GEMELLO, J.
Does the City Attorney's prior representation of the target of a public investigation in matters substantially related to that investigation require vicarious disqualification of the entire City Attorney's Office? We hold that it does. Public confidence in the administration of justice and the integrity of the bar requires that both the City Attorney and his office be disqualified.
By this holding, we imply no criticism of City Attorney Herrerra's conduct in this matter.
We expressly limit our holding to cases in which the conflicted civil attorney is the head of a public law office. There are sound reasons why automatic disqualification might be inappropriate when the conflicted attorney is anyone else, and why imposition of an assiduously observed ethical screen might suffice to accommodate the weighty competing public and private concerns at stake. We are not called on here to decide, and we do not decide, whether automatic disqualification is required in such cases.
FACTUAL AND PROCEDURAL BACKGROUND
For purposes of this appeal, the material facts are undisputed. In September 2000, Dennis Herrera (Herrera), San Francisco's City Attorney, was still in private practice. Cobra Solutions, Inc. (Cobra) approached him and retained him and his firm to represent it in a range of business matters, including dealings with the City of San Francisco (City) and an ongoing dispute with the City's Department of Building Inspections.
In November 2001, Herrera was elected San Francisco City Attorney and shortly thereafter left private practice.
In September 2001, under Herrera's predecessor, Louise Renne, the San Francisco City Attorney's Office (City Attorney's Office) began an investigation of the City's technology contracting. The investigation turned up evidence that Marcus Armstrong, the head of the City's Department of Building Inspections, had authorized prepayments on a city contract with Government Computer Sales, Inc. (GCSI) in violation of City law, and that GCSI had failed to fulfill the contract. On February 10, 2003, the City sued GCSI, Armstrong, and others, alleging that GCSI paid Armstrong kickbacks through various fictitious business entities in order to have him select GCSI for the contract and authorize illegal prepayments.
Armstrong was subsequently indicted and pleaded guilty to federal mail fraud, wire fraud, and obstruction of justice charges.
In March 2003, further investigation uncovered evidence of payments by Cobra, another City contractor, to Armstrong's fictitious business entities, and in April 2003 the City added Cobra as a defendant in the GCSI lawsuit.
One month later, Cobra moved to disqualify Herrera and the entire City Attorney's Office. It argued that Herrera had previously represented it in matters substantially related to the current lawsuit, and that consequently both Herrera and the City Attorney's Office were barred from representing the City against Cobra. The City Attorney's Office responded that it had instituted an ethical screen immediately upon discovering Cobra's alleged involvement in the kickback scheme. All responsibilities for decisions concerning the matter were passed from Herrera to his chief deputy, Jesse Smith, and Herrera had no further involvement in the case. It also argued that Herrera's prior representation of Cobra was not substantially related to the current litigation, and that disqualification was therefore unnecessary.
In the case before us, the effectiveness of the screen was not tested in the trial court. (See LaSalle Nat. Bank v. Lake County (7th Cir. 1983) 703 F.2d 252 [effectiveness of screen must be capable of evaluation by objective and verifiable evidence at the trial court level].) We make no assumptions about its effectiveness. We note that for 16 months while the City's technology contracting was being investigated, Herrera was the head of the office and no specific institutional mechanisms were in place.
The trial court granted the motion to disqualify Herrera and the City Attorney's Office. Critically important to our analysis are the trial court findings that Herrera had personally represented Cobra, that he had obtained confidential information from Cobra, and that the subject of the prior representation was substantially related to the current lawsuit. The trial court held that as a matter of law disqualification of both Herrera and the City Attorney's Office was required. On appeal, we granted the Attorney General, County of Santa Clara, California State Association of Counties, and League of California Cities leave to appear as amici curiae to address the disqualification standards that should apply to private attorneys who join public law offices.
DISCUSSION
I. Standard of Review
An order disqualifying an attorney is immediately appealable. ( State Water Resources Control Bd. v. Superior Court (2002) 97 Cal.App.4th 907, 913.) The parties disagree over the applicable standard of review. Under the circumstances of this appeal, we review de novo the trial court's order disqualifying the City Attorney's Office.
In general, "a trial court's decision on a disqualification motion is reviewed for abuse of discretion." ( People ex rel. Dept. of Corporations v. SpeeDee Oil Change Systems, Inc. (1999) 20 Cal.4th 1135, 1143 ( SpeeDee Oil).) This entails deferring to the trial court's factual findings whenever supported by substantial evidence. ( Id. at pp. 1143-1144.) Here, despite some initial protestations, the City Attorney's Office concedes that it is not challenging the trial court's factual findings, and concedes that they are supported by substantial evidence. Thus, we take those findings as a given and ask whether as a matter of law they support vicarious disqualification here. ( Id. at p. 1144; Cho v. Superior Court (1995) 39 Cal.App.4th 113, 119.) In doing so, we are mindful of our Supreme Court's warning that "A motion to disqualify a party's counsel may implicate several important interests. Consequently, judges must examine these motions carefully to ensure that literalism does not deny the parties substantial justice." ( SpeeDee Oil, at p. 1144.)
II. Where the Head of a Public Law Office Has a Conflict Arising from an Earlier Private Representation, Vicarious Disqualification Is Required
A. The Duties of Loyalty and Confidentiality
Professional ethics demand that an attorney avoid conflicts of interest in which duties owed to different clients are in opposition. ( Flatt v. Superior Court (1994) 9 Cal.4th 275, 282 fn. 2 ( Flatt); Rules Prof. Conduct, rule 3-310(C).) A conflict of interest may arise from an attorney's simultaneous or successive representation of clients with adverse interests. ( Flatt, at pp. 283-284.) These two situations implicate distinct ethical concerns and public policies. ( Ibid.)
Rule 3-310(C) provides: "A member shall not, without the informed written consent of each client: [¶] (1) Accept representation of more than one client in a matter in which the interests of the clients potentially conflict; or [¶] (2) Accept or continue representation of more than one client in a matter in which the interests of the clients actually conflict; or [¶] (3) Represent a client in a matter and at the same time in a separate matter accept as a client a person or entity whose interest in the first matter is adverse to the client in the first matter."
All rule references are to the Rules of Professional Conduct.
Concurrent representation of clients with adverse interests compromises an attorney's duty of loyalty. "Attorneys have a duty to maintain undivided loyalty to their clients to avoid undermining public confidence in the legal profession and the judicial process. [Citation.] The effective functioning of the fiduciary relationship between attorney and client depends on the client's trust and confidence in counsel. [Citation.]" ( SpeeDee Oil, supra, 20 Cal.4th at p. 1146.) In order to maintain undivided loyalty to clients and preserve public confidence in the legal profession, an attorney must not concurrently represent clients with adverse interests, whether or not the matters are related. ( Id. at pp. 1146-1147; Flatt, supra, 9 Cal.4th at p. 284; Rule 3-310(C)(3).) "A client who learns that his or her lawyer is also representing a litigation adversary, even with respect to a matter wholly unrelated to the one for which counsel was retained, cannot long be expected to sustain the level of confidence and trust in counsel that is one of the foundations of the professional relationship." ( Flatt, at p. 285, emphasis omitted.) With few exceptions, a stringent per se disqualification rule applies to an attorney's simultaneous representation of adverse clients without the clients' consent. ( SpeeDee Oil, at p. 1147; Flatt, at pp. 285-286, fn. 4; State Farm Mutual Automobile Ins. Co. v. Federal Ins. Co. (1999) 72 Cal.App.4th 1422, 1431-1432.)
Successive representation of clients with adverse interests raises slightly different ethical concerns. With successive representation of adversaries, "the chief fiduciary value jeopardized is that of client confidentiality," not loyalty. ( Flatt, supra, 9 Cal.4th at p. 283; accord, SpeeDee Oil, supra, 20 Cal.4th at p. 1146.) The former client's expectation of confidentiality must be preserved to ensure "`the right of every person to freely and fully confer and confide in one having knowledge of the law, and skilled in its practice, in order that the former may have adequate advice and a proper defense.' [Citation.]" ( SpeeDee Oil, at p. 1146, quoting Mitchell v. Superior Court (1984) 37 Cal.3d 591, 599.) The attorney must maintain those confidences inviolate and preserve them at every peril to himself or herself. (Bus. Prof. Code, § 6068, subd. (e).) Because of this duty, an attorney in actual possession of material confidential information from a former client may not represent an adverse party without the former client's consent. ( H.F. Ahmanson Co. v. Salomon Brothers, Inc. (1991) 229 Cal.App.3d 1445, 1452; Rule 3-310(E).)
B. Motions to Disqualify and Successive Representation in the Private Sector
Rule 3-310(E) provides: "A member shall not, without the informed written consent of the client, or former client, accept employment adverse to the client or former client where, by reason of the representation of the client or former client, the member has obtained confidential information material to the employment."
A trial court may disqualify a party's counsel to enforce these ethical standards. ( SpeeDee Oil, supra, 20 Cal.4th at p. 1145; Code Civ. Proc., § 128, subd. (a)(5).) "A trial court's authority to disqualify an attorney derives from the power inherent in every court `[t]o control in furtherance of justice, the conduct of its ministerial officers, and of all other persons in any manner connected with a judicial proceeding before it, in every matter pertaining thereto.' [Citations.]" ( SpeeDee Oil, at p. 1145.) A motion to disqualify an opposing party's counsel implicates the opposing party's freedom to retain counsel of choice, but that freedom must be subordinated when preservation of the duties of loyalty or confidentiality are at stake. The California Supreme Court teaches repeatedly that "[t]he paramount concern must be to preserve public trust in the scrupulous administration of justice and the integrity of the bar. The important right to counsel of one's choice must yield to ethical considerations that affect the fundamental principles of our judicial process." ( Ibid.; see also Comden v. Superior Court (1978) 20 Cal.3d 906, 915.)
In successive representation cases, the "substantial relationship" test mediates between these competing interests. ( Flatt, supra, 9 Cal.4th at p. 283.) Absent a substantial relationship between the subjects of the two representations, the current client's choice of counsel will be honored and the motion to disqualify must be denied. However, if a "substantial relationship between the subjects of the prior and the current representations can be demonstrated, access to confidential information by the attorney in the course of the first representation (relevant, by definition, to the second representation) is presumed and disqualification of the attorney's representation of the second client is mandatory." ( Flatt, supra, 9 Cal.4th at p. 283; accord, SpeeDee Oil, supra, 20 Cal.4th at p. 1146; see also Rosenfeld Construction Co. v. Superior Court (1991) 235 Cal.App.3d 566, 575 ["`If a substantial relationship is established, the discussion should ordinarily end. The rights and interests of the former client will prevail. Conflict would be presumed; disqualification will be ordered.'"].) This mandatory rule applies unless the court finds that other countervailing factors exist, such as tactical abuse underlying the disqualification motion. ( In re Marriage of Zimmerman (1993) 16 Cal.App.4th 556, 562.)
In its briefing and oral argument, the City emphasizes that the threshold for "substantially related" is minimal. There is no support for this proposition in the law or on the record before us. The City does not challenge the trial court finding that Herrera's prior representation of Cobra was "substantially related." The City may not imply that Herrera's prior representation was de minimis in order to argue directly or indirectly that Herrera's involvement is insufficient to create a conflict of interest imputed to his staff.
In the private sector, disqualification extends from the affected attorney to her entire firm. The "presumption that an attorney has access to privileged and confidential matters relevant to a subsequent representation extends the attorney's disqualification vicariously to the attorney's entire firm." ( SpeeDee Oil, supra, 20 Cal.4th at p. 1146.) Vicarious disqualification is required "to assure the preservation of [the client's] confidences and the integrity of the judicial process." ( Id. at p. 1156.) When a client has disclosed confidences to an attorney who later becomes its litigation opponent, "[n]o amount of assurances or screening procedures, no `cone of silence,' could ever convince the opposing party that the confidences would not be used to its disadvantage." ( Cho v. Superior Court, supra, 39 Cal.App.4th at p. 125.) "No one could have confidence in the integrity of a legal process in which this is permitted to occur without the parties' consent." ( Ibid.; see Adams v. Aerojet-General Corp. (2001) 86 Cal.App.4th 1324, 1334-1335.) The public cannot be left to believe that attorneys within a firm might discuss matters despite an ethical screen and that the law would turn a blind eye to such presumed disclosures. Consequently, a prophylactic vicarious disqualification rule extends to the entire law firm.
C. Successive Representation in the Public Sector
The foregoing general rules have been developed in the context of concurrent and subsequent representation in the private sector. Where public sector representation is involved, different interests are at stake, and so different rules may apply.
In Chambers v. Superior Court (1981) 121 Cal.App.3d 893 ( Chambers), the leading case on subsequent representation in the private sector after working in the public sector, the court found it an abuse of discretion to impose vicarious disqualification. ( Id. at p. 894.) Chambers involved a tort action against the State of California; the State moved to disqualify the plaintiffs' firm because one of its members had previously represented the State in similar matters. ( Id. at p. 895.) The court relied heavily on 1975 ABA Formal Opinion 342, which held that vicarious disqualification of a private firm based on a member's public sector work is not required under the ABA's Code of Professional Responsibility. Instead, disqualification of the individual attorney and an ethical screen around that attorney may suffice. ( Id. at pp. 898-899, 903.)
ABA Formal Opinion 342 and Chambers highlighted three reasons for allowing more limited prophylactic measures against the breach of confidences for attorneys coming from the public sector. First, vicarious disqualification impinges on a client's ability to retain the counsel of her choice (a consideration which, we note, is equally present in private sector cases). Second, vicarious disqualification might unduly limit a former government lawyer's employment prospects because she carries the taint of her prior work. Third, vicarious disqualification might hamper government recruiting efforts, as able lawyers elect not to do work that would later limit their employment prospects. ( Chambers v. Superior Court, supra, 121 Cal.App.3d at p. 899.)
The extent to which these latter considerations enumerated in Chambers are any more manifest in public-to-private cases than they are in private-to-private cases is unclear. Attorneys leaving private firms like attorneys leaving public offices carry with them a taint for all substantially related matters in which they participated. It may well be that vicarious disqualification is an overbroad response to the problem of protecting client confidences and that it needs to be reconsidered. If so, it is not readily apparent why the disqualification is broader in private-to-private migration than in public-to-private migration or why the reasons identified in Chambers are sufficient by themselves to support different rules.
Subsequent cases have confirmed that where migration from public service to private service is involved, vicarious disqualification is not automatically required. In Higdon v. Superior Court (1991) 227 Cal.App.3d 1667, a court commissioner held hearings in two divorce cases, then left public service to join a firm representing one of the parties. The trial court ordered vicarious disqualification of the firm, but the court of appeal reversed the order as an abuse of discretion. It concluded that so long as an ethical screen was observed, no vicarious disqualification was needed. ( Id. at p. 1680.)
Cases involving migration from one public office to another public office similarly have countenanced more limited measures to protect client confidences. In Chadwick v. Superior Court (1980) 106 Cal.App.3d 108, a public defender joined the district attorney's office, and his former clients moved to disqualify the entire district attorney's office, notwithstanding the institution of an ethical screen. The court refused, exercising "particular caution" in declining to extend disqualification from the attorney to the office as a whole. ( Id. at p. 115.) In particular, the court noted that the migrating attorney had no policy or personnel evaluation authority in the district attorney's office. ( Id. at pp. 112-113, 121.) Like the court in Chambers, it relied on ABA Formal Opinion 342 for the proposition that vicarious disqualification does not apply to government lawyers. ( Id. at p. 117.) It emphasized that the financial interests of government lawyers are different: because they are not dependent on each other for their compensation, there may be less incentive to disclose confidential information. It accepted the possibility that in some cases, the structure of government offices might dispel the presumption that information would flow freely. It also emphasized that prosecutors must seek justice, not just convictions. ( Ibid.)
The City Attorney's Office points to two other reasons for applying a different rule in public sector cases: cost and specialization. First, disqualification raises the cost of a given civil or criminal prosecution, and this higher cost may warrant proceeding with caution before disqualifying public sector attorneys and accepting ethical screens as sufficient in a broader category of cases. (See People v. Christian (1996) 41 Cal.App.4th 986, 998.) "Disqualifications of public counsel can result in increased public expenditures for legal representation, and `there is the potential for a substantially increased call upon an already severely strained tax base.'" ( In re Lee G. (1991) 1 Cal.App.4th 17, 28, quoting People v. Municipal Court (Byars) (1978) 77 Cal.App.3d 294, 301.) This first concern goes beyond protection of the public fisc. Because disqualification can significantly raise the cost of prosecution, it changes the cost-benefit analysis of the decision whether to proceed with a given civil prosecution, and raises the possibility that defendants who threaten or obtain vicarious disqualification may avoid prosecution entirely. A broad disqualification rule for public sector attorneys is thus particularly susceptible to tactical abuse.
Second, disqualification of public sector attorneys has the potential to deprive the client of an attorney highly skilled in a particular area of the law, especially when the public law office has a unit with extensive experience in handling a particular sort of public law case. ( In re Lee, supra, 1 Cal.App.4th at p. 28.)
D. Application of the Disqualification Rules to a Public Head of Office
To date, California civil cases have dealt exclusively with migration from private office to private office, from public office to private office, and from public office to public office. None have addressed the fourth possibility: migration from private office to public office. Thus, none of the foregoing cases answer the question debated by the parties and amici: what measures must be employed when an attorney leaves private practice to join a public law office and the public law office then initiates substantially related litigation against the attorney's former client? Cobra argues that the presumption of vicarious disqualification applicable to private-private migration should extend to private-public migration. The City Attorney's Office, Attorney General, and local government amici argue that the allowance for ethical screens made in public-to-private and public-to-public migration cases should extend here.
To decide this case, we need not determine what the general rule should be, because this case involves a unique subset of private-public migration in which the attorney leaves private practice to become the head of a public law office. Where the attorney leaves private practice to become the head of a public law office, we hold that vicarious disqualification of the entire public law office generally is required in all matters substantially related to the head of office's earlier private representations. We are not called upon to decide whether an ethical screen or some other lesser prophylactic measure might suffice when the migrating attorney assumes a subordinate position in the public law office.
We qualify the rule to exclude the situation where the former client has inexcusably postponed making a motion to disqualify its former counsel, resulting in prejudice to the current client. In that situation, the trial court must have discretion to deny the motion. ( River West, Inc. v. Nickel (1987) 188 Cal.App.3d 1297, 1309.)
When the disqualified attorney is the head of a public law office, it raises special concerns that an ethical screen cannot adequately address. Younger v. Superior Court (1978) 77 Cal.App.3d 892 ( Younger) illustrates these problems well. In Younger, a defense attorney left private practice to become the third-highest ranking prosecutor in the Los Angeles County District Attorney's Office. ( Id. at p. 895.) The court acknowledged that the district attorney's office had in place an effective ethical screen excluding the affected attorney from involvement in the prosecution of his former clients or those of his former firm. ( Id. at pp. 896-897.) Nevertheless, it offered three reasons why vicarious disqualification of the entire district attorney's office was required. First, the disqualified attorney had an ongoing say in prosecutorial policies, policies that could affect (intentionally or otherwise) the manner in which his former clients were prosecuted. Second, the attorney had the power to review the performance of those below him in the office, power that might influence how his subordinates prosecuted his former clients. Third, the court found that an ethical screen could not eliminate inevitable public suspicions about how the disqualified attorney's presence might affect the treatment of his former clients. ( Id. at p. 897.) Consequently, despite the cost that special counsel might entail ( id. at p. 894), the court found vicarious disqualification necessary.
Two other criminal cases premised on a head of office attorney's personal conflict of interest identify similar concerns. In People v. Lepe (1985) 164 Cal.App.3d 685, the district attorney, Thomas Storey, had represented the defendant in two related criminal cases. The defense attorney had informed the trial court that it planned to challenge the prior convictions on the basis that the District Attorney's prior representation was incompetent. The court of appeal upheld the trial court's vicarious disqualification of the entire office. As in Younger, the district attorney's residual power over the office ensured that measures short of disqualification would not suffice: "As the deputies are hired by Storey, promoted by Storey and fired by Storey, we cannot say the office can be sanitized such to assume the deputy who prosecutes the case will not be influenced by the considerations that bar Storey himself from participation in the case." ( Id. at p. 689.) In addition to the duty to maintain a former client's confidences, the case implicates the attorney's duty not to undertake representation that is adverse to the attorney's personal interests. Given Storey's personal interest in the competency of his prior representation in combination with his position of power in the office, it strained credibility that his office would not be influenced.
In People v. Choi (2000) 80 Cal.App.4th 476, the defendant was charged with murder; the district attorney believed the murder was related to a second murder, that of the district attorney's close personal friend. ( Id. at p. 478.) The trial court initially denied a motion to disqualify the district attorney's office, in light of an ethical wall barring the district attorney from participation in the case, but subsequently with the admission of additional evidence of the district attorney's emotional involvement in the case, a different judge granted the renewed motion. ( Id. at pp. 478-480.) The court of appeal affirmed, in part because of evidence that the ethical wall was not being strictly observed, and in part because of the recognition that "deputy district attorneys serve at the will of the district attorney." ( Id. at p. 483.) Because they are "hired, evaluated, and promoted by the district attorney," there is an unavoidable potential for bias, notwithstanding any ethical wall. ( Ibid.) Choi, like Lepe, implicates the district attorney's personal conflict of interest, that is, his interest in bringing his close friend's murderer to justice.
In 1980, the Legislature passed Penal Code section 1424, which significantly restricts the availability of disqualification in criminal cases. Thus, Younger is no longer good law in the criminal context. Nevertheless, the concerns present in Younger, Lepe, and Choi are present to an equal degree in this civil case. As the head of the City Attorney's Office, Herrera has the power to set agency policy and to influence the prospects of those who will handle this matter.
Penal Code section 1424, subdivision (a)(1) provides that a motion to recuse a district attorney "may not be granted unless the evidence shows that a conflict of interest exists that would render it unlikely that defendant would receive a fair trial." (Pen. Code, § 1424, subd. (a)(1), added by Stats. 1980, ch. 780, § 1.)
We note that Chadwick v. Superior Court, supra, 106 Cal.App.3d 108, relied upon by the City Attorney's Office in its argument for allowance of an ethical screen, expressly distinguished Younger on the basis that the screened attorney in Chadwick had no "policy or personnel evaluation authority." ( Chadwick v. Superior Court, supra, 106 Cal.App.3d at p. 121.) Here, Herrera's position makes this case analogous to Younger, not Chadwick.
Similarly, in People v. Christian, supra, 41 Cal.App.4th at p. 999, although the county public defender was nominally in charge of both the Public Defender Office that represented one of the defendants and the Alternate Defender Office that represented a co-defendant, the county public defender had no supervisorial or disciplinary authority over the Alternate Defender attorneys.
At the intersection of law and politics, where this head of office case lies, the preservation of the public trust in the scrupulous administration of justice and the integrity of the bar must be the paramount concern. In the City Attorney's prosecution of a former client for fraud, the public cannot be left to wonder whether their top civil lawyer is vigorously representing their interests, maintaining professional objectivity, and keeping inviolate his former clients' confidences. We can ill afford the shades of doubt about the rectitude of our elected officials and our lawyers who are behind a screen. The stakes are too high for the politician's career, for the citizens who deserve his unwavering loyalty, and for the former clients who trust him to maintain their confidences. Like the dissent, we believe that lawyers take their ethical responsibilities seriously. And, as a lawyer, the City Attorney has ethical responsibilities both to his former client and to the public.
The possibility that the City Attorney's former client might be prosecuted for civil fraud by the City Attorney's Office may test public faith in the integrity of the judicial system, raising the specter of perceptions that the former client will be treated more leniently because of its connections, or more harshly because of leaked confidences. Neither perception is consistent with the notion that the power of the state to prosecute fraud will be exercised in an even-handed and impartial manner.
We agree with the City Attorney's Office that reasons exist to support a narrower disqualification rule in public sector cases. (See ante Part II.C.) Those reasons are insufficient when the City Attorney himself is the disqualified attorney. An ethical screen alone cannot suffice here. The City Attorney cannot screen out all his responsibilities for setting office policy and reviewing the performance of his attorney staff.
We recognize that disqualification in the criminal and civil contexts is quite different, and that Younger, Lepe, and Choi thus are not precisely analogous. However, this point does not help the City Attorney's Office. Disqualification is much harder to obtain in criminal cases than in civil cases. (See Pen. Code, § 1424.) Since 1980, the Legislature has not enacted any civil statute paralleling Penal Code section 1424. The willingness of courts to vicariously disqualify an entire office when a higher-up or the head of the office is involved, even in the criminal context, suggests that where the head of the office has a conflict in the civil context, vicarious disqualification must follow.
We readily acknowledge that disqualification may present a hardship for the City Attorney's Office in this case, as in every case where a public law office is disqualified. We do not take this concern lightly. However, the trial court's findings preclude any conclusion that the motion was filed as an abusive litigation tactic or that Cobra delayed unduly in bringing its motion. Consequently, as a matter of law it was proper to impose vicarious disqualification.
We cannot agree with the dissent's conclusion that to avoid the monetary cost of outside counsel, "the government would inevitably curtail enforcement of its legal interests in some circumstances, providing an incentive for the filing of motions to disqualify." First, we have no empirical data about the number of cases where the head of office is or would be disqualified. Second, although it is certainly true that there is an out-of-pocket cost to retaining outside counsel, the true cost is less than the out-of-pocket cost. The City Attorney's Office, once freed from the responsibility for the conflicted case would reassign the previously allocated attorney resources to an additional case.
Amici express concern that a blanket rule of vicarious disqualification for private-public migration cases would hinder the ability of public law offices across the state to recruit and retain talented lawyers and effectively defend the public interest. The trial court's order adopted such a rule; we do not. It remains to be seen whether our more limited ruling, confined to the heads of public law offices, will pose any serious hardship. We reject the notion that there will be a critical disincentive to talented and experienced attorneys seeking election or appointment to positions as head of a public office. We are unwilling to assume in the absence of any evidence that the fear that a significant number of an attorney-candidate's former clients will be prosecuted by the office influences the decision of a potential candidate or the electorate. A strict rule of vicarious disqualification may well be a positive factor in the decision of an experienced private attorney to seek a position as head of a public office. Free from the potential conflicts of loyalties between former clients and the current client and relieved of the hazards of setting office litigation policy while screening out litigation substantially related to his earlier representation of former clients, the attorney-candidate can assume office less encumbered. Because vicarious disqualification remains the presumptive rule, and because conflicts involving the head of a public law office pose problems not readily addressed by an ethical screen alone, we decline to depart from that rule in this case.
Cobra has requested judicial notice of certain public statements made by the City Attorney's Office, and has moved to strike a City Attorney's Office declaration filed in the trial court as part of its motion to stay proceedings pending appeal. The statements and the declaration have no bearing on the issues we decide. We deny the request for judicial notice and grant the motion to strike. (See Mangini v. R.J. Reynolds Tobacco Co. (1994) 7 Cal.4th 1057, 1063.)
DISPOSITION
The modification does not affect the judgment.
The order disqualifying the City Attorney's Office is affirmed.
We concur.
