Independent Investigations: When to Bring in Outside Counsel

When allegations implicate a C-suite executive or board member, your first instinct might be to handle it quietly. That instinct can destroy your credibility with regulators and expose your organization to claims of bias. This guide outlines when you need independent counsel, how to structure the engagement, and what privilege traps to avoid.

Scope: What This Guide Covers

This guide addresses internal investigations requiring outside counsel to maintain credibility. It's designed for compliance officers, general counsel, and governance professionals who need to decide between internal and independent investigations, then manage the process without undermining privilege.

We focus on three scenarios: allegations involving senior management, matters likely to attract DOJ or SEC scrutiny, and cases where litigation or financial restatements are anticipated.

Key Concepts and Definitions

Independent Investigation: An inquiry conducted by external counsel who reports to the board or an independent committee, not to management. The structure matters as much as the substance.

Upjohn Warnings: Mandatory disclosures at the start of witness interviews clarifying that (1) counsel represents the organization, not the individual, (2) the conversation is privileged, and (3) the organization holds the privilege and may waive it.

Privilege Waiver Risk: Voluntary disclosure of privileged materials to regulators may constitute waiver as to third parties, not just the government. Your disclosure strategy needs to be deliberate, not reactive.

When Independence Becomes Non-Negotiable

Independent counsel is necessary when:

• Allegations implicate senior management: C-suite executives, board members, or anyone with authority over compliance functions. An internal team reporting to these individuals can't credibly investigate them.

• Regulatory scrutiny is likely or active: If the DOJ, SEC, or state attorneys general are watching or will be, an independent investigation shows you're conducting a thorough, unbiased review.

• Financial restatements are possible: The intersection of accounting integrity and potential misconduct requires separation from management influence.

• Whistleblower complaints are significant: Especially when they allege systemic failures or retaliation.

• Litigation is anticipated or filed: Work product doctrine becomes critical, and independence strengthens your position.

The perceived independence of your investigation can matter more than the findings themselves when regulators evaluate your response.

Structuring the Investigation

Selecting Outside Counsel

Look beyond your usual outside counsel relationships if independence could be questioned. Your criteria:

• Deep experience in internal investigations and familiarity with the relevant regulatory landscape
• No conflicts with potential subjects or the company's regular business
• Credibility with the specific regulators who might scrutinize this matter
• Clear engagement terms defining scope, responsibilities, and reporting lines

Conduct thorough conflicts checks before engagement. A firm that represents your CEO in personal matters or handles your routine commercial work isn't independent.

Establishing Reporting Lines

Outside counsel must report to the board of directors, an independent committee, or a specially formed committee. Not to management. This reporting structure isn't cosmetic; it insulates findings from accusations of bias.

Work with the committee to define:

• Investigation scope (broad enough to address core allegations and related conduct, focused enough to stay manageable)
• Committee authority and decision rights
• Process for flagging scope questions in real time
• Documentation of the company's reason for the investigation (critical for privilege protection later)

Document the scope in writing at the outset. Revisit it as new facts emerge. Overly narrow scoping risks missing related misconduct; unbounded investigations drain resources and delay resolution.

Your Role: Facilitating Without Compromising

Document Preservation and Collection

Issue litigation hold notices immediately to all relevant custodians. Your notice must be clear, comprehensive, and promptly distributed. Coordinate with outside counsel and forensic vendors to ensure defensibility.

Pay particular attention to:

• Ephemeral messaging platforms (Slack, Teams disappearing messages)
• Personal devices under bring-your-own-device policies
• Cloud-based repositories
• AI-based programs like Copilot or ChatGPT (increasingly common evidence sources and frequent subjects of regulatory inquiry)

If the investigation involves extremely sensitive subject matter, suspend routine deletion from the back-end through IT vendors rather than broadcasting a hold to custodians.

Witness Interview Support

You're best positioned to identify custodians, locate data sources, and facilitate access. Witnesses are more receptive to cooperating when introduced by in-house counsel.

Your logistical responsibilities:

• Provide appropriate private space for interviews
• Ensure the setting preserves confidentiality and minimizes risk that other employees learn who's being interviewed
• Impress upon witnesses the importance of not sharing interview substance with other potential fact witnesses
• Include copies of retaliation or whistleblower protection policies in outreach emails

Upjohn warnings can make witnesses hesitant. Consider how you introduce outside counsel and frame the process to ensure witnesses feel protected enough to provide complete information.

Common Pitfalls

Mixing legal and business communications: When in-house counsel wears both hats, separating legal from business communications becomes critical. Mixing purposes is one of the most common ways privilege is inadvertently weakened.

Overly broad access to privileged materials: Limit the circle of individuals with access to those necessary for investigation completion. Every additional person increases waiver risk.

Failing to document the legal purpose: Your engagement letter and investigation plan should clearly state the purpose. "To obtain legal advice regarding potential compliance violations" protects privilege better than "to review the situation."

Disclosing to regulators without a strategy: Voluntary disclosure may waive privilege as to third parties, not just the government. Develop a disclosure strategy identifying what can be shared without waiving privilege, what requires a confidentiality agreement or common interest arrangement, and what should be withheld.

Choosing written reports by default: Written reports create detailed records but also discoverable documents if privilege is waived or challenged. Oral presentations preserve flexibility. Your choice depends on the anticipated regulatory posture and litigation landscape.

Quick Reference Table

The credibility of your investigation depends on decisions you make in the first 48 hours. Get the structure right, and you create a defensible record. Get it wrong, and even solid findings won't protect you from claims of bias or privilege challenges.
