When the investigation becomes evidence
Investigations into accounting, harassment, bribery, or safety concerns often run alongside litigation or ahead of it. Shareholders may seek the report in a derivative suit, a terminated employee may claim the investigation was a pretext for retaliation, and agencies may ask what the company found. Whether the materials stay protected generally depends on whether lawyers directed the work for the purpose of legal advice, and on what the company later does with the findings. Sharing conclusions with auditors, regulators, or the public can put privilege at risk, and courts do not all draw that line in the same place. Relying on the investigation as a defense can also open it to discovery.
Building a file that holds up
The engagement terms matter from the first day: who retained counsel, on whose behalf, and for what purpose. Interview memoranda prepared by counsel tend to receive more protection than recordings or summaries written by business staff. Employees who are interviewed should be told that the lawyer represents the company rather than them, often called an Upjohn warning, and that the company may choose to share what they say. Litigation holds should go out early and reach messaging apps and personal devices used for work, not only company email. If you are an employee asked to sit for an interview, it is reasonable to ask whether you should have your own counsel.
Choices made at the outset
In an early meeting we map the investigation against every proceeding that is pending or likely, because a choice made for one can affect the others. For a company, that often means deciding how findings will be reported to the board, whether any disclosure to a regulator is planned, and how to keep business advice separate from legal advice in the file. For an individual, it means understanding whether you are a witness or something closer to a subject, and whether your interests and the company's have begun to diverge. These decisions are much easier to control before a subpoena or a motion to compel arrives.
