in an injustice, and any writing that reflects an attorney's impressions, conclusions, opinions, or legal research or theories shall not be discoverable under any circumstances."15

References in the legislative history indicate that the Legislature believed that the effect of the statute was to "establish in California substantially the same rule" as Hickman, and the "numerous decisions of other U.S. courts in interpreting and applying the rule." (State Bar of California, letter to Governor Edmund G. Brown, July 2, 1963, p. 2; Mem. entitled "Explanation of Senate Bill 24" in legislative bill file of Sen. James Cobey, May 29, 1963, p. 2.) Thus, the California Legislature appears to have had the intent of adopting the rule of Hickman which, as we discussed above, protected written opinion work product because it assumed unwritten opinion work product was already inviolate.

In addition, the legislative history is replete with indications that the Legislature believed that by enacting the statute, it was providing absolute protection for all opinion work product—not that it was leaving unwritten opinion work product open to discovery (even under a showing of good cause). For example, the Senate Committee on Judiciary explained: "The amendment would limit discovery to protect attorneys and therefore their clients in the preparation and investigation of cases, and specifically would deny discovery of reports and opinions of experts obtained in anticipation of litigation and anything `created' by or for a party or his agent. Under no circumstances could the `mental impressions, conclusions, opinions or legal theories' of an attorney be reached. Recent case law indicates that in view of the legal theory under which such matters might be protected, legislation is necessary to accomplish the purpose of the amendment." (Sen. Com. on Judiciary, Analysis and Final Action on the Measures Considered by this Committee During the 1963 Regular Session of the Legislature, p. 27, italics added.) Other documents indicate that one of the effects of the bill was "to prohibit the discovery of that portion of lawyers' work product reflecting an attorney's impressions, conclusions, and theories." (Sen. James A. Cobey, letter to Governor Edmund G. Brown, July 22, 1963, p. 1; see State Bar of Cal., letter to Governor Edmund G. Brown, July 2, 1963, p. 2.) In short, there is every indication in the legislative history that the California law was intended to absolutely protect opinion work product in every form, and no indication that it was intended to provide lesser protection for unwritten work product.16

b. The Similar Federal Work Product Privilege Is Interpreted Similarly

It is useful to consider the way federal courts have resolved the issue of the protection to be accorded unwritten opinion work product. There are two lines of analysis taken in the federal cases, both of which reach the conclusion that unwritten opinion work product is entitled to absolute protection.

One line of cases takes the position that rule 26(b)(3) of the Federal Rules of Civil Procedure (28 U.S.C.) protects only documents and tangible things, but Hickman itself "provides work-product protection for intangible work product independent of Rule 26(b)(3)." (U.S. v. Deloitte LLP, supra, 610 F.3d at p. 136; see also Ford v. Philips Electronics Instruments Co. (E.D.Pa. 1979) 82 F.R.D. 359, 360 [although the federal rule is limited to documents and tangible things, intangible opinion work product is not otherwise discoverable].) As the California Legislature intended to establish substantially the same rule as Hickman in California, and federal courts have interpreted Hickman to itself provide absolute protection for unwritten opinion work product, this suggests the California law provides similar protection.

The second line of cases acknowledges that the language in Federal Rules of Civil Procedure, rule 26(b)(3) (28 U.S.C.) is limited to written work product, but nonetheless interprets the rule to extend its protection to intangible work product. "[T]he courts have rejected an interpretation of Rule 26(b)(3) that provides protection only for an attorney's mental impressions that are contained in `documents and tangible things.' [Citations.] These decisions make clear that a party cannot discover what an attorney said to a witness in interviewing him or in preparation for his deposition because such statements are likely to reveal the attorney's mental impressions, opinions and theories of the case." (Connolly Data Systems, Inc. v. Victor Technologies, Inc. (S.D.Cal. 1987) 114 F.R.D. 89, 96;17 see also Laxalt v. McClatchy, supra, 116 F.R.D. at p. 441; Phoenix National Corp. v. Bowater United Kingdom Paper Ltd. (N.D.Ga. 1983) 98 F.R.D. 669, 671.) These cases support the conclusion that similar language in California's work product statute should not be read to limit the privilege's protection solely to written work product.

While the federal cases reach their results on different theories, they are in agreement that unwritten opinion work product is absolutely privileged— based on the policy set forth in Hickman. Thus, both lines of cases are of assistance in interpreting the California privilege, and both support the conclusion that unwritten opinion work product is absolutely privileged.

c. Avoiding Absurdity

(7) "A court must construe a statute reasonably, endeavoring to ascertain the legislative intent. If the construction does not result in patently absurd results, we may not construe a statute contrary to its plain language and ostensible intent merely because we disagree with the wisdom thereof." (Lasky, Haas, Cohler & Munter v. Superior Court (1985) 172 Cal.App.3d 264, 279 [218 Cal.Rptr. 205].) Under the trial court's interpretation of the language of section 2018.030, written opinion work product is protected by an absolute privilege, while unwritten opinion work product is protected by only a qualified privilege. Is it patently absurd to provide a greater protection for written opinion work product than unwritten opinion work product? In our view, the answer to that question is yes.

(8) Case law has explained that the work product "doctrine protects the `"mental processes of the attorney, providing a privileged area within which he can analyze and prepare his client's case."'" (2,022 Ranch v. Superior Court (2003) 113 Cal.App.4th 1377, 1390 [7 Cal.Rptr.3d 197].) Yet, an attorney is not provided a privileged area in which to prepare the case when only those attorney opinions which have been reduced to writing are absolutely protected.

Moreover, such an interpretation of the privilege would inevitably result in attorneys documenting their every thought (in order to obtain complete protection for their work product) at the expense of higher client bills for the time taken in documentation, and at the risk of malpractice lawsuits if the failure to document an opinion resulted in its being held discoverable. We cannot conclude that our Legislature intended such absurd results.18

d. Application of Work Product Privilege

(9) Based on the foregoing analysis, we conclude that unwritten opinion work product is entitled to the protection of the absolute work product privilege in California. Having concluded that unwritten opinion work product is absolutely protected under California law, we turn to the deposition questions at issue in this case. (10) As we discussed above, questions 5, 6, and 10 sought the legal opinions of Fireman's Fund's attorneys. As such, while the questions invaded the attorney-client privilege, the questions also sought unwritten opinion work product of Fireman's Fund's attorneys, and therefore ran afoul of the absolute work product privilege. Similarly, question 7 sought the discussions between Dubbs and investigator Pierce regarding how to pay Chand $1,000. To the extent the question sought Dubbs's unwritten opinion work product regarding Chand, the absolute privilege is implicated.19 Question 9 asked Attorney Dubbs which subpoenas she prepared based on any documents received from Chand. This clearly implicates her opinion work product and is therefore subject to the absolute privilege. The motion to compel therefore should have been denied with respect to questions 5, 6, 9, and 10, and part of question 7.

DISPOSITION

The petition for writ of mandate is granted. Upon remand, the trial court is directed to vacate its order of November 18, 2010, and to enter a new and different order sustaining petitioners' objections to deposition questions 5, 6, 9 and 10, and that part of question 7 seeking Attorney Dubbs's opinions with respect to Chand. The trial court (or the Referee pursuant to the trial court's referral and designation orders) shall conduct such further proceedings as may be appropriate and consistent with the views expressed herein. Fireman's Fund shall recover its costs in these appellate proceedings.

Klein, P.J., and Kitching, J., concurred.
