OPINION
WELLFORD, Circuit Judge.
Plaintiffs filed a stockholder’s derivative action on behalf of the corporation involved in this controversy, Perrigo Company (“Perrigo”), which has its principal place of business in Allegan County, Michigan. Plaintiffs, non-residents of Michigan, brought this suit based on diversity of citizenship. See 28 U.SkC. § 1332(a)(2). The principal defendants are present or former directors, officers, or controlling shareholders of Perrigo. Other defendants are securities investment companies designated “underwriter defendants.” Perrigo now petitions this court to issue a writ of mandamus vacating a previous order of the district court and preventing the district court from ordering production of a report which Perrigo claims is privileged material. The following background information is necessary to the disposition of this petition.
In the underlying derivative suit; plaintiffs claim (among other things) that the defern dants’ actions constituted concealment of true facts regarding the corporation and its financial condition, breach of fiduciary duty, wrongful insider trading.of Perrigo stock, and absence of good faith with respect to a large sale (“a registered public offering”) of Perrigo shares listed on a public stock exchange. It is asserted that those actions profited the individual selling shareholders, directors, and officers at the expense of the corporation and, consequently, to the detriment of the shareholders generally. The complaint refers to a related but separate securities fraud lawsuit, which was brought as a class action and involves substantially the same parties and the same alleged misconduct at issue here. Picard Chemical Inc. Plan v. Perrigo Co., No. 95-CV-141 (W.D.Mich.) (hereinafter referred to as “the class action” or “the securities action”).
The plaintiffs claim that the defendant directors were dominated by defendants Michael J. Jandernoa and Henry L: Hillman (Perrigo’s Chief Executive Officer and alleged controlling shareholder, respectively), who allegedly were the principal beneficiaries of the improper and/or illegal activities. They claim that their derivative suit is necessary because the corporation refused to take the appropriate action against the wrongdoers despite its knowledge of the situation.
Perrigo filed a motion to dismiss the derivative lawsuit pursuant to M.C.L. § 450.1495. That section of the Michigan Business Corporation Act provides:
(1) The court shall dismiss a derivative proceeding if, on motion by the corporation, the court finds that 1 of the groups specified in subsection (2) has made a determination in good faith after conducting a reasonable investigation upon which its conclusions are based that the maintenance of the derivative proceeding is not in the best interests of the corporation ... If the determination is made pursuant to subsection (2)(c) or (d), the plaintiff shall have the burden of proving that the determination was not made in good faith or that the investigation was not reasonable. [433]*433(2) A determination under subsection (1) may be made by any 1 of the following:
(d) By all disinterested independent directors.
M.C.L. § 450.1495. The factual basis for the motion was that Perrigo’s only allegedly disinterested independent director, Peter Formanek, had conducted a four-month investigation and had determined that maintenance of the derivative action was not in Perrigo’s best interests. To help conduct his investigation, Fopmanek retained the assistance of an independent .legal counsel. Formanek, with the assistance of counsel, prepared a 198-page Report (“the Report”) that details his findings and conclusions regarding the desirability of maintaining the derivative lawsuit. Among other things, Formanek concluded that there was no deception of the market, intentionally or negligently, during the period before, during, and immediately after an October 1993 secondary public offering. He concluded that he did not believe that Perrigo would likely prevail on any of its potential derivative claims relating to the class action, so such claims should not be pursued.
Perrigo relied on Formanek’s recommendation as the basis for its motion to dismiss. Faced with having to prove that Formanek’s decision was not in good faith or was not based on a reasonable investigation, plaintiffs sought production of the Report. Perrigo refused to produce it, however, claiming that it was protected by work-product immunity and the attorney-client privilege. The district court addressed the issue for the first time in its opinion dated July 22, 1996. See Kearney v. Jandernoa, 934 F.Supp. 863 (W.D.Mich.1996). It held that any attorney-client privilege was waived when Perrigo relied upon the Report in seeking dismissal. However, the court further held that the waiver did not extend to other parties, such as the plaintiffs in the class action lawsuit. Therefore, the Report could be used only by the derivative plaintiffs in responding to the motion to dismiss.
Perrigo moved to clarify and modify the July order and opinion.. On November 8, 1996, the district court entered an order modifying in part the July order by. vacating the “waiver”, analysis and finding instead that the plaintiffs had established a substantial need for the Report and that undue hardship would result from the court denying the plaintiffs the Report.1 Kearney v. Jandernoa, 949 F.Supp. 510 (W.D.Mich.1996). The court referred to and incorporated its analysis in an opinion entered at about the same time in the class action. Picard Chemical Inc. Profit Sharing Plan v. Perrigo Co., 951 F.Supp. 679 (W.D.Mich.1996). Because the Picard opinion is the basis for the holding in the derivative action, a brief summary is pertinent to the instant petition for mandamus.
In Picard, the class action plaintiffs sought production of the Report from Perrigo. The district court held that the Report was protected by the attorney-client privilege and work-product immunity. The court found specifically that “Perrigo has waived neither the privilege nor the immunity in the class action suit with respect to the Report.” Id. at 693. For the plaintiffs in the class action to obtain the Report, the court found, they must show substantial need and undue hardship. They could not do so, the court held, because they had other means of discovering the information in the Report.2 Therefore, only the derivative plaintiffs were entitled to the Report.
The court went on, however, to discuss the policies behind public access to court records, reasoning that “[a] judicial record must have a role in the adjudication process in order to be accessed by the public.” Id. at 690 (citing Joy v. North, 692 F.2d 880, 893 (2d Cir. 1982)). After reviewing the pertinent case law, the court said:
[Ojnce the Report is submitted to this Court to induce reliance upon the Report, the public interest in open adjudication outweighs the interests underlying the attorney-client privilege and work product immunity. Therefore, although the Report [434]*434is protected by both the ■ attorney-client privilege and work product immunity, the Report will have to be disclosed- to the public once the Report is submitted to the Court for - this Court’s determination of whether Formanek made a good faith judgment after a reasonable investigation.
Id. at 692. The court determined that “[t]his ruling gives Perrigo control of whether and when the Report will be submitted and become part of the public record.” Id. The district court opined that Perrigo could withdraw its motion to dismiss if it feared public access, or it could wait until the conclusion of all discovery in the derivative action in determining whether it chose to submit the Report to the court in the class action. Id.
As stated before, the district court altered its reasoning in the instant derivative action “for the reasons set forth” in the Picard order. Kearney, 949 F.Supp. at 511. It maintained its holding that the Report was protected by the attorney-client privilege and work product immunity, but it found that the derivative plaintiffs were entitled to the Report because, unlike the class action plaintiffs, they could establish substantial need and undue hardship. ■ In vacating the “waiver” analysis, the court found that a determination regarding waiver was unnecessary in light of its finding of hardship. The court concluded that the derivative “plaintiffs, and only [the derivative] plaintiffs are entitled access to the Report.” Id. at 512.
That order did not put the issue to rest. When other defendants in the derivative action also sought disclosure of the Report, the district court entered an order allowing them access provided the parties entered into a stipulated protective order which would protect the contents of the Report in a manner consistent with the November 1996 Picard order. The parties submitted such a protective order in February of 1997. The order governs the treatment of the Report once it is released to the plaintiffs, but not once it is incorporated into court pleadings.
Still wishing to keep the Report under wraps, Perrigo filed a new motion to dismiss. Although Perrigo claims that this motion raises new grounds, a careful reading of the motion shows that the Report and what plaintiffs must show to overcome it remain the primary issues. - Perrigo‘also moved to modify the November 1996 opinion, or, alternatively, to certify the question of law to the Michigan Supreme Court.
On March 14, 1997, the district court denied defendant’s motion for reconsideration. The court reiterated its holdings and again directed Perrigo to provide the plaintiffs with a copy of the Report. The court noted:
Once Plaintiffs obtain the Formanek Report, they will determine whether or not the Report will be submitted to the Court with their response to either or both of Perrigo’s pending motions [to dismiss]. However, there are still open questions of whether this case will be resolved between the parties after Plaintiffs have seen the Formanek Report or whether the Report will be submitted by either side. In any event, if and when the Report is submitted by either side in order to induce reliance by this Court, it will become a public record for the reasons previously stated by this Court.
Although the court found here that it was questionable “whether the Report [would] be submitted by either side,” the court made plain in the Picard order that Perrigo’s submission of the Report “must occur at some point before this Court rules on Perrigo’s motion,” and that Perrigo’s submission will “make the Report part of this Court’s judicial records,” i.e., Perrigo will have waived its rights at that time. Picard, 951 F.Supp. at 691. Consequently, Perrigo was faced with choosing to maintain its motion to dismiss but waive any rights in the Report, or withdraw its motion to protect its privilege and immunity in the Report. Perrigo moved for an interlocutory appeal or to stay the proceedings pending a petition for a writ of mandamus, The district court’s final order denying those motions was entered on March 31, 1997. The court ordered Perrigo either to deliver the Report to plaintiffs within 14 days or its motions to dismiss would be stricken. The instant petition and emergency motion for stay followed. We granted the stay pending the disposition of the merits of the petition for mandamus relief.

ANALYSIS
Mandamus relief is an extraordinary remedy, only infrequently utilized by this court. Our review of petitions for mandamus relief are usually limited to “questions of unusual importance necessary to the economical and efficient administration of justice,” or “important issues of first impression.” EEOC v. K-Mart Corp., 694 F.2d 1055, 1061 (6th Cir.1982); see also FDIC v. Ernst & Whinney, 921 F.2d 83, 85 (6th Cir. 1990). We have recently discussed the framework to apply in cases such as this one in In Re Chimenti, 79 F.3d 534 (6th Cir. 1996). There, quoting from In re School Asbestos Litigation, 977 F.2d 764, 773 (3d Cir.1992), we stated that we were in favor of a “flexible” rather than a “rigid” approach:
Some flexibility is required if the extraordinary writ is to remain available in extraordinary situations. “The writ is a safety valve (one of several safety valves, in fact) in the final-judgment rule, and its proper use cannot be wholly reduced to formula.”
Chimenti, 79 F.3d at 539 (quoting In re School Asbestos Litigation, 977 F.2d at 773). Chimenti reiterated now familiar factors to consider set forth in In re Bendectin Products Liability Litigation, 749 F.2d 300, 304 (6th Cir.1984):
(1) The party seeking the writ has no other adequate means, such as direct appeal, to attain the relief desired.
(2) The petitioner will be damaged or prejudiced in a way not correctable on appeal. (This guideline is closely related to the first.)
(3) The district court’s order is clearly erroneous as a matter of law.
(4) The district court’s order is an oft-repeated error, or manifests a persistent disregard of the federal rules.
(5) The district court’s order raises new and important problems, or issues of law of first impression.
Chimenti, 79 F.3d at 540. Chimenti, however, pointed out that “Bendectin did not require that every element be met, observing that the factors would often be balanced in opposition to each other.” Id.; see also In re NLO Inc., 5 F.3d 154, 156 (6th Cir.1993).
The district court briefly described the Report involved:
To assist in his investigation and report, Mr. Formanek hired Anton R. Yalukas and the law firm of Jenner & Block of Chicago, Illinois. On December. 15, 1995, Mr. Formanek rendered his report. The Court has read portions of the report and scanned .the entire-report. The report contains a detailed factual and legal analysis of the securities fraud claims alleged in the securities fraud case currently pending before this Court. The report discusses interviews that Mr. Formanek’s counsel had with employees of Perrigo, and it also discusses legal theories which are relevant to the securities fraud action. The report concludes “that it would not be in Perrigo Company’s best interest, at this time, to pursue any of the three derivative claims described in the Demand.... ” (Formanek Report at 198.)
Kearney v. Jandernoa, 934 F.Supp. 863, 865 (W.D.Mich.1996). The district court made the following observations as to whether the Report was privileged within the meaning of the statute:
Perrigo argues that there can be adequate discovery and resolution of these issues without permitting the plaintiffs access to the report itself. This Court disagrees. In fact, the report will probably be the best evidence of Mr. Formanek’s good faith and the adequacy of his investigation, or lack thereof. Certainly, this Court will want to have the report before it when it rules upon Perrigo’s motion to dismiss. Moreover, this Court will not rule on the motion to dismiss in reliance upon the determination contained in the report unless plaintiffs have had the opportunity to read and comment upon the report. Therefore, even if there is work product protection for the report, there is good cause to disclose the report to the derivative plaintiffs during discovery so that the derivative plaintiffs can properly prepare their response to Perrigo’s motion to dismiss under Section 495.
[436]*436As to Perrigo’s claim that the report is protected by Perrigo’s attorney-client privilege, this Court disagrees. The key point of distinction between the instant case and the cases cited by Perrigo is that Mr. Formanek’s report is not simply submitted to Perrigo or an independent committee of Perrigo in order to enable it or them to make a recommendation or decision regarding possible wrongdoing of corporate officers or directors, indemnification, or the defense of an action. Rather, the determination contained in the report is being submitted to the Court under Section 495 as a complete and substantive defense to the derivative claims.
Id. at 866 (emphasis', in original).
We note that several cases involving discovery issues have determined that this extraordinary remedy was warranted. In one somewhat analogous case, the court issued a petitioner mandamus relief to vacate a district court order which permitted plaintiffs’ counsel to examine documents protected by attorney-client privilege. Chase Manhattan Bank, N.A. v. Turner & Newall, 964 F.2d 159 (2d Cir.1992). Among other things, Turner & Newall stated:
Unlike other circuits, we have rarely used the extraordinary writ of mandamus to overturn a discovery order involving a claim of privilege. See In re Weisman, 835 F.2d 23, 26 n. 3 (2d Cir.1987); see also 16 C. Wright, A. Miller, & E. Cooper et al., Federal Practice and Procedure § 3935, at n. 20 (1977 & Supp.1991) (citing cases that used mandamus to review claims of privilege).
Id. at 163 (emphasis added). Yet, emphasizing the importance of the attorney-client privilege, the court issued a mandamus in the dispute, noting:
In the case of the attorney-client privilege, however, a litigant claiming the privilege would probably prefer almost anyone other than adversary counsel.to review the documents in question: The attorneys’eyes-only condition simply does not limit disclosure to persons whose knowledge of the confidential communication is not material to the purpose of the privilege. To the contrary, it allows- one kind of critical disclosure — to opposing counsel in litigation — that the privilege was designed to prevent.
The privilege rests on the belief that in an adversary system, a client’s full disclosure to an attorney is a necessary predicate to skillful advocacy and fully informed legal advice. The existence of the privilege thus allows attorneys to assure clients that any information given to their attorneys will remain confidential.
Id. at 164, 165. Mandamus in that case was deemed to be the only adequate means to obtain the relief requested, to avoid prejudice not otherwise correctable, and because the issue involved was deemed particularly important. Another court has similarly stated:
Mandamus may properly be used as a means of immediate appellate review of orders compelling the disclosure of documents and information claimed to be protected from disclosure by privilege or other interests in confidentiality. Haines v. Liggett Group Inc., 975 F.2d 81, 89 (3d Cir.1992); Cipollone v. Liggett Group, Inc., 785 F.2d 1108, 1118 (3d Cir.1986); Sporck v. Peil, 759 F.2d 312, 314, 315 (3d Cir. 1985), cert. denied, 474 U.S. 903, 106 S.Ct. 232, 88 L.Ed.2d 230; Bogosian v. Gulf Oil Corp., 738 F.2d 587, 592 (3d Cir.1984). See also,. Chase Manhattan Bank, N.A. v. Turner & Newall, PLC, 964 F.2d 159 (2d Cir.1992); In re von Bulow, 828 F.2d 94 (2d Cir.1987). We find that the petitioners have no other adequate means to attain relief from the district court’s order that compels the disclosure of privileged information and work product.
Rhone-Poulenc Rorer Inc. v. Home Indem. Co., 32 F.3d 851, 861 (3d Cir.1994).
The plaintiffs, on the other hand, rely upon another case which involved a shareholder’s derivative action and the effect of the recommendation of a “special litigation committee” that the corporation not pursue a shareholder suit. Joy v. North, 692 F.2d 880 (2d Cir.1982). The Joy court discussed the business judgment rule and held for a broad role for judicial inquiry in reviewing such -a rec[437]*437ommendation, not limiting scrutiny “to the good faith, thoroughness and independence of the special litigation committee.” Id. at 889. We note, however, that the court in Joy applied Connecticut law, which emphasizes “traditional fiduciary obligation.” Connecticut had not adopted the Michigan statute which is presently before us.
Turning to the framework for considering mandamus in this circuit, we conclude that Perrigo has no adequate means to attain the discovery relief it seeks except by mandamus, and that it may otherwise be prejudiced by disclosure of the privileged Report. In balancing these factors, we believe that this case presents a situation in which mandamus is appropriate, adopting this court’s more flexible approach. We find, as have several courts, that forced disclosure of privileged material may bring about irreparable harm. The corporate privilege presents special problems in this situation.
When the client is a corporation, special problems arise in applying the privilege. As fictitious entities, corporations can seek and receive legal advice and communicate with counsel only through individuals empowered to act on behalf of the corporation. See Commodity Futures Trading Commission v. Weintraub, 471 U.S. 343, 348, 105 S.Ct. 1986, 1990, 85 L.Ed.2d 372 (1985).
In Upjohn v. United States, 449 U.S. 383, 101 S.Ct. 677, 66 L.Ed.2d 584 (1981), the Supreme Court addressed the issue of the proper scope of the attorney-client privilege in the corporate setting. Rejecting the “control group” test, the Court held that the privilege applies to communications by any corporate employee regardless of position when the communications concern matters within the scope of the employee’s corporate duties and the employee is aware that the information is being furnished to enable the attorney to provide legal advice to the corporation. 449 U.S. at 394, 101 S.Ct. at 685.
Admiral Ins. Co. v. U.S. Dist. Court for Dist. of Ariz., 881 F.2d 1486, 1492 (9th Cir.1989). Admiral Ins. Co. also brought out the difference between this attorney-client privilege and the work-product rule:
In ordering production of a privileged statement on the facts of plaintiffs’ assertion that they could not otherwise obtain the information contained in the statement, the district court confused the attorney-client privilege with the work-product rule. The work-product rule is not a privilege but a qualified immunity protecting from discovery documents and tangible things prepared by a party or his representative in anticipation of litigation. Fed. R. Civ. P. 26(b)(3). Although the rule affords special protections for work-product that reveals an attorney’s mental impressions and opinions, other work-product materials nonetheless may be ordered produced upon an adverse party’s demonstration of substantial need or inability to obtain the equivalent without undue hardship. See Upjohn, 449 U.S. at 401, 101 S.Ct. at 688.
Id. at 1494.
We adopt this analysis as a correct statement of the law. The work product rule would apply to documents, records, reports, exhibits, and the like which may be contained in the Report, because those documents were created “in anticipation of litigation.” Other opinions, testimony and/or statements of witnesses made to counsel in confidence, and certain memoranda would be subject to the attorney-client privilege.
We find that the issues involved in this petition meet the standards necessary to consider the merits of this petition for mandamus relief. As we discussed, we believe that Perrigo has no other adequate means to attain the relief it desires, and any error in this regard would not be correctable on appeal. Furthermore, the Michigan Supreme Court has not addressed these questions arising out of the operation of the important new statute regulating stockholder derivative suits. We have discovered little judicial precedent addressing the discovery aspects of this legislation, an area of increasing corporate and shareholder concern. Therefore, we turn to the merits of Perrigo’s petition.
We discern no appropriate mandamus relief with respect to the district court’s finding that the derivative plaintiffs are entitled to the Report based on substantial need and [438]*438undue hardship only-for purposes of responding to Perrigo’s motion to dismiss. Though we have found no cases dealing with this particular issue in Michigan, we agree that the purposes of the Michigan statute will be furthered by allowing the plaintiffs access to the Report. As a matter, of fairness and practicality, the derivative plaintiffs (unlike the class action plaintiffs) will need the Report in order to “rebut the presumption that Formanek acted in good faith and made a reasonable investigation.” Picard, 951 F.Supp. at 687. Further, there was no error in ordering disclosure of the Report to the district court under seal. Even if Perrigo were correct that the court’s only function under the Michigan statute is to determine whether Formanek’s recommendation of dismissal represents a good faith determination based upon a reasonable investigation by all disinterested independent directors of Perrigo, the court must have the Report before it can properly rule on Perrigo’s motion and perform its judicial function. We make no judgment at this juncture about the district court’s actual function under the Michigan statute.3
We are concerned, however, with this portion of the district court’s March 14, 1997, order:
Once Plaintiffs obtain the Formanek Report, they will determine whether or not the Report will be submitted to the Court with their response to either or both of Perrigo’s pending motions. However, there are still open questions of whether this ease will be resolved between the parties after Plaintiffs have seen, the Formanek Report or whether the Report will be submitted by either side. In any event, if and when the Report is submitted by either side in order to induce reliance by this Court, it will become a public record for the reasons previously stated by this Court..
(Footnote omitted). When read together with the Picard order, the effect of this mandate is apparent. Perrigo must produce the Report and waive all of its rights thereto if it chooses to maintain its motion to dismiss. In the Picard order, however, the court found specifically that Perrigo has not voluntarily waived either its attorney-client privilege or work product immunity. See Picard, 951 F.Supp. at 688-90. Also, it noted that Perrigo did not use the Report in its motion, nor did it disclose any of the contents to the Perrigo Board and counsel. Id. at 689.
This circuit, has found that a corporation’s submission of portions of a report does not waive the attorney-client privilege if the report is not released in “significant part.” See In re Grand Jury Proceedings October 12, 1995, 78 F.3d 251, 254 (6th Cir.1996) (relying on In re Dayco Corp. Derivative Securities Litigation, 99 F.R.D. 616, 619 (S.D.Ohio 1983)). In the instant case, Perrigo did not release even a small portion of the Report to support its claim 'that Formanek’s recommendation was made in good faith or that his investigation was reasonable. Although Perrigo requested that it be allowed to submit a redacted version of the Report for that purpose, the court rejected that request.4 Kearney, 949 F.Supp. at 511.
Therefore, Perrigo was faced with the choice of waiving the protection of the Report or withdrawing its motion to dismiss. Such a result certainly could not have been intended by § 450.1495, which was designed specifically to allow the disinterested independent directors to determine whether a derivative suit would be in the corporation’s best interests. The statute involved does not require that the disinterested independent director issue a report with its recommendation, nor does it require that he consult with [439]*439counsel. However, in order to perform a meaningful investigation, particularly in large corporations, consultations with counsel and exchanging of documents would be commonplace.
The dissent should recognize that a kind of automatic public disclosure of the Report upon the filing of a motion to dismiss under the Michigan statute will hinder future communications between the independent directors and attorneys reviewing whether a derivative action is in the corporation’s interest. Requiring public disclosure in this and similar derivative suits would cause future disinterested independent directors in Michigan reviewing whether a derivative litigation is in the corporate interest not to produce extensive written materials. These concerns constitute additional reasons for our conclusion that the Michigan legislature could not have intended the effect of the district court’s order. Those valid interests, which most certainly are important to Michigan lawmakers, provide a “reasoned basis” for our decision.5 Michigan would surely not wish to discourage disinterested independent directors from working candidly with counsel in discharging their duties under the statute. See Cyril Moscow et al., Michigan’s Independent Director, 46 Bus. Law 57, 59 (1990) (“[T]he statute is structured to be an effective monitor of management, particularly in the area of managerial integrity.”). A finding that would force Perrigo to waive all of its rights with respect to the privileged material would have such an effect.6
The actions of the district court, which we approve apart from ordinary public disclosure, which is the real basis of the dissent’s disagreement, do not deny any opposing party access to the Formanek Report information important to their position in this case. We do not deem, at this juncture of the proceedings, that Perrigo has utterly waived its privilege from public disclosure under Michigan law cited by the dissent, Howe v. Detroit Free Press, 440 Mich. 203, 487 N.W.2d 374 (1992). So-called “fairness” considerations simply do not require public disclosure under these circumstances, and what discovery has been directed to the other parties in no way prejudices them. We simply do not understand the dissent’s continued emphasis on keeping the privileged material (the Report) “secret from the opposing party,” “shielding prejudicial information,” and therefore “unfair” and inhibiting to the “truth-seeking process.” Nothing of the sort has occurred under the district court’s orders which we have not disturbed. See footnotes S and 6 of the dissent. We make no “presumption favoring Perrigo;” rather, we mandate a further hearing to consider all the appropriate balancing factors before ordering full public disclosure, thereby setting aside entirely the important privilege and immunity entitlement in this case.
The district court’s order also has the effect of giving the derivative plaintiffs, representing a tiny fraction of Perrigo’s shareholders, the untrammeled power to waive Pemgo’s protections in the Report if Perrigo does not first do so.7 By doing so, they [440]*440could reveal the entire Report, which may contain highly confidential information, business trade practices or secrets, or other materials helpful to competitors and prejudicial to Perrigo itself. Although the district court purports to “give[ ] Perrigo control of whether and when the Report will be submitted and become part of the public record,” Picard, 951 F.Supp. at 692, that control can be exercised only by its decision to pursue ox withdraw the motion to dismiss. If Perrigo pursues the motion, then the district court has given the derivative plaintiffs the option of submitting the Report in defense of the motion and thereby publicizing its contents. We find that such a result would be contrary to Michigan law, which holds that “it is not within the power of the court or any party to waive the privilege for [the client].” Agee v. Williams, 17 Mich.App. 417, 169 N.W.2d 676, 679 (1969) (citing Schaibly v. Vinton, 338 Mich. 191, 61 N.W.2d 122, 124 (1953)).
The entire panel agrees that the equities involved in this case weigh in favor of the district court’s decision to order disclosure of the Report to the plaintiffs and to the court. We disagree, however, with the dissent with respect to the balance of the equities and the application of the law involved in determining whether the Report should be disclosed to the public at this juncture. We believe it is important to conduct a hearing at a later time to determine the wisdom of such a course, as Plaintiffs’ counsel conceded at oral argument.
We recognize that the public has a right to copy and inspect judicial records. See Nixon v. Warner Communications, Inc., 435 U.S. 589, 597, 98 S.Ct. 1306, 1311, 55 L.Ed.2d 570 (1978); Richmond Newspapers, Inc. v. Virginia, 448 U.S. 555, 569-73, 100 S.Ct. 2814, 2823-25, 65 L.Ed.2d 973 (1980). “[That right], however, is not absolute; district courts have the discretion to deny or permit access to judicial records.” Picard, 951 F.Supp. at 691 (citing Nixon, 435 U.S. at 598, 98 S.Ct. at 1312). This Report should not become a part of the “judicial record” until the district court has read the Report and has adequately weighed- the interests of public against the interests of Perrigo in maintaining its privilege as to all or, part of the Report.8 If and when the district court intends to rely on the Report in making a decision in this case, then at that time it should conduct a hearing regarding whether the Report or parts thereof should be disclosed to the public, or whether that information should remained sealed. We look to language of a case cited by the dissent in connection with this holding:
In applying the balancing test, we counsel that a court “should begin its analysis with a presumption in favor of preserving the privilege.” Accordingly, the burden of establishing a waiver under the balancing approach rests on the party seeking discovery. Further, we emphasize that discovery, if allowed, should be narrowly limited to those portions of the privileged material that bear directly on the issues at hand. As the Court in Rdhn, supra, 98 Mich.App. at 600, 296 N.W.2d 315, aptly eautionéd, the need to pierce the veil of confidentiality “does not mean that defendants should receive wholesale access to the confidential records of others.”
Howe v. Detroit Free Press, Inc., 440 Mich. 203, 487 N.W.2d 374, 383 (1992) (emphasis added; citations omitted).
With respect to discovery of an investigative report protected by the attorney-client and work product protections, we take note that public corporations, such as Perrigo, are required by a myriad of laws and regulations to report regularly in considerable detail their financial dealings. The public, therefore, already has full access to security information, financial data, and stock information of Perrigo, as well as a wealth of information about officers and directors. We see no need at this stage, therefore, in the interest of “fairness,” to give confidential Report information to plaintiffs in a hostile securities action (a part of the public domain). The parties in this case will have full access to this Report. Certainly, there is no require[441]*441ment, as indicated by the dissent, for documents not a part of the Report itself which may have been produced in confidence to Formanek or his counsel as investigators.
We have indicated that mandamus relief is not warranted with respect to that part of the district court’s order making the Report available to the plaintiffs subject to the protective order. We have also indicated that mandamus relief is not warranted with respect to the district court’s examination, under seal, of said Report. As the district court found, Perrigo did not waive its attorney-client privilege by submitting the Report to the Court for its in camera review. Picard, 951 F.Supp. at 688 (quoting United States v. Zolin, 491 U.S. 554, 568-69, 109 S.Ct. 2619, 2628-29, 105 L.Ed.2d 469 (1989)). We are concerned, however, with that part of the March 14, 1997, order holding that the Report, if submitted by either party “to induce reliance” by the district court, automatically “beeome[s] a public record.” That condition, we believe, requires mandamus relief, because it would force Perrigo to choose between maintaining its motion to dismiss or waiving its privilege to the Report, and it would give the plaintiffs the power to waive Perrigo’s protections and reveal the entire Report to the public. We make this judgment based on the purposes behind the Michigan statute, and we are bound to determine what we believe a Michigan court would do under the same circumstances.
It may be that for good and sufficient reasons at some point in the proceedings, after a full hearing on the matter, the district court may conclude that public disclosure of the Report or certain portions thereof is necessary and appropriate for limited purposes. We deem it clear error, however, to direct that simply by “submitting” the Formanek Report, in purported compliance with the Michigan statute, to “induce reliance” by the court (which will undoubtedly occur), automatically places it in the public domain. “To hold otherwise may have the effect of thwarting the developing procedure of corporations to employ independent outside counsel to investigate and advise them in order to protect stockholders, potential stockholders and customers.” Diversified Indus., Inc. v. Meredith, 572 F.2d 596, 611 (8th Cir.1978) (en banc).9 The district court itself may study, examine, interpret, and inspect tbe Report without making it public property in connection with the disposition of the motion to dismiss.
We GRANT mandamus relief, then, only in the narrow respect indicated. We SET ASIDE that portion of the district court’s order which reads: “In any event, if and when the Report is submitted by either side in order to induce reliance by this Court it will become a public record for the reasons previously stated by this Court.” The case is REMANDED to the district court with instructions to VACATE the designated sentence and its effect from the March 14, 1997 order.
