Maintaining Independence and Objectivity in Internal Investigations


Independence and objectivity are critical to the credibility of any internal investigation. If stakeholders perceive any bias or undue influence, the investigation’s findings might be compromised, and the company’s reputation could suffer. Ensuring impartiality requires thoughtful planning around who conducts the investigation, appropriate reporting lines within the company, and maintaining confidentiality throughout the process.

Best practices include selecting investigators who are not directly involved in the subject matter and ensuring that they report to the board of directors or someone within the company who does not have a personal stake in the outcome. The investigators should also establish clear protocols for obtaining and handling evidence and ensuring that witness interviews remain confidential. In many cases, engaging outside counsel can help reinforce the investigation’s independence and provide an added layer of credibility.
