Guarding Against Defamation and Other Tort Liability in Internal Corporate Investigations

Internal corporate investigations can expose corporations and their counsel to potential tort liability, particularly claims for defamation and related causes of action. Individuals who are criticized in investigation reports or referenced in regulatory filings may allege libel, slander, interference with economic interests, or emotional distress. Because these claims often arise after an investigation concludes, companies should structure investigations and reports carefully to reduce exposure. Courts recognize certain privileges that protect investigative communications, but those protections have limits. As a result, organizations conducting investigations should focus on maintaining objectivity, protecting confidentiality, and ensuring that investigative findings are presented in a balanced and accurate manner.
