19.1 Privilege in law enforcement investigations

19.1.1 Attorney–client privilege

The attorney–client privilege is recognised in the United States as ‘the oldest of the privileges for confidential communications known to the common law’.[2] It is viewed as serving a crucial function in ‘encourag[ing] full and frank communication between attorneys and their clients’ and thereby promoting ‘the observance of law and administration of justice’.[3] It protects information shared between a lawyer and the client, where the information is (1) a communication, (2) made in confidence, (3) between a person who is, or is about to become, a client (4) and a lawyer (5) for the purpose of obtaining legal advice or assistance.[4]

Attorney–client privileged communications may take many forms, from oral communications, to emails, to text messages, so long as each communication is undertaken in confidence for the purpose of seeking or rendering legal advice.[5] Once the privilege is created, the privilege continues, and may be invoked at any time (unless it has been waived or is otherwise subject to an exception), even following the termination of the attorney–client relationship or the death of the client.[6]

In Upjohn Co. v. United States,[7] the US Supreme Court held that a company’s attorney–client privilege extends to company counsel’s communications with employees in certain prescribed circumstances.[8] Rather than providing a simple objective test, the Upjohn court instead established five factors to guide courts in determining whether the company’s privilege should extend to counsel’s communications with its employees:

  • whether the communications were made by employees at the direction of superior officers of the company for the purpose of obtaining legal advice;
  • whether the communications contained information necessary for counsel to render legal advice, which was not otherwise available from ‘control group’ management;
  • whether the matters communicated were within the scope of the ­employee’s corporate duties;
  • whether the employee knew that the communications were for the purpose of the company obtaining legal advice; and
  • whether the communications were ordered to be kept confidential by the employee’s superiors, including that the communications were considered confidential at the time and kept confidential subsequent to the communication.[9]

When these elements are established, courts generally consider communications between company counsel and an employee to be within the scope of the company’s attorney–client privilege.[10]

While the privilege provides broad protection for confidential communications among those within the attorney–client relationship, disclosing the contents of these communications to a third party outside the scope of the protection (such as a government agency) may result in a waiver of the applicable privilege.

19.1.2 Attorney work-product

In the United States, the doctrine of attorney work-product also protects from disclosure certain documents and other materials prepared in anticipation of litigation or for trial. Although such work-product is most commonly prepared by an attorney, work-product protection may extend to materials prepared in anticipation of litigation by third parties at the attorney’s direction, including materials prepared by the client.[11] But while the work-product doctrine offers certain protections for an attorney’s impressions, opinions and legal conclusions, such documents are not considered ‘privileged’ like attorney–client communications, but instead are afforded a qualified protection from discovery.[12]

In the seminal case of Hickman v. Taylor,[13] the Supreme Court formally recognised the attorney work-product doctrine, establishing the scope of the protection to include materials prepared in anticipation of litigation.[14] The Hickman court also qualified this work-product protection by finding that, upon a showing of good cause, an adversary could obtain discovery of documents containing ‘factual work product’.[15] The Court recognised that substantially greater – if not absolute – work-product protection should be given to documents that reflect the attorney’s legal theories, strategy, assessments and mental impressions (opinion work-product).[16]

In United States v. Nobles,[17] the Supreme Court extended the work-product doctrine beyond the scope of materials created by counsel, recognising that attorneys often rely on the assistance of investigators and other agents in preparation for trial. The Court found that it is ‘necessary that the [attorney work-product] doctrine protect material prepared by agents for the attorney as well as those prepared by the attorney himself’.[18] Following the Supreme Court’s guidance in Nobles, work-product protection is understood to be extended to material prepared ‘by or for [a] party’s representative’ as long as the agent is assisting in preparing for litigation and working at the direction of the attorney.[19]

The modern federal work-product doctrine is codified in Rule 26(b)(3) of the Federal Rules of Civil Procedure (the Federal Rules) and stands in line with the Supreme Court’s guidance in Hickman and Nobles. In particular, Rule 26(b)(3) eliminates the distinction between attorney work-product and non-attorney work-product, focusing on whether the materials were prepared in anticipation of litigation or trial.[20] Further, it preserves work-product protections unless the party seeking discovery has a ‘substantial need’ for the materials in the preparation of the party’s case and the party is unable without ‘undue hardship’ to obtain the ‘substantial equivalent’ of the materials by other means.[21]

While the attorney work-product doctrine offers a qualified protection for documents created in anticipation of litigation, disclosing the contents of such documents to a third party outside of the attorney–client relationship (such as a government agency) may result in a waiver of this protection.[22]In addition, courts will examine the temporal proximity of the investigation to the threatened litigation in determining whether the work-product doctrine applies.[23]

19.1.3 Common interest or joint defence privilege

The joint defence (or ‘common interest’) privilege is a doctrine that preserves the attorney–client privilege and work-product doctrine, despite disclosure of otherwise protected information to third parties.[24] As explained by the Second Circuit Court of Appeals, the privilege ‘serves to protect the confidentiality of communications passing from one party to the attorney for another party where a joint defence effort or strategy has been decided upon and undertaken by the parties and their respective counsel’.[25] In general, a party asserting the privilege must demonstrate that (1) the communications were made in the course of a joint defence effort, (2) the statements were designed to further the effort and (3) the privilege has not otherwise been waived.[26] If the privilege is challenged, the burden is on the defendants to demonstrate the existence of a joint defence arrangement.[27]

While a joint defence arrangement has not been held to create a direct attorney–client relationship between counsel for one party and another, some courts have found that the sharing of confidential information creates an implied attorney–client relationship among the parties to the joint defence. In United States v. Henke,[28] for example, the Ninth Circuit held that the joint defence privilege can, in certain circumstances, create an implied attorney–client relationship, as well as a disqualifying conflict of interest. In that case, three executives – Gupta, Desaigoudar and Henke – were charged with conspiracy, making false statements, securities fraud and insider trading.[29] All three defendants participated in joint defence meetings where they shared confidential information.[30] On the eve of trial, however, Gupta entered into a cooperation agreement and agreed to testify for the government.[31] Gupta’s lawyers threatened Desaigoudar and Henke’s attorneys with legal action if they revealed any confidential information obtained as part of the joint defence meetings. Desaigoudar and Henke’s attorneys eventually moved to withdraw because they believed their duty of confidentiality to Gupta prevented them from effectively cross-examining him.[32] The Ninth Circuit held that the lower court erred in denying the motions to withdraw, as the joint defence privilege created ‘a disqualifying conflict where information gained in confidence by an attorney [became] an issue’.[33]

To mitigate the risk that information shared in the context of a joint defence agreement may lead to later disqualification, many lawyers choose to include written disclaimers in their joint defence agreements along the following lines:

Nothing contained [in this agreement] shall be deemed to create an attorney–client relationship between any attorney and anyone other than the client of that attorney . . . and no attorney who has entered into this Agreement shall be disqualified from examining or cross-examining any joint defense participant who testifies at any proceeding, whether under a grant of immunity or otherwise, because of such an attorney’s participation in this agreement, and it is herein represented that each party to this agreement has specifically advised his or her client of this clause.[34]

Courts have found such provisions to permit an attorney to cross-examine a witness who was a former member of a joint defence arrangement and has since become a government cooperator, and have even permitted counsel to impeach the witness using statements that would otherwise be protected as privileged under the joint defence.[35]

The case of SEC v. Rashid[36] demonstrates the importance of both confirming and recording the intention to enter into a common interest relationship. In Rashid, the SEC was investigating the defendant’s use of corporate expenses while employed at Apollo Management LP. During the investigation, the defendant retained counsel separate from that of the company, and eventually hired a separate firm to replace the first. During a later deposition of a representative from his prior law firm, the SEC sought to enquire about discussions with company counsel. When the defendant claimed such communications were protected by common interest privilege, the SEC moved to compel the testimony, arguing that the common interest privilege is narrowly construed and that the defendant did not meet his burden of showing that such a relationship existed.

The court ordered the deposition to proceed, finding insufficient evidence of a common interest relationship. In so ruling, it considered, among other things: (1) the lack of a written common interest agreement; (2) testimony from company counsel that they did not recall entering into a common interest relationship; (3) the defendants’ lack of ability to recall specific details of the terms of the alleged agreement; and (4) that company counsel had delivered the Upjohn warnings at their first meeting with the defendant. The court determined that the common interest privilege cannot apply in a circumstance where there is no evidence that both parties agreed to pursue a joint legal strategy.

Further, to preserve the attorney–client privilege in the context of a joint defence arrangement, confidentiality must still be maintained against those outside the arrangement, because disclosure to a single outsider could constitute waiver of the information discussed in the outsider’s presence.

19.2 Identifying the client

The ‘client’ in an attorney–client relationship is generally defined as the intended and immediate beneficiary of the lawyer’s services, who communicates with the attorney to obtain legal advice, and interacts with the attorney to advance his or her own interests.[37] Defining the ‘client’ becomes more difficult in the context of corporate representation, as a company typically speaks by and through its employees, but the corporation’s counsel represents not those individual agents, but rather the corporation itself.[38] As a general matter, a corporation’s attorney–­client privilege is controlled by the management of the organisation.[39] An employee or officer cannot assert the corporation’s privilege if the corporation waives it,[40] and an employee cannot waive the corporation’s privilege if the corporation asserts it.[41]

In cases where the interests of an employee are or may become adverse to that of the company during a government investigation, the Rules of Professional Conduct[42] dictate that attorneys explain clearly whom they represent.[43] Interviewing employees in the context of a government investigation inevitably creates situations in which conflict between company and employee may arise. In particular, individuals should be advised to obtain separate counsel in situations where they are (1) the target of the investigation, (2) a probable whistleblower or (3) an employee facing risk of criminal liability. In any of these circumstances, the implicated employee should not be involved in the day-to-day supervision of company counsel’s own investigation, including serving in the reporting chain.

Company counsel may encounter circumstances where an employee seeks to assert the attorney–client privilege to prevent the disclosure of information uncovered by counsel during investigative interviews by arguing that company counsel represents the employee as an individual. The Third Circuit, in In re Bevill Bresler & Schulman Asset Management Corp, developed a five-part test (the Bevill test) to examine the merits of such an assertion by an individual employee against company counsel.[44] Under this test, employees must show that:

  • they approached corporate counsel for the purpose of seeking legal advice;
  • they made it clear that they were seeking advice in their individual capacity;
  • counsel sought to communicate with the employee in this individual capacity, mindful of the conflicts with its representation of the company;
  • the communications were confidential; and
  • the communications did not concern the employee’s official duties or the general affairs of the company.[45]

The Bevill test has been recognised by other jurisdictions as a means of assessing whether a company employee may assert the attorney–client privilege in an individual capacity arising out of communications with corporate counsel.[46]

In United States v. Blumberg,[47] for example, the District of New Jersey applied the Bevill test where an individual employee sought to claim personal privilege protection for communications with the company’s lawyer. In assessing the fifth factor of the test, the court considered the individual employee’s claim that he had discussed with company counsel his ‘potential for criminal exposure’ and the fact that he was just a ‘fact witness’.[48] The court ultimately concluded that this exchange did not create an individual attorney–client relationship, and that the company still owned the privilege covering the employee’s communications, and thus could waive it (presumably over his objection).[49]

In United States v. Holmes,[50] the Northern District of California applied the Ninth Circuit’s Graf test[51] to former Theranos chief executive officer Elizabeth Holmes’s claim that her communications with company counsel were privileged, arguing that the firm represented both Theranos and Holmes individually. The court found that Holmes’s claim of privilege failed under the second, fourth and fifth prongs of Graf because there was no documentation to support the position that Holmes sought legal advice from counsel in her personal capacity (including engagement letters or evidence of fees paid) and her subjective belief was insufficient; there were no discussions between Holmes and counsel individually, but instead always in the presence of a third party; and all conversations with counsel related to Holmes’s official duties and the general affairs of the company, rather than her individual interests. The court therefore held that company counsel did not represent Holmes in her individual capacity, and therefore she was not entitled to shield the communications from disclosure.

To mitigate the risks created by potentially divergent interests between the company and individual employees, counsel should be clear in their engagement letter about not only whom they represent but also whom they do not. Further, mindful of the considerations outlined by the Bevill court, company counsel should take care during interviews with individual employees to limit their discussions to matters within the scope of the employee’s official duties, rather than matters that may implicate the employee’s personal interests. Finally, in the event that discussions with an individual employee diverge to matters implicating legal advice in the employee’s individual capacity, counsel should reiterate to the employee that they have been retained to represent the company and the company’s interests, and potentially advise the employee to retain separate counsel with respect to these other matters.

19.3 Maintaining privilege

19.3.1 Employee interviews

It is generally best if counsel conducts the employee interviews in the context of a government investigation, to ensure that what is said during the interview is covered by the attorney–client privilege, and that notes or memoranda documenting the interview are similarly privileged.[52] Recordings of interviews may, however, be considered purely factual communications that – as verbatim transcriptions – may not be subject to the attorney work-product doctrine.[53] Accordingly, it is general practice to have the attorney interviewer (or, more likely, another attorney in the room) take written notes of the interviews that include his or her thoughts and mental impressions. And because opinion work-product receives greater protection than fact work-product, it is more likely that written notes including an attorney’s thoughts and impressions will be protected.[54]

While it is often most advantageous to have counsel conduct the witness interviews in an investigation, a court may still find that interviews conducted by non-lawyers maintain attorney–client privilege if they are acting as agents for lawyers. For example, in In re Kellogg Brown & Root Inc (KBR),[55] the DC Circuit court held that the work of an engineering and construction firm involved in an the internal investigation was afforded work-product protection where the investigation was conducted ‘under the auspices of KBR’s in-house legal department, acting in its legal capacity’.[56] The court held that ‘[s]o long as obtaining or providing legal advice was one of the significant purposes of the internal investigation, the attorney–client privilege applies’.[57] The court’s decision in KBR underscores the importance of making it clear that witness interviews conducted in the context of an internal investigation are for the purpose of rendering legal advice.[58]

Consistent with these principles, at the outset of any employee interview, counsel should give the employee an Upjohn warning, which makes clear that the communications between company counsel and the employees are confidential and protected under attorney–client privilege, and specifies that the privilege belongs to the company and that the company may choose to waive that privilege in the future. If clearly given, an Upjohn warning sets the boundaries of the interview and removes any doubt about whether counsel represents the employee.

In KBR, the DC Circuit noted that there are no ‘magic words’ that must be used to deliver a proper Upjohn warning.[59] Nevertheless, in practice, Upjohn warnings typically include some variation of the following components:

  • The lawyer represents the company only and not the witness personally.
  • The lawyer is collecting facts for the purpose of providing legal advice to the company.
  • The communication is protected by attorney–client privilege, which belongs exclusively to the company, not the witness.
  • The company may choose to waive the privilege and disclose the communication to a third party, including the government.
  • The communication must be kept confidential, meaning that it cannot be disclosed to any third party other than the witness’s counsel.[60]

Once the Upjohn warning is given, and before any substantive interview commences, counsel should confirm that the witness understands the warning, answer any questions the witness has about it and establish that the witness is agreeable to being interviewed under these terms. As an additional precaution, counsel should remind the witness at the conclusion of the interview not to discuss the substance of the interview with anyone else, except to the extent that the witness wishes to convey additional information or to ask follow-up questions of counsel.

Once a witness interview is complete, recording the content of the interview is essential to the investigation. The summary should state expressly that it does not constitute a verbatim transcription of the interview and that the summary contains the thoughts, mental impressions and legal conclusions of counsel. The summary should also confirm the delivery of the Upjohn warning, indicating the employee’s understanding of the warning and willingness to proceed with the interview.

The importance of recording the provision of the Upjohn warning is underscored by the case of United States v. Ruehle.[61] In Ruehle, outside counsel conducted an interview of an employee, William J Ruehle, during an internal investigation. During the interview, Ruehle made statements that he later sought to suppress from his criminal trial. He argued that the statements were privileged because outside counsel had previously represented him in his individual capacity in a shareholder lawsuit, and counsel had not otherwise advised him that his statements during the internal investigation could be disclosed to third parties. The court found there to be inadequate evidence that Ruehle had been given Upjohn warnings, finding it persuasive that there was no reference to the delivery of Upjohn warnings in counsel’s interview memoranda.

While the court’s decision was later reversed on other grounds, Ruehle illustrates the importance of maintaining a record of the delivery of Upjohn warnings. The absence of an Upjohn warning is not dispositive, however, as courts will also consider whether the employee and attorney ‘explicitly or by their conduct manifest[ed] an intention to create an attorney/client relationship’.[62] Without an Upjohn warning, courts will assess whether the attorney had ‘reason to suspect that the firm’s interests and the [employee’s] interests diverged’ during the period in question and also whether the employee’s ‘assumption’ that the company attorney was his personal attorney was ‘reasonable’ for someone of his knowledge and experience.[63]

Issues may also arise when interviewing employees in the context of an internal investigation, to the extent that the investigation is prompted by a government inquiry when there is extensive coordination with a government regulator. In United States v. Connolly,[64] a bank engaged outside counsel to conduct an investigation into the bank’s LIBOR practices that was prompted by a letter from the Commodity Futures Trading Commission (CFTC) requesting that the bank ‘cooperate fully’ by ‘voluntarily engaging’ outside counsel to conduct a review. During the investigation, outside counsel ‘coordinated extensively’ with both the CFTC and the Department of Justice (DOJ), and the government agencies gave substantial direction to the lawyers as to which employees should be interviewed and how to approach the interviews. After a bank employee, Connolly, was later indicted and convicted for conspiracy and wire fraud for his conduct in connection with the manipulation of LIBOR, he moved to vacate his conviction on the theory that his prosecution was predicated on, and fatally tainted by, statements that he gave in interviews conducted by outside counsel during the investigation. He argued that counsel was effectively deputised by the government in conducting the interviews, and as a result his statements should be deemed involuntary and rendered inadmissible under Garrity v. State of New Jersey,[65] since he made the statements under the threat of termination of employment in violation of his Fifth Amendment rights. Chief Judge Colleen McMahon of the Southern District of New York found that outside counsel here was ‘de facto that Government for Garrity purposes’ and noted that she was ‘deeply troubled by this issue’, which had ‘profound implications’ for how government investigations are conducted. And while the Court ultimately declined to overturn the employee’s conviction, holding that the government did not ‘use’ his compelled statements in indicting or prosecuting him, the Court’s comments and admonition will continue to have a significant impact on the level of coordination with government agencies in investigations going forward.

19.3.2 Former employees

Interviews with former corporate employees about matters within the scope of their prior employment may also be protected by the attorney–client privilege.[66] While some courts have held that the distinction between a present and a former employee ‘is irrelevant for purposes of the attorney-client privilege’, other courts decline to extend the privilege because former employees ‘are not the client’, ‘share no identity of interest in the outcome of the litigation’, ‘have no duty to their former employer to provide such information’, and are indistinguishable ‘from any other third party who might have pertinent information’ about the parties to the lawsuit.[67]

But even though courts of different jurisdictions are split as to whether the attorney–client privilege should extend to discussions with former employees as a general matter,[68] most courts agree that narrowly tailored discussions with a former employee related exclusively to the period of their former employment should remain privileged.[69] Consequently, counsel conducting an investigation should carefully focus the interview with a former employee on matters that occurred during the former employee’s tenure, as some district courts have held that interviews with a former employee on subjects that occurred after the employment had ended are not privileged.[70]

And regardless of whether the privilege is likely to be maintained, counsel should also determine whether the employee is likely to be cooperative or to maintain the confidentiality of the interview, including considering (1) the circumstances of the employee’s departure and (2) whether the employee will be contractually obliged to maintain the confidentiality of the interview, through a severance agreement, for example.

19.3.3 Non-legal advice

At the outset of an internal investigation, the corporation should document that the investigation is being conducted for the purpose of obtaining legal advice and at the direction of counsel. If such intention is not documented, and it appears instead that employee interviews are being conducted in the context of a non-legal investigation, such communications may not be effectively cloaked in the attorney–­client privilege. In Koumoulis v. Independent Financial Marketing Group Inc,[71] for example, the plaintiffs were former and current employees of a company in the business of providing investment products to financial institutions.[72] The Eastern District of New York found that reports documenting internal discrimination complaints and the subsequent investigation by the company’s human resources managers were not protected as attorney–client privileged because ‘their predominant purpose was to provide human resources and thus business advice, not legal advice’.[73]

In light of Koumoulis, counsel must be ever mindful of stating explicitly at the outset of an investigation that its communications are outside the course of the day-to-day operation of the client’s business and are explicitly aimed at assisting the delivery of legal advice. To the extent that litigation is reasonably foreseeable, it should be noted in all memoranda generated in the context of the investigation. Further, counsel should confirm with individual employees that when they are seeking legal advice – rather than business advice – the employees should be similarly explicit in their communications, labelling them as ‘attorney–client privileged’. More important than any label or transcription, however, is that the context of such documents must reflect the solicitation and receipt of legal, rather than business, advice.[74]

19.3.4 Business advice in attorney communications

Particularly among in-house counsel, there are often circumstances where an attorney provides business advice, rather than purely legal advice.[75] In the case of In re Grand Jury, the Ninth Circuit Court of Appeals recognised that in the ‘increasingly complex regulatory landscape, attorneys often wear dual hats, serving as both a lawyer and a trusted business advisor’.[76] To account for this, the court adopted the ‘primary purpose’ test for dual-purpose attorney communications, focusing on whether the primary purpose of the communication is to give or receive legal advice, as opposed to business advice.[77] Attorneys can signal that their communications are ‘primarily’ intended to convey legal advice by, among other things: (1) appropriately labelling legal advice within written communications with ‘privileged’ headings or legends; (2) encouraging business counterparts to make their requests for legal advice explicit within the business communications; and (3) instructing business counterparts to restrict communications conveying legal advice to those who need to know.

Merely copying a lawyer on dual-purpose communications is insufficient to protect the communication as privileged. In City of Roseville Employees’ Retirement System v. Apple Inc,[78] for example, the Northern District of California ordered Apple to produce internal communications with counsel related to an investor disclosure, reasoning that email exchanges in which in-house counsel were merely copied – without providing legal advice – may not be withheld as privileged.[79] The court determined that many of the emails were clearly exchanged for a business purpose, rather than a legal one, including emails that addressed the issuer’s financial performance.[80] By contrast, it upheld the company’s assertion of privilege over communications where counsel explicitly provided legal advice, including substantive advice on internal drafts of its investor disclosure.[81]

Lawyers not working in a law firm should take special care to ensure that their communications with clients containing legal advice remain privileged. In the context of email communications, for example, legal advice will only be protected as privileged to the extent ‘the intent to communicate in confidence is objectively reasonable’.[82] For attorneys using their company email for client communications, for example, the objective reasonableness of this intent may hinge on the company’s email policies.[83]

In Eastman v. Select Committee to Investigate the January 6 Attack on the US Capitol, the court examined communications between former President Donald J Trump and his election lawyer, who used an email account that was administered by Chapman University’s Fowler School of Law for his client communications.[84] It determined that the communications were not protected by the attorney–client privilege because the law school had a policy that permitted it to monitor employee emails and respond to lawful subpoenas, and therefore any expectation of confidentiality over those email communications was not reasonable.[85]

19.4 Exceptions to attorney–client privilege protection

Even if all the prerequisites for establishing attorney–client privilege are met, there are circumstances when otherwise protected communications between a lawyer and a client may become discoverable by government agencies or private litigants. First, whenever a client discloses confidential communications to third parties, including government agencies, the disclosure may constitute a waiver of the privilege as to both the communication that has been disclosed and other communications relating to the same subject matter Second, the crime-fraud exception permits disclosure if the attorney–client communications at issue were in furtherance of the crime or fraud intended by the client.

19.5 Waiving privilege

There are several circumstances where the attorney–client privilege can be intentionally or inadvertently waived, particularly in the context of government investigations. Federal Rule of Evidence 502(a) governs disclosures made to a federal officer or agency and also the scope of waiver in such disclosures.[86] It explicitly states that disclosure of attorney–client or work-product protection to the federal government creates a waiver that extends to other undisclosed communication or information in a federal or state proceeding if (1) the waiver is intentional, (2) the disclosed and undisclosed communications or information concern the same subject matter and (3) they ought in fairness to be considered together.[87]

While the ‘fairness’ requirement of Rule 502(a) creates some uncertainty as to when subject-matter waiver might occur, in practice, courts typically look to the reason for the initial disclosure when determining the scope of a waiver. If a court determines that a party selectively disclosed privileged information to gain a strategic advantage to the government’s detriment, it is more likely to find a full subject-matter waiver.[88] But, if the disclosure occurred outside the context of litigation, or if the disclosure was not intended for – or did not actually result in – a strategic advantage to the disclosing party, the court is likely to find a limited waiver.[89]

In the case of United States v. Treacy,[90] for example, Judge Rakoff of the Southern District of New York quashed a defendant’s subpoena for a law firm’s interview memoranda that had not previously been provided to the government, rejecting the theory that furnishing some interview memoranda to the government waived privilege with regard to others covering the same subject matter.[91] The Court relied on the advisory committee notes in Rule 502(a) in support of its ‘fairness’ assessment, finding that subject-matter waiver should be reserved for the narrow circumstances where a party seeks to disadvantage their adversary through a selective or misleading disclosure.[92] Further, if a party chooses to disclose attorney work-product to the government – in the form of White Papers, presentations or other memoranda – with the purpose of dissuading the government from bringing suit, one court has held that such a disclosure will waive any privilege with respect to those materials, which may subsequently be discoverable by third parties.[93]

19.5.1 Cooperation credit and waiver

Corporations subject to criminal or regulatory investigations have long faced the question of whether and when to turn over privileged material to the government. Waiving privilege has historically resulted in increased cooperation ‘credit’ from the DOJ[94] and the Securities and Exchange Commission (SEC).[95] However, changes to DOJ guidelines now forbid the government from requesting that companies waive the attorney–client privilege and preclude consideration of whether the corporation waived privilege in assessing cooperation credit.

Indeed, in response to pressure from the private sector and the legislative and judicial branches, on 12 December 2006, then Deputy Attorney General Paul J McNulty issued a memorandum containing new corporate charging guidelines for federal prosecutors through a revision to the Principles of Federal Prosecution of Business Organizations.[96] The McNulty Memorandum required that, before requesting a waiver of attorney–client or work-product privileged information from a corporation under investigation, prosecutors must establish a ‘legitimate need’ for privileged communications and seek approval of the US Attorney, who must obtain written approval of the Deputy Attorney General.[97]

In 2008, the DOJ replaced these guidelines in a memorandum authored by then Deputy Attorney General Mark R Filip.[98] The Filip Memorandum further adjusted what factors the government should consider in determining whether a corporation deserves cooperation credit: where cooperation credit had previously turned on factors including waiver of attorney–client privilege or work-product protections, it will now focus on disclosure of relevant facts.[99] In other words, a company could receive the same cooperation credit if it disclosed facts contained in non-privileged materials as it would if it disclosed facts contained in privileged materials, so long as the company discloses all relevant facts known to it.

In September 2015, the DOJ issued a memorandum authored by then Deputy Attorney General Sally Quillian Yates entitled ‘Individual Accountability for Corporate Wrongdoing’.[100] The Yates Memorandum set forth policies intended to guide the DOJ in holding individual defendants civilly and criminally liable for corporate misconduct.[101] Significantly, it requires a company to disclose ‘all relevant facts relating to the individuals responsible for the misconduct’ for the company ‘to be eligible for any cooperation credit’.[102]

While Yates has publicly remarked that these new policies are not intended to undermine the Filip Memorandum’s guidance regarding the waiver of the attorney–client privilege,[103] the mandate to disclose ‘all relevant facts’ creates some uncertainty as to whether, at least practically speaking, such a waiver may now be required once again. In describing the impact of the Yates Memorandum on companies seeking cooperation credit, Yates explained the DOJ’s view that ‘facts are not [privileged]’, and therefore a company must ‘produce all relevant facts – including the facts learned through . . . interviews [with company employees] – unless identical information has already been provided’.[104]

In November 2017, the DOJ adopted the Foreign Corrupt Practices Act (FCPA) Corporate Enforcement Policy, which provided guidance regarding the credit that the DOJ might provide to companies who self-report FCPA violations. The FCPA authorises certain benefits – including a presumption that self-reporting companies will not be criminally charged – for companies that meet the DOJ’s rigorous requirements of disclosure, cooperation and remediation, including disgorgement of ill-gotten gains.[105] In March 2018, the DOJ announced an expansion of the FCPA Corporate Enforcement Policy, noting that it may be employed as non-binding guidance in criminal cases beyond those arising under the FCPA. This announcement underscores the DOJ’s encouragement of self-reporting and cooperation by companies in a wide range of criminal cases.

On 29 November 2018, Deputy Attorney General Rod J Rosenstein delivered remarks at the American Conference Institute’s 35th International Conference on the Foreign Corrupt Practices Act[106] that reaffirmed the central tenets of the Yates Memorandum and announced a revised policy that provides federal prosecutors with greater discretion concerning whether to pursue individuals, based on varying standards between civil and criminal investigations. In particular, Rosenstein stated that companies are no longer expected to ‘admit the civil liability of every individual employee’ to qualify for cooperation credit; instead, companies should focus on identifying individuals who were ‘substantially involved in or responsible for the misconduct’, including members of senior management or the board of directors. While Rosenstein’s comments have been considered as a reversion to pre-Yates priorities, where the ‘primary goal’ in civil cases is to recover money, recent court decisions have demonstrated a continued focus on the concepts of individual accountability articulated by Yates.[107]

On 28 October 2021, Deputy Attorney General Lisa Monaco delivered the keynote address at the ABA’s 36th National Institute on White Collar Crime and announced, among other things, three actions that the DOJ plans to take with regard to its enforcement priorities. First, Monaco signalled that the DOJ is reverting to the cooperation requirements as outlined in the Yates Memorandum in 2015. In particular, Monaco reiterated the prior guidance (later loosened under the Trump administration) that to receive cooperation credit, organisations must provide to the DOJ ‘all non-privileged information about individuals involved in or responsible for the misconduct at issue’. Second, Monaco announced that when evaluating a corporation’s history of prior misconduct, ‘all prior misconduct needs to be evaluated . . . , whether or not that misconduct is similar to the conduct at issue in a particular investigation’. Third, Monaco discussed the DOJ’s imposition of corporate compliance monitors, emphasising that monitorships are not ‘disfavored’ or the ‘exception to the rule’ but rather an important tool to ‘encourage and verify compliance’. Monaco stated that the DOJ will eliminate any perception of favouritism in the monitorship programme by studying how corporate monitors are chosen and how the processes can be standardised across divisions and offices.

On 15 September 2022, Monaco clarified her prior comments regarding the DOJ’s priorities in corporate criminal enforcement.[108] First, Monaco announced several new policies reflecting the DOJ’s priority in prosecuting individuals who commit corporate misconduct, including the importance of companies coming forward quickly with evidence of individual culpability, warning that delays in reporting will result in the reduction, or even denial, of cooperation credit. Additionally, to receive maximum cooperation credit, Monaco emphasised that organisations must employ clawback provisions or other mechanisms aimed at holding those contributing to the misconduct accountable. Second, Monaco provided clarification about how a company’s full history of prior criminal, civil and regulatory prior misconduct will be taken into account. Specifically, some instances of prior misconduct will be given greater weight, recidivism will be judged in comparison to other organisations in the same industry, and compliance history of acquired companies will be discounted. Third, Monaco confirmed that the DOJ will now consider whether to require an independent compliance monitor on a case-by-case basis.

Early in 2023, the DOJ issued a revised Corporate Enforcement and Voluntary Self-Disclosure Policy (CEP), formerly known as the FCPA Corporate Enforcement Policy, which applies to FCPA cases nationwide and all other corporate criminal matters handled by the Criminal Division.[109] The 2023 CEP allows for the possibility of a company to receive credit in two situations. First, credit is possible for voluntary self-disclosures where declination is not granted. Second, even where a company does not voluntarily self-disclose, a company can receive credit if it provides extraordinary cooperation. Although ‘extraordinary cooperation’ is not well defined, then Assistant Attorney General Kenneth A Polite stated that ‘we know “extraordinary cooperation” when we see it, and the differences between “full” and “extraordinary” cooperation are perhaps more in degree than kind’, and to receive credit for extraordinary’ cooperation, ‘companies must go above and beyond the criteria for full cooperation’.[110]

In light of this guidance, corporate counsel must be mindful about entering into joint defence agreements that might limit their ability to share with the government the underlying facts learned during the investigation, especially if the company is facing exposure to a potentially devastating criminal charge if it does not receive credit for cooperating with the government. In addition, the Yates Memorandum underscores the importance of issuing comprehensive Upjohn warnings when interviewing company employees, as a mandate to disclose ‘all relevant facts’ may involve the revelation to the government of facts disclosed by (potentially culpable) employees in the context of investigative interviews.

19.5.2 Inadvertent disclosure of privileged material

Particularly in cases where large numbers of documents are produced, it is not uncommon that a party might inadvertently disclose privileged communications. Federal Rule of Evidence 502(b) governs the court’s treatment of attorney–­client privileged and work-product material that has been inadvertently disclosed. It provides that, when making a disclosure in a federal proceeding or to a federal office or agency, the disclosure does not operate as a waiver in a federal or state proceeding if ‘(1) the disclosure is inadvertent; (2) the holder of the privilege or protection took reasonable steps to prevent disclosure; and (3) the holder promptly took reasonable steps to rectify the error’.[111]

According to Rule 502(b)’s advisory committee explanatory notes, courts are to consider several factors in determining whether the privilege holder took steps to promptly rectify the error, including:

  • the reasonableness of precautions taken;
  • the time taken to rectify the error;
  • the scope of discovery;
  • the number of documents reviewed and the time constraints for production;
  • the extent of disclosure; and
  • ‘the overriding issue of fairness’.[112]

The explanatory notes also suggest that a party can help demonstrate that its steps were reasonable by employing ‘advanced analytical software applications and linguistic tools’ in screening for privilege.[113]

Federal Rule of Civil Procedure 26(b)(5)(B) provides additional guidance on how clawback provisions may intersect with a claim of inadvertent disclosure: if information produced in discovery is subject to a claim of privilege or of protection as trial-preparation material, ‘the party making the claim may notify any party that received the information of the claim and the basis for it’.[114] After being notified, a party:

must promptly return, sequester, or destroy the specified information and any copies it has; must not use or disclose the information until the claim is resolved; must take reasonable steps to retrieve the information if the party disclosed it before being notified; and may promptly present the information to the court under seal for a determination of the claim.[115]

While the same clawback procedure is not explicitly contemplated in the criminal context, parties making disclosures in federal proceedings or to a federal office or agency may choose to enter into a voluntary clawback arrangement under Rule 502(e), including an explicit agreement that inadvertent disclosure will not constitute a waiver.[116] Such agreements are generally binding only on the parties to the agreement.[117]

A carefully drawn clawback agreement can be to the benefit of everyone in the context of a government investigation: the agency will benefit from receiving discovery more expeditiously, and the producing party will benefit from minimising the risk and added review costs in the absence of such an agreement.[118] Even where counsel takes reasonable steps to prevent the disclosure of privileged material, the complexity of government investigations creates a real risk that such materials may still be inadvertently produced. To further mitigate this risk, document production letters should include unequivocal language, preserving the client’s ability to claw back and recover inadvertently disclosed documents.

19.6 Selective waiver

The attempt to disclose privileged material to the government in the context of an investigation, while still claiming privilege and confidentiality over that same material as to other third parties, is called ‘selective waiver’. Generally, courts have refused to sanction selective waiver, finding that the disclosure of privileged material to the government destroys the confidentiality necessary to maintain a claim of privilege in the first place, and therefore waives the privilege with respect to other third parties as well.[119]

The leading case applying the selective-waiver analysis is Diversified Industries Inc v. Meredith.[120] In Diversified Industries, a corporation retained outside counsel to conduct an internal investigation into allegations of bribery.[121] The internal report prepared by outside counsel was then produced to the SEC.[122] The Eighth Circuit held that this disclosure constituted only a ‘limited waiver’ that did not preclude the corporation from subsequently withholding the report from private litigants on the grounds of the attorney–client privilege.[123] The court reasoned that a contrary ruling may undermine corporate incentives to initiate internal investigations conducted by counsel.[124]

But while Diversified Industries is still good law, the concept of selective waiver is disfavoured by most federal circuit courts,[125] which routinely hold that selective disclosure of a document to the government constitutes complete waiver of the privilege. As the DC Circuit reasoned, the privilege was not designed to allow a client ‘to pick and choose among his opponents, waiving the privilege for some and resurrecting the claim of confidentiality to obstruct others’.[126]

The Second Circuit confronted the issue of selective waiver in In re Steinhardt Partners LP.[127] While expressing reluctance to embrace selective waiver, the Steinhardt decision refused to foreclose the possibility that selective waiver may be found in some cases, at least where the disclosing party and the government share a common interest or the disclosing party has entered into an explicit agreement with the government to maintain the confidentiality of the disclosed materials.[128] As a result, in the Second Circuit, a case-by-case analysis of the facts is necessary to determine whether selective waiver may apply.[129]

The case of SEC v. Herrera[130] illustrates the risks of selective waiver inherent in making a proffer to the government. In Herrera, outside counsel conducted an internal investigation into certain apparent accounting errors in the ­company’s books and records. During a subsequent SEC investigation, counsel was forthcoming to the SEC about documents that it uncovered over the course of its investigation, provided the SEC with a PowerPoint presentation that set forth its investigative steps and factual findings, and provided ‘oral downloads’ to the SEC of each of the 12 witness interviews it conducted. When former officers of the company were later sued in an SEC action, the defendants subpoenaed the records from the internal investigation during discovery, requesting (among other things) the law firm’s written notes and memoranda from the witness interviews that had been described to the SEC and referenced in the PowerPoint presentation. The court rejected the law firm’s argument that work-product protection still applied to the interview memoranda, finding that counsel’s oral disclosures of their contents was the ‘functional equivalent’ of giving the SEC the memoranda themselves, removing any protection from them. It acknowledged that the outcome may have been different had the external law firm only provided ‘vague references’ to the contents of the memorandum, or ‘conclusions or general impressions’ that were free of detail.[131] The court, reflecting the fact-specific nature of these determinations, however, did not find a broader subject matter waiver to the other findings referenced in counsel’s presentation.

In In re Grand Jury Investigation,[132] in the context of the US Special Counsel’s Office (SCO) investigation of foreign interference in the 2016 presidential election, the SCO uncovered evidence that Paul Manafort (President Donald Trump’s former campaign manager), his lobbying company and its employees made false statements in two letters submitted to the Foreign Agent Registration Act Registration Unit. In the first letter, counsel made factual representations that her clients did not have any agreements to provide services to a foreign entity. In the follow-up letter, counsel represented that one client could ‘recall interacting’ with consultants for a foreign entity, but did not recall meeting with or conducting outreach or facilitating any phone calls. The grand jury subsequently subpoenaed the attorney to testify about the communications underlying the factual representations in the letters. The attorney refused to answer the questions, citing the attorney–client privilege and work-product protection. The court found that counsel had waived, through voluntary disclosure, all the attorney–client privilege as to the contents of the letters, which ‘made specific factual representations’ that are ‘unlikely to have originated from sources other than the Targets, and, in large part, were attributed to the Targets’ recollections’,[133] and extended the waiver to all communications on that same subject matter. The court also found that the crime-fraud exception provided an independent basis for waiver of privilege with respect to several of the questions posed to counsel in the grand jury.[134]

Some courts have suggested that production pursuant to a valid confidentiality agreement entered into with the government prior to the disclosure of attorney–client privileged or work-product information effectively preserves the privilege and does not amount to a waiver as to third parties.[135] Consequently, if the company intends to disclose privileged material to the government, it should first attempt to obtain such an agreement from the government that it will keep the information confidential (a McKesson letter).[136] But even though future plaintiffs would not be parties to such an agreement, some courts have still found that the production of privileged materials pursuant to confidentiality agreements with the government nonetheless constitutes a waiver.[137]

In light of federal courts’ reluctance to find selective waiver, when a company voluntarily discloses documents or communications to government agencies, it must do so with the understanding that the documents and communications may lose the protection of the privilege and be subject to discovery by other parties, including private litigants.[138]

19.7 Crime-fraud exception

The attorney–client privilege does not offer absolute protection for all of a lawyer’s communications with the client. An important exclusion is the crime-fraud exception, which removes the protection of the attorney–client privilege for communications concerning contemplated or continuing illegal or fraudulent acts.[139]

After a party has invoked the attorney–client privilege, the party seeking to abrogate the privilege under this exception has the burden of making a prima facie case that (1) the client was committing or intending to commit a crime or fraud and (2) the attorney–client communications at issue were in furtherance of that alleged crime or fraud.[140] Significantly, for the exception to be applicable, the party need not show that the alleged crime or fraud was actually completed – only that the crime or fraud was the objective of the communication.[141] This applies even if the communication ultimately does not further the crime or even hinders the crime.[142] Further, the party need not show that the attorney was aware of the alleged fraud or misconduct; in fact, the attorney’s knowledge or ignorance of the crime is irrelevant. Instead, courts look to the client’s intent or objective in the subject communication.[143] As the Supreme Court stated in Clark v. United States: ‘A client who consults an attorney for advice that will serve him in the commission of a fraud will have no help from the law. He must let the truth be told.’[144]

For example, in the case of United States v. Gorski,[145] a defendant was indicted for making fraudulent representations related to the ownership and control of his company when bidding on government contracts.[146] The government alleged that the defendant fraudulently represented that his business qualified as a service-disabled veteran-owned small business entity[147] and also sought to restructure his company through backdated documents to give the appearance of compliance with ownership regulations.[148] In response to a government subpoena for access to communications between the defendant and his lawyer regarding the ownership and restructuring efforts, the trial court held an in camera review and ex parte hearing, and determined that the requested documents should be produced under the crime-fraud exception.[149]

On appeal, the First Circuit upheld the trial court’s ruling, finding that (1) the indictment provided a reasonable basis to believe that the defendant was engaged in criminal or fraudulent activity and (2) there was a reasonable basis to believe that the attorney–client communications ‘were intended by the client to facilitate or conceal the criminal or fraudulent activity’.[150] In so ruling, it specifically noted that the crime-fraud exception does not require, and therefore does not reflect, any finding on the ultimate question as to whether the defendant acted wrongfully, nor does it bear on the conduct or intent of the lawyers involved.[151]

The crime-fraud exception has also been found to apply because of an attorney’s misconduct, even if the client is found to be innocent of any wrongdoing.[152] The exception does not apply to attorney–client communications that reflect the solicitation or provision of legal advice concerning crimes or frauds that occurred in the past; such attorney–client communications remain protected,[153] unless the communications are made for the purpose of covering up past misconduct or obstructing justice.[154] Attorney–client communications reflecting advice about the legality of a client’s intended course of conduct are likewise protected as privileged.[155] Finally, communications where an attorney dissuades or prevents the client from engaging in further illegal conduct are also protected; such communications are viewed as serving an important purpose in the administration of justice by promoting legal conduct.[156]

Some circuits have held that the crime-fraud exception not only applies to attorney-client privilege but also to work-product protection.[157] Like the application of the crime-fraud doctrine to the attorney-client privilege, the crime-fraud exception to the work-product doctrine applies when the documents created by or at the direction of the attorney are made for the purposes of furthering a crime.[158]

19.8 Taint teams

When a practising attorney’s communications or work-product is seized as part of a government investigation, the DOJ has traditionally used an independent team called a ‘taint team’ to conduct an initial review of the documents to ensure there is no violation of the attorney–client privilege.[159] Taint teams are staffed with federal prosecutors and agents who are not otherwise involved with the underlying investigation.[160] The team’s role is to perform a preliminary review of the materials that have been seized to filter out attorney–client privileged communications before the materials are reviewed by the investigating team.[161]

Courts have scrutinised the DOJ’s use of taint teams, identifying the potential for leaks of confidential information and the inherent conflict created when the same government office responsible for the review of the privileged materials has an interest in prosecuting the subject.[162] In rejecting the use of a government taint team for a privilege review, the Fourth Circuit observed that:

prosecutors have a responsibility to not only see that justice is done, but to also ensure that justice appears to be done. . . . Federal agents and prosecutors rummaging through law firm materials that are protected by attorney–client privilege and the work-product doctrine is at odds with the appearance of justice.[163]

When the independence or propriety of a taint team is challenged, some courts have removed the task of reviewing the potential attorney–client documents from the purview of the DOJ, assigning the process to be governed by an independent, court-appointed official, such as a magistrate judge or a special master.[164]

In the face of scrutiny, the Criminal Division of the DOJ created a Special Matters Unit within the Fraud Section to standardise the use of taint teams. Attorneys in this unit work full-time – rather than ad hoc – to ‘conduct, supervise, and litigate legal privilege matters and filter reviews on behalf of the Fraud Section’s three litigating units’.[165] The Special Matters Unit’s aim is to establish a set of ‘uniform practices for handling evidence collection and review that implicate claims of attorney–client or other privileges’, addressing some of the concerns previously raised by the courts regarding the potential conflicts arising from traditional taint teams.[166] Even still, courts continue to recognise the ‘reasonably foreseeable risks to privilege’ posed by taint teams, and some courts still view such practices as a potentially improper delegation of judicial functions to the executive branch.[167]

19.9 Disclosure to third parties

Generally, the attorney–client privilege is waived if the holder of the privilege voluntarily discloses or consents to the disclosure of any significant part of the communication to a third party or stranger to the attorney–client relationship.[168] A third-party agent may have communications with an attorney that remain covered by the attorney–client privilege if the agent’s role is limited to helping a lawyer give effective advice to the client.[169] Whether disclosure to external consultants will constitute a waiver will depend on the surrounding facts and circumstances, including the purpose for the disclosure and the involvement of counsel with that third party.[170]

United States v. Kovel is the seminal case concerning the bounds of the attorney–­client privilege with respect to third-party consultants.[171] In Kovel, a law firm employed an accountant who was held in criminal contempt for refusing to testify about his conversations with the law firm’s client under a claim of privilege.[172] In considering whether the accountant had a basis to assert attorney–client privilege, the Second Circuit recognised that there are situations ‘where the lawyer needs outside help’ and found that when the accountant assists in the ‘effective consultation between the client and the lawyer which the privilege is designed to permit’, the privilege should protect the communications.[173] The Kovel court analogised the accountant’s role to that of an interpreter, which is sometimes necessary for the attorney effectively to communicate with his or her client.[174]

The Kovel doctrine has been recognised by many courts as protecting the attorney–client privilege in circumstances where a third party has specialised knowledge or skills that assist the attorney in rendering legal advice.[175] To preserve the attorney–client privilege in such circumstances, the consultant is typically appointed directly by counsel and works under counsel’s supervision. The mere hiring of the consultant through counsel, however, will not automatically cloak the third-party communications in privilege, if the consultant is otherwise performing a business function;[176] instead, the company must show that the consultant’s involvement was indispensable to – or served some specialised purpose in facilitating – the legal advice.[177]

For example, a client’s statements to a private investigator hired by the client’s attorney are often protected by the attorney–client privilege when the investigator acts as an agent of the attorney.[178] Similarly privileged (as work-product) are an investigator’s interviews to gather background information for the ­attorney.[179] If, however, the investigator is going to be a fact witness concerning the information he or she has gathered, then all aspects of the investigator’s fact gathering may be open to discovery, including statements by third parties to the investigator and the underlying factual data gathered by the investigator; therefore, any work-product privilege that might have protected that information is waived by virtue of the private investigator’s decision to testify.[180]

Courts have also extended the attorney–client privilege to include public relations (PR) consultants under certain circumstances.[181] In particular, communications with PR consultants have been found to maintain privilege if the primary purpose of the communication was to aid in the rendering of legal advice.[182] Such communications are found within the bounds of the attorney–client privilege if the consultant provides services necessary to promote the attorney’s effectiveness in the client’s legal representation or the consultant is essentially an extension of the attorney under agency principles, or both.[183]

Even with this guidance, the extent to which PR consultants come within the bounds of the attorney–client privilege is often unclear. For example, in Calvin Klein Trademark Trust v. Wachner, a court in the Southern District of New York refused to extend the attorney–client privilege to protect documents and testimony sought from Robinson Lerer & Montgomery (RLM), a PR firm retained by counsel to Calvin Klein.[184] In so ruling, the court held, inter alia, that the ‘possibility’ that communications between counsel and RLM might help counsel formulate legal advice was ‘not in itself sufficient to implicate the privilege’,[185] and that extending the privilege to the documents and communications at issue would apply the privilege too broadly because RLM did not appear to perform functions ‘materially different from those that any ordinary PR firm would have performed’.[186]

A few months later, in In re Copper Market Antitrust Litigation, a different judge from the same district court reached the exact opposite conclusion regarding the same PR firm, finding that RLM acted as the company’s ‘spokesperson’ when dealing with issues related to a copper trading scandal, and frequently conferred with counsel.[187] Under these facts, the court found that RLM acted as the ‘functional equivalent of an in-house public-relations department with respect to Western media relations’ and therefore found that the communications between RLM, the company and counsel were made for the purpose of facilitating the provision of legal advice.[188]

Similarly, in FTC v. GlaxoSmithKline, the US Court of Appeals for the DC Circuit found that communications with a PR firm were protected by the privilege.[189] In so ruling, the court adopted the Copper Market court’s rationale, crediting a party affirmation that the consultant became an ‘integral member of the team assigned to deal with the issues [that] . . . were completely intertwined with [the client’s] litigation and legal strategies’;[190] therefore, to improve the likelihood that communications with a PR firm will be cloaked in the attorney–­client privilege, the firm should interact regularly with counsel and act as an agent at counsel’s direction.[191]

There are a growing number of federal courts declining to extend the attorney–client privilege or work-product protection to forensic reports and related communications following data security breaches. For example, in Rutter’s,[192] in response to notifications about potentially suspicious trans­action activity, Rutter (a point-of-sale payments provider) hired outside counsel regarding its potential notification obligations and also a third-party security firm ‘to conduct forensic analyses on Rutter’s card environment and determine the character and scope of the incident’. When plaintiffs in litigation later sought production of the security firm’s written report and related communications, the court determined that the work-product privilege did not apply because, among other things, litigation was not explicitly contemplated at the time the security firm was retained; and the record did not indicate that the report was reviewed by outside counsel before going to the client once the analysis was complete. The court found that the attorney–client privilege similarly did not apply because the security firm’s statement of work focused on data collection, as to whether IT equipment had been compromised, and the related communications were factual in nature or otherwise did not implicate legal advice. The court found that the report and the related communications therefore did not have the primary purpose of providing or obtaining legal assistance and were therefore not protected from disclosure.[193]

In sum, a party claiming the benefit of the attorney–client privilege has the burden of establishing all the essential elements to qualify for the protections of the privilege.[194] An attorney who wishes to consult with a non-attorney professional must seek to establish that the third party’s involvement will facilitate legal advice from the beginning of the engagement.[195]

To support its claim that communications with, and documents generated by, a third-party consultant are protected under the attorney–client relationship, counsel should memorialise the nature of the consultant’s engagement in a Kovel letter. The letter should (1) state that counsel is retaining the consultant to assist with the provision of legal advice to the client, (2) instruct the consultant about specific tasks to be performed in support of the provision of that legal advice, (3) state that all work-product generated under the scope of the engagement is the property of counsel and (4) instruct the consultant to maintain the confidentiality of all information received or created in the course of the engagement. Further, the consultant should be guided in his or her actions by the attorney, rather than independently by the client.

19.9.1 Disclosure to the company’s auditors

The disclosure of attorney–client privileged information to a company’s external auditors ordinarily constitutes a subject-matter privilege waiver.[196] To the extent that counsel anticipates that the company’s external auditors may require information about the status of an ongoing investigation, counsel should be prepared to communicate with auditors in a way that will limit any waiver of privilege. For example, counsel may provide the external auditor with detailed information about the investigative process – including the structure, the personnel involved, the document preservation steps that were taken, general information about the process of reviewing documents and conducting interviews, and external consultants employed to assist in the investigation – which may provide the external auditors with a level of comfort about the comprehensive nature of the investigative process, without waiving the privilege regarding the substance of the investigation.

While the disclosure of privileged information to auditors will likely waive the attorney–client privilege, work-product protection may remain intact if the auditor’s interests are found not to be ‘adverse’ to the client. For instance, in Merrill Lynch & Co v. Allegheny Energy Inc,[197] Allegheny sought to compel discovery of two internal investigation reports (prepared by counsel) that Merrill Lynch had disclosed to its auditor, arguing that the disclosure constituted a waiver of any applicable privilege.[198] The court disagreed, stating that the ‘critical inquiry’ is whether the auditors ‘should be conceived of as an adversary or a conduit to a potential adversary’.[199] It held that ‘any tension between an auditor and a corporation that arises from an auditor’s need to scrutinize and investigate a corporation’s records and book-keeping practices simply is not the equivalent of an adversarial relationship contemplated by the work-product doctrine’.[200] Consistent with the Allegheny court’s guidance, if the client cannot avoid disclosure of privileged information to its auditors, counsel may be able to argue in subsequent civil litigation that work-product protection remains intact under this principle.

19.9.2 Disclosure to foreign governments

When analysing issues of waiver surrounding productions to foreign governments, US courts tend to focus on whether the production of privileged material was compelled or voluntary. Where the submission is compelled or where there was no opportunity to assert the privilege, US courts will generally find that the privilege was not waived.[201]

19.10 Expert witnesses

Where government investigations involve complex financial transactions and other areas requiring specialised knowledge, counsel will often retain experts during the investigative stage to assist in their assessment of potential liability and in the building of the defence case. As with any external consultants, counsel should take steps to clarify that experts are being retained to assist counsel in their provision of legal advice, to maintain privilege over communications with the expert and their underlying analysis.

In the context of a criminal action that may follow an internal investigation, unless counsel determines that it would be advantageous to present expert analysis in conjunction with a report of its investigative findings to the government or regulatory authority, consulting expert materials will otherwise remain shielded from discovery as attorney–client privileged materials. If the defence intends to call an expert witness at trial, however, counsel may be obliged – at the government’s request – to provide a written summary of the testimony that the defendant intends to offer at trial.[202] Further, while Federal Rule of Criminal Procedure 16 contemplates that the expert’s underlying memoranda and other documents created during the case investigation will remain protected from disclosure,[203] counsel will still be required to produce documents that may qualify as ‘statements’ of a testifying expert under Federal Rule 26.2 prior to trial.[204]

In the context of civil litigation that may follow an internal investigation, however, expert discovery will be governed by Federal Rule of Civil Procedure 26. Prior to 2010, there was a significant risk that any documents provided to a testifying expert witness would be discoverable under Federal Rule 26, even if they were previously considered attorney–client privileged.[205] But the 2010 amendments to the rule made significant changes that strictly limited the discovery of communications between counsel and experts, including the discovery of draft expert reports. For example, Federal Rule 26(b)(4)(B) was added to provide work-product protection for drafts of expert reports or disclosure.[206] In addition, Federal Rule 26(b)(4)(C) was added to provide work-product protection for attorney–expert communications.[207] These amendments to Rule 26 were designed to protect counsel’s work-product and ensure that lawyers may interact with experts ‘without fear of exposing those communications to searching discovery’.[208]

Although the 2010 amendments provide significant protection for expert drafts and attorney–expert communications, counsel should still make efforts to limit the scope of potential disclosure by effectively managing a testifying expert’s access to information and the development of the expert’s opinions. For example, Federal Rule 26 does not preclude discovery of facts or data provided to the expert by an attorney, such as fact work-product prepared for the expert by counsel.[209]Consequently, counsel should create an inventory of all factual materials provided to a testifying expert and ensure that all such factual materials are accurate and final, and that such materials have been produced or are otherwise matters of public record.

Further, where the committee notes accompanying Federal Rule 26 extend to ‘any materials considered by’ an expert, counsel should ensure that all the facts made available to a testifying expert are based on the record in the case, rather than as the result of attorney–client privileged communications.

Finally, while the amendment to Federal Rule 26 protects drafts of expert reports from disclosure, state court rules of civil procedure may vary as to whether such drafts are discoverable.[210] If there is any question as to whether drafts of an expert report may be discoverable, especially if the matter is pending in a jurisdiction governed by state law, it may be advisable to negotiate a stipulation that explicitly extends the protection of the Federal Rules to expert discovery.

[138] Banks, in particular, often face pressure to share privileged materials with the government, both in the context of enforcement actions aimed at suspected wrongdoing and during routine regulatory oversight. With respect to US bank regulatory supervision, as a statutory matter, sharing privileged materials with bank supervisors results in a waiver of privilege only with respect to those supervisors; it does not waive applicable privileges with respect to third parties. Under Section 1828(x) of the Regulations Governing Insured Depository Institutions, the submission of information to ‘the Bureau of Consumer Financial Protection, any [f]ederal banking agency, [s]tate bank supervisor, or foreign banking authority for any purpose in the course of any supervisory or regulatory process’ shall not be construed as waiving privilege ‘as to any person or entity other than such agency, supervisor, or authority’. 12 U.S.C. § 1828(x). This approach provides one of the few examples of federal statutes that explicitly contemplate selective waiver of the attorney–client privilege. Section 1828(x)’s companion statute, 12 U.S.C. § 1785(j), applies the same rule to credit unions.

Zolin, 491 U.S. 554, 563 (1989) (explaining that the crime-fraud exception ‘assure[s] that the seal of secrecy between lawyer and client does not extend to communications made for the purpose of getting advice for the commission of a fraud or crime’) (citation omitted); Clark v.

Va. 20 Apr. 2020) (finding that ‘the crime-fraud exception can apply where, as here, the attorney alone purportedly committed a crime or fraud of which the client was a victim’)).

[153] See, e.g., Zolin, 491 U.S. at 562 (explaining that the crime-fraud exception applies ‘where the desired advice refers not to prior wrongdoing, but to future wrongdoing’) (citation omitted).

[154] See, e.g., In re Grand Jury Proceedings, 102 F.3d 748, 751 (4th Cir. 1996) (noting that the crime-fraud exception includes ‘concealment or cover-up of [the client’s] criminal or fraudulent activities’); United States v. Laurins, 857 F.2d 529, 540 (9th Cir. 1988) (‘Obstruction of justice is an offense serious enough to defeat the privilege’).

[155] If a client seeks advice from counsel about the legality of a course of conduct and then relies to his or her detriment on that advice in taking action later determined to be unlawful, the client may choose to assert an ‘advice of counsel’ defence to demonstrate a lack of wrongful intent. The client generally must show (1) full disclosure of all material facts to the attorney before seeking advice and (2) actual reliance on counsel’s advice in the good faith belief that the conduct was legal. See, e.g., United States v. West, 392 F. 3d 450, 457 (D.C. Cir. 2004). Invoking the ‘advice of counsel’ defence generally waives the attorney–client privilege protecting the underlying communications with counsel related to the advice, since the client is putting the contents of those communications at issue. See, e.g., Chevron Corp. v. Pennzoil Co., 974 F.2d 1156, 1162–63 (9th Cir. 1992).

There are limits to the ability of an individual employee to assert the advice-of-counsel defence where the client is the company, rather than the individual. In the civil context, for example, if the corporation controls the privilege over the attorney advice at issue, at least one court has found that the company may refuse to waive that privilege on behalf of the individual employee, even if the disclosure would amount to a complete defence of the individual. See United States v. Wells Fargo Bank, N.A., 132 F. Supp. 3d 558, 566 (S.D.N.Y. 2015). In the criminal context, however, there appears to be split authority as to whether an individual’s right to present his defence may trump the company’s interest in preserving the privilege. Compare United States v. Grace, 439 F. Supp.2d 1125, 1142 (D. Mont. 2006) (finding that such evidence may be ‘of such probative and exculpatory value as to compel the admission of the evidence over [the company’s] objection as the attorney–client privilege holder’), with Wells Fargo Bank, N.A., 132 F. Supp 3d at 562–63 (suggesting that the Supreme Court’s rejection of a ‘balancing test’ for attorney–client privilege in Swidler & Berlin v. United States, 524 U.S. 399 (1998), may extend to criminal cases as well).

[162] See In re Grand Jury Subpoenas, 454 F.3d 511, 523 (6th Cir. 2006) (‘Furthermore, taint teams present inevitable, and reasonably foreseeable, risks to privilege, for they have been implicated in the past in leaks of confidential information to prosecutors. That is to say, the government taint team may have an interest in preserving privilege, but it also possesses a conflicting interest in pursuing the investigation, and, human nature being what it is, occasionally some taint-team attorneys will make mistakes or violate their ethical obligations. It is thus logical to suppose that taint teams pose a serious risk to holders of privilege, and this supposition is substantiated by past experience’).
